The United States Federal Bureau of Investigation (FBI) and Ukrainian law enforcement have seized the domains of nine digital currency exchanges allegedly aiding cybercriminals in money laundering activities.

The FBI claimed the exchanges provided entirely anonymous digital currency exchange services to their users, with “lax” anti-money laundering measures and minimal KYC information.

These unlicensed exchanges are seen as “important hubs in the cybercrime ecosystem,” and many were advertised on online forums dedicated to discussing criminal activity.

The FBI has been involved in various cryptocurrency-related issues recently, including conducting searches and seizures of suspected criminals’ assets. The latest seizure shows the government’s continued efforts to crack down on illegal activities in the crypto industry.
