European and American investigators have broken up one of the world’s largest online criminal trafficking operations in a series of raids in the US and Germany, authorities say.
Three German men, ages 31, 22 and 29, were arrested after the raids in three southern states on allegations they operated the so-called the “Wall Street Market” darknet platform, which hosted about 5400 sellers and 1.15 million customer accounts, Frankfurt prosecutor Georg Ungefuk told reporters in Wiesbaden.
The men, whose names weren’t released as the investigation is ongoing, face drug charges in Germany on allegations they operated the platform where cocaine, heroin and other drugs were sold, as well as forged documents and other illegal materials.
They have also been charged in the US, said Ryan White, a prosecutor with the US Attorney’s Office in Los Angeles, who travelled to Germany with FBI and DEA agents for the announcement on Friday.
“The charges filed in Germany and the United States will significantly disrupt the illegal sale of drugs on the darknet,” White told reporters.
“We believe that Wall Street Market recently became the world’s largest darknet marketplace for contraband including narcotics, hacking tools, illegal services and stolen financial data.”
Ungefuk said Wall Street Market was at least the second biggest, refusing to name others for fear of jeopardising other investigations.
In the nearly two-year operation that involved European police agency Europol and authorities in the Netherlands as well as the US and Germany, investigators pinpointed the three men as administrators of the platform on the darknet, a part of the internet often used by criminals that is hosted within an encrypted network and accessible only through anonymity-providing tools, such as the Tor browser.
Transactions were conducted using cryptocurrencies, and the suspects took a commission of between 2 per cent and 6 per cent, Ungefuk said.
The site trafficked documents such as identity papers and drivers’ licences but an estimated 60 per cent or more of the business was drug-related, he said.
Authorities swept in quickly after the platform was switched into a “maintenance mode” on April 23, and the suspects allegedly began to transfer customers’ payments to themselves in a so-called “exit scam”, Ungefuk said.
The raids culminated on Thursday with the seizure of servers while federal police confiscated 550,000 euros ($A900,000) in cash, both Bitcoin and Monero cryptocurrencies, hard drives, and other evidence in multiple raids.
In Los Angeles, two drug suppliers were arrested and authorities confiscated some $US1 million ($A1.4 million) cash, weapons and drugs in raids. White did not release their names but characterised them as “major drug traffickers” who were dealing methamphetamine and fentanyl.
Because of the clandestine nature of the operation and the difficulty of tracing cryptocurrencies, Ungefuk said it was difficult to assess the overall volume of business conducted but that “we’re talking about profits in the millions at least”.
