What it detects

This rule identifies registry changes where a Windows service’s ImagePath is set to a location within ProgramData or AppData-style user-controlled directories. Such paths can support staging, persistence, or privilege escalation if an attacker can influence or replace the referenced binaries. It relies on Windows registry set telemetry for TargetObject and Details fields containing ControlSet service ImagePath values pointing into those directories, while excluding several known benign services and well-known Defender/Zoom/MBAM installer patterns.
