​​How Chinese Hackers Reached America’s Surveillance Infrastructure

Suspected Chinese state-linked hackers (attributed to Salt Typhoon/APT41) breached the FBI's DCS-3000 'Red Hook' segment — a technically unclassified but sensitive part of the Digital Collection System Network used to manage pen register and trap-and-trace surveillance — by exploiting a commercial ISP/vendor pathway; the intrusion exposed warrant records and communication metadata tied to investigations, was detected on 17 February 2026, and FBI response teams have investigated but have not publicly confirmed data exfiltration.
