Renault notified an unspecified number of customers that their personal data was compromised due to a cyber-attack on a third-party supplier. The breach exposed customers' first and last names, gender, phone numbers, email and postal addresses, as well as vehicle identification and registration numbers. While no financial data or passwords were stolen, the exposed information increases the risk of targeted phishing scams. The incident was isolated to the supplier’s systems, with Renault confirming its own infrastructure remained uncompromised. The third-party provider contained and removed the threat, and Renault is collaborating with them to ensure appropriate measures are taken. Authorities were notified, and customers were advised to remain vigilant against unsolicited requests for personal information. The breach follows a trend of supply chain attacks in the transport sector, highlighting vulnerabilities in vendor security.
