The dairy giant said it immediately took steps to contain the threat, and notified the appropriate authorities.
It added that the results of its investigations have established a malicious third party was trying to break into its servers.
Lactalis’ IT teams were fully mobilized and supported by cybersecurity experts. The company said its initial investigation has not revealed any data breaches.
Groupe Lactalis said its teams are working to protect the interests of its customers, partners and employees, and has restricted, as a preventive measure, access to the public internet network.
The company added it was operating normally following the attempted attack.
