A coordinated operation led by Europol alongside German and Swiss authorities has dismantled Cryptomixer, a long-running cryptocurrency mixing service accused of laundering over €1.3 billion ($1.5 billion) in bitcoin since its inception in 2016. The service facilitated the obfuscation of criminal proceeds by pooling user deposits for randomized durations and redistributing them through destination addresses at irregular intervals, severely impairing traceability on public blockchains.
During the action week of November 24–28, investigators seized three physical servers located in Switzerland, the official domain cryptomixer.io, and more than 25 million euros worth of bitcoin—approximately 29 million dollars at current exchange rates. Over 12 terabytes of forensic data were also confiscated, providing a trove of evidence for ongoing investigations into cybercriminal networks that relied on the platform for money-laundering purposes.
Europol characterized Cryptomixer as a “platform of choice” for various criminal activities, including ransomware groups, darknet marketplaces and organized trafficking networks, citing examples of drug and weapons trafficking proceeds laundered through the service. The agency’s press release highlighted that mixing services like Cryptomixer exploit the transparent nature of blockchain ledgers by intermingling legitimate and illicit funds, thereby concealing the origin of tainted assets.
Authorities emphasized the importance of international cooperation in tackling complex cybercrime operations that transcend national borders. The dismantling of Cryptomixer underscores the effectiveness of coordinated action combining on-site forensic support, evidence sharing and joint prosecutions. Europol’s cybercrime experts provided operational assistance throughout, facilitating real-time data exchange and strategic planning among participating agencies.
This takedown represents one of the most significant disruptions of a cryptocurrency mixer to date and serves as a warning to operators of similar services. Investigators will continue analysing the seized infrastructure and data to identify and pursue individuals responsible for operating Cryptomixer, as well as the criminal clientele that utilized the service to launder illicit proceeds. Ongoing legal proceedings are expected to focus on dismantling affiliate networks and freezing related financial assets to further weaken cyber-enabled criminal enterprises.
