Leak at France Ventilation

On 12 December 2025, France Ventilation — a French specialist in ventilation and air-treatment systems — disclosed that it had fallen victim to a cyberattack that compromised its customers' banking information.

According to the public alert from cybersecurity researcher Clément Domingo (SaxX), the exposed data included full payment card details, putting affected customers at direct risk of banking fraud. The company acknowledged that customers' banking credentials had been leaked.

Exposed data categories included:

• Payment card number
• Card expiration date
• CVV (card verification value)

The exact attack vector and the number of customers affected were not publicly confirmed. Because the leak contained complete card data (number, expiry and CVV together), affected customers were urged to monitor their accounts and consider having their cards reissued. The status of the company's remediation and any regulatory notification to the CNIL was not disclosed at the time of reporting.
