CISA, calling Volt Typhoon an urgent threat, updates DDoS response guide

US and international cybersecurity agencies have warned about the threat of Chinese state-sponsored cyber-actors targeting critical infrastructure. The advisory comes in response to increased use of “living off the land” attacks, where attackers use an organization’s own tools against it, and distributed denial of service (DDoS) attacks. Recommended defense strategies include proactive resourcing, robust logging measures, and treating cyber risk as a core business concern.
