European Police Dismantle Crypto Mixing Site Involved in Laundering €1.3 Billion
In a major blow to global cybercrime, European law enforcement agencies have dismantled Cryptomixer, a prominent cryptocurrency mixing service accused of laundering more than €1.3 billion ($1.51 billion) in illicit funds since its inception in 2016. The operation, carried out between November 24 and 28, 2025, targeted the infrastructure behind the platform, marking one of the largest seizures of its kind in recent years.
Cryptomixer was widely used by ransomware gangs, dark web market operators, and other criminal networks to obscure the origins of stolen cryptocurrency. By pooling deposits from multiple users and redistributing them at random intervals, the service made it extremely difficult for authorities to trace the flow of funds on the blockchain. This process, known as “mixing” or “tumbling,” is a favored technique for criminals seeking to cash out illicit proceeds through cryptocurrency exchanges.
The takedown, dubbed Operation Olympia, was led by police forces in Switzerland and Germany, with critical support from Europol and Eurojust. Authorities seized three servers located in Switzerland, the cryptomixer.io domain, and more than 12 terabytes of operational data. In addition, they confiscated over €25 million ($29 million) in Bitcoin believed to be proceeds of crime.
“Deposited funds from various users were pooled for a long and randomized period before being redistributed to destination addresses, again at random times,” Europol explained in a statement. “As many digital currencies provide a public ledger of all transactions, mixing services make it difficult to trace specific coins, thus concealing the origin of cryptocurrency.”
Cryptomixer was accessible both on the clear web and the dark web, making it a go-to platform for a wide range of illegal activities, including ransomware attacks, payment card fraud, and the trafficking of drugs and weapons. The service was particularly popular among high-profile cybercriminal groups, including the North Korean-linked Lazarus Group, which has used similar platforms to launder funds stolen in major hacks.
The operation was part of a broader international effort to disrupt the infrastructure that enables cybercriminals to launder money and evade detection. Europol’s Joint Cybercrime Action Taskforce (J-CAT) played a key role in coordinating intelligence sharing and forensic analysis among participating agencies. This marks the latest in a series of high-profile mixer takedowns, following the 2023 dismantling of ChipMixer, which was then considered the largest crypto-mixing service on the dark web.
Following the raid, the Cryptomixer website now displays a seizure notice warning that anyone using or operating cybercriminal services is subject to investigation and prosecution. Authorities say the data seized could provide valuable leads in ongoing investigations and help identify individuals behind other illicit activities.
The crackdown underscores the growing focus of law enforcement on tracing and disrupting cryptocurrency flows linked to crime. As digital currencies become more mainstream, authorities are stepping up efforts to close loopholes exploited by criminals, targeting not just the perpetrators but also the platforms that facilitate their operations.
With the seizure of Cryptomixer, European police have dealt a significant setback to the cybercriminal ecosystem, sending a clear message that mixing services used for money laundering will not go unchecked.
