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.

Detects a Parallels appliance tar archive containing a directory entry name with an embedded double-quote character followed by the --use-compress-program flag, characteristic of the ParaShells (CVE-2026-90894) tar argument-injection payload
Detects the 'prl_disp_service' process spawning 'tar' with the '--use-compress-program' flag set to an unconventional binary. This behavior is associated with the exploitation of ParaShells (CVE-2026-90894), where an attacker leverages the compression program hook in 'tar' to execute arbitrary commands with root privileges.
Detects instances where the NW.js (Node-Webkit) framework binaries (nw.exe, node.exe) spawn common command-line interpreters or script-hosting utilities (e.g., cmd.exe, powershell.exe, wscript.exe) while executing associated application files like main.js or nw.pak. This behavior is indicative of potential exploitation of a browser-based application to gain shell access or execute arbitrary code on the host system.

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.
Detects the use of living-off-the-land binaries such as mshta.exe, wmic.exe, and rundll32.exe to execute commands or code indirectly. This technique is often used to bypass security restrictions that might prevent the direct execution of common command-line interpreters.
Detects instances where the NW.js (Node-Webkit) framework binaries (nw.exe, node.exe) spawn common command-line interpreters or script-hosting utilities (e.g., cmd.exe, powershell.exe, wscript.exe) while executing associated application files like main.js or nw.pak.

This behavior is indicative of potential exploitation of a browser-based application to gain shell access or execute arbitrary code on the host system.
This rule detects the execution of arbitrary commands via the Windows Subsystem for Linux (WSL) by monitoring process creation events where 'wsl.exe' is the executable. It specifically looks for command lines that include flags like '--exec' or '-e', or common shell commands and downloaders such as 'curl', 'wget', 'bash -c', 'sh -c', 'nc ', or 'ncat '. This activity can indicate an adversary leveraging WSL to execute malicious code or bypass security controls.

This behavior is indicative of potential exploitation of a browser-based application to gain shell access or execute arbitrary code on the host system.
This rule detects a specific and highly suspicious process lineage: pcalua.exe (Program Compatibility Assistant) spawning powershell.exe, which subsequently triggers WmiPrvSE.exe, followed by cmd.exe and finally rundll32.exe. This chain often indicates a sophisticated attempt to bypass security controls by nesting execution through legitimate Windows utilities.
Detects executables launched by common LOLBins (msiexec, powershell, cmd, wscript, cscript, regsvr32, rundll32)
that are either signed by a non-Microsoft/non-trusted-third-party publisher, or entirely unsigned.
that are either signed by a non-Microsoft/non-trusted-third-party publisher, or entirely unsigned.
This rule detects potentially malicious child processes spawned by LOLBins (Living Off the Land Binaries) like mshta.exe, wscript.exe, cscript.exe, rundll32.exe, or regsvr32.exe, which were themselves initiated by document applications (e.g., Office, Acrobat) or common shell interpreters. It specifically identifies downstream payloads that are either unsigned or signed by non-trusted publishers, filtering out Microsoft and common third-party software signers.
This query hunts for suspicious cases where Warp Terminal or a Warp-related parent process spawns Unix-like shell interpreters such as sh, bash, zsh, fish, or dash, and executes commands using shell execution patterns like -c, /bin/sh, sh -c, or bash -c. It detects suspicious post-condition behavior consistent with exploitation attempts for CVE-2026-48703 and CVE-2026-48731
Detects the Starland RAT's self-deletion routine, which invokes os.remove(script_path) followed by sys.exit() when the C2 responds with an HTTP 403 kill-switch. The deleted file path matches the executing Python interpreter's own script/image path, indicating classic self-delete behavior.
