Ukraine cyber-attack: Russia to blame for hack, says Kyiv

The Ukrainian government has accused Russia of being behind Friday’s cyber-attack on dozens of official websites.

About 70 government websites were temporarily down, in the largest such attack on Ukraine in four years.

Before the sites went offline, a message appeared warning Ukrainians to “prepare for the worst”. Access to most of the sites was restored within hours.

The US and Nato condemned the attack and have offered support to Ukraine. Russia has not commented on the hack.
