Hackers linked to the Chinese government breached US telecom networks
Hackers linked to the Chinese government have compromised US telecom companies' law enforcement wiretap networks mandated under a 30-year-old federal surveillance law called Communications Assistance for Law Enforcement Act (CALEA). The group, known as Salt Typhoon, had access to systems at Verizon Communications, AT&T, and Lumen Technologies. Security analysts are still assessing the extent of data stolen during the breach, which is said to be significant. China has denied its involvement in the cyberattacks.
