NGC5081 is a threat cluster first publicly identified in 2025 by F6 as one of several newly disclosed pro-state APT groups active against organizations in Russia and the CIS. Publicly available reporting in this context provides only a naming reference and does not include corroborated technical details on the cluster’s tooling, victimology, operational history, or distinctive tactics, techniques, and procedures. No widely established alias beyond the cluster name NGC5081 is confirmed here. Given the current lack of high-confidence public detail, NGC5081 is best described as a newly tracked espionage-oriented or state-aligned cluster of interest within the regional APT landscape, but its specific targets, malware, infrastructure patterns, and sub-group structure are not currently available.
