Norsk Hydro, one of the world's largest producers of aluminum, was battling on Tuesday to contain a cyberattack which hit parts of its production, sending its shares lower and aluminum prices higher. The attack, which began on Monday evening and escalated overnight, affected the company's IT systems for most of its activities. Alumina refinery Alunorte in northern Brazil is owned by Norwegian company Norsk Hydro. "Some extrusion plants that are easy to stop and start have chosen to temporarily shut production," said a Hydro spokesman. Norsk Hydro's main website page was unavailable on Tuesday, although some of the web pages belonging to subsidiaries could still be accessed.
