Norsk Hydro

Norsk Hydro, one of the world's largest aluminum companies, faced a severe cyberattack in March, ultimately affecting all 35,000 employees across 40 countries. The attack, initiated by an infected email from a trusted customer, caused production lines to halt and forced some facilities to switch to manual operations. The financial impact approached $71 million. Despite the scale of the attack, the company chose not to pay the ransom, instead opting to restore data from backup servers and seek assistance from Microsoft's cybersecurity team. Norsk Hydro's transparent response to the breach was praised for helping to expose the tactics of cyber criminals and possibly preventing similar future threats.
