Sable Squirrel operates a massive criminal enterprise controlling over 10,000 domains, spending an estimated $7 million acquiring expired domains to inherit their reputation and traffic. The actor runs illegal Asian sports streaming services under brands like Xoilac, Cakhia, and 90phut, which funnel viewers to gambling platforms including VSBet and 8xbet. Analysis reveals over 31,000 malware samples connecting to Sable Squirrel infrastructure, including Quasar RAT, AsyncRAT, DCRat, and ransomware variants, with the same domains simultaneously hosting streaming content and serving as command-and-control servers. Despite Vietnamese law enforcement actions in early 2026, including arrests and asset seizures, the operation quickly recovered and expanded for the World Cup, demonstrating resilience through domain rotation and shared technical infrastructure spanning multiple Asian markets.
An analysis of Chinese hosting environments identified over 18,000 active malware command-and-control (C2) servers distributed across 48 infrastructure providers, with China Unicom hosting nearly half. The majority of malicious activity is C2 infrastructure (84%), followed by phishing (13%). Key malware families such as Mozi, ARL, and Cobalt Strike dominate C2 activity, supporting both cybercrime and state-linked operations. High-trust networks like China169 Backbone and CERNET are exploited, revealing persistent abuse patterns and infrastructure reuse across campaigns.
