FBI Surveillance Network Breached: Salt Typhoon’s Quiet War on American Law Enforcement Infrastructure

Executive Summary: The FBI has classified a breach of its Digital Collection Systems Network as a “major incident” after attackers accessed wiretap returns, pen register data, and PII; the report links the compromise to Salt Typhoon (a China-linked APT) and places it within a multi-year campaign that previously exfiltrated call records from U.S. telecoms, highlighting third-party access risks, identity/Access management weaknesses, and significant counterintelligence implications.
