A new report from the Wall Street Journal reveals that a Chinese hacking campaign has compromised more U.S. telecommunications companies than initially believed. The hackers reportedly targeted major providers, including Charter Communications, Consolidated Communications, and Windstream, alongside previously known targets like AT&T, Verizon, Lumen Technologies, and T-Mobile.
The hackers exploited vulnerabilities in unpatched network devices from Fortinet and large routers from Cisco Systems, enabling deep intrusions into critical infrastructure. According to U.S. officials, these breaches could allow the hackers to disrupt ports, power grids, and other essential services.
National Security Adviser Jake Sullivan reportedly briefed telecom and tech executives at a secret White House meeting in late 2023, warning that Chinese hackers had gained the capability to shut down dozens of critical infrastructure systems at will.
Telecom companies say they’ve taken steps to secure their networks. Verizon and T-Mobile confirmed that some government and political figures were targeted, but they’ve since contained the breaches. However, concerns remain over the scope of Chinese cyber-espionage operations.
China has denied the allegations, accusing the U.S. of spreading disinformation.
