What it detects

This rule detects the Desktop Window Manager process dwm launching the shutdown utility which is an anomalous chain observed in an in the wild Windows local privilege escalation exploit that injected shellcode into dwm and invoked shutdown to trigger a DLL hijack against LogonUI. The genuine dwm process does not spawn shutdown so this relationship indicates exploitation.
