What it detects

This rule flags PowerShell script blocks that use WMI queries (Get-WmiObject/gwmi) targeting Win32_Service fields used for service path analysis. Attackers and testers use this to enumerate service properties such as Name, DisplayName, PathName, and StartMode to identify potentially exploitable unquoted service paths. Telemetry relies on PowerShell Script Block Logging capturing the query and selected field names in the script block text.
