An international law enforcement operation coordinated by Europol has resulted in the arrest of 354 suspected dark web vendors and buyers across 14 countries. Authorities seized more than five tonnes of illegal drugs and criminal assets exceeding €210 million during a major crackdown on online criminal networks involved in drug trafficking, cybercrime and firearms offences.
The operation, named TorNado, was conducted between May 2025 and October 2026. Investigators carried out hundreds of searches and identified individuals suspected of using hidden online marketplaces to facilitate illegal transactions across international borders.
How Did Police Identify Dark Web Criminals?
Operation TorNado targeted individuals operating through several major dark web marketplaces, including Archetyp, Bohemia, Nemesis, Kingdom and Tor2Door. Investigators examined activity linked to these platforms following their disruption, focusing on identifying vendors, customers and individuals supporting criminal transactions.
The investigation also extended to independent online shops, dark web forums and encrypted messaging services allegedly used to conduct illegal business. National authorities conducted separate investigations while coordinating intelligence and forensic findings with Europol to identify suspects operating across different jurisdictions.

The United States recorded the highest number of arrests, with 132 suspects detained. The United Kingdom followed with 59 arrests, Hungary reported 45, Germany recorded 41 and France arrested 23 individuals. Other arrests were made in New Zealand, the Netherlands, Slovenia, Austria, Ireland, Czechia, Australia and Finland.
The operation demonstrated how information recovered from disrupted marketplaces could help investigators trace criminal activity beyond the original websites.
What Did Authorities Seize During the Operation?
Law enforcement agencies recovered substantial quantities of illegal drugs, firearms, cash and cryptocurrencies during the coordinated action.
In European countries, authorities seized approximately 950 kilograms of illicit drugs. The largest reported recoveries included 150 kilograms of amphetamines in Germany, 150 kilograms of ketamine in the United Kingdom, 40 kilograms of MDMA in the Netherlands and 50 kilograms of cannabis in France.
Other seizures included cocaine, prescription tablets, psilocybin mushrooms and vaping products containing THC. European investigators also confiscated 57 firearms and ammunition, along with more than €60 million in cash and cryptocurrencies.
In the United States, authorities seized more than 4.8 tonnes of illegal drugs, 152 firearms and criminal assets exceeding €150 million. The combined recoveries demonstrate the extensive financial and logistical networks supporting illegal trade through dark web platforms.
Why Are Dark Web Criminal Networks Difficult to Eliminate?
Investigators found that dark web criminal networks continue to adapt even after major marketplaces are shut down. Criminal operators increasingly move between smaller platforms, encrypted communication channels and specialised marketplaces to continue their activities.
Europol identified growing fragmentation within the underground economy, with different platforms concentrating on particular criminal services. The increasing overlap between dark web marketplaces and encrypted messaging applications has also complicated efforts to track illegal transactions.
During Operation TorNado, Europol supported national police agencies through intelligence sharing, forensic examinations and blockchain analysis. These methods helped investigators examine suspicious transactions, identify possible connections between suspects and coordinate investigations across borders.
The operation highlights the importance of sustained international cooperation in tackling cyber-enabled organised crime. Authorities continue to face challenges as criminal networks rapidly replace disrupted marketplaces and develop alternative channels for illegal transactions.
