A 42-year-old dual citizen of Ukraine and Russia, Oleg Korniev, pleads guilty to running an international money laundering operation tied to cybercrime. Prosecutors say he served as a principal of Your Mule Cashout (YMCO), which from 2007 to 2014 set up and managed a network of money mules in the United States and Europe.

According to reporting, the scheme involved large numbers of participants—one outlet describes up to 15,000 money mules—and was used to launder proceeds for cybercriminals worldwide. The U.S. Justice Department says the operation helped move around $10 million connected to funds stolen from U.S. bank accounts. Outlets also describe the network as sophisticated, using mule-based transfers to obscure the origin and destination of illicit funds. The sources focus on the scale of the operation and the defendant’s role, citing his guilty plea as the key development.
