FBI, Verizon, AT&T, U.S. Treasury, Lumen and Windstream: FBI investigating hack on its wiretap and surveillance systems: Report

FBI Network Breach Targets Surveillance Systems

Hackers have reportedly compromised an FBI network used to manage wiretaps and foreign intelligence surveillance warrants, according to a CNN report citing an anonymous source. The breach was confirmed by an FBI spokesperson, who stated that the bureau detected and addressed "suspicious activities" on its systems, though no further details were provided.

The incident marks the latest in a string of high-profile cyberattacks on U.S. government agencies and corporations. Last year, Chinese hackers infiltrated the U.S. Treasury and the National Nuclear Security Administration, while Russian operatives stole sealed court records. Separately, a Chinese state-linked group, Salt Typhoon, breached at least 200 U.S. companies, including major telecommunications providers like AT&T, Verizon, Lumen, Charter Communications, and Windstream.

The FBI has not disclosed the extent of the breach or the identity of the attackers, but the incident underscores ongoing cybersecurity threats to critical U.S. infrastructure.
