The FBI has formally classified a suspected Chinese intrusion into its Digital Collection System Network (DCSNet) as a “major incident” under the Federal Information Security Modernization Act (FISMA), triggering mandatory congressional notification. The breach targeted DCS-3000 — internally known as Red Hook — the bureau’s unclassified system for managing court-authorized wiretaps, pen registers, trap-and-trace collection, and FISA surveillance requests.

This is reportedly the first time the FBI has declared a major cyber incident since 2020.
