T-Mobile US takes a victory lap after stopping cyberattacks: 'Other providers may be seeing different outcomes'

Suspected China-linked APT "Salt Typhoon" has compromised a US wireline provider and attempted to breach T-Mobile US systems; other major U.S. carriers have reportedly been targeted as part of an extensive espionage campaign that involved access to systems used for communications wiretapping and the theft of call records and intercepted communications. T-Mobile severed connections to the compromised provider and reports no sensitive customer data was taken from its network, though the wider campaign poses significant national-security and privacy risks.
