The US may have uncovered the nation's largest "SIM swap" scheme yet, charging a Chicago man and co-conspirators with allegedly stealing $400 million in cryptocurrency by targeting over 50 victims in more than a dozen states, including one company.

A recent indictment alleged that Robert Powell—using online monikers "R," "R$," and "ElSwapo1"—was the "head of a SIM swapping group" called the “Powell SIM Swapping Crew.” He allegedly conspired with Indiana man Carter Rohn (aka "Carti" and "Punslayer") and Colorado woman Emily Hernandez (allegedly aka "Em") to gain access to victims' devices and "carry out fraudulent SIM swap attacks" between March 2021 and April 2023.

SIM-swap attacks occur when someone fraudulently induces a wireless carrier to "reassign a cell phone number from the legitimate subscriber or user’s SIM card to a SIM card controlled by a criminal actor," the indictment said. Once the swap occurs, the bad actor can defeat multi-factor authentication protections and access online accounts to steal data or money.
