description: This rule identifies creation of a Windows service via Service Control Manager where the service name begins with "PAExec-" and the configured image path starts with "C:\WINDOWS\PAExec-". Attackers can use service installation to run code with elevated privileges and persist access on the host. It relies on Windows System logs for Service Control Manager event ID 7045 and matches the service provider name, service name prefix, and image path prefix.
