Europol and German–Swiss authorities shut down the ‘Cryptomixer’ laundering service in a coordinated November raid, seizing €25 million in crypto tied to cybercrime.

Europol, together with law enforcement in Germany and Switzerland, has dismantled the crypto-mixing service Cryptomixer (cryptomixer.io) in a coordinated enforcement action that took place between 24 and 28 November 2025 in Zurich. Authorities seized three servers in Switzerland, took control of the service’s domain, obtained more than 12 terabytes of data, and confiscated over €25 million (around $27–29 million) in Bitcoin allegedly linked to cybercrime. A seizure banner was placed on the Cryptomixer website after law enforcement took over the infrastructure. According to Europol and supporting reports, Cryptomixer has operated since 2016 as a hybrid mixing service accessible on both the clear web and dark web, allegedly processing over €1.3 billion (roughly $1.4–1.5 billion) in Bitcoin during that period. The platform pooled users’ deposits and returned mixed coins to new addresses, obscuring transaction trails on the blockchain and making it harder to link funds to their criminal origin. Investigators say the mixer became a preferred laundering hub for various cybercriminal groups, including actors involved in ransomware attacks, dark‑web markets, drug and weapons trafficking, payment card fraud, and other illicit activities. This takedown is part of a broader pattern of international operations targeting crypto-mixing infrastructure viewed by regulators and law enforcement as critical to the laundering of digital-asset proceeds from cybercrime. By seizing Cryptomixer’s servers, domain, data trove, and associated funds, authorities gained both an intelligence source on past transactions and a high‑visibility enforcement precedent signalling increased capacity to disrupt services that advertise strong on‑chain anonymity but are allegedly used primarily to launder illicit proceeds. The operation, coordinated under the code name sometimes reported as “Operation Olympia,” reflects growing collaboration between EU agencies such as Europol and Eurojust and national authorities in complex cross‑border crypto investigations.
