What it detects

This rule detects creation of a scheduled task named ChromeUpdate or EdgeUpdate whose action runs regsvr32, the persistence behavior of the Kimsuky HttpSpy variant that reloads its disguised loader on a one minute interval. Adversaries leverage browser update task names to blend with legitimate maintenance while ensuring the loader restarts, making early detection critical for surfacing persistence before remote command execution.
