In May 2022, OFAC sanctioned a mixer for the first time ever when it designated Blender.io for its role in laundering cryptocurrency stolen by North Korean hacking syndicate Lazarus Group. The sanctioning of prominent mixers may have contributed to two trends we observed in 2022: The total amount of cryptocurrency sent to mixers fell significantly, and the funds that did travel to mixers were more likely to come from illicit sources. The result is that each user’s cryptocurrency can now only be traced back to the mixer, rather than to its original source, unless special blockchain analysis techniques are employed. The graph shows that most cryptocurrency money laundering is facilitated by a very small group of people.
