The scope of the defendant’s conduct
On 27 October 2026, a federal court in Brooklyn sentenced Artem Stryzhak to 70 months in prison. The US Justice Department said he pleaded guilty in December 2025 to a conspiracy involving computer fraud and extortion.
Prosecutors described his involvement in attacks using Nefilim and Hive ransomware. Such software locks data and is used to demand ransom; victims in his episodes included healthcare and legal organisations.
Stryzhak was arrested in Spain in June 2024 and extradited to the United States in April 2025. The total attacks and losses attributed to the wider Hive group cannot automatically be assigned to this individual defendant.
