Volt Typhoon's 'Silent Train' framework exposed: ephemeral botnet hits critical infrastructure

Researchers have detailed Volt Typhoon's 'Silent Train' framework, which uses rapidly rotating compromised devices to infiltrate hundreds of critical infrastructure networks. The technique evades detection by cycling through ephemeral nodes, marking a notable evolution in the group's tradecraft. The full scope of compromised networks remains unclear, but the targeting of critical infrastructure signals sustained espionage risk.
