A newly discovered hacking group has attacked transportation and logistics companies in Ukraine and Poland with a novel kind of ransomware<\/a>, Microsoft<\/a> said in a blog post. 一种新发现的黑客组织攻击运输和物流公司在乌克兰和波兰的小说ransomware,微软在一篇博客文章中说。
The attackers targeted a wide range of systems within an hour on Tuesday, Microsoft said, adding that it hadn't been able to link the attacks to any known group yet.
Notably, however, researchers found that the hacks closely mirrored earlier attacks by a Russian government-linked cyber team that had disrupted Ukraine government agencies.
Ukraine has been the target of numerous cyberattacks<\/a> by Russia since the start of the conflict in late February, according to western security researchers and senior government officials.
The Russian Embassy in Washington did not immediately respond to a request for comment, and neither did the cybersecurity agencies of Ukraine or Poland.
Victims of the new ransomware, named \"Prestige,\" overlap with those of another data-shredding cyberattack that involved the \"FoxLoad,\" or \"HermeticWiper\" malware, Microsoft said.
That attack hit hundreds of computers in Ukraine, Lithuania, and Latvia at the beginning of the Russian invasion of Ukraine.
\"Prestige\" ransomware works by encrypting a victims' data and leaving a ransom note that says the data can only be unlocked with the purchase of a decryption tool, Microsoft said.
In several cases, the researchers noted that the hackers<\/a> had gained administrator control of the victims' systems ahead of deploying the ransomware, suggesting they had stolen their credentials earlier and were waiting for the right moment.
\"The enterprise-wide deployment of ransomware is not common in Ukraine, and this activity was not connected to any of the 94 currently active ransomware activity groups that Microsoft tracks,\" the researchers said.

袭击者的目标广泛的系统在一个小时内周二,微软还说,它没有能够链接任何已知的攻击群。
然而,值得注意的是,研究人员发现,黑客密切反映早些时候袭击俄罗斯政府网络团队已经扰乱了乌克兰政府机构。
乌克兰已经被无数的目标网络攻击由俄罗斯开始以来的冲突在2月底,根据西方安全研究人员和政府高级官员。
新ransomware的受害者,命名为“威望”,重叠与另一个data-shredding网络攻击,涉及“FoxLoad”或“HermeticWiper”的恶意软件,微软说。
攻击了成百上千的计算机在乌克兰、立陶宛和拉脱维亚在乌克兰的俄罗斯入侵的开始。
“威望”ransomware通过加密受害者的工作数据和离开赎金注意说购买的数据只能解锁一个解密工具,微软说。
在一些情况下,研究人员指出黑客获得管理员控制受害者的系统部署ransomware之前,建议他们偷了他们的凭证,等待合适的时机。
”的企业级部署在乌克兰ransomware并不常见,这个活动并没有连接到任何现有的94活跃ransomware活动团体,微软,”研究人员说。
