Detects PavokwiLoader behavior where a potentially malicious process spawns a browser or system process (e.g., smartscreen.exe) in a suspended state, followed by cross-process memory allocation and writing, and subsequent thread hijacking or execution resumption, indicating a process hollowing injection technique.

This rule detects modifications to Group Policy Objects (GPOs) that are either explicitly marked as malicious based on known indicators (GUIDs or 'PAYLOAD' strings) or involve unauthorized modifications to domain-root or organizational unit GPO links. It monitors Active Directory security event logs for object changes.

Detects the creation of multiple suspicious scheduled tasks using schtasks.exe initiated by scripting engines (wscript.exe, cscript.exe). The rule filters for specific task names associated with known malicious patterns and XML definition files located in a specific directory path, identifying potential automated persistence or malware installation behavior.

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.
Detects network communication with known malicious domains and IP addresses, as well as the presence of known malicious file hashes on the system. The rule correlates network connection events, file creation events, and process creation events against predefined lists of C2 infrastructure and malware indicators.
Detects spoofed emails carrying a .patch attachment sent to a GitLab incoming-email merge-request address. Requires Microsoft's composite authentication verdict (CompAuth: fail) -- a lower-noise spoofing signal than raw SPF/DKIM/DMARC -- and excludes sender/recipient pairs already seen corresponding with that token address in the prior 30 days to suppress recurring legitimate contributors.
