What it detects

This rule detects modification of the per-user Folder shell open command class key used to hijack the auto-elevating sdclt.exe. Warzone RAT writes its payload path into HKCU Software Classes Folder shell open command so that launching sdclt runs the malware with elevated privileges and bypasses UAC. Changes to this class command key are strongly associated with UAC bypass techniques.
