What it detects

This rule detects the legitimate software protection service binary name sppsvc being executed from any location other than System32 which reflects the masquerading observed in this intrusion where the process ran from a hidden ProgramData directory. The genuine service only runs from System32 so execution elsewhere indicates a masqueraded malicious process.
