嗯，用户让我帮忙总结一篇文章的内容，控制在100个字以内，而且不需要用“文章内容总结”或者“这篇文章”这样的开头。直接写描述即可。首先，我需要仔细阅读这篇文章，抓住主要信息。 文章标题是“乌克兰人因参与Conti勒索软件被引渡至美国”。里面提到乌克兰人Oleksii Lytvynenko被从爱尔兰引渡到美国，指控他参与Conti勒索软件攻击。他是在2022年逃离乌克兰后被引渡的。他在美国法院出庭，面临指控，涉及部署Conti勒索软件，从美国受害者那里勒索超过50万美元。司法部的新闻稿详细说明了他如何与其他共谋者一起入侵计算机网络，加密数据，并要求赎金以恢复访问或避免泄露信息。他还管理被盗数据和赎金说明。他在爱尔兰被捕后继续进行网络犯罪活动。司法部的官员强调了勒索软件对美国公民和企业的威胁，并表示将继续在全球范围内追捕相关犯罪分子。FBI也提到他的全球部署行为，并强调了与爱尔兰的合作。他面临最高25年的监禁。 接下来，我需要将这些信息浓缩到100字以内。关键点包括：乌克兰人Oleksii Lytvynenko被引渡到美国，指控涉及Conti勒索软件攻击，金额超过50万美元，管理被盗数据和赎金说明，在爱尔兰被捕后继续犯罪活动，面临监禁。 所以总结起来应该是：乌克兰人Oleksii Lytvynenko被引渡至美国，因涉嫌参与Conti勒索软件攻击并从受害者处勒索超50万美元。他被指控管理被盗数据和赎金说明，并在被捕后继续犯罪活动。 </think> 乌克兰人Oleksii Lytvynenko被引渡至美国，因涉嫌参与Conti勒索软件攻击并从受害者处勒索超50万美元。他被指控管理被盗数据和赎金说明，并在被捕后继续犯罪活动。 2025-11-2 09:31:53 Author: securityaffairs.com(查看原文) 阅读量:11 收藏
Ukrainian extradited to US over Conti ransomware involvement

Ukrainian Oleksii Lytvynenko extradited from Ireland to US for alleged role in Conti ransomware after fleeing Ukraine in 2022.
Ukrainian national Oleksii Lytvynenko (43) extradited from Ireland to the US, faces charges for alleged involvement in Conti ransomware attacks after fleeing Ukraine in 2022.
The man appeared in a US court and was charged with deploying Conti ransomware that extorted over $500K from US victims.
“According to court documents, from in or around 2020 and continuing until about June 2022, Oleksii Oleksiyovych Lytvynenko, 43, of Cork, Ireland, conspired with others to deploy Conti ransomware to extort victims and steal their data.” reads the press release published by DoJ. “Court filings allege the conspirators hacked into victims’ computer networks, encrypted their data, and demanded a ransom to restore the victims’ access to their files and avoid public disclosure of the hacked information.”
Court filings allege Lytvynenko managed stolen Conti victim data and ransom notes. The Ukrainian national was arrested in Ireland in 2023 and continued cybercrime until his capture.
“The defendant allegedly participated in a conspiracy to extort approximately $150 million in ransomware payments responsible for defrauding victims in almost every U.S. state and from over two dozen countries worldwide,” said Acting Assistant Attorney General Matthew R. Galeotti of the Justice Department’s Criminal Division. “Ransomware is a significant threat to the safety, security, and prosperity of American citizens and business. The Department will continue to pursue ransomware actors all over the world in its efforts to hold them to account for the damage they have inflicted on victims.”
FBI’s Brett Leatherman added that Lytvynenko conspired to deploy Conti ransomware globally, extorting millions in crypto. His extradition highlights US–Ireland cooperation.
The man faces up to 25 years in prison if convicted of computer and wire fraud conspiracy. The FBI urges organizations to stay vigilant and promptly report ransomware incidents.
In September 2023, four other Conti conspirators were indicted in Tennessee. The FBI and U.S. Secret Service are investigating, with DOJ prosecutors handling the case.
