The world’s largest manufacturer of wind turbines was forced to shut down IT systems across several locations over the weekend after a cybersecurity incident.

In a brief notice on Saturday, Vestas Wind Systems claimed the attack struck the day before, with IT services in multiple business units affected.
At the time, the Danish firm said that customers, employees and other stakeholders could be affected by the incident, and that it was working with internal and external partners to contain and recover.

An update on Monday morning warned that data had been compromised.

“However, there is no indication that the incident has impacted third party operations, including customer and supply chain operations,” it added.
Although not confirmed by Vestas, a ransomware attack would appear to be the front-runner in terms of likely cause. The turbine giant reported revenues of nearly €15bn in 2020, making it a potentially lucrative target.

Vestas claimed that its investigation is ongoing as the firm tries to “re-establish the integrity of its systems.”

Wind turbine maker Vestas confirms recent security incident was ransomware
November 28, 2021

Wind turbine maker Vestas says "almost all" of its IT systems are finally up and running 10 days after a security attack by criminals, confirming that it had indeed fallen victim to ransomware.

Alarm bells rang the weekend before last when the Danish organisation said it had identified a "cyber security incident" and closed off parts of its tech estate to "contain the issue."
Today the business - one of the largest worldwide to design, build, install and maintain wind turbines – said it has undertaken "extensive investigations, forensics, restoration activities and hardening of our IT systems and IT infrastructure."

Henrik Andersen, president and chief exec of the firm, said in a statement:

"We have been through some tough days since we discovered the cyber incident, and executive management and the board of directors are thus very pleased that the incident didn't impact wind turbine operations and almost all of our IT systems are running again."
The security incident bore all the hallmarks of a ransomware attack, but Vestas last week refused to comment. Today it confirmed what The Register had previously suspected.
