The incident was publicly disclosed in early April, when the company announced that it shut down “IT systems across multiple locations and business units” to contain the issue.

The company also said that the cyberattack was detected in its early stages, and that it immediately set up an incident response team to investigate and address the breach.

On Tuesday, the wind turbine maker published an updated incident notification, saying that it was still working on restoring systems to “enable business continuity and resume normal operations as soon as reasonably practicable.”
