A Ukrainian national pleaded guilty in a US court to his role in the notorious Conti ransomware group, the Department of Justice announced.
The man, Oleksii Oleksiyovych Lytvynenko, 44, of Cork, Ireland, was arrested in Ireland in 2023 and was extradited to the US in October 2025 to face Conti-related charges.
Lytvynenko admitted in court to joining the Conti operation in September 2021 and working on the development of a malware loader for the group. He also admitted to possessing data from 12 victims, including eight in the US.
Authorities in the US believe that the Ukrainian national continued to engage in cybercriminal activities after the Conti operation shut down.
Lytvynenko pleaded guilty to wire fraud conspiracy and faces up to 20 years in prison. He is scheduled for sentencing on September 10, 2026.
