2016-2017 Wired technology writer Andy Greenberg, in reviewing the history of the cyberattacks, said that the attacks came from a Russian military hacker group called "Sandworm". Greenberg asserted that Sandworm was behind the 2016 blackouts in Kyiv, among other events. The group had been focusing on hacking into Ukraine's financial sector, and sometime in early 2017, had been able to gain access to M.E. Doc's update servers, so that it could be used maliciously to send out the cyberattack in June 2017.[19]
