Sticky Key Like Backdoor Execution
Detects the usage and installation of a backdoor that uses an option to register a malicious debugger for built-in tools that are accessible in the login screen. This rule specifically looks for processes like cmd.exe or powershell.exe being launched by winlogon.exe, with command-line arguments indicating an attempt to leverage Windows accessibility features such as sethc.exe (Sticky Keys), utilman.exe (Utility Manager), osk.exe (On-Screen Keyboard), Magnify.exe, Narrator.exe, or DisplaySwitch.exe.
