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. 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- **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 T0837 Loss of Protection\n**ATT&CK T0837 Loss of Protection (full record).** Adversaries may compromise protective system functions designed to prevent the effects of faults and abnormal conditions. This can result in equipment damage, prolonged process disruptions and hazards to personnel.\n\nMany faults and abnormal 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 protective system functions as a prerequisite to subsequent attack execution or to allow for future faults and abnormal conditions to go unchecked. Detection of a Loss of Protection by operators can result in the shutdown of a process due to strict policies regarding protection 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**Detection strategies and analytics.** - **Detection of Loss of Protection**\n  - No standard detection method currently exists for this technique. (telemetry: )\n\n**Tracked users (groups, malware, tools).** - Industroyer (malware): Industroyer is a sophisticated malware framework designed to cause an impact to the working processes of Industrial Control Systems (ICS), specifically components used in electrica.\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. […]\n\n## Reference: ATT&CK T0840 Network Connection Enumeration\n**ATT&CK T0840 Network Connection Enumeration (full record).** Adversaries may perform network connection enumeration to discover information about device communication patterns. If an adversary can inspect the state of a network connection with tools, such as Netstat, in conjunction with System Firmware, then they can determine the role of certain devices on the network. The adversary can also use Network Sniffing to watch network traffic for details about the source, destination, protocol, and content.\n\n**Classification.** - Tactics: discovery\n- Platforms: Embedded, Windows, Linux, Network Devices\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 Network Connection Enumeration**\n  - Real-time monitoring identifies execution of network enumeration commands (netstat, arp -a, Get-NetTCPConnection) on an Industrial Control System (ICS) host from an account not associated with documented network administration, where multiple such commands execute in sequence within a short window.

Virtual machine software protection translates an executable's original code into a special format that only a special virtual machine can run. A virtual machine is then called to run this code.\n\nUtilities used to perform software packing are called packers. Example packers are MPRESS and UPX.

[…]\n\n## Reference: ATT&CK T1027.003 Steganography\n**ATT&CK T1027.003 Steganography (full record).** Adversaries may use steganography techniques in order to prevent the detection of hidden information. Steganographic techniques can be used to hide data in digital media such as images, audio tracks, video clips, or text files.\n\nDuqu was an early example of malware that used steganography. It encrypted the gathered information from a victim's system and hid it within an image before exfiltrating the image to a C2 server.\n\nBy the end of 2017, a threat group used `Invoke-PSImage` to hide PowerShell commands in an image file (.png) and execute the code on a victim's system. In this particular case the PowerShell code downloaded another obfuscated script to gather intelligence from the victim's machine and communicate it back to the adversary.\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**Detection strategies and analytics.** - **Detection Strategy for Steganographic Abuse in File & Script Execution**\n  - Detects execution of image viewers or PowerShell scripts accessing or decoding files with mismatched MIME headers or embedded script-like byte patterns; often correlated with suspicious parent-child process lineage and outbound connections. (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=3, 22, WinEventLog:Security:EventCode=4663, 4670, 4656)\n  - Detects access to media files followed by execution of scripts (bash, Python, etc.) referencing those same files, or outbound traffic triggered shortly after file read. Correlates unusual use of tools like `steghide`, `exiftool`, or image libraries. […]\n\n## Reference: ATT&CK T1027.004 Compile After Delivery\n**ATT&CK T1027.004 Compile After Delivery (full record).** Adversaries may attempt to make payloads difficult to discover and analyze by delivering files to victims as uncompiled code. Text-based source code files may subvert analysis and scrutiny from protections targeting executables/binaries. These payloads will need to be compiled before execution; typically via native utilities such as ilasm.exe, csc.exe, or GCC/MinGW.\n\nSource code payloads may also be encrypted, encoded, and/or embedded within other files, such as those delivered as a Phishing. Payloads may also be delivered in formats unrecognizable and inherently benign to the native OS (ex: EXEs on macOS/Linux) before later being (re)compiled into a proper executable binary with a bundled compiler and execution framework.\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**Detection strategies and analytics.** - **Detection Strategy for Compile After Delivery - Source Code to Executable Transformation**\n  - Detects compilation activity using csc.exe, ilasm.exe, or msbuild.exe initiated by user-space processes outside typical development environments, followed by execution or network activity from newly written binaries. (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=11, WinEventLog:Sysmon:EventCode=3, 22)\n  - Detects GCC or Clang invoked on suspicious file paths (e.g., /tmp/, ~/Downloads) with output to executable binaries, followed by execution or outbound traffic from these binaries. […]\n\n## Reference: ATT&CK T1027.005 Indicator Removal from Tools\n**ATT&CK T1027.005 Indicator Removal from Tools (full record).** Adversaries may remove indicators from tools if they believe their malicious tool was detected, quarantined, or otherwise curtailed. They can modify the tool by removing the indicator and using the updated version that is no longer detected by the target's defensive systems or subsequent targets that may use similar systems.\n\nA good example of this is when malware is detected with a file signature and quarantined by anti-virus software. An adversary who can determine that the malware was quarantined because of its file signature may modify the file to explicitly avoid that signature, and then re-use the malware.\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**Detection strategies and analytics.** - **Detection Strategy for Indicator Removal from Tools - Post-AV Evasion Modification**\n  - Detection of known tools or malware flagged by antivirus, followed by a near-term drop of a similar binary with modified signature and resumed activity (execution, C2, or persistence). (telemetry: WinEventLog:Application:EventCode=1000, WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=11)\n  - Detection of anti-malware quarantining or flagging a tool, followed by a new binary written to disk with a similar function or name and a resumed process chain.

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. […]\n\n## Reference: ATT&CK T1092 Communication Through Removable Media\n**ATT&CK T1092 Communication Through Removable Media (full record).** Adversaries can perform command and control between compromised hosts on potentially disconnected networks using removable media to transfer commands from system to system. Both systems would need to be compromised, with the likelihood that an Internet-connected system was compromised first and the second through lateral movement by Replication Through Removable Media. Commands and files would be relayed from the disconnected system to the Internet-connected system to which the adversary has direct access.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Linux, macOS, 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- **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\n**Detection strategies and analytics.** - **Cross-host C2 via Removable Media Relay**\n  - Behavioral sequence where removable media is mounted, files are written/updated, and subsequently read/executed on a separate host, suggesting removable-media relay communication.

HTML documents can store large binary objects known as JavaScript Blobs (immutable data that represents raw bytes) that can later be constructed into file-like objects. Data may also be stored in Data URLs, which enable embedding media type or MIME files inline of HTML documents. HTML5 also introduced a download attribute that may be used to initiate file downloads.\n\nAdversaries may deliver payloads to victims that bypass security controls through HTML Smuggling by abusing JavaScript Blobs and/or HTML5 download attributes. Security controls such as web content filters may not identify smuggled malicious files inside of HTML/JS files, as the content may be based on typically benign MIME types such as `text/plain` and/or `text/html`. Malicious files or data can be obfuscated and hidden inside of HTML files through Data URLs and/or JavaScript Blobs and can be deobfuscated when they reach the victim (i.e. Deobfuscate/Decode Files or Information), potentially bypassing content filters.\n\nFor example, JavaScript Blobs can be abused to dynamically generate malicious files in the victim machine and may be dropped to disk by abusing JavaScript functions such as `msSaveBlob`.\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 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. […]\n\n## Reference: ATT&CK T1027.007 Dynamic API Resolution\n**ATT&CK T1027.007 Dynamic API Resolution (full record).** Adversaries may obfuscate then dynamically resolve API functions called by their malware in order to conceal malicious functionalities and impair defensive analysis. Malware commonly uses various Native API functions provided by the OS to perform various tasks such as those involving processes, files, and other system artifacts.\n\nAPI functions called by malware may leave static artifacts such as strings in payload files. Defensive analysts may also uncover which functions a binary file may execute via an import address table (IAT) or other structures that help dynamically link calling code to the shared modules that provide functions.\n\nTo avoid static or other defensive analysis, adversaries may use dynamic API resolution to conceal malware characteristics and functionalities. Similar to Software Packing, dynamic API resolution may change file signatures and obfuscate malicious API function calls until they are resolved and invoked during runtime.\n\nVarious methods may be used to obfuscate malware calls to API functions. For example, hashes of function names are commonly stored in malware in lieu of literal strings. Malware can use these hashes (or other identifiers) to manually reproduce the linking and loading process using functions such as `GetProcAddress` and `LoadLibrary`. These hashes/identifiers can also be further obfuscated using encryption or other string manipulation tricks (requiring various forms of Deobfuscate/Decode Files or Information during execution).\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.

Scripts and executables may contain variables names and other strings that help developers document code functionality. Symbols are often created by an operating system’s `linker` when executable payloads are compiled. Reverse engineers use these symbols and strings to analyze code and to identify functionality in payloads.\n\nAdversaries may use stripped payloads in order to make malware analysis more difficult. For example, compilers and other tools may provide features to remove or obfuscate strings and symbols. Adversaries have also used stripped payload formats, such as run-only AppleScripts, a compiled and stripped version of AppleScript, to evade detection and analysis. The lack of human-readable information may directly hinder detection and analysis of payloads.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Network Devices, 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.

Malicious hooking mechanisms may capture API or function calls that include parameters that reveal user authentication credentials. Unlike Keylogging, this technique focuses specifically on API functions that include parameters that reveal user credentials.\n\nIn Windows, hooking involves redirecting calls to these functions and can be implemented via:\n\n* **Hooks procedures**, which intercept and execute designated code in response to events such as messages, keystrokes, and mouse inputs.\n* **Import address table (IAT) hooking**, which use modifications to a process’s IAT, where pointers to imported API functions are stored.\n* **Inline hooking**, which overwrites the first bytes in an API function to redirect code flow.\n\nIn Linux and macOS, adversaries may hook into system functions via the `LD_PRELOAD` (Linux) or `DYLD_INSERT_LIBRARIES` (macOS) environment variables, which enables loading shared libraries into a program’s address space. For example, an adversary may capture credentials by hooking into the `libc read` function leveraged by SSH or SCP.\n\n**Classification.** - Tactics: collection, credential-access\n- Platforms: Windows, Linux, macOS\n- Sub-technique of: T1056 Input Capture - Adversaries may use methods of capturing user input to obtain credentials or collect information.

Information obtained could be used to gain an understanding of common software/applications running on systems within the network. Administrator or otherwise elevated access may provide better process details. 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\nIn Windows environments, adversaries could obtain details on running processes using the Tasklist utility via cmd or `Get-Process` via PowerShell. Information about processes can also be extracted from the output of Native API calls such as `CreateToolhelp32Snapshot`. In Mac and Linux, this is accomplished with the `ps` command. Adversaries may also opt to enumerate processes via `/proc`. ESXi also supports use of the `ps` command, as well as `esxcli system process list`.\n\nOn network devices, Network Device CLI commands such as `show processes` can be used to display current running processes.\n\n**Classification.** - Tactics: discovery\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n\n**Detection strategies and analytics.** - **Detection of Adversarial Process Discovery Behavior**\n  - Identifies adversary behavior that launches commands or invokes APIs to enumerate active processes (e.g., tasklist.exe, Get-Process, or CreateToolhelp32Snapshot).

These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms. Most systems come with some built-in command-line interface and scripting capabilities, for example, macOS and Linux distributions include some flavor of Unix Shell while Windows installations include the Windows Command Shell and PowerShell.\n\nThere are also cross-platform interpreters such as Python, as well as those commonly associated with client applications such as JavaScript and Visual Basic.\n\nAdversaries may abuse these technologies in various ways as a means of executing arbitrary commands. Commands and scripts can be embedded in Initial Access payloads delivered to victims as lure documents or as secondary payloads downloaded from an existing C2. Adversaries may also execute commands through interactive terminals/shells, as well as utilize various Remote Services in order to achieve remote Execution.\n\n**Classification.** - Tactics: execution\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1059.005 Visual Basic: Adversaries may abuse Visual Basic (VB) for execution.\n- T1059.002 AppleScript: 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.\n- T1059.003 Windows Command Shell: Adversaries may abuse the Windows command shell for execution. The Windows command shell (cmd) is the primary command prompt on Windows systems.\n- T1059.013 Container CLI/API: Adversaries may abuse built-in CLI tools or API calls to execute malicious commands in containerized environments.\n- T1059.004 Unix Shell: Adversaries may abuse Unix shell commands and scripts for execution.

PowerShell is a powerful interactive command-line interface and scripting environment included in the Windows operating system. PowerShell can also be installed on Linux and macOS. Adversaries can use PowerShell to perform a number of actions, including discovery of information and execution of code. Examples include the `Start-Process` cmdlet which can be used to run an executable and the `Invoke-Command` cmdlet which runs a command locally or on a remote computer (though administrator permissions are required to use PowerShell to connect to remote systems).\n\nPowerShell may also be used to download and run executables from the Internet, which can be executed from disk or in memory without touching disk.\n\nA number of PowerShell-based offensive testing tools are available, including Empire, PowerSploit, PoshC2, and PSAttack.\n\nPowerShell commands/scripts can also be executed without directly invoking the `powershell.exe` binary through interfaces to PowerShell's underlying `System.Management.Automation` assembly DLL exposed through the.NET framework and Windows Common Language Interface (CLI).\n\n**Classification.** - Tactics: execution\n- Platforms: Windows, Linux, macOS\n- Sub-technique of: T1059 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

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- **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. […]\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.

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.

Some systems may automatically restart critical applications and services when crashes occur, but they can likely be re-exploited to cause a persistent denial of service (DoS) condition.\n\nAdversaries may exploit known or zero-day vulnerabilities to crash applications and/or systems, which may also lead to dependent applications and/or systems to be in a DoS condition. Crashed or restarted applications or systems may also have other effects such as Data Destruction, Firmware Corruption, Service Stop etc. which may further cause a DoS condition and deny availability to critical information, applications and/or systems.\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. 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.\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.** - **Detection Strategy for Endpoint DoS via Application or System Exploitation**\n  - Exploitation of system or application vulnerability (e.g., CVE-based exploit) followed by service crash, restart, or repeated failure within a short time frame, impacting application/system availability.

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- **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. […]"}]}

The actions performed are likely the same types of discovery techniques depending on the operating system, but the resulting information may include details about the networked cloud environment relevant to the adversary's goals. Cloud providers may have different ways in which their virtual networks operate. Similarly, adversaries who gain access to network devices may also perform similar discovery activities to gather information about connected systems and services.\n\nUtilities and commands that acquire this information include netstat, \"net use,\" and \"net session\" with Net. In Mac and Linux, netstat and `lsof` can be used to list current connections. `who -a` and `w` can be used to show which users are currently logged in, similar to \"net session\". Additionally, built-in features native to network devices and Network Device CLI may be used (e.g. `show ip sockets`, `show tcp brief`). On ESXi servers, the command `esxi network ip connection list` can be used to list active network connections.\n\n**Classification.** - Tactics: discovery\n- Platforms: ESXi, IaaS, Linux, macOS, Network Devices, Windows\n\n**Detection strategies and analytics.** - **Detection of System Network Connections Discovery Across Platforms**\n  - Detects usage of commands or binaries (e.g., netstat, PowerShell Get-NetTCPConnection) and WMI or API calls to enumerate local or remote network connections.

They may do this, for example, by retrieving account usernames or by using OS Credential Dumping. The information may be collected in a number of different ways using other Discovery techniques, because user and username details are prevalent throughout a system and include running process ownership, file/directory ownership, session information, and system logs. Adversaries may use the information from System Owner/User 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\nVarious utilities and commands may acquire this information, including `whoami`. In macOS and Linux, the currently logged in user can be identified with `w` and `who`. On macOS the `dscl. list /Users | grep -v '_'` command can also be used to enumerate user accounts. Environment variables, such as `%USERNAME%` and `$USER`, may also be used to access this information.\n\nOn network devices, Network Device CLI commands such as `show users` and `show ssh` can be used to display users currently logged into the device.\n\n**Classification.** - Tactics: discovery\n- Platforms: Linux, macOS, Network Devices, Windows\n\n**Detection strategies and analytics.** - **Behavioral Detection of User Discovery via Local and Remote Enumeration**\n  - Adversary launches built-in system tools (e.g., whoami, query user, net user) or scripts that enumerate user account information via local execution or remote API queries (e.g., WMI, PowerShell).

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. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation.\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\n**Detection strategies and analytics.** - **Invalid Code Signature Execution Detection via Metadata and Behavioral Context**\n  - Execution of binaries with invalid digital signatures, where metadata claims code is signed but validation fails. Behavior is often correlated with suspicious parent processes or unexpected execution paths. (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Windows Defender:Operational log, WinEventLog:PowerShell:EventCode=4103, 4104, 4105, 4106)\n  - Binaries or applications executed with tampered or unverifiable code signatures. […]\n\n## Reference: ATT&CK T1036.002 Right-to-Left Override\n**ATT&CK T1036.002 Right-to-Left Override (full record).** Adversaries may abuse the right-to-left override (RTLO or RLO) character (U+202E) to disguise a string and/or file name to make it appear benign. RTLO is a non-printing Unicode character that causes the text that follows it to be displayed in reverse. For example, a Windows screensaver executable named `March 25 \\u202Excod.scr` will display as `March 25 rcs.docx`. A JavaScript file named `photo_high_re\\u202Egnp.js` will be displayed as `photo_high_resj.png`.\n\nAdversaries may abuse the RTLO character as a means of tricking a user into executing what they think is a benign file type. A common use of this technique is with Spearphishing Attachment/Malicious File since it can trick both end users and defenders if they are not aware of how their tools display and render the RTLO character. Use of the RTLO character has been seen in many targeted intrusion attempts and criminal activity. RTLO can be used in the Windows Registry as well, where regedit.exe displays the reversed characters but the command line tool reg.exe does not by default.\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.

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. This is common behavior that can be used across different platforms and the network to evade defenses.\n\n**Mitigations.** - **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- **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.

[…]\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.

[…]\n\n## Reference: ATT&CK T1027.017 SVG Smuggling\n**ATT&CK T1027.017 SVG Smuggling (full record).** Adversaries may smuggle data and files past content filters by hiding malicious payloads inside of seemingly benign SVG files. 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 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.

By doing this, an adversary’s modifications would most likely remain installed on the device for longer, allowing the adversary to continue to operate on that device.\n\nWhile there are many ways this can be accomplished, one method is by using the device’s sensors. By utilizing the various motion sensors on a device, such as accelerometer or gyroscope, an application could detect that the device is being interacted with. That way, the application could continue to run while the device is not in use but cease operating while the user is using the device, hiding anything that would indicate malicious activity was ongoing. Accessing the sensors in this way does not require any permissions from the user, so it would be completely transparent.\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.

Additionally, other applications are asked not to scan the folder with the `.nomedia` file, effectively making the folder appear invisible to the user.\n\nThis technique is often used by stalkerware and spyware applications.\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.

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.

Vulnerabilities can exist in software due to unsecure coding practices that can lead to unanticipated behavior. Adversaries can 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\nSeveral types exist:\n\n**Browser-based Exploitation.** Web browsers are a common target through Drive-by Compromise and Spearphishing Link. Endpoint systems may be compromised through normal web browsing or from certain users being targeted by links in spearphishing emails to adversary controlled sites used to exploit the web browser. These often do not require an action by the user for the exploit to be executed.\n\n**Office Applications.** Common office and productivity applications such as Microsoft Office are also targeted through Phishing. Malicious files will be transmitted directly as attachments or through links to download them. These require the user to open the document or file for the exploit to run.\n\n**Common Third-party Applications.** Other applications that are commonly seen or are part of the software deployed in a target network may also be used for exploitation. Applications such as Adobe Reader and Flash, which are common in enterprise environments, have been routinely targeted by adversaries attempting to gain access to systems. Depending on the software and nature of the vulnerability, some may be exploited in the browser or require the user to open a file. For instance, some Flash exploits have been delivered as objects within Microsoft Office documents.\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

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 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.

[…]\n\n## Reference: ATT&CK T1195.001 Compromise Software Dependencies and Development Tools\n**ATT&CK T1195.001 Compromise Software Dependencies and Development Tools (full record).** Adversaries may manipulate software dependencies and development tools 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.

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- **Vulnerability Scanning**: 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\n**Detection strategies and analytics.** - **Compromised software/update chain (installer/write → first-run/child → egress/signature anomaly)**\n  - Adversary ships a tampered application or update: an updater/installer (msiexec/setup/update.exe/vendor service) writes or replaces binaries; on first run it spawns scripts/shells or unsigned DLLs and beacons to non-approved update CDNs/hosts.

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. 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.

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.

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.

This includes protocol-based filtering, enforcing firewall rules, and blocking or restricting traffic based on predefined conditions to limit adversary movement and data exfiltration. […]"}]}

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- **Restrict Web-Based Content**: Restrict use of certain websites, block downloads/attachments, block Javascript, restrict browser extensions, etc.\n\n**Detection strategies and analytics.** - **Detection of Spearphishing Attachment**\n  - Real-time monitoring identifies an email client process on an Industrial Control System (ICS) Linux workstation spawning a child process inconsistent with normal email handling.

A common goal for post-compromise exploitation of remote services is for initial access into and lateral movement throughout the ICS environment to enable access to targeted systems.\n\nICS asset owners and operators have been affected by ransomware (or disruptive malware masquerading as ransomware) migrating from enterprise IT to ICS environments: WannaCry, NotPetya, and BadRabbit. In each of these cases, self-propagating (wormable) malware initially infected IT networks, but through exploit (particularly the SMBv1-targeting MS17-010 vulnerability) spread to industrial networks, producing significant impacts.\n\n**Classification.** - Tactics: initial-access, lateral-movement\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Vulnerability Scanning**: Vulnerability scanning is used to find potentially exploitable software vulnerabilities to remediate them.\n- **Disable or Remove Feature or Program**: Remove or deny access to unnecessary and potentially vulnerable software to prevent abuse by adversaries.\n- **Exploit Protection**: Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.\n- **Threat Intelligence Program**: A threat intelligence program helps an organization generate their own threat intelligence information and track trends to inform defensive priorities to mitigate risk.\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- **Application Isolation and Sandboxing**: Restrict the execution of code to a virtual environment on or in-transit to an endpoint system. […]\n\n## Reference: ATT&CK T0867 Lateral Tool Transfer\n**ATT&CK T0867 Lateral Tool Transfer (full record).** Adversaries may transfer tools or other files from one system to another to stage adversary tools or other files over the course of an operation. Copying of files may also be performed laterally between internal victim systems to support Lateral Movement with remote Execution using inherent file sharing protocols such as file sharing over SMB to connected network shares.\n\nIn control systems environments, malware may use SMB and other file sharing protocols to move laterally through industrial networks.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **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\n**Detection strategies and analytics.** - **Detection of Lateral Tool Transfer**\n  - Real-time monitoring identifies a file written to an Industrial Control System (ICS) host from a remote network share, where the file has an executable or script extension, immediately followed by execution of that file from the same path. Documented in the PIPEDREAM toolkit's modular design, where components transfer files to compromised Programmable Logic Controllers (PLCs) and engineering workstations. OT operational-fidelity gate: Alert only when execution violates an approved signer/hash/path/parent/process or tool allowlist, or originates from an unauthorized user/tool, and is tied to an (telemetry: WinEventLog:Security:Windows Security Event ID 5140/5145: EventCode=5145 for file write to Industrial Control Systems (ICS) host, source not in authorized file sources, WinEventLog:Sysmon:EventCode=11 with executable/script extension from remote-sourced write operation, WinEventLog:Sysmon:EventCode=1 of the newly-created file within tool transfer window of its creation)\n  - Real-time monitoring identifies execution on an ICS Linux asset of an executable or script from a path commonly used for inbound file transfer or staging, by a UID outside the approved deployment/administration baseline. […]\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. […]"}]}

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. Prior to Android 7, applications could utilize the `ps` command or examine the `/proc` directory on the device.\n\nIn iOS, applications have previously been able to use the `sysctl` command to obtain a list of running processes.

Adversaries may use the information from System Information Discovery during automated discovery to shape follow-on behaviors, including whether or not to fully infects the target and/or attempts specific actions.\n\nOn Android, much of this information is programmatically accessible to applications through the `android.os.Build` class. iOS is much more restrictive with what information is visible to applications.

[…]\n\n## Reference: ATT&CK T1428 Exploitation of Remote Services\n**ATT&CK T1428 Exploitation of Remote Services (full record).** Adversaries may exploit remote services of enterprise servers, workstations, or other resources to gain unauthorized access to internal systems once inside of a network. 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.

Examples of audio information adversaries may target include user conversations, surroundings, phone calls, or other sensitive information.\n\nAndroid and iOS, by default, require that applications request device microphone access from the user.\n\nOn Android devices, applications must hold the `RECORD_AUDIO` permission to access the microphone or the `CAPTURE_AUDIO_OUTPUT` permission to access audio output. 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.

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. With elevated privileges, an adversary may be able to access location data without explicit user consent with the `com.apple.locationd.preauthorized` entitlement key.\n\n**Classification.** - Tactics: collection, discovery\n- Platforms: Android, iOS\n\n**Sub-techniques.** - T1430.001 Remote Device Management Services: An adversary may use access to cloud services (e.g.\n- T1430.002 Impersonate SS7 Nodes: Adversaries may exploit the lack of authentication in signaling system network nodes to track the location of mobile devices by impersonating a node.\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.

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). (telemetry: AWS:CloudTrail:RunInstances, AWS:CloudTrail:CreateBucket, CloudTrail:GetCallerIdentity:GetCallerIdentity)\n\n## Reference: ATT&CK T1537 Transfer Data to Cloud Account\n**ATT&CK T1537 Transfer Data to Cloud Account (full record).** Adversaries may exfiltrate data by transferring the data, including through sharing/syncing and creating backups of cloud environments, to another cloud account they control on the same service.\n\nA defender who is monitoring for large transfers to outside the cloud environment through normal file transfers or over command and control channels may not be watching for data transfers to another account within the same cloud provider. Such transfers may utilize existing cloud provider APIs and the internal address space of the cloud provider to blend into normal traffic or avoid data transfers over external network interfaces.\n\nAdversaries may also use cloud-native mechanisms to share victim data with adversary-controlled cloud accounts, such as creating anonymous file sharing links or, in Azure, a shared access signature (SAS) URI.\n\nIncidents have been observed where adversaries have created backups of cloud instances and transferred them to separate accounts.\n\n**Classification.** - Tactics: exfiltration\n- Platforms: IaaS, Office Suite, SaaS\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 includes protecting data formats indicative of Personally Identifiable Information (PII), intellectual property, or financial data from unauthorized access, transmission, or exfiltration.\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- **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- **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic. […]\n\n## Reference: ATT&CK T1538 Cloud Service Dashboard\n**ATT&CK T1538 Cloud Service Dashboard (full record).** An adversary may use a cloud service dashboard GUI with stolen credentials to gain useful information from an operational cloud environment, such as specific services, resources, and features. For example, the GCP Command Center can be used to view all assets, review findings of potential security risks, and run additional queries, such as finding public IP addresses and open ports.\n\nDepending on the configuration of the environment, an adversary may be able to enumerate more information via the graphical dashboard than an API. This also allows the adversary to gain information without manually making any API requests.\n\n**Classification.** - Tactics: discovery\n- Platforms: IaaS, SaaS, Office Suite, Identity Provider\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 of Cloud Service Dashboard Usage via GUI-Based Cloud Access**\n  - Detects web console login events followed by read-only or metadata retrieval activity from GUI sources (e.g., browser session, mobile client) rather than API/CLI sources. Correlates across CloudTrail, IAM identity logs, and user-agent context. (telemetry: AWS:CloudTrail:ConsoleLogin, AWS:CloudTrail:Post-authentication metadata enumeration from GUI session)\n  - Detects successful login to cloud identity portals (e.g., Okta, Azure AD, Google Identity) from atypical geolocations, devices, or user agents immediately followed by dashboard/portal navigation to sensitive pages such as user or app configuration. […]\n\n## Reference: ATT&CK T1539 Steal Web Session Cookie\n**ATT&CK T1539 Steal Web Session Cookie (full record).** An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials. Web applications and services often use session cookies as an authentication token after a user has authenticated to a website.\n\nCookies are often valid for an extended period of time, even if the web application is not actively used. Cookies can be found on disk, in the process memory of the browser, and in network traffic to remote systems. Additionally, other applications on the targets machine might store sensitive authentication cookies in memory (e.g. apps which authenticate to cloud services). Session cookies can be used to bypasses some multi-factor authentication protocols.\n\nThere are several examples of malware targeting cookies from web browsers on the local system. Adversaries may also steal cookies by injecting malicious JavaScript content into websites or relying on User Execution by tricking victims into running malicious JavaScript in their browser.\n\nThere are also open source frameworks such as `Evilginx2` and `Muraena` that can gather session cookies through a malicious proxy (e.g., Adversary-in-the-Middle) that can be set up by an adversary and used in phishing campaigns.\n\nAfter an adversary acquires a valid cookie, they can then perform a Web Session Cookie technique to login to the corresponding web application.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS, Office Suite, SaaS, Windows\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- **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. […]\n\n## Reference: ATT&CK T1541 Foreground Persistence\n**ATT&CK T1541 Foreground Persistence (full record).** Adversaries may abuse Android's `startForeground` API method to maintain continuous sensor access. Beginning in Android 9, idle applications running in the background no longer have access to device sensors, such as the camera, microphone, and gyroscope. Applications can retain sensor access by running in the foreground, using Android’s `startForeground` API method. This informs the system that the user is actively interacting with the application, and it should not be killed. The only requirement to start a foreground service is showing a persistent notification to the user.\n\nMalicious applications may abuse the `startForeground` API method to continue running in the foreground, while presenting a notification to the user pretending to be a genuine application. This would allow unhindered access to the device’s sensors, assuming permission has been previously granted.\n\nMalicious applications may also abuse the `startForeground` API to inform the Android system that the user is actively interacting with the application, thus preventing it from being killed by the low memory killer.\n\n**Classification.** - Tactics: defense-evasion, persistence\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 Foreground Persistence**\n  - For Android, detect Foreground Persistence by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

Spearphishing attachments are different from other forms of spearphishing in that they employ malware attached to an email. All forms of spearphishing are electronically delivered and target a specific individual, company, or industry. In this scenario, adversaries attach a file to the spearphishing email and usually rely upon User Execution to gain execution and access.\n\nA Chinese spearphishing campaign running from December 9, 2011 through February 29, 2012, targeted ONG organizations and their employees.

A common goal for post-compromise exploitation of remote services is for initial access into and lateral movement throughout the ICS environment to enable access to targeted systems.\n\nICS asset owners and operators have been affected by ransomware (or disruptive malware masquerading as ransomware) migrating from enterprise IT to ICS environments: WannaCry, NotPetya, and BadRabbit. In each of these cases, self-propagating (wormable) malware initially infected IT networks, but through exploit (particularly the SMBv1-targeting MS17-010 vulnerability) spread to industrial networks, producing significant impacts.\n\n**Classification.** - Tactics: initial-access, lateral-movement\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Vulnerability Scanning**: Vulnerability scanning is used to find potentially exploitable software vulnerabilities to remediate them.\n- **Disable or Remove Feature or Program**: Remove or deny access to unnecessary and potentially vulnerable software to prevent abuse by adversaries.\n- **Exploit Protection**: Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.\n- **Threat Intelligence Program**: A threat intelligence program helps an organization generate their own threat intelligence information and track trends to inform defensive priorities to mitigate risk.\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- **Application Isolation and Sandboxing**: Restrict the execution of code to a virtual environment on or in-transit to an endpoint system. […]\n\n## Reference: ATT&CK T0867 Lateral Tool Transfer\n**ATT&CK T0867 Lateral Tool Transfer (full record).** Adversaries may transfer tools or other files from one system to another to stage adversary tools or other files over the course of an operation.

[…]\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. […]"}]}

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.

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`. […]\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. […]"}]}

Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private that should not be distributed. Due to how asymmetric algorithms work, 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, ElGamal, and ECDSA.\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: 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**Detection strategies and analytics.** - **Detection of Asymmetric Cryptography**\n  - For Android, detect Asymmetric Cryptography from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events. […]\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 T1526 Cloud Service Discovery\n**ATT&CK T1526 Cloud Service Discovery (full record).** An adversary may attempt to enumerate the cloud services running on a system after gaining access. These methods can differ from platform-as-a-service (PaaS), to infrastructure-as-a-service (IaaS), or software-as-a-service (SaaS). Many services exist throughout the various cloud providers and can include Continuous Integration and Continuous Delivery (CI/CD), Lambda Functions, Entra ID, etc. They may also include security services, such as AWS GuardDuty and Microsoft Defender for Cloud, and logging services, such as AWS CloudTrail and Google Cloud Audit Logs.\n\nAdversaries may attempt to discover information about the services enabled throughout the environment. Azure tools and APIs, such as the Microsoft Graph API and Azure Resource Manager API, can enumerate resources and services, including applications, management groups, resources and policy definitions, and their relationships that are accessible by an identity.\n\nFor example, Stormspotter is an open source tool for enumerating and constructing a graph for Azure resources and services, and Pacu is an open source AWS exploitation framework that supports several methods for discovering cloud services.\n\nAdversaries may use the information gained to shape follow-on behaviors, such as targeting data or credentials from enumerated services or evading identified defenses through Disable or Modify Tools or Disable or Modify Cloud Log.\n\n**Classification.** - Tactics: discovery\n- Platforms: IaaS, Identity Provider, Office Suite, SaaS\n\n**Detection strategies and analytics.** - **Detection Strategy for Cloud Service Discovery**\n  - Unusual enumeration of services and resources through cloud APIs such as AWS CLI `describe-*`, Azure Resource Manager queries, or GCP project listings.

[…]\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.

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.

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.

And as such, the topic of Intrusion Detection Systems has become one of the most prominent research topics in recent years. This paper gives an overview of the Intrusion Detection System and looks at two major machine learning paradigms used in Intrusion Detection System, Genetic Algorithms and Fuzzy Logic and how to apply them for intrusion detection.\n\nKeywords – Survey, Intrusion Detection System, Fuzzy Logic, Genetic Algorithms, Anomaly Detection ----------------------------------------------------------------------------------------------------------------------------------------------------- Date of Submission: Date Revised: Date of Acceptance: -----------------------------------------------------------------------------------------------------------------------------------------------------\n\n**1. INTRODUCTION.** With the leap in information flow across the internet, the network scale is expanding on a daily basis, and with it is increasing the threats to the systems connected to the networks. An attack on important and confidential data is one of the foremost concerns for the users. These attacks may come in various forms including hacks, virus, worms, steganography [3, 26], dictionary attacks [5, 40, 11] and denial of service attacks [36, 37] etc. With these threats looming every time a user goes online, it is important to have a mechanism that could analyze these threats and defend the system against them. Many researchers have suggested numerous techniques to deal with security threats which include multifactor authentication [16], multipath routing [14, 33, 18, 31, 21], and biometric security measures [38, 6] etc. Besides adopting these measures, conventional measures like firewalls, antiviruses, network analyzers etc. are also used. Among these, one of the most significant counter measures [10, 29, 30, 19] against security threats is the Intrusion Detection System also known as IDS. […]\n\n## Reference: Towards Steganography Detection Through Network Traffic Visualisation\nAbstract — The paper presents initial step toward new network anomaly detection method that is based on traffic visualisation. The key design principle of the proposed approach is the lack of direct, linear time dependencies for the created network traffic visualisations. The method’s feasibility is demonstrated in network steganography environment by presenting stegtomography methodology and developing the dedicated visualisation tool. To authors’ best knowledge this is the first utilization of network traffic visualisations for steganalysis purposes.\n\nsteganalysis, steganography detection, traffic visualisation I.\n\n**INTRODUCTION.** Anomalies in network traffic can be caused by malicious actions that might compromise network security. Thus, anomaly detection methods in telecommunication networks focus on finding illegal activities/events, especially those that can be caused by potential attacker/intruder. The device that offers such functionality is called Intrusion Detection/Prevention System (ID/PS) that is a vital network security component allowing the implementation of the assumed security policy. However, currently such solutions for the telecommunication networks are facing problems caused mostly by huge traffic volume that must be monitored: they are not efficient enough. And in ideal situation traffic analysis should be performed in a near realtime manner to prevent potential attacks as soon as possible. This urges to work on effective and efficient solutions for network anomaly detection. Anomalies are defined as patterns that do not conform to defined and expected established principle. The essence of the anomaly detection is a problem of finding data patters that do not fit the defined set of the expected behaviour. Anomaly detection methods have wide spectrum of applications ([1], [2]) from detection of credit card frauds, software/hardware malfunctions, military applications to detection of the malicious activities in telecommunication networks. Anomaly detection in telecommunication networks focuses on finding illegal activities/events, especially those that can be caused by potential attacker/intruder. Illegal activity includes: DoS (Denial of Service) or DDoS (Distributed DoS) attacks, network devices port scanning attempts or hacking of the security measures, hostile devices takeovers or other events that can be harmful for security policy defined for a given network. Other sources of anomalies include worms, viruses or trojans.

Badr Arab Academy for Science, Technology and Maritime Transport Cairo, Egypt\n\nMohamed A. Shaheen Arab Academy for Science, Technology and Maritime Transport Alexandria, Egypt\n\n**ABSTRACT.** Intrusion Detection System (IDS) has increasingly become a crucial issue for computer and network systems. Optimizing performance of IDS becomes an important open problem which receives more and more attention from the research community. In this work, A multi-layer intrusion detection model is designed and developed to achieve high efficiency and improve the detection and classification rate accuracy.we effectively apply Machine learning techniques (C5 decision tree, Multilayer Perceptron neural network and Naïve Bayes) using gain ratio for selecting the best features for each layer as to use smaller storage space and get higher Intrusion detection performance. Our experimental results showed that the proposed multi-layer model using C5 decision tree achieves higher classification rate accuracy, using feature selection by Gain Ratio, and less false alarm rate than MLP and naïve Bayes. Using Gain Ratio enhances the accuracy of U2R and R2L for the three machine learning techniques (C5, MLP and Naïve Bayes) significantly. MLP has high classification rate when using the whole 41 features in Dos and Probe layers.\n\n**Keywords.** Intrusion Detection, Layered Approach, Machine Learning, NSL-KDD dataset, Network Security.\n\n**1. INTRODUCTION.** The rapid development and expansion of World Wide Web and local network systems have changed the computing world in the last decade. The costs of temporary or permanent damages caused by unauthorized access of the intruders to computer systems have urged different organizations to increasingly implement various systems to monitor data flow in their networks [1]. These systems are generally referred to as Intrusion Detection Systems (IDSs).\n\nIntrusion Detection Systems have gained acceptance as a necessary addition to every organization’s security infrastructure [2]. Intrusion detection systems are classified as host based or network based IDS. […]"}]}

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`.

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.

To enable authentication, Kerberos requires that SPNs be associated with at least one service logon account (an account specifically tasked with running a service).\n\nAdversaries possessing a valid Kerberos ticket-granting ticket (TGT) may request one or more Kerberos ticket-granting service (TGS) service tickets for any SPN from a domain controller (DC). Portions of these tickets may be encrypted with the RC4 algorithm, meaning the Kerberos 5 TGS-REP etype 23 hash of the service account associated with the SPN is used as the private key and is thus vulnerable to offline Brute Force attacks that may expose plaintext credentials.\n\nThis same behavior could be executed using service tickets captured from network traffic.\n\nCracked hashes may enable Persistence, Privilege Escalation, and Lateral Movement via access to Valid Accounts.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows\n- Sub-technique of: T1558 Steal or Forge Kerberos Tickets - Adversaries may attempt to subvert Kerberos authentication by stealing or forging Kerberos tickets to enable Pass the Ticket.

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- **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. […]\n\n## Reference: ATT&CK T1558.004 AS-REP Roasting\n**ATT&CK T1558.004 AS-REP Roasting (full record).** Adversaries may reveal credentials of accounts that have disabled Kerberos preauthentication by Password Cracking Kerberos messages.\n\nPreauthentication offers protection against offline Password Cracking. When enabled, a user requesting access to a resource initiates communication with the Domain Controller (DC) by sending an Authentication Server Request (AS-REQ) message with a timestamp that is encrypted with the hash of their password. If and only if the DC is able to successfully decrypt the timestamp with the hash of the user’s password, it will then send an Authentication Server Response (AS-REP) message that contains the Ticket Granting Ticket (TGT) to the user. Part of the AS-REP message is signed with the user’s password.\n\nFor each account found without preauthentication, an adversary may send an AS-REQ message without the encrypted timestamp and receive an AS-REP message with TGT data which may be encrypted with an insecure algorithm such as RC4. The recovered encrypted data may be vulnerable to offline Password Cracking attacks similarly to Kerberoasting and expose plaintext credentials.\n\nAn account registered to a domain, with or without special privileges, can be abused to list all domain accounts that have preauthentication disabled by utilizing Windows tools like PowerShell with an LDAP filter. Alternatively, the adversary may send an AS-REQ message for each user. If the DC responds without errors, the account does not require preauthentication and the AS-REP message will already contain the encrypted data.\n\nCracked hashes may enable Persistence, Privilege Escalation, and Lateral Movement via access to Valid Accounts.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows\n- Sub-technique of: T1558 Steal or Forge Kerberos Tickets - Adversaries may attempt to subvert Kerberos authentication by stealing or forging Kerberos tickets to enable Pass the Ticket.

These files are used for short term storage of a user's active session credentials. The ccache file is created upon user authentication and allows for access to multiple services without the user having to re-enter credentials.\n\nThe `/etc/krb5.conf` configuration file and the `KRB5CCNAME` environment variable are used to set the storage location for ccache entries. On Linux, credentials are typically stored in the `/tmp` directory with a naming format of `krb5cc_%UID%` or `krb5.ccache`. On macOS, ccache entries are stored by default in memory with an `API:{uuid}` naming scheme. Typically, users interact with ticket storage using `kinit`, which obtains a Ticket-Granting-Ticket (TGT) for the principal; `klist`, which lists obtained tickets currently held in the credentials cache; and other built-in binaries.\n\nAdversaries can collect tickets from ccache files stored on disk and authenticate as the current user without their password to perform Pass the Ticket attacks. Adversaries can also use these tickets to impersonate legitimate users with elevated privileges to perform Privilege Escalation. Tools like Kekeo can also be used by adversaries to convert ccache files to Windows format for further Lateral Movement. On macOS, adversaries may use open-source tools or the Kerberos framework to interact with ccache files and extract TGTs or Service Tickets via lower-level APIs.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS\n- Sub-technique of: T1558 Steal or Forge Kerberos Tickets - Adversaries may attempt to subvert Kerberos authentication by stealing or forging Kerberos tickets to enable Pass the Ticket.

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**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1559.003 XPC Services: Adversaries can provide malicious content to an XPC service daemon for local code execution.\n- T1559.002 Dynamic Data Exchange: Adversaries may use Windows Dynamic Data Exchange (DDE) to execute arbitrary commands.\n- T1559.001 Component Object Model: Adversaries may use the Windows Component Object Model (COM) for local code execution.\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- **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. […]\n\n## Reference: ATT&CK T1559.001 Component Object Model\n**ATT&CK T1559.001 Component Object Model (full record).** Adversaries may use the Windows Component Object Model (COM) for local code execution. COM is an inter-process communication (IPC) component of the native Windows application programming interface (API) that enables interaction between software objects, or executable code that implements one or more interfaces. Through COM, a client object can call methods of server objects, which are typically binary Dynamic Link Libraries (DLL) or executables (EXE). Remote COM execution is facilitated by Remote Services such as Distributed Component Object Model (DCOM).\n\nVarious COM interfaces are exposed that can be abused to invoke arbitrary execution via a variety of programming languages such as C, C++, Java, and Visual Basic. Specific COM objects also exist to directly perform functions beyond code execution, such as creating a Scheduled Task/Job, fileless download/execution, and other adversary behaviors related to privilege escalation and persistence.\n\n**Classification.** - Tactics: execution\n- Platforms: Windows\n- Sub-technique of: T1559 Inter-Process Communication - Adversaries may abuse inter-process communication (IPC) mechanisms for local code or command execution. IPC is typically used by processes to share data, communicate with each other, or synchronize execution.\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- **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. […]"}]}

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. […]\n\n## Reference: ATT&CK T0869 Standard Application Layer Protocol\n**ATT&CK T0869 Standard Application Layer Protocol (full record).** 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. 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.

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.

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**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1559.003 XPC Services: Adversaries can provide malicious content to an XPC service daemon for local code execution.\n- T1559.002 Dynamic Data Exchange: Adversaries may use Windows Dynamic Data Exchange (DDE) to execute arbitrary commands.\n- T1559.001 Component Object Model: Adversaries may use the Windows Component Object Model (COM) for local code execution.\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- **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. […]\n\n## Reference: ATT&CK T1559.001 Component Object Model\n**ATT&CK T1559.001 Component Object Model (full record).** Adversaries may use the Windows Component Object Model (COM) for local code execution. COM is an inter-process communication (IPC) component of the native Windows application programming interface (API) that enables interaction between software objects, or executable code that implements one or more interfaces. Through COM, a client object can call methods of server objects, which are typically binary Dynamic Link Libraries (DLL) or executables (EXE). Remote COM execution is facilitated by Remote Services such as Distributed Component Object Model (DCOM).\n\nVarious COM interfaces are exposed that can be abused to invoke arbitrary execution via a variety of programming languages such as C, C++, Java, and Visual Basic. Specific COM objects also exist to directly perform functions beyond code execution, such as creating a Scheduled Task/Job, fileless download/execution, and other adversary behaviors related to privilege escalation and persistence.\n\n**Classification.** - Tactics: execution\n- Platforms: Windows\n- Sub-technique of: T1559 Inter-Process Communication - Adversaries may abuse inter-process communication (IPC) mechanisms for local code or command execution. IPC is typically used by processes to share data, communicate with each other, or synchronize execution.\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- **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. […]\n\n## Reference: ATT&CK T1559.002 Dynamic Data Exchange\n**ATT&CK T1559.002 Dynamic Data Exchange (full record).** Adversaries may use Windows Dynamic Data Exchange (DDE) to execute arbitrary commands. 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. DDE execution can be invoked remotely via Remote Services such as Distributed Component Object Model (DCOM).\n\n**Classification.** - Tactics: execution\n- Platforms: Windows\n- Sub-technique of: T1559 Inter-Process Communication - Adversaries may abuse inter-process communication (IPC) mechanisms for local code or command execution. IPC is typically used by processes to share data, communicate with each other, or synchronize execution.\n\n**Mitigations.** - **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. […]\n\n## Reference: ATT&CK T1559.003 XPC Services\n**ATT&CK T1559.003 XPC Services (full record).** Adversaries can provide malicious content to an XPC service daemon for local code execution. macOS uses XPC services for basic inter-process communication between various processes, such as between the XPC Service daemon and third-party application privileged helper tools. 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. Requests for malicious execution can be passed through the application's XPC Services handler. This may also include identifying and abusing improper XPC client validation and/or poor sanitization of input parameters to conduct Exploitation for Privilege Escalation.\n\n**Classification.** - Tactics: execution\n- Platforms: macOS\n- Sub-technique of: T1559 Inter-Process Communication - Adversaries may abuse inter-process communication (IPC) mechanisms for local code or command execution. IPC is typically used by processes to share data, communicate with each other, or synchronize execution.\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.** - **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.

[…]\n\n## Reference: ATT&CK T1622 Debugger Evasion\n**ATT&CK T1622 Debugger Evasion (full record).** Adversaries may employ various means to detect and avoid debuggers. Debuggers are typically used by defenders to trace and/or analyze the execution of potential malware payloads.\n\nDebugger evasion may include changing behaviors based on the results of the checks for the presence of artifacts indicative of a debugged environment. Similar to Virtualization/Sandbox Evasion, if the adversary detects a debugger, they may alter their malware to disengage from the victim or conceal the core functions of the implant. They may also search for debugger artifacts before dropping secondary or additional payloads.\n\nSpecific checks will vary based on the target and/or adversary. On Windows, this may involve Native API function calls such as `IsDebuggerPresent` and ` NtQueryInformationProcess`, or manually checking the `BeingDebugged` flag of the Process Environment Block (PEB). On Linux, this may involve querying `/proc/self/status` for the `TracerPID` field, which indicates whether or not the process is being traced by dynamic analysis tools. Other checks for debugging artifacts may also seek to enumerate hardware breakpoints, interrupt assembly opcodes, time checks, or measurements if exceptions are raised in the current process (assuming a present debugger would “swallow” or handle the potential error).\n\nMalware may also leverage Structured Exception Handling (SEH) to detect debuggers by throwing an exception and detecting whether the process is suspended. SEH handles both hardware and software expectations, providing control over the exceptions including support for debugging. If a debugger is present, the program’s control will be transferred to the debugger, and the execution of the code will be suspended. If the debugger is not present, control will be transferred to the SEH handler, which will automatically handle the exception and allow the program’s execution to continue.\n\nAdversaries may use the information learned from these debugger checks during automated discovery to shape follow-on behaviors. Debuggers can also be evaded by detaching the process or flooding debug logs with meaningless data via messages produced by looping Native API function calls such as `OutputDebugStringW`. […]\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. These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms. Most systems come with some built-in command-line interface and scripting capabilities, for example, Android is a UNIX-like OS and includes a basic Unix Shell that can be accessed via the Android Debug Bridge (ADB) or Java’s `Runtime` package.\n\nAdversaries may abuse these technologies in various ways as a means of executing arbitrary commands.

Unix shells are the underlying command prompts on Android and iOS devices. 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. This dangerous level of permissions allows the adversary to run special commands and modify protected system files.\n\n**Classification.** - Tactics: execution\n- Platforms: Android, iOS\n- Sub-technique of: T1623 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

Network sniffing refers to using the network interface on a system to monitor or capture information sent over a wired or wireless connection. An adversary may place a network interface into promiscuous mode to passively access data in transit over the network, or use span ports to capture a larger amount of data.\n\nData captured via this technique may include user credentials, especially those sent over an insecure, unencrypted protocol. Techniques for name service resolution poisoning, such as Name Resolution Poisoning and SMB Relay, can also be used to capture credentials to websites, proxies, and internal systems by redirecting traffic to an adversary.\n\nNetwork sniffing may reveal configuration details, such as running services, version numbers, and other network characteristics (e.g. IP addresses, hostnames, VLAN IDs) necessary for subsequent Lateral Movement and/or Stealth activities. Adversaries may likely also utilize network sniffing during Adversary-in-the-Middle (AiTM) to passively gain additional knowledge about the environment.\n\nIn cloud-based environments, adversaries may still be able to use traffic mirroring services to sniff network traffic from virtual machines. 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. Often, much of this traffic will be in cleartext due to the use of TLS termination at the load balancer level to reduce the strain of encrypting and decrypting traffic. The adversary can then use exfiltration techniques such as Transfer Data to Cloud Account in order to access the sniffed traffic.\n\nOn network devices, adversaries may perform network captures using Network Device CLI commands such as `monitor capture`.\n\n**Classification.** - Tactics: credential-access, discovery\n- Platforms: IaaS, Linux, macOS, Network Devices, 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.

Common methods to acquire this information include port, vulnerability, and/or wordlist scans using tools that are brought onto a system.\n\nWithin cloud environments, adversaries may attempt to discover services running on other cloud hosts. Additionally, if the cloud environment is connected to a on-premises environment, adversaries may be able to identify services running on non-cloud systems as well.\n\nWithin macOS environments, adversaries may use the native Bonjour application to discover services running on other macOS hosts within a network. The Bonjour mDNSResponder daemon automatically registers and advertises a host’s registered services on the network. For example, adversaries can use a mDNS query (such as `dns-sd -B _ssh._tcp.`) to find other systems broadcasting the ssh service.\n\n**Classification.** - Tactics: discovery\n- Platforms: Containers, IaaS, Linux, macOS, Network Devices, 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- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\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\n**Detection strategies and analytics.** - **Behavioral Detection Strategy for Network Service Discovery Across Platforms**\n  - Detects processes performing network enumeration (e.g., port scans, service probing) by correlating process creation, socket connections, and sequential destination IP probing within a time window. […]\n\n## Reference: ATT&CK T1047 Windows Management Instrumentation\n**ATT&CK T1047 Windows Management Instrumentation (full record).** Adversaries may abuse Windows Management Instrumentation (WMI) to execute malicious commands and payloads. WMI is designed for programmers and is the infrastructure for management data and operations on Windows systems. WMI is an administration feature that provides a uniform environment to access Windows system components.\n\nThe WMI service enables both local and remote access, though the latter is facilitated by Remote Services such as Distributed Component Object Model and Windows Remote Management. Remote WMI over DCOM operates using port 135, whereas WMI over WinRM operates over port 5985 when using HTTP and 5986 for HTTPS.\n\nAn adversary can use WMI to interact with local and remote systems and use it as a means to execute various behaviors, such as gathering information for Discovery as well as Execution of commands and payloads. For example, `wmic.exe` can be abused by an adversary to delete shadow copies with the command `wmic.exe Shadowcopy Delete` (i.e., Inhibit System Recovery).\n\n**Note:** `wmic.exe` is deprecated as of January of 2024, with the WMIC feature being “disabled by default” on Windows 11+. WMIC will be removed from subsequent Windows releases and replaced by PowerShell as the primary WMI interface. In addition to PowerShell and tools like `wbemtool.exe`, COM APIs can also be used to programmatically interact with WMI via C++,.NET, VBScript, etc.\n\n**Classification.** - Tactics: execution\n- Platforms: Windows\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- **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.

Often, these devices are equipped with special, dedicated encryption hardware to greatly increase the speed of the encryption process as well as to prevent malicious tampering. When an adversary takes control of such a device, they may disable the dedicated hardware, for example, through use of Modify System Image, forcing the use of software to perform encryption on general processors. This is typically used in conjunction with attacks to weaken the strength of the cipher in software (e.g., Reduce Key Space).\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n- Sub-technique of: T1600 Weaken Encryption - Adversaries may compromise a network device’s encryption capability in order to bypass encryption that would otherwise protect data communications.\n\n**Detection strategies and analytics.** - **Detection Strategy for Weaken Encryption: Disable Crypto Hardware on Network Devices**\n  - Defenders may observe attempts to disable dedicated crypto hardware on network devices, often visible through anomalous CLI commands, unexpected firmware or configuration updates, and degraded encryption performance.

These factors typically include:\n- **Password Policies**: Set 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- **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. 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.

[…]\n\n## Reference: ATT&CK T1020.001 Traffic Duplication\n**ATT&CK T1020.001 Traffic Duplication (full record).** Adversaries may leverage traffic mirroring in order to automate data exfiltration over compromised infrastructure. 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. Encryption ensures the confidentiality and integrity of data, preventing unauthorized access or tampering. 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- **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. […]\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).

[…]\n\n## Reference: ATT&CK T1021.001 Remote Desktop Protocol\n**ATT&CK T1021.001 Remote Desktop Protocol (full record).** Adversaries may use Valid Accounts to log into a computer using the Remote Desktop Protocol (RDP). The adversary may then perform actions as the logged-on user.\n\nRemote 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 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 adversary may then perform actions as the logged-on user.\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- **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- **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.

Reflective loading involves allocating then executing payloads directly within the memory of the process, vice creating a thread or process backed by a file path on disk (e.g., Shared Modules).\n\nReflectively loaded payloads may be compiled binaries, anonymous files (only present in RAM), or just snubs of fileless executable code (ex: position-independent shellcode). For example, the `Assembly.Load` method executed by PowerShell may be abused to load raw code into the running process.\n\nReflective code injection is very similar to Process Injection except that the “injection” loads code into the processes’ own memory instead of that of a separate process. Reflective loading may evade process-based detections since the execution of the arbitrary code may be masked within a legitimate or otherwise benign process. Reflectively loading payloads directly into memory may also avoid creating files or other artifacts on disk, while also enabling malware to keep these payloads encrypted (or otherwise obfuscated) until execution.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n\n**Detection strategies and analytics.** - **Detection Strategy for Reflective Code Loading**\n  - Detect anomalous chains of memory allocation and execution inside the same process (e.g., VirtualAlloc → memcpy → VirtualProtect → CreateThread). Unlike process injection, reflective code loading does not perform cross-process memory writes — the suspicious activity occurs entirely within the process’s own PID context. (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=7, etw:Microsoft-Windows-DotNETRuntime:AssemblyLoad/ModuleLoad (Loader keyword) from Microsoft-Windows-DotNETRuntime)\n  - Monitor for in-process mmap + mprotect + execve/execveat activity where memory permissions are changed from writable to executable inside the same process without a corresponding ELF on disk. […]\n\n## Reference: ATT&CK T1621 Multi-Factor Authentication Request Generation\n**ATT&CK T1621 Multi-Factor Authentication Request Generation (full record).** Adversaries may attempt to bypass multi-factor authentication (MFA) mechanisms and gain access to accounts by generating MFA requests sent to users.\n\nAdversaries in possession of credentials to Valid Accounts may be unable to complete the login process if they lack access to the 2FA or MFA mechanisms required as an additional credential and security control. To circumvent this, adversaries may abuse the automatic generation of push notifications to MFA services such as Duo Push, Microsoft Authenticator, Okta, or similar services to have the user grant access to their account. If adversaries lack credentials to victim accounts, they may also abuse automatic push notification generation when this option is configured for self-service password reset (SSPR).\n\nIn some cases, adversaries may continuously repeat login attempts in order to bombard users with MFA push notifications, SMS messages, and phone calls, potentially resulting in the user finally accepting the authentication request in response to “MFA fatigue.”\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows, Linux, macOS, IaaS, SaaS, Office Suite, Identity Provider\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- **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- **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 T1622 Debugger Evasion\n**ATT&CK T1622 Debugger Evasion (full record).** Adversaries may employ various means to detect and avoid debuggers. Debuggers are typically used by defenders to trace and/or analyze the execution of potential malware payloads.\n\nDebugger evasion may include changing behaviors based on the results of the checks for the presence of artifacts indicative of a debugged environment. Similar to Virtualization/Sandbox Evasion, if the adversary detects a debugger, they may alter their malware to disengage from the victim or conceal the core functions of the implant. They may also search for debugger artifacts before dropping secondary or additional payloads.\n\nSpecific checks will vary based on the target and/or adversary. On Windows, this may involve Native API function calls such as `IsDebuggerPresent` and ` NtQueryInformationProcess`, or manually checking the `BeingDebugged` flag of the Process Environment Block (PEB). On Linux, this may involve querying `/proc/self/status` for the `TracerPID` field, which indicates whether or not the process is being traced by dynamic analysis tools. Other checks for debugging artifacts may also seek to enumerate hardware breakpoints, interrupt assembly opcodes, time checks, or measurements if exceptions are raised in the current process (assuming a present debugger would “swallow” or handle the potential error).\n\nMalware may also leverage Structured Exception Handling (SEH) to detect debuggers by throwing an exception and detecting whether the process is suspended. SEH handles both hardware and software expectations, providing control over the exceptions including support for debugging. If a debugger is present, the program’s control will be transferred to the debugger, and the execution of the code will be suspended. If the debugger is not present, control will be transferred to the SEH handler, which will automatically handle the exception and allow the program’s execution to continue.\n\nAdversaries may use the information learned from these debugger checks during automated discovery to shape follow-on behaviors. Debuggers can also be evaded by detaching the process or flooding debug logs with meaningless data via messages produced by looping Native API function calls such as `OutputDebugStringW`. […]\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. These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms. Most systems come with some built-in command-line interface and scripting capabilities, for example, Android is a UNIX-like OS and includes a basic Unix Shell that can be accessed via the Android Debug Bridge (ADB) or Java’s `Runtime` package.\n\nAdversaries may abuse these technologies in various ways as a means of executing arbitrary commands. Commands and scripts can be embedded in Initial Access payloads delivered to victims as lure documents or as secondary payloads downloaded from an existing C2. Adversaries may also execute commands through interactive terminals/shells.\n\n**Classification.** - Tactics: execution\n- Platforms: Android, iOS\n\n**Sub-techniques.** - T1623.001 Unix Shell: Adversaries may abuse Unix shell commands and scripts for execution. Unix shells are the underlying command prompts on Android and iOS devices.\n\n**Mitigations.** - **Deploy Compromised Device Detection Method**: A variety of methods exist that can be used to enable enterprises to identify compromised (e.g. rooted/jailbroken) devices, whether using security mechanisms built directly into the device, third-party mobile security applications, enterprise mobility management (EMM)/mobile device management (MDM) capabilities, or other methods. Some methods may be trivial to evade while others may be more sophisticated.\n- **Attestation**: Enable remote attestation capabilities when available (such as Android SafetyNet or Samsung Knox TIMA Attestation) and prohibit devices that fail the attestation from accessing enterprise resources.\n\n**Detection strategies and analytics.** - **Detection of Command and Scripting Interpreter**\n  - For Android, detect Command and Scripting Interpreter from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

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. […]\n\n## Reference: ATT&CK T1134.003 Make and Impersonate Token\n**ATT&CK T1134.003 Make and Impersonate Token (full record).** Adversaries may make new tokens and impersonate users to escalate privileges 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.

[…]\n\n## Reference: ATT&CK T1134.004 Parent PID Spoofing\n**ATT&CK T1134.004 Parent PID Spoofing (full record).** Adversaries may spoof the parent process identifier (PPID) of a new process to evade process-monitoring defenses or to elevate privileges. New processes are typically spawned directly from their parent, or calling, process unless explicitly specified. One way of explicitly assigning the PPID of a new process is via the `CreateProcess` API call, which supports a parameter that defines the PPID to use. This functionality is used by Windows features such as User Account Control (UAC) to correctly set the PPID after a requested elevated process is spawned by SYSTEM (typically via `svchost.exe` or `consent.exe`) rather than the current user context.\n\nAdversaries may abuse these mechanisms to evade defenses, such as those blocking processes spawning directly from Office documents, and analysis targeting unusual/potentially malicious parent-child process relationships, such as spoofing the PPID of PowerShell/Rundll32 to be `explorer.exe` rather than an Office document delivered as part of Spearphishing Attachment. This spoofing could be executed via Visual Basic within a malicious Office document or any code that can perform Native API.\n\nExplicitly assigning the PPID may also enable elevated privileges given appropriate access rights to the parent process. For example, an adversary in a privileged user context (i.e. administrator) may spawn a new process and assign the parent as a process running as SYSTEM (such as `lsass.exe`), causing the new process to be elevated via the inherited access token.\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.

[…]\n\n## Reference: ATT&CK T1134.005 SID-History Injection\n**ATT&CK T1134.005 SID-History Injection (full record).** Adversaries may use SID-History Injection to escalate privileges 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.

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\n**Detection strategies and analytics.** - **Behavior-chain detection for T1134.005 Access Token Manipulation: SID-History Injection (Windows)**\n  - Detection of unauthorized modification of Active Directory SID-History attributes to escalate privileges.

Such web services can be abused during later stages of the adversary lifecycle, such as during Command and Control (Web Service), Exfiltration Over Web Service, or Phishing. Using common services, such as those offered by Google or Twitter, makes it easier for adversaries to hide in expected noise. By utilizing a web service, particularly when access is stolen from legitimate users, adversaries can make it difficult to physically tie back operations to them.

This development could be applied to social media, website, or other publicly available information that could be referenced and scrutinized for legitimacy over the course of an operation using that persona or identity.\n\nFor operations incorporating social engineering, the utilization of an online persona may be important. These personas may be fictitious or impersonate real people. The persona may exist on a single site or across multiple sites (ex: Facebook, LinkedIn, Twitter, Google, GitHub, Docker Hub, etc.). Establishing a persona may require development of additional documentation to make them seem real. This could include filling out profile information, developing social networks, or incorporating photos.\n\nEstablishing accounts can also include the creation of accounts with email providers, which may be directly leveraged for Phishing for Information or Phishing.

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. […]\n\n## Reference: ATT&CK T1564.005 Hidden File System\n**ATT&CK T1564.005 Hidden File System (full record).** Adversaries may use a hidden file system to conceal malicious activity from users and security tools. File systems provide a structure to store and access data from physical storage. Typically, a user engages with a file system through applications that allow them to access files and directories, which are an abstraction from their physical location (ex: disk sector). Standard file systems include FAT, NTFS, ext4, and APFS. File systems can also contain other structures, such as the Volume Boot Record (VBR) and Master File Table (MFT) in NTFS.\n\nAdversaries may use their own abstracted file system, separate from the standard file system present on the infected system. In doing so, adversaries can hide the presence of malicious components and file input/output from security tools. Hidden file systems, sometimes referred to as virtual file systems, can be implemented in numerous ways. One implementation would be to store a file system in reserved disk space unused by disk structures or standard file system partitions. Another implementation could be for an adversary to drop their own portable partition image as a file on top of the standard file system. Adversaries may also fragment files across the existing file system structure in non-standard ways.\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**Detection strategies and analytics.** - **Detection Strategy for Hidden File System Abuse**\n  - Anomalous creation or mounting of hidden partitions or virtual file systems. Defender view: detection of registry modifications linked to non-standard file systems, suspicious disk I/O patterns, or bootkit-like behavior where hidden volumes are accessed outside normal file system APIs. […]\n\n## Reference: ATT&CK T1564.006 Run Virtual Instance\n**ATT&CK T1564.006 Run Virtual Instance (full record).** Adversaries may carry out malicious operations using a virtual instance to avoid 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. […]\n\n## Reference: ATT&CK T1564.007 VBA Stomping\n**ATT&CK T1564.007 VBA Stomping (full record).** Adversaries may hide malicious Visual Basic for Applications (VBA) payloads embedded within MS Office documents by replacing the VBA source code with benign data.\n\nMS Office documents with embedded VBA content store source code inside of module streams. 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. 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.** - **Detection Strategy for VBA Stomping**\n  - Discrepancies between VBA source code and p-code inside Office documents.

System administrators can attempt to prevent such attacks using intrusion detection tools and systems. There are many commercially available signature-based Intrusion Detection Systems (IDSs). However, most IDSs lack the capability to detect novel or previously unknown attacks. A special type of IDSs, called Anomaly Detection Systems, develop models based on normal system or network behavior, with the goal of detecting both known and unknown attacks. Anomaly detection systems face many problems including high rate of false alarm, ability to work in online mode, and scalability. This paper presents a selective survey of incremental approaches for detecting anomaly in normal system or network traffic. The technological trends, open problems, and challenges over anomaly detection using incremental approach are also discussed.\n\nClustering.\n\n**1. Introduction.** The Internet connects users and providers of information and media services from distant corners of the world. Due to widespread availability of advanced networking technologies, the threat from spammers, intruders or attackers, and criminal enterprises is also increasing. Intrusion Detection Systems (IDSs) and firewall technologies can prevent some of these threats. One study [1] estimates the number of intrusion attempts over the entire Internet to be in the order of 25 billion per day and increasing. McHugh [2] claims that attacks are becoming more sophisticated while they get more automated, and thus the skills needed to launch them are being reduced. There are two types of IDSs: signature-based and anomaly-based. Signature-based IDSs exploit signatures of known attacks. Such systems require frequent updates of signatures for known attacks and cannot detect unknown attacks or anomalies for which signatures are not stored in the database. In contrast, anomaly based IDSs are extremely effective in finding and preventing known as well as unknown or zero day attacks [3][54]. However, an anomaly detection system has many shortcomings such as high rate of false alarm, and the failure to scale up to gigabit speeds.

Unfortunately, they also become fertile grounds for hackers to deploy malware and to spread virus. There is an urgent need to have a “ security analytic & forensic system ” which can facilitate analysts to examine, dissect, associate and correlate large number of mobile applications. An effective analytic system needs to address the following questions:\n\nHow to automatically collect and manage a high volume of mobile malware? How to analyze a zero-day suspicious application, and compare or associate it with existing malware families in the database? How to perform information retrieval so to reveal similar malicious logic with existing malware, and to quickly identify the new malicious code segment?\n\nIn this paper, we present the design and implementation of\n\nDroidAnalytics, a signature based analytic system to automatically collect, manage, analyze and extract android malware. The system facilitates analysts to retrieve, associate and reveal malicious logics at the “ opcode level ”. We demonstrate the efficacy of DroidAnalytics using 150,368 Android applications, and successfully determine 2,494 Android malware from 102 different families, with 342 of them being zero-day malware samples from six different families. To the best of our knowledge, this is the first reported case in showing such a large Android malware analysis/detection. The evaluation shows the DroidAnalytics is a valuable tool and is effective in analyzing malware repackaging and mutations.\n\nI\n\n**Introduction.** Smartphones are becoming prevailing devices for many people. Unfortunately, malware on smartphones is also increasing at an unprecedented rate. Android OS-based systems, being the most popular platform for mobile devices, have been a popular target for malware developers. As stated in [1], the exponential growth of mobile malware is mainly due to the ease of generating malware variants. Although there are number of works which focus on Android malware detection via permission leakage, it is equally important to design a system that can perform comprehensive malware analytics: analyze and dissect suspicious applications at the opcode level\n\n(instead at the permission level), and correlate these applications to existing malware in the database to determine whether they are mutated malware or even zero-day malware, and to discover which legitimate applications are infected.

IMPLEMENTATION OF DES CRYPTANALYSIS.** The aim of the hardware is the probable key search to be accomplished by partitioning the solution space on the FPGA chip and instantiating multiple instances of the design in parallel. As the solution space is independent and inter-process communication is hardly required, the key search time can be reduced by ‘n’ fold for ‘n’ instances of the design in single a FPGA chip.\n\nWe have implemented the design in Virtex-4 FPGA chip (xc4vlx100-12ff1148) using Xilinx 13.1 development platform. The design is implemented using both Rolled and Unrolled architecture. After synthesis of the design incorporating key search engines in a single FPGA along with the additional logic required for finding the correct key, the device utilization and throughput for both the architectures are as shown below.\n\n13\n\n**6.1. Using Rolled Architecture.** The usage of 1,662 slices, 892 slice flip-flops (FF) and 3,187 Look up Tables (LUTs) is reported by the tool. (3% slices, 0% slice FF and 3% LUT utilization of the xc4vlx100-12ff1148 device respectively). The throughput achieved for the design is 0.817GBPS with maximum frequency of 230.063MHz.\n\n**6.2. Using Unrolled Architecture.** The usage of 9,019 slices, 7,614 slice flip-flops and 16,954 LUTs is reported by the tool. (18% slices, 7% slice FF and 17% LUT utilization of the xc4vlx100-12ff1148 device respectively). The throughput achieved for the design is 0.874GBPS with maximum frequency of 245.874MHz.\n\nFrom the above experimental results, the device utilization for design using Rolled architecture is considerably less as compared to design using Unrolled architecture. Hence the Rolled architecture was selected for implementation. 256 key search instances for the Rolled architecture could be fit in a single FPGA with a clock frequency of 323.515MHz.

Professor/CSE Erode Sengunthar Engineering College, Erode, India 2, 3 B.E. C.S.E. Student, Erode Sengunthar Engineering College, Erode, India Email:saravanankumarasamy@gmail.com\n\n**ABSTRACT.** Mobile ad-hoc networks are temporary wireless networks. Network resources are abnormally consumed by intruders. Anomaly and signature based techniques are used for intrusion detection. Classification techniques are used in anomaly based techniques. Intrusion detection techniques are used for the network attack detection process. Two types of intrusion detection systems are available. They are anomaly detection and signature based detection model. The anomaly detection model uses the historical transactions with attack labels. The signature database is used in the signature based IDS schemes.\n\nThe mobile ad-hoc networks are infrastructure less environment. The intrusion detection applications are placed in a set of nodes under the mobile ad-hoc network environment. The nodes are grouped into clusters. The leader nodes are assigned for the clusters. The leader node is assigned for the intrusion detection process. Leader nodes are used to initiate the intrusion detection process. Resource sharing and lifetime management factors are considered in the leader election process. The system optimizes the leader election and intrusion detection process.\n\nThe system is designed to handle leader election and intrusion detection process. The clustering scheme is optimized with coverage and traffic level. Cost and resource utilization is controlled under the clusters. Node mobility is managed by the system.\n\n**1. INTRODUCTION.** Unlike traditional networks, the Mobile Ad hoc Networks (MANETs) have no fixed chokepoints/bottlenecks where Intrusion Detection Systems (IDSs) can be deployed [3]. Hence, a node may need to run its own IDS [1] and cooperate with others to ensure security. This is very inefficient in terms of resource consumption since mobile nodes are energylimited. […]"}]}

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.

[…]\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.

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.

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. Most modern systems contain native elevation control mechanisms that are intended to limit privileges that a user can perform on a machine. […]\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.

The PEB includes the process command-line arguments that are referenced when executing the process. When a process is created, defensive tools/sensors that monitor process creations may retrieve the process arguments from the PEB.\n\nAdversaries may manipulate a process PEB to evade defenses. For example, Process Hollowing can be abused to spawn a process in a suspended state with benign arguments. After the process is spawned and the PEB is initialized (and process information is potentially logged by tools/sensors), adversaries may override the PEB to modify the command-line arguments (ex: using the Native API `WriteProcessMemory` function) then resume process execution with malicious arguments.\n\nAdversaries may also execute a process with malicious command-line arguments then patch the memory with benign arguments that may bypass subsequent process memory analysis.\n\nThis behavior may also be combined with other tricks (such as Parent PID Spoofing) to manipulate or further evade process-based detections.\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**Detection strategies and analytics.** - **Detection Strategy for Process Argument Spoofing on Windows**\n  - Inconsistencies between process command-line arguments logged at creation time and subsequent process behavior. Defender perspective: monitoring for processes launched in a suspended state, followed by memory modifications (e.g., WriteProcessMemory targeting the PEB) that overwrite arguments before execution resumes.

Many operating systems use signals to deliver messages to control process behavior. Command interpreters often include specific commands/flags that ignore errors and other hangups, such as when the user of the active session logs off. These interrupt signals may also be used by defensive tools and/or analysts to pause or terminate specified running processes.\n\nAdversaries may invoke processes using `nohup`, PowerShell `-ErrorAction SilentlyContinue`, or similar commands that may be immune to hangups. This may enable malicious commands and malware to continue execution through system events that would otherwise terminate its execution, such as users logging off or the termination of its C2 network connection.\n\nHiding from process interrupt signals may allow malware to continue execution, but unlike Trap this does not establish Persistence since the process will not be re-invoked once actually terminated.\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**Detection strategies and analytics.** - **Detection Strategy for Ignore Process Interrupts**\n  - Execution of processes using nohup or shell redirection to ignore SIGHUP and continue running after session termination.

AV and other file-based scanners often include exclusions to optimize performance as well as ease installation and legitimate use of applications. These exclusions may be contextual (e.g., scans are only initiated in response to specific triggering events/alerts), but are also often hardcoded strings referencing specific folders and/or files assumed to be trusted and legitimate.\n\nAdversaries may abuse these exclusions to hide their file-based artifacts. For example, rather than tampering with tool settings to add a new exclusion (i.e., Disable or Modify Tools), adversaries may drop their file-based payloads in default or otherwise well-known exclusions. Adversaries may also use Security Software Discovery and other Discovery/Reconnaissance activities to both discover and verify existing exclusions in a victim environment.\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.** - **Antivirus/Antimalware**: Antivirus/Antimalware solutions utilize signatures, heuristics, and behavioral analysis to detect, block, and remediate malicious software, including viruses, trojans, ransomware, and spyware.

Antivirus/Antimalware software should be deployed across all devices, with automated updates to ensure protection against the latest threats.\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.

A bind mount maps a directory or file from one location on the filesystem to another, similar to a shortcut on Windows. It’s commonly used to provide access to specific files or directories across different environments, such as inside containers or chroot environments, and requires sudo access.\n\nAdversaries may use bind mounts to map either an empty directory or a benign `/proc` directory to a malicious process’s `/proc` directory. Using the commands `mount –o bind /proc/benign-process /proc/malicious-process` (or `mount –B`), the malicious process's `/proc` directory is overlayed with the contents of a benign process's `/proc` directory. When system utilities query process activity, such as `ps` and `top`, the kernel follows the bind mount and presents the benign directory’s contents instead of the malicious process's actual `/proc` directory. As a result, these utilities display information that appears to come from the benign process, effectively hiding the malicious process's metadata, executable, or other artifacts from detection.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.\n\n**Detection strategies and analytics.** - **Detection Strategy for Bind Mounts on Linux**\n  - Abuse of bind mounts to obscure process directories. Defender perspective: detecting anomalous mount operations where a process’s /proc entry is remapped to another directory, often hiding malicious activity from native utilities (ps, top).

ATT&CK analytics reference these components.\n\n## Reference: ATT&CK T1497.001 System Checks\n**ATT&CK T1497.001 System Checks (full record).** Adversaries may employ various system checks to detect and avoid virtualization and analysis environments. This may include changing behaviors based on the results of checks for the presence of artifacts indicative of a virtual machine environment (VME) or sandbox. If the adversary detects a VME, they may alter their malware to disengage from the victim or conceal the core functions of the implant. They may also search for VME artifacts before dropping secondary or additional payloads. Adversaries may use the information learned from Virtualization/Sandbox Evasion during automated discovery to shape follow-on behaviors.\n\nSpecific checks will vary based on the target and/or adversary, but may involve behaviors such as Windows Management Instrumentation, PowerShell, System Information Discovery, and Query Registry to obtain system information and search for VME artifacts. Adversaries may search for VME artifacts in memory, processes, file system, hardware, and/or the Registry. Adversaries may use scripting to automate these checks into one script and then have the program exit if it determines the system to be a virtual environment.\n\nChecks could include generic system properties such as host/domain name and samples of network traffic. Adversaries may also check the network adapters addresses, CPU core count, and available memory/drive size. Once executed, malware may also use File and Directory Discovery to check if it was saved in a folder or file with unexpected or even analysis-related naming artifacts such as `malware`, `sample`, or `hash`.\n\nOther common checks may enumerate services running that are unique to these applications, installed programs on the system, manufacturer/product fields for strings relating to virtual machine applications, and VME-specific hardware/processor instructions. In applications like VMWare, adversaries can also use a special I/O port to send commands and receive output.\n\nHardware checks, such as the presence of the fan, temperature, and audio devices, could also be used to gather evidence that can be indicative a virtual environment. Adversaries may also query for specific readings from these devices.

If the adversary detects a VME, they may alter their malware to disengage from the victim or conceal the core functions of the implant. They may also search for VME artifacts before dropping secondary or additional payloads. Adversaries may use the information learned from Virtualization/Sandbox Evasion during automated discovery to shape follow-on behaviors.\n\nAdversaries may search for user activity on the host based on variables such as the speed/frequency of mouse movements and clicks, browser history, cache, bookmarks, or number of files in common directories such as home or the desktop. Other methods may rely on specific user interaction with the system before the malicious code is activated, such as waiting for a document to close before activating a macro or waiting for a user to double click on an embedded image to activate.\n\n**Classification.** - Tactics: stealth, discovery\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1497 Virtualization/Sandbox Evasion - Adversaries may employ various means to detect and avoid virtualization and analysis environments.

By manipulating transmitted data, adversaries may attempt to affect a business process, organizational understanding, or decision making.\n\nManipulation may be possible over a network connection or between system processes where there is an opportunity to deploy a tool that will intercept and change information. The type of modification and the impact it will have depends on the target transmission mechanism as well as the goals and objectives of the adversary. For complex systems, an adversary would likely need special expertise and possibly access to specialized software related to the system, typically gained through a prolonged information gathering campaign, in order to have the desired impact.\n\nOne method to achieve Transmitted Data Manipulation is by modifying the contents of the device clipboard. Malicious applications may monitor clipboard activity through the `ClipboardManager.OnPrimaryClipChangedListener` interface on Android to determine when clipboard contents have changed. Listening to clipboard activity, reading clipboard contents, and modifying clipboard contents requires no explicit application permissions and can be performed by applications running in the background. However, this behavior has changed with the release of Android 10.\n\nAdversaries may use Transmitted Data Manipulation to replace text prior to being pasted. For example, replacing a copied Bitcoin wallet address with a wallet address that is under adversarial control.\n\nTransmitted Data Manipulation was seen within the Android/Clipper.C trojan. This sample was detected by ESET in an application distributed through the Google Play Store targeting cryptocurrency wallet numbers.\n\n**Classification.** - Tactics: impact\n- Platforms: Android\n- Sub-technique of: T1641 Data Manipulation - Adversaries may insert, delete, or alter data in order to manipulate external outcomes or hide activity. By manipulating data, adversaries may attempt to affect a business process, organizational understanding, or decision making.\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. […]\n\n## Reference: ATT&CK T1642 Endpoint Denial of Service\n**ATT&CK T1642 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.\n\nOn Android versions prior to 7, apps can abuse Device Administrator access to reset the device lock passcode, preventing the user from unlocking the device. After Android 7, only device or profile owners (e.g. MDMs) can reset the device’s passcode.\n\nOn iOS devices, this technique does not work because mobile device management servers can only remove the screen lock passcode; they cannot set a new passcode. However, on jailbroken devices, malware has been discovered that can lock the user out of the device.\n\n**Classification.** - Tactics: impact\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.

[…]\n\n## Reference: ATT&CK T1643 Generate Traffic from Victim\n**ATT&CK T1643 Generate Traffic from Victim (full record).** Adversaries may generate outbound traffic from devices. This is typically performed to manipulate external outcomes, such as to achieve carrier billing fraud or to manipulate app store rankings or ratings. Outbound traffic is typically generated as SMS messages or general web traffic, but may take other forms as well.\n\nIf done via SMS messages, Android apps must hold the `SEND_SMS` permission. Additionally, sending an SMS message requires user consent if the recipient is a premium number.

This could be done for a variety of reasons, including evading network traffic monitoring, as a backup method of command and control, or for data exfiltration if the device is not connected to any Internet-providing networks (i.e. cellular or Wi-Fi). Several out of band data streams exist, such as SMS messages, NFC, and Bluetooth.\n\nOn Android, applications can read push notifications to capture content from SMS messages, or other out of band data streams. This requires that the user manually grant notification access to the application via the settings menu. However, the application could launch an Intent to take the user directly there.\n\nOn iOS, there is no way to programmatically read push notifications.\n\n**Classification.** - Tactics: command-and-control\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 Out of Band Data**\n  - For Android, detect Out of Band Data by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

System software binaries are used by the underlying operating system and users over adb or terminal emulators.\n\nAdversaries may make modifications to client software binaries to carry out malicious tasks when those binaries are executed. For example, malware may come with a pre-compiled malicious binary intended to overwrite the genuine one on the device. Since these binaries may be routinely executed by the system or user, the adversary can leverage this for persistent access to the device.\n\n**Classification.** - Tactics: persistence\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- **System Partition Integrity**: Ensure that Android devices being used include and enable the Verified Boot capability, which cryptographically ensures the integrity of the system partition.\n- **Security Updates**: Install security updates in response to discovered vulnerabilities.\n- **Attestation**: Enable remote attestation capabilities when available (such as Android SafetyNet or Samsung Knox TIMA Attestation) and prohibit devices that fail the attestation from accessing enterprise resources.\n\n**Detection strategies and analytics.** - **Detection of Compromise Client Software Binary**\n  - For Android, detect Compromise Client Software Binary from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private that should not be distributed. Due to how asymmetric algorithms work, 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, ElGamal, and ECDSA.\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: 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**Detection strategies and analytics.** - **Detection of Asymmetric Cryptography**\n  - For Android, detect Asymmetric Cryptography from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events. […]\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.

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.

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.

Customers may request adjustments to these quotas to support increased computing needs, though these adjustments may require approval from the cloud provider. Adversaries who compromise a cloud environment may similarly request quota adjustments in order to support their activities, such as enabling additional Resource Hijacking without raising suspicion by using up a victim’s entire quota.

This includes compute service resources such as instances, virtual machines, and snapshots as well as resources of other services including the storage and database services.\n\nCloud providers offer methods such as APIs and commands issued through CLIs to serve information about infrastructure. For example, AWS provides a `DescribeInstances` API within the Amazon EC2 API that can return information about one or more instances within an account, the `ListBuckets` API that returns a list of all buckets owned by the authenticated sender of the request, the `HeadBucket` API to determine a bucket’s existence along with access permissions of the request sender, or the `GetPublicAccessBlock` API to retrieve access block configuration for a bucket. Similarly, GCP's Cloud SDK CLI provides the `gcloud compute instances list` command to list all Google Compute Engine instances in a project, and Azure's CLI command `az vm list` lists details of virtual machines. In addition to API commands, adversaries can utilize open source tools to discover cloud storage infrastructure through Wordlist Scanning.\n\nAn adversary may enumerate resources using a compromised user's access keys to determine which are available to that user. The discovery of these available resources may help adversaries determine their next steps in the Cloud environment, such as establishing Persistence.An adversary may also use this information to change the configuration to make the bucket publicly accessible, allowing data to be accessed without authentication. Adversaries have also may use infrastructure discovery APIs such as `DescribeDBInstances` to determine size, owner, permissions, and network ACLs of database resources. Adversaries can use this information to determine the potential value of databases and discover the requirements to access them.

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.

Network DoS can be performed by exhausting the network bandwidth that services rely on, or by jamming the signal going to or coming from devices.\n\nA Network DoS will occur when an adversary is able to jam radio signals (e.g. Wi-Fi, cellular, GPS) around a device to prevent it from communicating. For example, to jam cellular signal, an adversary may use a handheld signal jammer, which jam devices within the jammer’s operational range.\n\nUsage of cellular jamming has been documented in several arrests reported in the news.\n\n**Classification.** - Tactics: impact\n- Platforms: Android, iOS\n\n**Detection strategies and analytics.** - **Detection of Network Denial of Service**\n  - For Android, detect Network Denial of Service by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

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.

Password managers are applications designed to store user credentials, normally in an encrypted database. Credentials are typically accessible after a user provides a master password that unlocks the database. After the database is unlocked, these credentials may be copied to memory. These databases can be stored as files on disk.\n\nAdversaries may acquire user credentials from password managers by extracting the master password and/or plain-text credentials from memory. Adversaries may extract credentials from memory via Exploitation for Credential Access.\nAdversaries may also try brute forcing via Password Guessing to obtain the master password of a password manager.\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. Passwords are stored in several places on a system, depending on the operating system or application holding the credentials.\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 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- **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 T1555.006 Cloud Secrets Management Stores\n**ATT&CK T1555.006 Cloud Secrets Management Stores (full record).** Adversaries may acquire credentials from cloud-native secret management solutions such as AWS Secrets Manager, GCP Secret Manager, Azure Key Vault, and Terraform Vault.\n\nSecrets managers support the secure centralized management of passwords, API keys, and other credential material. Where secrets managers are in use, cloud services can dynamically acquire credentials via API requests rather than accessing secrets insecurely stored in plain text files or environment variables.\n\nIf an adversary is able to gain sufficient privileges in a cloud environment – for example, by obtaining the credentials of high-privileged Cloud Accounts or compromising a service that has permission to retrieve secrets – they may be able to request secrets from the secrets manager. This can be accomplished via commands such as `get-secret-value` in AWS, `gcloud secrets describe` in GCP, and `az key vault secret show` in Azure.\n\n**Note:** this technique is distinct from Cloud Instance Metadata API in that the credentials are being directly requested from the cloud secrets manager, rather than through the medium of the instance metadata API.\n\n**Classification.** - Tactics: credential-access\n- Platforms: IaaS\n- Sub-technique of: T1555 Credentials from Password Stores - Adversaries may search for common password storage locations to obtain user credentials.

The authentication process is handled by mechanisms, such as the Local Security Authentication Server (LSASS) process and the Security Accounts Manager (SAM) on Windows, pluggable authentication modules (PAM) on Unix-based systems, and authorization plugins on MacOS systems, responsible for gathering, storing, and validating credentials. By modifying an authentication process, an adversary may be able to authenticate to a service or system without using Valid Accounts.\n\nAdversaries may maliciously modify a part of this process to either reveal credentials or bypass authentication mechanisms. Compromised credentials or access 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 and remote desktop.\n\n**Classification.** - Tactics: defense-impairment, persistence, credential-access\n- Platforms: IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1556.004 Network Device Authentication: Adversaries may use Patch System Image to hard code a password in the operating system, thus bypassing of native authentication mechanisms for local accounts on network devices.\n- T1556.001 Domain Controller Authentication: Adversaries may patch the authentication process on a domain controller to bypass the typical authentication mechanisms and enable access to accounts.\n- T1556.009 Conditional Access Policies: Adversaries may disable or modify conditional access policies to enable persistent access to compromised accounts.\n- T1556.008 Network Provider DLL: Adversaries may register malicious network provider dynamic link libraries (DLLs) to capture cleartext user credentials during the authentication process.\n- T1556.002 Password Filter DLL: Adversaries may register malicious password filter dynamic link libraries (DLLs) into the authentication process to acquire user credentials as they are validated.

Skeleton key works through a patch on an enterprise domain controller authentication process (LSASS) with credentials that adversaries may use to bypass the standard authentication system. Once patched, an adversary can use the injected password to successfully authenticate as any domain user account (until the the skeleton key is erased from memory by a reboot of the domain controller). Authenticated access may enable unfettered access to hosts and/or resources within single-factor authentication environments.\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 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- **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- **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.

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. 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\n**Detection strategies and analytics.** - **Detection of Hooking**\n  - Real-time monitoring identifies an unsigned or unexpected process calling Windows hooking Application Programming Interfaces (APIs) (SetWindowsHookEx, SetWinEventHook) targeting an Industrial Control System (ICS) engineering or Human-Machine Interface (HMI) process, immediately followed by that target process loading a Dynamic Link Library (DLL) not present in the vendor's signed module baseline. […]\n\n## Reference: ATT&CK T0877 I/O Image\n**ATT&CK T0877 I/O Image (full record).** Adversaries may seek to capture process values related to the inputs and outputs of a PLC. 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. OT operational-fidelity gate: Do not alert on novelty, scan/read volume, or enumeration alone. […]\n\n## Reference: ATT&CK T0878 Alarm Suppression\n**ATT&CK T0878 Alarm Suppression (full record).** Adversaries may target protection function alarms to prevent them from notifying operators of critical conditions. 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. […]\n\n## Reference: ATT&CK T0879 Damage to Property\n**ATT&CK T0879 Damage to Property (full record).** Adversaries may cause damage and destruction of property to infrastructure, equipment, and the surrounding environment when attacking control systems. 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. Reportedly, four trams were derailed and were forced to make emergency stops. Commands issued by the student may have also resulted in tram collisions, causing harm to those on board and the environment outside.\n\n**Classification.** - Tactics: impact\n- Platforms: None\n\n**Mitigations.** - **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- **Safety Instrumented Systems**: Utilize Safety Instrumented Systems (SIS) to provide an additional layer of protection to hazard scenarios that may cause property damage. […]\n\n## Reference: ATT&CK T0880 Loss of Safety\n**ATT&CK T0880 Loss of Safety (full record).** Adversaries may compromise safety system functions designed to maintain safe operation of a process when unacceptable or dangerous conditions occur. 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. A SIS will typically include sensors, logic solvers, and a final control element that can be used to automatically respond to an hazardous condition. Ensure that all SISs are segmented from operational networks to prevent them from being targeted by additional adversarial behavior.\n- **Mechanical Protection Layers**: Utilize a layered protection design based on physical or mechanical protection systems to prevent damage to property, equipment, human safety, or the environment. Examples include interlocks, rupture disk, release values, etc.\n\n**Detection strategies and analytics.** - **Detection of Loss of Safety**\n  - No standard detection method currently exists for this technique. (telemetry: )\n\n**Tracked users (groups, malware, tools).** - CyberAv3ngers (intrusion-set): The CyberAv3ngers are a suspected Iranian Government Islamic Revolutionary Guard Corps (IRGC)-affiliated APT group.\n- Triton (malware): Triton is an attack framework built to interact with Triconex Safety Instrumented System (SIS) controllers."}]}

Persona development consists of the development of public information, presence, history and appropriate affiliations.\n\nFor operations incorporating social engineering, the utilization of a persona on social media may be important. These personas may be fictitious or impersonate real people. The persona may exist on a single social media site or across multiple sites (ex: Facebook, LinkedIn, Twitter, etc.). Establishing a persona on social media may require development of additional documentation to make them seem real. This could include filling out profile information, developing social networks, or incorporating photos.\n\nOnce a persona has been developed an adversary can use it to create connections to targets of interest. These connections may be direct or may include trying to connect through others. These accounts may be leveraged during other phases of the adversary lifecycle, such as during Initial Access (ex: Spearphishing via Service).\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1585 Establish Accounts - Adversaries may create and cultivate accounts with services that can be used during targeting.

Rather than creating and cultivating accounts (i.e. Establish Accounts), adversaries may compromise existing accounts. Utilizing an existing persona may engender a level of trust in a potential victim if they have a relationship, or knowledge of, the compromised persona.\n\nA variety of methods exist for compromising accounts, such as gathering credentials via Phishing for Information, purchasing credentials from third-party sites, brute forcing credentials (ex: password reuse from breach credential dumps), or paying employees, suppliers or business partners for access to credentials. Prior to compromising accounts, adversaries may conduct Reconnaissance to inform decisions about which accounts to compromise to further their operation.\n\nPersonas may exist on a single site or across multiple sites (ex: Facebook, LinkedIn, Twitter, Google, etc.).

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. […]\n\n## Reference: ATT&CK T1564.005 Hidden File System\n**ATT&CK T1564.005 Hidden File System (full record).** Adversaries may use a hidden file system to conceal malicious activity from users and security tools. File systems provide a structure to store and access data from physical storage. Typically, a user engages with a file system through applications that allow them to access files and directories, which are an abstraction from their physical location (ex: disk sector). Standard file systems include FAT, NTFS, ext4, and APFS. File systems can also contain other structures, such as the Volume Boot Record (VBR) and Master File Table (MFT) in NTFS.\n\nAdversaries may use their own abstracted file system, separate from the standard file system present on the infected system. In doing so, adversaries can hide the presence of malicious components and file input/output from security tools. Hidden file systems, sometimes referred to as virtual file systems, can be implemented in numerous ways. One implementation would be to store a file system in reserved disk space unused by disk structures or standard file system partitions. Another implementation could be for an adversary to drop their own portable partition image as a file on top of the standard file system. Adversaries may also fragment files across the existing file system structure in non-standard ways.\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**Detection strategies and analytics.** - **Detection Strategy for Hidden File System Abuse**\n  - Anomalous creation or mounting of hidden partitions or virtual file systems. Defender view: detection of registry modifications linked to non-standard file systems, suspicious disk I/O patterns, or bootkit-like behavior where hidden volumes are accessed outside normal file system APIs. […]\n\n## Reference: ATT&CK T1564.006 Run Virtual Instance\n**ATT&CK T1564.006 Run Virtual Instance (full record).** Adversaries may carry out malicious operations using a virtual instance to avoid 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. […]\n\n## Reference: ATT&CK T1564.007 VBA Stomping\n**ATT&CK T1564.007 VBA Stomping (full record).** Adversaries may hide malicious Visual Basic for Applications (VBA) payloads embedded within MS Office documents by replacing the VBA source code with benign data.\n\nMS Office documents with embedded VBA content store source code inside of module streams. 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. 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.** - **Detection Strategy for VBA Stomping**\n  - Discrepancies between VBA source code and p-code inside Office documents.

The adversary may then perform actions as the logged-on user.\n\nThe Windows Component Object Model (COM) is a component of the native Windows application programming interface (API) that enables interaction between software objects, or executable code that implements one or more interfaces. Through COM, a client object can call methods of server objects, which are typically Dynamic Link Libraries (DLL) or executables (EXE). 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. DCOM can be used as a method of remotely interacting with Windows Management Instrumentation.\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 adversary may then perform actions as the logged-on user.\n\nSSH is a protocol that allows authorized users to open remote shells on other computers. 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. In this authentication scenario, the user’s public key must be in a special file on the computer running the server that lists which keypairs are allowed to login as that user (i.e., SSH Authorized Keys).\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: ESXi, Linux, macOS, 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 adversary may then perform actions as the logged-on user.\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- **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. […]\n\n## Reference: ATT&CK T1021.005 VNC\n**ATT&CK T1021.005 VNC (full record).** Adversaries may use Valid Accounts to remotely control machines using Virtual Network Computing (VNC). 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.

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- **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- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations.

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- **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- **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\n**Detection strategies and analytics.** - **Behavioral Detection of WinRM-Based Remote Access**\n  - Adversaries using WinRM to remotely execute commands, launch child processes, or access WMI.

Python is a very popular scripting/programming language, with capabilities to perform many functions. Python can be executed interactively from the command-line (via the `python.exe` interpreter) or via scripts (.py) that can be written and distributed to different systems. Python code can also be compiled into binary executables.\n\nPython comes with many built-in packages to interact with the underlying system, such as file operations and device I/O. Adversaries can use these libraries to download and execute commands or other scripts as well as perform various malicious behaviors.\n\n**Classification.** - Tactics: execution\n- Platforms: ESXi, 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. These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms.\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- **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- **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.

JavaScript (JS) is a platform-independent scripting language (compiled just-in-time at runtime) commonly associated with scripts in webpages, though JS can be executed in runtime environments outside the browser.\n\nJScript is the Microsoft implementation of the same scripting standard. JScript is interpreted via the Windows Script engine and thus integrated with many components of Windows such as the Component Object Model and Internet Explorer HTML Application (HTA) pages.\n\nJavaScript for Automation (JXA) is a macOS scripting language based on JavaScript, included as part of Apple’s Open Scripting Architecture (OSA), that was introduced in OSX 10.10. Apple’s OSA provides scripting capabilities to control applications, interface with the operating system, and bridge access into the rest of Apple’s internal APIs. As of OSX 10.10, OSA only supports two languages, JXA and AppleScript. Scripts can be executed via the command line utility `osascript`, they can be compiled into applications or script files via `osacompile`, and they can be compiled and executed in memory of other programs by leveraging the OSAKit Framework.\n\nAdversaries may abuse various implementations of JavaScript to execute various behaviors. Common uses include hosting malicious scripts on websites as part of a Drive-by Compromise or downloading and executing these script files as secondary payloads. Since these payloads are text-based, it is also very common for adversaries to obfuscate their content as part of Obfuscated Files or Information.\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. These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms.\n\n**Mitigations.** - **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 T1059.008 Network Device CLI\n**ATT&CK T1059.008 Network Device CLI (full record).** Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads. The CLI is the primary means through which users and administrators interact with the device in order to view system information, modify device operations, or perform diagnostic and administrative functions. CLIs typically contain various permission levels required for different commands.\n\nScripting interpreters automate tasks and extend functionality beyond the command set included in the network OS. The CLI and scripting interpreter are accessible through a direct console connection, or through remote means, such as telnet or SSH.\n\nAdversaries can use the network CLI to change how network devices behave and operate. The CLI may be used to manipulate traffic flows to intercept or manipulate data, modify startup configuration parameters to load malicious system software, or to disable security features or logging to avoid detection.\n\n**Classification.** - Tactics: execution\n- Platforms: Network Devices\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- **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. […]\n\n## Reference: ATT&CK T1059.009 Cloud API\n**ATT&CK T1059.009 Cloud API (full record).** Adversaries may abuse cloud APIs to execute malicious commands. APIs available in cloud environments provide various functionalities and are a feature-rich method for programmatic access to nearly all aspects of a tenant. These APIs may be utilized through various methods such as command line interpreters (CLIs), in-browser Cloud Shells, PowerShell modules like Azure for PowerShell, or software developer kits (SDKs) available for languages such as Python.\n\nCloud API functionality may allow for administrative access across all major services in a tenant such as compute, storage, identity and access management (IAM), networking, and security policies.\n\nWith proper permissions (often via use of credentials such as Application Access Token and Web Session Cookie), adversaries may abuse cloud APIs to invoke various functions that execute malicious actions. For example, CLI and PowerShell functionality may be accessed through binaries installed on cloud-hosted or on-premises hosts or accessed through a browser-based cloud shell offered by many cloud platforms (such as AWS, Azure, and GCP). These cloud shells are often a packaged unified environment to use CLI and/or scripting modules hosted as a container in the cloud environment.\n\n**Classification.** - Tactics: execution\n- Platforms: IaaS, Identity Provider, Office Suite, SaaS\n- Sub-technique of: T1059 Command and Scripting Interpreter - Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

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.

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. The KRBTGT password hash may be obtained using OS Credential Dumping and privileged access to a domain controller.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows\n- Sub-technique of: T1558 Steal or Forge Kerberos Tickets - Adversaries may attempt to subvert Kerberos authentication by stealing or forging Kerberos tickets to enable Pass the Ticket.

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- **Active Directory Configuration**: 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.

Kerberos TGS tickets are also known as service tickets.\n\nSilver tickets are more limited in scope in than golden tickets in that they only enable adversaries to access a particular resource (e.g. MSSQL) and the system that hosts the resource; however, unlike golden tickets, adversaries with the ability to forge silver tickets are able to create TGS tickets without interacting with the Key Distribution Center (KDC), potentially making detection more difficult.\n\nPassword hashes for target services may be obtained using OS Credential Dumping or Kerberoasting.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows\n- Sub-technique of: T1558 Steal or Forge Kerberos Tickets - Adversaries may attempt to subvert Kerberos authentication by stealing or forging Kerberos tickets to enable Pass the Ticket.

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- **Encrypt Sensitive Information**: Protect sensitive information at rest, in transit, and during processing by using strong encryption algorithms.

To enable authentication, Kerberos requires that SPNs be associated with at least one service logon account (an account specifically tasked with running a service).\n\nAdversaries possessing a valid Kerberos ticket-granting ticket (TGT) may request one or more Kerberos ticket-granting service (TGS) service tickets for any SPN from a domain controller (DC). Portions of these tickets may be encrypted with the RC4 algorithm, meaning the Kerberos 5 TGS-REP etype 23 hash of the service account associated with the SPN is used as the private key and is thus vulnerable to offline Brute Force attacks that may expose plaintext credentials.\n\nThis same behavior could be executed using service tickets captured from network traffic.\n\nCracked hashes may enable Persistence, Privilege Escalation, and Lateral Movement via access to Valid Accounts.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows\n- Sub-technique of: T1558 Steal or Forge Kerberos Tickets - Adversaries may attempt to subvert Kerberos authentication by stealing or forging Kerberos tickets to enable Pass the Ticket.

When enabled, a user requesting access to a resource initiates communication with the Domain Controller (DC) by sending an Authentication Server Request (AS-REQ) message with a timestamp that is encrypted with the hash of their password. If and only if the DC is able to successfully decrypt the timestamp with the hash of the user’s password, it will then send an Authentication Server Response (AS-REP) message that contains the Ticket Granting Ticket (TGT) to the user. Part of the AS-REP message is signed with the user’s password.\n\nFor each account found without preauthentication, an adversary may send an AS-REQ message without the encrypted timestamp and receive an AS-REP message with TGT data which may be encrypted with an insecure algorithm such as RC4. The recovered encrypted data may be vulnerable to offline Password Cracking attacks similarly to Kerberoasting and expose plaintext credentials.\n\nAn account registered to a domain, with or without special privileges, can be abused to list all domain accounts that have preauthentication disabled by utilizing Windows tools like PowerShell with an LDAP filter. Alternatively, the adversary may send an AS-REQ message for each user. If the DC responds without errors, the account does not require preauthentication and the AS-REP message will already contain the encrypted data.\n\nCracked hashes may enable Persistence, Privilege Escalation, and Lateral Movement via access to Valid Accounts.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows\n- Sub-technique of: T1558 Steal or Forge Kerberos Tickets - Adversaries may attempt to subvert Kerberos authentication by stealing or forging Kerberos tickets to enable Pass the Ticket.

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.

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 protective system functions as a prerequisite to subsequent attack execution or to allow for future faults and abnormal conditions to go unchecked. Detection of a Loss of Protection by operators can result in the shutdown of a process due to strict policies regarding protection 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.

Guardrails ensure that a payload only executes against an intended target and reduces collateral damage from an adversary’s campaign. Values an adversary can provide about a target system or environment to use as guardrails may include environment information such as location.\n\nGuardrails can be used to prevent exposure of capabilities in environments that are not intended to be compromised or operated within. This use of guardrails is distinct from typical System Checks. While use of System Checks may involve checking for known sandbox values and continuing with execution only if there is no match, the use of guardrails will involve checking for an expected target-specific value and only continuing with execution if there is such a match.\n\n**Classification.** - Tactics: defense-evasion\n- Platforms: Android, iOS\n\n**Sub-techniques.** - T1627.001 Geofencing: Adversaries may use a device’s geographical location to limit certain malicious behaviors.\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.

[…]\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.

Mobile operating systems have features and developer APIs to hide various artifacts, such as an application’s launcher icon. These APIs have legitimate usages, such as hiding an icon to avoid application drawer clutter when an application does not have a usable interface. Adversaries may abuse these features and APIs to hide artifacts from the user to evade detection.\n\n**Classification.** - Tactics: defense-evasion\n- Platforms: Android\n\n**Sub-techniques.** - T1628.001 Suppress Application Icon: A malicious application could suppress its icon from being displayed to the user in the application launcher.\n- T1628.003 Conceal Multimedia Files: Adversaries may attempt to hide multimedia files from the user.

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.

By doing this, an adversary’s modifications would most likely remain installed on the device for longer, allowing the adversary to continue to operate on that device.\n\nWhile there are many ways this can be accomplished, one method is by using the device’s sensors. By utilizing the various motion sensors on a device, such as accelerometer or gyroscope, an application could detect that the device is being interacted with. That way, the application could continue to run while the device is not in use but cease operating while the user is using the device, hiding anything that would indicate malicious activity was ongoing. Accessing the sensors in this way does not require any permissions from the user, so it would be completely transparent.\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.** - **Deploy Compromised Device Detection Method**: A variety of methods exist that can be used to enable enterprises to identify compromised (e.g. rooted/jailbroken) devices, whether using security mechanisms built directly into the device, third-party mobile security applications, enterprise mobility management (EMM)/mobile device management (MDM) capabilities, or other methods. Some methods may be trivial to evade while others may be more sophisticated.\n\n**Detection strategies and analytics.** - **Detection of User Evasion**\n  - For Android, detect User Evasion from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

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. An ESET researcher commented that internet disconnection does not guarantee system safety from infection or payload execution.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux, Network Devices\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- **Limit Hardware Installation**: Block users or groups from installing or using unapproved hardware on systems, including USB devices.\n- **Disable or Remove Feature or Program**: Remove or deny access to unnecessary and potentially vulnerable software to prevent abuse by adversaries.\n\n**Detection strategies and analytics.** - **Detection of Replication Through Removable Media**\n  - Real-time monitoring identifies a Universal Serial Bus (USB) storage device insertion event on an Industrial Control System (ICS) engineering or Human-Machine Interface (HMI) workstation where the device's hardware identifier (ID) is not in the authorized USB allowlist, immediately followed by process execution from the removable drive's path.

[…]\n\n## Reference: ATT&CK T0848 Rogue Master\n**ATT&CK T0848 Rogue Master (full record).** Adversaries may setup a rogue master to leverage control server functions to communicate with outstations. A rogue master can be used to send legitimate control messages to other control system devices, affecting processes in unintended ways. It may also be used to disrupt network communications by capturing and receiving the network traffic meant for the actual master. 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. 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 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. […]\n\n## Reference: ATT&CK T0849 Masquerading\n**ATT&CK T0849 Masquerading (full record).** Adversaries may use masquerading to disguise a malicious application or executable as another file, to avoid operator and engineer suspicion. 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. The mismatch -- name says one thing, binary integrity says another -- is the defining signal. OT operational-fidelity gate: Alert only when execution violates an approved signer/hash/path/parent/process or tool allowlist, or originates from an unauthorized user/tool, and is tied to an OT asset or follow-on OT-relevant action. […]\n\n## Reference: ATT&CK T0851 Rootkit\n**ATT&CK T0851 Rootkit (full record).** Adversaries may deploy rootkits to hide the presence of programs, files, network connections, services, drivers, and other system components. Rootkits are programs that hide the existence of malware by intercepting and modifying operating-system API calls that supply system information. Rootkits or rootkit-enabling functionality may reside at the user or kernel level in the operating system, or lower.\n\nFirmware rootkits that affect the operating system yield nearly full control of the system. While firmware rootkits are normally developed for the main processing board, they can also be developed for the I/O that is attached to an asset. Compromise of this firmware allows the modification of all of the process variables and functions the module engages in. This may result in commands being disregarded and false information being fed to the main device. By tampering with device processes, an adversary may inhibit its expected response functions and possibly enable Impact.\n\n**Classification.** - Tactics: evasion, inhibit-response-function\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- **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\n**Detection strategies and analytics.** - **Detection of Rootkit**\n  - Periodic or event-triggered integrity verification identifies a discrepancy between a field device's self-reported diagnostic state and an independently verified hardware/firmware fingerprint, indicating the device's reporting layer has been compromised. MITRE explicitly notes firmware/module rootkits 'can also be developed for the Input/Output (I/O) that is attached to an asset.'.

These device displays may reveal information regarding the ICS process, layout, control, and related schematics. In particular, an HMI can provide a lot of important industrial process information. Analysis of screen captures may provide the adversary with an understanding of intended operations and interactions between critical devices.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded, Windows, Linux\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 Screen Capture**\n  - Real-time monitoring identifies execution of screenshot utilities (scrot, import, xwd) on an Industrial Control System (ICS) Linux Human-Machine Interface (HMI), from a User Identifier (UID) that does not normally perform display operations.

Phishing for information is an attempt to trick targets into divulging information, frequently credentials or other actionable information. Phishing for information is different from Phishing in that the objective is gathering data from the victim rather than executing malicious code.\n\nAll forms of phishing are electronically delivered social engineering. Phishing can be targeted, known as spearphishing. 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 credential harvesting campaigns.\n\nAdversaries may also try to obtain information directly through the exchange of emails, instant messages, or other electronic conversation means. Victims may also receive phishing messages that direct them to call a phone number where the adversary attempts to collect confidential information.\n\nPhishing for information frequently involves social engineering techniques, such as posing as a source with a reason to collect information (ex: Establish Accounts or Compromise Accounts) and/or sending multiple, seemingly urgent messages. 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.\n\nPhishing for information may also involve evasive techniques, such as removing or manipulating emails or metadata/headers from compromised accounts being abused to send messages (e.g., Email Hiding Rules).\n\n**Classification.** - Tactics: reconnaissance\n- Platforms: PRE\n\n**Sub-techniques.** - T1598.004 Spearphishing Voice: Adversaries may use voice communications to elicit sensitive information that can be used during targeting.\n- T1598.001 Spearphishing Service: Adversaries may send spearphishing messages via third-party services to elicit sensitive information that can be used during targeting.\n- T1598.002 Spearphishing Attachment: Adversaries may send spearphishing messages with a malicious attachment to elicit sensitive information that can be used during targeting.

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 may create fake social media accounts and message employees for potential job opportunities. Doing so allows a plausible reason for asking about services, policies, and information about their environment. Adversaries may also use information from previous reconnaissance efforts (ex: Social Media or Search Victim-Owned Websites) to craft persuasive and believable lures.\n\n**Classification.** - Tactics: reconnaissance\n- Platforms: PRE\n- Sub-technique of: T1598 Phishing for Information - Adversaries may send phishing messages to elicit sensitive information that can be used during targeting.

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.

Control system devices often contain modular hardware devices. These devices may have their own set of firmware that is separate from the firmware of the main control system equipment.\n\nThis technique is similar to System Firmware, but is conducted on other system components that may not have the same capabilities or level of integrity checking. Although it results in a device re-image, malicious device firmware may provide persistent access to remaining devices.\n\nAn easy point of access for an adversary is the Ethernet card, which may have its own CPU, RAM, and operating system. The adversary may attack and likely exploit the computer on an Ethernet card. Exploitation of the Ethernet card computer may enable the adversary to accomplish additional attacks, such as the following:\n\n* Delayed Attack - The adversary may stage an attack in advance and choose when to launch it, such as at a particularly damaging time.\n* Brick the Ethernet Card - Malicious firmware may be programmed to result in an Ethernet card failure, requiring a factory return.\n* Random Attack or Failure - The adversary may load malicious firmware onto multiple field devices. Execution of an attack and the time it occurs is generated by a pseudo-random number generator.\n* A Field Device Worm - The adversary may choose to identify all field devices of the same model, with the end goal of performing a device-wide compromise.\n* Attack Other Cards on the Field Device - Although it is not the most important module in a field device, the Ethernet card is most accessible to the adversary and malware. Compromise of the Ethernet card may provide a more direct route to compromising other modules, such as the CPU module.\n\n**Classification.** - Tactics: persistence, inhibit-response-function, impair-process-control\n- Platforms: Embedded\n- Sub-technique of: T1693 Modify Firmware - Firmware is low-level software embedded in hardware that enables systems and devices to function properly and is commonly found in ICS environments.\n\n**Mitigations.** - **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering.

Insecure credentials may appear as default credentials which are pre-configured credentials on a system, device, or software that are well-known in documentation or hard-coded credentials which are built into the system, device, or software that cannot be changed or not easily changed because of the impact on control processes.\nAdversaries often times use insecure credentials to evade detection as they are typically forgotten about by system and device owners.\n\n**Classification.** - Tactics: persistence, lateral-movement\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Sub-techniques.** - T1694.002 Hardcoded Credentials: Adversaries may leverage credentials that are hardcoded in software or firmware to gain an unauthorized interactive user session to an asset.\n- T1694.001 Default Credentials: Adversaries may leverage manufacturer or supplier set default credentials on control system 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\n**Detection strategies and analytics.** - **Detection of Insecure Credentials**\n  - Real-time monitoring identifies successful authentication to Windows-hosted Industrial Control System (ICS) applications using credentials matching known default or hardcoded vendor passwords.

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- **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.

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.

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.

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.

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. Ptrace system call injection can also be done with `PTRACE_POKETEXT`/`PTRACE_POKEDATA`, which copy data to a specific address in the target processes’ memory (ex: the current address of the next instruction).\n\nPtrace system call injection may not be possible targeting processes that are non-child processes and/or have higher-privileges.\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges.

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. Execution via proc memory 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: 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.

Scans may range from simple pings (ICMP requests and responses) to more nuanced scans that may reveal host software/versions via server banners or other network artifacts.

[…]\n\n## Reference: ATT&CK T1595.003 Wordlist Scanning\n**ATT&CK T1595.003 Wordlist Scanning (full record).** Adversaries may iteratively probe infrastructure using brute-forcing and crawling techniques. While this technique employs similar methods to Brute Force, its goal is the identification of content and infrastructure rather than the discovery of valid credentials. Wordlists used in these scans may contain generic, commonly used names and file extensions or terms specific to a particular software. Adversaries may also create custom, target-specific wordlists using data gathered from other Reconnaissance techniques (ex: Gather Victim Org Information, or Search Victim-Owned Websites).\n\nFor example, adversaries may use web content discovery tools such as Dirb, DirBuster, and GoBuster and generic or custom wordlists to enumerate a website’s pages and directories. This can help them to discover old, vulnerable pages or hidden administrative portals that could become the target of further operations (ex: Exploit Public-Facing Application or Brute Force).\n\nAs cloud storage solutions typically use globally unique names, adversaries may also use target-specific wordlists and tools such as s3recon and GCPBucketBrute to enumerate public and private buckets on cloud infrastructure. Once storage objects are discovered, adversaries may leverage Data from Cloud Storage to access valuable information that can be exfiltrated or used to escalate privileges and move laterally.\n\n**Classification.** - Tactics: reconnaissance\n- Platforms: PRE\n- Sub-technique of: T1595 Active Scanning - Adversaries may execute active reconnaissance scans to gather information that can be used during targeting.

Threat actors can query nameservers for a target organization directly, or search through centralized repositories of logged DNS query responses (known as passive DNS). Adversaries may also seek and target DNS misconfigurations/leaks that reveal information about internal networks.

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.

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.

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. […]\n\n## Reference: ATT&CK T1685.001 Disable or Modify Windows Event Log\n**ATT&CK T1685.001 Disable or Modify Windows Event Log (full record).** 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.

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.

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.

Domain trusts provide a mechanism for a domain to allow access to resources based on the authentication procedures of another domain. Domain trusts allow the users of the trusted domain to access resources in the trusting domain. The information discovered may help the adversary conduct SID-History Injection, Pass the Ticket, and Kerberoasting. Domain trusts can be enumerated using the `DSEnumerateDomainTrusts` Win32 API call,.NET methods, and LDAP.

Such services provide a centralized means of managing identity resources such as devices and accounts, and often include configuration settings that may apply between domains or tenants such as trust relationships, identity syncing, or identity federation.\n\nModifications to domain or tenant settings may include altering domain Group Policy Objects (GPOs) in Microsoft Active Directory (AD) or changing trust settings for domains, including federation trusts relationships between domains or tenants.\n\nWith sufficient permissions, adversaries can modify domain or tenant policy settings. Since configuration settings for these services apply to a large number of identity resources, there are a great number of potential attacks malicious outcomes that can stem from this abuse. Examples of such abuse include:\n\n* modifying GPOs to push a malicious Scheduled Task to computers throughout the domain environment\n* modifying domain trusts to include an adversary-controlled domain, allowing adversaries to forge access tokens that will subsequently be accepted by victim domain resources\n* changing configuration settings within the AD environment to implement a Rogue Domain Controller.\n* adding new, adversary-controlled federated identity providers to identity tenants, allowing adversaries to authenticate as any user managed by the victim tenant\n\nAdversaries may temporarily modify domain or tenant policy, carry out a malicious action(s), and then revert the change to remove suspicious indicators.\n\n**Classification.** - Tactics: defense-impairment, privilege-escalation\n- Platforms: Windows, Identity Provider\n\n**Sub-techniques.** - T1484.002 Trust Modification: Adversaries may add new domain trusts, modify the properties of existing domain trusts, or otherwise change the configuration of trust relationships between domains and tenants to evade defenses and/o.\n- T1484.001 Group Policy Modification: Adversaries may modify Group Policy Objects (GPOs) to subvert the intended discretionary access controls for a domain, usually with the intention of escalating privileges on the domain.\n\n**Mitigations.** - **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. […]\n\n## Reference: ATT&CK T1484.001 Group Policy Modification\n**ATT&CK T1484.001 Group Policy Modification (full record).** Adversaries may modify Group Policy Objects (GPOs) to subvert the intended discretionary access controls for a domain, usually with the intention of escalating privileges on the domain. Group policy allows for centralized management of user and computer settings in Active Directory (AD). GPOs are containers for group policy settings made up of files stored within a predictable network path `\\<DOMAIN>\\SYSVOL\\<DOMAIN>\\Policies\\`.\n\nLike other objects in AD, GPOs have access controls associated with them. By default all user accounts in the domain have permission to read GPOs. It is possible to delegate GPO access control permissions, e.g. write access, to specific users or groups in the domain.\n\nMalicious GPO modifications can be used to implement many other malicious behaviors such as Scheduled Task/Job, Disable or Modify Tools, Ingress Tool Transfer, Create Account, Service Execution, and more. Since GPOs can control so many user and machine settings in the AD environment, there are a great number of potential attacks that can stem from this GPO abuse.\n\nFor example, publicly available scripts such as `New-GPOImmediateTask` can be leveraged to automate the creation of a malicious Scheduled Task/Job by modifying GPO settings, in this case modifying `<GPO_PATH>\\Machine\\Preferences\\ScheduledTasks\\ScheduledTasks.xml`. In some cases an adversary might modify specific user rights like SeEnableDelegationPrivilege, set in `<GPO_PATH>\\MACHINE\\Microsoft\\Windows NT\\SecEdit\\GptTmpl.inf`, to achieve a subtle AD backdoor with complete control of the domain because the user account under the adversary's control would then be able to modify GPOs.\n\n**Classification.** - Tactics: defense-impairment, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1484 Domain or Tenant Policy Modification - Adversaries may modify the configuration settings of a domain or identity tenant to evade defenses and/or escalate privileges in centrally managed environments. […]\n\n## Reference: ATT&CK T1484.002 Trust Modification\n**ATT&CK T1484.002 Trust Modification (full record).** Adversaries may add new domain trusts, modify the properties of existing domain trusts, or otherwise change the configuration of trust relationships between domains and tenants to evade defenses and/or elevate privileges.Trust details, such as whether or not user identities are federated, allow authentication and authorization properties to apply between domains or tenants for the purpose of accessing shared resources. These trust objects may include accounts, credentials, and other authentication material applied to servers, tokens, and domains.\n\nManipulating these trusts may allow an adversary to escalate privileges and/or evade defenses by modifying settings to add objects which they control. For example, in Microsoft Active Directory (AD) environments, this may be used to forge SAML Tokens without the need to compromise the signing certificate to forge new credentials. Instead, an adversary can manipulate domain trusts to add their own signing certificate. An adversary may also convert an AD domain to a federated domain using Active Directory Federation Services (AD FS), which may enable malicious trust modifications such as altering the claim issuance rules to log in any valid set of credentials as a specified user.\n\nAn adversary may also add a new federated identity provider to an identity tenant such as Okta or AWS IAM Identity Center, which may enable the adversary to authenticate as any user of the tenant. This may enable the threat actor to gain broad access into a variety of cloud-based services that leverage the identity tenant. For example, in AWS environments, an adversary that creates a new identity provider for an AWS Organization will be able to federate into all of the AWS Organization member accounts without creating identities for each of the member accounts.\n\n**Classification.** - Tactics: defense-impairment, privilege-escalation\n- Platforms: Identity Provider, Windows\n- Sub-technique of: T1484 Domain or Tenant Policy Modification - Adversaries may modify the configuration settings of a domain or identity tenant to evade defenses and/or escalate privileges in centrally managed environments.\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).

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.

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). […]\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.

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.

[…]\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.

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.

For example, adversaries may enumerate a list of VMs on an ESXi hypervisor using a Hypervisor CLI such as `esxcli` or `vim-cmd` (e.g. `esxcli vm process list or vim-cmd vmsvc/getallvms`). Adversaries may also directly leverage a graphical user interface, such as VMware vCenter, in order to view virtual machines on a host.\n\nAdversaries may use the information from Virtual Machine Discovery during discovery to shape follow-on behaviors.

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**Classification.** - Tactics: execution\n- Platforms: Windows, macOS, Linux\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 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.

Reflective loading involves allocating then executing payloads directly within the memory of the process, vice creating a thread or process backed by a file path on disk (e.g., Shared Modules).\n\nReflectively loaded payloads may be compiled binaries, anonymous files (only present in RAM), or just snubs of fileless executable code (ex: position-independent shellcode). For example, the `Assembly.Load` method executed by PowerShell may be abused to load raw code into the running process.\n\nReflective code injection is very similar to Process Injection except that the “injection” loads code into the processes’ own memory instead of that of a separate process. Reflective loading may evade process-based detections since the execution of the arbitrary code may be masked within a legitimate or otherwise benign process. Reflectively loading payloads directly into memory may also avoid creating files or other artifacts on disk, while also enabling malware to keep these payloads encrypted (or otherwise obfuscated) until execution.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n\n**Detection strategies and analytics.** - **Detection Strategy for Reflective Code Loading**\n  - Detect anomalous chains of memory allocation and execution inside the same process (e.g., VirtualAlloc → memcpy → VirtualProtect → CreateThread).

To circumvent this, adversaries may abuse the automatic generation of push notifications to MFA services such as Duo Push, Microsoft Authenticator, Okta, or similar services to have the user grant access to their account. If adversaries lack credentials to victim accounts, they may also abuse automatic push notification generation when this option is configured for self-service password reset (SSPR).\n\nIn some cases, adversaries may continuously repeat login attempts in order to bombard users with MFA push notifications, SMS messages, and phone calls, potentially resulting in the user finally accepting the authentication request in response to “MFA fatigue.”\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows, Linux, macOS, IaaS, SaaS, Office Suite, Identity Provider\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- **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- **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 T1622 Debugger Evasion\n**ATT&CK T1622 Debugger Evasion (full record).** Adversaries may employ various means to detect and avoid debuggers. Debuggers are typically used by defenders to trace and/or analyze the execution of potential malware payloads.\n\nDebugger evasion may include changing behaviors based on the results of the checks for the presence of artifacts indicative of a debugged environment. Similar to Virtualization/Sandbox Evasion, if the adversary detects a debugger, they may alter their malware to disengage from the victim or conceal the core functions of the implant. They may also search for debugger artifacts before dropping secondary or additional payloads.\n\nSpecific checks will vary based on the target and/or adversary. On Windows, this may involve Native API function calls such as `IsDebuggerPresent` and ` NtQueryInformationProcess`, or manually checking the `BeingDebugged` flag of the Process Environment Block (PEB). On Linux, this may involve querying `/proc/self/status` for the `TracerPID` field, which indicates whether or not the process is being traced by dynamic analysis tools. Other checks for debugging artifacts may also seek to enumerate hardware breakpoints, interrupt assembly opcodes, time checks, or measurements if exceptions are raised in the current process (assuming a present debugger would “swallow” or handle the potential error).\n\nMalware may also leverage Structured Exception Handling (SEH) to detect debuggers by throwing an exception and detecting whether the process is suspended. SEH handles both hardware and software expectations, providing control over the exceptions including support for debugging. If a debugger is present, the program’s control will be transferred to the debugger, and the execution of the code will be suspended. If the debugger is not present, control will be transferred to the SEH handler, which will automatically handle the exception and allow the program’s execution to continue.\n\nAdversaries may use the information learned from these debugger checks during automated discovery to shape follow-on behaviors. Debuggers can also be evaded by detaching the process or flooding debug logs with meaningless data via messages produced by looping Native API function calls such as `OutputDebugStringW`. […]"}]}

StreaMon is a carefully designed data-plane abstraction devised to scalably decouple the “programming logic” of a traffic analysis application (tracked states, features, anomaly conditions, etc.) from elementary primitives (counting and metering, matching, events generation, etc), efficiently pre-implemented in the probes, and used as common instruction set for supporting the desired logic. Multi-stage multi-step real-time tracking and detection algorithms are supported via the ability to deploy custom states, relevant state transitions, and associated monitoring actions and triggering conditions. Such a separation entails platform-independent, portable, online traffic analysis tasks written in a high level language, without requiring developers to access the monitoring device internals and program their custom monitoring logic via low level compiled languages (e.g., C, assembly, VHDL). We validate our design by developing a prototype and a set of simple (but functionally demanding) use-case applications and by testing them over real traffic traces.\n\n1\n\n**Introduction.** The sheer volume of networked information, in conjunction with the complexity and polymorphous nature of modern cyberthreats, calls for scalable, accurate, and, at the same time, flexible and programmable monitoring systems [ 13, 11 ]. The challenge is to promptly react to fastly mutating needs by deploying custom traffic analyses, capable of tracking event chains and multi-stage attacks, and efficiently handle the many heterogeneous features, events, and conditions which characterize an operational failure, a network application mis-behavior, an anomaly or an incoming attack. Such needed level of flexibility and programmability should address scalability by design, through systematic exploitation of stream-based analysis techniques. And, even more challenging, traffic analyses and mitigation primitives should be ideally brought\n\ninside the monitoring probes themselves at data plane, so as to avoid exporting traffic data to central analysis points, an hardly adequate way to cope with the traffic scale and the strict (ideally real time) mitigation delay requirements. […]\n\n## Reference: The process of macroprudential oversight in Europe\n**Implementation.** : Here, activities in the organization are, if necessary, adapted to findings from previous stages.\n\n5.\n\nMonitoring and control: Here, performance metrics are analyzed to see whether these give raise to further changes in the organization.\n\n6.\n\nRefinement: After an analysis of process performance, further work in the analysis and design phases of the BPM cycle might be necessary.\n\nIn the context of these six stages, the assessment of process readiness conducted in this paper falls into the second stage. Despite this, we hope that the ideas and thoughts brought forward in this paper could lead to a more formalized approach to improving macroprudential oversight (stage one: planning). Likewise, we have not made an attempt at improving design and modeling (stage three), as we are not presenting a detailed documentation of the process using a standard annotation for representing all the activities therein. With this study, our focus is thus on establishing whether there is a common understanding of the process, explicit or implicit, among the European System of Financial Supervisors, and on identifying potential bottlenecks in the underlying enablers of a mature process.\n\n3.2 Process Readiness\n\nProcess analysis, as one of the six distinct phases of BPM, aims at understanding current states of organizational processes. Given the common complexity of today’s processes, analysis invokes structured approaches to gain a better understanding of the inner workings of processes and their associated performance targets. One widely known structured approach to understanding the state of a process is the assessment of process readiness or maturity, as introduced by Hammer [23], Hammer [24].\n\nTo define a mature, high-performance process, one can assess process-specific characteristics. Hammer [23] defines five critical enablers for well-functioning processes: ( i) process design, ( ii) process metrics, ( iii) process performers, ( iv) process infrastructure, and ( v) process owners. The design of the process goes back to the specification of what tasks are to be performed, by whom, and what the associated inputs and outputs are. This also involves an understanding of the organization(s) involved and how the activities interact to produce a desired outcome. The metrics of the process detail the desired outcome in more specific terms.

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. Prior to Android 7, applications could utilize the `ps` command or examine the `/proc` directory on the device.\n\nIn iOS, applications have previously been able to use the `sysctl` command to obtain a list of running processes.

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.

Additionally, if the cloud environment is connected to a on-premises environment, adversaries may be able to identify services running on non-cloud systems as well.\n\nWithin macOS environments, adversaries may use the native Bonjour application to discover services running on other macOS hosts within a network. The Bonjour mDNSResponder daemon automatically registers and advertises a host’s registered services on the network. For example, adversaries can use a mDNS query (such as `dns-sd -B _ssh._tcp.`) to find other systems broadcasting the ssh service.\n\n**Classification.** - Tactics: discovery\n- Platforms: Containers, IaaS, Linux, macOS, Network Devices, 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- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\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\n**Detection strategies and analytics.** - **Behavioral Detection Strategy for Network Service Discovery Across Platforms**\n  - Detects processes performing network enumeration (e.g., port scans, service probing) by correlating process creation, socket connections, and sequential destination IP probing within a time window. […]\n\n## Reference: ATT&CK T1047 Windows Management Instrumentation\n**ATT&CK T1047 Windows Management Instrumentation (full record).** Adversaries may abuse Windows Management Instrumentation (WMI) to execute malicious commands and payloads. WMI is designed for programmers and is the infrastructure for management data and operations on Windows systems. WMI is an administration feature that provides a uniform environment to access Windows system components.\n\nThe WMI service enables both local and remote access, though the latter is facilitated by Remote Services such as Distributed Component Object Model and Windows Remote Management. Remote WMI over DCOM operates using port 135, whereas WMI over WinRM operates over port 5985 when using HTTP and 5986 for HTTPS.\n\nAn adversary can use WMI to interact with local and remote systems and use it as a means to execute various behaviors, such as gathering information for Discovery as well as Execution of commands and payloads. For example, `wmic.exe` can be abused by an adversary to delete shadow copies with the command `wmic.exe Shadowcopy Delete` (i.e., Inhibit System Recovery).\n\n**Note:** `wmic.exe` is deprecated as of January of 2024, with the WMIC feature being “disabled by default” on Windows 11+. WMIC will be removed from subsequent Windows releases and replaced by PowerShell as the primary WMI interface. In addition to PowerShell and tools like `wbemtool.exe`, COM APIs can also be used to programmatically interact with WMI via C++,.NET, VBScript, etc.\n\n**Classification.** - Tactics: execution\n- Platforms: Windows\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- **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 T1048 Exfiltration Over Alternative Protocol\n**ATT&CK T1048 Exfiltration Over Alternative Protocol (full record).** Adversaries may steal data by exfiltrating it over a different protocol than that of the existing command and control channel. The data may also be sent to an alternate network location from the main command and control server.\n\nAlternate protocols include FTP, SMTP, HTTP/S, DNS, SMB, or any other network protocol not being used as the main command and control channel. Adversaries may also opt to encrypt and/or obfuscate these alternate channels.\n\nExfiltration Over Alternative Protocol can be done using various common operating system utilities such as Net/SMB or FTP. On macOS and Linux `curl` may be used to invoke protocols such as HTTP/S or FTP/S to exfiltrate data from a system.\n\nMany IaaS and SaaS platforms (such as Microsoft Exchange, Microsoft SharePoint, GitHub, and AWS S3) support the direct download of files, emails, source code, and other sensitive information via the web console or Cloud API.\n\n**Classification.** - Tactics: exfiltration\n- Platforms: ESXi, IaaS, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1048.002 Exfiltration Over Asymmetric Encrypted Non-C2 Protocol: Adversaries may steal data by exfiltrating it over an asymmetrically encrypted network protocol other than that of the existing command and control channel.\n- T1048.003 Exfiltration Over Unencrypted Non-C2 Protocol: Adversaries may steal data by exfiltrating it over an un-encrypted network protocol other than that of the existing command and control channel.\n- T1048.001 Exfiltration Over Symmetric Encrypted Non-C2 Protocol: Adversaries may steal data by exfiltrating it over a symmetrically encrypted network protocol other than that of the existing command and control channel.\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.

The data may also be sent to an alternate network location from the main command and control server.\n\nSymmetric encryption algorithms are those that use shared or the same keys/secrets on each end of the channel. This requires an exchange or pre-arranged agreement/possession of the value used to encrypt and decrypt data.\n\nNetwork protocols that use asymmetric encryption often utilize symmetric encryption once keys are exchanged, but adversaries may opt to manually share keys and implement symmetric cryptographic algorithms (ex: RC4, AES) vice using mechanisms that are baked into a protocol. This may result in multiple layers of encryption (in protocols that are natively encrypted such as HTTPS) or encryption in protocols that not typically encrypted (such as HTTP or FTP).\n\n**Classification.** - Tactics: exfiltration\n- Platforms: Linux, macOS, Windows, ESXi\n- Sub-technique of: T1048 Exfiltration Over Alternative Protocol - Adversaries may steal data by exfiltrating it over a different protocol than that of the existing command and control channel. The data may also be sent to an alternate network location from the main command and control server.\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- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\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.

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.

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.

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## Reference: ATT&CK T1204.002 Malicious File\n**ATT&CK T1204.002 Malicious File (full record).** An adversary may rely upon a user opening a malicious file in order to gain execution. Users may be subjected to social engineering to get them to open a file that will lead to code execution. This user action will typically be observed as follow-on behavior from Spearphishing Attachment. Adversaries may use several types of files that require a user to execute them, including.doc,.pdf,.xls,.rtf,.scr,.exe,.lnk,.pif,.cpl,.reg, and.iso.\n\nAdversaries may employ various forms of Masquerading and Obfuscated Files or Information to increase the likelihood that a user will open and successfully execute a malicious file. These methods may include using a familiar naming convention and/or password protecting the file and supplying instructions to a user on how to open it.\n\nWhile Malicious File frequently occurs shortly after Initial Access it may occur at other phases of an intrusion, such as when an adversary places a file in a shared directory or on a user's desktop hoping that a user will click on it. This activity may also be seen shortly after Internal Spearphishing.\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.** - **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- **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 T1204.003 Malicious Image\n**ATT&CK T1204.003 Malicious Image (full record).** Adversaries may rely on a user running a malicious image to 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. 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.** - **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- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\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. 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 T1204.004 Malicious Copy and Paste\n**ATT&CK T1204.004 Malicious Copy and Paste (full record).** An adversary may rely upon a user copying and pasting code in order to gain execution. Users may be subjected to social engineering to get them to copy and paste code directly into a Command and Scripting Interpreter. 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. When a user attempts to open an attachment, they may be presented with a fake error and offered a malicious command to paste as a solution, consistent with the \"ClickFix\" strategy.\n\nTricking a user into executing a command themselves may help to bypass email filtering, browser sandboxing, or other mitigations designed to protect users against malicious downloaded files.\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.

[…]\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. 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. This mitigation can be implemented through the following measures:\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\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. 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\n**Detection strategies and analytics.** - **User-Initiated Malicious Library Installation via Package Manager (T1204.005)**\n  - User-initiated installation of Python (pip), NodeJS (npm), or other language libraries, followed by unexpected network connections, credential access, or startup file modifications.

The adversary may then perform actions as the logged-on user.\n\n## Mitigations\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- **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- **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- **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\n## Detection strategies and analytics\n- **Behavioral Detection of Unauthorized VNC Remote Control Sessions**\n  - Detection of VNC service or executable starting unexpectedly, followed by user session creation and interactive desktop activity (mouse/keyboard simulation). (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Security:EventCode=4624, 4648, NSM:Flow:port 5900 inbound)\n  - Spawning of VNC-related processes (e.g., `x11vnc`, `vncserver`) coupled with authentication logs and port listening behavior on TCP 5900. (telemetry: auditd:EXECVE:None, linux:syslog:None, NSM:Flow:TCP port 5900 open)\n  - Detection of VNC-based remote control via `screensharingd` activity in Unified Logs along with concurrent remote login activity or suspicious user interaction.

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- **Behavioral Detection of Remote Cloud Logins via Valid Accounts**\n  - Cloud login from atypical geolocation or user-agent string, followed by resource enumeration or infrastructure manipulation using cloud CLI/API (telemetry: AWS:CloudTrail:ConsoleLogin, AssumeRole, ListResources, gcp:audit:None)\n  - Federated login using SSO or OAuth grant to cloud control plane, followed by directory or permissions enumeration (telemetry: Okta:SystemLog:user.authentication.sso, app.oauth.grant)\n  - Login to M365 or Google Workspace from CLI tools or unexpected source IPs, followed by mailbox or document access (telemetry: m365:unified:FileAccessed, MailboxAccessed, m365:unified:UserLoggedIn)\n  - Remote access to third-party SaaS with OAuth or API tokens post-initial compromise, followed by sensitive data access or configuration changes (telemetry: saas:auth:LoginSuccess, APIKeyUse, AdminAction)\n\n## Tracked users (groups, malware, tools)\n- C0027 (campaign): C0027 was a financially-motivated campaign linked to Scattered Spider that targeted telecommunications and business process outsourcing (BPO) companies from at least June through D.\n- Storm-0501 (intrusion-set): Storm-0501 is a financially motivated cyber criminal group that uses commodity and open-source tools to conduct ransomware operations.\n- Mini Shai-Hulud (malware): Mini Shai-Hulud is a credential stealer and self-replicating supply chain worm, derived from Shai-Hulud, that has been used by TeamPCP to target Continuous Integration and Continuo.\n- APT29 (intrusion-set): APT29 is threat group that has been attributed to Russia's Foreign Intelligence Service (SVR).\n- Scattered Spider (intrusion-set): Scattered Spider is a native English-speaking cybercriminal group active since at least 2022.\n\n## Reference: ATT&CK T1608.007 AI Result Poisoning\n**ATT&CK T1608.007 AI Result Poisoning (full record).** Adversaries may manipulate publicly accessible web content to influence generative AI systems or AI-powered search engines into retrieving, citing, or recommending attacker-controlled information.\n\nUnlike traditional SEO Poisoning, which primarily attempts to influence the ordering of conventional search results, AI Result Poisoning targets systems that synthesize information from multiple sources and provide a direct answer to the user. Adversaries may create malicious or misleading websites, publish fabricated claims, generate supporting articles, or establish multiple apparently independent sources that reinforce the same information. These sources may then be retrieved by AI systems using web search or retrieval-augmented generation and incorporated into generated responses.\n\nAdversaries may use this technique to recommend or link to phishing sites, fraudulent online stores, malicious downloads, impersonation pages, or other attacker-controlled infrastructure. It can also be used to promote misinformation or fabricated claims without requiring access to the underlying AI model, system prompt, or application infrastructure. Because the malicious content can resemble ordinary marketing, editorial, or informational material, traditional prompt injection and malware-focused detections may not identify the activity.\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. 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 AI Result Poisoning**\n  - No target-side behavioral analytic.

A container administration service such as the Docker daemon, the Kubernetes API server, or the kubelet may allow remote management of containers within an environment.\n\nIn Docker, adversaries may specify an entrypoint during container deployment that executes a script or command, or they may use a command such as `docker exec` to execute a command within a running container. In Kubernetes, if an adversary has sufficient permissions, they may gain remote execution in a container in the cluster via interaction with the Kubernetes API server, the kubelet, or by running a command such as `kubectl exec`.\n\n**Classification.** - Tactics: execution\n- Platforms: Containers\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- **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- **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 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. […]\n\n## Reference: ATT&CK T1610 Deploy Container\n**ATT&CK T1610 Deploy Container (full record).** Adversaries may deploy a container into an environment to facilitate execution or evade defenses. In some cases, adversaries may deploy a new container to execute processes associated with a particular image or deployment, such as processes that execute or download malware. In others, an adversary may deploy a new container configured without network rules, user limitations, etc. to bypass existing defenses within the environment. In Kubernetes environments, an adversary may attempt to deploy a privileged or vulnerable container into a specific node in order to Escape to Host and access other containers running on the node.\n\nContainers can be deployed by various means, such as via Docker's `create` and `start` APIs or via a web application such as the Kubernetes dashboard or Kubeflow. In Kubernetes environments, containers may be deployed through workloads such as ReplicaSets or DaemonSets, which can allow containers to be deployed across multiple nodes. Adversaries may deploy containers based on retrieved or built malicious images or from benign images that download and execute malicious payloads at runtime.\n\n**Classification.** - Tactics: execution\n- Platforms: Containers\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- **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\n## Reference: ATT&CK T1611 Escape to Host\n**ATT&CK T1611 Escape to Host (full record).** Adversaries may break out of a container or virtualized environment to gain access to the underlying host. This can allow an adversary access to other containerized or virtualized resources from the host level or to the host itself. In principle, containerized / virtualized resources should provide a clear separation of application functionality and be isolated from the host environment.\n\nThere are multiple ways an adversary may escape from a container to a host environment. Examples include creating a container configured to mount the host’s filesystem using the bind parameter, which allows the adversary to drop payloads and execute control utilities such as cron on the host; utilizing a privileged container to run commands or load a malicious kernel module on the underlying host; or abusing system calls such as `unshare` and `keyctl` to escalate privileges and steal secrets.\n\nAdditionally, an adversary may be able to exploit a compromised container with a mounted container management socket, such as `docker.sock`, to break out of the container via a Container Administration Command. 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**Classification.** - Tactics: privilege-escalation\n- Platforms: Windows, Linux, Containers, ESXi\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- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms.

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.

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.

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.

Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private that should not be distributed. Due to how asymmetric algorithms work, 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, ElGamal, and ECDSA.\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.

[…]\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.

The adversary may then perform management actions or access cloud-hosted resources as the logged-on user.\n\nMany enterprises federate centrally managed user identities to cloud services, allowing users to login with their domain credentials in order to access the cloud control plane. Similarly, adversaries may connect to available cloud services through the web console or through the cloud command line interface (CLI) (e.g., Cloud API), using commands such as `Connect-AZAccount` for Azure PowerShell, `Connect-MgGraph` for Microsoft Graph PowerShell, and `gcloud auth login` for the Google Cloud CLI.\n\nIn some cases, adversaries may be able to authenticate to these services via Application Access Token instead of a username and password.\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. 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.** - **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 T1098.006 Additional Container Cluster Roles\n**ATT&CK T1098.006 Additional Container Cluster Roles (full record).** 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. For example, an adversary with sufficient permissions may create a RoleBinding or a ClusterRoleBinding to bind a Role or ClusterRole to a Kubernetes account. Where attribute-based access control (ABAC) is in use, an adversary with sufficient permissions may modify a Kubernetes ABAC policy to give the target account additional permissions.\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.\n\nNote that where container orchestration systems are deployed in cloud environments, as with Google Kubernetes Engine, Amazon Elastic Kubernetes Service, and Azure Kubernetes Service, cloud-based role-based access control (RBAC) assignments or ABAC policies can often be used in place of or in addition to local permission assignments. In these cases, this technique may be used in conjunction with Additional Cloud Roles.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Containers\n- Sub-technique of: T1098 Account Manipulation - Adversaries may manipulate accounts to maintain and/or elevate access to victim systems.

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. […]\n\n## Reference: ATT&CK T1098.007 Additional Local or Domain Groups\n**ATT&CK T1098.007 Additional Local or Domain Groups (full record).** An adversary may add additional local or domain groups to an adversary-controlled account to maintain persistent access to a system or domain.\n\nOn Windows, accounts may use the `net localgroup` and `net group` commands to add existing users to local and domain groups. On Linux, adversaries may use the `usermod` command for the same purpose.\n\nFor example, accounts may be added to the local administrators group on Windows devices to maintain elevated privileges. They may also be added to the Remote Desktop Users group, which allows them to leverage Remote Desktop Protocol to log into the endpoints in the future. Adversaries may also add accounts to VPN user groups to gain future persistence on the network. On Linux, accounts may be added to the sudoers group, allowing them to persistently leverage Sudo and Sudo Caching for elevated privileges.\n\nIn Windows environments, machine accounts may also be added to domain groups. This allows the local SYSTEM account to gain privileges on the domain.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows, macOS, Linux\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**Detection strategies and analytics.** - **Suspicious Addition to Local or Domain Groups**\n  - Detects unauthorized additions of users or machine accounts to privileged local or domain groups (e.g., Administrators, Remote Desktop Users). (telemetry: WinEventLog:Security:EventCode=4728, 4729, 4732, 4733, 4756, 4757)\n  - Detects unexpected use of usermod, gpasswd, or direct modification of /etc/group to elevate user group membership. […]\n\n## Reference: ATT&CK T1102 Web Service\n**ATT&CK T1102 Web Service (full record).** Adversaries may use an existing, legitimate external Web service as a means for relaying data to/from a compromised system. Popular websites, cloud services, 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, Microsoft, 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 Web services 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**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Windows\n\n**Sub-techniques.** - T1102.003 One-Way Communication: Adversaries may use an existing, legitimate external Web service as a means for sending commands to a compromised system without receiving return output over the Web service channel.\n- T1102.001 Dead Drop Resolver: Adversaries may use an existing, legitimate external Web service to host information that points to additional command and control (C2) infrastructure.\n- T1102.002 Bidirectional Communication: 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.\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. […]"}]}

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. […]"}]}

HTML documents can store large binary objects known as JavaScript Blobs (immutable data that represents raw bytes) that can later be constructed into file-like objects. Data may also be stored in Data URLs, which enable embedding media type or MIME files inline of HTML documents. HTML5 also introduced a download attribute that may be used to initiate file downloads.\n\nAdversaries may deliver payloads to victims that bypass security controls through HTML Smuggling by abusing JavaScript Blobs and/or HTML5 download attributes. Security controls such as web content filters may not identify smuggled malicious files inside of HTML/JS files, as the content may be based on typically benign MIME types such as `text/plain` and/or `text/html`. Malicious files or data can be obfuscated and hidden inside of HTML files through Data URLs and/or JavaScript Blobs and can be deobfuscated when they reach the victim (i.e. Deobfuscate/Decode Files or Information), potentially bypassing content filters.\n\nFor example, JavaScript Blobs can be abused to dynamically generate malicious files in the victim machine and may be dropped to disk by abusing JavaScript functions such as `msSaveBlob`.\n\n## Reference: ATT&CK AN1541 Analytic 1541\n**ATT&CK AN1541 Analytic 1541 (full record).** Detect commands such as 'esxcli system shutdown' or 'vim-cmd vmsvc/power.shutdown' executed outside of maintenance windows or via unusual users.

Scripts and executables may contain variables names and other strings that help developers document code functionality. Symbols are often created by an operating system’s `linker` when executable payloads are compiled. Reverse engineers use these symbols and strings to analyze code and to identify functionality in payloads.\n\nAdversaries may use stripped payloads in order to make malware analysis more difficult. For example, compilers and other tools may provide features to remove or obfuscate strings and symbols. Adversaries have also used stripped payload formats, such as run-only AppleScripts, a compiled and stripped version of AppleScript, to evade detection and analysis. The lack of human-readable information may directly hinder detection and analysis of payloads.\n\n## Reference: ATT&CK T1547.010 Port Monitors\n**ATT&CK T1547.010 Port Monitors (full record).** Adversaries may use port monitors to run an adversary supplied DLL during system boot for persistence or privilege escalation. A port monitor can be set through the `AddMonitor` API call to set a DLL to be loaded at startup. This DLL can be located in `C:\\Windows\\System32` and will be loaded and run by the print spooler service, `spoolsv.exe`, under SYSTEM level permissions on boot.\n\nAlternatively, an arbitrary DLL can be loaded if permissions allow writing a fully-qualified pathname for that DLL to the `Driver` value of an existing or new arbitrarily named subkey of `HKLM\\SYSTEM\\CurrentControlSet\\Control\\Print\\Monitors`. The Registry key contains entries for the following:\n\n* Local Port\n* Standard TCP/IP Port\n* USB Monitor\n* WSD Port\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 pattern often indicates an attempt to persist a malicious DLL via the print monitor mechanism, particularly when correlated with creation of files in `C:\\Windows\\System32` not tied to known patches or installations. (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=7, WinEventLog:Sysmon:EventCode=13)\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. 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. […]\n\n## Reference: ATT&CK T1547.013 XDG Autostart Entries\n**ATT&CK T1547.013 XDG Autostart Entries (full record).** Adversaries may add or modify XDG Autostart Entries to execute malicious programs or commands when a user’s desktop environment is loaded at login. 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. Operating systems may have mechanisms for automatically running a program on system boot or account logon.\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 T1547.014 Active Setup\n**ATT&CK T1547.014 Active Setup (full record).** Adversaries may achieve persistence by adding a Registry key to the Active Setup of the local machine. Active Setup is a Windows mechanism that is used to execute programs when a user logs in. The value stored in the Registry key will be executed after a user logs into the computer. These programs will be executed under the context of the user and will have the account's associated permissions level.\n\nAdversaries may abuse Active Setup by creating a key under ` HKLM\\SOFTWARE\\Microsoft\\Active Setup\\Installed Components\\` and setting a malicious value for `StubPath`. This value will serve as the program that will be executed when a user logs into the computer.\n\nAdversaries can abuse these components to execute malware, such as remote access tools, to maintain persistence through system reboots. Adversaries may also use Masquerading to make the Registry entries look as if they are associated with legitimate programs.\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.

On Linux, the operating system stores command-line arguments in the process’s stack and passes them to the `main` function as the `argv` array. The first element, `argv[0]`, typically contains the process name or path - by default, the command used to actually start the process (e.g., `cat /etc/passwd`). By default, the Linux `/proc` filesystem uses this value to represent the process name. The `/proc/<PID>/cmdline` file reflects the contents of this memory, and tools like `ps` use it to display process information. Since arguments are stored in user-space memory at launch, this modification can be performed without elevated privileges.\n\nDuring runtime, adversaries can erase the memory used by all command-line arguments for a process, overwriting each argument string with null bytes. This removes evidence of how the process was originally launched. They can then write a spoofed string into the memory region previously occupied by `argv[0]` to mimic a benign command, such as `cat resolv.conf`. The new command-line string is reflected in `/proc/<PID>/cmdline` and displayed by tools like `ps`.\n\n## Reference: ATT&CK AN0159 Analytic 0159\n**ATT&CK AN0159 Analytic 0159 (full record).** Detection of a process or script that accesses a common web service to retrieve content containing obfuscated indicators of a secondary C2 server (dead drop resolver behavior).\n\n**Telemetry.** - auditd:SYSCALL (channel connect)\n- NSM:Flow (channel HTTP/TLS Logs)\n\n## Reference: ATT&CK AN0160 Analytic 0160\n**ATT&CK AN0160 Analytic 0160 (full record).** Detection of a process or script that accesses a common web service to retrieve content containing obfuscated indicators of a secondary C2 server (dead drop resolver behavior).\n\n**Telemetry.** - macos:unifiedlog (channel subsystem: com.apple.network)\n- macos:osquery (channel process_events/socket_events)\n\n## Reference: ATT&CK AN0161 Analytic 0161\n**ATT&CK AN0161 Analytic 0161 (full record).** Detection of a process or script that accesses a common web service to retrieve content containing obfuscated indicators of a secondary C2 server (dead drop resolver behavior).\n\n**Telemetry.** - esxi:vobd (channel Network Events)\n- NSM:Firewall (channel Outbound Connections)\n\n## Reference: ATT&CK AN0162 Analytic 0162\n**ATT&CK AN0162 Analytic 0162 (full record).** Correlate unauthorized or anomalous file modifications, deletions, or metadata changes with suspicious process execution or API calls.

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## Reference: ATT&CK AN0003 Analytic 0003\n**ATT&CK AN0003 Analytic 0003 (full record).** Detects CLI tools (e.g., mosquitto_pub, nc, python scripts) interacting with pub/sub brokers using unusual topic names, high-frequency publication rates, or obfuscated payloads to non-standard hosts.\n\n**Telemetry.** - auditd:SYSCALL (channel execve)\n- NSM:Flow (channel mqtt.log or AMQP custom log)\n\n## Reference: ATT&CK AN0004 Analytic 0004\n**ATT&CK AN0004 Analytic 0004 (full record).** Detects osascript, curl, or custom binaries interacting with XMPP/MQTT brokers in unapproved destinations with encrypted payloads or frequent POST-like requests to broker URIs.\n\n**Telemetry.** - macos:unifiedlog (channel log stream 'eventMessage contains pubsub or broker')\n- macos:osquery (channel socket_events)\n\n## Reference: ATT&CK AN0005 Analytic 0005\n**ATT&CK AN0005 Analytic 0005 (full record).** Detects pub/sub traffic over unusual ports, high-frequency topic publications, and connections to known-bad or dynamic broker endpoints outside allowlisted infrastructure.\n\n**Telemetry.** - NSM:Flow (channel mqtt.log, xmpp.log, amqp.log)\n\n## Reference: ATT&CK AN0006 Analytic 0006\n**ATT&CK AN0006 Analytic 0006 (full record).** Adversary uses built-in tools such as 'net user /add /domain' or PowerShell to create a domain user account.

System software binaries are used by the underlying operating system and users over adb or terminal emulators.\n\nAdversaries may make modifications to client software binaries to carry out malicious tasks when those binaries are executed. For example, malware may come with a pre-compiled malicious binary intended to overwrite the genuine one on the device. Since these binaries may be routinely executed by the system or user, the adversary can leverage this for persistent access to the device.\n\n**Classification.** - Tactics: persistence\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- **System Partition Integrity**: Ensure that Android devices being used include and enable the Verified Boot capability, which cryptographically ensures the integrity of the system partition.\n- **Security Updates**: Install security updates in response to discovered vulnerabilities.\n- **Attestation**: Enable remote attestation capabilities when available (such as Android SafetyNet or Samsung Knox TIMA Attestation) and prohibit devices that fail the attestation from accessing enterprise resources.\n\n**Detection strategies and analytics.** - **Detection of Compromise Client Software Binary**\n  - For Android, detect Compromise Client Software Binary from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

[…]\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. […]"}]}

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## Reference: ATT&CK AN1906 Analytic 1906\n**ATT&CK AN1906 Analytic 1906 (full record).** 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.

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.

Often, these devices are equipped with special, dedicated encryption hardware to greatly increase the speed of the encryption process as well as to prevent malicious tampering. When an adversary takes control of such a device, they may disable the dedicated hardware, for example, through use of Modify System Image, forcing the use of software to perform encryption on general processors. This is typically used in conjunction with attacks to weaken the strength of the cipher in software (e.g., Reduce Key Space).\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n- Sub-technique of: T1600 Weaken Encryption - Adversaries may compromise a network device’s encryption capability in order to bypass encryption that would otherwise protect data communications.\n\n**Detection strategies and analytics.** - **Detection Strategy for Weaken Encryption: Disable Crypto Hardware on Network Devices**\n  - Defenders may observe attempts to disable dedicated crypto hardware on network devices, often visible through anomalous CLI commands, unexpected firmware or configuration updates, and degraded encryption performance. Suspicious indicators include commands that alter hardware acceleration settings (e.g., disabling AES-NI or crypto engines), modification of system image files, or logs showing fallback from hardware to software encryption. Network traffic analysis may also reveal a sudden downgrade in throughput or cipher negotiation behavior consistent with the absence of hardware acceleration.

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. These factors typically include:\n- **Password Policies**: Set 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- **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.

Configuration repositories are used by management systems in order to configure, manage, and control data on remote systems. Configuration repositories may also facilitate remote access and administration of devices.\n\nAdversaries may target these repositories in order to collect large quantities of sensitive system administration data. Data from configuration repositories may be exposed by various protocols and software and can store a wide variety of data, much of which may align with adversary Discovery objectives.\n\n**Classification.** - Tactics: collection\n- Platforms: Network Devices\n\n**Sub-techniques.** - T1602.002 Network Device Configuration Dump: Adversaries may access network configuration files to collect sensitive data about the device and the network.\n- T1602.001 SNMP (MIB Dump): 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\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- **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- **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- **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. […]"}]}

Process injection is a method of executing arbitrary code in the address space of a separate live process.\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- **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\n- **Detection Strategy for /proc Memory Injection on Linux**\n  - Detects adversary behavior where a process enumerates and modifies another process's memory using /proc/[pid]/maps and /proc/[pid]/mem files. This includes identifying gadgets via memory mappings and overwriting process memory via low-level file modification or dd usage. (telemetry: auditd:SYSCALL:open/write to /proc/*/mem or /proc/*/maps, auditd:SYSCALL:execve of dd or sed targeting /proc/*/mem, linux:osquery:/proc/*/maps access)\n\n## Tracked users (groups, malware, tools)\n- KV Botnet Activity (campaign): KV Botnet Activity consisted of exploitation of primarily “end-of-life” small office-home office (SOHO) equipment from manufacturers such as Cisco, NETGEAR, and DrayTek.\n\n## Reference: ATT&CK T1608.007 AI Result Poisoning\n**ATT&CK T1608.007 AI Result Poisoning (full record).** Adversaries may manipulate publicly accessible web content to influence generative AI systems or AI-powered search engines into retrieving, citing, or recommending attacker-controlled information.\n\nUnlike traditional SEO Poisoning, which primarily attempts to influence the ordering of conventional search results, AI Result Poisoning targets systems that synthesize information from multiple sources and provide a direct answer to the user. Adversaries may create malicious or misleading websites, publish fabricated claims, generate supporting articles, or establish multiple apparently independent sources that reinforce the same information. These sources may then be retrieved by AI systems using web search or retrieval-augmented generation and incorporated into generated responses.\n\nAdversaries may use this technique to recommend or link to phishing sites, fraudulent online stores, malicious downloads, impersonation pages, or other attacker-controlled infrastructure. It can also be used to promote misinformation or fabricated claims without requiring access to the underlying AI model, system prompt, or application infrastructure. Because the malicious content can resemble ordinary marketing, editorial, or informational material, traditional prompt injection and malware-focused detections may not identify the activity.\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.

A container administration service such as the Docker daemon, the Kubernetes API server, or the kubelet may allow remote management of containers within an environment.\n\nIn Docker, adversaries may specify an entrypoint during container deployment that executes a script or command, or they may use a command such as `docker exec` to execute a command within a running container. In Kubernetes, if an adversary has sufficient permissions, they may gain remote execution in a container in the cluster via interaction with the Kubernetes API server, the kubelet, or by running a command such as `kubectl exec`.\n\n**Classification.** - Tactics: execution\n- Platforms: Containers\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- **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- **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 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. […]\n\n## Reference: ATT&CK T1610 Deploy Container\n**ATT&CK T1610 Deploy Container (full record).** Adversaries may deploy a container into an environment to facilitate execution or evade defenses. In some cases, adversaries may deploy a new container to execute processes associated with a particular image or deployment, such as processes that execute or download malware. In others, an adversary may deploy a new container configured without network rules, user limitations, etc. to bypass existing defenses within the environment. In Kubernetes environments, an adversary may attempt to deploy a privileged or vulnerable container into a specific node in order to Escape to Host and access other containers running on the node.\n\nContainers can be deployed by various means, such as via Docker's `create` and `start` APIs or via a web application such as the Kubernetes dashboard or Kubeflow. In Kubernetes environments, containers may be deployed through workloads such as ReplicaSets or DaemonSets, which can allow containers to be deployed across multiple nodes. Adversaries may deploy containers based on retrieved or built malicious images or from benign images that download and execute malicious payloads at runtime.\n\n**Classification.** - Tactics: execution\n- Platforms: Containers\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- **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\n## Reference: ATT&CK T1611 Escape to Host\n**ATT&CK T1611 Escape to Host (full record).** Adversaries may break out of a container or virtualized environment to gain access to the underlying host. This can allow an adversary access to other containerized or virtualized resources from the host level or to the host itself. In principle, containerized / virtualized resources should provide a clear separation of application functionality and be isolated from the host environment.\n\nThere are multiple ways an adversary may escape from a container to a host environment. Examples include creating a container configured to mount the host’s filesystem using the bind parameter, which allows the adversary to drop payloads and execute control utilities such as cron on the host; utilizing a privileged container to run commands or load a malicious kernel module on the underlying host; or abusing system calls such as `unshare` and `keyctl` to escalate privileges and steal secrets.\n\nAdditionally, an adversary may be able to exploit a compromised container with a mounted container management socket, such as `docker.sock`, to break out of the container via a Container Administration Command. 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**Classification.** - Tactics: privilege-escalation\n- Platforms: Windows, Linux, Containers, ESXi\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.

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. Execution via proc memory injection may also evade detection from security products since the execution is masked under a legitimate process.\n\n## Reference: ATT&CK DET0306 Detection of Unauthorized Network Firewall Rule Modification\n**Detects.** - T1686.002 Network Device Firewall\n\n**Analytics.** - Analytic 0855: Defender observes configuration changes on firewall/network appliance involving rule creation, modification, or deletion from abnormal management IPs or non-console channels (e.g., remote CLI, API).\n\n## Reference: ATT&CK DET0307 Detect Access to Unsecured Credential Files Across Platforms\n**Detects.** - T1552.001 Credentials In Files\n\n**Analytics.** - Analytic 0856: Correlated file access to insecure credential files (e.g., *.env, *.xml, *.ps1) followed by suspicious process execution or authentication using retrieved credentials.

The knowledge of cloud permission groups can help adversaries determine the particular roles of users and groups within an environment, as well as which users are associated with a particular group.\n\nWith authenticated access there are several tools that can be used to find permissions groups. The `Get-MsolRole` PowerShell cmdlet can be used to obtain roles and permissions groups for Exchange and Office 365 accounts.\n\nAzure CLI (AZ CLI) and the Google Cloud Identity Provider API also provide interfaces to obtain permissions groups. The command `az ad user get-member-groups` will list groups associated to a user account for Azure while the API endpoint `GET lists group resources available to a user for Google.

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\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- **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- **Password Policies**: Set 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- **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## Detection strategies and analytics\n- **Password Guessing via Multi-Source Authentication Failure Correlation**\n  - Series of authentication failures (Event ID 4625) targeting the same or similar user accounts over time from one or more remote IPs (telemetry: WinEventLog:Security:EventCode=4625)\n  - Repeated failed SSH login attempts followed by a possible success from the same remote host (telemetry: linux:syslog:sshd[pid]: Failed password)\n  - Series of failed logins from loginwindow or sshd with repeated usernames or password prompts (telemetry: macos:unifiedlog:authd)\n  - Multiple failed sign-in attempts from external sources across many users followed by success from the same IP (telemetry: azure:signinlogs:Sign-in logs)\n\n## Tracked users (groups, malware, tools)\n- China Chopper (malware): China Chopper is a Web Shell hosted on Web servers to provide access back into an enterprise network that does not rely on an infected system calling back to a remote command and c.\n- VOID MANTICORE (intrusion-set): VOID MANTICORE is a threat group assessed to operate on behalf of Iran’s Ministry of Intelligence and Security (MOIS).\n- Emotet (malware): Emotet is a modular malware variant which is primarily used as a downloader for other malware variants such as TrickBot and IcedID.\n- SpeakUp (malware): SpeakUp is a Trojan backdoor that targets both Linux and OSX devices.

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## Reference: ATT&CK DET0056 Detection Strategy for Subvert Trust Controls via Install Root Certificate.\n**Detects.** - T1553.004 Install Root Certificate\n\n**Analytics.** - Analytic 0153: Detection of unauthorized modifications to Windows root certificate stores by monitoring registry keys, certificate installation processes, and creation of new certificate entries not in baseline trusted lists.\n- Analytic 0154: Detection of unexpected additions or modifications to system-wide certificate stores or execution of commands adding certificates to trusted stores.\n- Analytic 0155: Detection of malicious certificate installation via monitoring execution of the `security add-trusted-cert` command and modifications to system keychains.\n\n## Reference: ATT&CK DET0057 Detect Suspicious Access to securityd Memory for Credential Extraction\n**Detects.** - T1555.002 Securityd Memory\n\n**Analytics.** - Analytic 0156: Detects suspicious memory access attempts targeting the `securityd` process.

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- **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## Detection strategies and analytics\n- **Behavior-chain detection strategy for T1127.002 Trusted Developer Utilities Proxy Execution: ClickOnce (Windows)**\n  - Abuse of ClickOnce applications where rundll32.exe invokes dfshim.dll with ShOpenVerbApplication or dfsvc.exe spawns unexpected child processes or loads unsigned modules.

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 AN0519 Analytic 0519\n**ATT&CK AN0519 Analytic 0519 (full record).** Identify lateral transfer via datastore file uploads or internal scp/ssh sessions that result in new VMX/VMDK or script files.

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.

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.

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.

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. Ptrace system call injection can also be done with `PTRACE_POKETEXT`/`PTRACE_POKEDATA`, which copy data to a specific address in the target processes’ memory (ex: the current address of the next instruction).\n\nPtrace system call injection may not be possible targeting processes that are non-child processes and/or have higher-privileges.\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges.

Local accounts may also be added to network devices, often via common Network Device CLI commands such as `username`, to ESXi servers via `esxcli system account add`, or to Kubernetes clusters using the `kubectl` utility.\n\nAdversaries may also create new local accounts on network firewall management consoles – for example, by exploiting a vulnerable firewall management system, threat actors may be able to establish super-admin accounts that could be used to modify firewall rules and gain further access to the network.\n\nSuch accounts may be used to establish secondary credentialed access that do not require persistent remote access tools to be deployed on the system.\n\n## Reference: ATT&CK AN1810 Analytic 1810\n**ATT&CK AN1810 Analytic 1810 (full record).** Network service scanning can be difficult to detect, and therefore enterprises may be better served focusing on detection at other stages of adversarial behavior.\n\n## Reference: ATT&CK AN1811 Analytic 1811\n**ATT&CK AN1811 Analytic 1811 (full record).** Network service scanning can be difficult to detect, and therefore enterprises may be better served focusing on detection at other stages of adversarial behavior.\n\n## Reference: ATT&CK AN1812 Analytic 1812\n**ATT&CK AN1812 Analytic 1812 (full record).** For Android, detect Abuse Accessibility Features by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

With a sufficient level of access, creating such accounts may be used to establish secondary credentialed access that do not require persistent remote access tools to be deployed on the system.\n\n## Mitigations\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. These factors typically include:\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- **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- **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\n## Detection strategies and analytics\n- **T1136.002 Detection Strategy - Domain Account Creation Across Platforms**\n  - Adversary uses built-in tools such as 'net user /add /domain' or PowerShell to create a domain user account. The behavior chain includes: (1) suspicious process execution on a domain controller followed by (2) user account creation event (Event ID 4720) on the same host. (telemetry: WinEventLog:Security:EventCode=4720, WinEventLog:Sysmon:EventCode=1)\n  - Adversary with access to domain management tools (e.g., `realmd`, `samba-tool`, `ldapmodify`) creates a new domain user via command-line utilities. Behavior chain: LDAP command or script triggers → user entry added in AD via Kerberos/LDAP traffic. (telemetry: auditd:SYSCALL:execution of realmd, samba-tool, or ldapmodify with user-related arguments, NSM:Flow:TGS-REQ and AS-REQ seen for new user shortly after domain-modifying process)\n  - macOS clients joined to AD via LDAP may script account provisioning via `dsconfigad`, `dscl`, or LDAP scripts. Detection occurs when such tools run on a domain-joined system, followed by authentication attempts by a previously unseen account.

Domain accounts are those managed by Active Directory Domain Services where access and permissions are configured across systems and services that are part of that domain. Domain accounts can cover user, administrator, and service accounts.

With a sufficient level of access, creating such accounts may be used to establish secondary credentialed access that do not require persistent remote access tools to be deployed on the system.\n\n## Mitigations\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- **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- **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\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).

Microsoft Exchange transport agents can operate on email messages passing through the transport pipeline to perform various tasks such as filtering spam, filtering malicious attachments, journaling, or adding a corporate signature to the end of all outgoing emails. Transport agents can be written by application developers and then compiled to.NET assemblies that are subsequently registered with the Exchange server. Transport agents will be invoked during a specified stage of email processing and carry out developer defined tasks.\n\nAdversaries may register a malicious transport agent to provide a persistence mechanism in Exchange Server that can be triggered by adversary-specified email events. Though a malicious transport agent may be invoked for all emails passing through the Exchange transport pipeline, the agent can be configured to only carry out specific tasks in response to adversary defined criteria. For example, the transport agent may only carry out an action like copying in-transit attachments and saving them for later exfiltration if the recipient email address matches an entry on a list provided by the adversary.\n\n**Classification.** - Tactics: persistence\n- Platforms: Linux, Windows\n- Sub-technique of: T1505 Server Software Component - Adversaries may abuse legitimate extensible development features of servers to establish persistent access to systems. Enterprise server applications may include features that allow developers to write and install software or scripts to extend the functionality of the main application.\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- **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.

IIS provides several mechanisms to extend the functionality of the web servers. For example, Internet Server Application Programming Interface (ISAPI) extensions and filters can be installed to examine and/or modify incoming and outgoing IIS web requests. Extensions and filters are deployed as DLL files that export three functions: `Get{Extension/Filter}Version`, `Http{Extension/Filter}Proc`, and (optionally) `Terminate{Extension/Filter}`. IIS modules may also be installed to extend IIS web servers.\n\nAdversaries may install malicious ISAPI extensions and filters to observe and/or modify traffic, execute commands on compromised machines, or proxy command and control traffic. ISAPI extensions and filters may have access to all IIS web requests and responses. For example, an adversary may abuse these mechanisms to modify HTTP responses in order to distribute malicious commands/content to previously comprised hosts.\n\nAdversaries may also install malicious IIS modules to observe and/or modify traffic. IIS 7.0 introduced modules that provide the same unrestricted access to HTTP requests and responses as ISAPI extensions and filters. IIS modules can be written as a DLL that exports `RegisterModule`, or as a.NET application that interfaces with ASP.NET APIs to access IIS HTTP requests.\n\n**Classification.** - Tactics: persistence\n- Platforms: Windows\n- Sub-technique of: T1505 Server Software Component - Adversaries may abuse legitimate extensible development features of servers to establish persistent access to systems.

[…]\n\n## Reference: ATT&CK T1505.005 Terminal Services DLL\n**ATT&CK T1505.005 Terminal Services DLL (full record).** Adversaries may abuse components of Terminal Services to enable persistent access to systems. Microsoft Terminal Services, renamed to Remote Desktop Services in some Windows Server OSs as of 2022, enable remote terminal connections to hosts. Terminal Services allows servers to transmit a full, interactive, graphical user interface to clients via RDP.\n\nWindows Services that are run as a \"generic\" process (ex: `svchost.exe`) load the service's DLL file, the location of which is stored in a Registry entry named `ServiceDll`. The `termsrv.dll` file, typically stored in `%SystemRoot%\\System32\\`, is the default `ServiceDll` value for Terminal Services in `HKLM\\System\\CurrentControlSet\\services\\TermService\\Parameters\\`.\n\nAdversaries may modify and/or replace the Terminal Services DLL to enable persistent access to victimized hosts. Modifications to this DLL could be done to execute arbitrary payloads (while also potentially preserving normal `termsrv.dll` functionality) as well as to simply enable abusable features of Terminal Services. For example, an adversary may enable features such as concurrent Remote Desktop Protocol sessions by either patching the `termsrv.dll` file or modifying the `ServiceDll` value to point to a DLL that provides increased RDP functionality. On a non-server Windows OS this increased functionality may also enable an adversary to avoid Terminal Services prompts that warn/log out users of a system when a new RDP session is created.\n\n**Classification.** - Tactics: persistence\n- Platforms: Windows\n- Sub-technique of: T1505 Server Software Component - Adversaries may abuse legitimate extensible development features of servers to establish persistent access to systems.

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\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- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\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. 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\n## Detection strategies and analytics\n- **User Execution – Malicious Image (containers & IaaS) – pull/run → start → anomalous behavior (T1204.003)**\n  - CONTAINERS (Docker/K8s/containerd): A user pulls an untrusted image from a public/unknown registry and then creates/starts a container from that image.

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 purchase or steal code signing certificates for use in operations. The purchase of code signing certificates may be done using a front organization or using information stolen from a previously compromised entity that allows the adversary to validate to a certificate provider as that entity. Adversaries may also steal code signing materials directly from a compromised third-party.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1588 Obtain Capabilities - Adversaries may buy and/or steal capabilities that can be used during targeting.

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 Code Signing Certificates**\n  - Consider analyzing code signing certificates for features that may be associated with the adversary and/or their developers, such as the thumbprint, algorithm used, validity period, common name, and certificate authority. Malware repositories can also be used to identify additional samples associated with the adversary and identify patterns an adversary has used in procuring code signing certificates. […]\n\n## Reference: ATT&CK T1588.004 Digital Certificates\n**ATT&CK T1588.004 Digital Certificates (full record).** Adversaries may buy and/or steal SSL/TLS certificates that can be used during targeting. SSL/TLS certificates are designed to instill trust. They 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 with its owner.\n\nAdversaries may purchase or steal SSL/TLS certificates to further their operations, such as encrypting C2 traffic (ex: Asymmetric Cryptography with Web Protocols) or even enabling Adversary-in-the-Middle if the certificate is trusted or otherwise added to the root of trust (i.e. Install Root Certificate). The purchase of digital certificates may be done using a front organization or using information stolen from a previously compromised entity that allows the adversary to validate to a certificate provider as that entity. Adversaries may also steal certificate materials directly from a compromised third-party, including from certificate authorities. Adversaries may register or hijack domains that they will later purchase an SSL/TLS certificate for.\n\nCertificate authorities exist that allow adversaries to acquire SSL/TLS certificates, such as domain validation certificates, for free.\n\nAfter obtaining a digital certificate, an adversary may then install that certificate (see Install Digital Certificate) on infrastructure under their control.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1588 Obtain Capabilities - Adversaries may buy and/or steal capabilities that can be used during targeting.

An exploit takes advantage of a bug or vulnerability in order to cause unintended or unanticipated behavior to occur on computer hardware or software. Rather than developing their own exploits, an adversary may find/modify exploits from online or purchase them from exploit vendors.\n\nIn addition to downloading free exploits from the internet, adversaries may purchase exploits from third-party entities. Third-party entities can include technology companies that specialize in exploit development, criminal marketplaces (including exploit kits), or from individuals. In addition to purchasing exploits, adversaries may steal and repurpose exploits from third-party entities (including other adversaries).\n\nAn adversary may monitor exploit provider forums to understand the state of existing, as well as newly discovered, exploits. There is usually a delay between when an exploit is discovered and when it is made public. An adversary may target the systems of those known to conduct exploit research and development in order to gain that knowledge for use during a subsequent operation.\n\nAdversaries may use exploits during various phases of the adversary lifecycle (i.e. Exploit Public-Facing Application, Exploitation for Client Execution, Exploitation for Privilege Escalation, Exploitation for Stealth, Exploitation for Credential Access, Exploitation of Remote Services, and Application or System Exploitation).\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1588 Obtain Capabilities - Adversaries may buy and/or steal capabilities that can be used during targeting.

Timestomping is a technique that modifies the timestamps of a file (the modify, access, create, and change times), often to mimic files that are in the same folder and blend malicious files with legitimate files.\n\nIn Windows systems, both the `$STANDARD_INFORMATION` (`$SI`) and `$FILE_NAME` (`$FN`) attributes record times in a Master File Table (MFT) file. `$SI` (dates/time stamps) is displayed to the end user, including in the File System view, while `$FN` is dealt with by the kernel.\n\nModifying the `$SI` attribute is the most common method of timestomping because it can be modified at the user level using API calls. `$FN` timestomping, however, typically requires interacting with the system kernel or moving or renaming a file.\n\nAdversaries modify timestamps on files so that they do not appear conspicuous to forensic investigators or file analysis tools. In order to evade detections that rely on identifying discrepancies between the `$SI` and `$FN` attributes, adversaries may also engage in “double timestomping” by modifying times on both attributes simultaneously.\n\nIn Linux systems and on ESXi servers, threat actors may attempt to perform timestomping using commands such as `touch -a -m -t <timestamp> <filename>` (which sets access and modification times to a specific value) or `touch -r <filename> <filename>` (which sets access and modification times to match those of another file).\n\nTimestomping may be used along with file name Masquerading to hide malware and tools.\n\n**Classification.** - Tactics: stealth\n- Platforms: ESXi, Linux, macOS, Windows\n- Sub-technique of: T1070 Indicator Removal - Adversaries may selectively delete or modify artifacts generated to reduce indications of their presence and blend in with legitimate activity.

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. Adversaries may delete or modify this data to conceal indicators and/or impede defensive analysis.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows, Network Devices\n- Sub-technique of: T1070 Indicator Removal - Adversaries may selectively delete or modify artifacts generated to reduce indications of their presence and blend in with legitimate activity.\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.

[…]\n\n## Reference: ATT&CK T1070.008 Clear Mailbox Data\n**ATT&CK T1070.008 Clear Mailbox Data (full record).** Adversaries may modify mail and mail application data to remove evidence of their activity. Email applications allow users and other programs to export and delete mailbox data via command line tools or use of APIs. Mail application data can be emails, email metadata, or logs generated by the application or operating system, such as export requests.\n\nAdversaries may manipulate emails and mailbox data to remove logs, artifacts, and metadata, such as evidence of Phishing/Internal Spearphishing, Email Collection, Mail Protocols for command and control, or email-based exfiltration such as Exfiltration Over Alternative Protocol. For example, to remove evidence on Exchange servers adversaries have used the `ExchangePowerShell` PowerShell module, including `Remove-MailboxExportRequest` to remove evidence of mailbox exports. On Linux and macOS, adversaries may also delete emails through a command line utility called `mail` or use AppleScript to interact with APIs on macOS.\n\nAdversaries may also remove emails and metadata/headers indicative of spam or suspicious activity (for example, through the use of organization-wide transport rules) to reduce the likelihood of malicious emails being detected by security products.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Office Suite, Windows\n- Sub-technique of: T1070 Indicator Removal - Adversaries may selectively delete or modify artifacts generated to reduce indications of their presence and blend in with legitimate activity.\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- **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.

Users may be subjected to social engineering to get them to copy and paste code directly into a Command and Scripting Interpreter. 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. When a user attempts to open an attachment, they may be presented with a fake error and offered a malicious command to paste as a solution, consistent with the \"ClickFix\" strategy.\n\nTricking a user into executing a command themselves may help to bypass email filtering, browser sandboxing, or other mitigations designed to protect users against malicious downloaded files.\n\n## Reference: ATT&CK DET0726 Detection of Wireless Compromise\n**Detects.** -

To guarantee this security, chaotic systems have many advantages as unpredictability or disorder-like, and they are especially used when complex sequences are required [ 5, 8, 11 ]. This is why chaotic systems are frequently used to design new pseudo-random number generators (PRNGs) [ 5, 9 ].Following this approach, we have previously proposed a PRNG based on chaotic iterations. A short overview of our recent researches in this field is given hereafter.\n\nIn Ref. [3], it is proven that chaotic iterations (CIs), a suitable tool for fast computing iterative algorithms, satisfies the topological chaos property, as defined by Devaney [6]. The chaotic behavior of CIs is used in [1], to obtain an unpredictable PRNG that depends on two logistic maps. The resulted PRNG shows better statistical properties than each individual component alone. Additionally, various chaos properties have been established. These chaos properties, inherited from CIs, are not possessed by the two inputted generators. We have shown that, in addition of being chaotic, this generator can pass the NIST battery of tests, widely considered as a comprehensive and stringent battery of tests for cryptographic applications [13]. Then we have achieved to improve the speed of the former generator in [ 2, 4 ], by using ISAAC and XORshift instead of the two logistic maps. These generators can pass the batteries DieHARD [10] and TestU01 [14].\n\nIn these previous researches, the iteration function of CIs was always the vectorial Boolean negation. We propose now to enlarge the set of iteration functions such that the associated CI-based generator is both chaotic and random-like. The well-known NIST and DieHARD tests are finally used to evaluate the statistical behavior of this new family of generators.\n\nThe rest of this paper is organized as follows. In the next section, some basic definitions concerning CIs and our PRNG are recalled. In Section III is explained how it is possible to change the iteration function of the generator without losing the good properties of our PRNG.

During the WBAN deployment, the administrator loads these reference frames with identical dummy values at both the WCC and the monitoring station data receiver. When the receiver successfully receives the sent data frame, it sends an acknowledgement (ACK) to the WCC, along with the sequence number. Then, the receiver waits for one more reception, and updates its reference frame list. Upon reception of the ACK, the WCC proceeds to update its reference frame list. The reference frame list is updated as follows. The sender (or, receiver) checks for the oldest reference frame in its list. This is assumed to be the frame with the oldest sequence number. The system then replaces this reference frame with the acknowledged frame.\n\n**3.2.2   Sender Authentication and Tone.** Each encrypted data frame that is transmitted is appended with the sequence number of the reference frame used for generating the key, the field number in this reference frame whose value is used as the seed, a “Tone” value, and a sender authentication code.\n\nFigure 5. Structure of the transmitted frame The transmitted frame is as illustrated in figure 5. The tone is a random number between 1 and 5, generated for each data frame. To generate the sender authentication code, the reference frame that was chosen to generate the encryption key is hashed the number of times indicated by the Tone value of that frame. This is analogous to generating a digital signature of the sender on the fly for each transmitted frame. The receiver repeats this process by retrieving the reference\n\n104\n\nframe pointed by the reference-frame-sequence-number that was received as part of the transmitted message to authenticate the sender. The value of the tone has a minimum value of 1so as to ensure that the reference frame is hashed at least once, and has a maximum value of 5 to ensure that the hashing process does not become increasingly computationally expensive.

On the other hand, it is necessary to increase the key sizes gradually for effective countermeasures against new cryptanalytic insights to maintain a comfortable margin of security. This is based on explicitly formulated parameters and existing cryptosystems in symmetric cryptosystems, RSA, and discrete logarithm based cryptosystems [13]. This key size issue is addressed by designing optimal bits length integrated key scheme for commercial security. III. ANONYMOUS GEOGRAPHIC PARAMETERS Each radio or node has unique geographic location and RTT assets which can be deployed as anonymous geographic parameters for strict friendliness. The location information includes radial or scalar Euclidean distance and angle between the sender and receiver which are computed from the average time difference of TOA (Time of Arrival) and TOD (Time of Departure) and the angular bearing by AOA (Angle of Arrival) for ith number of packets. The radial distance (DRadial) between sender and receiver is computed as the average time difference of arrival time of preamble packet at receiver and departure time of response from receiver to sender as follows:.\n\n1 1 2 1\n\n[ { }] (1)\n\n(2) n Radial i i i D c ToD ToA n RTT T T = = − = − ∑\n\nwhere, Speed of light (c) = 3×108 m/ sec\n\nTransmission time from sender to receiver (T1) Responding time from receiver to sender (T2)\n\nIn AOA, directional antenna-arrays are used to estimate the direction of arrival (θ) of the signal of interest and a single AOA measurement constrains the source along a line. The precision of AOA depends upon the line of sight between sender and receiver. Additionally, RTT (Round Trip Time) is computed as the total time elapsed between the transmission and the reception of the acknowledgement for ith number of packet. This round trip time includes the propagation delay of the packet traveling in both directions and processing delay.

Moreover, as Bluetooth networks are formed by the radio links, there are also additional security aspects whose impact is yet not well understood. In this paper, we propose a novel Man-In- The-Middle (MITM) attack against Bluetooth enabled mobile phone that support Simple Secure Pairing( SSP). From the literature it was proved that the SSP association models such as Numeric comparison, Just works and passkey Entry are not more secure. Here we propose the Out Of Band (OOB) channeling with enhanced security than the previous methods.\n\nKeywords- Authentication, Bluetooth, Man-In-The- Middle attack, Secure Simple Pairing, Out Of Band channeling.\n\n**I. INTRODUCTION.** Bluetooth is an open standard for short-range radio frequency (RF) communication. Bluetooth standard specifies wireless operation in the 2.4 GHz–2.4835 GHz ISM frequency band and supports data rates up to 720 Kbps. Bluetooth uses a frequency-hopping spreadspectrum (FHSS) technology to solve interference problems. The FHSS scheme uses 79 different radio channels by changing frequency about 1,600 times per second. This allows users to form ad-hoc networks between a wide variety of devices to transfer voice and data. Bluetooth eliminate wires and cables between both\n\nstationary and mobile devices. Bluetooth is a low-cost, low-power technology that provides a mechanism for creating small wireless networks on an ad-hoc basis, known as piconets. A piconet is composed of two or more Bluetooth devices in close physical proximity that operate on the same channel using the same frequency hopping sequence. […]"}]}

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.

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.

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.

Adversaries may also utilize this technique to perform SID-History Injection and/or manipulate AD objects (such as accounts, access control lists, schemas) to establish backdoors for Persistence.\n\n## Reference: ATT&CK AN0016 Analytic 0016\n**ATT&CK AN0016 Analytic 0016 (full record).** Adversary uses nltest, PowerShell, or Win32/.NET API to enumerate domain trust relationships (via DSEnumerateDomainTrusts, GetAllTrustRelationships, or LDAP queries), followed by discovery or authentication staging.\n\n**Telemetry.** - WinEventLog:Sysmon (channel EventCode=1)\n- WinEventLog:Sysmon (channel EventCode=7)\n- WinEventLog:Sysmon (channel EventCode=10)\n- WinEventLog:PowerShell (channel Get-ADTrust|GetAllTrustRelationships)\n- WinEventLog:Security (channel EventCode=4662)\n\n## Reference: ATT&CK AN0017 Analytic 0017\n**ATT&CK AN0017 Analytic 0017 (full record).** Cloud login from atypical geolocation or user-agent string, followed by resource enumeration or infrastructure manipulation using cloud CLI/API\n\n**Telemetry.** - AWS:CloudTrail (channel ConsoleLogin, AssumeRole, ListResources)\n- gcp:audit (channel None)\n\n## Reference: ATT&CK AN0018 Analytic 0018\n**ATT&CK AN0018 Analytic 0018 (full record).** Federated login using SSO or OAuth grant to cloud control plane, followed by directory or permissions enumeration\n\n**Telemetry.** - Okta:SystemLog (channel user.authentication.sso, app.oauth.grant)\n\n## Reference: ATT&CK AN0019 Analytic 0019\n**ATT&CK AN0019 Analytic 0019 (full record).** Login to M365 or Google Workspace from CLI tools or unexpected source IPs, followed by mailbox or document access\n\n**Telemetry.** - m365:unified (channel FileAccessed, MailboxAccessed)\n- m365:unified (channel UserLoggedIn)\n\n## Reference: ATT&CK AN0020 Analytic 0020\n**ATT&CK AN0020 Analytic 0020 (full record).** Remote access to third-party SaaS with OAuth or API tokens post-initial compromise, followed by sensitive data access or configuration changes\n\n**Telemetry.** - saas:auth (channel LoginSuccess, APIKeyUse, AdminAction)\n\n## Reference: ATT&CK AN0021 Analytic 0021\n**ATT&CK AN0021 Analytic 0021 (full record).** Adversary manipulates dependencies/dev tools used by developers or CI: a package manager (npm/yarn/pnpm, pip/pipenv, nuget/dotnet, chocolatey/winget, maven/gradle) or a compiler/IDE downloads or restores content; files are written under project paths and execution paths (node_modules, packages,.nuget,.gradle,.m2, %AppData%\\npm, %UserProfile%\\.cargo\\bin, temp build dirs).

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 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\n## Detection strategies and analytics\n- **Detection Strategy for Exploitation for Stealth**\n  - Detects exploitation attempts targeting defensive security software or OS services. Defender observation includes abnormal process behavior (e.g., AV or EDR crashing unexpectedly), unsigned/untrusted modules loaded into defensive processes, or privilege escalation from security agent services. Multi-event correlation ties exploitation attempts to subsequent evasive behavior like service termination or missing logs. (telemetry: WinEventLog:Security:EventCode=4688, WinEventLog:Sysmon:EventCode=7)\n  - Detects kernelor user-space exploitation attempts targeting auditd, AV daemons, or security monitoring agents. Defender observation includes unexpected segfaults, privilege escalation attempts from low-privileged processes, or modifications to security binaries. Correlates exploitation attempts with subsequent gaps in logging or terminated processes. (telemetry: auditd:SYSCALL:execve: Execution of suspicious exploit binaries targeting security daemons, linux:syslog:Segfaults, kernel oops, or crashes in security software processes)\n  - Detects exploitation of macOS security and integrity services, such as Gatekeeper, XProtect, or EDR agents. Defender observations include unsigned processes attempting privileged operations, abnormal termination of security daemons, or modification of system integrity logs. (telemetry: macos:unifiedlog:Abnormal terminations of com.apple.security.* or 3rd-party security daemons, macos:osquery:execve: Unsigned or unnotarized processes launched with high privileges)\n  - Detects exploitation of IaaS cloud security boundaries to evade defense controls. Defender perspective includes anomalous API calls that bypass audit logging, disable monitoring, or manipulate guardrails (e.g., CloudTrail tampering).

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**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.

Establishing a persona may require development of additional documentation to make them seem real. This could include filling out profile information, developing social networks, or incorporating photos.\n\nEstablishing accounts can also include the creation of accounts with email providers, which may be directly leveraged for Phishing for Information or Phishing.

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.

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. Brute forcing passwords can take place via interaction with a service that will check the validity of those credentials or offline against previously acquired credential data, such as password hashes.\n\nBrute forcing credentials may take place at various points during a breach. For example, adversaries may attempt to brute force access to Valid Accounts within a victim environment leveraging knowledge gathered from other post-compromise behaviors such as OS Credential Dumping, Account Discovery, or Password Policy Discovery. Adversaries may also combine brute forcing activity with behaviors such as External Remote Services as part of Initial Access.\n\nIf an adversary guesses the correct password but fails to login to a compromised account due to location-based conditional access policies, they may change their infrastructure until they match the victim’s location and therefore bypass those policies.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1110.004 Credential Stuffing: Adversaries may use credentials obtained from breach dumps of unrelated accounts to gain access to target accounts through credential overlap.\n- T1110.002 Password Cracking: Adversaries may use password cracking to attempt to recover usable credentials, such as plaintext passwords, when credential material such as password hashes are obtained.\n- T1110.001 Password Guessing: Adversaries with no prior knowledge of legitimate credentials within the system or environment may guess passwords to attempt access to accounts.\n- T1110.003 Password Spraying: Adversaries may use a single or small list of commonly used passwords against many different accounts to attempt to acquire valid account credentials.

Without knowledge of the password for an account, an adversary may opt to systematically guess the password using a repetitive or iterative mechanism. An adversary may guess login credentials without prior knowledge of system or environment passwords during an operation by using a list of common passwords. Password guessing may or may not take into account the target's policies on password complexity or use policies that may lock accounts out after a number of failed attempts.\n\nGuessing passwords can be 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 guessing passwords. 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* SNMP (161/UDP and 162/TCP/UDP)\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.. Further, adversaries may abuse network device interfaces (such as `wlanAPI`) to brute force accessible wifi-router(s) via wireless authentication protocols.\n\nIn default environments, LDAP and Kerberos connection attempts are less likely to trigger events over SMB, which creates Windows \"logon failure\" event ID 4625.

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. 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.** - **Password Policies**: Set 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- **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.

Code repositories are tools/services that store source code and automate software builds. They may be hosted internally or privately on third party sites such as Github, GitLab, SourceForge, and BitBucket. Users typically interact with code repositories through a web application or command-line utilities such as git.\n\nOnce adversaries gain access to a victim network or a private code repository, they may collect sensitive information such as proprietary source code or Unsecured Credentials contained within software's source code. Having access to software's source code may allow adversaries to develop Exploits, while credentials may provide access to additional resources using Valid Accounts.\n\n**Note:** This is distinct from Code Repositories, which focuses on conducting Reconnaissance via public code repositories.\n\n## Reference: ATT&CK T1201 Password Policy Discovery\n**ATT&CK T1201 Password Policy Discovery (full record).** Adversaries may attempt to access detailed information about the password policy used within an enterprise network or cloud environment. Password policies are a way to enforce complex passwords that are difficult to guess or crack through Brute Force. This information may help the adversary to create a list of common passwords and launch dictionary and/or brute force attacks which adheres to the policy (e.g. if the minimum password length should be 8, then not trying passwords such as 'pass123'; not checking for more than 3-4 passwords per account if the lockout is set to 6 as to not lock out accounts).\n\nPassword policies can be set and discovered on Windows, Linux, and macOS systems via various command shell utilities such as `net accounts (/domain)`, `Get-ADDefaultDomainPasswordPolicy`, `chage -l <username>`, `cat /etc/pam.d/common-password`, and `pwpolicy getaccountpolicies`. Adversaries may also leverage a Network Device CLI on network devices to discover password policy information (e.g. `show aaa`, `show aaa common-criteria policy all`).\n\nPassword policies can be discovered in cloud environments using available APIs such as `GetAccountPasswordPolicy` in AWS.\n\n**Classification.** - Tactics: discovery\n- Platforms: Windows, Linux, macOS, IaaS, Network Devices, Identity Provider, SaaS, Office Suite\n\n**Mitigations.** - **Password Policies**: Set 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. […]\n\n## Reference: ATT&CK T1202 Indirect Command Execution\n**ATT&CK T1202 Indirect Command Execution (full record).** Adversaries may abuse utilities that allow for command execution to bypass security restrictions that limit the use of command-line interpreters. Various Windows utilities may be used to execute commands, possibly without invoking cmd. For example, Forfiles, the Program Compatibility Assistant (`pcalua.exe`), components of the Windows Subsystem for Linux (WSL), `Scriptrunner.exe`, as well as other utilities may invoke the execution of programs and commands from a Command and Scripting Interpreter, Run window, or via scripts. Adversaries may also abuse the `ssh.exe` binary to execute malicious commands via the `ProxyCommand` and `LocalCommand` options, which can be invoked via the `-o` flag or by modifying the SSH config file.\n\nAdversaries may abuse these features for Stealth, specifically to perform arbitrary execution while subverting detections and/or mitigation controls (such as Group Policy) that limit/prevent the usage of cmd or file extensions more commonly associated with malicious payloads.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n\n**Detection strategies and analytics.** - **Indirect Command Execution – Windows utility abuse behavior chain**\n  - Cause→effect chain: (1) A user or service launches an indirection utility (e.g., forfiles.exe, pcalua.exe, wsl.exe, scriptrunner.exe, ssh.exe with -o ProxyCommand/LocalCommand). (2) That utility spawns a secondary program/command (PowerShell, cmd, msiexec, regsvr32, curl, arbitrary EXE) and/or opens outbound network connections. (3) Optional precursor modification of SSH config to persist LocalCommand/ProxyCommand. Correlate process creation, command/script content, file access to %USERPROFILE%\\.ssh\\config, and network connections from the utility or its child. […]\n\n## Reference: ATT&CK T1203 Exploitation for Client Execution\n**ATT&CK T1203 Exploitation for Client Execution (full record).** Adversaries may exploit software vulnerabilities in client applications to execute code. Vulnerabilities can exist in software due to unsecure coding practices that can lead to unanticipated behavior. Adversaries can 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\nSeveral types exist:\n\n**Browser-based Exploitation.** Web browsers are a common target through Drive-by Compromise and Spearphishing Link. Endpoint systems may be compromised through normal web browsing or from certain users being targeted by links in spearphishing emails to adversary controlled sites used to exploit the web browser. These often do not require an action by the user for the exploit to be executed.\n\n**Office Applications.** Common office and productivity applications such as Microsoft Office are also targeted through Phishing. Malicious files will be transmitted directly as attachments or through links to download them. These require the user to open the document or file for the exploit to run.\n\n**Common Third-party Applications.** Other applications that are commonly seen or are part of the software deployed in a target network may also be used for exploitation. Applications such as Adobe Reader and Flash, which are common in enterprise environments, have been routinely targeted by adversaries attempting to gain access to systems. Depending on the software and nature of the vulnerability, some may be exploited in the browser or require the user to open a file. For instance, some Flash exploits have been delivered as objects within Microsoft Office documents.\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, macOS, Windows\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\n## Reference: ATT&CK T1204 User Execution\n**ATT&CK T1204 User Execution (full record).** 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. These user actions will typically be observed as follow-on behavior from forms of Phishing.\n\nWhile User Execution frequently occurs shortly after Initial Access it may occur at other phases of an intrusion, such as when an adversary places a file in a shared directory or on a user's desktop hoping that a user will click on it. This activity may also be seen shortly after Internal Spearphishing.\n\nAdversaries may also deceive users into performing actions such as:\n\n* Enabling Remote Access Tools, allowing direct control of the system to the adversary\n* Running malicious JavaScript in their browser, allowing adversaries to Steal Web Session Cookies\n* Downloading and executing malware for User Execution\n* Coerceing users to copy, paste, and execute malicious code manually\n\nFor example, tech support scams can be facilitated through Phishing, vishing, or various forms of user interaction. Adversaries can use a combination of these methods, such as spoofing and promoting toll-free numbers or call centers that are used to direct victims to malicious websites, to deliver and execute payloads containing malware or Remote Access Tools.\n\n**Classification.** - Tactics: execution\n- Platforms: Linux, Windows, macOS, IaaS, Containers\n\n**Sub-techniques.** - T1204.005 Malicious Library: Adversaries may rely on a user installing a malicious library to facilitate execution.\n- T1204.002 Malicious File: An adversary may rely upon a user opening a malicious file in order to gain execution. Users may be subjected to social engineering to get them to open a file that will lead to code execution.\n- T1204.003 Malicious Image: Adversaries may rely on a user running a malicious image to facilitate execution.\n- T1204.001 Malicious Link: An adversary may rely upon a user clicking a malicious link in order to gain execution. […]\n\n## Reference: ATT&CK T1204.001 Malicious Link\n**ATT&CK T1204.001 Malicious Link (full record).** An adversary may rely upon a user clicking a malicious link in order to gain execution. Users may be subjected to social engineering to get them to click on a link that will lead to code execution. This user action will typically be observed as follow-on behavior from Spearphishing Link. Clicking on a link may also lead to other execution techniques such as exploitation of a browser or application vulnerability via Exploitation for Client Execution. Links may also lead users to download files that require execution via Malicious File.\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.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\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. 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- **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. […]"}]}

Behavior is detected through command-line process lineage, child process spawning, and unsigned payload execution from signed parent.

Several Microsoft signed scripts that have been downloaded from Microsoft or are default on Windows installations can be used to proxy execution of other files.

Msiexec.exe is the command-line utility for the Windows Installer and is thus commonly associated with executing installation packages (.msi). The Msiexec.exe binary may also be digitally signed by Microsoft.\n\nAdversaries may abuse msiexec.exe to launch local or network accessible MSI files. Msiexec.exe can also execute DLLs. Since it may be signed and native on Windows systems, msiexec.exe can be used to bypass application control solutions that do not account for its potential abuse. Msiexec.exe execution may also be elevated to SYSTEM privileges if the `AlwaysInstallElevated` policy is enabled.\n\n## Reference: ATT&CK T1133 External Remote Services\n**ATT&CK T1133 External Remote Services (full record).** Adversaries may leverage external-facing remote services to initially access and/or persist within a network. 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. The Windows security identifier (SID) is a unique value that identifies a user or group account. […]\n\n## Reference: ATT&CK T1134.001 Token Impersonation/Theft\n**ATT&CK T1134.001 Token Impersonation/Theft (full record).** Adversaries may duplicate then impersonate another user's existing token 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. Windows uses access tokens to determine the ownership of a running process.\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- **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 T1134.002 Create Process with Token\n**ATT&CK T1134.002 Create Process with Token (full record).** Adversaries may create a new process with an existing token to escalate privileges 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.

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. […]\n\n## Reference: ATT&CK T1134.003 Make and Impersonate Token\n**ATT&CK T1134.003 Make and Impersonate Token (full record).** Adversaries may make new tokens and impersonate users to escalate privileges 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.

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.

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.

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. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation.\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- **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 T1036.011 Overwrite Process Arguments\n**ATT&CK T1036.011 Overwrite Process Arguments (full record).** Adversaries may modify a process's in-memory arguments to change its name in order to appear as a legitimate or benign process. On Linux, the operating system stores command-line arguments in the process’s stack and passes them to the `main` function as the `argv` array. The first element, `argv[0]`, typically contains the process name or path - by default, the command used to actually start the process (e.g., `cat /etc/passwd`). By default, the Linux `/proc` filesystem uses this value to represent the process name. The `/proc/<PID>/cmdline` file reflects the contents of this memory, and tools like `ps` use it to display process information. Since arguments are stored in user-space memory at launch, this modification can be performed without elevated privileges.\n\nDuring runtime, adversaries can erase the memory used by all command-line arguments for a process, overwriting each argument string with null bytes. This removes evidence of how the process was originally launched. They can then write a spoofed string into the memory region previously occupied by `argv[0]` to mimic a benign command, such as `cat resolv.conf`. The new command-line string is reflected in `/proc/<PID>/cmdline` and displayed by tools like `ps`.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux\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. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation.\n\n**Detection strategies and analytics.** - **Detection Strategy for Overwritten Process Arguments Masquerading**\n  - Detects adversary behavior where the command-line arguments of a running process are overwritten in memory to spoof the process name, typically replacing it with a benign or misleading string. […]\n\n## Reference: ATT&CK T1036.012 Browser Fingerprint\n**ATT&CK T1036.012 Browser Fingerprint (full record).** Adversaries may attempt to blend in with legitimate traffic by spoofing browser and system attributes like operating system, system language, platform, user-agent string, resolution, time zone, etc. The HTTP User-Agent request header is a string that lets servers and network peers identify the application, operating system, vendor, and/or version of the requesting user agent.\n\nAdversaries may gather this information through System Information Discovery or by users navigating to adversary-controlled websites, and then use that information to craft their web traffic to evade defenses.\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. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation.\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\n**Detection strategies and analytics.** - **Detection of Spoofed User-Agent**\n  - Process execution without GUI context (e.g., powershell.exe, wscript.exe) generates HTTP traffic with a spoofed User-Agent mimicking a legitimate browser. No corresponding UI application (e.g., msedge.exe) is active or in parent lineage. The User-Agent deviates from known enterprise baselines or contains spoofed platform indicators. User-Agent strings can be gathered with API calls such as `ShellExecuteW` to open the default browser on a socket to receive an HTTP reply, or by hard coding the User-Agent string for a specific browser. […]\n\n## Reference: ATT&CK T1037 Boot or Logon Initialization Scripts\n**ATT&CK T1037 Boot or Logon Initialization Scripts (full record).** Adversaries may use scripts automatically executed at boot or logon initialization to establish persistence. Initialization scripts can be used to perform administrative functions, which may often execute other programs or send information to an internal logging server. These scripts can vary based on operating system and whether applied locally or remotely.\n\nAdversaries may use these scripts to maintain persistence on a single system. Depending on the access configuration of the logon scripts, either local credentials or an administrator account may be necessary.\n\nAn adversary may also be able to escalate their privileges since some boot or logon initialization scripts run with higher privileges.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n\n**Sub-techniques.** - T1037.004 RC Scripts: Adversaries may establish persistence by modifying RC scripts, which are executed during a Unix-like system’s startup.\n- T1037.001 Logon Script (Windows): Adversaries may use Windows logon scripts automatically executed at logon initialization to establish persistence.\n- T1037.003 Network Logon Script: Adversaries may use network logon scripts automatically executed at logon initialization to establish persistence.\n- T1037.005 Startup Items: Adversaries may use startup items automatically executed at boot initialization to establish persistence.\n- T1037.002 Login Hook: Adversaries may use a Login Hook to establish persistence executed upon user logon. A login hook is a plist file that points to a specific script to execute with root privileges upon user 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. […]"}]}

Examples of audio information adversaries may target include user conversations, surroundings, phone calls, or other sensitive information.\n\nAndroid and iOS, by default, require that applications request device microphone access from the user.\n\nOn Android devices, applications must hold the `RECORD_AUDIO` permission to access the microphone or the `CAPTURE_AUDIO_OUTPUT` permission to access audio output. 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## Reference: ATT&CK DC0105 Group Metadata\n**ATT&CK DC0105 Group Metadata (full record).** Group metadata includes attributes like name, permissions, purpose, and associated user accounts or roles, which adversaries may exploit for privilege escalation.

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 T1526 Cloud Service Discovery\n**ATT&CK T1526 Cloud Service Discovery (full record).** An adversary may attempt to enumerate the cloud services running on a system after gaining access. These methods can differ from platform-as-a-service (PaaS), to infrastructure-as-a-service (IaaS), or software-as-a-service (SaaS). Many services exist throughout the various cloud providers and can include Continuous Integration and Continuous Delivery (CI/CD), Lambda Functions, Entra ID, etc. They may also include security services, such as AWS GuardDuty and Microsoft Defender for Cloud, and logging services, such as AWS CloudTrail and Google Cloud Audit Logs.\n\nAdversaries may attempt to discover information about the services enabled throughout the environment. Azure tools and APIs, such as the Microsoft Graph API and Azure Resource Manager API, can enumerate resources and services, including applications, management groups, resources and policy definitions, and their relationships that are accessible by an identity.\n\nFor example, Stormspotter is an open source tool for enumerating and constructing a graph for Azure resources and services, and Pacu is an open source AWS exploitation framework that supports several methods for discovering cloud services.\n\nAdversaries may use the information gained to shape follow-on behaviors, such as targeting data or credentials from enumerated services or evading identified defenses through Disable or Modify Tools or Disable or Modify Cloud Log.\n\n**Classification.** - Tactics: discovery\n- Platforms: IaaS, Identity Provider, Office Suite, SaaS\n\n**Detection strategies and analytics.** - **Detection Strategy for Cloud Service Discovery**\n  - Unusual enumeration of services and resources through cloud APIs such as AWS CLI `describe-*`, Azure Resource Manager queries, or GCP project listings.

(telemetry: AWS:CloudTrail:DescribeInstances, DescribeServices, ListFunctions: High frequency enumeration calls or unusual user agents performing discovery, AWS:CloudTrail:AssumeRole: Discovery actions tied to assumed identities outside of normal context)\n  - Enumeration of directories, applications, or service principals through APIs such as Microsoft Graph or Okta API. […]\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 T1529 System Shutdown/Reboot\n**ATT&CK T1529 System Shutdown/Reboot (full record).** Adversaries may shutdown/reboot systems to interrupt access to, or aid in the destruction of, those systems. Operating systems may contain commands to initiate a shutdown/reboot of a machine or network device. In some cases, these commands may also be used to initiate a shutdown/reboot of a remote computer or network device via Network Device CLI (e.g. `reload`). They may also include shutdown/reboot of a virtual machine via hypervisor / cloud consoles or command line tools.\n\nShutting down or rebooting systems may disrupt access to computer resources for legitimate users while also impeding incident response/recovery.\n\nAdversaries may also use Windows API functions, such as `InitializeSystemShutdownExW` or `ExitWindowsEx`, to force a system to shut down or reboot. Alternatively, the `NtRaiseHardError`or `ZwRaiseHardError` Windows API functions with the `ResponseOption` parameter set to `OptionShutdownSystem` may deliver a “blue screen of death” (BSOD) to a system. In order to leverage these API functions, an adversary may need to acquire `SeShutdownPrivilege` (e.g., via Access Token Manipulation).\nIn some cases, the system may not be able to boot again.\n\nAdversaries may attempt to shutdown/reboot a system after impacting it in other ways, such as Disk Structure Wipe or Inhibit System Recovery, to hasten the intended effects on system availability.\n\n**Classification.** - Tactics: impact\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n\n**Detection strategies and analytics.** - **Multi-Platform Shutdown or Reboot Detection via Execution and Host Status Events**\n  - Correlate process execution of shutdown/reboot commands (e.g., shutdown.exe, restart-computer) with host status change logs (Event IDs 1074, 6006) and absence of related administrative context (e.g., user not in Helpdesk group).

After a user logs on, the system generates and stores a variety of credential materials in LSASS process memory. These credential materials can be harvested by an administrative user or SYSTEM and used to conduct Lateral Movement using Use Alternate Authentication Material.\n\nAs well as in-memory techniques, the LSASS process memory can be dumped from the target host and analyzed on a local system.\n\nFor example, on the target host use procdump:\n\n* `procdump -ma lsass.exe lsass_dump`\n\nLocally, mimikatz can be run using:\n\n* `sekurlsa::Minidump lsassdump.dmp`\n* `sekurlsa::logonPasswords`\n\nBuilt-in Windows tools such as `comsvcs.dll` can also be used:\n\n* `rundll32.exe C:\\Windows\\System32\\comsvcs.dll MiniDump PID lsass.dmp full`\n\nSimilar to Image File Execution Options Injection, the silent process exit mechanism can be abused to create a memory dump of `lsass.exe` through Windows Error Reporting (`WerFault.exe`).\n\nWindows Security Support Provider (SSP) DLLs are loaded into LSASS process at system start.

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. 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\n**Classification.** - Tactics: command-and-control\n- Platforms: Linux, macOS, Windows, ESXi\n- Sub-technique of: T1102 Web Service - Adversaries may use an existing, legitimate external Web service as a means for relaying data to/from a compromised system.\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 Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n\n**Detection strategies and analytics.** - **Detect One-Way Web Service Command Channels**\n  - Suspicious process initiating outbound connections to web services without corresponding response or return traffic, indicative of one-way command channels. […]\n\n## Reference: ATT&CK T1104 Multi-Stage Channels\n**ATT&CK T1104 Multi-Stage Channels (full record).** Adversaries may create multiple stages for command and control that are employed under different conditions or for certain functions. 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. The loader may also have backup first-stage callbacks or Fallback Channels in case the original first-stage communication path is discovered and blocked.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Linux, macOS, Windows, ESXi\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n\n**Detection strategies and analytics.** - **Detect Multi-Stage Command and Control Channels**\n  - Initial process initiates outbound connection to first-stage C2, receives payloads or commands, then spawns or injects into a second process that establishes a new outbound connection to an unrelated destination (second-stage C2).

(telemetry: auditd:SYSCALL:execve, connect, iptables:LOG:OUTBOUND)\n  - Initial process using NSURLSession or similar APIs reaches out to known staging domains, followed by creation of a reverse shell or RAT connecting to a second unrelated server. […]\n\n## Reference: ATT&CK T1106 Native API\n**ATT&CK T1106 Native API (full record).** Adversaries may interact with the native OS application programming interface (API) to execute behaviors. 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. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. […]\n\n## Reference: ATT&CK T1110 Brute Force\n**ATT&CK T1110 Brute Force (full record).** 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. Brute forcing passwords can take place via interaction with a service that will check the validity of those credentials or offline against previously acquired credential data, such as password hashes.\n\nBrute forcing credentials may take place at various points during a breach. For example, adversaries may attempt to brute force access to Valid Accounts within a victim environment leveraging knowledge gathered from other post-compromise behaviors such as OS Credential Dumping, Account Discovery, or Password Policy Discovery. Adversaries may also combine brute forcing activity with behaviors such as External Remote Services as part of Initial Access.\n\nIf an adversary guesses the correct password but fails to login to a compromised account due to location-based conditional access policies, they may change their infrastructure until they match the victim’s location and therefore bypass those policies.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Containers, ESXi, IaaS, Identity Provider, Linux, macOS, Network Devices, Office Suite, SaaS, Windows\n\n**Sub-techniques.** - T1110.004 Credential Stuffing: Adversaries may use credentials obtained from breach dumps of unrelated accounts to gain access to target accounts through credential overlap.\n- T1110.002 Password Cracking: Adversaries may use password cracking to attempt to recover usable credentials, such as plaintext passwords, when credential material such as password hashes are obtained.\n- T1110.001 Password Guessing: Adversaries with no prior knowledge of legitimate credentials within the system or environment may guess passwords to attempt access to accounts.\n- T1110.003 Password Spraying: 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. […]"}]}

Adversaries will first gather information about victims through Phishing, social engineering, data breaches, or other avenues.\n2. Adversaries will then impersonate victims as they contact mobile carriers to request for the SIM swaps. For example, adversaries would provide victims’ name and address to mobile carriers; once authenticated, adversaries would request for victims’ phone numbers to be transferred to adversary-controlled SIM cards.\n3. Once completed, victims will lose mobile data, such as text messages and phone calls, on their mobile devices. In turn, adversaries will receive mobile data that was intended for the victims.\n\nAdversaries may use the intercepted SMS messages to log into online accounts that use SMS-based authentication. Specifically, adversaries may use SMS-based authentication to log into banking and/or cryptocurrency accounts, then transfer funds to adversary-controlled wallets.\n\n## Reference: ATT&CK T0835 Manipulate I/O Image\n**ATT&CK T0835 Manipulate I/O Image (full record).** Adversaries may manipulate the I/O image of PLCs through various means to prevent them from functioning as expected. 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. 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- **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 T0837 Loss of Protection\n**ATT&CK T0837 Loss of Protection (full record).** Adversaries may compromise protective system functions designed to prevent the effects of faults and abnormal conditions. This can result in equipment damage, prolonged process disruptions and hazards to personnel.\n\nMany faults and abnormal 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 protective system functions as a prerequisite to subsequent attack execution or to allow for future faults and abnormal conditions to go unchecked. Detection of a Loss of Protection by operators can result in the shutdown of a process due to strict policies regarding protection 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**Detection strategies and analytics.** - **Detection of Loss of Protection**\n  - No standard detection method currently exists for this technique. (telemetry: )\n\n**Tracked users (groups, malware, tools).** - Industroyer (malware): Industroyer is a sophisticated malware framework designed to cause an impact to the working processes of Industrial Control Systems (ICS), specifically components used in electrica.\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.

These trust objects may include accounts, credentials, and other authentication material applied to servers, tokens, and domains.\n\nManipulating these trusts may allow an adversary to escalate privileges and/or evade defenses by modifying settings to add objects which they control. For example, in Microsoft Active Directory (AD) environments, this may be used to forge SAML Tokens without the need to compromise the signing certificate to forge new credentials. Instead, an adversary can manipulate domain trusts to add their own signing certificate. An adversary may also convert an AD domain to a federated domain using Active Directory Federation Services (AD FS), which may enable malicious trust modifications such as altering the claim issuance rules to log in any valid set of credentials as a specified user.\n\nAn adversary may also add a new federated identity provider to an identity tenant such as Okta or AWS IAM Identity Center, which may enable the adversary to authenticate as any user of the tenant. This may enable the threat actor to gain broad access into a variety of cloud-based services that leverage the identity tenant. For example, in AWS environments, an adversary that creates a new identity provider for an AWS Organization will be able to federate into all of the AWS Organization member accounts without creating identities for each of the member accounts.\n\n## Reference: ATT&CK DET0692 Detection of Process Discovery\n**Detects.** - T1424 Process Discovery\n\n**Analytics.** - Analytic 1804: For Android, detect Process Discovery by correlating analyst-visible device/network evidence and management state;

An adversary may Create Snapshot of one or more volumes in an account, create a new instance, mount the snapshots, and then apply a less restrictive security policy to collect Data from Local System or for Remote Data Staging.\n\nCreating a new instance may also allow an adversary to carry out malicious activity within an environment without affecting the execution of current running instances.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: IaaS\n- Sub-technique of: T1578 Modify Cloud Compute Infrastructure - An adversary may attempt to modify a cloud account's compute service infrastructure to evade defenses. A modification to the compute service infrastructure can include the creation, deletion, or modification of one or more components such as compute instances, virtual machines, and snapshots.\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- **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 Modify Cloud Compute Infrastructure: Create Cloud Instance**\n  - Detection focuses on abnormal or unauthorized cloud instance creation events. From a defender’s perspective, suspicious behavior includes VM/instance creation by rarely used or newly created accounts, creation events from unusual geolocations, or rapid sequences of snapshot creation followed by instance creation and mounting.

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. In some of the worst cases for DDoS, so many systems are used to generate requests that each one only needs to send out a small amount of traffic to produce enough volume to exhaust the target's resources. In such circumstances, distinguishing DDoS traffic from legitimate clients becomes exceedingly difficult. Botnets have been used in some of the most high-profile DDoS attacks, such as the 2012 series of incidents that targeted major US banks.\n\nIn cases where traffic manipulation is used, there may be points in the global network (such as high traffic gateway routers) where packets can be altered and cause legitimate clients to execute code that directs network packets toward a target in high volume. This type of capability was previously used for the purposes of web censorship where client HTTP traffic was modified to include a reference to JavaScript that generated the DDoS code to overwhelm target web servers.\n\nFor attacks attempting to saturate the providing network, see Network Denial of Service.\n\n## Reference: ATT&CK AN1574 Analytic 1574\n**ATT&CK AN1574 Analytic 1574 (full record).** Unusual ESXi processes (vmx, hostd) reading datastore files and generating outbound HTTPS traffic toward external cloud storage endpoints.

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.

The only requirement to start a foreground service is showing a persistent notification to the user.\n\nMalicious applications may abuse the `startForeground` API method to continue running in the foreground, while presenting a notification to the user pretending to be a genuine application.

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\n- **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- **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- **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\n## Detection strategies and analytics\n- **Detection Strategy for T1542.001 Pre-OS Boot: System Firmware**\n  - Unexpected write operations to BIOS/UEFI firmware regions or EFI boot partitions that do not correlate with legitimate vendor firmware updates. API calls or utilities such as fwupdate.exe or vendor flash tools executed from non-administrative or non-IT management accounts. Suspicious raw disk writes targeting System Firmware GUID partitions followed by abnormal reboot sequences.

Files may be copied from an external adversary-controlled system through the command and control channel or through alternate protocols with another tool such as FTP.\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.

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\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- **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. 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\n## Detection strategies and analytics\n- **Detect WMI Event Subscription for Persistence via WmiPrvSE Process and MOF Compilation**\n  - Monitor for creation of WMI EventFilter, EventConsumer, and FilterToConsumerBinding objects through WMI or MOF file execution.

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. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Event Triggered Execution: AppInit DLLs (Windows)**\n  - Registry key modification to AppInit_DLLs value followed by anomalous DLL loading by processes importing user32.dll, especially unsigned or uncommon DLLs, suggesting unauthorized AppInit persistence or privilege escalation.

Its primary function is to gather information about the victim.\n- Cherry Picker (malware): Cherry Picker is a point of sale (PoS) memory scraper.\n- Ramsay (malware): Ramsay is an information stealing malware framework designed to collect and exfiltrate sensitive documents, including from air-gapped systems.\n\n## Reference: ATT&CK T1040 Network Sniffing\n**ATT&CK T1040 Network Sniffing (full record).** Adversaries may passively sniff network traffic to capture information about an environment, including authentication material passed over the network. Network sniffing refers to using the network interface on a system to monitor or capture information sent over a wired or wireless connection. An adversary may place a network interface into promiscuous mode to passively access data in transit over the network, or use span ports to capture a larger amount of data.\n\nData captured via this technique may include user credentials, especially those sent over an insecure, unencrypted protocol. Techniques for name service resolution poisoning, such as Name Resolution Poisoning and SMB Relay, can also be used to capture credentials to websites, proxies, and internal systems by redirecting traffic to an adversary.\n\nNetwork sniffing may reveal configuration details, such as running services, version numbers, and other network characteristics (e.g. IP addresses, hostnames, VLAN IDs) necessary for subsequent Lateral Movement and/or Stealth activities. Adversaries may likely also utilize network sniffing during Adversary-in-the-Middle (AiTM) to passively gain additional knowledge about the environment.\n\nIn cloud-based environments, adversaries may still be able to use traffic mirroring services to sniff network traffic from virtual machines. 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. Often, much of this traffic will be in cleartext due to the use of TLS termination at the load balancer level to reduce the strain of encrypting and decrypting traffic. The adversary can then use exfiltration techniques such as Transfer Data to Cloud Account in order to access the sniffed traffic.\n\nOn network devices, adversaries may perform network captures using Network Device CLI commands such as `monitor capture`.\n\n**Classification.** - Tactics: credential-access, discovery\n- Platforms: IaaS, Linux, macOS, Network Devices, 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.

[…]\n\n## Reference: ATT&CK T1046 Network Service Discovery\n**ATT&CK T1046 Network Service Discovery (full record).** Adversaries may attempt to get a listing of services running on remote hosts and local network infrastructure devices, including those that may be vulnerable to remote software exploitation. Common methods to acquire this information include port, vulnerability, and/or wordlist scans using tools that are brought onto a system.\n\nWithin cloud environments, adversaries may attempt to discover services running on other cloud hosts. Additionally, if the cloud environment is connected to a on-premises environment, adversaries may be able to identify services running on non-cloud systems as well.\n\nWithin macOS environments, adversaries may use the native Bonjour application to discover services running on other macOS hosts within a network. The Bonjour mDNSResponder daemon automatically registers and advertises a host’s registered services on the network. For example, adversaries can use a mDNS query (such as `dns-sd -B _ssh._tcp.`) to find other systems broadcasting the ssh service.\n\n**Classification.** - Tactics: discovery\n- Platforms: Containers, IaaS, Linux, macOS, Network Devices, 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- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\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\n**Detection strategies and analytics.** - **Behavioral Detection Strategy for Network Service Discovery Across Platforms**\n  - Detects processes performing network enumeration (e.g., port scans, service probing) by correlating process creation, socket connections, and sequential destination IP probing within a time window. […]\n\n## Reference: ATT&CK T1047 Windows Management Instrumentation\n**ATT&CK T1047 Windows Management Instrumentation (full record).** Adversaries may abuse Windows Management Instrumentation (WMI) to execute malicious commands and payloads. WMI is designed for programmers and is the infrastructure for management data and operations on Windows systems. WMI is an administration feature that provides a uniform environment to access Windows system components.\n\nThe WMI service enables both local and remote access, though the latter is facilitated by Remote Services such as Distributed Component Object Model and Windows Remote Management. Remote WMI over DCOM operates using port 135, whereas WMI over WinRM operates over port 5985 when using HTTP and 5986 for HTTPS.\n\nAn adversary can use WMI to interact with local and remote systems and use it as a means to execute various behaviors, such as gathering information for Discovery as well as Execution of commands and payloads. For example, `wmic.exe` can be abused by an adversary to delete shadow copies with the command `wmic.exe Shadowcopy Delete` (i.e., Inhibit System Recovery).\n\n**Note:** `wmic.exe` is deprecated as of January of 2024, with the WMIC feature being “disabled by default” on Windows 11+. WMIC will be removed from subsequent Windows releases and replaced by PowerShell as the primary WMI interface. In addition to PowerShell and tools like `wbemtool.exe`, COM APIs can also be used to programmatically interact with WMI via C++,.NET, VBScript, etc.\n\n**Classification.** - Tactics: execution\n- Platforms: Windows\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- **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.

The Microsoft Windows Application Compatibility Infrastructure/Framework (Application Shim) was created to allow for backward compatibility of software as the operating system codebase changes over time. For example, the application shimming feature allows developers to apply fixes to applications (without rewriting code) that were created for Windows XP so that it will work with Windows 10.\n\nWithin the framework, shims are created to act as a buffer between the program (or more specifically, the Import Address Table) and the Windows OS. When a program is executed, the shim cache is referenced to determine if the program requires the use of the shim database (.sdb). If so, the shim database uses hooking to redirect the code as necessary in order to communicate with the OS.\n\nA list of all shims currently installed by the default Windows installer (sdbinst.exe) is kept in:\n\n* `%WINDIR%\\AppPatch\\sysmain.sdb` and\n* `hklm\\software\\microsoft\\windows nt\\currentversion\\appcompatflags\\installedsdb`\n\nCustom databases are stored in:\n\n* `%WINDIR%\\AppPatch\\custom & %WINDIR%\\AppPatch\\AppPatch64\\Custom` and\n* `hklm\\software\\microsoft\\windows nt\\currentversion\\appcompatflags\\custom`\n\nTo keep shims secure, Windows designed them to run in user mode so they cannot modify the kernel and you must have administrator privileges to install a shim. However, certain shims can be used to Bypass User Account Control (UAC and RedirectEXE), inject DLLs into processes (InjectDLL), disable Data Execution Prevention (DisableNX) and Structure Exception Handling (DisableSEH), and intercept memory addresses (GetProcAddress).\n\nUtilizing these shims may allow an adversary to perform several malicious acts such as elevate privileges, install backdoors, disable defenses like Windows Defender, etc. Shims can also be abused to establish persistence by continuously being invoked by affected programs.\n\n## Reference: ATT&CK AN1558 Analytic 1558\n**ATT&CK AN1558 Analytic 1558 (full record).** Detection of unset HISTFILE or modified history variables in ESXi shell sessions.

Guardrails ensure that a payload only executes against an intended target and reduces collateral damage from an adversary’s campaign. Values an adversary can provide about a target system or environment to use as guardrails may include specific network share names, attached physical devices, files, joined Active Directory (AD) domains, and local/external IP addresses.\n\nGuardrails can be used to prevent exposure of capabilities in environments that are not intended to be compromised or operated within. This use of guardrails is distinct from typical Virtualization/Sandbox Evasion. While use of Virtualization/Sandbox Evasion may involve checking for known sandbox values and continuing with execution only if there is no match, the use of guardrails will involve checking for an expected target-specific value and only continuing with execution if there is such a match.\n\nAdversaries may identify and block certain user-agents to evade defenses and narrow the scope of their attack to victims and platforms on which it will be most effective. A user-agent self-identifies data such as a user's software application, operating system, vendor, and version. Adversaries may check user-agents for operating system identification and then only serve malware for the exploitable software while ignoring all other operating systems.\n\n**Classification.** - Tactics: stealth\n- Platforms: ESXi, Linux, macOS, Windows\n\n**Sub-techniques.** - T1480.001 Environmental Keying: Adversaries may environmentally key payloads or other features of malware to evade defenses and constraint execution to a specific target environment.\n- T1480.002 Mutual Exclusion: Adversaries may constrain execution or actions based on the presence of a mutex associated with malware.

[…]\n\n## Reference: ATT&CK T1480.001 Environmental Keying\n**ATT&CK T1480.001 Environmental Keying (full record).** Adversaries may environmentally key payloads or other features of malware to evade defenses and constraint execution to a specific target environment. Environmental keying uses cryptography to constrain execution or actions based on adversary supplied environment specific conditions that are expected to be present on the target. Environmental keying is an implementation of Execution Guardrails that utilizes cryptographic techniques for deriving encryption/decryption keys from specific types of values in a given computing environment.\n\nValues can be derived from target-specific elements and used to generate a decryption key for an encrypted payload. Target-specific values can be derived from specific network shares, physical devices, software/software versions, files, joined AD domains, system time, and local/external IP addresses. By generating the decryption keys from target-specific environmental values, environmental keying can make sandbox detection, anti-virus detection, crowdsourcing of information, and reverse engineering difficult. These difficulties can slow down the incident response process and help adversaries hide their tactics, techniques, and procedures (TTPs).\n\nSimilar to Obfuscated Files or Information, adversaries may use environmental keying to help protect their TTPs and evade detection. Environmental keying may be used to deliver an encrypted payload to the target that will use target-specific values to decrypt the payload before execution. By utilizing target-specific values to decrypt the payload the adversary can avoid packaging the decryption key with the payload or sending it over a potentially monitored network connection. Depending on the technique for gathering target-specific values, reverse engineering of the encrypted payload can be exceptionally difficult. This can be used to prevent exposure of capabilities in environments that are not intended to be compromised or operated within.\n\nLike other Execution Guardrails, environmental keying can be used to prevent exposure of capabilities in environments that are not intended to be compromised or operated within. This activity is distinct from typical Virtualization/Sandbox Evasion. While use of Virtualization/Sandbox Evasion may involve checking for known sandbox values and continuing with execution only if there is no match, the use of environmental keying will involve checking for an expected target-specific value that must match for decryption and subsequent execution to be successful. […]\n\n## Reference: ATT&CK T1480.002 Mutual Exclusion\n**ATT&CK T1480.002 Mutual Exclusion (full record).** Adversaries may constrain execution or actions based on the presence of a mutex associated with malware. A mutex is a locking mechanism used to synchronize access to a resource. Only one thread or process can acquire a mutex at a given time.\n\nWhile local mutexes only exist within a given process, allowing multiple threads to synchronize access to a resource, system mutexes can be used to synchronize the activities of multiple processes. By creating a unique system mutex associated with a particular malware, adversaries can verify whether or not a system has already been compromised.\n\nIn Linux environments, malware may instead attempt to acquire a lock on a mutex file. If the malware is able to acquire the lock, it continues to execute; if it fails, it exits to avoid creating a second instance of itself.\n\nMutex names may be hard-coded or dynamically generated using a predictable algorithm.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1480 Execution Guardrails - Adversaries may use execution guardrails to constrain execution or actions based on adversary supplied and environment specific conditions that are expected to be present on the target.\n\n**Mitigations.** - **Do Not Mitigate**: The Do Not Mitigate category highlights scenarios where attempting to mitigate a specific technique may inadvertently increase the organization's security risk or operational instability. 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.\n\n**Detection strategies and analytics.** - **Detection of Mutex-Based Execution Guardrails Across Platforms**\n  - Adversary-created named mutex using system APIs (e.g., CreateMutexW) followed by conditional process termination or alternate code path indicating malware avoiding reinfection. (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=11)\n  - File lock acquired via open + flock or lockf on predictable path (e.g., /tmp/.lock123) followed by conditional early exit or divergent process behavior.

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## Reference: ATT&CK T1216.001 PubPrn\n**ATT&CK T1216.001 PubPrn (full record).** Adversaries may use PubPrn to proxy execution of malicious remote files. PubPrn.vbs is a Visual Basic script that publishes a printer to Active Directory Domain Services. The script may be signed by Microsoft and is commonly executed through the Windows Command Shell via `Cscript.exe`. For example, the following code publishes a printer within the specified domain: `cscript pubprn Printer1 LDAP://CN=Container1,DC=Domain1,DC=Com`.\n\nAdversaries may abuse PubPrn to execute malicious payloads hosted on remote sites. To do so, adversaries may set the second `script:` parameter to reference a scriptlet file (.sct) hosted on a remote site. An example command is `pubprn.vbs 127.0.0.1 script: This behavior may bypass signature validation restrictions and application control solutions that do not account for abuse of this script.\n\nIn later versions of Windows (10+), `PubPrn.vbs` has been updated to prevent proxying execution from a remote site. This is done by limiting the protocol specified in the second parameter to `LDAP://`, vice the `script:` moniker which could be used to reference remote code via HTTP(S).\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1216 System Script Proxy Execution - Adversaries may use trusted scripts, often signed with certificates, to proxy the execution of malicious files.

SyncAppvPublishingServer.vbs is a Visual Basic script associated with how Windows virtualizes applications (Microsoft Application Virtualization, or App-V). For example, Windows may render Win32 applications to users as virtual applications, allowing users to launch and interact with them as if they were installed locally.\n\nThe SyncAppvPublishingServer.vbs script is legitimate, may be signed by Microsoft, and is commonly executed from `\\System32` through the command line via `wscript.exe`.\n\nAdversaries may abuse SyncAppvPublishingServer.vbs to bypass PowerShell execution restrictions and evade defensive counter measures by \"living off the land.\" Proxying execution may function as a trusted/signed alternative to directly invoking `powershell.exe`.\n\nFor example, PowerShell commands may be invoked using:\n\n`SyncAppvPublishingServer.vbs \"n; {PowerShell}\"`\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1216 System Script Proxy Execution - Adversaries may use trusted scripts, often signed with certificates, to proxy the execution of malicious files.

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.\n\nSimilarly, on Linux systems adversaries may abuse trusted binaries such as `split` to proxy execution of malicious commands.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1218.005 Mshta: Adversaries may abuse mshta.exe to proxy execution of malicious.hta files and Javascript or VBScript through a trusted Windows utility.\n- T1218.014 MMC: Adversaries may abuse mmc.exe to proxy execution of malicious.msc files.\n- T1218.008 Odbcconf: Adversaries may abuse odbcconf.exe to proxy execution of malicious payloads.\n- T1218.015 Electron Applications: Adversaries may abuse components of the Electron framework to execute malicious code.

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).

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.

Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private that should not be distributed. Due to how asymmetric algorithms work, 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, ElGamal, and ECDSA.\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.

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.

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.

These methods can differ from platform-as-a-service (PaaS), to infrastructure-as-a-service (IaaS), or software-as-a-service (SaaS). Many services exist throughout the various cloud providers and can include Continuous Integration and Continuous Delivery (CI/CD), Lambda Functions, Entra ID, etc. They may also include security services, such as AWS GuardDuty and Microsoft Defender for Cloud, and logging services, such as AWS CloudTrail and Google Cloud Audit Logs.\n\nAdversaries may attempt to discover information about the services enabled throughout the environment. Azure tools and APIs, such as the Microsoft Graph API and Azure Resource Manager API, can enumerate resources and services, including applications, management groups, resources and policy definitions, and their relationships that are accessible by an identity.\n\nFor example, Stormspotter is an open source tool for enumerating and constructing a graph for Azure resources and services, and Pacu is an open source AWS exploitation framework that supports several methods for discovering cloud services.\n\nAdversaries may use the information gained to shape follow-on behaviors, such as targeting data or credentials from enumerated services or evading identified defenses through Disable or Modify Tools or Disable or Modify Cloud Log.\n\n**Classification.** - Tactics: discovery\n- Platforms: IaaS, Identity Provider, Office Suite, SaaS\n\n**Detection strategies and analytics.** - **Detection Strategy for Cloud Service Discovery**\n  - Unusual enumeration of services and resources through cloud APIs such as AWS CLI `describe-*`, Azure Resource Manager queries, or GCP project listings.

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.

[…]\n\n## Reference: ATT&CK T1555.001 Keychain\n**ATT&CK T1555.001 Keychain (full record).** Adversaries may acquire credentials from Keychain. Keychain (or Keychain Services) is the macOS credential management system that stores account names, passwords, private keys, certificates, sensitive application data, payment data, and secure notes. There are three types of Keychains: Login Keychain, System Keychain, and Local Items (iCloud) Keychain. The default Keychain is the Login Keychain, which stores user passwords and information. The System Keychain stores items accessed by the operating system, such as items shared among users on a host. The Local Items (iCloud) Keychain is used for items synced with Apple’s iCloud service.\n\nKeychains can be viewed and edited through the Keychain Access application or using the command-line utility `security`. Keychain files are located in `~/Library/Keychains/`, `/Library/Keychains/`, and `/Network/Library/Keychains/`.\n\nAdversaries may gather user credentials from Keychain storage/memory. For example, the command `security dump-keychain –d` will dump all Login Keychain credentials from `~/Library/Keychains/login.keychain-db`. Adversaries may also directly read Login Keychain credentials from the `~/Library/Keychains/login.keychain` file. Both methods require a password, where the default password for the Login Keychain is the current user’s password to login to the macOS host.\n\n**Classification.** - Tactics: credential-access\n- Platforms: macOS\n- Sub-technique of: T1555 Credentials from Password Stores - Adversaries may search for common password storage locations to obtain user credentials. Passwords are stored in several places on a system, depending on the operating system or application holding the credentials.\n\n**Mitigations.** - **Password Policies**: Set 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. […]\n\n## Reference: ATT&CK T1555.002 Securityd Memory\n**ATT&CK T1555.002 Securityd Memory (full record).** An adversary with root access may gather credentials by reading `securityd`’s memory. `securityd` is a service/daemon responsible for implementing security protocols such as encryption and authorization. A privileged adversary may be able to scan through `securityd`'s memory to find the correct sequence of keys to decrypt the user’s logon keychain. This may provide the adversary with various plaintext passwords, such as those for users, WiFi, mail, browsers, certificates, secure notes, etc.\n\nIn OS X prior to El Capitan, users with root access can read plaintext keychain passwords of logged-in users because Apple’s keychain implementation allows these credentials to be cached so that users are not repeatedly prompted for passwords. Apple’s `securityd` utility takes the user’s logon password, encrypts it with PBKDF2, and stores this master key in memory. Apple also uses a set of keys and algorithms to encrypt the user’s password, but once the master key is found, an adversary need only iterate over the other values to unlock the final password.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Linux, macOS\n- Sub-technique of: T1555 Credentials from Password Stores - Adversaries may search for common password storage locations to obtain user credentials.

Where secrets managers are in use, cloud services can dynamically acquire credentials via API requests rather than accessing secrets insecurely stored in plain text files or environment variables.\n\nIf an adversary is able to gain sufficient privileges in a cloud environment – for example, by obtaining the credentials of high-privileged Cloud Accounts or compromising a service that has permission to retrieve secrets – they may be able to request secrets from the secrets manager. This can be accomplished via commands such as `get-secret-value` in AWS, `gcloud secrets describe` in GCP, and `az key vault secret show` in Azure.\n\n**Note:** this technique is distinct from Cloud Instance Metadata API in that the credentials are being directly requested from the cloud secrets manager, rather than through the medium of the instance metadata API.\n\n## Reference: ATT&CK T0885 Commonly Used Port\n**ATT&CK T0885 Commonly Used Port (full record).** Adversaries may communicate over a commonly used port to bypass firewalls or network detection systems and to blend in with normal network activity, to avoid more detailed inspection. They may use the protocol associated with the port, or a completely different protocol. They may use commonly open ports, such as the examples provided below.\n\n* TCP:80 (HTTP)\n* TCP:443 (HTTPS)\n* TCP/UDP:53 (DNS)\n* TCP:1024-4999 (OPC on XP/Win2k3)\n* TCP:49152-65535 (OPC on Vista and later)\n* TCP:23 (TELNET)\n* UDP:161 (SNMP)\n* TCP:502 (MODBUS)\n* TCP:102 (S7comm/ISO-TSAP)\n* TCP:20000 (DNP3)\n* TCP:44818 (Ethernet/IP)\n\n**Classification.** - Tactics: command-and-control\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 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. 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## Reference: ATT&CK T0886 Remote Services\n**ATT&CK T0886 Remote Services (full record).** Adversaries may leverage remote services to move between assets and network segments. 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. An adversary may leverage this same information by issuing calls directly to the system's API.\n\n**Classification.** - Tactics: discovery\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\n**Detection strategies and analytics.** - **Detection of Remote System Information Discovery**\n  - Real-time monitoring identifies remote Windows system-information queries using WMI/CIM, WinRM, PowerShell remoting, or equivalent management tooling where the command names a non-local target and the account/source is outside the approved management baseline. OT operational-fidelity gate: Do not alert on novelty, scan/read volume, or enumeration alone. Alert when the source role is not authorized for discovery/polling and the target scope, address/tag range, protocol, or rate deviates from the established operational baseline. […]\n\n## Reference: ATT&CK T0889 Modify Program\n**ATT&CK T0889 Modify Program (full record).** Adversaries may modify or add a program on a controller to affect how it interacts with the physical process, peripheral devices and other hosts on the network. Modification to controller programs can be accomplished using a Program Download in addition to other types of program modification such as online edit and program append.\n\nProgram modification encompasses the addition and modification of instructions and logic contained in Program Organization Units (POU) and similar programming elements found on controllers. This can include, for example, adding new functions to a controller, modifying the logic in existing functions and making new calls from one function to another.\n\nSome programs may allow an adversary to interact directly with the native API of the controller to take advantage of obscure features or vulnerabilities.\n\n**Classification.** - Tactics: persistence\n- Platforms: Embedded\n\n**Mitigations.** - **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- **Code Signing**: Enforce binary and application integrity with digital signature verification to prevent untrusted code from executing.\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- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device.

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- **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.

Environmental keying uses cryptography to constrain execution or actions based on adversary supplied environment specific conditions that are expected to be present on the target. Environmental keying is an implementation of Execution Guardrails that utilizes cryptographic techniques for deriving encryption/decryption keys from specific types of values in a given computing environment.\n\nValues can be derived from target-specific elements and used to generate a decryption key for an encrypted payload. Target-specific values can be derived from specific network shares, physical devices, software/software versions, files, joined AD domains, system time, and local/external IP addresses. By generating the decryption keys from target-specific environmental values, environmental keying can make sandbox detection, anti-virus detection, crowdsourcing of information, and reverse engineering difficult. These difficulties can slow down the incident response process and help adversaries hide their tactics, techniques, and procedures (TTPs).\n\nSimilar to Obfuscated Files or Information, adversaries may use environmental keying to help protect their TTPs and evade detection. Environmental keying may be used to deliver an encrypted payload to the target that will use target-specific values to decrypt the payload before execution. By utilizing target-specific values to decrypt the payload the adversary can avoid packaging the decryption key with the payload or sending it over a potentially monitored network connection. Depending on the technique for gathering target-specific values, reverse engineering of the encrypted payload can be exceptionally difficult. This can be used to prevent exposure of capabilities in environments that are not intended to be compromised or operated within.\n\nLike other Execution Guardrails, environmental keying can be used to prevent exposure of capabilities in environments that are not intended to be compromised or operated within. This activity is distinct from typical Virtualization/Sandbox Evasion. While use of Virtualization/Sandbox Evasion may involve checking for known sandbox values and continuing with execution only if there is no match, the use of environmental keying will involve checking for an expected target-specific value that must match for decryption and subsequent execution to be successful. […]\n\n## Reference: ATT&CK T1480.002 Mutual Exclusion\n**ATT&CK T1480.002 Mutual Exclusion (full record).** Adversaries may constrain execution or actions based on the presence of a mutex associated with malware. A mutex is a locking mechanism used to synchronize access to a resource. Only one thread or process can acquire a mutex at a given time.\n\nWhile local mutexes only exist within a given process, allowing multiple threads to synchronize access to a resource, system mutexes can be used to synchronize the activities of multiple processes. By creating a unique system mutex associated with a particular malware, adversaries can verify whether or not a system has already been compromised.\n\nIn Linux environments, malware may instead attempt to acquire a lock on a mutex file. If the malware is able to acquire the lock, it continues to execute; if it fails, it exits to avoid creating a second instance of itself.\n\nMutex names may be hard-coded or dynamically generated using a predictable algorithm.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1480 Execution Guardrails - Adversaries may use execution guardrails to constrain execution or actions based on adversary supplied and environment specific conditions that are expected to be present on the target.\n\n**Mitigations.** - **Do Not Mitigate**: The Do Not Mitigate category highlights scenarios where attempting to mitigate a specific technique may inadvertently increase the organization's security risk or operational instability. 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.\n\n**Detection strategies and analytics.** - **Detection of Mutex-Based Execution Guardrails Across Platforms**\n  - Adversary-created named mutex using system APIs (e.g., CreateMutexW) followed by conditional process termination or alternate code path indicating malware avoiding reinfection. (telemetry: WinEventLog:Sysmon:EventCode=1, WinEventLog:Sysmon:EventCode=11)\n  - File lock acquired via open + flock or lockf on predictable path (e.g., /tmp/.lock123) followed by conditional early exit or divergent process behavior.

Popular websites and social media, acting as a mechanism for C2, may give a significant amount of cover. This is 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 Web services may also protect back-end C2 infrastructure from discovery through malware binary analysis, or enable operational resiliency (since this infrastructure may be dynamically changed).\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Android, iOS\n\n**Sub-techniques.** - T1481.001 Dead Drop Resolver: Adversaries may use an existing, legitimate external Web service to host information that points to additional command and control (C2) infrastructure.\n- T1481.003 One-Way Communication: Adversaries may use an existing, legitimate external Web service channel as a means for sending commands to a compromised system without receiving return output.\n- T1481.002 Bidirectional Communication: Adversaries may use an existing, legitimate external Web service channel as a means for sending commands to and receiving output from a compromised system.\n\n**Detection strategies and analytics.** - **Detection of Web Service**\n  - For Android, detect Web Service by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private that should not be distributed. Due to how asymmetric algorithms work, 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, ElGamal, and ECDSA.\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: 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**Detection strategies and analytics.** - **Detection of Asymmetric Cryptography**\n  - For Android, detect Asymmetric Cryptography from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events. […]\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.

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.

Many services exist throughout the various cloud providers and can include Continuous Integration and Continuous Delivery (CI/CD), Lambda Functions, Entra ID, etc. They may also include security services, such as AWS GuardDuty and Microsoft Defender for Cloud, and logging services, such as AWS CloudTrail and Google Cloud Audit Logs.\n\nAdversaries may attempt to discover information about the services enabled throughout the environment. Azure tools and APIs, such as the Microsoft Graph API and Azure Resource Manager API, can enumerate resources and services, including applications, management groups, resources and policy definitions, and their relationships that are accessible by an identity.\n\nFor example, Stormspotter is an open source tool for enumerating and constructing a graph for Azure resources and services, and Pacu is an open source AWS exploitation framework that supports several methods for discovering cloud services.\n\nAdversaries may use the information gained to shape follow-on behaviors, such as targeting data or credentials from enumerated services or evading identified defenses through Disable or Modify Tools or Disable or Modify Cloud Log.\n\n**Classification.** - Tactics: discovery\n- Platforms: IaaS, Identity Provider, Office Suite, SaaS\n\n**Detection strategies and analytics.** - **Detection Strategy for Cloud Service Discovery**\n  - Unusual enumeration of services and resources through cloud APIs such as AWS CLI `describe-*`, Azure Resource Manager queries, or GCP project listings.

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).

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.

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## Reference: ATT&CK AN1444 Analytic 1444\n**ATT&CK AN1444 Analytic 1444 (full record).** Detects suspicious access to SSSD secrets database and Kerberos key material indicating ticket theft or replay attempts.

Extended attributes are key-value pairs of file and directory metadata used by both macOS and Linux. They are not visible through standard tools like `Finder`, `ls`, or `cat` and require utilities such as `xattr` (macOS) or `getfattr` (Linux) for inspection. Operating systems and applications use xattrs for tagging, integrity checks, and access control. On Linux, xattrs are organized into namespaces such as `user.` (user permissions), `trusted.` (root permissions), `security.`, and `system.`, each with specific permissions. On macOS, xattrs are flat strings without namespace prefixes, commonly prefixed with `com.apple.*` (e.g., `com.apple.quarantine`, `com.apple.metadata:_kMDItemUserTags`) and used by system features like Gatekeeper and Spotlight.\n\nAn adversary may leverage xattrs by embedding a second-stage payload into the extended attribute of a legitimate file. On macOS, a payload can be embedded into a custom attribute using the `xattr` command. A separate loader can retrieve the attribute with `xattr -p`, decode the content, and execute it using a scripting interpreter. On Linux, an adversary may use `setfattr` to write a payload into the `user.` namespace of a legitimate file. A loader script can later extract the payload with `getfattr --only-values`, decode it, and execute it using bash or another interpreter. In both cases, because the primary file content remains unchanged, security tools and integrity checks that do not inspect extended attributes will observe the original file hash, allowing the malicious payload to evade detection.\n\n## Reference: ATT&CK AN1334 Analytic 1334\n**ATT&CK AN1334 Analytic 1334 (full record).** Monitor ESXi syslog and esxcli outputs for abnormal DNS resolver behavior, such as frequent domain-to-IP changes or unauthorized modifications of DNS settings used by management agents.

It was used by APT29 since at least February 2020.\n\n## ATT&CK T1568 Dynamic Resolution (full record)\nAdversaries may dynamically establish connections to command and control infrastructure to evade common detections and remediations. 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## Reference: ATT&CK T1059.013 Container CLI/API\n**ATT&CK T1059.013 Container CLI/API (full record).** Adversaries may abuse built-in CLI tools or API calls to execute malicious commands in containerized environments.\n\nThe Docker CLI is used for managing containers via an exposed API point from the `dockerd` daemon. 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.

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. […]\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. 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- **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.

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.

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\nFor example, the registry path `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\WinSock2\\Parameters` contains the `AutodiaDLL` value, which specifies the DLL to be loaded for autodial funcitionality. An adversary could set the `AutodiaDLL` to point to a hijacked or malicious DLL:\n\n`\"AutodialDLL\"=\"c:\\temp\\foo.dll\"`\n\nThis ensures persistence, as it causes the DLL (in this case, foo.dll) to be loaded each time the Winsock 2 library is invoked.\n\n## Reference: ATT&CK DET0098 Detect abuse of Windows BITS Jobs for download, execution and persistence\n**Detects.** - T1197 BITS Jobs\n\n**Analytics.** - Analytic 0274: Behavioral chain: (1) An actor creates or modifies a BITS job via bitsadmin.exe, PowerShell BITS cmdlets, or COM; (2) the job performs HTTP(S)/SMB network transfers while the owning user is logged on; (3) upon job completion/error, BITS launches a notify command (SetNotifyCmdLine) from svchost.exe -.\n\n## Reference: ATT&CK DET0099 Detection Strategy for T1542.001 Pre-OS Boot: System Firmware\n**Detects.** - T1542.001 System Firmware\n\n**Analytics.** - Analytic 0275: Unexpected write operations to BIOS/UEFI firmware regions or EFI boot partitions that do not correlate with legitimate vendor firmware updates.

Operating systems may have mechanisms for automatically running a program on system boot or account logon. These mechanisms may include automatically executing programs that are placed in specially designated directories or are referenced by repositories that store configuration information, such as the Windows Registry. An adversary may achieve the same goal by modifying or extending features of the kernel.\n\nSince some boot or logon autostart programs run with higher privileges, an adversary may leverage these to elevate privileges.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Linux, macOS, Windows, Network Devices\n\n**Sub-techniques.** - T1547.009 Shortcut Modification: Adversaries may create or modify shortcuts that can execute a program during system boot or user login.\n- T1547.006 Kernel Modules and Extensions: Adversaries may modify the kernel to automatically execute programs on system boot.

Adding an entry to the \"run keys\" in the Registry or startup folder will cause the program referenced to be executed when a user logs in. These programs will be executed under the context of the user and will have the account's associated permissions level.\n\nThe following run keys are created by default on Windows systems:\n\n* `HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Run`\n* `HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\RunOnce`\n* `HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Run`\n* `HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\RunOnce`\n\nRun keys may exist under multiple hives. The `HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\RunOnceEx` is also available but is not created by default on Windows Vista and newer. Registry run key entries can reference programs directly or list them as a dependency. For example, it is possible to load a DLL at logon using a \"Depend\" key with RunOnceEx: `reg add HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunOnceEx\\0001\\Depend /v 1 /d \"C:\\temp\\evil[.]dll\"`\n\nPlacing a program within a startup folder will also cause that program to execute when a user logs in. There is a startup folder location for individual user accounts as well as a system-wide startup folder that will be checked regardless of which user account logs in. The startup folder path for the current user is `C:\\Users\\\\[Username]\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup`.

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. […]\n\n## Reference: ATT&CK T1547.004 Winlogon Helper DLL\n**ATT&CK T1547.004 Winlogon Helper DLL (full record).** Adversaries may abuse features of Winlogon to execute DLLs and/or executables when a user logs in. Winlogon.exe is a Windows component responsible for actions at logon/logoff as well as the secure attention sequence (SAS) triggered by Ctrl-Alt-Delete. Registry entries in `HKLM\\Software[\\\\Wow6432Node\\\\]\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\` and `HKCU\\Software\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\` are used to manage additional helper programs and functionalities that support Winlogon.\n\nMalicious modifications to these Registry keys may cause Winlogon to load and execute malicious DLLs and/or executables. Specifically, the following subkeys have been known to be possibly vulnerable to abuse:\n\n* Winlogon\\Notify - points to notification package DLLs that handle Winlogon events\n* Winlogon\\Userinit - points to userinit.exe, the user initialization program executed when a user logs on\n* Winlogon\\Shell - points to explorer.exe, the system shell executed when a user logs on\n\nAdversaries may take advantage of these features to repeatedly execute malicious code and establish persistence.\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.** - **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- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.

Rather than developing their own capabilities in-house, adversaries may purchase, freely download, or steal them.\n\n## Mitigations\n- **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\n- **Detection of Digital Certificates**\n  - Consider use of services that may aid in the tracking of newly issued certificates and/or certificates in use on sites across the Internet. In some cases it may be possible to pivot on known pieces of certificate information to uncover other adversary infrastructure. Some server-side components of adversary tools may have default values set for SSL/TLS certificates.\nMonitor for logged network traffic in response to a scan showing both protocol header and body values that may buy and/or steal SSL/TLS certificates that can be used during targeting.

With this technique, the user's web browser is targeted and exploited simply by visiting the compromised website.\n\nThe adversary may target a specific community, such as trusted third party suppliers or other industry specific groups, which often visit the target website. This kind of targeted attack relies on a common interest, and is known as a strategic web compromise or watering hole attack.\n\nThe National Cyber Awareness System (NCAS) has issued a Technical Alert (TA) regarding Russian government cyber activity targeting critical infrastructure sectors. Analysis by DHS and FBI has noted two distinct categories of victims in the Dragonfly campaign on the Western energy sector: staging and intended targets. The adversary targeted the less secure networks of staging targets, including trusted third-party suppliers and related peripheral organizations. Initial access to the intended targets used watering hole attacks to target process control, ICS, and critical infrastructure related trade publications and informational websites.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Windows, Linux\n\n**Mitigations.** - **Update Software**: Perform regular software updates to mitigate exploitation risk.

Internet-facing software may be user applications, underlying networking implementations, an assets operating system, weak defenses, etc. Targets of this technique may be intentionally exposed for the purpose of remote management and visibility.\n\nAn adversary may seek to target public-facing applications as they may provide direct access into an ICS environment or the ability to move into the ICS network. Publicly exposed applications may be found through online tools that scan the internet for open ports and services. Version numbers for the exposed application may provide adversaries an ability to target specific known vulnerabilities. Exposed control protocol or remote access ports found in Commonly Used Port may be of interest by adversaries.\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.

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## Reference: ATT&CK T0820 Exploitation for Evasion\n**ATT&CK T0820 Exploitation for Evasion (full record).** Adversaries may exploit a software vulnerability to take advantage of a programming error in a program, service, or within the operating system software or kernel itself to evade detection. Vulnerabilities may exist in software that can be used to disable or circumvent security features.\n\nAdversaries may have prior knowledge through Remote System Information Discovery about security features implemented on control devices.

[…]\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.

SSL/TLS certificates are designed to instill trust. They 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 with its owner.\n\nAdversaries may purchase or steal SSL/TLS certificates to further their operations, such as encrypting C2 traffic (ex: Asymmetric Cryptography with Web Protocols) or even enabling Adversary-in-the-Middle if the certificate is trusted or otherwise added to the root of trust (i.e. Install Root Certificate). The purchase of digital certificates may be done using a front organization or using information stolen from a previously compromised entity that allows the adversary to validate to a certificate provider as that entity. Adversaries may also steal certificate materials directly from a compromised third-party, including from certificate authorities. Adversaries may register or hijack domains that they will later purchase an SSL/TLS certificate for.\n\nCertificate authorities exist that allow adversaries to acquire SSL/TLS certificates, such as domain validation certificates, for free.\n\nAfter obtaining a digital certificate, an adversary may then install that certificate (see Install Digital Certificate) on infrastructure under their control.\n\n## Reference: ATT&CK T1547.004 Winlogon Helper DLL\n**ATT&CK T1547.004 Winlogon Helper DLL (full record).** Adversaries may abuse features of Winlogon to execute DLLs and/or executables when a user logs in. Winlogon.exe is a Windows component responsible for actions at logon/logoff as well as the secure attention sequence (SAS) triggered by Ctrl-Alt-Delete. Registry entries in `HKLM\\Software[\\\\Wow6432Node\\\\]\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\` and `HKCU\\Software\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\` are used to manage additional helper programs and functionalities that support Winlogon.\n\nMalicious modifications to these Registry keys may cause Winlogon to load and execute malicious DLLs and/or executables. Specifically, the following subkeys have been known to be possibly vulnerable to abuse:\n\n* Winlogon\\Notify - points to notification package DLLs that handle Winlogon events\n* Winlogon\\Userinit - points to userinit.exe, the user initialization program executed when a user logs on\n* Winlogon\\Shell - points to explorer.exe, the system shell executed when a user logs on\n\nAdversaries may take advantage of these features to repeatedly execute malicious code and establish persistence.\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 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- **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 T1547.005 Security Support Provider\n**ATT&CK T1547.005 Security Support Provider (full record).** Adversaries may abuse security support providers (SSPs) to execute DLLs when the system boots. Windows SSP DLLs are loaded into the Local Security Authority (LSA) process at system start. Once loaded into the LSA, SSP DLLs have access to encrypted and plaintext passwords that are stored in Windows, such as any logged-on user's Domain password or smart card PINs.\n\nThe SSP configuration is stored in two Registry keys: `HKLM\\SYSTEM\\CurrentControlSet\\Control\\Lsa\\Security Packages` and `HKLM\\SYSTEM\\CurrentControlSet\\Control\\Lsa\\OSConfig\\Security Packages`. An adversary may modify these Registry keys to add new SSPs, which will be loaded the next time the system boots, or when the AddSecurityPackage Windows API function is called.\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.** - **Registry and LSASS Monitoring for Security Support Provider Abuse**\n  - Monitor registry modifications to `HKLM\\SYSTEM\\CurrentControlSet\\Control\\Lsa\\Security Packages` or `...\\OSConfig\\Security Packages`, especially insertions of new DLL entries. Correlate this with subsequent DLL module loads into `lsass.exe`. Track unsigned or anomalous DLLs loading into LSASS using image load auditing. […]\n\n## Reference: ATT&CK T1547.006 Kernel Modules and Extensions\n**ATT&CK T1547.006 Kernel Modules and Extensions (full record).** Adversaries may modify the kernel to automatically execute programs on system boot. Loadable Kernel Modules (LKMs) are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need to reboot the system. For example, one type of module is the device driver, which allows the kernel to access hardware connected to the system.\n\nWhen used maliciously, LKMs can be a type of kernel-mode Rootkit that run with the highest operating system privilege (Ring 0). Common features of LKM based rootkits include: hiding itself, selective hiding of files, processes and network activity, as well as log tampering, providing authenticated backdoors, and enabling root access to non-privileged users.\n\nKernel extensions, also called kext, are used in macOS to load functionality onto a system similar to LKMs for Linux. Since the kernel is responsible for enforcing security and the kernel extensions run as apart of the kernel, kexts are not governed by macOS security policies. Kexts are loaded and unloaded through `kextload` and `kextunload` commands. Kexts need to be signed with a developer ID that is granted privileges by Apple allowing it to sign Kernel extensions. Developers without these privileges may still sign kexts but they will not load unless SIP is disabled. If SIP is enabled, the kext signature is verified before being added to the AuxKC.\n\nSince macOS Catalina 10.15, kernel extensions have been deprecated in favor of System Extensions. However, kexts are still allowed as \"Legacy System Extensions\" since there is no System Extension for Kernel Programming Interfaces.\n\nAdversaries can use LKMs and kexts to conduct Persistence and/or Privilege Escalation on a system. Examples have been found in the wild, and there are some relevant open source projects as well.

An exploit takes advantage of a bug or vulnerability in order to cause unintended or unanticipated behavior to occur on computer hardware or software. Rather than developing their own exploits, an adversary may find/modify exploits from online or purchase them from exploit vendors.\n\nIn addition to downloading free exploits from the internet, adversaries may purchase exploits from third-party entities. Third-party entities can include technology companies that specialize in exploit development, criminal marketplaces (including exploit kits), or from individuals. In addition to purchasing exploits, adversaries may steal and repurpose exploits from third-party entities (including other adversaries).\n\nAn adversary may monitor exploit provider forums to understand the state of existing, as well as newly discovered, exploits. There is usually a delay between when an exploit is discovered and when it is made public. An adversary may target the systems of those known to conduct exploit research and development in order to gain that knowledge for use during a subsequent operation.\n\nAdversaries may use exploits during various phases of the adversary lifecycle (i.e. Exploit Public-Facing Application, Exploitation for Client Execution, Exploitation for Privilege Escalation, Exploitation for Stealth, Exploitation for Credential Access, Exploitation of Remote Services, and Application or System Exploitation).\n\n## Reference: ATT&CK T1645 Compromise Client Software Binary\n**ATT&CK T1645 Compromise Client Software Binary (full record).** Adversaries may modify system software binaries to establish persistent access to devices. System software binaries are used by the underlying operating system and users over adb or terminal emulators.\n\nAdversaries may make modifications to client software binaries to carry out malicious tasks when those binaries are executed. For example, malware may come with a pre-compiled malicious binary intended to overwrite the genuine one on the device. Since these binaries may be routinely executed by the system or user, the adversary can leverage this for persistent access to the device.\n\n**Classification.** - Tactics: persistence\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- **System Partition Integrity**: Ensure that Android devices being used include and enable the Verified Boot capability, which cryptographically ensures the integrity of the system partition.\n- **Security Updates**: Install security updates in response to discovered vulnerabilities.\n- **Attestation**: Enable remote attestation capabilities when available (such as Android SafetyNet or Samsung Knox TIMA Attestation) and prohibit devices that fail the attestation from accessing enterprise resources.\n\n**Detection strategies and analytics.** - **Detection of Compromise Client Software Binary**\n  - For Android, detect Compromise Client Software Binary from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events. […]\n\n## Reference: ATT&CK T1646 Exfiltration Over C2 Channel\n**ATT&CK T1646 Exfiltration Over C2 Channel (full record).** Adversaries may steal data by exfiltrating it over an existing command and control channel.

[…]\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. […]"}]}

Exploitation occurs when an adversary takes advantage of a programming error in software, services, or the operating system to execute adversary-controlled code, often with the goal of weakening or disabling protections.\n\nVulnerabilities may exist in security tools such as antivirus, endpoint detection and response (EDR), firewalls, or other monitoring solutions. Adversaries may use prior reconnaissance or perform discovery activities (e.g., Software Discovery) to identify defensive tools present in an environment and target them for exploitation.\n\nSuccessful exploitation may allow adversaries to terminate security processes, disable protections, bypass enforcement mechanisms, or reduce the effectiveness of defensive controls. In some cases, vulnerabilities in cloud-based or SaaS infrastructure may also be leveraged to bypass built-in security boundaries or disrupt visibility and enforcement across environments.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: IaaS, Linux, macOS, SaaS, Windows\n\n**Detection strategies and analytics.** - **Detection of Defense Impairment**\n  - Detects suspicious interactions with security products followed by service crashes, unexpected restarts, driver unloads, telemetry gaps, or tamper-state changes.

Correlates local execution or network input with control degradation. […]\n\n## Reference: ATT&CK T1688 Safe Mode Boot\n**ATT&CK T1688 Safe Mode Boot (full record).** Adversaries may abuse Windows safe mode to disable endpoint defenses. Safe mode starts up the Windows operating system with a limited set of drivers and services. Third-party security software such as endpoint detection and response (EDR) tools may not start after booting Windows in safe mode. There are two versions of safe mode: Safe Mode and Safe Mode with Networking. It is possible to start additional services after a safe mode boot.\n\nAdversaries may abuse safe mode to disable endpoint defenses that may not start with a limited boot. Hosts can be forced into safe mode after the next reboot via modifications to Boot Configuration Data (BCD) stores, which are files that manage boot application settings.\n\nAdversaries may also add their malicious applications to the list of minimal services that start in safe mode by modifying relevant Registry values (i.e. Modify Registry). Malicious Component Object Model (COM) objects may also be registered and loaded in safe mode.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\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- **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\n**Detection strategies and analytics.** - **Detection Strategy for Safe Mode Boot Abuse**\n  - Abuse of safe mode via BCD modification, boot configuration utilities (bcdedit.exe, bootcfg.exe), and registry persistence under SafeBoot keys. Defender view: suspicious boot configuration changes correlated with registry edits that enable adversary persistence or disable defenses. […]\n\n## Reference: ATT&CK T1689 Downgrade Attack\n**ATT&CK T1689 Downgrade Attack (full record).** Adversaries may downgrade or use a version of system features that may be outdated, vulnerable, and/or does not support updated security controls. Downgrade attacks typically take advantage of a system’s backward compatibility to force it into less secure modes of operation.\n\nAdversaries may downgrade and use various less-secure versions of features of a system, such as Command and Scripting Interpreter or even network protocols that can be abused to enable Adversary-in-the-Middle or Network Sniffing. For example, PowerShell versions 5+ includes Script Block Logging (SBL), which can record executed script content. However, adversaries may attempt to execute a previous version of PowerShell that does not support SBL with the intent to impair defenses while running malicious scripts that may have otherwise been detected.\n\nAdversaries may similarly target network traffic to downgrade from an encrypted HTTPS connection to an unsecured HTTP connection that exposes network data in clear text. On Windows systems, adversaries may downgrade the boot manager to a vulnerable version that bypasses Secure Boot, granting the ability to disable various operating system security mechanisms.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: macOS, Windows, Linux\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- **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.** - **Detecting Downgrade Attacks**\n  - Detection of processes launching downgraded PowerShell versions (e.g., v2) or other legacy binaries that lack logging or security features. Correlates command-line arguments, process metadata, and version fields. […]\n\n## Reference: ATT&CK T1690 Prevent Command History Logging\n**ATT&CK T1690 Prevent Command History Logging (full record).** Adversaries may impair command history logging to hide commands they run on a compromised system. Various command interpreters keep track of the commands users type in their terminal so that users can retrace what they have done.\n\nOn Linux and macOS, 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 `HISTCONTROL` environment variable keeps track of what should be saved by the history command and eventually into the `~/.bash_history` file when a user logs out. `HISTCONTROL` does not exist by default on macOS, but can be set by the user and will be respected. The `HISTFILE` environment variable is also used in some ESXi systems.\n\nAdversaries may clear the history environment variable (`unset HISTFILE`) or set the command history size to zero (`export HISTFILESIZE=0`) to prevent logging of commands. Additionally, `HISTCONTROL` can be configured to ignore commands that start with a space by simply setting it to \"ignorespace\". `HISTCONTROL` can also be set to ignore duplicate commands by setting it to \"ignoredups\". In some Linux systems, this is set by default to \"ignoreboth\" which covers both of the previous examples. This means that \" ls\" will not be saved, but \"ls\" would be saved by history. Adversaries can abuse this to operate without leaving traces by simply prepending a space to all of their terminal commands.\n\nOn Windows systems, the `PSReadLine` module tracks commands used in all PowerShell sessions and writes them to a file (`$env:APPDATA\\Microsoft\\Windows\\PowerShell\\PSReadLine\\ConsoleHost_history.txt` by default). Adversaries may change where these logs are saved using `Set-PSReadLineOption -HistorySavePath {File Path}`. This will cause `ConsoleHost_history.txt` to stop receiving logs. […]\n\n## Reference: ATT&CK T1691 Block Operational Technology Message\n**ATT&CK T1691 Block Operational Technology Message (full record).** Adversaries may block messages between systems and devices in an OT/ICS environment to disrupt processes. Messages typically fall into two categories: (1) reporting messages that contain telemetry data about the current state of systems, devices, and processes and (2) command messages that contain instructions to control systems, devices, and processes. Both types of messages are critical for the proper functioning of industrial control processes and failure of the messages to reach their intended destinations could inhibit response functions or create an unsafe condition that could have physical impacts.\n\nAdversaries may block communications by either making modifications to software (System Firmware, Module Firmware, Hooking, and Rootkit) and services (Service Stop, Denial of Service) on systems and devices or by positioning themselves between systems and devices and intercepting and blocking the communications such as the case with an Adversary-in-the-Middle attack.\n\n**Classification.** - Tactics: inhibit-response-function\n- Platforms: Embedded, Windows, Linux\n\n**Sub-techniques.** - T1691.002 Reporting Message: Adversaries may block or prevent a reporting message from reaching its intended target.\n- T1691.001 Command Message: Adversaries may block a command message from reaching its intended target to prevent command execution. In OT networks, command messages are sent to provide instructions to control system devices.\n\n**Mitigations.** - **Out-of-Band Communications Channel**: Have alternative methods to support communication requirements during communication failures and data integrity attacks.\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 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.

Skeleton key works through a patch on an enterprise domain controller authentication process (LSASS) with credentials that adversaries may use to bypass the standard authentication system. Once patched, an adversary can use the injected password to successfully authenticate as any domain user account (until the the skeleton key is erased from memory by a reboot of the domain controller).

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. To perform proper validation, filters must receive plain-text credentials from the LSA. A malicious password filter would receive these plain-text credentials every time a password request is made.\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.** - **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\n**Detection strategies and analytics.** - **Detect Malicious Password Filter DLL Registration**\n  - Detects suspicious registration of new password filter DLLs into the authentication process.

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).

These factors typically include:\n\n**Detection strategies and analytics.** - **Detect Modification of Network Device Authentication via Patched System Images**\n  - Detects unauthorized modification of network device authentication by correlating OS image file changes, checksum mismatches, or memory verification failures with anomalous authentication events. Focus is on behaviors where patched images introduce hardcoded passwords or bypass native authentication. […]\n\n## Reference: ATT&CK T1556.005 Reversible Encryption\n**ATT&CK T1556.005 Reversible Encryption (full record).** An adversary may abuse Active Directory authentication encryption properties to gain access to credentials on Windows systems. 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.

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 Threat Intel Vendors**\n  - Much of this activity may have a very high occurrence and associated false positive rate, as well as potentially taking 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. (telemetry: )\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. […]\n\n## Reference: ATT&CK T1661 Application Versioning\n**ATT&CK T1661 Application Versioning (full record).** An adversary may push an update to a previously benign application to add malicious code. 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. […]\n\n## Reference: ATT&CK T1662 Data Destruction\n**ATT&CK T1662 Data Destruction (full record).** Adversaries may destroy data and files on specific devices or in large numbers to interrupt availability to systems, services, and network resources. Data destruction is likely to render stored data irrecoverable by forensic techniques through overwriting files or data on local and remote drives.\n\nTo achieve data destruction, adversaries may use the `pm uninstall` command to uninstall packages or the `rm` command to remove specific files. For example, adversaries may first use `pm uninstall` to uninstall non-system apps, and then use `rm (-f) <file(s)>` to delete specific files, further hiding malicious activity.\n\n**Classification.** - Tactics: impact\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 Data Destruction**\n  - For Android, detect Data Destruction from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

They may also be used as a component of malware to establish a reverse connection to an adversary-controlled system or service. Installation of remote access tools may also include persistence.\n\n**Classification.** - Tactics: command-and-control\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- **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 Remote Access Software**\n  - For Android, detect Remote Access Software by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

Vulnerabilities may be present in the applications, the services, the underlying operating system, or the kernel itself. Several well-known mobile device exploits exist, including FORCEDENTRY, StageFright, and BlueBorne. Furthermore, some exploits may be possible to exploit without any user interaction (i.e. zero-click exploits, see Exploitation for Client Execution), making them particularly dangerous. Mobile operating system vendors are typically very quick to patch such critical bugs, ensuring only a small window where they can be exploited.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Android, iOS\n\n**Mitigations.** - **Security Updates**: Install security updates in response to discovered vulnerabilities.\n- **Antivirus/Antimalware**: Mobile security products, such as Mobile Threat Defense (MTD), offer various device-based mitigations against certain behaviors.\n\n**Detection strategies and analytics.** - **Detection of Exploitation for Initial Access**\n  - For Android, detect Exploitation for Initial Access by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

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## Reference: ATT&CK T1078.003 Local Accounts\n**ATT&CK T1078.003 Local Accounts (full record).** Adversaries may obtain and abuse credentials of a local account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Local accounts are those configured by an organization for use by users, remote support, services, or for administration on a single system or service.\n\nLocal Accounts may also be abused to elevate privileges and harvest credentials through OS Credential Dumping. Password reuse may allow the abuse of local accounts across a set of machines on a network for the purposes of Privilege Escalation and Lateral Movement.\n\n**Classification.** - Tactics: stealth, persistence, privilege-escalation, initial-access\n- Platforms: Containers, ESXi, Linux, macOS, Network Devices, 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.** - **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. These factors typically include:\n- **Password Policies**: Set 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- **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 T1078.004 Cloud Accounts\n**ATT&CK T1078.004 Cloud Accounts (full record).** Valid accounts in cloud environments may allow adversaries to perform actions to achieve Initial Access, Persistence, Privilege Escalation, or Defense Evasion. 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. […]\n\n## Reference: ATT&CK T1080 Taint Shared Content\n**ATT&CK T1080 Taint Shared Content (full record).** Adversaries may deliver payloads to remote systems by adding content to shared storage locations, such as network drives or internal code repositories. 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. These solutions continuously monitor endpoints and systems for known malicious patterns and suspicious behaviors that indicate compromise. […]\n\n## Reference: ATT&CK T1082 System Information Discovery\n**ATT&CK T1082 System Information Discovery (full record).** An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture. Adversaries may use this information to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions. This behavior is distinct from Local Storage Discovery which is an adversary's discovery of local drive, disks and/or volumes.\n\nTools such as Systeminfo can be used to gather detailed system information. If running with privileged access, a breakdown of system data can be gathered through the `systemsetup` configuration tool on macOS. Adversaries may leverage a Network Device CLI on network devices to gather detailed system information (e.g. `show version`). On ESXi servers, threat actors may gather system information from various esxcli utilities, such as `system hostname get` and `system version get`.\n\nInfrastructure as a Service (IaaS) cloud providers such as AWS, GCP, and Azure allow access to instance and virtual machine information via APIs. Successful authenticated API calls can return data such as the operating system platform and status of a particular instance or the model view of a virtual machine.\n\nSystem Information Discovery combined with information gathered from other forms of discovery and reconnaissance can drive payload development and concealment.\n\n**Classification.** - Tactics: discovery\n- Platforms: ESXi, IaaS, Linux, macOS, Network Devices, Windows\n\n**Detection strategies and analytics.** - **System Discovery via Native and Remote Utilities**\n  - Detection of processes executing system environment inspection operations followed by access to OS configuration APIs or registry locations that expose OS version, architecture, patch level, or hardware characteristics. Defenders observe process execution retrieving system configuration metadata immediately after process startup. […]\n\n## Reference: ATT&CK T1083 File and Directory Discovery\n**ATT&CK T1083 File and Directory Discovery (full record).** Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system. Adversaries may use the information from File and Directory 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\nMany command shell utilities can be used to obtain this information. Examples include `dir`, `tree`, `ls`, `find`, and `locate`. Custom tools may also be used to gather file and directory information and interact with the Native API. Adversaries may also leverage a Network Device CLI on network devices to gather file and directory information (e.g. `dir`, `show flash`, and/or `nvram`).\n\nSome files and directories may require elevated or specific user permissions to access.\n\n**Classification.** - Tactics: discovery\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n\n**Detection strategies and analytics.** - **Recursive Enumeration of Files and Directories Across Privilege Contexts**\n  - Execution of file enumeration commands (e.g., 'dir', 'tree') from non-standard processes or unusual user contexts, followed by recursive directory traversal or access to sensitive locations.

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. […]\n\n## Reference: ATT&CK T1546.001 Change Default File Association\n**ATT&CK T1546.001 Change Default File Association (full record).** Adversaries may establish persistence by executing malicious content triggered by a file type association. When a file is opened, the default program used to open the file (also called the file association or handler) is checked. File association selections are stored in the Windows Registry and can be edited by users, administrators, or programs that have Registry access or by administrators using the built-in assoc utility. Applications can modify the file association for a given file extension to call an arbitrary program when a file with the given extension is opened.\n\nSystem file associations are listed under `HKEY_CLASSES_ROOT\\.[extension]`, for example `HKEY_CLASSES_ROOT\\.txt`. The entries point to a handler for that extension located at `HKEY_CLASSES_ROOT\\\\[handler]`. The various commands are then listed as subkeys underneath the shell key at `HKEY_CLASSES_ROOT\\\\[handler]\\shell\\\\[action]\\command`. For example:\n\n* `HKEY_CLASSES_ROOT\\txtfile\\shell\\open\\command`\n* `HKEY_CLASSES_ROOT\\txtfile\\shell\\print\\command`\n* `HKEY_CLASSES_ROOT\\txtfile\\shell\\printto\\command`\n\nThe values of the keys listed are commands that are executed when the handler opens the file extension.

[…]\n\n## Reference: ATT&CK T1546.002 Screensaver\n**ATT&CK T1546.002 Screensaver (full record).** Adversaries may establish persistence by executing malicious content triggered by user inactivity. Screensavers are programs that execute after a configurable time of user inactivity and consist of Portable Executable (PE) files with a.scr file extension. The Windows screensaver application scrnsave.scr is located in `C:\\Windows\\System32\\`, and `C:\\Windows\\sysWOW64\\` on 64-bit Windows systems, along with screensavers included with base Windows installations.\n\nThe following screensaver settings are stored in the Registry (`HKCU\\Control Panel\\Desktop\\`) and could be manipulated to achieve persistence:\n\n* `SCRNSAVE.exe` - set to malicious PE path\n* `ScreenSaveActive` - set to '1' to enable the screensaver\n* `ScreenSaverIsSecure` - set to '0' to not require a password to unlock\n* `ScreenSaveTimeout` - sets user inactivity timeout before screensaver is executed\n\nAdversaries can use screensaver settings to maintain persistence by setting the screensaver to run malware after a certain timeframe of user inactivity.\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- **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. […]\n\n## Reference: ATT&CK T1546.003 Windows Management Instrumentation Event Subscription\n**ATT&CK T1546.003 Windows Management Instrumentation Event Subscription (full record).** Adversaries may establish persistence and elevate privileges by executing malicious content triggered by a Windows Management Instrumentation (WMI) event subscription. 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.

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).

Process injection is a method of executing arbitrary code in the address space of a separate live process. Running code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via process injection may also evade detection from security products since the execution is masked under a legitimate process.\n\nBoth Android and iOS have no legitimate way to achieve process injection.

The behavior chain includes: (1) suspicious process execution on a domain controller followed by (2) user account creation event (Event ID 4720) on the same host.\n- Analytic 0007: Adversary with access to domain management tools (e.g., `realmd`, `samba-tool`, `ldapmodify`) creates a new domain user via command-line utilities. Behavior chain: LDAP command or script triggers → user entry added in AD via Kerberos/LDAP traffic.\n- Analytic 0008: macOS clients joined to AD via LDAP may script account provisioning via `dsconfigad`, `dscl`, or LDAP scripts. Detection occurs when such tools run on a domain-joined system, followed by authentication attempts by a previously unseen account.\n\n## Reference: ATT&CK DET0004 Detection Strategy for Hijack Execution Flow using Path Interception by PATH Environment Variable.\n**Detects.** - T1574.007 Path Interception by PATH Environment Variable\n\n**Analytics.** - Analytic 0009: Abnormal modification of the PATH environment variable or registry keys controlling system paths, combined with execution of binaries named after legitimate system tools from user-writable directories.\n- Analytic 0010: User modification of the $PATH environment variable in shell configuration files or direct runtime PATH changes, followed by execution of binaries from user-controlled directories.\n- Analytic 0011: Modification of PATH or HOME environment variables through shell config files, launchctl, or /etc/paths.d entries, combined with process execution from attacker-controlled directories.

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 (e.g., by using `malloc`) then invoking that memory with `PTRACE_SETREGS` to set the register containing the next instruction to execute. Ptrace system call injection can also be done with `PTRACE_POKETEXT`/`PTRACE_POKEDATA`, which copy data to a specific address in the target process's memory (e.g., the current address of the next instruction).\n\nPtrace system call injection may not be possible when targeting processes with high-privileges, and on some systems those that are non-child processes.\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 ptrace system call injection may also evade detection from security products since the execution is masked under a legitimate process.\n\n## Reference: ATT&CK DET0076 Behavioral Detection of Visual Basic Execution (VBS/VBA/VBScript)\n**Detects.** - T1059.005 Visual Basic\n\n**Analytics.** - Analytic 0209: Detects execution of VB-based scripts or macros (VBS/VBA/VBScript) through cscript.exe/wscript.exe, Office-based process chains, or HTA usage.

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.

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 T1568.001 Fast Flux DNS\n**ATT&CK T1568.001 Fast Flux DNS (full record).** 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. This technique uses a fully qualified domain name, with multiple IP addresses assigned to it which are swapped with high frequency, using a combination of round robin IP addressing and short Time-To-Live (TTL) for a DNS resource record.\n\nThe simplest, \"single-flux\" method, involves registering and de-registering an addresses as part of the DNS A (address) record list for a single DNS name. These registrations have a five-minute average lifespan, resulting in a constant shuffle of IP address resolution.\n\nIn contrast, the \"double-flux\" method registers and de-registers an address as part of the DNS Name Server record list for the DNS zone, providing additional resilience for the connection. With double-flux additional hosts can act as a proxy to the C2 host, further insulating the true source of the C2 channel.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Linux, macOS, Windows, ESXi\n- Sub-technique of: T1568 Dynamic Resolution - Adversaries may dynamically establish connections to command and control infrastructure to evade common detections and remediations.

Correlate with process lineage (e.g., Office apps spawning abnormal DNS lookups). (telemetry: WinEventLog:Sysmon:EventCode=3, 22, WinEventLog:Security:EventCode=1)\n  - Monitor resolver logs and auditd events for domains resolving to a rotating set of IPs within very short TTL intervals. Correlate high query rates from non-browser applications (e.g., python, curl). […]\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.

A IP and/or port number calculation can be used to bypass egress filtering on a C2 channel.\n\nOne implementation of DNS Calculation is to take the first three octets of an IP address in a DNS response and use those values to calculate the port for command and control traffic.\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. This may be achieved by using malware that shares a common algorithm with the infrastructure the adversary uses to receive the malware's communications.\n\n**Detection strategies and analytics.** - **Detection Strategy for Dynamic Resolution through DNS Calculation**\n  - Monitor DNS query results where subsequent connections use derived or unusual port numbers not explicitly resolved, especially when tied to suspicious processes. Correlate Sysmon DNS logs (Event ID 22) with process creation and socket activity. (telemetry: WinEventLog:Sysmon:EventCode=3, 22, WinEventLog:Sysmon:EventCode=1)\n  - Inspect resolver and audit logs for processes initiating outbound connections to ports calculated from DNS response IPs. Abnormal ephemeral port usage shortly after DNS queries can indicate DNS calculation behavior. (telemetry: auditd:SYSCALL:connect, linux:syslog:DNS response IPs followed by connections to non-standard calculated ports)\n  - Use unified logs to detect unusual DNS responses correlated with subsequent connections to calculated or non-standard ports. Monitor non-browser apps making repeated outbound connections that deviate from expected patterns. […]"}]}

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.

[…]\n\n## Reference: ATT&CK T1027.018 Invisible Unicode\n**ATT&CK T1027.018 Invisible Unicode (full record).** Adversaries may abuse invisible or non-printing Unicode characters to conceal malicious content within files, scripts, or text. By inserting characters that do not visibly render, adversaries may hide data, alter how content is interpreted, or make malicious code appear as benign text or whitespace. Adversaries may encode these malicious payloads, using binary, Base64, or custom schemes, to be reconstructed at runtime through scripting features such as JavaScript Proxy traps, `eval`, or other dynamic execution methods. This technique enables adversaries to evade visual inspection and basic static analysis by hiding malicious encoded content in innocuous text.\n\nUnicode is a standardized character encoding model that assigns a unique numerical value, known as a code point, to every character across writing systems, enabling consistent text representation across platforms, applications, and languages. Code points are represented as `U+` followed by a hexadecimal value and may be encoded using formats such as `UTF-8` or `UTF-16`. Adversaries may abuse the valid code points in Unicode that are not visibly rendered but still take up bytes, such as zero-width spaces, variation selectors, or bidirectional formatting controls, to conceal malicious payloads.\n\nAdversaries may additionally exploit Private Use Area (PUA) characters, a range of code points reserved for custom assignment. PUA characters that are not defined by a font or application are typically rendered blank.\n\nUnicode characters may also be leveraged in support of other techniques such as Phishing, Right-to-Left Override, or User Execution. For example, some adversaries may embed artificial intelligence (AI) prompt injections using invisible Unicode characters in emails or documents that appear benign when processed by AI systems.\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.

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. […]\n\n## Reference: ATT&CK T0869 Standard Application Layer Protocol\n**ATT&CK T0869 Standard Application Layer Protocol (full record).** 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. 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.

Brute Force I/O may be achieved by changing either a range of I/O point values or a single point value repeatedly to manipulate a process function. The adversary's goal and the information they have about the target environment will influence which of the options they choose. In the case of brute forcing a range of point values, the adversary may be able to achieve an impact without targeting a specific point. In the case where a single point is targeted, the adversary may be able to generate instability on the process function associated with that particular point.\n\nAdversaries may use Brute Force I/O to cause failures within various industrial processes.

The adversary may drop or create malware, tools, or other non-native files on a target system to accomplish this, potentially leaving behind traces of malicious activities. Such non-native files and other data may be removed over the course of an intrusion to maintain a small footprint or as a standard part of the post-intrusion cleanup process.\n\nData destruction may also be used to render operator interfaces unable to respond and to disrupt response functions from occurring as expected. An adversary may also destroy data backups that are vital to recovery after an incident.\n\nStandard file deletion commands are available on most operating system and device interfaces to perform cleanup, but adversaries may use other tools as well.

For example, adversaries may communicate with victims (via Phishing for Information, Phishing, or Internal Spearphishing) while impersonating a known sender such as an executive, colleague, or third-party vendor. Established trust can then be leveraged to accomplish an adversary’s ultimate goals, possibly against multiple victims.\n\nIn many cases of business email compromise or email fraud campaigns, adversaries use impersonation to defraud victims -- deceiving them into sending money or divulging information that ultimately enables Financial Theft.\n\nAdversaries will often also use social engineering techniques such as manipulative and persuasive language in email subject lines and body text such as `payment`, `request`, or `urgent` to push the victim to act quickly before malicious activity is detected. These campaigns are often specifically targeted against people who, due to job roles and/or accesses, can carry out the adversary’s goal.  \n\nImpersonation is typically preceded by reconnaissance techniques such as Gather Victim Identity Information and Gather Victim Org Information as well as acquiring infrastructure such as email domains (i.e. Domains) to substantiate their false identity.\n\nThere is the potential for multiple victims in campaigns involving impersonation.

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## Reference: ATT&CK T0849 Masquerading\n**ATT&CK T0849 Masquerading (full record).** Adversaries may use masquerading to disguise a malicious application or executable as another file, to avoid operator and engineer suspicion. 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. The mismatch -- name says one thing, binary integrity says another -- is the defining signal. OT operational-fidelity gate: Alert only when execution violates an approved signer/hash/path/parent/process or tool allowlist, or originates from an unauthorized user/tool, and is tied to an OT asset or follow-on OT-relevant action. […]\n\n## Reference: ATT&CK T0851 Rootkit\n**ATT&CK T0851 Rootkit (full record).** Adversaries may deploy rootkits to hide the presence of programs, files, network connections, services, drivers, and other system components. Rootkits are programs that hide the existence of malware by intercepting and modifying operating-system API calls that supply system information. Rootkits or rootkit-enabling functionality may reside at the user or kernel level in the operating system, or lower.\n\nFirmware rootkits that affect the operating system yield nearly full control of the system. While firmware rootkits are normally developed for the main processing board, they can also be developed for the I/O that is attached to an asset. Compromise of this firmware allows the modification of all of the process variables and functions the module engages in. This may result in commands being disregarded and false information being fed to the main device. By tampering with device processes, an adversary may inhibit its expected response functions and possibly enable Impact.\n\n**Classification.** - Tactics: evasion, inhibit-response-function\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- **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\n**Detection strategies and analytics.** - **Detection of Rootkit**\n  - Periodic or event-triggered integrity verification identifies a discrepancy between a field device's self-reported diagnostic state and an independently verified hardware/firmware fingerprint, indicating the device's reporting layer has been compromised. MITRE explicitly notes firmware/module rootkits 'can also be developed for the Input/Output (I/O) that is attached to an asset.'. […]\n\n## Reference: ATT&CK T0852 Screen Capture\n**ATT&CK T0852 Screen Capture (full record).** Adversaries may attempt to perform screen capture of devices in the control system environment. Screenshots may be taken of workstations, HMIs, or other devices that display environment-relevant process, device, reporting, alarm, or related data. These device displays may reveal information regarding the ICS process, layout, control, and related schematics. In particular, an HMI can provide a lot of important industrial process information. Analysis of screen captures may provide the adversary with an understanding of intended operations and interactions between critical devices.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded, Windows, Linux\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 Screen Capture**\n  - Real-time monitoring identifies execution of screenshot utilities (scrot, import, xwd) on an Industrial Control System (ICS) Linux Human-Machine Interface (HMI), from a User Identifier (UID) that does not normally perform display operations. OT operational-fidelity gate: Do not alert on novelty, scan/read volume, or enumeration alone. Alert when the source role is not authorized for discovery/polling and the target scope, address/tag range, protocol, or rate deviates from the established operational baseline. […]\n\n## Reference: ATT&CK T0858 Change Operating Mode\n**ATT&CK T0858 Change Operating Mode (full record).** Adversaries may change the operating mode of a controller to gain additional access to engineering functions such as Program Download. Programmable controllers typically have several modes of operation that control the state of the user program and control access to the controllers API. Operating modes can be physically selected using a key switch on the face of the controller but may also be selected with calls to the controllers API. 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: execution, evasion\n- Platforms: Embedded\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- **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 T0859 Valid Accounts\n**ATT&CK T0859 Valid Accounts (full record).** Adversaries may steal the credentials of a specific user or service account using credential access techniques. 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. […]"}]}

This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\n- **Validate Program Inputs**: Devices and programs designed to interact with control system parameters should validate the format and content of all user inputs and actions to ensure the values are within intended operational ranges. These values should be evaluated and further enforced through the program logic running on the field controller.\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- **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- **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\n- **Detection of Unauthorized Command Message**\n  - Real-time monitoring identifies a Windows process generating Industrial Control System (ICS) command messages to field device tags representing physical outputs, from a process that is not the recognized Supervisory Control and Data Acquisition (SCADA) or Distributed Control System (DCS) control application, targeting safety-critical output tags.

This first description of a SCA explained how the mere observation of the duration of computations could allow an attacker to retrieve the secret key. The attack was then improved and extended to other cryptosystems [ 38, 6, 12, 49 ]. In 1999 Kocher et al. described what they called “ dpa\n\n1 1\n\n1\n\nD ifferential\n\nP ower A nalysis. ” [32]. This new attack used the power consumption instead to the duration but yielded the same result: the retrieval of the secret key. The process of this latter attack is relatively simple: a large number of cryptographic operations are monitored and the cipher text stored together with the electric consumption. Then guesses were made of some parts of the secret key, which were confirmed or or not by a statistical processing the data. Other attacks against various cryptosystems were based on this method\n\n[ 5, 42, 18 ]. Countermeasures soon appeared to protect systems based on a strong algebraic structure [ 2, 20, 47, 25 ]. At he protection of opposite symmetric cryptosystems often consisted in introducing some randomization either in the computing process or power consumption to prevent the statistical processing of the acquired data. However “counter-countermeasures” also appeared [19]. Some other protection schemes were designed\n\n[ 26, 10 ]. An interesting and apparently efficient countermeasure is the WDDL 2 2\n\n2\n\nW ave\n\nD ynamic D ifferential L ogic. [46] which duplicates each signal in the circuit so that whatever the value is, one of the lines will toggle. This countermeasure was enhanced by an improved routing of related signals\n\n[11], which reduces the differences between the power consumptions of a ’1’ and a ’0’. Asynchronous circuits, the history of which dates back to 1950, are nowadays increasingly considered as a viable alternative to classical synchronous designs. Indeed they feature some very useful properties such as flexibility, robustness, high speed and low power. This article brings another good reason to consider asynchronous designs: a greater resistance against side-channel attacks. Some industrial applications of asynchronous ASIC and FPGA begin to appear both in the academic world [ 28, 29, 44 ] and in the industry [1]. At the same time synchronous circuits are suffering from problems arising from the distribution of the clock signal through the IC and the excessive power consumption (and thus dissipation!). As an asynchronous circuit has no centralized clock, the problems associated with the clock distribution, clock skew and power consumption do not exist. In addition this circuits offers advantages like:\n\n•\n\naverage-time performance,\n\n•\n\nlower electromagnetic radiation,\n\n•\n\nbetter robustness towards variations of the power voltage,\n\n•\n\nbetter robustness towards fabrication process variations [31],\n\n•\n\nbetter composability and modularity because of the simple handshake interfaces and the local timing [39] and\n\n•\n\nbetter scrambling of the side-channel information [ 30, 16, 41 ]. Asynchronous circuits thus seem to be a viable alternative which would remove these limiting factors [35]. Due to these advantages, there has been a resurgence of interest in asynchronous design, especially in the reprogrammable field. There have been several recent successful design projects such as ASPRO-216 [36], AES crypto-processor [4], many of Philips designs targeting low power [ 3, 21 ], projects focused on designing an asynchronous FPGA from a synchronous one, like MONTAGE [14] and PGA-STC [27] or targeting asynchronous application-specific FPGAs, locally synchronous, like GALSA [9] and STACC [33] or completely asynchronous like PAPA [ 43, 45 ], and other recent works [ 15, 8, 7, 17, 24 ]. PGA-STC was developed to implement two-phase bundled-data systems such as micro pipelines, GALSA for massively parallel computing architecture, STACC for reconfigurable computation and PAPA was mainly created and optimized for pipe-lined processes. This article describe the design of the PLB 3 3\n\n3\n\nP rogrammable L ogic B lock. of a new asynchronous FPGA with security as the main requirement, even at the expense of performance. Indeed in the particular case of cryptography performance is second to security even if it cannot be ignored. The FPGA must be able to implement various styles of asynchronous protocols and different representations of data so as to enable comparisons between these representations and protocols as for their ability to thwart the side-channel attacks. Section 2 describes the representation of data and the different asynchronous protocols used in the FPGA. We also discuss their suitablity for trusted computing. Section 3 shows the construction of the PLB to implement the 4-phase protocol using both binary and ternary representations of data. Section 4 shows the necessary additions to the PLB to accommodate the 2-phase protocols. Section 5 shows how the FPGA is programmed. Finally section 6 concludes the article. 2 Asynchronous Representation of Signals\n\nAs opposed to synchronous data, whose validity is guaranteed by the timing of some global “clock” signal, the asynchronous computations are synchronized by the availability of data and, when necessary, by a Request/Acknowledge handshake signalling. A formal description of delay insensitive representation of data can be found in [48]. In the Q uasi- D elay I nsensitive (QDI) protocols the request is carried by the data itself. This allows to obtain a reliable design, independent of the routing. The data are transmitted together with the availability information and thus a logic signal or, shorter a “ signal ”, must be represented by more than a single electrical signal or, shorter, a “ wire ’’ 4 4\n\n4\n\nIf one could work with non-standard electrical levels, a representation on a single wire per signal would be acceptable in some cases but we shall restrict ourselves in the following pages to standard CMOS levels: and.. In this article, a wire is able to take one of two values, which we denote 0 and 1 regardless of their actual electric implementation. In order to avoid glitches, a sufficient condition is that given a signal\n\nrepresented by wires, the transmission of a new value of must consist in\n\nexactly one of the wires changing its electrical state. This means that the number of wires is greater than or equal to the number of the states of. As silicon and routing is a precious resource, the number of wires representing a given signal will thus be equal to the number of possible values of this signal. The most frequently used kind of signal is the binary signal, which carries a { ‘1’, ‘0’ } information. Such a signal is encoded with 2 wires. This representation is called “ Dual-Rail ” or “ 1-out-of-2 ”. However ternary signals, which carry a { ‘0’, ‘1’, ‘2’ } information, can also be thought of. Such a signal is represented by 3 wires and one speaks of “ 1-out-of-3 ” representation. This representation is more compact than the 1-out-of-2 as for arithmetic: 6 wires in 1-out-of-2 represent 3 1-out-of-2 signals which can take 8 valid values, compared to two 1-out-of-3 signals, which can take 9 valid values. However due to the greater complexity of gates in 1-out-of-3 representation, the binary signals are most of the time preferred. An asynchronous design may need additional signals, which are specialized to synchronisation. These signal carry no data information and can thus be coded on a single wire. They will be referred to as Acknowledge signals. The inputs of the gates which receive such a signal will be denoted and those driving these signals will be called. 2.1 Asynchronous Protocols\n\nThere are two main families of QDI asynchronous communication protocols, which differ by the nature of the signalling information: the 2-phase protocols and the 4-phase protocols. 2.1.1 4-Phase Protocol\n\nUnder a 4-phase protocol, valid values of a signal are separated by a special value, denoted. The transmission of a value from an emitter to a receiver proceeds as follows:\n\nEmitter\n\nReceiver\n\n1\n\nsends\n\n2\n\nacknowledges\n\n3\n\nsends\n\n4\n\nacknowledges\n\nFor instance, if a signal is represented by wires, the\n\nvalue will be implemented as the -tuple while the value will be represented by. This particular kind of 4-phase protocol is named “ wchb ’’ 5 5\n\n5\n\nW eak\n\nC ondition H alf B uffer. in [ 37, Sec. 2.3.1] and as\n\ndpl 6 6\n\n6\n\nD ual- R ail P recharge L ogic\n\namong the secure computing community [34]. 2.1.2 2-Phase Protocols\n\nUnder a 2-phase protocol, no special value is used to separate valid ones. The transmission of a value from an emitter to a receiver proceeds as follows:\n\nEmitter\n\nReceiver\n\n1\n\nsends\n\n2\n\nacknowledges\n\nIn this article we will describe the implementations of two 2-phase protocols:\n\n2-phase-edge protocol:\n\na signal, which can take values is represented by wires and the arrival of a new value is signalled by wire\n\ntoggling or. Note that the instantaneous values of the wires is not significant under this protocol: only the toggles are significant. 2-phase-ledr protocol:\n\na signal is represented by two wires: and. The arrival of a new value, is signalled by one of and toggling\n\nor and the value is given by. Note that the requirement that any change of the value of the signal be implemented by the toggling of exactly 1 wire limits the 2-phase-ledr protocol to binary signals. Remark 1\n\nThe 4-phase protocol can be considered as a 2-phase protocol in which all “valid” values are followed by a dummy value and in which the gates return to the value as soon as all inputs have received the value. The\n\n2-phase protocols are thus inherently twice faster as the 4-phase ones. This is especially important in a FPGA, in which the routing delays are often the limiting factor of the speed of the system. However, even if twice faster, they lead to much more complex gates than the\n\n4-phase ones. 2.2 Initialization of the System\n\nAt the initial time of the system’s operation, all gates must be reset to a known, deterministic value. (This is also true for synchronous systems even if some flip-flops sometimes need no initialization.)\n\nThe requirement of a known, deterministic value, implies no specific value to the wires. However the simplest initialization, which we shall use in this article, consists in initializing all gates so that all wires be set to 0. The consequence of this initialization is that the parity of the Hamming weight of any signal is 0 just after reset, which implies that its parity is even. The relevant property just after RESET is thus that:\n\n•\n\nunder a 4-phase protocol an value is thus output by all gates and\n\n•\n\nunder a 2-phase protocol the parity of the Hamming weight of the outputs of any gate is 0. 2.3 Request Signalling\n\nThe Request event is coded into the data of the QDI protocol itself; a request corresponds to a change of one of the wires encoding the signal. A gate will be ready to perform its computation when each of its input have received a request and when all gates using its output have acknowledged the last value sent. If performance were the major requirement this would not be true: for instance, a AND gate could perfectly output a ‘0’ as soon as one of its inputs has received a ‘0’. But such an early evaluation would occur only when some input(s) receive a ‘0’ and never when all receive ‘1’. This difference in timing could potentially leak some information about the computations being performed to a malevolent observer. Thus such “early evaluation” will never be allowed in a secured circuit and computations will always be performed upon the\n\nrendez-vous of all data and Acknowledge inputs. As the arrival of a new value is always signalled by a single wire changing value, the parity of the Hamming weight of any signal changes each time a new value is transmitted. Under a two-phase protocol, a gate will be ready to compute its output when all its inputs show a parity opposed to the current output parity. Under a 4-phase protocol a gate is ready to compute as soon as each input has left then state. As\n\nis coded as is has an even parity while any valid value, signalled by a single wire at 1, has an even parity. The behaviour of the gates under a 4-phase protocol is thus coherent with the one of the gates under 2-phase protocols. This will be useful for the design of the FPGA. 2.4 Acknowledge Signalling\n\nThe Acknowledge signal consists of a single wire, carrying a {, ack } under a 4-phase protocol or an { odd, even } “phase” information, under a 2-phase protocol. Given the “parity” property of the signals, the Acknowledge signal is computed as the XOR of all wires carrying the output signal. An OR gate would be enough under a\n\n4-phase protocol."}]}

When the output of a gate is sent to more than one gate,,,…, a rendez-vous is computed to combine the synchronization signals coming from the into a single signal, fed to. 2.5 C-Element\n\nThe C-element is the gate which implements the rendez-vous of signals. It has an arbitrary number of input wires, denoted,,…,, and a single output, whose equations are:\n\n(1)\n\nEq. 2 shows an equivalent form of Eq. 1. (2)\n\nWhere and are respectively the AND and OR operators. ‘0’ ‘1’\n\nFigure 1: C-element implemented with a MUX. Fig. 1 depicts the implementation of a C-element derived form Eq. 2, using a multiplexer (MUX), which we use in out FPGA. In an FPGA the C-element can be implemented in many ways. A -input C-element can be implemented in -input lut, provided the output of the lut can be fed back to one of the inputs. If, the MUX selects the AND gate, which will output 1 if and only if. When this condition becomes true, the output of the MUX becomes 1 and the output of the OR is selected to be sent to instead of the one of the AND. As, the output is stable at 1. The output remains 1 until all inputs are back to 0. Mutatis mutandis\n\nthe same proof shows that the output of the gate comes back to 0 when all inputs are 0 and that this value is stable until all inputs are 1 again. Thus the gate correctly implements the rendez-vous with no glitch. 2.6 Asynchronous Computation & Security\n\n2.6.1 Timing Attack\n\nAs each gate always waits for every input to be ready before computing its result, the duration of the computations is independent of the data. However a dependency can be generated if the lengths of the wires which implement a signal are different, thus generating different propagation times for each value of. Thus the following necessary condition must hold: for any pair of gates\n\n, connected by a signal, composed of wires:\n\n•\n\nunder the 4-phase protocol, the propagation time of the transition from to any value and of the transition from any valid value to\n\nto must be independent of the value;\n\n•\n\nunder a 2-phase protocol, the rising and falling times of any output wire must be equal and independent from the former and next value of the signal. As the condition must be fulfilled by any signal routed through the FPGA, this implies that:\n\n•\n\nin any routing channel, all wires must have the same length and the same capacity with respect to or,\n\n•\n\nfor any pair of wires in two routing channels connected by a switchbox, the propagation time through the switchbox must be the same for all possible pairs,\n\n•\n\nfor any input of a PLB, the propagation time from the network to the processing elements must be uniform,\n\n•\n\nfor any output, the propagation time to the routing network must be uniform. If all these conditions are satisfied and if all PLB process information at the same speed the timing attack\n\n[ 23, 38, 6, 12, 49 ]\n\nis impossible. 2.6.2 Measurement of Power Consumption\n\nUnder the 4-phase protocol, two valid values are separated in time by a value, implemented as all wires at 0. The transition from to a valid value consist in a rising edge\n\nof wire and the return to is the opposite falling transition. In order to thwart these attacks the power consumption must be the same for the rising edge of any of the wire which compose a signal and also for their falling edges. This condition implies that lengths of the through the routing network be the same. The necessary conditions to thwart the timing attack are also necessary here but, in addition the resistances of the output transistors must be equal. 3 4-Phase Protocol\n\nThis protocol is the simplest of all three because the instantaneous values of the wires composing any signal are sufficient to determine the value of this signal. We will implement the gates with:\n\n•\n\nfrom 1 to 6 inputs, including the signals, and\n\n•\n\nfrom 2 to 4 outputs, not including the signals. 3.1 Encoding of Signals\n\nACK ’0’ ’0’ ’0’ ’1’ ’1’\n\nFigure 2: 4-Phase Protocol. Though it is not the only possible one, we shall use the one of Eq. 3\n\nfor a signal in the rest of this article:\n\n(3)\n\nThe occurrence of the “ ” forbidden state will always signal either a malfunction or an attack against the system. Fig. 2 depicts the succession of values on a signal, represented by 2 wires, and, when present, the associated transmissions of the ACK signal by the receiver back to the transmitter. 3.2 1-out-of-2,2-input Gates\n\nLet a two-variable Boolean function. Its output is a 1-out-of-2 signal represented by two wires and. We denote respectively and\n\nthe functions computing the values of each wire. Fig. 3 depicts the minimal structure of a PLB necessary to implement in the most general way a gate with 2 binary inputs. Three signals enter the gate: 2 data signals and, respectively implemented by the and pairs of wires, and, the synchronization signal. The output value  is implemented by two, respectively computing the and\n\nwires. Eq. 4 shows the equations of the outputs. In this equation,\n\n(4)\n\nL.U.T. L.U.T. Figure 3: Minimal PLB for 4-phase, 2-input gates. The “memory effect” implied by Eq. 4 is implemented by sending each of\n\nand to an input of the lut which drives it. Thus the minimal practical size for the lut is 64 bits, which can implement any 6-bit 1-bit function. As there are two output bits the minimal size of the PLB is 2 lut. Even if an OR gate would be enough, the signal is computed by a XOR gate (See\n\n2.4). As the inputs to the lut are the same, with the exception of the feedback wires, there can be a single connection box to the routing network, which will divide by 2 the total size of the connection boxes. Fig. 3 shows the minimal structure of the PLB, which allows to implement 2-input gates with synchronization. Remark 2\n\nIn Eq. 3, each wire of and is loaded with exactly the same number of inputs, as it is necessary to achieve the indiscernability of signals for a malevolent observer. 3.3 1-out-of-2, 3-input Gates\n\nEq. 4 can be immediately modified into Eq. 5 to add a third input term and the new equation shows that we need a 7-input lut with one feedback. (5)\n\nAs the 3-input gates need 6 inputs for a 3-variable function, they cannot be implemented in the structure of Fig. 3, on which each has 5 inputs from the routing network and 1 feedback input. As it is not realistic to use two because of the number of programming points ( bits), we separate the rendez-vous + computation function from the\n\nmemory function and introduce a specific component: the memory point. C C\n\nFigure 4: Memory Point. Fig. 4 depicts the memory point, which consists in a pair of C-elements, together with a XOR gate, which computes the signal. Two MUX, under control of a single programming point, allow to bypass the C-elements. It will be useful when implementing the 2-phase protocols. M M\n\nFigure 5: Binary 3-input gate with 4-phase protocol. Fig. 5 depicts the schematic of the 2-input 1-out-of-3 gate. The ancillary “return to ” function is implemented by a specialized 6-input OR gate while the are programmed to compute the\n\nrendez-vous and the functions and. Remark 3\n\nNote that it is much better use of the lut than the one implied by Fig. 3, in which all bits corresponding to the feedback input set to 1 are filled with ’1’ to implement the inclusive OR of all 4 input bits. The 4lut PLB can implement two independent 3-input, 1-out-of-2 functions. Ex: a full-adder. Remark 4\n\nThe wiring depicted by Fig. 5 can handle any gate the inputs of which sum up to 6 wires (Ex: one + one 1-out-of-2 input + one 1-out-of-3 input; two, two 1-out-of-2 inputs, etc…). Remark 5\n\nThe feed-back and the associated MUX at the inputs of lut could be removed. However they will be useful later for the implementation of the 2-phase-ledr protocol. 3.4 1-out-of-3, 2-input Gates\n\nM M\n\nFigure 6: Structure of PLB needed to implement a ternary 2-input gate. Just as the 1-out-of-2, 3-Input Gates, the 1-out-of-3, 2-input gates need 6 inputs but they need three outputs, each of them equipped with a memory point. Strictly speaking, a 1-out-of-3 gate needs three lut, each of them implementing one of the functions. However as most of the gates in a design will still be binary, the PLB features four. One of them will remain unused and filled with 0 when implementing a 1-out-of-3 gate. The computation of the signal needs some specialized hardware. Fig. 6 depicts the new PLB needed for a 2-input 1-out-of-3 gate, with the supplementary devices gate in a grey rectangle:\n\n•\n\na MUX, controlled by a programming point, which allows to use the PLB either as two separate 2-binary input, binary output gates or a single combined gate and\n\n•\n\na single XOR gate which computes the XOR of all four outputs of the memory points. For the same reason of compatibility with the binary gates, the inputs to the pairs of\n\nlut are split into two groups. The load to each of the 12 input wires is exactly the same, thus equalizing the power consumptions of all possible transitions on inputs. Remark 6\n\nThe OR gates which compute the “return to ” signal are not grouped but will compute output the same value as their input are the same. 3.5 Conclusion as for the 4-Phase Protocol\n\nIn order to implement 2- and 3-inputs gates under the 4-phase protocol, the PLB must at least consist of four, named,, and. One input of each lut can be replaced with a feedback signal equal to the output pin. The schematic depicted on Fig. 6 is general: it can implement any gate with:\n\n•\n\ninputs consisting in any combination of 6 wires or less, including the signals, and\n\n•\n\noutputs consisting of any combination of 4 wires, not counting the signals: 2 binary outputs, with separate signals, 1 ternary output with a single acknowledge-out signal or 1 quaternary output with an signal. 4 2-Phase Protocols\n\n4.1 Phase of a Signal\n\nUnder the 2-phase protocols valid values of a signal are not separated by “ ” markers. However, as the arrival of a new value (possibly identical to the preceding one) is indicated by the toggling a exactly one wire, the parity of the Hamming weight of the wires which represent a signal toggles at each new data. In the following pages, the phase of the signal, denoted “ ”, is by definition, the parity of the Hamming weight of the wires representing. Remark 7\n\nFor Acknowledge signals, which consist in a single wire, the phase is equal to the value of the wire itself. The name of an Acknowledge signal will thus be used instead of. At the beginning of the computation, all wires are set to a known value. 2-phase protocols require that, after initialization and before any computation is started, the parities of all signals be the same, say even. A simple way of ensuring this even parity is to initialize all wires to 0. As the phase of a signal toggles with every new valid value, a given gate is ready to compute its output when the phases of all “data” signals at its inputs are the same, different from the current phase of the output and the phase of the signal, if present, the same as the output phase. After the gate has performed its computation, the phase of its outputs become the common one of the data inputs and thus the signal toggles. 4.2 2-Phase, LEDR Protocol\n\nThis protocol is referred to as “level-encoded dual-rail”, or LEDR [13]. 4.2.1 Transmission of a Signal\n\nACK\n\nFigure 7: Transmission of a Signal and the acknowledge under the 2-phase-ledr protocol.

Under the 2-phase protocol a OR gate cannot express the “return to 0” condition. Therefore the wiring of Fig. 5 is modified according to Fig. 9.\n\nTwo MUX, controlled by a programming point, are added, which allow to replace the 6-in OR gate by the two other of the PLB. This way, each of and is now a rendez-vous of the outputs of 2 lut:\n\nEq. 8 shows the programming of lut\n\nand and Eq. 9 shows the programming of lut\n\nand.\n\n(8)\n\nWhen the conditions for a transition are fulfilled, and have the same value.

Otherwise and, the C-element within the memory element has different values on its inputs and is locked.\n\n(9)\n\nMutatis mutandis the same demonstrations shows the validity of.\n\n4.2.5 Conclusion on the 2-Phase, LEDR Protocol\n\nApart from the shaded area in Fig. 9 the 2-phase-ledr protocol needs the same resources as the 4-phase protocol.\n\nAs for security, all inputs to the gates have an equal load but the value of a signal\n\nis the value of one of. This is a potential security risk, which will have to be investigated as soon as the ICs have been delivered.\n\n4.3 2-Phase, Edge Protocol\n\nCompute Outputs Synchro Decode Detect &\n\nFigure 10: Global Structure of a 2-input 2-Phase-Edge gate.\n\nSignals under the 2-phase-edge protocol can take an arbitrary number of values. Binary signals are represented by 2 wires, ternary signals are represented by 3 wires, etc… However the complexity of the gates is quadratic in the number of wires per signal. Thus the use of this protocol is in practice limited to binary signals. The complexity of the gates is also quadratic in the number of inputs. Again this limits in practice the number of inputs to 2. In the sequel signals are binary and a signal is thus represented by 2 wires:\n\n.\n\nThe coding of the signals relies exclusively on toggling of wires. the instantaneous values of the wires is always irrelevant. This means that the current state of 4 wires has to be stored. Thus even for a 2-input gate all four lut of the PLB will have to be used.\n\n4.3.1 Structure of a Gate\n\nThe global structure of a 2-input gate under the 2-phase-edge protocol is depicted by Fig. 10. The operation of the gate is divided in three steps:\n\nDetection:\n\nwaits for an edge on and one on and toggles the corresponding,\n\nComputation:\n\ntoggles and\n\nSynchronization:\n\ntoggles and if and only if has toggled since the last data output.\n\nDetection: 2x2-decision wait\n\nC C C C\n\nFigure 11:.\n\nThe detection and the decoding of the input data is performed by the circuitry known as the “ 2x2-decision wait ” or, shorter, the “ ”. The circuitry, shown on Fig. 11, works as follows:\n\n1.\n\nassume an initial state such that, for each C-element, the inputs are equal, (as this is the initial state, with all wires set to 0, the recurrence can start),\n\n2.\n\nafter an input value has arrived on input port and an input value\n\non input port, and have toggled (double-thickness continuous lines)\n\n3.\n\nat this point:\n\n-   one input to\n\nhas toggled\n\nis unchanged,\n\n-   one input to\n\nhas toggled\n\nis unchanged,\n\n-   both inputs to\n\nhave toggled\n\ntoggles,\n\n4.\n\nthe new value of is sent to the next stage and to the appropriate XOR gates to cancel the unwanted toggling of and (double-thickness dashed lines),\n\n5.\n\nall four C-elements now have their inputs identical, which was the initial situation and\n\nhas toggled, indicating to the next stage that:\n\n•\n\nboth input ports and have received a new data,\n\n•\n\nthe data just arrived on was and\n\n•\n\nthe data just arrived on was.\n\nEach of the can be expressed as:\n\n(10)\n\nEach of the is a 5-term expression depending of:\n\n•\n\nthree feedback lines: (itself), and and\n\n•\n\ntwo input lines: and.\n\nThough the expression would fit in a, the feedback from one lut to the other would have to be routed through the general routing network, which has the following drawbacks:\n\n•\n\nit consumes routing resources,\n\n•\n\nthe timings of the feedbacks will be different between the feedback of a lut to itself (which is routed inside the PLB) and other, routed outside. This could be an attack point;\n\n•\n\nthe 2-input gate will always need 2 PLB: one for the and one for the computation itself.\n\nFigure 12: PLB with all feedbacks for the 2-phase-edge protocol.\n\nTherefore, these feedback have been added to the PLB, as shown on Fig. 12, which. As on preceding figures, the black triangles at the inputs of the lut are MUX controlled by programming points, which are denoted by “ ” in Eq. 11.\n\nWith these notations the equations of the 4 are:\n\n(11)\n\nM M\n\nFigure 13: Wiring used to implement the -decision-wait.\n\nTo implement the the input lines are assigned as in Eq. 12 and depicted by Fig. 13:\n\n(12)\n\nin which “ ” means “not connected” and Eq. 13 shows the interconnection of the feedbacks needed to implement the.\n\n(13)\n\nRemark 9\n\nis useless to compute and and is useless to compute\n\nand. The reason why these inputs are connected to the network but ignored in the programming of the lut is that and are connected twice from the network to the PLB and that the loads on this network must be identical for both variables.\n\nComputation & synchronization\n\nThe stage provides a decoded output: toggles if and data have arrived on inputs and respectively.\n\nComputing the outputs is then straightforward: each of and outputs is the XOR of the relevant. Let’s see some examples:\n\nGate\n\nAND\n\nNAND\n\nOR\n\nNOR\n\nXOR\n\nNXOR\n\nSynchronization\n\nC\n\nFigure 14: -decision-wait.\n\nThe synchronization is performed by a device called “ -decision-wait” (or, shorter:).

An attacker trying DPA, for instance, would have to exhibit the difference between the average consumption of both edges on wire ’1’ and the same average on wire ’0’.\n\n5 Programming the FPGA\n\nThe FPGA can be partially programmed: it is divided in square blocks which can be programmed separately from the other.\n\nC C C C C C Acknowledge signals\n\nFigure 16: FIFO memory for programming.\n\nThe programming chain is a set of asynchronous FIFO memories. An elementary stage of these FIFO is depicted by Fig. 16.\n\nAt RESET time, all C-elements are set to zero by a general RESET wire. Then the programming bits are fed to the FIFO, separated by values. The last stage of each FIFO is particular: the Acknowledge signal is controlled by an external pin. During the programming of the block, the Acknowledge signal is held low. This way the programming bits are stacked in the FIFO and the FPGA becomes functional.\n\nIf a partial reconfiguration is wanted, the chosen blocks are cleared by allowing the Acknowledge signal of their last stage to acknowledge the value in the last stage. Then the FIFO is activated again until all bits have gone thought it. At this point, the Acknowledge signal is blocked again and the FIFO is ready to receive a new set of configuration bits.\n\nDuring the configuration of the FPGA, all outputs of PLB are kept at 0 to avoid short-circuits. The PLB are programmed first, while all switchboxes are left in an insulation mode. Then the switchboxes are programmed to connect the newly reconfigured part to be connected to the still working part. It is the designer’s responsibility to ensure that the new part can create no conflict with the existing part.\n\n6\n\n## Conclusion\nWe have presented the programmable logic block of an asynchronous FPGA, which is oriented towards security rather than performance. In particular we have chosen not to implement one of the advantages of an asynchronous design, which usually allows to compute in average time: the early evaluation. This choice is deliberate as early evaluation is a security risk [40].\n\nThe FPGA can accommodate various sizes of data as well as various styles of asynchronous control, thus making it possible for the end user to design mixed styles of logic, depending on the applicative requirements. Incidentally, this FPGA is also a valuable prototype that allows to perform comparisons between styles of asynchronous protocols.\n\nA silicon is being manufactured and will be used for intensive testing. The different resistances of the various protocols against SCA will be evaluated. In particular the strict link under the 2-phase-ledr protocol between the value of a signal and the one of the\n\nwire will decide whether this protocol is suitable at all for a secure implementation."}]}

A central tool for achieving software protection is Cryptography. Cryptographic algorithms are most efficiently implemented in custom hardware than in software running on general purpose processors. Hardware implementations are of extreme importance in case of high performance, security against system intruders and busy systems, where a cryptographic task consumes too much time. Traditional ASIC solutions have the well-known drawback of reduced flexibility compared to software solutions. Since modern security protocols are increasingly becoming algorithm independent, a high degree of flexibility with respect to the cryptographic algorithms is desirable. The security degrees of all the techniques are based on the hardness of mathematical problems. Among them, Elliptic curve cryptography shows a promise to be an alternative of RSA. A promising solution which combines high flexibility with the speed and physical security of traditional hardware is the implementation of cryptographic algorithms on reconfigurable devices such as FPGAs. FPGAs are hardware devices whose function is not fixed and which can be programmed in-system [1]. It is essential for providing some requirements in Hardware and Software systems security. By using Symmetric Cryptography and its aspects, we can design some complex security systems with encryption algorithms. When we use a complex system like RFID tags, its security must be covered all of its elements. II. SYMMETRIC CRYPTOGRAPHY Symmetric key systems require both the sender and the recipient to have the same key. This key is used by the sender to encrypt the data, and again by the recipient to decrypt the data. Key exchange is clearly a problem. How do you securely send a key that will enable you to send other data securely? If a private key is intercepted or stolen, the adversary can act as either party and view all data and communications. You can think of the symmetric crypto system as akin to the Chubb type of door locks. You must be in possession of a key to both open and lock the door. Symmetric cryptography uses a single private key to both encrypt and decrypt data. Any party that has the key can use it to encrypt and decrypt data. They are also referred to as block ciphers. Symmetric cryptography algorithms are typically fast and are suitable for processing large streams of data. The disadvantage of symmetric cryptography is that it presumes two parties have agreed on a key and been able to exchange that key in a secure manner prior to communication. This is a significant challenge. Symmetric algorithms are usually mixed with public key algorithms to obtain a blend of security and speed.\n\nIII. SYMMETRIC CRYPTOGRAPHY AND ENCRYPTION MODULES ALGORITHMS IN RFID-BASED SYSTEMS Radio Frequency Identification (RFID) is an emerging technology. The main idea behind it is to attach a so called RFID tag to every object in a particular environment and give a digital identity to all these objects. An RFID tag is a small microchip, with an antenna, holding a unique ID and other information which can be sent over radio frequency. The information can be automatically read and registered by RFID readers. The data received by the RFID reader can be subsequently processed by a back-end database. Figure 1 gives a graphical overview of an RFID system. Figure 1: Overview of an RFID system The range of possible applications varies with the capability of the tag and is separated by different classes. Class 0 and Class 1 RFID tags are used as barcode replacement and are read-only or can be programmed only once in the field, respectively. Inventory maintenance which is used in the supply chain management can be automated using such tags. They are cheap (approximately 5 Cents) and can be used on item-level on nearly every product. This paper is focusing on more advanced tags (Class 2) which also have a rewritable memory and additional hardware resources but do not have an active power supply on the tag. The energy for operation is pulled from the electromagnetic field provided by the reader. In addition, the reader also provides the digital clock frequency for operation. Certain modulation methods are used for communication from the reader to the tag and vice versa. Such tags cost about 50 Cents and the available silicon area is about 10,000 gates. value products like pharmaceutical and branded goods can be protected against security vulnerabilities. In this paper, we demonstrate how the project ART (Authentication for long-range RFID systems) proposes to improve current RFID systems by providing secure authentication. The project is performed by four independent partners, two from industry and two academic partners. A major goal of the project is to enhance the functionality of current RFID tags with passive power supply. The basic functionality of RFID systems is to provide identification of individual objects by the replies the attached RFID tag sends to a request performed by a reader. The reader uses an attached database to link the received ID number to a specific object described in the database. The major drawback of those systems is that the communication scheme does not provide a method to prove the claimed identity. Since a typical tag answers its ID to any reader (without a possibility to check whether a reader is authorized to receive the information), and the replied ID is always the same, an attacker can easily forge the system by reading out the data of a tag and duplicating it to bogus tags. Closed RFID systems with common access of all readers to a central database, can check for illegal duplicates (bogus tags) within the database but this is not practical for many applications. Furthermore, it is impossible to distinguish the original tag from its illegal duplicates. Strong authentication mechanisms can solve uprising security problems in RFID systems and therefore give protected tags an added value. The three main security threats in RFID systems are forgery of tags, unwanted tracking of customers, and the unauthorized access to the tag’s memory. In this paper, we propose authentication protocols for RFID systems based on the ISO/IEC 9798-2 standard [2]. These protocols allow protecting high-value goods against adversary attackers. Additionally, we show that these protocols are feasible for nowadays restriction concerning data rates and compliance to existing standards as well as the requirements concerning chip area and power consumption. With authentication we mean a method to provide a proof for a claimed identity. This proof is based on a secret stored within the authenticating part of the system. As long as the secret information stays secret and the used protocol does not leak sensitive information, an attacker cannot forge a tag. A communication system providing authentication can reject access (to information, entry, etc.) to non authorized parties. To keep the authentication secure, it is necessary that an attacker does not gain information about the secret by listening passively to successful authentications. To fulfill this requirement for strong authentication, it is necessary to use cryptographically strong computations. A)Symmetric Authentication Authentication is the mechanism that one entity proves its identity to another entity. Strong authentication protocols, such as challenge-response protocols (standardized in ISO/IEC 9798) are widely used in practice today. In challenge-response protocols, one or several messages are exchanged between the party who wants to prove its identity (the claimant) and the party who wants to verify the identity (the verifier). This is called the protocol. In a typical scenario, the verifier challenges the claimant with an unpredictable value that is used no more than once (the nonce). The claimant is required to return a response that is depending on the nonce and on the stored secret. Using strong authentication for RFID systems leads to significant security enhancements. If readers are required to authenticate themselves to tags, attacks such as unwanted tracking and unauthorized memory access are rendered infeasible. If tags are required to authenticate themselves against readers forgery of tags is prevented. It is advantageous to use standardized protocols and algorithms because they have been rigorously cryptanalyzed and are widely used. systems based on standardized protocols and algorithms are more likely to be secure and interoperable with other well established infra-\n\nstructures. Standardized challenge-response protocols are defined upon symmetric-key and asymmetric-key cryptographic primitives. Using symmetric-key cryptography has the disadvantage that there is one secret key shared through all parties. If one key is compromised for any reason the whole systems gets insecure. However, strong asymmetrickey cryptography requires extremely costly arithmetic operations and is therefore out of question for RFID systems today. Strong symmetric-key cryptographic primitives include encryption primitives such as AES [3] which allow compact implementations [1]. In the following, a few authentication protocols based on challenge-response methods are explained. 1. Protocol Extension. The most important command is the anti-collision sequence which is a command every tag has to implement. Thereby, the reader sends an initial inventory command. All tags in the environment make a response which is the tag’s unique ID. If only one tag answers to the request the ID can be retrieved by the reader and all subsequent commands can be addressed using the ID which addresses one single tag. If two or more tags make an answer to a request a collision occurs. This can be detected at the reader. The reader then uses a modified inventory request where it adds a part of the tag’s ID to the request. Only tags which have this part of the ID are allowed to answer. Once the ID of one tag is identified, the reader sends a “stay quiet” command to the tag with the identified ID. This method is used as long as there are no more collisions and all tags within the environment are identified. Adding an authentication command to the ISO 18000 standard works by using a custom command which can be defined. The challenge-response protocol fits ideally to the overall request-response protocol. When authenticating a tag, the reader sends a challenge within the request and the tag answers according to the presented authentication protocol. 2. Interleaved Authentication Protocol. The authentication protocol mentioned above only works when the result of the cryptographic primitive is available within the time defined for the tag’s response. As this time is very short a modification of this authentication scheme was proposed where the calculation time for the algorithm is of minor importance. For this purpose, authentication is split into two parts. The first part is the Authentication Request (AR), which tells the tag to encrypt the challenge and does not expect any response. The second part is the Response Request (RR), which collects the authentication response, when the result is available. For one tag, the timing overhead is large, but with more than one tag, the reader can use the idle time (during the tag is busy calculating) to send authentication requests (or other requests) to other tags [4]. 3.Cryptographic Hardware Module. Computation of the cryptographic algorithm AES (Advanced Encryption Standard) is computationally very complex compared to other tasks of tags. The implementation of the AES that fulfils the requirements concerning low power consumption and low die size is far away from being trivial. The current consumption of additional hardware components on an RFID tag must not exceed 10µA to avoid reduction of the operating range [5]. By using these algorithms, we can design a complex encryption systems that can be influenced on software and hardware modules in RFID-based systems. Our main strategy in defining a security base for complex systems is with following steps:  Software-based Security(SbS)  Hardware-based Security(HbS)  Complexity-based Security(CbS) This methodology is our main focus on “Parallel Cryptography” which has been designed in three separate steps and finally added to an unique cycle that its planning is in Symmetric Cryptographic algorithms as showed in figure 2. Figure 2: Complex Symmetric Cryptography diagram IV. BENEFITS OF PARALLEL CRYPTOGRAPHY USING When a complex system uses Parallel Security System (PSS), probability of mistakes in description has been decreased, because of designing a complex system with three main security base that can support security of software, hardware and a combination security by Symmetric Cryptography and parallel security. Figure 3 shows that how a Parallel Security System can cover all of cryptographic security base in a complex design. SbS HbS CbS\n\nFigure 3. Parallel Security System in a complex design V.\n\n## CONCLUSION\nAt this paper, we show that the most application Symmetric-based security systems in complex designing is Parallel Security System (PSS). When we use a Parallel Security System, we can support all of software and hardware layers in a complex design and by using this algorithm coverage of all subsystems can be provided. Our main strategy discussion in a sample complex system such as RFID tags can make a secure and safe space for using these kinds of systems. Three steps PSS in complex designing can make a cover layer between processing all of procedures."}]}

KDD Cup 1999 Dataset\nThe KDD cup 1999 dataset was used in the 3rd International Knowledge Discovery and Data Mining Tools Competition for building a network intrusion detector, a predictive model capable of distinguishing between intrusions and normal connections [37]. In 1998, DARPA intrusion detection evaluation program, a simulated environment was set up to acquire raw TCP/IP dump data for a local-area network (LAN) by the MIT Lincoln Lab to compare the performance of various intrusion detection methods. It was operated like a real environment, but being blasted with multiple intrusion attacks and received much attention in the research community of adaptive intrusion detection. The KDD99 dataset contest uses a version of DARPA98 dataset. In KDD99 dataset, each example represents attribute values of a class in the network data flow, and each class is labelled either normal or attack. The classes in KDD99 dataset can be categorized into five main classes (one normal class and four main intrusion classes: probe, DOS, U2R, and R2L). 1) Normal connections are generated by simulated daily user behaviour such as downloading files, visiting web pages. 2) Denial of Service (DoS) attack causes the computing power or memory of a victim machine too busy or too full to handle legitimate requests. DoS attacks are classified based on the services that an attacker renders unavailable to legitimate users like apache2, land, mail bomb, back, etc. 3) Remote to User (R2L) is an attack that a remote user gains access of a local user/account by sending packets to a machine over a network communication, which include send-mail, and Xlock. 4) User to Root (U2R) is an attack that an intruder begins with the access of a normal user account and then becomes a root-user by exploiting various vulnerabilities of the system. Most common exploits of U2R attacks are regular buffer-overflows, load-module, Fd-format, and Ffb-config.\n\n20\n\n5) Probing (Probe) is an attack that scans a network to gather information or find known vulnerabilities. An intruder with a map of machines and services that are available on a network can use the information to look for exploits. In KDD99 dataset these four attacks (DoS, U2R, R2L, and probe) are divided into 22 different attacks that tabulated in Table 2. Table 2.

The first group of attributes is the basic features of network connection, which include the duration, prototype, service, number of bytes from source IP addresses or from destination IP addresses, and some flags in TCP connections. The second group of attributes in KDD99 is composed of the content features of network connections and the third group is composed of the statistical features that are computed either by a time window or a window of certain kind of connections.

In this paper we have concentrated on the development of the performance of naïve Bayesian classifier and ID3 algorithm. It has been successfully tested that this hybrid algorithm minimized false positives, as well as maximize balance detection rates on the 5 classes of KDD99 benchmark dataset. The attacks of KDD99 dataset detected with 99% accuracy using proposed algorithm. The future work focus on improving the false positives of remote to user (R2L) attack and apply this detection model into real world IDS.\n\n## 4.1. Proposed Learning Algorithm\nGiven a training data D = {t1,…,tn} where ti = {ti1,…,tih} and the training data D contains the following attributes {A1, A2,…,An} and each attribute Ai contains the following attribute values {Ai1, Ai2,…,Aih}. The attribute values can be discrete or continuous. Also the training data D contains a set of classes C = {C1, C2,…,Cm}. Each example in the training data D has a particular class Cj. The algorithm first searches for the multiple copies of the same example in the training data D, if found then keeps only one unique example in the training data D (suppose all attribute values of two examples are equal then the examples are similar). Then the algorithm discreties the continuous attributes in the training data D by finding each adjacent pair of continuous attribute values that are not classified into the same class value for that continuous attribute. Next the algorithm calculates the prior P(Cj) and conditional P(Aij|Cj) probabilities in the training data D. The prior probability P(Cj) for each class is estimated by counting how often each class occurs in the training data D. For each attribute Ai the number of occurrences of each attribute value Aij can be counted to determine P(Ai). Similarly, the conditional probability P(Aij|Cj) for each attribute values Aij can be estimated by counting how often each attribute value occurs in the class in the training data D. Then the algorithm classifies all the examples in the training data D with these prior P(Cj) and conditional P(Aij|Cj) probabilities. For classifying the examples, the prior and conditional probabilities are used to make the prediction. This is done by combining the effects of the different attribute values from that example. Suppose the example ei has independent attribute values {Ai1, Ai2,…,Aip}, we know P(Aik | Cj), for each class Cj and attribute Aik. We then estimate P(ei | Cj) by P(ei | Cj) = P(Cj) ∏k=1→p P(Aij | Cj)\n\n(7) To classify the example, the algorithm estimates the likelihood that ei is in each class. The probability that ei is in a class is the product of the conditional probabilities for each attribute value with prior probability for that class. The posterior probability P(Cj | ei) is then found for each class and the example classifies with the highest posterior probability for that example.\n\n18\n\nAfter classifying all the training examples, the class value for each example in training data D updates with Maximum Likelihood (ML) of posterior probability P(Cj|ei). Cj = Ci→ PML(Cj|ei).\n\n(8) Then again the algorithm calculates the prior P(Cj) and conditional P(Aij|Cj) probabilities using updated class values in the training data D, and again classifies all the examples of training data using these probabilities. If any of the training example is misclassified then the algorithm calculates the information gain for each attributes {A1, A2,…,An} in the training data D. Info(D) = ∑ =       − m j j j D D C freq D D C freq 1 2 | |), ( log | |), (\n\n(9) Info(T) =) ( inf | | | | 1 i n i i T o T T ∑ =\n\n(10) Information Gain (Ai) = Info(D)-Info(T)\n\n(11) And chooses one of the best attributes Ai among the attributes {A1, A2,…,An} from the training data D with highest information gain value, Then split the training data D into sub-datasets {D1, D2,…,Dn} depending on the chosen attribute values of Ai. After the algorithm estimates the prior and conditional probabilities for each sub-dataset Di = {D1, D2,…,Dn} and classifies the examples of each sub-dataset Di using their respective probabilities. If any example of any subdataset Di is misclassified then the algorithm calculates the information gain of attributes for that sub-dataset Di, and chooses the best attribute Ai with maximum information gain value from sub-dataset Di, and split the sub-dataset Di into sub-sub-datasets Dij. Then again calculates the prior and conditional probabilities for each sub-sub-dataset Dij, and also classifies the examples of sub-sub-datasets using their respective probabilities. The algorithm will continue this process until all the examples of sub/sub-sub-datasets are correctly classified. When the algorithm correctly classifies all the examples then the prior and conditional probabilities for each datasets are preserved for future classification of unseen examples. The main procedure of proposed algorithm is described as follows. Algorithm Input: Training Data, D Output: Adaptive Intrusion Detection Model, AIDM Procedure: Step 1: Search the multiple copies of same example in D, if found then keeps only one unique example in D. Step 2: For each continuous attributes in D find the each adjacent pair of continuous attribute values that are not classified into the same class value for that continuous attribute Step 3: Calculate the prior probabilities P(Cj) and conditional probabilities P(Aij|Cj) in D. Step 4: Classify all the training examples using these prior and conditional probabilities, P(ei | Cj) = P(Cj) ∏k=1→p P(Aij | Cj). Step 5: Update the class value for each example in D with Maximum Likelihood (ML) of posterior probability, P(Cj|ei); Cj = Ci→ PML(Cj|ei). Step 6: Recalculate the prior P(Cj) and conditional P(Aij|Cj) probabilities using updated class values in D.\n\n19\n\nStep 7: Again classify all training examples in D using updated probability values. Step 8: If any training examples in D is misclassified then calculate the information gain for each attributes Ai = {A1, A2,…,An} in D using equation (11). Step 9: Choose the best attribute Ai from D with the maximum information gain value. Step 10: Split dataset D into sub-datasets {D1, D2,…,Dn} depending on the attribute values of Ai.

Then again calculate the probabilities for each sub-sub-dataset Dij. Also classify the examples in sub-subdatasets using their respective probabilities. Step 14: Continue this process until all the examples are correctly classified.

Networking Overview\nIn the networks, TCP/IP is widely used for network communications, which are composed of four layers: application layer, transport layer, network layer, and hardware layer that work together [19]. When data transfers across the networks, the data passes from the highest layer through intermediate layers to the lowest layer. The lowest layer sends the accumulated data to its destination through the physical network. Application layer sends and receives data for particular applications, such as DNS, HTTP, FTP, SMTP, and SNMP. It enables applications to transfer data between server and client, and passes application data to the transport layer. Transport layer is responsible for packaging data using TCP (Transmission control protocol) and UDP (user datagram protocol) so that it can be transmitted between hosts. Each TCP or UDP packet has a source port and a destination port number. Network layer or internet protocol (IP) layer is in charge of handling the addressing and routing of data received from the transport layer. After the network layer has encapsulated the transport layer data, the resulting logical units are referred to as packets. Each packet contains a header, which is composed of various fields. Commonly used network layer protocols are IPv4, IPv6, ICMP (internet control message protocol), and IGMP (internet group management protocol). It is also responsible for providing error and status information involving the addressing and routing of data. Hardware layer or data link layer tackles communications on the physical network components including cables, routers, switches, and network interface cards (NIC). The best known hardware layer protocol is Ethernet. Ethernet relies on the concept of a media access control (MAC) address, which is a unique six-byte value (such as 00-02-B4-DA-92-2C) permanently assigned to a particular NIC.\n\n14\n\n## 2.2. Intrusion Detection Overview\nIntrusion detection is the process of monitoring and analyzing the events in computer systems or networks to discover the signals of possible incidents, which attempt to compromise the confidentiality, integrity, and availability of computer resources. In general, IDS use misusebased and anomaly-based detection model for detecting intrusions. Misuse-based IDS are very effective for detecting known attacks but largely ineffective for detecting new attacks whose pattern has not stored in the database yet. It performs pattern matching to match an attack pattern corresponding to known attack patterns in the database. Anomaly-based IDS identify new attacks by analyzing anomalous behavior from normal behaviors. It has a relatively high detection rate for new attack, but produces many false positives. It uses profiles that are developed by monitoring the characteristics of typical activities over a period of time and then compares the characteristics of current activity to thresholds related to the profile. A networkbased IDS (NIDS) monitor and analyze network traffics, and use multiple sensors for detecting intrusions from internal and external networks [20]-[22]. IDS analyze the information gathered by the sensors, and return a synthesis of the input of the sensors to system administrator or intrusion prevention system. System administrator carries out the prescriptions controlled by the IDS. Today, data mining has become an indispensable tool for analyzing the input of the sensors in IDS. Fig. 1 shows a scenario of IDS to protect server machine from internal and external network.\n\nFigure 1. A typical motivating scenario of intrusion detection. Ideally, IDS should have an attack detection rate (DR) of 100% along with false positive (FP) of 0%. Nevertheless, in practice this is really hard to achieve. The most important parameters involved in the performance estimation of IDS are shown in Table 1. Table 1. Parameters for performance estimation of IDS. Parameters Definition True Positive (TP) or Detection Rate (DR) Attack occur and alarm raised False Positive (FP) No attack but alarm raised True Negative (TN) No attack and no alarm False Negative (FN) Attack occur but no alarm\n\n15\n\nThe metrics such as precision, recall, overall, and false alarm have been used to measure the performance of the data mining algorithm on the minority class [23]-[26]. From Table 1, precision, recall, and overall may be defined as follows.

Related Work\nIn 1980, the concept of intrusion detection began with Anderson’s seminal paper [40]; he introduced a threat classification model that develops a security monitoring surveillance system based on detecting anomalies in user behavior. In 1986, Dr. Denning proposed several models for commercial IDS development based on statistics, Markov chains, time-series, etc [41]. In the early 1980’s, Stanford Research Institute (SRI) developed an Intrusion Detection Expert System (IDES) that monitors user behavior and detects suspicious events [42]. In 1988, a statistical anomaly-based IDS was proposed by Haystack [43], which used both user and group-based anomaly detection strategies. In 1996, Forrest et al. proposed an analogy between the human immune system and intrusion detection that involved analyzing a program’s system call sequences to build a normal profile [44]. In 2000, Valdes et al. [45] developed an anomaly based IDS that employed naïve Bayesian network to perform intrusion detecting on traffic bursts. In 2003, Kruegel et al. [46] proposed a multisensory fusion approach using Bayesian classifier for classification and suppression of false alarms that the outputs of different IDS sensors were aggregated to produce single alarm. In the same year, Shyu et al. [47] proposed an anomaly based intrusion detection scheme using principal components analysis (PCA), where PCA was applied to reduce the dimensionality of the audit data and arrive at a classifier that is a function of the principal components. In 2003, Yeung et al. [2] proposed an anomaly based intrusion detection using hidden Markov models that computes the sample likelihood of an observed sequence using the forward or backward algorithm for identifying anomalous. Lee et al. [48] proposed classification based anomaly detection using inductive rules to characterize sequences occurring in normal data. In 2000, Dickerson at al. [49] developed the Fuzzy Intrusion Recognition Engine (FIRE) using fuzzy logic that process the network data and generate fuzzy sets for every observed feature and then the fuzzy sets are used to detect network attacks. In 2003, Ramadas et al. [50] presented the anomalous network traffic detection with self organizing maps using DNS and HTTP services that the neurons are trained with normal network traffic then real time network data is fed to the trained neurons, if the distance of the incoming network traffic is more than a preset threshold then it raises an alarm.\n\n16\n\n## 3.1. Handling Noise in Dataset\nNoise in the dataset is considered to be one of the most challenging issues in data mining. This is because the performance of the learning algorithms depends on the quality of dataset. The main idea of dealing with noisy data at the learning time is to avoid over-fitting the dataset. Noise handling can be carried out at different stages of rule induction and interpretation. The followings exhibit some typical noises being existed in the dataset. 1) Missing attribute values: The simplest way for handling missing or unknown attribute value is to replace the missing attribute value with the most frequent attribute value in the dataset. Whereas, the most sophisticated way is to calculate the probability for attribute values and assign the probability value rather than the guessed value to each missing attribute value. 2) Contradictory examples: The same examples appear more than once in the dataset with different class labels. Contradictory examples confuse the learning algorithms, so these examples should be avoided or labeled correctly before learning. 3) Redundant examples: There often exist multiple copies of the same example in the dataset. Redundant examples are not a problem if they do not form contradictions, but this redundancy can change the decision trees produced by ID3 algorithm. For data mining, it’s better to remove redundancy by keeping only a unique example in the dataset. By doing so, it not only saves the space of storage in dataset but also speeds significantly up the learning process. 4) Incomplete attribute problem: When the essential attributes of a problem are not used to describe in the dataset. Suppose to distinguish men from women based on the descriptions of a large group of people in terms of gender, height, weight, qualifications, and so on. The right attribute for men is “gender = male” and women is “gender = female”. If we cannot catch the right attribute, then the classification model will be more complex and less accurate. 5) Misclassified examples: The examples in the dataset ware labeled with a wrong classification.\n\n## 3.2. Dealing with Continuous Attribute\nThe goal of dealing with continuous attributes is to discretized the continuous attribute containing continuous values (i.e., real numbers or integers) into a number of intervals. The discretized intervals can be treated in a similar way to nominal values during learning and classification. It is very important for discretization of continuous attribute to find the right places to set up interval borders. The simplest technique is to place the interval borders of continuous attribute values between each adjacent pair of attribute values that are not classified into the same class. Suppose the pair of adjacent values on attribute Ai are Ai1 and Ai2, “A = (Ai1+Ai2)/2” can be taken as an interval border. The information gain technique adopted in ID3 algorithm is another very efficient technique to find the most informative border to split the values of the continuous attribute. The maximum information gain is always considered for a cut point (the midpoint) between the values taken by two attribute values of different classes. Each value of the formula “A = (Ai +Ai+1)/2” where i = 1,…,n-1 is a possible cut point, if Ai and Ai+1 have been taken by different class values in the dataset. The purpose of employing information gain is to check each of the possible cut points and find the best split point. In C4.5 algorithm, each of the possible cut points is not the midpoint between the two nearest values,\n\n17\n\nrather than the greatest value in the entire dataset that does not exceed the midpoint. The naïve Bayesian classifier also uses for discretization of continuous attribute values by constructing a probability curve for each class in the dataset. When the curves for every class have been constructed, interval borders are placed on each of those points where the leading curves are different from its two sides. A few other methods such as equal distance division, grouping, knearest neighbors, and fuzzy borders are also applied to the continuous attributes for discretization.\n\n## 3.3. Input Attribute Selection from Dataset\nEffective input attribute selection from dataset before learning is very important, because irrelevant and redundant attributes of dataset may lead to complex classification model as well as reduce the classification accuracy [29]-[36]. In complex classification domains, input attributes of dataset may contain false correlations, which hamper the classification process. Some attributes in the dataset may be redundant, because the information they add is contained in other attributes. Also, some extra attributes can increase the computational time, and can have impact on the classification accuracy. Input attributes selection using data mining involves the selection of a subset of attributes d from a total of D original attributes of dataset, based on a given optimization principle that improves the performance of classifier. Finding a useful attribute subset is a form of search. Ideally, attribute selection methods search through the subsets of attributes, and try to find the best ones among the completing 2N candidate subsets according to some evaluation function."}]}

To be effective in carrying out their functions, the IDSs need to be accurate, adaptive, and extensible. Given these stringent requirements and the high level of vulnerabilities of the current days’ networks, the design of an IDS has become a very challenging task. Although, an extensive research has been done on intrusion detection in a distributed environment, distributed IDSs suffer from a number of drawbacks e.g., high rates of false positives, low detection efficiency etc. In this paper, the design of a distributed IDS is proposed that consists of a group of autonomous and cooperating agents. In addition to its ability to detect attacks, the system is capable of identifying and isolating compromised nodes in the network thereby introducing fault-tolerance in its operations. The experiments conducted on the system have shown that it has high detection efficiency and low false positives compared to some of the currently existing systems.\n\n## 1. Introduction\nThere have been two different approaches for securing networks and host computers from malicious attackers: i) intrusion prevention mechanisms that include cryptographic techniques to safeguard sensitive information from unauthorized access, ii) intrusion detection mechanisms that recognize an ongoing attack on a system and respond appropriately to thwart such intrusive attempts. An intrusion detection system (IDS) is a security mechanism that can monitor and detect intrusions to the computer systems in real time. An IDS can be either host-based or network-based or a combination of both. The conventional approach to intrusion detection involving a central unit to monitor an entire system has several disadvantages [1]. To circumvent the demerits of a centralized IDS, the research in the field of intrusion detection over the last decade has been heading towards a distributed framework. In these systems, the local intrusion detection components look for local intrusions and pass the results of their analyses to the upper levels in the hierarchy. The components at the upper levels analyze the refined data from multiple lower level components and seek to establish a global view of the system state. In this paper, the scheme of a distributed IDS is presented. This is an extension of our earlier work presented in [2]. In the proposed IDS, the knowledge about attack scenarios is introduced into a large number of agents in the form of a Bayesian network so that each agent is required to monitor only a relatively few aspects of the local network. However, the agents share their beliefs, and through timely coordination of the agents, the system is able to detect complex distributed attacks. For distributed inference, the concept of multiply sectioned Bayesian networks (MSBN) [3] is used in domain knowledge representation. To reduce network congestion and message overhead, the agents are grouped into subdomains. The communications among the agents are mostly confined in the subdomains. The main contributions of the paper are as follows. It presents a scheme for intrusion detection that provides: (i) efficient detection of intrusive activities by local monitoring and sharing of individual belief estimates of the agents for a collaborative detection, (ii) fault-tolerance by prompt identification and isolation of compromised hosts in the network through a distributed trust framework, and (iii) better detection efficiency and reduced false positives while providing enhanced robustness and fault-tolerance compared with the existing intrusion detection schemes. The organization of the paper is as follows. Section 2 describes the architecture of the system, agents and their communication framework. Section 3 discusses Bayesian intrusion detection framework used in the proposed system. Section 4 presents a distributed trust framework that enhances the fault-tolerance of the security mechanism. Section 5 presents the experimental results. Section 6 concludes the paper while identifying some future scope of work.\n\n## 2. Architecture of the system and agents\nIn this section, the architecture of the system and its constituent agents are described. The proposed system consists of a large number of agents that collect data, analyze, and make appropriate inference. The agents use an inference process that utilizes a Bayesian network of data. The agents are grouped into several subdomains. The agents in the same subdomain communicate actively and frequently. Communication between agents belonging to adjacent subdomains happens infrequently. The agents have knowledge about a Bayesian network model of the structures of wellknown attack types as well as normal usage pattern, which is constructed offline from data repositories containing system logs from ongoing attacks. The global Bayesian network is partitioned into multiple subnets based on the spatial locations of the agents. Bayesian network approach allows for combining anomaly detection and signature recognition. For this purpose, one Bayesian network is generated whose nodes classify known attack types and normal behavior. Using this network, the agents can detect normal behavior and known attacks. If the probabilities associated with none of the target nodes cross the threshold, the system detects an anomalous behavior. Every host in the system has one special agent, called the distributed trust manager (DTM). It uses the Byzantine Agreement Protocol among the peers and identifies any compromised host in the system. This distributed trust mechanism makes the proposed system robust and fault-tolerant.\n\n## 4.2. The Byzantine agreement protocol\nLamport et al. described the Byzantine Generals Problem in [7]. The problem is as follows: Imagine that several divisions of a Byzantine army are camped outside an enemy city, each division commanded by its own general. The generals can communicate with each other only by messengers. After observing the enemy, they must arrive at a common plan of action. However, some of the generals may be traitors, and try to prevent the loyal generals from reaching an agreement. The generals must have an algorithm to guarantee that all loyal generals decide upon the same plan of action. The loyal generals will all do what the algorithm asks them to do; however, the traitors may do anything they wish. The BAP is essentially an algorithm designed to achieve consensus among a set of processes in a distributed system. These processes can arrive at a consensus if they all agree on some allowed values called the outcome (if they could agree on any value the solution would be trivial: always agree on ‘0’). Thus arriving at a consensus involves two actions: first specify a value, and the read the outcome of execution of the processes involved. The consensus algorithm terminates when all non-faulty processes come to know the outcome. If we consider the generals in BAP as the hosts in a distributed system, and the consensus as the requirement of agreement among the hosts as which hosts are safe (i.e. not compromised), then the problem of identifying compromised host(s) in a distributed can be described more formally as follows. Consider a distributed system consisting of a large number of hosts, with each host having a group of agent. The agents cooperate to detect malicious intrusive attempts or actual intrusions into the system. Each host has a special agent - distributed trust manager (DTM), which continuously sends messages to its peers. The messages sent by the DTM are of two types: (i) Message A1: the host is safe with a value ‘0’, (ii) Message A2: the host is compromised with a value, ‘1’. Lamport et al. proposed a signed message algorithm (SMA) for solution of the Byzantine Generals Problem which requires O(n2) messages for n hosts. It works effectively if there are at most n - 2 traitors (i.e. compromised hosts). However for SMA to work correctly, some conditions need to be satisfied: (i) each message is delivered correctly, (ii) the receiver of a message knows its sender, (iii) the absence of a message in the buffer of a host can be detected, (iv) the signature of a safe (i.e. not compromised) host cannot be forged, and (v) any host can verify the authenticity of its general’s signature. With cryptographic mechanisms in place, the proposed system guarantees that all the above conditions are satisfied and hence SMA will work well. In the SMA, one of the hosts acts as the leader and sends an order to the other hosts. Whenever a host receives a message, it takes the order and puts it in its list of the orders received. Then the receiver signs the message with its own signature and forwards it to all the hosts whose signature is not on the order. If a host receives a message with an order that is already in his\n\nlist, it ignores the message. When no more messages are left to be received, all the hosts choose an order from the list of orders they have received using this method. If only one order has been received, that order is chosen. Because any order that reaches a safe host will be forwarded to all other hosts who have not seen the order, all the safe hosts will have the same set of orders to choose from, and thus choose the same order to obey.\n\n## 4.3. Distributed trust manager\nDTM forms and maintains trust domains. A trust domain is a set of hosts that share a charter and a security policy and behave consistently in accordance with that policy. The hosts in a trust domain ensure that no compromised host can join the trust domain. To understand the functions of DTM, we assume that at the beginning of a trust domain formation, all the hosts are safe. Any compromised host in the trust domain is identified by running n instances (n is the number of hosts in the trust domain) of SMA in parallel, assuming that the majority of the hosts in the trust domain are not compromised. If the leader of the SMA is not compromised, then after running the algorithm in parallel, all the hosts that are not compromised will know that the leader is not compromised. However, if the leader happens to be compromised, then one of the following possible cases may happen: (i) The leader sends ‘0’ to all the safe hosts. In this case, all the safe hosts will assume the leader host to be compromised or dead. (ii) The leader sends ‘1’ to only some of the safe hosts. In this case, those safe hosts that have received ‘1’ from the leader are able to detect that there is a compromised host in the system. These hosts, then, send messages to other hosts informing about the suspected compromised host. On further investigation based on additional message communication, the actual status (compromised or otherwise) of the suspected node would be understood. (iii) The leader sends ‘1’ to all safe hosts. The safe hosts can now realize that the message is wrong, and the leader itself is compromised if it contradicts the majority. If the message does not contradict the majority, it is not possible to conclude about the status of the leader unless it sends a different message to at least one compromised host, which in turn forwards the message to a safe host. In the latter case, the leader host is compromised and is isolated. (iv) The leader sends two (or more) different messages to some of the safe hosts. The all the safe hosts together find contradictory instructions, and understand that the leader is compromised. In this way, DTM can detect compromised nodes in the system in all possible cases."}]}

Experiments and Results\nA proof-of-concept prototype for the proposed IDS has been built using Java and the JADE [4] environment. JADE is a middleware for enabling faster development of multi-agent distributed applications based on the peer-to-peer communication architecture. In the prototype IDS, each agent is endowed with three behavioral capabilities: filtering, interaction, and deliberation. The filtering behavior of an agent enables it to filter security events from the observations it makes. The interaction behavior manages the interaction of the agent with its peers and defines the way the messages are received and enqueued. The deliberation behavior allows an agent to represent its beliefs, goals, intentions, and knowledge in a semantic format. When an agent receives a detection goal, it updates a set of event classes to filter. When an event occurs, it is filtered by the filtering module and sent to the deliberation module. The deliberation module updates the agent’s beliefs, and checks whether the belief matches with an attack signature. If it matches, a detection goal is reached and a list of intentions is sent to the interaction module for execution. Experiments have been conducted to test the performance of the proposed IDS. The KDD Cup 1999 intrusion detection contest data [8] has been used in the experiments. The original data contains 744 MB of information with 4.94 million records. The dataset has 41 attributes for each connection record plus one connection record specifying one of 24 different types of attacks or normal condition. Thus, effectively each record is given a class label that specifies the category of attack to which the record belongs. All the attacks are grouped into 4 major categories: (i) denial of service (DoS), (ii) remote to local (R2L), (iii) user to root (U2R), and (iv) probe. A dataset of 15000 records is constructed by randomly selecting records from the original database, such that the number of data instances selected from each class was proportional to their frequencies in the original database. An additional class called the normal class is also constructed. The attack knowledge base is distributed among the agents, and a Bayesian network power constructor (BNPC) [9] is used to generate a Bayesian network from these sampled records. This Bayesian network is sectioned into multiple subnets utilizing the rules for sound partitioning in MSBN [3]. Finally, the LJF method is used for intrusion detection. The prototype is tested in a network of 50 workstations. Each workstation has Pentium 4 processor, 3GHz clock speed, 1 GB RAM, and Linux operating system. The interconnecting medium is Ethernet with 100 mbps capacity. Using the Ethereal\n\nnetwork sniffer, memory, CPU cycle and bandwidth consumption due to the agents are evaluated. From Table 1, it is evident that the average memory and the CPU usage on a workstation due to the IDS are marginal and the overhead decreases with increase in number of users. The maximum CPU usage by the agents is found to be 8.76% with the average being 5.34%. During the period when the agents were active, only 15% increase in number of packets is found in the network. The average bandwidth consumed by the agents never exceeded 5%. Table 1.

The detection efficiency of the proposed IDS is also compared with the scheme proposed by Li et al in [10]. From Table 2, it is evident that except for the ‘normal’ scenario, the detection rate of the proposed IDS is better than that of Li et al.’s scheme [10]. Table 2.

However, like most of the existing IDS schemes, the proposed scheme has a low detection rate for R2L attacks. Although, the detection rate for these attacks is much higher compared to Li et al.’s scheme, it is far from satisfactory. Since R2L attacks are essentially different from the other types of attacks, there is a need for a different approach for detection logic. The DTM scheme is mostly responsible for the higher detection rates in DoS and probe attacks. The false positive rates are also found to be fairly low for all categories of attacks.\n\n## 6. Conclusion\nThis paper has presented the framework of a distributed IDS that consists of a group of agents cooperating with each other to carry out the task of intrusion detection. Using distributed computation and message passing, the agents detect both signaturebased attacks and anomalous activities in real-time. Apart from its ability to make distributed inference, the proposed IDS can also identify compromised nodes in the system with the help of Byzantine Agreement Protocol. The experiments show that the performance of the IDS is better than some of the currently existing systems. Development of a new detection logic for R2L type of attacks constitutes a future plan of work.\n\n## 2.1. Agent architecture\nFigure 1 depicts the architecture of an agent. Each agent consists of six modules. The functionalities of each of these modules are briefly described below.\n\nFigure 1: Architecture of an agent in a node Perception module is responsible for collection of audit or network data of the subdomain to which the agent belongs. Deliberation module is responsible for analyzing the data collected by the perception module. It enables an agent to reason and extrapolate by relying on built-in knowledge and allows the agent to update its belief in the subnet it is monitoring. Communication module allows an agent to communicate its belief, decisions, and knowledge to its peer agents in the same subdomain, and possibly, to other subdomains also. Action module takes appropriate actions when an intrusion is detected. When an agent recognizes that a monitored host has exceeded the threshold of one known attack, it triggers an alert and communicates it to the system administrator. The agents can also trigger an alert indicating an anomalous situation, when the activated target node does not belong to those representing normal behavior or any of the known attack types. The system administrator can either confirm the attack (or take necessary steps to handle it), or reject the alert if it is found to be a false alarm. Knowledgebase update module updates the attack signature database if the system administrator confirms an anomaly alert. The Bayesian network is modified to accommodate this new attack in the knowledge base. Supervisory module is the central module that coordinates the tasks and interactions among the other modules.\n\n## 2.2. Communication system of agents\nAs shown in Figure 2, three types of agents are deployed in the proposed system. The system monitoring agents collect, transform, and distribute intrusion specific data when requested and evoke information collection procedures. The intrusion monitoring agents subscribe to beliefs published by the\n\n## system\nmonitoring agents and other intrusion monitoring agents. Each intrusion monitoring agent has the knowledge of a local Bayesian network of attacks. These agents update their knowledge on receipt of information from other agents. For each registered agent, a registry is maintained for the variables it monitors. The agents use the registry to find the names and locations of agents, which may have data that they are interested in. The messages are in XML format and may be of different types e.g.: (i) registration of agents with registry agents, (ii) request to registry agents for locations of other agents, (iii) search of agent queries, iv) belief subscription requests, v) belief updates. Figure 3 shows two different types of communication among the agents. Various mechanisms exist for these communications [4]. In the proposed mechanism, the shared memory architecture is used for agent communication since it allows large\n\nefficient communication among agents over the\n\nnetwork, an agent management system (AMS) is used. The capabilities provided by the java agent development environment (JADE) [4] framework has been utilized to build an AMS.\n\nFigure 2: Major components of the system\n\nFigure 3: Agent communication architecture\n\nFor security, public key infrastructure (PKI) is used to provide two-way authentication of the agents and the messages. The messages are encrypted using symmetric key cryptography.\n\n## 3. Bayesian Intrusion Detection\nThis section describes how the concepts of Bayesian networks and MSBNs are applied in the proposed IDS. As mentioned in Section 3, the knowledgebase of the attacks are distributed in the agents in the form of a Bayesian network. A Bayesian network is a directed acyclic graph (DAG) in which the nodes represent the variables, and each directed edges represents a dependency between the corresponding variables. The effect of the parents of a node on a node is represented by conditional probabilities of that variable given values of its parent nodes in the form of a conditional probability table (CPT). There are several reasons for using Bayesian network in the proposed system. First, a Bayesian network can handle incomplete information, which is suitable for the agents that have limited local view of the network and may receive only partial information about a possible attack. Secondly, a Bayesian network can represent causal relationships among variables, which can help an intrusion detection model to combine a priori knowledge and observed data to take a decision. Finally, a Bayesian network allows updating of the beliefs and thus can be used to recognize novel attack signatures. In the proposed system, a Bayesian network is first constructed from a database of known attacks, which is then partitioned into several subtrees following the principle of MSBNs [3], and distributed among the agents. This process is explained in the following subsection.\n\n## 3.1. Inference with MSBNs\nAn MSBN consists of a set of interrelated Bayesian subnets each of which encodes an agent’s knowledge of a subdomain. In such a framework, probabilistic inference can be performed in a distributed fashion. Multiagent inferences in MSBNs are usually done using message passing in junction trees (JTs) [3]. The linked junction forest (LJF) method compiles each subnet of a multiply connected network into a JT by clustering the triangulated moral graph of the underlying undirected graph. The algorithm performs message propagation over the JT. Message passing among agents in two adjacent subnets is performed through a linkage tree. Though belief update in a Bayesian network is NP-hard [5], it can still be used for intrusion detection since the subnets are usually small.\n\nFigure 4: DAGs of three subnets of an MSBN and JTs constructed from the subnet Figure 4 shows an MSBN with three subnets G0, G1, G2. Each of these subnets contains a group of agents. The LJF method has compiled each subnet into a JT (called a local JT), and has converted each d-sepset into a JT (called a linkage tree). Figure 4 also depicts three local JTs and two linkage trees of the monitoring system. Each oval in a JT or a linkage tree represents a subset of variables and is called a cluster. For instance, {o, i, j} is a cluster in a JT in the subnet G2 and {i, j} is a cluster in the linkage tree between subnets G2 and G0. Local inference is performed by message passing in the\n\nlocal JT. Message passing between a pair of adjacent subdomains is performed using the linkage tree. Once a multiagent MSBN is constructed, agents perform probabilistic inference by computing the query P(x|e), where x is any variable within a subdomain and e is the observations made by all the agents in the system. The system-wide communication among the agents (about e) is vital for sharing of information among agents. However, since the agents are autonomous, the system-wide message passing is infrequent. Most of the time, the agents in subnet Gi computes the query P(x|ei, ei′), where ei is the local observations made by the agents in Gi, and ei′ is the observations made by the agents of other subdomains as recorded in Gi till the last communication. This computation is called local inference. Since LJF has least overhead of inter-agent communication [6], in the proposed system it has been used to minimize network traffic due to inter subdomain message passing.\n\n## 4. Fault-Tolerance and Trust Mechanism\nIn this section, a novel approach for introducing fault-tolerance in the proposed system is described. A distributed trust management scheme is developed among the agents in the system and a robust algorithm based on Byzantine Agreement Protocol (BAP) [7] is invoked among the peer agents. This enables a reliable and fast detection of any compromised agents in the system. If any agent is detected to be compromised, it is immediately isolated from the system. Use of BAP to identify compromised nodes makes the proposed IDS framework reliable, secure and fault-tolerant.\n\n## 4.1. Distributed trust management\nThe agents are always vulnerable to attacks by intruders. If an intruder can compromise a host, the agents in the host will attempt to influence the JT and which will adversely affect the overall inference machinery of the IDS. For early detection of compromised hosts in the proposed system, an efficient trust management scheme based on BAP is developed among the hosts."}]}

The EPO is generated only after a successful comparison of the hash value with the encrypted goods transmitted during the Delivery Phase(D/P). The ALSP specification for the generation of the EPO would be:\n\nelectronicPaymentOrder(sk(U), GoodDescription, Price, hash(f, encryptGoods(K, Goods))):- comparesHash(U), userKnowsEncryptedGoods(U, encGoods(K, Goods)), userKnowsHash(U,hash(f,encryptGoods( K, Goods))). (D)\n\nThe rule(D) ensures that the synthesis of the Electronic Payment Order occurs if and only if the user(U) has a knowledge of the encrypted goods; the hash value transmitted by the vendor(V) and the user(U) has successfully compared the two together. It is evident from the head of the rule that the EPO contains a good description, the money to be debited and the hash value of the encrypted goods which is later forwarded to the NetBill Transaction server(T).\n\n## 4.4  The Optional Phase (O/P)\n[State 1] UT: transaction enquiry Pre-Condition:[State 10(P/P)]\n\n[State 2] TU: ST(receipt, Key) Pre-Condition:[State 1]\n\nThe first step of the Optional Phase(O/P) occurs when the user(U) is unable to get the decrypting key(K) from the vendor(V). The user(U) then enquires the NetBill server(T) about the transaction. The NetBill server(T) in response to the transaction enquiry resends the signed key(K) and the receipt of the transaction with the vendor(V), directly to the user(U). The formal specification of the optiontal transaction enquiry in ALSP would be:\n\ntransactionEnquiry(U, T, transactionenquiry, Time):- not receiveUserReceipt(U,receipt ( sk(T), K, computedReceipt(R)), Time) (E) The rule(E) ensures that a transaction enquiry from user(U) to the NetBill server(T) is true if and only if the user(U) has not received the signed receipt and the key(K) from the server(T) in time. This completes the specification of the protocol. But, a model for a security violation also needs a goal state that corresponds to that attack[3]. While planning an attack on a protocol, we must concentrate on a security guarantee(like authentication, privacy, atomicity), a protocol intends to offer, which we aim to prove is void. An ALSP specification that challenges that guarantee is tested as a goal state. If there exists a model for the challenge, we declaratively conclude that protocol is flawed and there is scope for a violation which corresponds to our specified goal state.\n\n4. Specification of Attacks on NetBill NetBill protocol is used for purchase and sale of information goods[9]. It is imperative for an information goods protocol to be goods atomic[7]. There have been claims both for and against the goods atomicity of the NetBill protocol. Researchers Ogata and Futasugi[10] claimed that the NetBill is not goods atomic. While specifying the goal state, we are following their assumptions about the protocol and check whether our approach is competent enough to specify formally the attack proposed by them. In order to define a goal state that would correspond to security violations challenging the goods atomicity of the protocol, we would have to enable the user(U) to judge a valid decryption of the goods he ordered at the end of the protocol run. To do the same, we add an extra rule in our specification which would judge the validity of the decrypted goods.\n\nuserSuccessfullDecryption(U, Goods):- K1=K, knowsReceipt(U, sk(T), K1, computedReceipt(R)), userKnowsEncryptedGoods(U, encryptGoods(K, Goods)). (F)\n\nThe rule(F) of the protocol specification ensures that there exists a successful decryption of the goods(Goods) if and only if the key(K1) received from the server(T) is the same key(K) with which the vendor(V) had encrypted the goods which were transferred to the user(U). An attack claiming that NetBill is not goods atomic would define a scenario in which the user(U) pays for the goods, but is unable to receive correct goods which it had ordered prior to the payment. Using the concepts of logic programming and planning, we finally specify our goal state.\n\nAttack(U):- not userSuccessfullDecryption(U, Goods, knowsReceipt(U, sk(T), K1, computedReceipt(R)), electronicPaymentOrder(sk(U), GoodDescription, Price, hash(f, encryptGoods(K, Goods))).\n\nThe “Attack(U)” of the specification explains a state in which the user is unable to successfully decrypt the goods at the end protocol run. Although for the same transaction the user(U) had generated an EPO for which a corresponding endorsed receipt(signifying a debit) has been received from the server(T). We now use the SMODELS[6], model generator to test the specification and see if there exists an attack on NetBill. The results vary based on our assumptions about the honesty of the vendor(V) in the protocol. Therefore they have been categorized into the following cases. CASE 1: The vendor is assumed to be honest and does not transmit two different keys for the same transaction.\n\nMODEL GENERATED: 0 userSuccessfullDecryption(U, Goods): TRUE Attack(U)\n\n: FALSE\n\nCASE 2: The vendor is assumed to be dishonest and is capable of transmitting two different keys for the same transaction.\n\nMODEL GENERATED: 1 userSuccessfullDecryption(U, Goods): FALSE Attack(U)\n\n: TRUE\n\nWe are able get a model for our assumption in Case 2. This result corresponds to the result proposed by Ogata and Futasugi[10]. A similar approach for specification can be adopted for other security and transactions protocols as well. Although our results show that NetBill is not goods atomic, it cannot be stated declaratively, as NetBill has a devised contingency mechanism for similar security threats which is external to the protocol scope.\n\n## 4. Specification of NetBill using ALSP\nALSP is based on logic programming with stable model semantics[2]. A logic program is defined by rules. We formalize and frame all actions in a protocol specification as logic program rules[3]. Therefore every time rule holds true, an action is said to be performed and the protocol is assumed to have reached a new state. Following the logic programming approach all rules comprise of a head and a body [2]. The head and the body in each rule is separated by a [:--] to make it syntactically correct for the SMODELS model generator. The left hand side head literals hold true if and only if all the literals on the right hand side body are true. A syntactically correct example of a rule would be: q:- not p, s.\n\nThe above rule is read as “q iff( not p && s)”. Here „q‟, „p‟ and „s‟ are literals and we can state informally that „q‟ is true if and only if „p‟ is not true and „s‟ is true. We start specifying the protocol by considering the basic sort predicates(predicates which are not governed by any rules, mentioned in the specification) first[3]. We state clearly the background theory(initial state of the protocol) which contains all the rules describing, how a message is composed and decrypted by the agents. It includes the property of keys shared and how information is attained by agents participating in a protocol. The basic sort predicates that we will use to specify the NetBill protocol are similar to ones taken from the works of Aiello and Massacci[3]. Though, a few predicates that cater specifically to the NetBill protocol are added intentionally to its specification. They include:\n\nencryptedGoodHashPair(EncGood, Hash (1) goodsDescriptionQuotePair(GD, Quote) (2)\n\nWhile writing the specification it becomes imperative to add basic sort predicates depending on the assumptions that form the basis of the specification. For example, the definition of predicate(1) has enabled us to ensure that for every encrypted good(EncGood) there exists a hash value(Hash) which is specific to the encrypted good. Similarly predicate(2) states that for every goods description(GD) that a customer may forward to a vendor, there exists a quote(Quote) with which the vendor will reply to the customers goods request. The list of predicates that are inculcated is immense and all of them cannot be discussed here. It is also impossible to state and explain the entire protocol specification. So, we will focus on how to write the specification based on the assumptions and the states that a protocol attains during a run. Later, a classical unit action of an agent, which includes receiving a message, deriving information from the message and then replying to it will be specified and explained using ALSP. A protocol specification requires a description of what states the protocol reaches and what are the actions that lead to that state. To do the same, we give a phase wise state analysis of the NetBill[9] protocol. Below each state, is a set of preconditions that must hold true for that state to be attained. The notations used for protocol description are identically similar to the one described in [section 3.1]."}]}

The rule(C) ensures that the state in which a vendor(V) sends a price quote to the user(U) is true if and only if, he has synthesized a price quote for the respective user(U) from which he had received a quote request.

Introduction\nElectronic commerce enables business transactions through the internet, when a direct interaction between the parties in a business deal is seemingly difficult. It operates in an open business environment where it is not mandatory for any trust relationship to hold between the engaging parties. Therefore, the protocols that facilitate the exchange of services over the internet and form the basis of a commercial transaction are inculcated with security features, which aim at minimizing the possibilities of a fraudulent activity. Considering the security of such protocols, besides the assumption that perfect cryptographic techniques ensure inclusion of basic properties like authentication, privacy and integrity into a protocol. There are other characteristics like atomicity[7] that arise at a higher level and are specific to the electronic commerce protocols. Atomic transactions form the corner stone of the modern transaction processing theory[8]. Atomicity is a property which allows us to logically link multiple operations of a protocol, in such a way that either all of them are executed during a protocol run or none of them are. It is important that all electronic commerce systems ensure atomicity as most non atomic systems like Digicash[12] or First Virtua[13] are either too expensive to implement or are severely flawed[7].\n\nIntroduction of formal techniques for verification will not only ascertain the presence or absence of the above mentioned characteristics in the protocols, but would also help analysts in designing and optimizing electronic commerce systems. In view to this, the novelty of this paper is to use a logic programming[5] approach for formally specifying NetBill[9] a prominent electronic commerce protocol. Later, we analyze the claims, both for[11] and against[10] NetBill‟s goods atomicity[7] and reproduce a model for an attack similar to the one proposed in [10]. The paper emphasizes on the use of ALSP (Action Language for Security Protocol)[1] and state based description of the protocol for its analysis and verification. ALSP is an executable specification language for representing security protocols and checking violations they are vulnerable to [1][2]. It is based on logic programming, with stable model semantics [4]. Logic Programming enables one with declarative ease to specify the actions of different agents in a protocol. This includes both the operational behavior of a protocol, along with the possible security attacks of an intruder. A protocol trace is viewed as a plan to achieve a goal and the security attacks become plans, which achieve goals that correspond to security violations. A specification in ALSP, is executable using SMODELS[6] as a model generator. A protocol trace can be written using logic programming with stable model semantics. All stable models for the solution set of logic programs are minimal and grounded in nature, where each atom has a justification in terms of the program [3]. The minimalism and grounded characteristics, make ALSP particularly suitable for specifying payment and transactions protocols; as we are able to derive exactly what happened which lead to a security violation. The model generated by executing the specification also specifies that every action, which occurred during the execution of the specification, has a justification behind it. Similarly if the execution of the specification does not reveals a model then, it can be declaratively stated that there exists no plan to achieve that violation. Specification of a protocol in ALSP requires inculcation of concepts of robotic planning[2]. Security protocols are reframed as planning problems, where agents exchange messages and are subject to attacks by intruders. The initial state of a protocol is defined in terms of messages already exchanged by the agents and information they have derived from them. A goal state is defined as an unwanted state where an attack has already occurred. Actions are specified as exchange of messages amongst agents. If there exists a plan to achieve the goal, we state that the protocol is\n\nflawed with scope for a security violation. A solution to the planning problem if any is a sequence of steps that leads to a goal state, corresponding to an attack. A more explicit discussion on protocol specification using ALSP can be found in the works of Aiello and Massacci[3]. In Section 2 of the paper, we begin with a mention of some important security features for electronic commerce protocols. Section 3 deals with the explanation of the NetBill protocol and the notations used in the paper. The development of the specification for the protocol, using the logic programming techniques is explained in the Section 4. We finally specify attacks on the NetBill protocol and produce our results in Section 5, which is followed by the conclusion of our work.\n\n## 2. Security in Electronic Commerce\nSecurity is a primary concern for all electronic commerce transactions. The security features, as suggested by the PODC Community[14] for electronic commerce protocols include: atomic transactions cryptographically secure protocols secure computations high reliability For our analysis of the NetBill protocol, we will focus only on the aspect of atomicity. Tygar[7] explains the importance of atomicity in electronic commerce. Atomicity as a characteristic can be further classified into three distinct levels. Each level caters to a separate security aspect in a transaction. These levels include money atomicity, goods atomicity and certified delivery [7].\n\n## 2.1  Money Atomicity\nA protocol is stated to be money atomic, if no creation or destruction of money takes place during the protocol run. In simpler terms, during a transaction in a protocol, neither of the participating agents should create nor destroy money which they intend to transfer to the other participating agent of the protocol.\n\n## 2.2  Goods  Atomicity\nGoods atomic protocols effect an exact transfer of goods for money[7]. This characteristic eliminates all possibilities of an agent getting goods without paying for them or vice-versa. All goods atomic protocols are inherently money atomic.\n\n## 2.3 Certified Delivery\nCertified delivery protocols enable all engaging parties, to prove exactly what goods have been delivered through the protocol run. They are extremely helpful in scenarios where both the merchant and the customers are not trusted. All protocols that ensure a certified delivery are also goods and money atomic. As NetBill [9] is intended to be used for the sale and purchase of information goods. Goods atomicity is an important consideration for all information goods protocols. NetBill has previously been proved to be goods atomic[11], we will test the validity of this formally using the logic programming approach and show the richness and competence of ALSP as formal verification language in verifying similar attacks on different protocols.\n\n## 3. The NetBill Protocol\nThe NetBill[9] security and transactions protocol was proposed in the year 1995. NetBill is system for micropayments for information goods on the internet. It provides for strong authentication, privacy and atomicity in payment and delivery of goods. A NetBill transaction model involves three active parties namely, the customer, the merchant/vendor and the NetBill transaction server. Figure 1 gives a brief view of interaction between the different parties in a NetBill transaction model.\n\nFigure 1: Parties in NetBill transaction [9] [ ] Transaction Protocol; [----] Auxiliary Protocol\n\n## 3.1   Notations\nThe notations used throughout the paper to explain the NetBill protocol and its cryptographic operations are:\n\nU, V, T are agents to the protocol. UV: M, can be understood as agent(U) sends the message(M) to the agent(V) in the protocol. U: M, can be understood as agent(U) synthesizes message(M) EG: encrypted goods H(EG): hash value of the encrypted goods(EG) EPO: electronic payment order Sv(M): agent(V)‟s signatures on message(M)\n\n## 3.2 Protocol description\nThe protocol enables a vendor(V) and a user(U) to sell and buy information goods over the internet. The protocol being non-optimistic in nature, the NetBill transaction server(T) acts as a trusted third party and is central to the protocol run. All transactions between the user(U) and the vendor(V) take place with the help of the NetBill server(T) and it is assumed that the server(T) is always online.NetBill has three distinct phases, each of which depends on the success of the previous phases. The negotiation phase is the initial phase, which involves both the user(U) and the vendor(V) agreeing on the prices for the goods and the services to be exchanged. We will not make specific mention of these steps in our design and protocol specification as the security characteristics of privacy, authentication and atomicity are not inherent in the negotiation phase[11].\n\nUV: Price Quote Request VU: Price Quote\n\nThe second phase is a delivery phase which involves the user(U) sending a purchase request(for the agreed prices) to the vendor(V). The vendor(V) then encrypts the ordered goods, along with the hash of the encrypted goods and sends it back to the user(U).\n\nUV: Purchase Request V: EG, H(EG) VU: EG, H\n\nThe payment phase follows the delivery phase in which the user(U) transfers a synthesized electronic payment order(EPO) to the vendor(V). The vendor(V) signs the EPO and concatenates it along with the specific key(K) with which, it had earlier encrypted the goods delivered to the respective user(U). It then forwards this information to the NetBill transaction server(T). The server(T) credits the vendor(V)‟s account with the money from the EPO. It then signs the key(K) forwarded by the vendor(V) and sends it back to the vendor(V). The signature is later forwarded to the user(U) which then decrypts the goods with the relevant key(K).\n\nU: EPO UV: EPO VT: Sv(EPO, K) TV: ST(receipt, K) VU: ST(receipt, K)\n\nThere also exists an optional phase where the user(U) directly communicates with the NetBill server(T), when it fails to receive the signed key from the vendor(V).\n\nUT: transaction enquiry TU: ST(receipt, K)\n\n## 5. Conclusion\nThe logic programming approach for formal verification of security protocols, unlike other methodologies prevents analysts from learning scripting styles that are specific to those methodologies. The syntax is intuitive and generic in nature, which makes specifications more comprehensible to people. Besides, the approach can be used in formal verification of a wide plethora of protocols. A problem with this approach may be that the specification for complex protocols becomes very lengthy and time taking. But, being executable in nature, it enables us to study a generated model, based on the specification of an attack and determine exactly what went wrong during the protocol run. This\n\nproperty comes handy in not only determining security threats, but also designing and optimizing protocols.\n\n## 6. References\n[1] L. Carlucci Aiello and F. Massacci.

Today, the need of security and privacy in active information and communication domains such as e-commerce; mobile technologies and the internet has necessitated the use of security protocols. But the underlying security protocols used in these applications are vulnerable to a variety of attacks, such as message replay, parallel session, data interception and/or manipulation, repudiation and impersonation. Therefore before trusting security protocols, it becomes imperative for a systems designer to have some degree of assurance that these protocols fulfill their intended objectives. Formal verification is the use of mathematical techniques to ensure that a design conforms to some precisely expressed notion of functional correctness. Traditionally, security protocols had been designed and analyzed heuristically. The absence of formal methods for verification could lead to security errors remaining undetected. Formal verification techniques, on the other hand, provide a systematic way of discovering protocol flaws. They can be applied to designs described at many different levels of abstraction, ranging from the gate level, to RTL implementations, and in some cases even to transaction level models described in standardized programming languages [1]. Besides the conformity of correctness, formal methods, when used in the design phases of a system’s development often result in more accurate and lower cost systems. Unfortunately, these protocol verification methodologies are very complex and cannot be easily implemented by protocol engineers [19]. There is also a deep sense of distrust in the academic community about the different verification techniques and their competence in determining prospective design and implementation flaws in complex systems [20, 21]. Therefore through this paper, we intend to present, compare and analyze a few most prevalent approaches towards formal verification of security protocols. To achieve our objective we introduce four well known verification approaches – the sequential programming approach; the logic programming approach; the strand spaces approach and the belief based approach – falling under the broader domains of model checking and logical inference. Each of the above mention methodologies are applied to formally verify the Needham Schroeder Public Key protocol [3] for Lowe’s attack[4]. In the process of doing so, we compare these approaches for their specification ease, competence in determining complex security flaws; and computational costs. We also make an explicit mention of the advantages and limitations of using these approaches in verifying similar systems. In section II of the paper we present our literature study by giving a brief mention of what model checking and logical inference approaches are. Section III, introduces the Needham Schroeder Public Key protocol (NSPK) and the classical Lowe’s attack on it. In the section IV we elaborate on our presented verification approaches by proving the validity of the Lowe’s attack on the NSPK protocol using each approach explicitly. Section V presents a detailed comparison between the approaches explained in section IV. Section VI, gives a brief mention of our intention of future work. Finally, we conclude the paper in section VII, followed by references in section VIII. II. LITERATURE SURVEY Formal verification aims at providing a rigid and thorough means of evaluating the correctness of a security protocol so that even subtle defects can be uncovered. These methods include mathematical analysis dependant on logical analysis or process algebras. Though there are numerous approaches and formal methods that could be employed for verification of a security protocol. These approaches can be broadly classified into two domains namely, model checking and logical inferences. The first approach is model checking [2], which consists of a systematically exhaustive exploration of the mathematical model. Usually this consists of exploring all states and transitions in the model, by using smart and domain-specific abstraction techniques to consider whole groups of states in a\n\nApproaches to Formal Verification of Security Protocols\n\nSuvansh Lal, Mohit Jain, Vikrant Chaplot Dhirubhai Ambani Institute of Information and Communication Technology {suvansh_lal, miohit_jain, vikrant_chaplot}@daiict.ac.in\n\n2\n\nsingle operation and reduce computing time. Model Checking, one of many formal verification methods, is an attractive and increasingly appealing alternative to simulation and testing to validate and verify systems [2]. Given a system model and desired system properties, the Model Checker explores the full state space of the system model to check whether the given system properties are satisfied by the model. In this paper, we present the logic programming approach [5, 6, 10] under the model checker domain, with smodels [25] and lparse [12] as a model finder and grounded program generator respectively. Another suggested includes the sequential programming approach [15] with FDR [27] as its model checker. The second approach is logical inference. It consists of using a formal version of mathematical reasoning about the system. This approach is usually only partially automated and is driven by the user's understanding of the system to validate. The suggested approaches under this domain are BAN Logic [22, 23] and the Strand Spaces approach[24]. III. NEEDHAM SCHRODER PUBLIC KEY PROTOCOL\n\nProposed by Roger Needham and Michael Schroder, NSPK protocol [3] claims to provide mutual authentication between two agents, along with establishing a session between the communicating parties, in a public key cryptography based system. For the description of the protocol we would assume that A and B are two honest agents and S is a trusted server. The notation used is - KPX and KSX are the public and private keys of agent X. Protocol Run: 1) A Æ S: A, B (A requests B's public key from S) 2) S Æ A: {KPB, B}Kss (S responds. B's identity is send along with KPB for confirmation) 3) A Æ B: {Na, A}KPB (A sends a fresh nonce Na to B) 4) B Æ S: B, A (B requests S for A’s public key) 5) S Æ B: {KPA, A}Kss (S sends the public key of A to B) 6) B Æ A: {Na, Nb}KPA (B generates a fresh nonce Nb and sends it back to A, along with A’s nonce Na) 7) A Æ{Nb}KPB (A confirms Nb to B) At the end of the protocol, A and B know each other's identities, and know both Na and Nb. These nonces are not known to eavesdroppers. Attack on the NSPK protocol: Gavin Lowe proposed an attack on NSPK using CSP modeling technique and FDR model checking tool [4]. Lowe claimed that the protocol is vulnerable to Man in the Middle Attack, wherein an adversary I, who is responding to a protocol run initiated by A, can falsely authenticate itself to an agent B as A, by replaying A’s message to B. Thus, B is fooled to belief that a session is established between A and B. In the explanation of the attack and its analysis, we will ignore the messages transmitted to and from a trusted server S (message 1, 2, 4 and 5) which remain unchanged in an attack run. Lowe’s Attack on NSPK: 1.1) A Æ I: {Na, A}KPI (A sends a fresh nonce Na to I) 2.1) I(A) Æ B: {Na, A}KPB (In a parallel run of the protocol, I masquerading as A, relays the message received from A after encrypting it under B’s public key.) 2.2) B Æ I(A): {Na, Nb}KPA (B responds to I’s message) 1.2) I Æ A: {Na, Nb}KPA (I relays B’s message to A) 1.3) A Æ I: {Nb}KPI (A returns Nb to complete protocol run with I) 2.3) I(A) Æ B: {Nb}KPB (I masquerade A and forwards Nb encrypted under B’s public key) In the next section, different verification approaches are applied to formally analyze NSPK protocol for a security violation that corresponds to Lowe’s attack and produce results similar to those stated above. IV. APPROACHES TO FORMAL VERIFICATION A. The Strand Spaces Approach Strand Spaces proposed by Fábrega et al in [24] is a mathematical technique for formal verification of security protocols. A strand represents the chronological sequence of the messages transferred during a protocol run. These messages can be sent or received by either legitimate parties or the adversary. The collection of strands of all the parties participating in the protocol run is known as a Strand Space. This technique provides a distinguished approach for protocol verification with intelligent and reliable proofs even without automated support. It works with the explicit model of possible behavior of system penetrator and also provides clear semantics about data items like nonce and session keys. It also provides proofs of notions of correctness of both secrecy and authentication. It also provides the detailed insight into why certain assumptions are required to prove the correctness. TABLE 1 TERMINOLOGY USED A Message Space. It has two disjoint subsets: • T: set of atomic text messages • K: set of cryptographic keys <σ,a> Signed Term: + represent sent message, - represents received message. (tr, Σ) Trace mapping of a participant. It represents the set of messages sent or received by a participant. Subterm relation. e.g. m {m}K but K {m}K iff K m\n\n3\n\nn1⇒ n2 Node n1 is the immediate causal predecessor of n2\n\nn1→ n2 There is a causal link between the nodes n1 and n2\n\nProof of Needham – Schroeder Public Key Protocol\n\nPROTOCOL AIM: This protocol intends that after the successful run of the protocol, the communicating parties share access to Na and Nb and no other party should have access to these values. DEFINITION: Let ∑ be the NSPK strand space. It is the union of following strands: • Initiator Strand: The Initiator Strand has the trace Init [A, B, Na, Nb]. • Responder Strand: The Responder Strand is complementary to the Initiator strand and has the trace Resp [A, B, Na, Nb]. • Penetrator Strand P. ASSUMPTIONS • Each participant has the knowledge of other participant’s public key. • Each participant has different public key. According to this condition if KA = KB ⇒ A = B and vice versa. • Nonce values {Na, Nb }≠ {A, B}. This implies that name of any participant is not used as nonce value. PROOF Figure 1 represents the ideal NSPK strand space. Here ‘i’ represents the initiator strand while ‘s’ represents the responder strand. Figure 1\n\nPROPOSITION 1: Responder’s Guarantee Given • ∑ is the NSPK strand space and C is a bundle that has the responder strand s with trace Resp[A, B, Na, Nb]; • KA -1 ∉ KP where KP represents the set of keys know to penetrator P; • Na ≠ Nb and Nb originates uniquely in ∑. Then there exists an initiator strand ‘i’ in bundle C with trace Init [A, B, Na, Nb]. Figure 2 Figure 2 represents the legitimate responder’s strand. To prove the proposition we will take help of certain lemmas. We rename node <s, 2> where responder sends message {Na, Nb}KA as a0 and its term as t0. We also refer node <s, 3> where responder receive the message {Nb}KB as a3 and its term as t3. LEMMA 1.1: Nb originates at t0. Proof: By observing Figure 2 we find that Nb a0 which is a positive node. Now the only node preceding a0 on responder strand is <s, 1>. We just have to check that Nb term<s, 1>, i.e. Nb ≠ Na and Nb ≠ A. Both of these follow from our hypothesis. Hence we can say that Nb originates at a0. Next lemma checks that whether the step 3 of the protocol is taken by the legitimate party or the penetrator. LEMMA 1.2: Given set S = { n є C: Nb term(n) ^ t0\n\nterm(n)}. Set S has a minimal node t2. The node t2 is positive and regular. Proof: It can be seen that a3 є S. Hence S is non empty and contains a minimal node a2. Since a2 is minimal node its sign is positive. We will now check that whether a2 lies on a penetrator strand or not. We will examine the possible types of penetrator traces. <+t>: If trace(p) is of this form than Nb = t. This implies that Nb originates on this strand which contradicts the result of Lemma 1.1 <-g>: This trace lacks any positive node and hence cannot be minimal node. <-g, +g, +g>: In this case positive nodes do not have minimal occurrence. <-g, -h, +gh>: In this case positive nodes do not have minimal occurrence. <+K0>: Here K0 є KP. But since from our assumption, text and keys belong to disjoint sets this cannot be possible. <- K0 -1, -{h}K0, +h>: If the positive node is minimal then t0 but t0 {h}K0. Hence K0 = KA."}]}

With the weaker information proved in above lemmas we cannot conclude that i has a trace of the form Init [A, B, Na, Nb]. This is because the responder’s identity is not determined by the term {Na, Nb}KA, which is what this agreement protocol is all about. We can only conclude that strand t belonging to user A has trace Init [A, X, Na, Nb] where X can be some party with which A is communicating. This results corresponds to the Lowe’s attack suggested in section III. B. THE LOGIC PROGRAMMING APPROACH In this section we use ALSP (Action Language for Security Protocols[5, 6] as an efficient specification language to formally analyze the NSPK protocol[3]. ALSP is an executable language for representing protocols and checking for security violations they are vulnerable to [6, 10]. Specification of a protocol in ALSP requires inculcation of concepts of robotic planning[13]. Security protocols are reframed as planning problems, where agents exchange messages and are subject to attacks by intruders. The specification of a protocol in ALSP is viewed as a plan to achieve a goal and the attacks become plans, which achieve goals that correspond to security violations. ALSP is based on LPSM(Logic Programming with Stable Model Semantics) [7, 9]. Logic Programming[8] enables one with declarative ease to specify the actions of the different agents in a protocol. This includes both the operational behavior of a protocol, along with the possible security attacks of an intruder. All stable models[11] for the solution set of logic programs in ALSP are minimal and grounded in nature[9]. Minimalism allows one to determine exactly what happened when a protocol specification was executed. It ensures that all unwanted models are not a part of our solution set. Groundedness, on the other hand ensures that everything present in the solution set has a justification behind its presence[5]. A logic program is written as a set of Horn clauses known as rules. We formalize and frame all actions in a protocol specification as logic programming rules[6]. A rule comprises of a head and a body, separated by a [:-]. The left hand side head literals hold true if all the literals on the right hand side body are true. A syntactically correct example of a rule in logic programming would be: q:- p, s. Let P be the logic program with S being the solution set for P. Then the above rule could be read as, if the literals s and p belong to the solution set S then q must also belong to the solution set S. Here the rule is a constraint on the solution set. To develop the protocol specification for NSPK, initially a general description of the background and action theories pertaining to the protocol is specified in ALSP. This is followed by defining, the choice rules representing the correct execution of the protocol and the actual specification of the protocol dependant itself. Last but not the least; we define a rule corresponding to the security property we want to check. Then, the above specifications are merged and a maximum execution time for the protocol run is determined. Setting bounds on basic objects like nonces, devices, random values, etc we use lparse[12] as a suitable front end to the smodels[25] system to generate a grounded logic program from our specification. Finally this grounded logic program is executed in smodels to find stable models corresponding to violations. Development of Protocol Specification for Needham – Schroeder Public Key Protocol:\n\nWe start specifying the protocol by considering basic sort predicates to characterize the basic components of NSPK. We state clearly the background theory (initial state of the protocol) which contains rules describing, how a message is composed and decrypted by the agents. It also includes the properties of keys shared and how information is attained by agents participating in a protocol. A few basic sort predicates used in our protocol specification are, nonce(N), agent(A) time(T). The names of these predicates are intuitive and represent properties and functions of these predicates. A special sort predicate msg(M) is also defined, which means that M is a valid message that may appear in a protocol run. Then, we specify a few basic constructors that symbolize cryptographic operations, concatenations and hashing of messages as required by the protocol. Table 2, represents a few classical constructs used in the protocol specification. TABLE 2 CONSTRUCTS USED IN NSPK SPECIFICATION encrypt(K, M)\n\nDenotes an encryption of the message M using symmetric key K. concat(A, B)\n\nDenotes concatenation of messages A and B (A||B)\n\nWe also specify predicates that define the properties of messages and keys that are used in the protocol. In addition to this, definition of the ability of agents to construct, send, receive and understand these messages is also an imminent part of our protocol specification. As suggested in [6], the predicate names in most part of our ALSP specification for NSPK are fairly intuitive and represent the action or property after which they are named. Table 3, gives a brief mention of these predicates. TABLE 3 PREDICATE NAMES AND THEIR FUNCTIONS part(M,M1) Denotes M as a submessage of M1 verifier(V,A,B) Denotes V as a verifier shared between agents A and B knows(A,M,T)\n\nDenotes agent A knows message M at time T synth(A,M,T) Denotes agent A synthesizes message M at time T\n\n5\n\nsays(A,B,M,T)\n\nDenotes agent A’s attempt of sending the message M to agent B gets(A,M,T) Denotes agent A’s receipt of message M at time T\n\nHaving known all the constructs and predicates required for our specification of NSPK. We initiate the specification of the background theory, beginning with the messages that can be used in the protocol. In ALSP it is deemed sufficient to specify the valid messages, along with all their sub messages for a protocol run [13,14]. This is an important step which ensures that the ALSP specification is admissible [6, 10]. NSPK being a three step protocol, we can easily distinguish the three messages along with their sub messages, transmitted at different stages of its execution. To enhance the readability of our specification, we have avoided using the sort predicates in the body clause of our rules. We have also used the more prevalent notation(Table 1) for its description henceforth. For example, xor(M1,M2) has been simply written as M1 ⊕ M2 and concat(M1,M2) as M1||M2. The protocol specification should also represent the ability of agents to modify and manipulate messages. msg(encrypt(K, N, A)):-\n\nnonce(N), agent(A), publicKey(K, A). msg(encrypt(K, N)):-\n\nnonce(N), publicKey(K, A). msg(N||A)):-\n\nnonce(N), agent(A). To do this message parts are inductively defined based on the protocol constructors. Most of this specification is independent of the protocol itself and represents message part defining rules, incorporated from [5]. part(M,M):-msg(M). part(M,M1||M2):- msg(M), msg(M1),msg(M2),part(M,M1). part(M, M1||M2):- msg(M),msg(M1),msg(M2),part(M,M2). Modeling of knowledge is also an important aspect of the protocol specification in ALSP. Intuitively, the knows predicate is used for the purpose. This includes modeling the abilities of agents to acquire information from messages they have either received or transmitted. We also define that if an agent possesses the knowledge of a message M2 then, he/she would also possess the knowledge of a message M1 which is a sub message of M2. This enables the agent to extract useful message parts from concatenated or exored messages. knows(A, M, T):- said(A, B, M, T) knows(A, M, T):- got(A, M, T) knows(A, M, T):- knows(A, M1, T), part(M, M1) knows(A, M, T):- knows(A, M1||M2, T), part(M, M1)\n\nSimilarly we specify the ability of an agent to synthesize a message in a protocol run. The rules defining the synthesis of messages ensure that an agent can construct a message if and only if it can construct and thereby knows, all the subparts of that message. synth(A, M, T):-knows(A, M, T) synth(A, prf(M1, M2), T):-knows(A, M1, T),\n\nknows(A, M1, T)\n\nKnowledge modeling, description of messages and specification of the ability of agents to synthesize valid messages in a protocol run concludes our background theory for NSPK. Next, comes the specification of the action theory for the protocol. Most of the specification in this part is protocol independent and we refer to [6] for a detailed description. got(B, M, T+1):-gets(B, M, T) said(A, B, M, T+1):-says(A, B, M, T) got(B, M, T+1):-got(B, M, T) said(A, B, M, T+1):-said(A, B, M, T)\n\nNext we define with the help of a choice rule the receiving of messages by an agent the protocol. The rule below suggests that if A sends the message msg(M) to B at time T, then B may/may not receive it. This relieves us from explicitly modeling the faulty transmission behavior or message interception. gets(B, M, T):-says(A, B, M, T)\n\nWe use similar choice rules to describe the abilities of an intruder. In this protocol description and intruder spy can eavesdrop and receive any message from a protocol run. It can also transmit valid messages to honest agents, given that it is able to synthesize them. gets(spy, M, T):-says(A, B, M, T), A!=spy, B!=spy says(spy, B, M, T):- synth(spy, M, T), B!=spy\n\nWe then define the rules that specify a protocol’s action. This being a protocol dependant part, we have to ensure that desirable constraints are imparted on our solution set. To do this we put the same preconditions to each action in a protocol run, as assumed in our initial description of the protocol. We also specify message validation rules, which enable the agents to proceed in a protocol run, only if a message or its component has been verified. says(A,B,encrypt(K, Na, A),T):-\n\nfresh(Na, T), publicKey(K, B), A!=B\n\nsays(B,A,encrypt(K, Na, Na,T):-\n\ngot(B,encrypt(K, Na, A),T), fresh(Nb, T),\n\npublicKey(K, A), A!=B\n\nsays(A,B,encrypt(K, Nb),T):-\n\nsaid(A,B,encrypt(K, Na, A),T),\n\ngot(A,encrypt(K, Na, Na,T),\n\npublicKey(K, B), A!=B\n\nThis completes our background and action theories for the ALSP specification of the NSPK protocol. In the coming section we formally verify the protocol with the above specification and validate security claims earlier proposed by the protocol. 6\n\nPlanning Attacks on the NSPK\n\nWe specify goals using logic programming rules and execute our specification to see if there exists a model where the particular goal state is attained. If true, we deduce that the protocol can be manipulated to attain the security violation and state declaratively that the protocol is insecure. Similarly if a model is not generated we claim that the security violation can not be achieved hence, the protocol is secure. Again, we incorporate the approach as suggested in [6, 10] to specify our goals in ALSP. For example, a logic programming rule ‘attack1’ representing a state when an adversary has attained a sessions key by manipulating a protocol run could be written as:\n\nattack1(T):-\n\ngot(B,encrypt(Kb,Na),T),\n\nsaid(B,A,encrypt(Ka,Na,Nb),T),\n\ngot(B,encrypt(Kb,Nb),T),\n\nnot said(A,B, encrypt(Kb,Na),T),\n\nnot said(A,B, encrypt(Kb,Nb),T), A!=spy,\n\nB!=spy.

PERFORMANCE ANALYSIS\nPreliminary analysis of proposed algorithms was done with a java program to emulate the desired operations. All the values / sensor readings were randomly generated using predefined mathematical random functions in java packages. In their work, Venkatasubramanian et al [3] present an analysis of randomness, time-variance and distinctiveness characteristics of the keys generated as performance analysis, based on which we present an analysis of our scheme. Randomness is the unpredictable nature of the keys used. In the IAMKeys scheme, randomness of the keys generated by the PRNG is dependent on the seed, which is a function of three parameters—the chosen reference frame, the field in the reference frame, and the value of the field (physiological data). Since each of these values are randomly chosen for each data frame being encrypted, the randomness property of the seed, and hence the key, is preserved. We generated 100 frames of data, and noted the values of the offsets of randomly chosen reference frames and fields. Figure 9 illustrates the randomness of the reference frames and the field number values that were generated in IAMKeys. In case of KEMESIS, the randomness of the keys will be a function of the same three parameters, however, the value of the field is a randomly changing number, and not physiological data. Figure 10 illustrates the randomness observed when 16 reference frames, with 8 fields each were chosen to generate random keys. The randomness in KEMESIS is compounded by the fact that only one of the keys will be used for encryption. Distinctiveness refers to how different the keys are when compared to different individuals. We observed from our simulation of the IAMKeys algorithm that keys are only identical for a person if the readings are exactly identical and the random reference frame or field values generated are the same, which is highly unlikely. In KEMESIS, the distinctiveness can be partly observed, given that only the WCC and the sensors of a given WBAN can have the same values in the reference frame list, since the key refreshes are random.\n\nFigure 9. Simulation of reference frames and field numbers in IAMKeys Time-variance of the keys implies that different instances of time should produce different keys. In a WBAN, not all sensor readings would vary drastically between intervals, and any drastic variation would indicate that the patient might be in distress. The time-variant nature of the keys\n\n110\n\nin both algorithms is a function of the randomness property, and since the keys generated are random, we can say that they are time-variant as well.\n\nFigure 10. Simulation of reference frames and field numbers in KEMESIS We analyze the complexity of the algorithm by determining the number of logical operations performed in the encryption and decryption of one data frame. However, for analysis purposes, we make the following assumptions: • Data in each field of the frame is 8-bits. • The PRNG is implemented using 8-bit Linear Feedback Shift Registers (LFSR). • Reference frame and field numbers are randomly identified by numbers generated using 4-bit LFSRs. • For addition operation, we consider the use of a full adder circuit for adding each bit, which employs 2 XOR gates, 2 AND gates and 1 OR gate. Hence, each bit addition will contribute to 5 logical operations [8]. • For sender authentication in IAMKeys, hash operation is performed on the sum of all data values in the reference frame. If α+1 is the number of fields in the frame, then, there will be α extra additions during encryption/decryption. • For sender authentication in KEMESIS, hash operation is performed only on the value in the field identified. Hence, α is not considered. • We have assumed that reference frame list refresh and frame transmission do not count as logical operations, and thus, have not included these numbers in the calculations in table 2 or table 4. • β represents the tone value. • γ represents the presence or absence of a frame refresh following an acknowledgement frame reception. • Hash operation is assumed to be one-bit circular left shift operation, contributing to one logical operation. Table 1 highlights the various logical operations in key generation and encryption/decryption of one frame using IAMKeys. Table 2 presents the total number of logical operations, with calculations based on assumed values for α, β and γ listed in table 1. The major contributing factor to the total logical operations is the sender authentication, which decides the value of β.\n\n111\n\nTable 1.

During the WBAN deployment, the administrator loads these reference frames with identical dummy values at both the WCC and the monitoring station data receiver. When the receiver successfully receives the sent data frame, it sends an acknowledgement (ACK) to the WCC, along with the sequence number. Then, the receiver waits for one more reception, and updates its reference frame list. Upon reception of the ACK, the WCC proceeds to update its reference frame list. The reference frame list is updated as follows. The sender (or, receiver) checks for the oldest reference frame in its list. This is assumed to be the frame with the oldest sequence number. The system then replaces this reference frame with the acknowledged frame.\n\n## 3.2.2   Sender Authentication and Tone\nEach encrypted data frame that is transmitted is appended with the sequence number of the reference frame used for generating the key, the field number in this reference frame whose value is used as the seed, a “Tone” value, and a sender authentication code.\n\nFigure 5. Structure of the transmitted frame The transmitted frame is as illustrated in figure 5. The tone is a random number between 1 and 5, generated for each data frame. To generate the sender authentication code, the reference frame that was chosen to generate the encryption key is hashed the number of times indicated by the Tone value of that frame. This is analogous to generating a digital signature of the sender on the fly for each transmitted frame. The receiver repeats this process by retrieving the reference\n\n104\n\nframe pointed by the reference-frame-sequence-number that was received as part of the transmitted message to authenticate the sender. The value of the tone has a minimum value of 1so as to ensure that the reference frame is hashed at least once, and has a maximum value of 5 to ensure that the hashing process does not become increasingly computationally expensive.\n\n## 3.2.3   Key Generation and Management\nAfter aggregating values for the data frame, the WCC proceeds to generate the keys for encrypting the current frame. It begins by randomly choosing one of the five reference frames, and one of the data fields of the chosen frame. The value of this field will be used as the seed for the PRNG, whose output will be the key, K1, which is logically inverted to generate key, K2. To avoid exchange of the keys, the WCC appends the sequence number of the reference frame and the field number in this frame as REF_FRM_SEQ_NO and FIELD_NO, respectively, in the transmitted frame. The receiver, after authenticating the WCC, initiates the key generation process by first retrieving reference frame sequence number, followed by the field number. The receiver then retrieves the value of the particular field from its reference frame list, and uses this value (could be any biometric value in the reference data frame) as the initial seed for the PRNG to generate K1 and inverts it to obtain K2. The key generation operations are summarized in equations (1) and (2). These are the two keys that are used for the encryption and decryption processes, and are independently generated at both the sender and the receiver. K1 = PRNG (SEED)\n\n(1) K2 = INVERT (K1)\n\n(2) where, PRNG  = Pseudorandom number generator; SEED = Value of the field pointed by FIELD_NO, in the reference frame pointed by REF_FRM_SEQ_NO; and, INVERT  = Logical inversion operation\n\n## 3.2.4   Data Encryption\nOnce the keys are generated, the WCC proceeds to encrypt the data. The encryption process is a combination of the concepts of block and stream ciphers, to ensure a simple encryption process that is also slightly complex. This proceeds as follows. At the time of data aggregation, the WCC assembles data as blocks of k bits. This is to avoid the additional computation required to divide the aggregated frame into blocks of the specified size. The k bit blocks of data and the keys, K1 and K2, are then divided into equal halves. The encryption involves two rounds, one for each key. In the first round, the left half of the data is encrypted (XORed) with the right half of K1 to yield the right half of the intermediate frame, and the right half of the data is encrypted with the left half of K1 to yield the left half of the intermediate frame. The intermediate frame is the output of the first round of encryption. In the second round, the same logic as above is applied to the intermediate frame with K2. The left half of the intermediate frame is XORed with right half of K2 to yield right half of the encrypted frame, and the right half of the intermediate frame and left half of K2 are XORed to yield left half of the encrypted frame. Thus, after two rounds of encryption, the order of the data is preserved, but data is encrypted using a complex mechanism. Figure 6 summarizes the encryption process, and the operations are summarized in equations (3) and (4). E1 = [ XOR (RHD, LHK1) | XOR (LHD, RHK1) ]\n\n(3) E2 = [ XOR (RHE1, LHK2) | XOR (LHE1, RHK1)]\n\n(4)\n\n105\n\nwhere, E1, E2 = Encrypted frames after round 1 and round 2, respectively; XOR  = The logical XOR function, that performs exclusive OR operation on its arguments; LHD, RHD = Left and Right halves of the Data frame; LHE1, RHE1 = Left and Right halves of the Intermediate encrypted frame (after round 1); and, LHK1, RHK1, LHK2, RHK2 = Left and Right halves of the keys, K1 and K2, respectively.\n\nFigure 6."}]}

The challenge is to promptly react to fastly mutating needs by deploying custom traffic analyses, capable of tracking event chains and multi-stage attacks, and efficiently handle the many heterogeneous features, events, and conditions which characterize an operational failure, a network application mis-behavior, an anomaly or an incoming attack. Such needed level of flexibility and programmability should address scalability by design, through systematic exploitation of stream-based analysis techniques. And, even more challenging, traffic analyses and mitigation primitives should be ideally brought\n\ninside the monitoring probes themselves at data plane, so as to avoid exporting traffic data to central analysis points, an hardly adequate way to cope with the traffic scale and the strict (ideally real time) mitigation delay requirements. Figure 1: StreaMon data plane identification/measurement/decision abstraction, and its mapping to implementation-specific workflow tasks\n\nTo face this rapidly evolving scenario, in this paper we propose StreaMon, a data-plane programming abstraction for stream-based monitoring tasks directly running over network probes. StreaMon is devised as a pragmatic tradeoff between full programmability and vendors’ need to keep their platforms closed. StreaMon’s strategy closely resembles that pioneered by Openflow [25] in the abstraction of networking functionalities, thus paving the road towards software-defined networking 1 1\n\n1\n\nAnd in fact, even if the focus of this paper is (as a first step) only on the data plane interface itself, we believe that StreaMon could eventually candidate to play the role of a possible southbound data-plane interface for Software-Defined Monitoring frameworks, devised to translate high level monitoring tasks into a sequence of low-level traffic analysis programs distributed into network-wide StreaMon probes.. However, the analogy with Openflow limits to the strategic level; in its technical design, StreaMon significantly departs from Openflow for the very simple reason that (as discussed in Section 2) the data-plane programmability of monitoring tasks exhibits very different requirements with respect to the data-plane programmability of networking functionalities, and thus mandate for different programming abstractions. The actual contribution of this paper is threefold. (1) We identify (and design an execution platform for) an extremely simple abstraction which appears capable of supporting a wide range of monitoring application requirements. The proposed API decouples the monitoring application “logic”, externally provided by a third party programmer via (easy to code) eXtended Finite State Machines (XFSM), from the actual “primitives”, namely configurable sketch-based measurement modules, d-left hash tables, state management primitives, and export/mitigation actions, hard-coded in the device. While our handling of sketch-based measurement primitives may recall [34], we radically differentiate from any other work we are aware of, in our proposal to inject monitoring logic in the form of XFSM devised to locally orchestrate and run-time adapt measurements to the tracked state for each monitored entity (flows, hosts, DNS names, etc), with no need to resort to an external controlling device. (2) We implement two StreaMon platform prototypes, a full SW and a FPGA/SW integrated implementation. We functionally validate them with five use case examples (P2P traffic classification, Conficker botnet detection, packet entropy HW analysis, DDos detection, Port Knocking), not meant as stand-alone contributions, but rather selected to showcase the StreaMon’s adaptability to different application requirements. (3) We assess the performance of the proposed approach: even if the current prototype implementation is not primarily designed with performance requirements in mind, we show that it can already sustain traffic in the multi-gbps range even with several instantiated metrics (for example 2.315 Gbps of real world replayed traffic with 16 metrics, see section 5.2); moreover, we show that scalability can be easily enhanced by offloading the SW implementation with HW accelerated metrics; in essence, it seems fair to say that scalability appears to be an architectural property of our proposed API, rather than a side effect of an efficient implementation. 2 StreaMon abstraction\n\nOur strategy in devising an abstraction for deploying stream-based monitoring tasks over a (general-purpose) network monitoring probe is similar in spirit to that brought about by the designers of the Openflow [25] match/action abstraction, for programming networking functionalities over a switching fabric. Indeed, we also aim at identifying a compromise between full programming flexibility, so as to adapt to the very diverse needs of monitoring application developers and permit a broad range of innovation, and consistency with the vendors’ need for closed platforms. However, the requirements of monitoring applications appear largely different from that of a networking functionality, and this naturally drives towards a different pragmatic abstraction with respect to a match/action table. At least three important differences do emerge. First, the “entity” being monitored is not consistently associated with the same field (or set of fields) in the packet header. For instance, if the target is to detect whether an IP address (monitored entity) is a bot, and the chosen mechanism is to analyze if the percentage of DNS NXDomain replies (feature) is greater than a given threshold (condition), the flow key to use for accounting is the source IP address when the arriving packet is a DNS query (event), but becomes the destination IP address when the packet is a DNS response (a different event). Second, the type of analysis (and possibly the monitoring entity target) entailed by a monitoring application may change over time, dynamically adapting to the knowledge gathered so far. For instance, if an IP address exhibits a critical percentage of DNS NXDomain replies, hence a bot suspect, we may further track its TCP SYNACK/SYN ratio and determine whether horizontal network scans occur, so as to reinforce our suspicion. And we might then follow up by deriving even more in-depth features, e.g., based on deep packet inspection. But at the same time, we would like to avoid tracking all features for all the possible flows, as this would unnecessarily drain computational resources. Finally, activities associated to a monitoring task are not all associated to a matching functionality: only measurement and accounting tasks are. Rather, less frequent, but crucial, activities (such as forging and exporting alerts, changing states, setting a mitigation filtering rule, and so on) are based on decisions taken on what we learned so far, and which are hence triggered by conditions applied to the gathered features. Our proposed StreaMon abstraction, illustrated in figure 1, appears capable to cope with such requirements (as more extensively shown with the use cases presented in section 4). It comprises of three “stages”, programmable by the monitoring application developer via external means (i.e. not accessing the internal probe platform implementation). (1) The Identification stage permits the programmer to specify what is the monitored entity (more precisely, deriving its primary key, i.e., a combination of packet fields that identify the entity) associated to an event triggered by the actual packet under arrival, as well as retrieve an eventually associated state 2 2\n\n2\n\nOur implementation uses d-left hashes for O(1) complexity in managing states. Also, memory consumption can be greatly reduced by opportunistically storing only non-default (e.g. anomalous) states. See the illustrative experiment in Fig. 2 for a rough idea of the attainable saving in the Conficker detection example, use case 4.2.. (2) The Measurement stage permits the programmer to configure which information should be accounted. It integrates hard-coded and efficiently implemented hash-based measurement primitives (metric modules), fed by configurable packet/protocol fields, with externally programmed features, expressed as arbitrary arithmetic operations on the metric modules’ output. (3) The Decision stage is the most novel aspect of our abstraction. It permits to take decisions programmed in the form of eXtended Finite State Machines (XFSM), i.e. check conditions associated to the current state and tested over the currently computed features, and trigger associated actions and/or state transitions. Figure 2: Experimental analysis of number of NXDomain DNS responses received (a feature commonly used in Botnet detection, e.g., [22]). Data obtained using a trace of 155 minutes with 955 different hosts belonging to 36 different /24 subnetworks. (a): Number of DNS NXDomain responses received per host (430 IPs performing at least 1 DNS query, 401 of them don’t receive any NXDomain response); (b): number of tcp packet per seconds for all the flows (pkt1) and only for the flows for which (pkt2), 15 minutes sample; analysis time for whole pkt1 trace: 1179 seconds, versus 68 seconds for pkt2. The obvious compromise in our proposed approach is that (as per the match/action Openflow primitives) new metrics or actions can only be added by directly implementing them over the monitoring devices, thus extending the device capabilities. However, even restricting to our actual StreaMon prototype, the subset of metrics we implemented appear reusable and sufficient to support features proposed in a meaningful set of literature applications - see Table 1 in Section 3.2. 3 StreaMon Processing Engine\n\n3.1 System components\n\nThe previously introduced abstraction can be concretely implemented by a stream processing engine whose architecture is depicted in Figure 3. It consists of four modular layers descriptively organized into two subsystems, namely Measurement subsystem and Logic subsystem, detailed in sections 3.2 and 3.3, respectively. Event layer - Such layer is in charge of parsing each raw captured packet, and match an event among those user-programmed via the StreaMon API. The matched event identifies a user-programmed primary key which permits to retrieve an eventually stored state. The event layer is further in charge of supplementary technical tasks (see section 3.3), such as handling special timeout events, deriving further secondary keys, etc. Metric layer - StreaMon operates on a per-packet basis and does not store any (raw) traffic in a local database. The application programmer can instantiate a number of metrics derived by a basic common structure, implemented as computation/memory efficient multi-hash data structures (i.e., Bloom-type sketches), updated at every packet arrival. Feature layer - this layer permits to compute user-defined arithmetic functions over (one or more) metric outputs. Whereas metrics carry out the bulky task of accounting basic statistics in a scalable and computation/memory efficient manner, the features compute derived statistics tailored to the specific application needs, at no (noticeable) extra computational/memory cost. Decision layer - this final processing stage implements the actual application logic. This layer keeps a list of conditions expressed as mathematical/logical functions of the feature vector provided by the previous layer and any other possible secondary status. Each condition will trigger a set of specified and pre-implemented actions and a state transition. Figure 3: StreaMon processing engine architecture\n\nFigure 4: Excerpt of XML based StreaMon code showing: (i) metric element allocation, (ii) feature compositions, (iii) an event logic description. In particular this picture shows a timeout event handler, described in terms of metric operations, feature extractions, conditions, actions and state transition\n\nStreaMon’s programming language\n\nApplication programmers describe their desired monitoring operations through an high-level XML-like language, which permits to specify custom (dynamic) states, configure measurement metrics, formalize when (e.g.in which state and for which event) and how (i.e. by performing which operations over available metrics and state information) to extract features, and under which conditions trigger relevant actions (e.g. send an alert or data to a central controller). We remark that a monitoring application formally specified using our XML description does not require to be compiled by application developers, but is run-time installed, thus significantly simplifying on-field deployment. Figure 4 shows an excerpt of a StreaMon application code. HW acceleration\n\nStreaMon allows the seamless integration of HW accelerated metrics, e.g. mandated by stringent performance requirements. This remains transparent to the application programmer, which can thus port the same application from a SW based probe to a dedicated HW platform with no changes in the application program. Seamless HW integration is technically accomplished by performing all metrics, parsing, and event matching HW-accelerated computations in a front-end (in our specific case, an FPGA), and by bringing the relevant results up to the user plane through a HW/SW interface, by appending the meta-data generated by the HW tasks to the packet. 3.2 Measurement Subsystem\n\nThe StreaMon Measurement subsystem provides a fast, computation/memory efficient, set of n highly configurable built-in modules that allows a programmer to deploy and compute a wide range of traffic features in stream mode. Multi-Hash Metric module (MH) - From a high level point of view, StreaMon metric modules are functional blocks exporting a simple interface to update and retrieve metric values associated to a given key. Even though in principle such modules can be implemented with any compact data structure compatible to our proposed stream mode approach (and indeed the current architecture support pluggable user defined metric modules), several metrics of practical interest can be derived from a basic structure depicted in Figure 5 and extending the construction proposed in [5]. It permits to count (or time-average, see below) distinct values (called variations in [5]) associated to a same key; for example: the number of distinct IP destinations contacted by a same IP source, or the number of distinct DNS names associated to a same IP address."}]}

At deployment time, an MH module is configured by: (i) enabling/disabling the VD or the VM; (ii) specifying the counting data structure in the VM; (iii) setting the MH parameters, i.e., number of hash functions, total memory allocated, swapping threshold [5] or memory time window in the VD, TBF’s smoothing parameter [6]; (iv) chain multiple MH module (so as to update a metric only if a former one was updated). At run time, the programmer may dynamically change flowkeys and updating quantities. In particular, for each possible event and (if needed) flow status (i.e., XFSM entry), a list of Metric Operations (MOP) is defined, where a MOP is a set/get primitive that defines the flowkeys (as a packet fields combinations) and quantities to be monitored/accounted. Finally, a set of StreaMon metrics are combined into Features by simply defining mathematical functions, where is a Metric vector. What practical features can be supported? - We believe that the above metrics fulfill the needs of a non negligible fraction of real world monitoring applications. Indeed, [6] shows a concrete example of a real world application reimplemented by just using modules derived from our general MH module described above. Indeed, limiting to the StreaMon’s measurement subsystem (we will significantly extend the framework in the next section), table 1 shows features considered in a number of works taken from a somewhat heterogeneous set (different targets, operating at different network layers, different classification approaches) which, according to our analysis, are readily deployed through suitable configuration of the above metrics/features. Indeed, most applications either require to track/match (1) features that are directly retrievable from a single packet and do not have memory of past values (e.g.: short life of a DNS domain, message body length, all the features in [17] except the first one); and/or (2) require counting or averaging over a various set of parameters (eventually uniquely accounted - e.g. variations), which are readily instantiated with an MH module 4 4\n\n4\n\nFor instance, the number of bytes exchanged between two hosts can be obtained by setting as VMK is the concatenation of source and destination IP address and as updating quantity the length field of the packet; similarly, unique counts such as the\n\ntotal number of distinct TTL for a given DNS domain is obtained by setting as VDK the concatenation of Domain Name and TTL in the DNS response and as VMK is the Domain Name.; and/or (3) require logical/mathematical combinations of different statistics, which is the goal of our Feature Layer. Traffic features not covered by the families listed above are those which require a stateful correlation of different flows status. Such metrics (like the ones exploited in [33]) are supported by StreaMon but require the stateful framework described in Section 3.3. 3.3 Logic subsystem\n\nStreaMon’s Logic Subsystem is the result of the interwork between the Event Layer and the Decision Layer. It provides the application developer with the ability to customize the tracking logic associated to a monitored entity subject to specific user-defined conditions, so as to provide a verdict and/or perform analyses beyond those provided by the Monitoring Subsystem. Event Layer - The Event Layer generates the events triggering the StreaMon processing chain, identifies the monitored entity (primary key), and retrieves the specific event context (in particular the flow status). This layer is further composed of three functional component: (i) the capture engine responsible for “capturing” the triggering event, either a “packet arrival” or a “timeout expiration”;(ii) the timeout manager in charge of keeping track of all registered timeouts and manage their expiration; (iii) the status table, a (dleft hash) table storing the status associated to the processed flows - the primary key status - and the so-called secondary support table, a table storing states not associated to the primary key but required by the application state machine to take some decision. The triggering event is associated to a primary key, i.e. the monitored entity (flow, host, etc) under investigation for which the monitoring application will provide a final verdict, like “infected” or “legitimate”. For intercepted packets, the primary key is a combination of packet fields parsed by the (extensible) protocol dissector implemented in this layer. For locally generated timeout expiration events, the primary key is retrieved from the timeout context. The primary key is used to retrieve the current status of the flow: no match in the state table is considered to be a default state. If the primary key is not directly retrievable from the packet, and instead the flow status is related to some other flow previously processed, a secondary support table storing the references to the entries in the status table is used. Such secondary support table is called related status table. For example, this can be the case of an application keeping track of SIP URIs, (i.e.: the primary key is the SIP user ID in SIP INVITE messages) and consider as suspicious all UDP packets related to a data connection with a suspicious SIP user. In case of UDP packets, neither of the packet fields can be used to retrieve the flow status. Instead, a secondary support table is used to keep a reference between the socket 5-tuple and the status entry of the associated SIP initiator user. If the application does not take into account the flow status, the primary extraction is skipped. Decision Layer - The Decision Layer is the last processing unit of the StreaMon architecture and receives the event context carrying an indication of the current flow status and a set of traffic features container. This layer keeps a list of Decision Entries (DEs) defined as the 3-tuple (enabling Condition (C), Output actions (O), State Transition (ST)). For each triggering event, and according to the current flow status, the decision layer verifies the enabling conditions and executes the actions and the state transition associated to the matched condition. Since secondary support tables can be updated, StreaMon support variable conditions, i.e. in which the comparison operands may change during time. The first matched condition will trigger the execution of a action set (like DROP, ALERT, SET_TIMEOUT etc..). Programming the Logic Subsystem - Programmers describe an XFSM specifying (i) states and triggering events; (ii) for each state, which metrics and features are updated and which auxiliary information is collected/processed (secondary table); (iii) which conditions trigger a state transition and the associated actions. Logic Subsystem built-in primitives\n\nOperators\n\nSUM, DIFF, DIV, MULT, MOD\n\nEQ, NEQ, LT, GT, SQRT, LOG, POW\n\nAND, OR, NOT, XOR\n\nActions\n\nSET_TIMEOUT, UPDATE_TIMEOUT\n\nSAVE_TIMEOUT_CTX, DROP, ALLOW, MARK\n\nNEXT_STATUS, UPDATE_TABLE, PRINT, EXPORT\n\nTable 2:\n\nTo identify the triggering event, StreaMon keeps a list of user-defined “event descriptors”, expressed as a 3-tuple (type, descriptor, primary key). For example, in case of intercepted packets, an event can be defined as:. Moreover, programmers are given primitives to define for each event and state: (i) a set of metric operations (MOP) as described in section 3.2; (ii) a set of conditions expressed as an arithmetic function of features and secondary support table values. For each condition, programmers define a set of built-in actions and a state transition. Table 2 summarizes the logic subsystem supported condition operators and actions. 4 Simple Use case examples\n\nFigure 6: Application XFSMs: (a) Conficker use case; (b) DDOS use case\n\nWe use the following simple examples to highlight the flexibility of StreaMon in supporting heterogeneous features commonly found in real-world monitoring applications. The input data traces are obtained by properly merging a packet trace gathered from a regional Internet provider with either (i) real malicious traffic extracted from traces captured in our campus network (use case 4.1 and 4.2) or (ii) synthetic traces properly generated in our laboratories (use case 4.3). 4.1 P2P traffic classification\n\nThis example shows how straightforward is the implementation of three transport layer traffic features described in [20], for detecting peer to peer protocols that use UDP and TCP connections. The (stateless) application considers the following packet events (which will ignore well known UDP and TCP ports.):\n\nThis application extracts the following traffic features; where:\n\n: VD enabled - return 1 for each IP src/dst pair which previously opened a {UDP, TCP} socket, 0 otherwise;\n\n: VD enabled and VM type CBF - count the number of different {TCP source ports, hosts} connected to the same destination IP address. Metrics are read/updated on the basis of the matched event, as follows:\n\n;\n\nThe application detects a p2p client if the following condition holds after a transitory period:. 4.2 Conficker botnet detection\n\nConficker is one of the largest Botnets found in recent years [29]. A multi-step detection algorithm can attempt to track the two following (separated) phase: (1) a bot tries to contact the C&C Server, and (2) a single bot tries to contact and infect other hosts. To contact the C&C Server, infected hosts perform a huge number of DNS queries (with a high NXDomain error probability) to resolve randomly generated domains. In the infection phase, every host tries to open a TCP connection to the ports 445 of random IPs."}]}

These metrics are combined into the following features:,.\n\n## Introduction (continued)\nFor a DNS NXDomain response, the condition is checked. If the condition is true, the state of the actual flow changes to alert and an event timeout is set. In the alert state the application updates and and, when this timeout expires, these metrics are used to compute and to verify the related condition: if the condition is true, then the host is considered infected and goes to the next state, otherwise it returns to the default state.\n\nThe application XFSM is graphically described (with simplified syntax) in Figure 6.a. Figure 7 shows the trend of features used in this configuration, for an host infected by Conficker (A) and for a clean host (B). In the first case, the value of is relatively high since the beginning of the monitoring (due to the presence of reverse DNS queries, easily filtered by the application); the value increases when the host starts to perform Conficker queries. The value of instead is very low, clearly denoting a port scan. Also for the host B the presence of rDNS queries increases the value of and this involve a change of state, and the application starts to analyze TCP feature. However the value (nearly 100% of SYNACKs are received) reveals that this is clearly not a network scan. Testing this configuration in a 90-hours trace with 53 different hosts in idle state, we obtained 100% of detection (8 infected hosts detected) without false positive or false negative.\n\nFigure 7: Conficker features temporal evolution\n\n4.3 DDOS detection and mitigation\n\nIn this section we sketch a simple algorithm which can be used as an initial base for detecting and mitigating DDOS attacks. The algorithm is driven by the number of SYN packets received by possible DDOS targets. The XFSM of this configuration is depicted in 6.b, and is governed by the following two events:\n\nMetric (VD=off, VM=TBF) tracks the number of TCP SYN addressed to a same target in 60 seconds (with 240s TBF’s memory). All external servers for which is under a given threshold (100 in this example) are in default state (because they are obviously not under attack and thus do not need an explicit status). When exceeds this threshold, the target goes in monitored state, a timeout is set and the current value of value is stored into a secondary support table with key ip.dst. As soon as this timeout expires, the difference between the current feature value and the one stored is computed. If the condition, holds for two consecutive times, i.e. the rate of TCP SYN has increased twice for more than 20%, the flow goes into an attack state.\n\nOur use case example mimics this mitigation strategy by considering legitimate all the source hosts that have already shown meaningful activity and contacted the server before the actual emergence of the attack, and thus likely dropping most of the TCP SYN having a spoofed source IP address. In our use case example, a second metric tracks the TCP SYN rate, smoothed over a chosen time window, at which which each host contacts each destination IP addresses ( is configured with VD disabled and VM of type TBF with smoothing window 240s, and it is updated with MFK.\n\nFigure 8: DDOS temporal representation: (i) DDOS target host status (red curve), (ii) value for the DDOS target (blu curve) and (iii) for two different legitimate traffic sources connecting to the DDOS target server\n\nFigure 8 shows the temporal evolution of the state of a server, in an experiment where we performed a DDoS attack, with spoofed TCP SYN packets, after about 140s. The figure also reports the measured TCP SYN rate, as well as the traffic generated by two hosts performing regular queries towards the server: one starting at time 0, and the other starting right in the middle of the attack. When the actual attack is detected, the mitigation strategy starts filtering traffic. Thanks to the second tracked metric,, the user starting activities before the DDoS attack is not filtered; on the contrary, connections from sources not previously detected via the metric are blocked, as shown by the green curve. New connections can be accepted as soon the server leaves the attack state (see the growth of the second host).\n\n4.4 HW accelerated detection of non standard encrypted traffic\n\nThis example shows how HW metrics can be integrated in StreaMon. Since one of the task performed during deep packet inspection is the collection of statistics on byte frequencies, offsets for common byte-values, packet information entropy, we illustrate an use case that is a simplified version of the approach described in [14], in which encrypted flows are detected by combining two traffic features: (i) the bit information entropy of a packet; (ii) the percentage of printable characters, ASCII characters in the range. Both features are computationally demanding for a software implementation, whereas they are best delegated to an FPGA implementation (just 250 logic cells for our implementation).\n\nThis use case implements a simple stateless StreaMon application with the following characteristics: (i) it considers as event the reception of a UDP or TCP packet with length greater than 100 bytes; (ii) the primary key is the socket 5-tuple of the packet; (iii) it makes use of two FPGA precomputed metrics: popcount (number of bit set to 1) and printable chars percentage (which is directly mapped into a StreaMon feature); (v) the packet entropy Feature is obtained as, where. An encrypted flow is detected if:\n\nwhere is the entropy of a packet with uniform distribution of 1 in the payload and length and is the standard deviation. Figure 9 shows and to the simple case of HTTP (unencrypted flow) and SSL (encrypted flow) traffic, and as in [14] justify the condition expressed above.\n\nFigure 9: (a) percentage of printable character as function of the percentage of packets (b) percentage of bit set to 1 as function of the percentage of packets\n\n4.5 Port knocking\n\nThis use case shows how a stateful firewall application can be easily implemented with StreaMon. In particular, this use case implements a port knocking mechanism to enable SSH access. The application’s XFSM is depicted in figure 10. SSH access will be granted only to those clients guessing the correct port sequence 5000, 4000, 7000 (a short sequence only for presentation convenience).\n\nThe application considers four events (TCP SYN received respectively on port 5000, 4000, 7000, other ports) and four states (default, 5000contacted, 4000contacted, allowed). A state transition is triggered only if the client (identified by the IP source address) contacts the expected port in the sequence. If after a state transition the next expected port is not contacted in five seconds, the flow status is rolled back to default.\n\nIn addition, to avoid random port scanning for guessing the correct sequence, a metric (VD=ON, VM=TBF with smoothing window 5s) counting the SYN rate is used. If a port scan is detected  the flow status is updated to \"attack\", the host is blocked for 2 minutes and an alert is generated. M1 is updated with and when a SYN to an unexpected port is contacted.\n\n5 Performance evaluation\n\nFigure 10: Port Knocking use case XFSM\n\n5.1 Implementation Overview\n\nWe experimented StreaMon on two platforms. A SW-only deployment leverages off-the-shelf NIC drivers, integrating the efficient PFQ packet capturing kernel module [8]. To test HW acceleration, we also deployed StreaMon using a 10 gbps Combo FPGA card as packet source. In what follows, unless otherwise specified (specifically, section 5.2.3 which deals with HW accelerated metrics implemented over the Combo FPGA card) we focus on the SW-only configuration.\n\nStreaMon start-up sequence is summarized as follows. The application program is given as input to a pre-processor script as a XML formatted textual file. The program is parsed, StreaMon process is configured and executed while in parallel the interpreted feature and condition expressions are transformed them into C++ code and build a \"on-demand DLL\" 5 5\n\n5\n\nNote that this is an optimization step which is devised to on-the-fly compile (transparent to the programmer), the application code, so as to avoid a ”feature/condition interpreter”, which would have lowered the overall performance and would not have permitted line rate feature computation and condition verification. Since no recompilation of the StreaMon code is ever needed, but user defined features are integrated as a DLL, dynamic deployment of user programs is made possible.\n\n;\n\nStreaMon implementation takes advantages from multicore platforms by implementing parallel processing chains as shown in the implementation architecture depicted in figure 11 (for the SW-only setup). The PFQ driver is used as packet filter and configured with a number of software queues equal to the number of cores. Traffic flows are dispatched from the physical queues of the NIC by the PFQ steering function. For each PFQ, a separate StreaMon chain is executed by a single thread with CPU affinity fixed to one of the available core and share the metric banks, status tables and timeout tables (the concurrent access to the shared data is protected by spinlocks).\n\nThe throughput measurement has been performed on a Intel Xeon X5650 (2.67 GHz, 6 cores) Linux server with, 16 GB ram and Intel 82599eb 10Gbit optical interfaces.\n\nFigure 11: StreaMon prototype implementation architecture\n\n5.2 Performance Analysis\n\n5.2.1 Measurement subsystem performance\n\nFigure 12 shows the processing throughput expressed as percentage of the maximum throughput (6,468 Gbps) obtained with one PFQ source block without the overhead of StreaMon, expressed as function of the number of metrics (1, 4, 8, 16, 24, 32) in case of (1, 2, 3, 6) CPU core parallel processing.

A Monitoring API for programmable HW network adapters is proposed in [31]. On top of such probe, network administrators may implement custom C++ monitoring applications. One of the developed applications is Appmon [4]. It uses deep packet inspection to classify observed flows and attribute these flows to an application. Flow states\n\nare stored in an hash table and retrieved when an old flow is observed again. This way to handle states bears some resemblance with that proposed in this work, which however makes usage of (much) more descriptive eXtended Finite State Machines. CoMo [19] is another well known network monitoring platform. We share with CoMo the (for us, side) idea of extensible plug-in metric modules, but besides this we are quite orthogonal to such work, as we rather focus on how to combine metrics with features and states using higher level programming techniques (versus CoMo’s low level queries).\n\nBro [27] provides a monitoring framework relying on event-based programming language for real time statistics and notification. Despite the attempt to define a versatile high level language, Bro is not designed to expose a clear and simple abstraction for monitoring application development and leave full programmability to its users (which we believe results in a more descriptive and yet more complex programming language).\n\nThe Real-Time Communications Monitoring (RTCMon) framework [15] permits development of monitoring applications, but again the development language is a low level one (C++), and (unlike us) any feature extraction and state handling must be dealt with inside the custom application logic developed by the programmer. CoralReef [21], FLAME [3] and Blockmon [18]\n\nare other frameworks which grant full programmability by permitting the monitoring application developers to “hook” their custom C/C++/Perl traffic analysis function to the platform. On a different line, a number of monitoring frameworks are based on suitable extensions of Data Stream Management Systems (DSMS). PaQueT [23], and more recently BackStreamDB [24], are programmable monitoring frameworks developed as an extension of the Borealis DSMS [2]. Ease of programming and high flexibility is provided by permitting users to define new traffic metrics by simply performing queries to the DSMS. The DSMS is configured through an XML file that is processed to obtain a C++ application code. Gigascope [10] is another stream database for network monitoring that provide an architecture programmable via SQL-like queries.\n\nOpensketch [34] is a recent work proposing an efficient generic data plane based on programmable metric sketches. If on the one hand we share with Opensketch the same measurement approach, on the other hand its data plane abstraction delegates any decision stage and logic adaptation the control plane and, with reference to our proposed abstraction, does not go beyond the functionalities of our proposed Measurement Subsystem. On the same line, ProgME [35] is a programmable measurement framework which revolves around the extended and more scalable notion of dynamic flowset composition, for which it provides a novel functional language.\n\nEven though equivalent dynamic tracking strategies might be deployed over Openflow based monitoring tools, by exploiting multiple tables, metadata and by delegating \"monitoring intelligence\" to external controllers, this approach would require to fully develop the specific application logic and to forward all packets to an external controller, (like in Openflow based monitoring tool Fresco [28]), which will increase complexity and affect performance.\n\nFinally, while our work is, to the best of our knowledge, the first which exploits eXtended Finite State Machines (XFSM) for programming custom monitoring logic, we acknowledge that the idea of using XFSM as programming language for networking purposes was proposed in a completely different field (wireless MAC protocols programmability) by [30].\n\n7\n\n## Conclusion\nThe StreaMon programmable monitoring framework described in this paper aims at making the deployment of monitoring applications as fast an easy as configuring a set of pre-established metrics and devising a state machine which orchestrates their operation while following the evolution of attacks and anomalies. Indeed, the major contribution of the paper is the design of a pragmatic application programming interface for developing stream-based monitoring tasks, which does not require programmers to access the monitoring device internals. Despite their simplicity, we believe that the wide range of features accounted in the proposed use cases suggest that StreaMon’s flexibility can be exploited to develop and deploy several real world applications.\n\n## 6.47 Gbps\nwhere pkt len and TX are the average packet length and replayed transmission bitrate respectively.\n\nAs expected, the throughput decreases with the number of metrics and grows with the number of cores (even though the growth is lower than expected due to the simple thread concurrency management adopted in this prototype). It is important to underline that such graph shows the worst metric computational scenario in which: (i) all metrics are sequentially updated and retrieved for each packet (single event and stateless logic) and are configured with both the VD (a BF pair) and the MV (DLEFT) enabled; (ii) all flow keys are different (n metrics, n * 2 flow keys). Nevertheless, the results are promising, as for example in case of 16 metrics, for which we observe the following average bitrate (Gbps):\n\n1 core\n\n2 cores\n\n3 cores\n\n6 cores\n\n0.566\n\n0.983\n\n1.367\n\n2.315\n\nFigure 12: System throughput evaluation\n\nWithout discussing here the advantages of a stateful pre-filtering (which will be shown in section 5.2.2), we want to underline that, in the typical case in which not all the metrics are updated for each packet and require distinct flow keys, we can experience a better relation between the processing throughput and the number of metrics. For this reason, we compared the average throughput obtained by executing the traffic classification algorithm described in [32] (the most computational demanding algorithm cited in 1, in terms of number of distinct metrics and flow keys, and portion of processed traffic). The following table shows the average bitrate (in Gbps) obtained by [32] in case of TCP traffic classification ( [32]: 6 metrics, 3 flowkeys) and the average bitrate of the worst case configuration (6 metrics and 12 flow keys).\n\n1 core\n\n2 cores\n\n3 cores\n\n[32]\n\n2.792\n\n4.316\n\n5.199\n\nworst case\n\n1.243\n\n2.812\n\n2.008\n\ncase\n\npkts.\n\nAVG plen [bytes]\n\nMs, FKs.\n\nTX [Gbps]\n\nRX [# core: Gbps]\n\n4.1\n\n7676958\n\n404.97\n\n8, 4\n\n3.658\n\n1: 1.956, 2: 2.954, 3: 3.654\n\n4.2\n\n11852112\n\n329.77\n\n4, 2\n\n2.462\n\n1: 2.462\n\n4.3\n\n9387240\n\n215.38\n\n2, 2\n\n2.067\n\n1: 2.003, 2: 2.067\n\nTable 3: Use case trace parameters and throughput\n\n5.2.2 Use case performance evaluation\n\nTable 3 shows the details of the test traces used for three among the use cases presented in Section 4 and the their performance evaluation, where pkt. no is the total number of packets, AVG plen is the average packet length, M is the total number of metrics, FK is that the transmission bitrate is fixed by the injector probe and depends on the average packet length.\n\nAs already underlined, the use case applications experience a better throughput with respect to the bitrate obtained with the same number of metrics in the worst case measurement showed in 12. Note that due to the different performances of the COMBO card processor and the limitation to single core processing 6 6\n\n6\n\nThis is due the fact that the COMBO card capture driver does not allow to open multiple instances of the same communication channel toward the FPGA NIC, the encrypted flow detection use case performance is omitted to avoid confusion, as it would present results not directly comparable with the remaining ones.\n\n5.2.3 FPGA accelerated primitives\n\nAs already discussed, our current StreaMon prototype supports seamless integration of HW precomputed primitives, and in particular we have implemented packet entropy computation (see section 4.4) and event parsing on a INVEA-TECH Combo FPGA card [1]. The interface between the Combo card and StreaMon core software is realized via a footer appended to the ethernet frame. The Combo card capture the packet traveling in the network under inspection, performs the required operation and transfer the resulting metrics and signals as a list of Type Len Value (TLV) to the PC hosting the capture card. This list of TLV is parsed by the Event Layer and will be available to the remaining layers.\n\nOur next step is to implement a full deep packet inspection module. To confirm its necessity, we have so far implemented a simplified content matching packet payload inspection primitive in both SW and HW. Figure 13 compares the two implementations for a toy example of just 32 content strings, showing the severe performance degradation of the SW implementation even in such small scale example. At the same time, the figure shows that, by offloading content matching primitives to the HW front-end, our prototype achieves almost optimal throughput performance.\n\nFigure 13: FPGA accelerated and SW string matching comparison\n\n6\n\n## Abstract\nThe fast evolving nature of modern cyber threats and network monitoring needs calls for new, “software-defined”, approaches to simplify and quicken programming and deployment of online (stream-based) traffic analysis functions. StreaMon is a carefully designed data-plane abstraction devised to scalably decouple the “programming logic” of a traffic analysis application (tracked states, features, anomaly conditions, etc.) from elementary primitives (counting and metering, matching, events generation, etc), efficiently pre-implemented in the probes, and used as common instruction set for supporting the desired logic. Multi-stage multi-step real-time tracking and detection algorithms are supported via the ability to deploy custom states, relevant state transitions, and associated monitoring actions and triggering conditions. Such a separation entails platform-independent, portable, online traffic analysis tasks written in a high level language, without requiring developers to access the monitoring device internals and program their custom monitoring logic via low level compiled languages (e.g., C, assembly, VHDL). We validate our design by developing a prototype and a set of simple (but functionally demanding) use-case applications and by testing them over real traffic traces."}]}
