Windows Cached Domain Credentials Reg Query
The following analytic identifies a process command line querying the CachedLogonsCount registry value in the Winlogon registry. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions and registry queries. Monitoring this activity is significant as it can indicate the use of post-exploitation tools like Winpeas, which gather information about login caching settings. If confirmed malicious, this activity could help attackers understand login caching configurations, potentially aiding in credential theft or lateral movement within the network.
