description: The following analytic detects registry modifications that disable the Control Panel on Windows systems. It leverages data from the Endpoint.Registry data model, specifically monitoring changes to the registry path "*\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer\\NoControlPanel" with a value of "0x00000001". This activity is significant as it is commonly used by malware to prevent users from accessing the Control Panel, thereby hindering the removal of malicious artifacts and persistence mechanisms. If confirmed malicious, this could allow attackers to maintain control over the infected machine and prevent remediation efforts.

how_to_implement: To successfully implement this search, you need to be ingesting logs with the registry value name, registry path, and registry value data from your endpoints. If you are using Sysmon, you must have at least version 2.0 of the official Sysmon TA. https://splunkbase.splunk.com/app/5709
