FBI and CISA Warn of Extensive Chinese Cyber-Espionage on US Telecoms

The FBI and CISA have identified a significant cyber espionage campaign by the People's Republic of China targeting U.S. telecommunications infrastructure. PRC-affiliated actors have compromised networks at multiple telecom companies, stealing customer call records and private communications, particularly of individuals involved in government or political activities. The agencies are providing technical assistance and sharing information to help potential victims and strengthen cyber defenses. Organizations suspecting they are affected are urged to contact their local FBI field office or CISA.
