Lazarus PerfhLoader Persistence via SessionEnv Service Modification
Detects the PerfhLoader persistence technique used by the Lazarus Group, which involves modifying the 'SessionEnv' service to start automatically and either adding sensitive privileges or dropping a malicious DLL for phantom loading. This rule correlates events across process launches (sc.exe modifying SessionEnv service), registry modifications (adding privileges to SessionEnv service), and file creations (dropping a specific DLL for phantom loading).
