Major US telecom firms confirm cyberattacks by Chinese group ‘Salt Typhoon’, sparking national security concerns

AT&T and Verizon have confirmed cyberattacks linked to a Chinese hacking group known as “Salt Typhoon,” but assured the public on Saturday that their US networks are now secure. Both companies acknowledged the breaches for the first time, stating they are cooperating with law enforcement and government agencies to address the threat. AT&T disclosed that the attackers targeted a small group of individuals tied to foreign intelligence, while Verizon emphasised that the activities have been contained following extensive remediation efforts.

The attacks, described by US officials as the most extensive telecommunications hack in the nation’s history, reportedly allowed Salt Typhoon operatives to access sensitive network systems, including the ability to geolocate individuals and record phone calls. Authorities have linked the breaches to several telecom firms, with a total of nine entities now confirmed as compromised. In response, the Cybersecurity and Infrastructure Security Agency has urged government officials to transition to encrypted communication methods.

US Senators, including Democrat Ben Ray Luján and Republican Ted Cruz, have expressed alarm over the breach’s scale, calling for stronger safeguards against future intrusions. Meanwhile, Chinese officials have denied the accusations, dismissing them as disinformation and reaffirming their opposition to cyberattacks. Despite assurances from the companies and independent cybersecurity experts, questions remain about how long it will take to fully restore public confidence in the nation’s telecommunications security.
