What it detects

This rule flags creation of a PowerShell module where ModuleContents are set to define the function Get-VMRemoteFXPhysicalVideoAdapter. Attackers can use module creation to influence how a signed binary or related component loads PowerShell content, enabling module load-order manipulation. The detection relies on PowerShell module creation telemetry that includes the embedded ModuleContents text.
