Romanian national Daniel Christian Hulea, 30, was sentenced to 20 years in prison for his role in NetWalker ransomware attacks, pleading guilty to fraud charges in June.
Hulea admitted to extorting 1,595 bitcoin (~$21.5M) in ransom payments from organizations worldwide, including healthcare during COVID-19.
Romanian authorities arrested Hulea in July 2023 and extradited him to the U.S. under the U.S.-Romania extradition treaty.
The NetWalker ransomware group has targeted various victims, including K-Electric, Dirección Nacional de Migraciones, and the University of California San Francisco.
