OFAC sanctioned Tornado Cash for providing mixing services used to launder more than $7 billion in virtual currency, including proceeds from major cyber-enabled thefts. Treasury stated that Tornado Cash was used to launder over $455 million stolen by Lazarus Group, a DPRK state-sponsored hacking group sanctioned by the United States in 2019, describing it as the largest known virtual currency heist to date. The release also cites laundering of more than $96 million from the Harmony Bridge heist and at least $7.8 million from the Nomad heist. The action frames mixers as high-risk infrastructure for sanctions evasion and cybercrime proceeds, making the item relevant to DPRK cryptocurrency theft and laundering workflows.
