“The prices advertised for a SIM-swap against T-Mobile customers in the latter half of 2022 ranged between USD $1,000 and $1,500, while SIM-swaps offered against AT&T and Verizon customers often cost well more than twice that amount.”
Three groups posted “Tmo up!” on 104 separate days in the last seven and a half months of 2022. Each time they had phished an employee into T-Mobile’s internal tools. T-Mobile made nearly $80 billion last year and still hasn’t handed its 71,000 staff hardware security keys, the one fix that provably stops this. The criminals priced its security at half of AT&T’s.
