UNC5976
UNC5976 is a Russia-linked espionage cluster reported by Google Threat Intelligence Group (GTIG) as part of broader Russian operations targeting battlefield technology, secure communications, and Ukrainian and allied defense assets. UNC5976 has conducted phishing campaigns delivering malicious RDP connection files, using drone-themed decoys and spoofing global defense firms. The malicious RDP files were configured to communicate with actor-controlled domains that mimicked a Ukrainian telecommunications company. The activity is positioned within sustained, multi-vector targeting of the defense industrial base (DIB) and Ukraine-related defense ecosystems.
