2019: Cyber-attack on Hydro

On March 19, 2019, Hydro was hit by an extensive cyber-attack affecting our entire global organization.


The business area Extruded Solutions suffered the most significant operational challenges and financial losses. Hydro’s other business areas – Bauxite & Alumina, Primary Metal, Rolled Products and Energy – were able to produce close to normal despite the attack, although based on work-intensive workarounds and manual procedures.

Hydro eventually resumed normal operations. During and after the attack, Hydro worked 24/7 with all available internal resources and in close cooperation with external expertise to resolve the situation​.

All PCs and servers across the company were reviewed, cleaned of any malware and safely restored, according to strict guidelines to ensure security and safety. Encrypted PCs and servers were rebuilt based on back-ups, our security team was reorganized to better detect and respond to cyber incidents.
