European Agencies Shut Down Cryptomixer Laundering 1.5B Euros

European law enforcement agencies have shut down Cryptomixer, a cryptocurrency mixing service accused of laundering more than 1.5 billion euros worth of Bitcoin for cybercriminals, Europol announced on Monday. The operation, conducted from November 24 to 28 in Zurich, Switzerland, involved coordinated efforts by Swiss and German authorities and resulted in the seizure of three servers, the cryptomixer.io domain, over 12 terabytes of data, and approximately 28 million euros in Bitcoin.

The takedown, known as Operation Olympia, was supervised by Europol and supported by Eurojust, the European Union's judicial cooperation agency. Investigators from Germany's Federal Criminal Police Office, the Frankfurt Cyber Crime Centre, and Swiss entities including the Zurich City Police, Zurich Cantonal Police, and the Zurich Public Prosecutor participated. Europol's Joint Cybercrime Action Taskforce facilitated intelligence sharing, forensic analysis, and on-site expertise during the seizures. The service's websites, accessible via both the clear web and the dark web through the Tor browser, now display a seizure notice warning users and operators of potential investigation and prosecution.
