Louis Vuitton Data Leaked in International Cyberattack

Louis Vuitton has confirmed that approximately 419,000 customers had their personal data compromised in an international cyberattack that occurred on July 2, 2025, affecting customers across multiple countries including South Korea, Turkey, the United Kingdom, Italy, and Sweden.

The breach, which is believed to be linked to the ShinyHunters extortion group, exposed customer information such as names, email addresses, phone numbers, contact details, and purchase history through unauthorized access to the luxury retailer's systems. According to statements from Louis Vuitton, the attack originated from a compromised third-party service provider account, with the initial breach occurring in early June but not discovered until July 2. Importantly, the company has emphasized that no financial data, including credit card numbers, bank account details, or passwords, were stored in the compromised database.

This cyberattack represents the third security incident to hit LVMH brands in recent months, following similar breaches at Christian Dior Couture in May 2025 and an earlier Louis Vuitton Korea incident. The pattern of attacks on luxury retailers has raised concerns among cybersecurity experts, with other high-end brands including Cartier, Victoria's Secret, and Adidas also experiencing data breaches during the same period. Louis Vuitton has notified relevant government authorities including data protection boards in affected countries and has engaged leading cybersecurity experts to investigate the incident and strengthen system defenses. The company has sent notifications to affected customers warning them to remain vigilant for potential phishing attempts, fraudulent activity, or unauthorized use of their information, even though there is currently no evidence that the stolen data has been misused.

How Uristocrats Can Protect Their Personal Information: In light of this and other recent data breaches affecting luxury brands, there are several steps you can take to safeguard your personal information.

• Enable two-factor authentication on all accounts where available, use unique and strong passwords for each online account (consider using a reputable password manager), and regularly monitor your financial statements and credit reports for suspicious activity. B
• e extremely cautious of unexpected emails or messages claiming to be from luxury brands, especially those requesting personal information or login credentials—legitimate companies will never ask for passwords via email.
• When shopping online, only use official brand websites or verified retailers, avoid saving payment information on websites when possible, and consider using virtual credit card numbers or digital payment services that provide additional security layers.
• Finally, regularly review and limit the personal information you share with retailers, and take advantage of privacy settings that allow you to control how your data is used and shared.
