Ukraine to investigate suspected computer attack on energy grid

KIEV (Reuters) - Ukraine will investigate a suspected computer malware attack on its energy grid, the energy ministry said on Thursday, an incident the country's secret service has blamed on Russia.

A power company in western Ukraine, Prykarpattyaoblenergo, said on Dec. 23 that a swath of the area it serves had been left without energy, including the regional capital Ivano-Frankivsk, due to "interference" in the work of the system.
