Norsk Hydro Ransomware Attack Is ‘Severe’ But All Too Common

Norsk Hydro ASA confirmed that a ransomware attack was behind production outages across the aluminum producer’s operations in Europe and the U.S.

The perpetrators are still unknown but the work is similar to other recent breaches. The Norwegian company, one of the world’s biggest aluminum producers, called the situation “quite severe,” and said it was still working to contain the effects. It couldn’t immediately detail how much output had been impacted but said the so-called potlines, which process molten aluminum and need to be kept running 24 hours a day, had switched to manual mode.
