Kyiv power cut "was cyberattack" - research
A power cut that hit part of the Ukrainian capital, Kyiv, in December has been judged a cyberattack by researchers investigating the incident, according to BBC.
The cyber-security company Information Systems Security Partners (ISSP) has linked the blackout, which lasted just over an hour and started just before midnight on December 17, to a hack and blackout in 2015 that affected 225,000, BBC reports.
It also said a series of other recent attacks in Ukraine were connected.
The 2016 power cut had amounted to a loss of about one-fifth of Kyiv's power consumption at that time of night, national energy company Ukrenergo said at the time.

Ukraine has said Russia directed thousands of cyber attacks towards it in the final months of 2016.
ISSP, a Ukrainian company investigating the incidents on behalf of Ukrenergo, said that both the 2015 and 2016 attacks were connected, along with a series of hacks on other state institutions this December, including the national railway system, several government ministries and a national pension fund.

He also said different criminal groups had worked together, and seemed to be testing techniques that could be used elsewhere in the world for sabotage.
Marina Krotofil, a researcher for Honeywell Industrial Cyber Security Lab, which also assisted the investigation, added that "the December 2016 attack was not meant to have any lasting dramatic consequences".
