Overview

• T-Mobile detected and blocked recent attempts by hackers to infiltrate its systems, preventing access to sensitive customer data and disruption of services.
• The attack originated from a compromised wireline provider's network, which T-Mobile quickly disconnected to mitigate further risk.
• The hacking attempts share similarities with 'Salt Typhoon,' a Chinese-linked cyberespionage group, though T-Mobile has not confirmed the attackers' identity.
• Salt Typhoon has been linked to breaches of other U.S. telecom providers, including AT&T and Verizon, targeting sensitive communications and government data.
• T-Mobile has shared its findings with U.S. authorities and emphasized its strengthened cybersecurity measures following past breaches.
