Description

The following analytic identifies a process command line used to enumerate DNS records. Adversaries, threat actors, or red teamers may employ this technique to gather information about a victim’s DNS, which can be utilized during targeting. This method was also observed as part of a tool used by the Sandworm APT group in a geopolitical cyber warfare attack. By using the dnscmd.exe Windows application, an attacker can enumerate DNS records for specific domains within the targeted network, potentially aiding in further attacks. This anomaly detection can serve as a valuable starting point for identifying users and hostnames that may be compromised or targeted by adversaries seeking to collect data information.
