Ukrainian National Pleads Guilty in Major Ransomware Case

UPDATE: In a groundbreaking development, Artem Stryzhak, a Ukrainian national, has just pleaded guilty in a Brooklyn federal court to his role in a vast global ransomware conspiracy. This plea, which comes amid a surge in cybercrime, underscores the urgency of addressing threats to digital security.

JUST IN: Stryzhak admitted to conspiring to commit fraud and related computer extortion offenses involving the notorious Nefilim ransomware. His actions have been linked to a series of attacks targeting large corporations primarily in the United States, Canada, and Australia.

Arrested in Spain in June 2024 and extradited to the U.S. on April 30, Stryzhak now faces up to 10 years in prison. His accomplice, Volodymyr Tymoshchuk, remains at large, with the U.S. Department of State offering a staggering $11 million reward for information leading to his capture.

Court documents reveal that Stryzhak and his associates employed sophisticated techniques to infiltrate corporate networks, encrypting vital digital systems, and demanding ransom payments. They threatened to publish stolen data on “Corporate Leaks” sites if their ransom demands were not met, leaving businesses vulnerable and at risk.

U.S. Attorney Joseph Nocella praised the collaboration between international and federal law enforcement agencies, including the FBI’s New York Field Office and Spanish authorities, which led to Stryzhak’s arrest. He emphasized the Office’s dedication to holding cybercriminals accountable for their actions.

The search for Tymoshchuk continues, with officials identifying him as a key player in the Nefilim ransomware operations. Christopher J.S. Johnson, Special Agent in Charge of the FBI Springfield, stated that the bureau is committed to tracing digital activity across networks and borders to bring those responsible for cybercrimes to justice.

The case, overseen by the Office’s National Security and Cybercrime Section, highlights the increasing focus on cyber threats in the digital age. Assistant U.S. Attorneys Alexander F. Mindlin and Ellen H. Sise, along with Trial Attorney Brian Mund, are leading the prosecution efforts.

Members of the public are urged to report any information regarding Tymoshchuk or related individuals to the FBI at +1-917-242-1407 or via email at [email protected]. More information about the State Department’s reward offer can be found on its official website, and tips can also be submitted to any local FBI office or U.S. embassy abroad.

As the investigation develops, this case serves as a stark reminder of the growing threat posed by ransomware and the ongoing efforts to combat cybercrime on a global scale. Stay tuned for further updates on this urgent situation.
