At about midnight on Monday March 18, 2019, one of the world’s largest aluminum producers, with smelting plants, factories and offices in 40 countries, noticed irregularities in its systems. Hours later, Norway-based Norsk Hydro confirmed it was suffering production stoppages in Europe and the US as it battled a major ransomware attack, forcing the company to switch to manual operations while it attempted to contain the issue.
Ransom was never paid, but the total cost of the attack was estimated to be around $52 million.
A few days later, 2 other US-based chemical companies, Hexion and Momentive, were also hit by cyber attacks and had to shut down IT systems to contain the incidents. The same encryption program called LockerGoga is thought to be behind all three attacks.
The attack had a tremendous impact on the production of aluminum worldwide.
This white paper is written as a guide to securing networks with Critical Infrastructure in order to prevent similar catastrophes from happening again.
