On March 15, U.S. law enforcement, along with German criminal authorities, disabled a darknet cryptocurrency “mixing” service used to allegedly launder more than $3 billion in cryptocurrency underlying ransomware, darknet market activities, fraud, cryptocurrency heists, hacking schemes, and other activities. According to the DOJ’s announcement, law enforcement agencies seized two domains and back-end servers, as well as more than $46 million in cryptocurrency. The DOJ claimed the mixing service allowed criminals to obfuscate the source of stolen cryptocurrency by commingling users’ cryptocurrency in a way that made it difficult to trace the transactions. In conjunction with the action taken against the mixing service, a Vietnamese national responsible for creating and operating the online infrastructure was charged with money laundering, operating an unlicensed money transmitting business, and identity theft connected to the mixing service. Separate actions have also been taken by German law enforcement authorities, the DOJ said. “Criminals have long sought to launder the proceeds of their illegal activity through various means,” Special Agent in Charge Jacqueline Maguire of the FBI Philadelphia Field Office said in the announcement. “Technology has changed the game, though[.] In response, the FBI continues to evolve in the ways we ‘follow the money’ of illegal enterprise, employing all the tools and techniques at our disposal and drawing on our strong partnerships at home and around the globe.”
