U.S. authorities have charged two alleged operators of a major cryptocurrency laundering service accused of processing hundreds of millions of dollars in digital asset transactions tied to cybercrime.
Federal prosecutors say the network, known as AudiA6, handled more than $389 million worth of cryptocurrency and received over 10,000 Bitcoin since its launch in 2021. The case marks another significant crackdown on crypto-related money laundering operations and darknet-linked financial activity.
Two Suspects Arrested in International Operation
According to the U.S. Attorney’s Office for the Eastern District of Pennsylvania, Ukrainian citizen Ruslan Igorevich Tkachuk, 37, and Russian citizen Alexander Vladimirovich Ledenev, 25, were arrested in Batumi, Georgia, on Wednesday.
The two men are currently awaiting extradition to the United States, where they face criminal charges connected to their alleged involvement in the AudiA6 cryptocurrency laundering network.
Prosecutors claim the pair acted as senior members of the operation, which allegedly helped customers conceal the origins of cryptocurrency linked to illegal activities.
Authorities further allege that Tkachuk and Ledenev managed the Dark2Web cybercrime forum, where AudiA6 advertised its laundering services to users seeking to move illicit funds through cryptocurrency networks.
Investigators Trace More Than 10,000 Bitcoin
Court documents cited by prosecutors describe how AudiA6 allegedly promoted services designed to obscure the source of traceable cryptocurrency.
According to investigators, advertisements posted on the Dark2Web forum offered users the ability to disguise cryptocurrency transactions in exchange for fees of up to 5% of the laundered amount.
Blockchain analysis conducted during the investigation reportedly found that approximately 10,333 Bitcoin had been deposited into wallets controlled by AudiA6 since 2021.
Authorities stated that around 393.39 BTC originated directly from identified illicit sources, including darknet marketplaces, ransomware groups, cybercrime services, and other criminal operations.
The remaining deposits were allegedly linked indirectly to criminal activity through transaction tracing and forensic analysis.
Global Law Enforcement Takes Down Infrastructure
The arrests were part of a large international law enforcement operation involving agencies from multiple countries.
The investigation brought together the U.S. Secret Service, IRS Criminal Investigation, Europol, and Eurojust, along with authorities from Australia, Canada, France, Georgia, Germany, Iceland, Japan, Poland, Switzerland, and the United Kingdom.
Investigators executed searches at three separate properties while targeting servers and internet domains located across the United States, Germany, Iceland, and France.
Authorities also froze cryptocurrency assets, seized electronic devices, and blocked Telegram accounts allegedly used by the network.
At the same time, law enforcement agencies replaced both the public-facing and dark web infrastructure associated with AudiA6 and Dark2Web with official seizure notices.
Charges and Ongoing Crypto Crime Crackdown
Federal prosecutors have filed one count of conspiracy to launder monetary instruments and one count of sting money laundering against both defendants.
The charges remain allegations, and both men are presumed innocent unless proven guilty in court.
The case follows a growing number of enforcement actions targeting cryptocurrency laundering operations. Earlier this year, the U.S. Department of Justice charged German citizen Owe Martin Andresen in connection with an alleged laundering scheme linked to the now-defunct Dream Market darknet marketplace.
According to prosecutors, Andresen allegedly moved funds from dormant administrator wallets before converting part of the proceeds into gold bars. Authorities claimed more than $2 million was laundered between August 2023 and April 2025, while searches uncovered roughly $1.7 million in gold bars and information tied to crypto wallets and bank accounts holding another $1.2 million in suspected proceeds.
The latest AudiA6 case highlights the increasing focus of global regulators and law enforcement agencies on dismantling cryptocurrency laundering networks and disrupting financial infrastructure used by cybercriminal organizations.
