In a significant crackdown on cryptocurrency laundering, Europol, in collaboration with Swiss and German law enforcement, has successfully dismantled the notorious ‘Cryptomixer’ service. This illegal operation, known for obfuscating the origins of criminal funds, was targeted during a meticulously coordinated action week spanning from November 24 to 28, 2025, in Zurich, Switzerland. The operation led to the seizure of three servers, the cryptomixer.io domain, and over 12 terabytes of data. Authorities also confiscated more than EUR 25 million in Bitcoin, striking a major blow to the cybercriminal community. The service, which has been operational since 2016, had processed over EUR 1.3 billion in Bitcoin, serving as a preferred platform for money launderers involved in various illegal activities including drug and weapons trafficking, ransomware attacks, and payment card fraud. Cryptomixer offered its users the ability to mix their cryptocurrency transactions with others, making it extremely difficult to trace individual transactions on the blockchain. This capability made it a popular choice among criminals looking to launder their illicit proceeds and eventually convert them into fiat currency. The operation’s success was underpinned by the strategic exchange of information within the Joint Cybercrime Action Taskforce (J-CAT) hosted at Europol’s headquarters in The Hague. This recent takedown is a continuation of Europol’s intensified efforts to combat cyber-enabled financial crimes, following the March 2023 shutdown of ‘Chipmixer,’ another large mixing service. The collaborative efforts of Europol, Eurojust, and the European Multidisciplinary Platform Against Criminal Threats (EMPACT) have been crucial in these operations, showcasing the power of international law enforcement cooperation in tackling complex cybercrime and cryptocurrency laundering networks.
