Deep Dive

Luxury fashion house Louis Vuitton is facing a cross-border cybersecurity incident after confirming a data breach that has affected customers in at least three countries and possibly more.

Notifications were issued to individuals in the United Kingdom, South Korea, and Turkey following a July 2 breach involving the theft of personal data such as names and contact details. According to Louis Vuitton, no passwords, financial information, or payment card data were compromised.

The company has not disclosed the full scale of the breach, but the statements issued across jurisdictions suggest the incidents are linked by the timing of the intrusion and the nature of the compromised data. In each country, the breach appears to stem from the same root cause: unauthorized access detected earlier this month but believed to have originated nearly a month prior.

In Turkey, Louis Vuitton reported that nearly 143,000 individuals were affected, citing a compromised account associated with a third-party service provider as the likely entry point. That detail raises fresh questions about the luxury retailer’s vendor risk management and the security standards applied to its digital supply chain.

South Korea and the UK have also issued notices, though without specifying the number of impacted customers. Meanwhile, other regions may be affected as well, but Louis Vuitton’s parent company, LVMH, has not yet released further information despite media inquiries.

So far, no known ransomware group has claimed responsibility, and there is no official confirmation that ransomware was involved. The absence of attribution adds to the uncertainty surrounding the breach, especially as similar incidents continue to plague high-end brands.

Last month, Cartier also announced a breach of its own, exposing customer data. North Face and other fashion brands were also recently hit, signaling a broader trend of cyberattacks targeting global retail giants.
