What it detects

This rule detects dllhost.exe running with a GUID/CLSID on its command line while not being parented by svchost.exe. Medusa ransomware leverages a COM elevation moniker so that dllhost hosts a malicious auto-approved COM object, and the abnormal parent process reveals the UAC bypass rather than legitimate COM surrogate activity.
