A federal grand jury in the Northern District of Georgia returned an indictment on Jan. 7 charging three Russian nationals for their involvement in operating the cryptocurrency mixing services Blender.io and Sinbad.io. Roman Vitalyevich Ostapenko and Alexander Evgenievich Oleynik were arrested on Dec. 1, 2024, roughly a year after Sinbad.io’s online infrastructure was seized as part of a coordinated law enforcement action among the Netherlands’ Financial Intelligence and Investigative Service, Finland’s National Bureau of Investigation, and the FBI. The third defendant, Anton Vyachlavovich Tarasov, remains at large.
