Federal prosecutors have brought charges against three Russian nationals for their alleged involvement in cryptocurrency mixers that have been used to launder stolen funds. Roman Vitalyevich Ostapenko, Alexander Evgenievich Oleynik, and Anton Vyachlavovich Tarasov stand accused of operating the services Blender.io and Sinbad.io. In a statement obtained by the U.S. Attorney’s Office for the Northern District of Georgia, U.S. Attorney Ryan K. Buchanan underscored the commitment to "dismantling infrastructure used by cybercriminals to steal from Americans and hide their ill-gotten gains."
Blender.io, which operated from about 2018 until it was shuttered in 2022, advertised a "No Logs Policy" and a user-friendly method of concealing the source of cryptocurrency without requiring personal details, according to the United States Attorney's Office. Following right after Blender.io, Sinbad.io launched and provided similar Bitcoin concealment services until its November 2023 takedown by authorities.
Both cryptocurrency mixing services have faced sanctions by the U.S. Department of Treasury’s Office of Foreign Assets Control (OFAC), which linked Blender.io to laundering virtual currency stolen by the Democratic People’s Republic of Korea and multiple ransomware groups. Sinbad.io was sanctioned for its utilization by a DPRK state-sponsored hacking group and other cybercriminals. Ostapenko is charged with one count of conspiracy to commit money laundering and two counts of operating an unlicensed money transmitting business, while both Oleynik and Tarasov face charges of conspiracy to launder money and operating an unlicensed money transmission business.
The indictment also brought to light the international efforts in disrupting these illegal operations, with special mention of contributions from the Netherlands’ Public Prosecution Service among others. As part of a coordinated law enforcement action, Ostapenko and Oleynik were arrested on December 1, 2024, with Tarasov currently remaining at large. These efforts "serve as a testament to the power of international cooperation," Acting Special Agent in Charge of FBI Atlanta, Sean Burke, told the U.S. Attorney’s Office.
While the charges paint a disturbing picture of global cybercrime, we are reminded that indictments are not convictions. Per the U.S. Attorney’s Office, the accused are considered innocent until proven guilty beyond a reasonable doubt. The case is currently under the purview of the Federal Bureau of Investigation, with Assistant U.S. Attorney Samir Kaushal and Trial Attorney Ethan Cantor of the Justice Department’s Computer Crime and Intellectual Property Section, along with the National Cryptocurrency Enforcement Team, leading the prosecution.
