Federal prosecutors charged two Eastern European nationals with operating AudiA6, a cryptocurrency mixing service that laundered about $389 million in bitcoin tied to darknet markets and ransomware groups.
The arrests followed a coordinated international takedown involving the U.S. Secret Service, IRS Criminal Investigation, Europol and law enforcement partners from 14 countries, the Justice Department said Thursday. Authorities seized servers and domains in the U.S., Iceland, Germany and France, froze cryptocurrency assets and replaced the AudiA6 and Dark2Web websites with seizure banners.
Ruslan Igorevich Tkachuk, 37, a Ukrainian national, and Alexander Vladimirovich Ledenev, 25, a Russian national, were arrested in Batumi, Georgia, where both resided. Each faces one count of conspiracy to launder monetary instruments and one count of sting money laundering, charges carrying a maximum of 20 years in prison. The U.S. Attorney's Office for the Eastern District of Pennsylvania said it will seek extradition.
Prosecutors allege the two men were senior members of AudiA6, which operated a cryptocurrency mixing service and managed the Dark2Web cybercrime forum where users negotiated illicit services. Since 2021, AudiA6 wallets received about 10,333 bitcoin, valued at roughly $389.7 million at the time of the transactions, with the service earning at least $10 million in commission fees by charging clients up to 5 percent per transaction.
Of those funds, approximately 393 bitcoin, worth about $19.2 million, were traced directly to known darknet markets, ransomware groups and other criminal sources, with additional funds flowing in indirectly. Despite AudiA6's promises that mixed funds would be untraceable, blockchain analysis revealed transactions could be followed through exchange records, investigators said.
The case was built partly on six undercover operations conducted between December 2022 and May 2026, in which FBI and Secret Service agents posed as criminals seeking to launder proceeds from scams and narcotics sales. In one exchange, an AudiA6 operator told an agent asking whether stolen bitcoin was acceptable: "don't care." In another, when asked whether drug sale proceeds posed too great a risk, the operator replied, "Everything like that needs to go through a mixer."
The takedown marks the latest U.S. enforcement action against crypto mixing services, which have become critical infrastructure for cybercriminals seeking to obscure the origin of illicit funds. The case is being prosecuted by Assistant U.S. Attorneys Benjamin D. Traster and Sima Kazmir in the Eastern District of Pennsylvania, where extradition proceedings in Georgia will determine how quickly the defendants face trial.
