Dior’s coveted client list of China’s wealthiest and most powerful consumers has been compromised in a major data breach, forcing the French luxury giant to issue an apology as it scrambles to contain potential fallout and limit any damage to its reputation.

The luxury brand under French conglomerate LVMH experienced a customer data breach in China on May 7. According to a text message sent to customers yesterday, the company disclosed that an unauthorized external party had gained access to its database, obtaining sensitive personal information such as customers’ names, gender, phone numbers, email addresses, mailing addresses, purchase amounts, and shopping preferences.

Dior emphasized that the compromised data did not include bank account details, IBANs (International Bank Account Numbers), or credit card information. Nonetheless, the brand urged customers to exercise heightened caution, advising them to beware of phishing messages, unsolicited calls or emails, and to avoid clicking on suspicious links or disclosing personal information.
