The US Treasury said Tuesday it has cracked down on a North Korean cryptocurrency money laundering network that laundered millions of dollars for a major player in global crypto crime in North Korea. According to a press release issued by the US Treasury's Office of Foreign Assets Control (OFAC), a United Arab Emirates-based front company called Green Alpine Trading, LLC was found to be exchanging cryptocurrencies for cash to fund North Korea. The US government's sanctions arm has blacklisted the company.
