Tornado Cash was hit by U.S. sanctions in August 2022. This spurred Lazarus Group to use another mixer, Sinbad, to obfuscate their ill-gotten gains. However, Sinbad itself was seized by U.S. authorities in November, prompting Lazarus to make the shift back to Tornado Cash, Elliptic said in its blog post. One of Tornado Cash’s founders, Roman Storm, was arrested last year and is awaiting trial on money laundering charges. Another, Roman Semenov, has been charged but has yet to be arrested.
