Ukrainian extradited from Ireland on Conti ransomware charges, could face up to 25 years in prison for his role in the cybercrime operation.
Oleksii Oleksiyovych Lytvynenko, a Ukrainian national believed to be a member of Conti ransomware operation, has been extradited from Ireland to the United States. Lytvynenko was accused of controlling stolen data and participating in sending ransom notes as part of the group's double extortion attacks between 2020 and June 2022. The investigation uncovered a complex web of cybercrime schemes linked to Lytvynenko, including wire fraud conspiracy and computer fraud conspiracy charges. The Conti ransomware operation has been linked to over 1,000 victims worldwide and received ransom payments exceeding $150 million as of January 2022. The extradition marks an important milestone in dismantling and prosecuting individuals linked to the Conti operation.
In a significant development that has sent shockwaves through the cybersecurity community, a Ukrainian national believed to be a member of the notorious Conti ransomware operation has been extradited from Ireland to the United States. The extradition of Oleksii Oleksiyovych Lytvynenko, a 43-year-old individual, marks a major breakthrough in the ongoing investigation into the Conti group's alleged involvement in various cybercrimes.
According to sources within the FBI's Cyber Division, Lytvynenko was accused of controlling data stolen from numerous Conti victims and participating in sending ransom notes as part of the group's double extortion attacks between 2020 and June 2022. The investigation, which has spanned several years, uncovered a complex web of cybercrime schemes and operations linked to Lytvynenko.
The Irish national police (An Garda Síochána) had arrested Lytvynenko in July 2023 at the request of the United States, as part of an ongoing effort to dismantle the Conti ransomware operation. An Irish court subsequently detained the defendant while awaiting extradition proceedings, which concluded this month.
Court documents obtained by our sources reveal that Lytvynenko was involved in various other cybercrime schemes prior to his arrest in Ireland in 2023, in addition to his involvement with Conti. These allegations include wire fraud conspiracy and computer fraud conspiracy charges, which could potentially result in a sentence of up to 20 years in prison for the first count and 5 years for the second.
The Conti ransomware operation, which was launched by the Russian-based cybercrime gang in 2020, has been the subject of intense scrutiny over the past few years. The group initially emerged as a replacement for the Ryuk ransomware group but eventually evolved into a sophisticated cybercrime syndicate, assuming control over multiple malware operations, including TrickBot and BazarBackdoor.
While the Conti brand appears to have been shut down, its members have fragmented into smaller cells, infiltrating or taking over other ransomware and cybercrime operations. According to reports from law enforcement agencies, this has resulted in the emergence of new threat actors, including BlackCat, Black Basta, ZEON, Hello Kitty, Hive, AvosLocker, Quantum, BlackByte, Karakurt, and the Bazarcall collective.
The Department of Justice has linked the Conti ransomware operation to over 1,000 victims worldwide and received ransom payments exceeding $150 million as of January 2022. Furthermore, FBI estimates suggest that Conti's malware was used in more critical infrastructure attacks than any other ransomware variant.
Assistant Director Brett Leatherman of the FBI's Cyber Division described Lytvynenko as a "key player" in the Conti operation, stating that he conspired to deploy the group's ransomware against victims in the United States and across the globe, extorting millions in cryptocurrency while amassing a trove of stolen data. The investigation also revealed instances where the conspirators allegedly extorted more than $500,000 in cryptocurrency from two victims in the Middle District of Tennessee and published information stolen from a third victim in that district.
The U.S. and United Kingdom have also taken steps to target individuals associated with the TrickBot and Conti ransomware operations, sanctioning nine Russian nationals for their involvement in attacks against over 900 victims worldwide. Seven other members were sanctioned in February 2023 following the leak of a massive trove of personal information and internal conversations belonging to Conti and TrickBot members.
In May 2025, German authorities announced that they had identified the leader of the Trickbot and Conti cybercrime gangs as Vitaly Nikolaevich Kovalev, using the alias "Stern." Kovalev was described as a 36-year-old Russian national who played a key role in orchestrating the group's activities.
The extradition of Lytvynenko marks an important milestone in the ongoing efforts to dismantle and prosecute individuals linked to the Conti ransomware operation. As the global cybersecurity landscape continues to evolve, law enforcement agencies must remain vigilant in their pursuit of those responsible for these complex cybercrimes.
