The US government officially established that power cuts in Ukraine in December 2015 were caused by cyber culprits, informed “Holos Ameryky” (“Amercica’s Voice”).
Power cuts that affected 225 thousand Ukrainians were caused by hacker attacks, it is said in the report of US Department of Homeland Security based on interviews with representatives of 6 Ukrainian organizations affected by power cuts. However, American experts were unable to verify technical proof independently.
US Department of Homeland Security doesn’t report who stands behind these cyber attacks. However, American cyber company iSight Partners and others companies link the incident to a Russian hacker group known as Sandworm.
Some security experts in the USA have strongly criticized conclusions made by the Department.
“Had they revealed this information two months ago, it would’ve been useful, - said Robert Lee, Managing Director for cyber security at Dragos Security, - now, however, they are telling things we already know”.
