The U.S. Treasury Department launched an attack on the cryptocurrency mixing server Sinbad on the grounds that the service supported transactions related to a North Korean hacking group. Sinbad’s website was also blocked by the FBI, the Dutch Financial Intelligence and Investigation Office (FIOD), the Openbaar Ministryie (Dutch Prosecutor’s Office) and the Finnish National Investigation Service.
A press release from the U.S. Treasury Department describes Sinbad as “a virtual currency mixing service that serves as a primary money laundering vehicle for the OFAC-designated Lazarus Group, a state-sponsored cyber hacking group of the Democratic People’s Republic of Korea (DPRK).” (Coindesk)
