status: test
description: Identifies execution of the TruffleSnout.exe binary via process creation events by matching the OriginalFileName and the image path ending in \TruffleSnout.exe. Attackers may use this tool for iterative Active Directory discovery and low-noise enumeration to build targeting context. The rule relies on Windows process creation telemetry with process image/path and OriginalFileName fields.
