Law enforcement agencies of several European countries, together with the FBI and Europol, seized the infrastructure of the ChipMixer cryptomixer and seized €44 million worth of bitcoins, the EU Police Service reported. The authorities of Germany and the United States, with the support of the intelligence services of Belgium, Poland and Switzerland, turned off the infrastructure of the platform.
During the operation, 4 servers, 7 TB of data and 1.9 thousand bitcoins (€44.2 million) were confiscated. The ChipMixer website is also no longer active.
Established in mid-2017, the ChipMixer service, according to Europol, has been involved in money laundering and allowed users to hide traces of crimes related to drug or weapons trafficking, ransomware attacks and fraud. It is believed that a total of 152,000 BTC (about €2.73 billion) was laundered through the platform.
A cryptocurrency mixer (tumbler) is a service that mixes different streams of a potentially identifiable cryptocurrency. This increases the anonymity of transactions, as it makes it difficult to track the cryptocurrency.
In August 2022, the Tornado Cash cryptocurrency platform was sanctioned by the US Department of the Treasury. The work of Tornado Cash was blocked due to the fact that it was used in the laundering of billions of dollars, as well as to circumvent sanctions against the DPRK.
