Norsk Hydro, a Norwegian aluminium and renewable energy company, was subject to a ransomware attack on Tuesday, 19 March 2019.

The company confirmed the attack in a statement on their website: ‘Hydro became victim of an extensive cyber-attack in the early hours of Tuesday (CET), impacting operations in several of the company’s business areas.’

‘IT-systems in most business areas are impacted and Hydro is switching to manual operations as far as possible.’

The full extent of the situation is not yet known, however, Hydro is working with Norwegian authorities to contain and neutralize the attack.

Such attacks are not contained to just large companies like Norsk Hydro. In 2017, the Australian Cadbury chocolate factory in Tasmania was impacted after the global attack of the NotPetya Ransomware. NotPetya famously crippled AP Moller-Maersk, a large Denmark-based oil and shipping company resulting in $870 million (US) in losses.

Be ransom aware

Ransomware is a type of malware or virus which denies users the ability to access their computer files or systems until a ransom is paid.

Computers and systems can become infected when users visit unsafe or suspicious websites, open emails or files from someone unknown, or clicking on ‘malicious’ links in social media and peer-to-peer networks.

Paying the ransom does not guarantee files will be restored, and may leave users vulnerable to further attacks.
