Hong Kong’s privacy watchdog has launched a formal investigation into a significant data breach involving luxury fashion brand Louis Vuitton, after the personal information of approximately 419,000 customers in the city was compromised.

The Office of the Privacy Commissioner for Personal Data (PCPD) confirmed on Monday that it is examining the breach, which exposed sensitive customer data including names, passport details, residential addresses, email addresses, phone numbers, shopping history, and product preferences. Louis Vuitton has clarified that no payment or financial information was affected.

According to a statement from the PCPD, Louis Vuitton’s French headquarters first detected suspicious activity on its IT systems on June 13. It was not until July 2 that the company discovered Hong Kong customers were among those impacted. The breach was formally reported to Hong Kong authorities on July 17, raising concerns about a possible delay in notifying regulators.

The watchdog’s investigation will assess whether Louis Vuitton Hong Kong met its obligations under the Personal Data (Privacy) Ordinance, including whether the delay in reporting the incident was justified. Authorities will also evaluate whether adequate data protection measures were in place to prevent unauthorized access.

Louis Vuitton, owned by French luxury conglomerate LVMH, said in an emailed statement that it had identified unauthorized access to client data and has since taken action to secure its systems. The company is cooperating with regulators and reaching out to affected customers. It has also emphasized that there is currently no evidence that the exposed information has been misused.

This breach follows a string of similar incidents involving Louis Vuitton in other countries, including South Korea, the United Kingdom, Australia, and New Zealand. In each case, customer data has been compromised, prompting global scrutiny of the brand’s cybersecurity infrastructure.

In Hong Kong, privacy officials are particularly concerned with how the breach has been handled and whether consumer trust has been eroded. The PCPD has urged individuals affected by the leak to remain vigilant, especially against potential phishing attempts or identity fraud. Consumers are advised to monitor their email accounts and travel documents closely and to avoid sharing personal information in response to unsolicited communications.

Cybersecurity analysts note that the recurring nature of these breaches across different countries indicates a broader challenge for global luxury brands in protecting customer data. The repeated incidents have already impacted LVMH’s market performance, with shares seeing a slight decline as investor confidence wavers.

While Louis Vuitton continues to investigate the root cause and extent of the breach, the Hong Kong investigation is expected to determine whether the brand complied with its legal responsibilities and if any enforcement action is necessary. The findings could influence how data breach disclosures are handled in future incidents, particularly for global companies operating in multiple jurisdictions.

For now, Hong Kong authorities are working closely with their counterparts abroad as the full scale of the breach becomes clearer.
