Detects attempts to modify, disable, or exclude paths and processes from Microsoft Defender Antivirus using legitimate administrative utilities such as PowerShell, cmd, sc, and netsh. This behavior is indicative of an adversary attempting to evade security monitoring.
This rule detects potential reflective code injection or in-memory loading (fileless) where a DLL or PE image is loaded by mshta.exe or powershell.exe, but the module load event lacks a valid file path on disk (or indicates a device path). This behavior is often associated with the execution of malicious payloads such as the Amatera loader, where payloads are executed directly in memory to evade file-based security detections.

Detects Node.js or related helper processes executing shell commands (cmd.exe, powershell.exe) or other processes where the execution involves the 'withCreateProcessUser' argument. This often indicates attempts to bypass execution restrictions or run malicious payloads by utilizing Node.js as an execution proxy within unconventional or temporary directories.
This rule detects potentially malicious PowerShell execution patterns involving hidden windows, administrative elevation via 'Start-Process -Verb RunAs', and the targeting or execution of rsetup64.exe within specific system paths. It also flags execution chains where 'net session' commands, often used for discovery or local privilege verification, are piped to null and followed by or initiate the same target executables, suggesting lateral movement or persistence attempts.
This rule detects potential remote command execution using Windows Management Instrumentation (WMI) via wmic.exe or PowerShell, as well as suspicious child processes spawned by the WMI provider host (wmiprvse.exe). It monitors for command lines utilizing the /node switch to target remote systems or invoking WMI methods to trigger execution, which are common patterns for lateral movement.
Detects instances where the Windows Management Instrumentation service (wmiprvse.exe) launches suspicious command-line interfaces or interpreters (PowerShell, CMD, cscript, etc.), or executes scripts from sensitive/temporary directories. The rule includes exclusions for common management tools to reduce noise.
Detects the execution of 'charmap.exe' from the Syswow64 directory where the process hierarchy indicates suspicious activity. The detection identifies a chain where PowerShell spawns 'conhost.exe', which in turn spawns a process from a temporary directory (interpreted as a renamed AutoIT executable) that then launches 'charmap.exe'. This pattern is indicative of a multi-stage obfuscated execution flow often used in malware dropper scenarios to bypass standard monitoring.
Detects the execution of PowerShell or PWSH with command-line arguments often used to obfuscate scripts or hide activity, such as encoded commands (-enc), base64 decoding, or running the process with a hidden window.
Detects instances where the Windows Management Instrumentation service (wmiprvse.exe) launches suspicious command-line interfaces or interpreters (PowerShell, CMD, cscript, etc.), or executes scripts from sensitive/temporary directories. The rule includes exclusions for common management tools to reduce noise.

Detects uncommon or suspicious child processes spawning from a WSL process. This could indicate an attempt to evade parent/child relationship detections or persistence attempts via cron using WSL.

This rule detects attempts to disable, terminate, or misconfigure security software, including antivirus, EDR, and endpoint protection solutions, by monitoring the execution of system administration binaries (such as taskkill, net, sc, wmic, powershell) with command-line arguments indicating service or process stopping, deletion, or configuration changes related to security-specific product names.
Detects artifacts of the winAgent v2.0 Windows implant line, including mod_* modules, WUEngine persistence binaries, and COM/CLSID hijack strings used by AI-assisted implant development
