Detects the execution of base64 encoded PowerShell commands initiated by conhost.exe with the --headless flag. The decoded command contains specific suspicious patterns, including accessing environment variables, reading file content, and deleting files, which is characteristic of malicious scripts attempting to stealthily interact with the environment.
This rule detects processes attempting to interact with the Docker daemon via its Unix domain socket (/var/run/docker.sock). This is a common technique used by attackers to escape from a container, gain host-level control, or execute arbitrary container administration commands.
This rule detects the execution of Mimikatz or the use of its common command-line arguments, which are indicative of credential dumping and post-exploitation activities. It monitors process creation events for the 'mimikatz.exe' binary or command-line patterns associated with credential theft techniques such as dumping LSASS memory, extracting passwords, or Kerberos ticket manipulation.
Detects the execution of the Rubeus tool, a widely used offensive security tool for Kerberos manipulation, including ticket requests, pass-the-ticket, and credential dumping.
Detects usage of the Android Debug Bridge (ADB) 'pair' command initiated by processes other than known legitimate Android development tools (e.g., adb.exe, Android Studio). This may indicate an attacker attempting to wirelessly pair a malicious device or gain unauthorized access to an Android device over the network.
This rule detects a specific persistence technique used by AvisLoader malware. It monitors for the creation of a .lnk.backup file alongside a corresponding .lnk shortcut modification in common shell locations (Desktop, Taskbar, etc.), coupled with the execution of wscript.exe or cscript.exe referencing the 'VLCAssistant' VBScript within a short time window. This sequence indicates an attempt to persist malicious activity by backing up existing shortcuts and replacing them with a launcher for the AvisLoader payload.

Detects execution of auto.exe (associated with AvisLoader) combined with a specific registry-based UAC bypass technique using the ICMLuaUtil COM elevation moniker (CLSID 3E5FC7F9-9A51-4367-9063-A120244FBEC7). This pattern is characteristic of UACME method 41 to achieve privilege escalation.

Detects instances of ImageMagick binaries (convert, identify, magick) spawning suspicious child processes (e.g., shells, network tools, scripting interpreters) when processing image files with HEIF/HEIC extensions. This is a common pattern for exploiting image processing vulnerabilities (e.g., ImageTragick) to achieve remote code execution.
Detects the execution of LNK files that use a double extension (e.g., .pdf.lnk) to masquerade as PDF documents. This behavior is indicative of spear-phishing campaigns where malicious shortcuts are delivered via ZIP archives to execute hidden PowerShell commands for secondary stage downloader or persistence mechanisms.
Detects the execution of VelvetCake modular scripts by PowerShell, which involves downloading and executing scripts from %TEMP% via Invoke-Expression, and monitoring the C:\Users\Public directory for file staging and subsequent exfiltration. This rule captures the tactical loop of script execution, output file creation, and exfiltration preparation often observed in Operation Conflict Compass activity.
Detects malicious PowerShell scripts that perform a sequence of reconnaissance activities, including security product enumeration via WMI (SecurityCenter2), system configuration discovery (ipconfig, systeminfo), process enumeration, recent file access, and drive mapping. This behavior is indicative of second-stage reconnaissance by threat actors to map the target environment.
Detects unexpected child process execution spawned by the ScreenConnect ClientService. This activity is indicative of the exploitation of CVE-2026-84869, which allows for unauthorized file transfer and arbitrary code execution within the context of the remote support agent without requiring user interaction or confirmation.
Detects the execution of the Android system utility 'getevent' by suspicious processes or in contexts suggesting unauthorized input event monitoring. This may indicate an attempt to capture user input, touch events, or screen interaction data.
Detects the execution of a process named 'msedge.exe' from the 'ProgramData\Microsoft\Windows\Telemetry' directory. Legitimate Microsoft Edge executables do not run from this location, suggesting an attempt to masquerade as the legitimate browser to bypass security controls or evade detection.
This rule detects modifications to Microsoft Defender antivirus exclusions. Adversaries often add paths or files to the exclusion list to prevent the detection of malicious tools or staging folders during cyberattacks. The rule monitors both command-line execution of PowerShell (Add-MpPreference/Set-MpPreference) and direct registry modifications related to Windows Defender paths.
Detects execution of potential MovieReaper loader components by monitoring for the creation of a specific, statically defined global mutex or patterns indicative of dynamic mutex naming conventions often used to ensure single-instance execution by malware.
Detects the use of PowerShell with the EncodedCommand parameter to modify or create entries in the HKEY_CURRENT_USER Run registry keys, a technique used by the HEAVYGRAM malware for persistence.
Detects the use of the Add-MpPreference cmdlet with -ExclusionPath, or processes spawned by CRUDEEXCLUDE.exe, which are associated with configuring Microsoft Defender exclusion paths. This is often used by adversaries to evade detection by excluding malicious files or directories from antivirus scanning.
