The threat group ShinyHunters has adopted a new tactic of subdomain impersonation for initial access, moving away from newly registered lookalike domains. They are utilizing mobile-first lures and outsourcing spam services to scale their operations. The group is likely reusing previously stolen CRM and ERP data to drive social engineering attacks. Their approach involves phone-guided adversary-in-the-middle phishing to capture credentials and authenticated sessions. ShinyHunters is also scaling vishing operations through paid contractors and specialized harassment services. This evolution in tactics allows for rapid identity-to-SaaS compromise without deploying malware, making traditional domain-based monitoring less effective.

This analysis examines a series of coordinated SaaS account compromises across multiple customer environments, involving suspicious logins from VPS-linked infrastructure followed by unauthorized inbox rule creation and deletion of phishing-related emails. The attackers leveraged virtual private servers (VPS) from providers like Hyonix to bypass geolocation-based defenses, evade IP reputation checks, and blend into legitimate traffic. Key tactics included session hijacking, inbox rule manipulation, and attempts to modify account recovery settings. The incidents highlight the growing abuse of VPS infrastructure in stealthy, scalable attacks targeting SaaS platforms.
