Global Louis Vuitton Data Breach Impacts Multiple Countries

Louis Vuitton, the renowned French luxury retailer, has notified customers of a data breach that has affected multiple countries, including the UK, South Korea, and Turkey. The security incident, discovered on July 2nd, 2025, exposed personal information such as names and contact details. However, the company confirmed that passwords, payment card data, and other financial information were not compromised. The breach may have impacted customers in other countries as well, as notifications are still ongoing.

Details of the Data Breach

Last week, Louis Vuitton disclosed that data of some UK customers had been stolen. Threat actors gained access to the company’s UK operation systems, obtaining information such as names, contact details, and purchase history. The brand also reported a similar cyberattack on its Korean operation.

“While we have no evidence that your data has been misused to date, phishing attempts, fraud attempts, or unauthorised use of your information may occur,” reads the email sent to impacted customers, as reported by The Guardian¹.

Company Response and Notifications

Louis Vuitton, owned by the French luxury group LVMH, has notified relevant authorities, including the Information Commissioner’s Office. This marks the third breach of LVMH’s systems in three months, underscoring the escalating cyber threats faced by luxury brands.

Attackers accessed Louis Vuitton’s systems nearly a month before detection. According to Security Week², around 143,000 residents in Turkey were affected. The security breach may be linked to a third-party service provider account.

Potential Ransomware Attack

At this time, Louis Vuitton has not provided technical details about the attack. However, public information suggests it was a ransomware attack, although no ransomware group has claimed responsibility for the incident.

Industry-Wide Cyber Threats

Recently, another luxury brand, Cartier³, disclosed a data breach following a cyberattack that compromised its systems, exposing customers’ personal information. This incident is part of a broader wave of cyberattacks targeting luxury fashion brands, highlighting the urgent need for enhanced cybersecurity measures in the industry.

Conclusion

The Louis Vuitton data breach serves as a stark reminder of the increasing cyber threats facing luxury brands. As the digital landscape evolves, companies must prioritize robust cybersecurity measures to protect customer data and maintain trust. The incident underscores the importance of vigilance and proactive security strategies in safeguarding against future attacks.
