What it detects

This rule detects schtasks creating an onlogon task at highest run level pointing at an executable in AppData Roaming, the persistence used by the Shadow Vector campaign delivering AsyncRAT through court-themed SVG decoys to Colombian users. Adversaries register a high-privilege logon task that relaunches their payload from a user-writable path. An onlogon highest task targeting Roaming is a strong persistence indicator.
