A serial ransomware crook has been sentenced to 70 months in prison for his role in the Nefilim and Hive ransomware gangs. This case highlights the dangers of cybercrime and the importance of international cooperation in bringing perpetrators to justice.
Artem Stryzhak, a serial ransomware crook, has been sentenced to 70 months in prison for his role in Nefilim and Hive ransomware gangs. Stryzhak's involvement with Nefilim began in June 2021, targeting companies in the US, Canada, and Australia. He attacked approximately seven victims as an affiliate of Nefilim and around 1,500 victims as an affiliate of Hive. Stryzhak's actions were part of a larger trend of ransomware attacks targeting healthcare facilities during the COVID-19 pandemic. The FBI described Stryzhak as a "prolific cybercriminal" responsible for over $100 million in victim damages. Rewards totaling up to $11 million are available for information about alleged Nefilim operator Volodymyr Tymoshchuk and other key ransomware suspects. The case highlights the need for increased awareness and cooperation between law enforcement agencies and private companies to combat ransomware attacks.
Artem Stryzhak, a serial ransomware crook, has been sentenced to 70 months in prison for his role as an affiliate of the Nefilim and Hive ransomware gangs. This case highlights the dangers of cybercrime and the importance of international cooperation in bringing perpetrators to justice.
Stryzhak's involvement with Nefilim began in or around June 2021, while he was living in Barcelona, Spain. He joined forces with the alleged Nefilim boss, Volodymyr Tymoshchuk, who remains at large. Tymoshchuk told Stryzhak that his preference was for attacks to target companies based in the US, Canada, and Australia that turn over more than $100 million annually. This guidance was soon tweaked to encourage targeting companies in the same regions with more than $200 million in annual revenue.
As an affiliate of Nefilim, Stryzhak used the gang's platform to attack approximately seven victims. He also signed up to the Hive ransomware operation as one of its earliest affiliates and used its platform to attack around 1,500 victims worldwide between June 2021 and January 2023. Hive's victims included a law firm and an Ohio hospital, which paid approximately $1.7 million in Bitcoin after the gang initially demanded $2 million during the COVID-19 pandemic.
Stryzhak's actions were part of a larger trend of ransomware attacks targeting healthcare facilities during the COVID-19 pandemic. The Nefilim and Hive gangs were also responsible for battering Costa Rica in 2022.
The FBI's cyber branch described Stryzhak as a "prolific cybercriminal" who played a role in groups that were responsible for more than $100 million in victim damages. The sentence reflects the seriousness of Stryzhak's crimes and demonstrates the FBI's global reach and extensive network of international partners.
The Justice Department took the opportunity to remind the public that rewards totaling up to $11 million are available for qualifying information about alleged Nefilim operator Volodymyr Tymoshchuk and other key ransomware suspects.
This case highlights the need for increased awareness and cooperation between law enforcement agencies and private companies to combat the growing threat of ransomware attacks.
