The company has concluded a number of metal extrusion plants, which transform aluminum ingots into components for the auto-makers, builders, and other industries, while the giant smelters in countries such as Norway, Qatar and Brazil were operated by hand.

The attack started on Monday evening and escalated overnight, hitting the water power of the IT systems for most of its activities, and forcing employees to the problem of updates through social media.

The Norwegian National Security Authority (NNSA), the government agency in charge of cybersecurity, said that the attack of a virus known as LockerGoga, a relatively new strain of so-called ransomware that encrypts files and demands payment to unlock them.

The quoting of a message that is sent by the NNSA, public broadcaster NRK said on its website the hackers had demanded ransom from Hydro to stop the attack, but the company has not confirmed this.

The malware is not widely used by cyber gangs, researchers said, but is linked to an attack on the French engineering consultancy Altran Technologies in January.

“Hydro Is working to contain and neutralize the attack, but does not yet know the full extent of the situation,” the company said in a statement.

It added that the attack did not affect the safety of its staff, and it was still too early to assess the impact on the customers.

News of the attack pushed aluminium prices to as much as 1.2 percent to a three-month high of $1,944 a ton in the beginning of trading on the London Metal Exchange, before giving up some gains to trade at $1,938 by 1253 GMT.

The event was a rare case of an attack on industrial activities in Norway. The last publicly acknowledged cyber attack in the Scandinavian country was on the Visma software company, when hackers allegedly working on behalf of the Chinese intelligence violated its network to steal secrets from its customers.

Pyongyang denies the allegations.

Hydro products across the aluminium value chain, of the refinement of alumina raw material via metal rods to custom-made parts are used in cars and construction.

“Some extrusion plants that are easy to stop and start have chosen to temporarily shut down the production,” said Hydro spokesperson.

The company’s hydro-electric power stations were running as normal on isolated IT systems are not affected by the outage.

Norsk Hydro’s website page is not available on Tuesday, although some of the web pages that belong to the subsidiaries can still be used. The company gave updates about the situation on her Facebook page.
