What it detects

This rule detects the attrib command setting hidden and system attributes on files, a concealment technique observed in the Suky Castle campaign where the chain applied attrib to hide dropped artifacts before scheduling persistence. It captures the marking of files as hidden and system to keep malicious payloads out of view. Detecting this is important because interactive use of attrib to apply both hidden and system flags is uncommon and frequently tied to staging of malware.
