The U.S. Treasury Department has blocked a crypto mixing service from the global dollar financial system on allegations it supported transactions tied to North Korea's infamous hacking group.

Sinbad's website was also seized by the FBI, Dutch Financial Intelligence and Investigation Service (FIOD), Openbaar Ministerie (the Netherlands' public prosecutor's office) and Finnish National Bureau of Investigation.

A Treasury press release described Sinbad as "a virtual currency mixer that serves as a key money-laundering tool of the OFAC-designated Lazarus Group, a state-sponsored cyber hacking group of the Democratic People’s Republic of Korea (DPRK)."
