This analysis examines infrastructure used by multiple Russian cyber espionage clusters targeting individuals in academia, think tanks, and organizations across Europe and the United States. The investigation expands on three threat clusters (UNC6293, UNC7005, and UNC5976) that employed OAuth phishing, Microsoft device code phishing, and WhatsApp targeting. UNC6293 utilized lure domains impersonating the Council on Foreign Relations and government portals, with possible Evilginx configurations. UNC7005 demonstrated lower sophistication with poor operational security, using domains like my-invite[.]org for phishing campaigns. UNC5976 employed Google Drive impersonation domains for OAuth phishing. The analysis leverages historical DNS data, CSS hash similarities, favicon analysis, registration patterns, and certificate information to identify additional infrastructure and tracking methods for discovering related malicious domains and IP addresses.

Three distinct suspected Russian cyber espionage threat clusters—UNC6293, UNC7005, and UNC5976—are abusing legitimate authentication flows to target individuals in academia, aerospace, defense, governments, and think tanks across Europe and the United States. These groups conduct sophisticated phishing campaigns using app password phishing, OAuth phishing, device code phishing, and malware deployment. UNC6293 and UNC7005 are assessed with moderate confidence to be initial access clusters linked to ICE RELIC (formerly APT29), while UNC5976 appears distinct. Operations leverage social engineering through fake diplomatic invitations, conference registrations, and file sharing pages. UNC7005 was tied to hospitality captive portal redirects and deployed MaaS infostealers including VIDAR and ATOMIC. These actors abuse legitimate authentication mechanisms including Google OAuth, Microsoft device codes, and WhatsApp device linking to compromise personal accounts, making detection challenging for organizations.

Recent investigations have uncovered sophisticated phishing campaigns employing multi-stage redirection chains that abuse trusted cloud infrastructure and newly registered domains. One campaign exploits Framer, a no-code web platform, combined with Cloudflare Workers to host deceptive landing pages. These pages utilize HTML redirection smuggling via the Blob API, Web Crypto API for decryption, and anti-debugging techniques to evade detection. Another campaign involves device code phishing targeting OneDrive credentials through three-stage redirections using newly registered domains with randomized alphanumeric strings. Both campaigns employ brand impersonation, custom CAPTCHA challenges, and anti-analysis measures including keyboard shortcut blocking. The threat actors leverage a hybrid infrastructure combining legitimate cloud services with short-lived domains to bypass traditional detection methods.
