After most Norwegian websites and services had major problems on Wednesday, a Russian hacker group has taken on the cyber attack.

It is also said that they will attack the police and the Norwegian Migration Board.

- They should not make money and they should not steal information.

They are just looking to sabotage, says Audun Jøsang, professor of information security at the University of Oslo.



- The reason lies in the political landscape, that Sweden and Norway have agreed with NATO and Norway should be punished for that, Jens Stoltenberg is Norwegian and the label for NATO, he continues.
