# CUC Loisirs & Vacances (Clermont Université Club)

Data breach — Critical

CUC Loisirs & Vacances, a branch of the Clermont Université Club (Clermont-Ferrand) that runs leisure centers, camps and holiday programs for children, is the subject of a hacking claim published on September 18, 2026 on a cybercriminal forum. The attacker claims to have compromised the cuc-loisirs.fr website and obtained a database of about 8,915 registration records, mostly from older files (2015-2016). The sample released shows identity and contact data for children and their legal guardians, social security numbers, CAF benefit data, and medical information (allergies, asthma, treatments).

This data, particularly the medical and social security information concerning minors, could allow a malicious third party to target the families involved or attempt identity theft.

## Exposed data

- Full name
- Phone number
- Postal address
- Date of birth
- Email address
- Customer ID
- Employment data
- Social security number
- Health data

## What you can do

- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- These documents enable identity theft, and cannot be reissued at will. Keep the notification letter: it proves where the leak came from if an account is opened in your name.
- Health data is “special category” data under the GDPR: a leak opens a right to compensation, and the organisation must notify the DPA within 72 hours.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
