What it detects

This rule flags PowerShell classic module creation when the created module content contains a function definition for Get-VMRemoteFXPhysicalVideoAdapter. Attackers can use signed or pre-existing binaries with hijacked module loading behavior to execute malicious code in trusted contexts. The detection relies on PowerShell telemetry capturing the module contents text during module creation.
