Europol and Eurojust take down “Cryptomixer” used to launder money

Europol, Eurojust, and law enforcement authorities from Germany and Switzerland have taken down a cryptocurrency mixing service that was most likely used by criminals to launder their illicitly gained revenues.

During the operation, which was from November 24th to 28th, 2025, three servers, which were located in Zurich, Switzerland, were seized, along with the cryptomixer.io domain.

In addition, over 12 terabytes of data and more than €25 million worth of Bitcoin were confiscated.

Users who try to visit the website will see a so-called splash page, stating that the domain has been seized by local authorities.

A crypto mixing service, or ‘cryptomixer,’ is often used by cybercriminals to launder cryptocurrency by pooling users’ deposited funds for a prolonged, randomized period of time and then redistributing them to various destination addresses.

Its software blocks the traceability of cryptocurrency on the blockchain, making it the perfect tool for criminals to hide their illegally gained money.

“Mixing services such as Cryptomixer offer their clients anonymity and are often used before criminals redirect their laundered assets to cryptocurrency exchanges. This allows ‘cleaned’ cryptocurrency to be exchanged for other cryptocurrencies or for FIAT currency through cash machines or bank accounts,” Europol says in a statement.

Since 2016, when the ‘Cryptomixer’ made its first appearance, over €1.3 billion had been laundered through the service.

Europol and Eurojust provided technical support, forensic assistance, and legal advice to the law enforcement agencies that participated.

Throughout the operation, Europol facilitated the exchange of information, coordinated the involved partners, and hosted operational meetings. A joint investigation team was set up at Eurojust to allow real-time exchange of information and evidence.

Back in March 2023, Europol was involved in taking down ‘Chipmixer,’ which was considered the largest mixing service at the time. According to investigators, the crypto mixing service may have facilitated the laundering of 152,000 Bitcoins, or approximately €2.73 billion.

Law enforcement authorities from Belgium, Germany, Poland, Switzerland, and the United States were involved in taking ‘Chipmixer’ offline.
