Norsk Hydro

Norsk Hydro, a global aluminum company, experienced a severe ransomware attack that ceased operations at some of its 170 plants. The breach impacted all 35,000 employees across 40 countries by locking files on thousands of servers and PCs. Initiated by an infected email from a customer, the breach allowed hackers to plant LockerGoga ransomware, leading to financial damages nearing $71 million. The company's transparency and decision not to pay the ransom were acclaimed by security experts, and they leaned on Microsoft's cybersecurity team for recovery and restoration.
