A dual Russian and Ukrainian citizen has pleaded guilty in the United States to running a global money laundering operation that used more than 15,000 people as money mules to move at least $10 million in stolen bank funds. Oleg Korniev, 42, admitted he led Your Mule Cashout (YMCO), which allegedly helped cybercriminals conceal their tracks and transfer money taken from more than 750 American bank accounts to destinations outside the United States. Prosecutors said YMCO combined an online infrastructure with a nationwide pool of US-based money mules. People in the scheme were allegedly deceived into believing they were carrying out legitimate financial transactions for legitimate businesses, while YMCO collected commissions on the transfers. Korniev’s plea agreement says the operation funneled proceeds mainly to Eastern European countries and caused losses exceeding $14.7 million. He also admitted intending to launder more than $9.7 million obtained from cybercriminals and actually laundering at least $7 million. As part of the guilty plea, Korniev agreed to full restitution to victims and forfeit rights to funds seized when he was arrested in Georgia. His sentencing date has not been set, with a potential prison term of 2 to 50 years. Four other defendants in the YMCO case were previously arrested abroad and extradited to the United States. They pleaded guilty to conspiring to commit money laundering and received prison sentences ranging from 37 to 63 months. The FBI led the investigation with the Justice Department’s Office of International Affairs and Georgian law enforcement authorities, including the prosecutor’s office. Korniev is currently awaiting sentencing after pleading guilty in federal court.
