Polish authorities arrested four members of an organized cybercrime group involved in SIM swap attacks targeting cryptocurrency exchanges. The group allegedly gained unauthorized access to telecommunications infrastructure and employee email accounts using social engineering and specialized software. This access enabled them to hijack victims' phone numbers, intercept communications, and drain accounts on cryptocurrency platforms, resulting in millions of dollars in theft. The stolen funds were laundered through a complex financial network involving multiple bank accounts and digital wallets. The suspects face serious charges, including organized crime and money laundering, with potential penalties of up to 25 years in prison. The investigation is ongoing, with international cooperation from the FBI and HSI.
