In a shocking development, The Wall Street Journal reports that major U.S. telecommunications providers have fallen victim to a sophisticated Chinese cyber espionage campaign, potentially compromising systems used for court-authorised surveillance operations.
The breach, attributed to a Chinese state-sponsored group known as Salt Typhoon, has affected several industry giants including AT&T, Verizon, and Lumen Technologies.
Security investigators have discovered that the hackers maintained prolonged access to network infrastructure critical for processing lawful surveillance requests from U.S. authorities.
This unprecedented breach not only exposed systems used for domestic criminal and national security investigations but also gave attackers access to vast amounts of general internet traffic.
The intrusion is considered “potentially catastrophic” by security experts familiar with the matter.
The attack’s true scope remains under active investigation by both government agencies and private sector security firms, with authorities still working to determine the extent of data exposure and potential exfiltration.
