O que aconteceu
Artem Aleksandrovych Stryzhak, a 35‑year‑old Ukrainian, was sentenced to 70 months in U.S. federal prison for acting as an affiliate of the Nefilim and Hive ransomware groups. From 2018‑2021 he financed and helped operate ransomware campaigns that encrypted and exfiltrated data from hospitals, government agencies, and large corporations across the United States, Canada, Australia, Norway, France, Switzerland, Germany, and the Netherlands. He received 20 % of ransom payments for access to custom Nefilim ransomware and decryption keys, and also participated in Hive attacks that affected a dentist office, law firms, and a healthcare provider during the COVID‑19 pandemic. The operation threatened to publish stolen data on dark‑web “Corporate Leaks” sites unless victims paid. The case was built on a guilty plea in December 2025, court documents, and coordinated arrests by U.S., Spanish, and international law‑enforcement agencies.
