Poland arrests four gang members involved in SIM-swapping fraud

Polish authorities arrested four members of an organized cybercrime group accused of compromising telecommunications partners and email accounts to conduct SIM-swapping attacks. The attackers hijacked phone numbers, intercepted SMS messages and email communications, and gained control of cryptocurrency exchange accounts. Investigators estimate that millions of U.S. dollars were stolen and laundered through bank accounts in multiple countries and digital wallets. The operation was conducted by Poland’s Cybercrime Bureau with support from the FBI and Homeland Security Investigations in the United States.
