Uncommon Userinit Child Process

Detects uncommon "userinit.exe" child processes, which could be a sign of uncommon shells or login scripts used for persistence.

Detection logic

The rule states no platform. This is derived from the ATT&CK technique it maps to.
Log source product: windows

Legitimate logon scripts or custom shells may trigger false positives. Apply additional filters accordingly.
