The U.S. Department of Justice (“DOJ”) announced on March 15, 2023 that in a coordinated effort between U.S. Federal Bureau of Investigations, Europol, and German police, the darknet cryptocurrency mixing service ChipMixer has been shut down. The operation involved the U.S. government’s court-authorized seizure of two domains that directed users to the ChipMixer service and one Github account. In addition, German authorities seized $46 million in cryptocurrency, as well as ChipMixer’s back-end servers used to run the site.
Further, the U.S. Attorney’s Office for the Eastern District of Pennsylvania filed a criminal complaint against ChipMixer’s suspected founder, Vietnamese national, Minh Quoc Nguyen (“Nguyen”), alleging that Nguyen openly flouted financial regulations and instructed users how to use ChipMixer to evade reporting requirements while obscuring his true name under a series of stolen and fictitious identities. The complaint also alleges that ChipMixer, described as a popular platform for laundering illicit funds gained from unlawful activities like drug trafficking, ransomware attacks (according to Europol, ransomware actors Zeppelin, SunCrypt, Mamba, Dharma, Lockbit have used ChipMixer), and payment card fraud, was used to launder more than $3 billion in cryptocurrency since 2017. Nguyen has been charged with money laundering, operating an unlicensed money transmitting business, and identity theft in connection with the operation of ChipMixer.
