This detection rule is designed to identify attempts by adversaries to disable or delete important scheduled tasks within a Windows environment, which can lead to data destruction and hinder system recovery capabilities. Scheduled tasks are crucial for executing processes on a predetermined basis, and the removal or modification of these tasks often indicates malicious intent. The rule monitors specific Event IDs, namely 4699 and 4701, which correspond to actions related to scheduled tasks. Additionally, it focuses on specific critical tasks associated with system restore, Windows Defender, BitLocker, and other important system tasks. The detection conditions require that the selected events occur along with certain filters that help eliminate benign instances, specifically targeting the deletion or disabling of tasks that are critical for system integrity by checking for specific task names and user account endings.
