Oleksandr Tkachuk, chief of staff at Ukraine's Security Service, SBU, said on Wednesday that the attacks were orchestrated by the Russian security service with help from criminal hackers, and looked like they were designed by the same people who created malware known as "BlackEnergy," Radio Liberty reports. Ukraine blamed hackers using BlackEnergy for knocking out part of Kyiv's power grid in December 2015, and for attacks last year on the Defence and Finance ministries and the State Treasury. "Russian hackers and infobots become an important tool of the aggression against our country," Tkachuk said. The latest attacks employed a mechanism dubbed "Telebots" to infect computers that control infrastructure, he said. Slovakian cybersecurity firm ESET said it believes the Telebots evolved from the BlackEnergy hacking effort
