A service was installed in the system
A service was installed in the system. Logs the service name, service file name (binary path), and service start type.
Event ID 4697 is generated when a new Windows service is registered in the Service Control Manager (`services.exe`). Attackers and commercial C2 frameworks (e.g., Cobalt Strike, Metasploit, PsExec) routinely install temporary or persistent background services to execute elevated payloads (`SYSTEM` privileges) and maintain system persistence across reboots.
Failure Reason / Root Cause:
Standard software installation, IT remote administration tools (e.g., PsExec), or attacker persistence and lateral movement service creation.

Recommended actions
- Inspect the `Service File Name` (binary path) for execution out of unusual directories (`C:\Windows\Temp\`, `C:\Users\Public\`, `C:\ProgramData\`).
- Look for random alphanumeric service names or service paths containing encoded PowerShell/cmd commands.
- Compare newly installed services against baseline software inventories across the enterprise fleet.
