On 31 March 2026, La Mine Bleue — a slate-mine tourist attraction in Anjou, western France — notified its customers that some of their personal data had been exposed. The leak did not originate at La Mine Bleue itself but at Vivaticket, the third-party online ticketing platform it uses to sell visits.
Vivaticket was hit by a ransomware attack detected on 2 March 2026, claimed by the RansomHouse group. The platform handles ticketing for roughly 3,500 cultural organisations worldwide — including the Louvre, the Bibliothèque nationale de France and the Centre des monuments nationaux — and the intrusion allowed attackers to exfiltrate customer records held on its systems, La Mine Bleue's among them.
The data exposed for affected La Mine Bleue customers included:
- Last name and first name
- Postal code and country
- Email address
- Purchase / reservation history
La Mine Bleue stated that no banking or payment-card data was involved, and that passwords were not exposed. Customers were urged to stay alert to phishing messages impersonating La Mine Bleue or its partners. Vivaticket reported the incident to the authorities and is working with France's national cybersecurity agency (ANSSI) on the forensic investigation. The exact number of La Mine Bleue records affected has not been disclosed.
