Cybercriminals hacked into Groupe Beneteau’s server network sometime last week, the company said, which forced a full network shutdown, as well as delays at some manufacturing facilities in France.

Groupe Beneteau released a statement that read, in part:

“Accompanied by experts and the relevant authorities, the group’s teams are fully mobilized to address the consequences of this attack. Firstly, the deployment of a backup application and systems will enable activities to start up again securely, but in degraded mode. Alongside this, investigations will continue moving forward with a view to fully restoring all of the group’s systems.”

Groupe Beneteau said that its full-year revenue report Feb. 25 will include more information about the breach.
