Ukraine Probing Cyber Attack on Power Grid

Ukraine will investigate a suspected cyber attack on its power grid, the energy ministry said, 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.
