A frayed piece of yellow cable is framed and on display in T-Mobile US Inc.’s Seattle-area headquarters. A security staffer chopped it during an intense nationwide hunt through America’s phone systems for Chinese spies. “It’s a small little trophy and a remembrance,” Jeff Simon, T-Mobile’s chief information officer, said of the November night he and colleagues raced to a data center to cut the cable. In the fall of 2024, reports had recently surfaced that hackers had vacuumed up the phone data of millions of Americans – targeting the phones of Donald Trump, Kamala Harris and JD Vance – after infiltrating AT&T, Verizon and seven other US telecommunications companies. US officials accused China of backing the hackers, dubbed Salt Typhoon, in what is considered one of the most audacious cyber espionage campaigns.
