Europol busted Cryptomixer – a platform that had been laundering digital assets for cybercriminals for 9 years. The action was a coordinated action of European law enforcement agencies. Scale? Over EUR 1.3 billion in Bitcoin. Importantly, the hybrid mixing service worked on both the clearnet and the dark web.
Cryptomixet – three servers, 12 TB of data and EUR 25 million in BTC
The operation was successful: three servers in Switzerland were secured, the cryptomixer.io domain was taken over and over 12 terabytes of data were confiscated. Importantly, over EUR 25 million in Bitcoin ended up in the hands of law enforcement authorities. After taking control of the website, the officers placed a banner on the website informing about the closure of the platform. Something like a trophy and at the same time a warning sign for other cybercriminals – we got them, we’ll get you too.
A paradise for cybercriminals since 2016
Cryptomixer was not an amateur operation. Since its establishment in 2016, the service has handled transactions with a total value exceeding EUR 1.3 billion in BTC. The platform specialized in obfuscating the origins of funds for ransomware groups, underground economy forums and dark web marketplaces.

A bridge between the dark web and the legal market
Hashing services are a key element in the crypto laundering chain. Criminals used Cryptomixer before redirecting funds to cryptocurrency exchanges, where they exchanged the “cleaned” assets for other cryptocurrencies or fiat – through ATMs or traditional bank accounts.
Polish perspective
Although there is no official information about the participation of Polish services in the attack on Cryptomixer, the ChipMixer campaign from 2023 shows that Polish specialists are increasingly actively participating in international actions against cryptocurrency crime. In an era when cybercrime knows no boundaries, such cooperation becomes a necessity and Polish officers show that they are in this league. This is good news for the domestic digital asset market, which needs both innovation and order. Especially in the light of the still unresolved cryptocurrency act.
