Volt Typhoon Used Compromised Office and IoT Devices for Cyber Espionage

State-sponsored threat group Volt Typhoon hijacked small office routers, IoT equipment, and enterprise systems to build a covert network for zero-day attacks. This infrastructure, dubbed Silent Train, allowed attackers to conceal their activities while targeting organisations for strategic access. Small and mid-sized businesses face real risks when perimeter hardware and smart devices are co-opted into these stealth operations.
