A substantial breach of U.S. telecom networks, particularly affecting T-Mobile, has been attributed to Chinese hackers in a significant cyber-espionage operation. The FBI and CISA have confirmed that numerous U.S. telecommunications providers were infiltrated, leading to the compromise of sensitive data, including communications of government officials. Reports indicate that the attackers targeted commercial telecommunications infrastructure for surveillance purposes, with findings revealing a broad and significant spying effort. The U.S. government officials are now facing heightened risks as investigations into this vast Chinese cyber-espionage campaign continue.
