Volt Typhoon's Silent Train network tied to Cisco SD-WAN zero-day exploitation
Lumen's Black Lotus Labs attributes a covert access network called Silent Train to the China-nexus group Volt Typhoon. It was first identified in late 2023 and was used for zero-day exploitation and strategic access, using rotating chains of compromised SOHO, IoT and enterprise devices. Cisco Talos linked malware that steals keys from Cisco SD-WAN to infrastructure overlapping with this network, which has since been disrupted.
