FBI declares suspected Chinese hack of US surveillance system a ‘major cyber incident’
The breach exposed surveillance returns and personal data on FBI investigations, and officials said the incident met the federal threshold for a major cyberattack.
- On April 1, the FBI declared a suspected Chinese cyberattack on its internal surveillance system a 'major incident' under the Federal Information Security Modernization Act , triggering mandatory congressional notification within seven days.
- Attackers bypassed the FBI's perimeter defenses on February 17, 2026, by 'exploiting the infrastructure of a commercial internet service provider vendor' using 'sophisticated techniques' to access an unclassified internal network.
- Hackers compromised the Digital Collection System Network , exposing pen register and trap-and-trace surveillance returns and personally identifiable information that reveals 'precisely who the bureau is watching' in active investigations.
- Formal declaration obligates the FBI to brief congressional oversight committees, produce a remediation plan, and submit to Office of Management and Budget scrutiny amid staff reductions and a proposed $500 million budget cut.
- Methods resemble Salt Typhoon, the Chinese state-linked group that breached nine major U.S. telecommunications companies in 2024; the investigation remains active with no formal attribution as of today, though experts call the designation rare.
