What it detects

This rule identifies PowerShell module activity that includes the command or reference text "get-smbshare" in either payload content or context information. Adversaries can use SMB share enumeration to discover accessible network folders and drives for subsequent collection and lateral movement planning. Telemetry relies on Windows PowerShell module logging fields that capture the module payload and contextual command text.
