After months of hunting for intruders, T-Mobile's security chief Jeff Simon and colleagues traveled to a Bellevue, Washington data center and physically cut the network cable connecting a compromised system to the outside world. The Salt Typhoon campaign compromised hundreds of companies including AT&T, Verizon, Viasat, Charter, and Windstream, seeking phone records and data on senior government officials, but T-Mobile avoided a large-scale breach by catching the activity early. ## Full article daily.dev links to this article rather than hosting it.

T-Mobile's cybersecurity chief Jeff Simon and three colleagues drove to a data center in Bellevue, Washington, located the compromised system, and physically cut the cable connecting it to the outside world using scissors. This came after months of hunting for suspected intruders, once unusual traffic was traced to a router belonging to another unnamed telecom company. The quick physical response helped T-Mobile avoid the large-scale breach that hit other carriers. _Security teams tracking nation-state telecom breaches like Salt Typhoon can follow incident response details on daily.dev._ ### Which companies were affected by the Salt Typhoon Chinese hacking campaign?
