The Kremlin has consistently denied the accusations.
The President of Bulgaria Rosen Asenov Plevneliev said that Russia is trying to divide and destabilize Europe through cyber attacks.
According to Plevneliev, the Kremlin is trying to influence the policy of his country and other European countries, the financing of political parties and spreading propaganda.
According to the native of the GERB party, last year, the website of the CEC of Bulgaria and a number of government pages were attacked by hackers related to the same group as the organizers of the attacks on the website of the American Democratic party on the eve of elections.
But the Kremlin has consistently denied the accusations.
