What it detects

This rule detects HUI Loader side-loading, where the legitimate signed McAfee binary mfeann.exe loads an attacker-supplied LockDown.dll. This pairing was used against the Asian gambling sector to run encrypted payloads under a trusted process. The DLL name loaded by this specific host executable is a strong side-loading indicator.
