Four Arrested in Poland Over Crypto SIM-Swap Attacks, ZachXBT Links Merry to Case

Polish authorities have arrested four people connected to a crypto SIM-swapping and money laundering operation. The suspects allegedly breached telecom infrastructure and hijacked email accounts to take over cryptocurrency exchange accounts.

Blockchain investigator ZachXBT identified one of the detained individuals as Wojtek Kulisz, a threat actor known as Merry, based on images from the police raid shared by authorities.

The group reportedly treated cybercrime as a regular income source, using multiple bank accounts across different countries and digital wallets to move stolen funds. The total value is estimated at tens of millions of Polish zloty.

The arrests were carried out by the Polish Cybercrime Bureau with assistance from the FBI and Homeland Security Investigations. The suspects face up to 25 years in prison for hacking, money laundering, and participation in an organized criminal group.
