Over the past week, Ukraine's Finance and Defense ministries and State Treasury said their websites had been temporarily downed by attacks aimed at disrupting their operations, according to Reuters.
"These attacks were planned in advance and coordinated from a center based in the Russian Federation," the secretary of Ukraine's National Security and Defense Council, Oleksander Turchynov, said.
At the end of 2015, the council blamed Russia for a cyber attack on its power grid that left part of western Ukraine temporarily without electricity.

Bratislava-based computer security company ESET said it believed the recent attacks on the ministries were attempted "cybersabotage" and likely carried out by the same group that targeted Ukraine's power grid last year.
