The Security Service of Ukraine (SBU) said on Tuesday it had prevented a large-scale cyberattack by Russian hackers targeting classified government data.
The SBU said the goal was “to access classified data from the highest institutions of Ukraine’s state power” and accused Russia’s Federal Security Service (FSB) of being behind the “hackers.” who he said had carried out the attack.
kyiv has previously accused Moscow of orchestrating major cyberattacks as part of a “hybrid war” against Ukraine, but Russia denies this. The FSB did not immediately comment on the latest allegation.
The SBU did not say if any damage had been caused in the latest incident.
In February, Ukrainian cyber authorities accused unidentified Russian networks on the Internet of attacking Ukrainian defense and security websites and attempting to spread malicious documents through a web-based system.
Ukraine and Russia have been at odds since Russia’s annexation of Crimea in 2014 and involvement in a conflict in eastern Ukraine that kyiv says has killed 14,000 people.
