How Salt Typhoon & Volt Typhoon Forced a U.S. Critical Infrastructure Cybersecurity Rethink
Between 2021 and 2023, advanced Chinese threat actors known as Salt Typhoon and Volt Typhoon conducted highly covert cyber intrusions targeting U.S. telecommunications networks and critical infrastructure sectors. These groups utilized advanced tactics such as "living off the land," abusing legitimate administrative tools, and blending into east-west network traffic, making detection and remediation extremely challenging for defenders. Their primary objectives ranged from long-term espionage and persistent access to prepositioning for potential disruptive attacks in the event of geopolitical conflict. The hacks led federal agencies like the FBI and CISA to revise investigative methods, shifting to assume attackers may already be inside the network and forcing collaboration to uncover subtle anomalies rather than clear indicators. This incident is indicative of a broader industry trend: state-backed actors increasingly focus on stealth, cloud environments, and edge devices, targeting managed service providers and exploiting blind spots in monitoring. Their evolving tactics closely align with growing regulatory and CISO concern for stronger east-west visibility, zero trust controls, and continuous threat hunting across hybrid cloud infrastructure.
