Norsk Hydro's operations restricted in cyber attack aftermath

Norsk Hydro, one of the world's largest aluminium producers, said one of its key units is operating at only 50 per cent of capacity following a cyber attack on the firm earlier this week. "Extruded Solutions is working hard to enable further restarts during the coming days, which would allow for continued deliveries to customers," Hydro said. The company's extrusion business transform aluminium ingots into components for car-makers, builders and other industries.
