What it detects

This rule detects the loading of profiler16.dll which was sideloaded through a renamed discord-rpc.x64.dll host binary in the WebDAV malware delivery campaign analyzed by Rapid7. Abusing a legitimately signed application to load an attacker-supplied DLL lets malicious code execute under the guise of a trusted process. Sightings of this DLL name loading into memory indicate active DLL search order hijacking.
