Recent reports reveal that Chinese hackers have compromised a broader range of US telecommunications companies than previously known. In addition to earlier breaches involving AT&T and Verizon, the cyberattacks have now been found to affect Charter Communications, Consolidated Communications, Windstream, Lumen Technologies, and T-Mobile. The hacking group, identified as Salt Typhoon and linked to Chinese intelligence, exploited vulnerabilities in network devices from security vendors such as Fortinet and Cisco Systems.

The Wall Street Journal reports that US National Security Adviser Jake Sullivan informed telecommunications and technology executives in a confidential meeting in late 2023 that these hackers had developed the capability to disrupt critical US infrastructure, including ports and power grids. While companies like AT&T and Verizon have stated that their networks are now secure and that they are collaborating with law enforcement, concerns persist about the extent and impact of these breaches.

China has denied involvement in these cyber activities, accusing the United States of disseminating disinformation. Nonetheless, the revelations have intensified discussions about national security and the resilience of US critical infrastructure against sophisticated cyber threats. The situation underscores the ongoing challenges in safeguarding sensitive communications and infrastructure from state-sponsored cyber espionage.
