Artem Stryzhak, a Ukrainian citizen, has been indicted on charges of conspiracy, extortion, and fraud involving the Nefilim ransomware. The indictment stems from his role in an international operation that targeted high-revenue U.S. companies, stealing data and demanding ransom for its return. If payments weren't received, the stolen information was leaked online. Following his arrest in Spain in June 2024, Stryzhak was extradited to the U.S. on April 30, 2025. Authorities emphasize that international cyber-criminals can be prosecuted, regardless of their location, highlighting the importance of international law enforcement collaboration.
As alleged, the defendant was part of an international ransomware scheme in which he conspired to target high-revenue companies in the United States, steal data, and hold data hostage in exchange for payment.
The criminals who carry out these malicious cyber-attacks often do so from abroad in the belief that American justice cannot reach them. The extradition of the defendant and today's charges prove that they are wrong.
The FBI has long recognized that combating international ransomware schemes requires strong partnerships. The successful extradition of the defendant is a significant achievement in that ongoing collaboration.
I want to especially thank the Justice Department's Office of International Affairs, Computer Crime and Intellectual Property Section, and the Government of Spain for their crucial assistance.
