What it detects

This rule detects creation of a scheduled task named SystemSoundsService2 through schtasks.exe, a masquerading name GoldenJackal uses to persist its air-gap tooling on government systems. The name imitates a legitimate Windows sounds service to blend in. This indicates scheduled-task persistence by an espionage actor.
