status: test
description: This rule identifies Windows registry activity targeting the Run key entry containing 'ntkd' under the CurrentVersion\Run path. Attackers commonly use Run key modifications to establish persistence that launches automatically at user logon. The detection relies on registry event telemetry that includes the TargetObject field from Windows registry event logs.
