According to Poland's Central Bureau for Combating Cybercrime (CBZC), Polish authorities arrested four members of an organized criminal group accused of carrying out SIM swap attacks on cryptocurrency exchanges, stealing digital assets, and laundering the proceeds. The operation was supported by U.S. FBI and Homeland Security Investigations agents.
The suspects used specialized software and social engineering techniques to breach IT infrastructure of entities cooperating with telecommunications operators, then conducted SIM swap attacks to hijack phone numbers and gain control of cryptocurrency exchange accounts. The group allegedly laundered the stolen funds through personal bank accounts in Poland and abroad, international payment platforms, and digital wallets, with the total value of laundered funds estimated to exceed tens of millions of Polish zlotys. All four suspects face charges including participation in an organized criminal group, theft by hacking, and money laundering, carrying penalties of up to 25 years in prison.
