What happened
A US Attorney's Office charged a former mobile phone company employee with accepting bribes to perform unauthorized SIM swaps on customer accounts. Between October 20 and November 9, 2018, a co-conspirator sent him customer phone numbers, four-digit PINs and destination SIM numbers, and he executed the swaps from inside the carrier's systems. At least 19 customers were targeted in the wider conspiracy, including a New Orleans physician.
How the deception worked
The deceived party here was the carrier itself, not a customer. Rather than talk a retail rep into a fraudulent swap, the conspiracy simply put one on payroll. A co-conspirator messaged Defiore a target's phone number, account PIN and the SIM identifier to swap the line to; Defiore, who worked at the carrier from August 2017 to November 2018, used his legitimate employee access to execute the change and was paid roughly $500 per day. Because the change was made by an authorized account with a valid business reason on its face, none of the carrier's customer-facing verification controls applied. The hijacked numbers then received the victims' SMS authentication codes.

The control that would have caught it· our reading, not a claim from the sources
SIM-change transactions need behavioral monitoring on the employee side, including per-rep swap-rate baselining and out-of-band customer confirmation, since insider abuse looks identical to authorized work in the logs.
