The Croatian Foreign and European Affairs Ministry has discovered that during the term of the previous government their shared communication network had suffered a cyber attack that enabled a hacker to penetrate the the ministry's computer system, but not a single strategic document has been compromised, Foreign Minister Davor Ivo Stier told Hina on Friday.
"The attack did not take place during the term of this government, the hacker attack took place during the term of Minister Miro Kovac," Stier said.
Asked if the media information that hackers failed to reach important documents were true, Stier said that according to a report he had received "not a single document of strategic important for Croatia has been compromised."
Stier ordered additional security measures for the ministry computer system to prevent similar attacks in the future.
The Jutarnji List daily said it was unknown who was behind the attack, but some of the sources suspected that the attack was launched by Russian hackers, adding however that the attack had nothing to do with Croatian Prime Minister Andrej Plenkovic's recent visit to Ukraine for which Russian criticised Croatia.
Asked to comment if the cyber attack could have anything to do with Plenkovic's visit to Ukraine, Stier said the attack took place when Plenkovic was not even the prime minister.
