Norsk Hydro Production lines stopped

September 15, 2020


Production lines had stopped at some of its 170 plants.

The ransomware LockerGoga blocked the company’s systems, forcing a switch to manual operations and workarounds. The Extruded Solutions unit, which makes components for car manufacturing, construction and other industries, reduced its output by 50%. Administrative systems, such as reporting, billing and invoicing, suffered delays. It took Norsk Hydro several weeks to bring operations back to normal.
