“We identified a weakness in the platform of one of our suppliers. That weakness has now been shut,” Erik Hope, head of the government agency in charge of providing services to ministries, told a news conference.
The attack was identified due to “unusual” traffic on the supplier’s platform, Hope said, declining to provide specifics. It was uncovered on July 12 and was being investigated by police.
“It is too early to say who is back this and what is the extent of the impact (of the attack),” he said.
Norway is Europe’s largest gas supplier after a drop in Russian gas flows and Western Europe’s largest oil exporter.
The PM’s office as well as the foreign, defence, justice ministries were not affected because they use a different IT platform, said Hope.
