What it detects

This rule flags process creation command lines containing the AtomicTestHarnesses function name Invoke-ATHRemoteFXvGPUDisablementCommand (or its truncated variant). The command is associated with abusing RemoteFXvGPUDisablement.exe to execute custom PowerShell via module load-order hijacking. Telemetry relies on Windows process creation events and the exact command-line text used to invoke the harness function.
