Ukrainian-Russian Dual Citizen Pleads Guilty Over Running 15,000-Strong Money Mule Empire
Oleg Korniev, a 42-year-old dual Ukrainian-Russian citizen, pleaded guilty in a US court for leading Your Mule Cashout (YMCO), an international money laundering network that recruited over 15,000 unwitting US residents as money mules. The organisation laundered at least $10 million stolen from more than 750 US bank accounts, transferring funds primarily to Eastern European countries on behalf of cybercriminals in exchange for a cut of the proceeds. Korniev admitted to causing over $14.7 million in losses and faces between 2 and 50 years in prison, with four other YMCO members having already been sentenced to between 37 and 63 months.
Two Criminal Groups Are Quietly Gutting Brazil's Financial Infrastructure
A newly identified threat actor called **Slim Spider** has been conducting sophisticated attacks on Brazilian financial institutions since at least March 2026, targeting cryptocurrency assets and instant payment accounts linked to Brazil's Pix system. The group demonstrates advanced cloud security knowledge, using custom scripts to steal cloud credentials, enumerate secrets, and derive Ethereum wallet addresses, while deploying backdoors and malicious pipelines to maintain access and evade detection. Separately, another cybercrime group called **Breeze Comet** has been infiltrating Brazilian financial systems since 2024 to execute fraudulent transactions via Pix and other payment infrastructure, with both groups highlighting a broader shift from retail banking fraud toward direct attacks on core financial infrastructure.
