description: This rule flags Windows Code Integrity operational events where a revoked signed image is loaded into the system. Such activity matters because loading revoked binaries can indicate policy bypasses, tampering, or debug-assisted exceptions that allow untrusted code to execute. It relies on Code Integrity operational telemetry capturing EventID 3032 (revoked image loaded) and EventID 3035 (revoked image loaded while a kernel mode debugger is attached).
