French fashion house Christian Dior informed some of its customers via text message Monday night of a data breach involving unauthorized access to a portion of its customer information.

According to the message, Dior discovered on May 7 that external parties without authorization had accessed certain customer data held by the brand. The leaked information includes customers' names, gender, phone numbers, email addresses, mailing addresses, purchase amounts, shopping preferences, and other user data collected by the brand.

The message emphasized that no financial information - such as bank account details, IBANs, or credit card data - was contained in the compromised database.

The message was only sent to those whose personal information has been breached, according to Dior customer service.

The company urged Chinese customers to remain highly vigilant. It advised against opening or clicking on suspicious messages, calls, or emails from unknown sources, and warned users not to disclose verification codes, passwords, or other sensitive information.

Speaking to the Global Times on Tuesday, a Dior customer service representative confirmed the incident, stating, "We recently identified a security breach that resulted in unauthorized access to certain data we hold, including customer information. Upon discovering the issue, we immediately took steps to contain it."

The representative added that the incident is still under investigation and that no further details are available at this stage. "If there are any developments in the investigation, customers with inquiries will be updated directly via phone," he said.
