Norsk Hydro, one of the world's largest aluminum companies, faced a severe cyberattack that halted production lines at some of its 170 plants and pushed other facilities to switch from computer to manual operations. The incident, caused by LockerGoga ransomware, began with an infected email and eventually affected all 35,000 employees across 40 countries, locking files on thousands of servers and PCs. The financial impact neared $71 million. Despite the crisis, Norsk Hydro refused to pay the ransom, opting for transparency and collaborating with Microsoft's cybersecurity team to restore operations. This approach, contrasting the typical secrecy following such breaches, earned global commendation.
