UAC-0200
UAC-0200 is a Russian-attributed threat cluster that has been linked to cyber-espionage activity targeting Ukraine, including Ukrainian defense and military-related Windows systems. CERT-UA reported increased cyber-espionage activity against Ukraine involving UAC-0200, and broader reporting identified UAC-0200 as one of five Russian-attributed groups responsible for much of the activity against Ukrainian forces. The cluster has been associated with social-engineering campaigns that abuse messaging applications, particularly Signal, to deliver the DarkCrystal RAT (DCRat) remote access trojan. CERT-UA warned that attackers used compromised accounts and messenger-based lures to persuade victims to open malicious files on their computers. Reporting also states that DCRat, also known as Dark Crystal RAT, was created by a Russian developer and has previously been used against Ukraine by UAC-0200. Based on the provided content, UAC-0200 uses remote access trojans to compromise victim systems, with DCRat specifically associated with this cluster. The content links the group to espionage-oriented operations against Ukraine and to the broader Russian campaign focus on intelligence collection against Ukrainian military and defense targets. Known alias in the provided material: UAC-0200.
