What it detects

This rule identifies Windows services created with service binary paths or filenames containing 'powershell' or 'pwsh' using Security audit Event ID 4697. Attackers may use PowerShell to run arbitrary code persistently under the Windows Service control, blending into legitimate service activity. It relies on Security log telemetry for service installation events and matches on the service file name content.
