T-Mobile found a Chinese hacker inside its network. So its security team drove to a data center and literally cut the cable.
- Salt Typhoon had been targeting US telecoms
- T-Mobile hunted for months
- A “powered off” router was still communicating
- The connection traced back to a disguised router in Chicago
- 4 T-Mobile employees drove to the data center
- They pulled out scissors
The attackers reached routing infrastructure at the edge of T-Mobile’s network.
They never reached the core or customer data.
Sometimes cybersecurity still comes down to: cut that the cord.
