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.

The US Department of Justice and Microsoft disrupted LummaC2 infostealing-malware through domain seizures, taking down over 2,300 associated domains. The FBI and CISA released an advisory detailing LummaC2's tactics and indicators of compromise, including 114 domains. Analysis of these domains revealed common registration patterns, such as using Eastern European names and specific mail server hostnames. Notably, several domains featured an 'About Cats' landing page, with 58 additional domains sharing this characteristic and having high risk scores. These domains are suspected of distributing LummaC2 and other malware strains. Despite the takedown efforts, 41 of these domains remain active, highlighting the need for continued vigilance against LummaC2 infrastructure.
