APT37 Operation Artemis Sysinternals DLL Side Loading

Detects a specific DLL side-loading pattern used by APT37 in the 'Operation Artemis' campaign. A legitimate Sysinternals utility (e.g., 'mhelp.exe', 'vhelp.exe', 'Volumeid1.exe') is executed from a suspicious directory and loads a malicious 'version.dll' from the same path.
