SOHO Router Compromise Drives DNS Hijacking and AiTM
🔒 Since at least August 2025, Microsoft Threat Intelligence reports that the Russian military-linked actor Forest Blizzard (and sub-group Storm-2754) has been exploiting insecure SOHO routers to reroute DNS queries to actor-controlled resolvers. The actor appears to use the legitimate dnsmasq service on thousands of devices to capture DNS traffic and, selectively, perform TLS adversary-in-the-middle (AiTM) attacks against Microsoft Outlook on the web and targeted government services. Microsoft identified over 200 affected organizations and more than 5,000 consumer devices and published mitigation, detection, and hunting guidance.
