Law enforcement agencies across Europe have taken down Cryptomixer, a cryptocurrency mixing service that helped launder $1.5 billion in Bitcoin over nearly a decade. The service allowed users to obscure their cryptocurrency transactions by pooling funds with other users before returning untraceable coins.
Operation Olympia, led by German and Swiss authorities with Europol support, targeted the platform frequently used by criminals to launder proceeds from ransomware attacks, credit card fraud, and drug trafficking. Investigators seized three servers in Switzerland, the platform's web domain, 12 terabytes of data, and $29 million worth of Bitcoin. No arrests have been announced yet.
