SIM swap is an old-school but deadly trick; phone numbers have become the biggest single point of failure, and 2FA also needs to be upgraded to hardware keys.

According to Bitdefender, Poland's Central Cybercrime Bureau (CBZC) arrested four suspects involved in SIM swap crypto theft and money laundering. Police said the group hijacked victims' phone numbers to intercept text messages and emails, thereby breaking into online accounts including crypto exchange accounts and stealing digital assets. The funds were transferred through bank accounts in Poland and abroad, international payment platforms, and multi-currency digital wallets, involving millions of dollars in money laundering. The operation was assisted by the U.S. Federal Bureau of Investigation (FBI) and the U.S. Homeland Security Investigations (HSI). The four suspects have been temporarily detained, and the charges are still pending judicial proceedings.
