The hacker attack against the servers of the National Revenue Agency was discussed at the extraordinary sitting of the Security Council with the Council of Ministers. The information sent from a Russian domain to the Bulgarian media coincides with the information available at the servers of the National Revenue Agency and confirms that there was an illegal access to the database, Bulgaria’s Minister of Interior Mladen Marinov said. Bulgaria’s Minister of Finance Vladislav Goranov pointed out that the hacker attack affected 3% of the database of the National Revenue Agency. The hacker attack was made through an online service for refund of value added tax paid abroad. This vulnerability has already been eliminated through the temporary suspension of the service until the information security of the system is restored, the National Revenue Agency announced.
