"The FBI just classified the breach of its wiretap surveillance network as a FISMA major incident. The system is the Digital Collection System Network, which stores court-authorized wiretap returns, pen register metadata, FISA warrant data, and personally identifiable information on active FBI investigation targets."
"The attackers got in through a vendor ISP that connects to the FBI's network, not through the FBI's own defenses. The Wall Street Journal reports that investigators suspect Chinese government-affiliated hackers."
"This is the same playbook. Salt Typhoon compromised lawful intercept systems at AT&T and Verizon in 2024 by exploiting the telecom infrastructure that CALEA requires carriers to maintain for government surveillance."
"Nobody mandated that the capability be secured against adversaries. Senator Wyden proposed legislation to fix that after."
The FBI has classified a breach of its Digital Collection System Network as a major incident under FISMA. This system contains sensitive data, including wiretap returns and personally identifiable information related to ongoing investigations. The breach occurred through a vendor ISP, not the FBI's own defenses, and is suspected to involve Chinese government-affiliated hackers. This incident mirrors previous attacks on telecom systems, highlighting vulnerabilities in the infrastructure required for government surveillance, which lacks mandated security measures against adversaries.
