Summary

The FBI and CISA have uncovered an extensive Chinese cyberespionage campaign targeting U.S. telecommunications networks.

Hackers linked to Beijing accessed call records and intercepted communications of individuals in government and political spheres, attempting to infiltrate surveillance programs governed by the Foreign Intelligence Surveillance Act (FISA).

This follows recent Chinese cyber operations, including a botnet scheme and alleged phone hacks targeting high-profile U.S. figures.

In response, U.S. agencies and the telecom industry are strengthening defenses.
