Europol Cracks $1.4B Cryptomixer, Seizes $27M and 12TB of Data

December 2, 2025

Europol, the EU’s law enforcement agency that helps fight serious cross-border crime, has joined German and Swiss authorities to shut down one of Europe’s largest crypto-mixing operations, seizing €25 million ($27 million) in Bitcoin and over 12 terabytes of user data.

Key Points

  • Europol, along with German and Swiss authorities, shut down Cryptomixer, one of Europe’s largest crypto-mixing services, seizing €25 million in Bitcoin and 12 terabytes of user data.
  • Cryptomixer reportedly facilitated cybercrime and money laundering by anonymizing transactions for ransomware groups, illegal marketplaces, and other criminal networks.
  • Since its launch in 2016, the platform is believed to have processed over €1.3 billion in Bitcoin, highlighting the scale of illicit activity it enabled.

According to an official Europol press release, authorities from Europol, Germany, and Switzerland carried out an operation in Zurich targeting Cryptomixer, a crypto-mixing service suspected of enabling cybercrime and money laundering.

The operation led to the seizure of three servers in Switzerland, the takedown of the cryptomixer.io domain, and the confiscation of more than 12 terabytes of data and over EUR 25 million in Bitcoin. Following the shutdown, authorities replaced the site with an official seizure notice.

The service functioned by pooling user deposits for extended, randomized periods before dispersing the funds to destination addresses at unpredictable intervals. Since launching in 2016, the platform is believed to have processed more than EUR 1.3 billion in Bitcoin.

Cryptomixer operated as a hybrid crypto-mixing platform available on both the open web and the dark web, giving users a tool to obscure the origin of digital funds. Authorities say the service became a preferred laundering channel for ransomware operators, illegal online marketplaces, and other criminal networks because its software disrupted blockchain traceability.

By anonymizing transactions before they were moved to cryptocurrency exchanges, the platform enabled users to convert “cleaned” assets into other digital currencies or even traditional fiat money through cash-out services, ATMs, or bank accounts. Its role in masking proceeds linked to drug trafficking, weapons trafficking, ransomware schemes, and payment card fraud made it a central infrastructure for online criminal finance.

The takedown of Cryptomixer marks another step in Europe’s broader effort to limit illicit financial activity within the digital asset sector. Investigators are increasingly focused on services that exploit privacy tools to mask unlawful transactions, reflecting a shift toward more proactive enforcement in the crypto ecosystem.

While privacy-enhancing technologies remain widely used for legitimate purposes, authorities say operations like this emphasize how easily they can be repurposed by criminal groups.
