    Germany’s federal investigative police worked together with Frankfurt prosecutors and officials in Zurich to disable the service last week, per Reuters. Investigators believe the platform, which launched in 2016, generated billions of euros in revenue, largely from activities tied to online crime.

    Cryptocurrency mixers function by splitting and reshuffling digital funds to hide the source of the money, making it difficult for authorities to trace transfers. In this case, the crackdown was led by Zurich law enforcement, who seized servers located in Switzerland and took control of the Cryptomixer.io web domain. Governments also confiscated valuable assets, including more than 12 terabytes of data and bitcoin holdings worth over 25 million euros.

    Officials say the operation involved Europol as well as agencies from the European Union and the United States. According to Reuters, Europol has identified the platform as a tool suspected of supporting a range of cybercrimes, from ransomware to money laundering. Investigators expect that the evidence gathered will aid in future criminal probes.

    “The findings will also contribute to the investigation of further cybercrimes,” the German Federal Criminal Police Office stated.

    Europol noted in its own statement that the service was accessible not only on the open internet but also via the dark web, a common refuge for criminal marketplaces.
