Norsk Hydro

In March, Norsk Hydro, one of the world's largest aluminum companies, experienced a significant cyberattack that shut down production lines across its 170 plants, and led to a switch from computer to manual operations at some of its facilities. The attackers used a malware called 'LockerGoga' to encrypt files on thousands of servers and PCs, affecting all 35,000 employees in 40 countries. The financial impact of the attack reached approximately $71 million. The breach occurred due to an employee opening an infected email, leading to a severe compromise of the company's IT infrastructure. Despite the extensive damage, Norsk Hydro chose not to pay the ransom and instead worked on restoring their data from backups and improving their cybersecurity posture with the help of Microsoft's cybersecurity team.
