What it detects

This rule detects use of attrib.exe to set both the hidden and system attributes on a file. The multi-stage infection chains hide their dropped startup scripts and payloads from casual inspection using this technique. Applying the hidden and system flags together is a common defense evasion move to conceal malicious artifacts.
