The U.S. Treasury has lifted sanctions on Tornado Cash, a crypto mixer previously linked to North Korean money laundering of $7 billion. This decision follows a legal battle and allows U.S. entities to engage with Tornado Cash, which blends crypto to obscure its origins. Despite the delisting, the Treasury expressed continued concern over North Korean cyber threats. In 2022, the entity was accused of facilitating hacks to fund the country's nuclear program. Founders of Tornado Cash faced criminal charges in 2023 for money laundering and sanctions violations.
