China-nexus cyber actors have strategically shifted to utilizing large-scale covert networks of compromised SOHO and IoT devices to obfuscate their operations. These dynamic botnets, such as Raptor Train and KV Botnet, facilitate deniable access and complicate traditional static IOC-based defense, requiring organizations to adopt behavioral baselining and dynamic threat intelligence.
China-nexus threat actors are increasingly utilizing large-scale covert networks of compromised SOHO routers and IoT devices to obfuscate their operations and route malicious traffic. This strategic shift renders traditional static IOC blocklists ineffective, requiring defenders to adopt behavioral profiling, zero trust principles, and active network hunting to detect multi-hop proxy traffic.
Russian military intelligence actor Forest Blizzard is compromising vulnerable SOHO routers to alter DNS settings and hijack network traffic. This compromised infrastructure is subsequently used to conduct selective Adversary-in-the-Middle (AiTM) attacks, intercepting TLS connections to steal credentials and sensitive data from targeted organizations.
Russian state-sponsored threat actor APT28 is exploiting vulnerable SOHO routers to modify DHCP and DNS settings, redirecting user traffic to malicious infrastructure. This DNS hijacking facilitates Adversary-in-the-Middle (AitM) attacks designed to harvest credentials and OAuth tokens for web and email services.
