What it detects

This rule detects modification of the Svchost netsvcs registry value, abused by the SADBRIDGE loader to register a malicious service that is hosted by svchost.exe and delivers the GOSAR backdoor. Adding an entry to the netsvcs service group lets the attacker run code inside a trusted host process for stealthy persistence. Changes to this value outside of software installation warrant investigation.
