Russian hackers may have penetrated US electricity network and could turn off power, officials say

Russian hackers might have access to US electric utilities and could use them to cause blackouts across the country, according to new warnings. The group – who worked for a Russian state-sponsored group known as Dragonfly or Energetic Bear – gained access to networks last year and the campaign is probably continuing, according to a report in the Wall Street Journal. The hackers have already claimed "hundreds of victims", according to officials. But much of their most dangerous work might not actually have happened yet – with cyber attacks gaining access to the most critical parts of the US infrastructure and then sitting inside of it. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
