KYIV (Reuters) - Ukraine's State Security Service (SBU) said on Tuesday it had prevented a large-scale cyber attack by Russian hackers targeting classified government data.
The SBU said the aim was to "get access to classified data of the highest institutions of state power of Ukraine" and accused the Russian Federal Security Service (FSB) of being behind the hackers who it said had carried the attack.
Kyiv has previously accused Moscow of orchestrating large cyber attacks as part of a "hybrid war" against Ukraine, but Russia denies this. The FSB did not immediately comment on the latest accusation.
