Conti Developer Sentenced to Four Years in U.S. Prison

Overview

• A U.S. court sentenced Ukrainian national Oleksii Oleksiyovych Lytvynenko to four years in prison on Thursday, Sept. 10, 2026, after he pleaded guilty in June to conspiracy to commit wire fraud tied to Conti ransomware.
• Prosecutors say Lytvynenko joined Conti in September 2021 and worked as both an intruder and developer who coded a malware loader and stored stolen files from 12 victims.
• Authorities attribute about $634,000 in Bitcoin extorted from two Tennessee victims to Lytvynenko and his co-conspirators and say they leaked data from another Tennessee victim after a refused $3 million ransom demand.
• His arrest came in County Cork, Ireland, in July 2023 and he was extradited to the United States in October 2025, a case handled with help from the FBI, U.S. Secret Service, Homeland Security Investigations and Irish law enforcement.
• The sentence closes one chapter of the long-running Conti campaign that hit more than 1,000 victims and drew an estimated $150 million in payouts while underscoring law enforcement efforts to pursue remaining members and successor ransomware groups.
