Russian top oil producer Rosneft has reported "a powerful hacker attack" on its servers.
"A powerful hacker attack has been carried out on the company's servers, and we hope that this has nothing to do with the current judicial procedures. The company has appealed to the law enforcement agencies on the fact of cyberattacks," Rosneft said in a statement published on its Twitter page.
The Arbitration Court of the republic of Bashkortostan is considering the lawsuit filed by Rosneft and Bashneft against Sistema Holding and its subsidiary Sistema-Invest on the recovery of 170.6 billion rubles ($2.9 bln) of losses suffered by Bashneft in the result of the reorganization in 2014
