Ukrainian National Sentenced for Role in Conti Ransomware Operation Oleksii Oleksiyovych Lytvynenko, a 44-year-old Ukrainian national, was sentenced to four years in U.S. prison for conspiracy to commit wire fraud related to the Conti ransomware operation. The Conti group infected over 1,000 victims worldwide, generating more than $150 million in ransom payments from 2020 to 2022. Lytvynenko was arrested in Ireland in July 2023 and extradited to the U.S. in 2025. He pleaded guilty in June 2026, admitting to developing malware and possessing stolen data from at least 12 victims. The Conti ransomware targeted various sectors, including critical infrastructure, schools, and businesses across 47 U.S. states and 31 countries. Despite the group's shutdown in 2022, Lytvynenko continued engaging in ransomware activities until his arrest. The case highlights ongoing international efforts to combat cybercrime. 20 sources 44
