Extradited Ukrainian Man Admits Role in Conti Ransomware Attacks

A Ukrainian national extradited from Ireland pleaded guilty in the United States for his role in the Conti ransomware operation; prosecutors say Conti operated from 2020–2022, compromising over 1,000 systems across dozens of countries and extracting at least $150 million in ransom payments. The defendant admitted to coding a loader and stealing data from multiple victims, and faces sentencing in September 2026 as part of the FBI’s Operation Riptide targeting cybercrime infrastructure and actors.
