HVNC Backdoor Mutex Creation Pattern (AppUpdateHelper/WinSvc)
Detects the creation of specific mutex objects ('AppUpdateHelper' or 'WinSvc') commonly associated with Hidden VNC (hVNC) backdoors. These mutexes are used by the malware to ensure only one instance is running on the host, and the regex pattern targets the specific naming convention (including a hex suffix) utilized by these threats.
