UNC5976 is a suspected Russian cyber-espionage cluster assessed with high confidence to have a Russian nexus. It is operationally distinct from UNC6293 and UNC7005 and primarily targets military, aerospace, defense-industrial-base, and NGO or think-tank entities, with a particular focus on Ukraine and Armenia. The cluster conducts phishing operations using file-sharing and cloud-service impersonation to induce victims to authenticate through legitimate Google OAuth flows and authorize attacker-controlled cloud projects. This enables automated collection of authentication tokens and can provide persistent access to victim accounts without requiring repeated multifactor-authentication prompts. UNC5976 has used dedicated infrastructure for post-compromise activity and has shifted portions of its phishing hosting away from Google infrastructure following disruption efforts. The group has also deployed the malicious Excel add-in HEADRUSH, which leads to an HTML Application downloader, in activity associated with Ukrainian aerospace targeting. Additional observed activity includes phishing using malicious RDP connection files and drone-themed decoys impersonating defense organizations.
