Ukraine will investigate a suspected computer malware attack on its energy grid, the energy ministry said on last week, an incident the country's secret service has blamed on Russia. The 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.
According to a Reuters report, the Ukrainian Security Service SBU blamed Russia, which has not so far commented on the allegation.
The energy ministry has since set up a special commission to investigate what happened. Despite the blackout, the Ukrainian Security Service had managed to thwart the malware. The malware had failed to kick in as intended and was neutralized, the report said. The region would have faced a much longer blackout if it had worked, a spokeswoman for the security service said.
