A cyber-attack on Hydro, the Norwegian aluminium company, has cost it at least 300 million Norwegian kroner (£25.6m). Hydro, which employs 35,000 people in 40 countries, was hit by malware last week.
Although the company is slowly bringing affected systems back online, the “preliminary” cost of the incident had been about 300-350 million kroner. Most of those losses had been in its Extruded Solutions division, which makes aluminium facades, Hydro said.
Overall production in this division was down 20-30%. One of Hydro’s business units, which makes doors and windows, was “at a standstill”. In addition, machines normally automatically controlled by computers were being operated manually at some factories. Despite this, Hydro has been praised by cyber-security experts for its transparency.
In a Tweet, Dale Paterson, who advises commercial companies on cyber-security issues, praised Hydro’s latest update as “tremendous” for detailing the business impact of the attack.
