Briefing

Lateral movement tools such as PsExec often install a temporary service on the target. You are reviewing the System log of APP-03 after an alert on certutil.

Event 7045 lists the service name, the file it runs, its start type, and the account. Real services point at an executable. A service whose file name is a shell command is a strong signal.
