A cyberattack linked to the Chinese government has infiltrated the networks of several major U.S. broadband providers, including Verizon Communications, AT&T Inc., and Lumen Technologies. The breach exploited vulnerabilities in lawful access systems used for court-authorized wiretapping requests, potentially granting attackers access to sensitive information and raising significant national security concerns. The hacking campaign, referred to as "Salt Typhoon," highlights how such systems can become major sources of personal and national insecurity by exposing weaknesses in the telecommunications infrastructure.
