UAC-0173 is a threat actor tracked for malware campaigns targeting Ukrainian organizations. Public reporting links the group to the use of AsyncRAT in Windows-focused intrusions. Observed tradecraft includes anti-analysis and defense-evasion behavior such as virtualization or sandbox checks via WMI, enumeration of installed antivirus products, termination of security and analysis processes, administrative privilege checks, and tampering with the Antimalware Scan Interface to reduce detection by Microsoft Defender and related security tooling. Reported samples associated with the actor have been written in .NET. Based on the available evidence, UAC-0173 is best characterized as a malware operator focused on Ukrainian targets, with demonstrated capabilities in reconnaissance of host defenses, post-compromise evasion, and interference with defensive controls.
