Winnti Malware HK University Campaign Process Creation
Detects specific process creation patterns associated with the Winnti malware campaign targeting Hong Kong universities in late 2019 and early 2020. The rule looks for suspicious parent-child process relationships and specific file paths used by the malware, such as executables under 'C:\Windows\Temp', 'C:\ProgramData\DRM', and 'C:\ProgramData\DRM\CLR'. It also identifies instances where legitimate applications like 'wmplayer.exe' or 'SearchFilterHost.exe' are launched from these suspicious directories or by suspicious parent processes.
