What it detects

This rule detects PowerShell running the whatpc.ps1 script with an execution policy bypass and a hidden window, matching the UAT-8302 reconnaissance stager. The named script drives host profiling and follow-on tasking while the hidden bypass flags suppress user visibility and controls. Execution of this specific script under these flags indicates active UAT-8302 operations.
