Authorities across Europe have shut down a crypto-mixing service “Cryptomixer,”
allegedly used by cybercriminals to launder Bitcoin. They
seized millions in crypto, critical servers, and terabytes of data.
Law enforcement
agencies from Switzerland and Germany, coordinated by Europol, targeted
Cryptomixer between November 24 and 28, 2025. It is alleged to have laundered over €1.3
billion ($1.51 billion) in Bitcoin since 2016.
According to Europol, authorities confiscated three
servers, the platform’s domain, more than €25 million ($29 million) in BTC, and
over 12 terabytes of operational data.

Europol Leads Cross-Border Raid
Europol’s cybercrime experts coordinated the
operation, provided forensic support, and facilitated real-time information
exchange among participating agencies. Following the takedown, a seizure banner
was placed on the Cryptomixer website.
Cryptomixer was reportedly a hybrid mixing service
accessible via both the clear web and the dark web. It allowed users to deposit
Bitcoin, which was then pooled, randomized, and redistributed to destination
addresses over extended periods.
The service was widely used by ransomware groups, dark
web marketplaces, and other criminal networks to obscure the origin of illicit
funds, including proceeds from drug trafficking, weapons sales, ransomware
attacks, and payment-card fraud.
The raid involved Germany’s Federal Criminal Police
Office and the Prosecutor General’s Cyber Crime Centre, as well as Zurich City
Police, Zurich Cantonal Police, and the Public Prosecutor’s Office in
Switzerland. Eurojust provided legal coordination and operational support.
Coordination Across Borders
Europol facilitated the exchange of intelligence
through its Joint Cybercrime Action Taskforce (J-CAT), helping member states
share expertise and conduct a coordinated takedown.
The Cryptomixer shutdown follows Europol’s 2023
dismantling of ChipMixer, which was then the largest crypto-mixing service. Authorities
continue to prioritize tracing illicit cryptocurrency flows and targeting
platforms that facilitate money laundering.
In a similar crackdown, a Europe-wide enforcement effort recently traced more than €47 million in cryptocurrency moving through accounts linked to illegal streaming and digital piracy networks. Authorities said the findings mark one of the largest financial-tracking exercises ever conducted against online intellectual property crime.
Around the same time, another large-scale operation took down more than 1,400 fraudulent online trading platforms targeting retail investors. According to Reuters, German investigators, together with BaFin,
Europol and Bulgarian authorities, traced networks of fake brokers that
persuaded users to invest significant amounts with promises of high returns.
