Chinese Cyberattack Hits More US Telecom Companies

U.S. Telecommunications Companies Compromised by Chinese Cyber Threat Group Salt Typhoon

In a significant escalation of cyber threats, U.S. telecommunications companies, including Windstream, Consolidated Communications, and Charter Communications, have reportedly fallen victim to the Chinese state-backed hacker group known as Salt Typhoon. This alarming development, first reported by the Wall Street Journal, adds to a growing list of nine telecom firms targeted across the nation, including major players like AT&T, T-Mobile, and Verizon.

The Salt Typhoon cyberespionage operation has raised serious concerns about the security of critical infrastructure in the United States. Notably, the attacks have exploited vulnerabilities in Fortinet network devices and large Cisco routers, as detailed by the Wall Street Journal. National Security Advisor Jake Sullivan briefed U.S. tech and telecommunications executives in late 2023 on these threats, highlighting the capability of Chinese threat actors to execute destructive cyberattacks aimed at the country’s power grids, ports, and other essential services.
