Disabling Task Manager

splApache-2.0from splunk/security_content

The following analytic identifies modifications to the Windows registry that disable Task Manager. It leverages data from the Endpoint.Registry data model, specifically looking for changes to the registry path "*\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Policies\\System\\DisableTaskMgr" with a value of "0x00000001". This activity is significant as it is commonly associated with malware such as RATs, Trojans, and worms, which disable Task Manager to prevent users from terminating malicious processes. If confirmed malicious, this could allow attackers to maintain persistence and control over the infected system.
