Description
The following analytic identifies the execution of adfind.exe with specific command-line arguments related to Active Directory queries. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names, command-line arguments, and parent processes. This activity is significant because adfind.exe is a powerful tool often used by threat actors like Wizard Spider and FIN6 to gather sensitive AD information. If confirmed malicious, this activity could allow attackers to map the AD environment, facilitating further attacks such as privilege escalation or lateral movement.
