Luxury fashion has now been added to the list. Global fashion brand Dior has informed U.S. customers of a data breach that occurred in May, exposing personal information during a cybersecurity incident. The compromised data includes contact numbers, home addresses, and, in some cases, government-issued IDs.

Dior data breach exposes sensitive customer information
Dior has started notifying U.S. customers of a data breach that exposed sensitive personal information after a cybersecurity incident earlier this year. In a notification letter, the French brand reveals that the breach took place on Jan. 26, 2025, but was not discovered until more than three months later, on May 7.
“The House of Dior recently discovered that an unauthorized external party accessed some of the data we hold for our Dior Fashion and Accessories customers. We immediately took steps to contain this incident,” the company stated to CyberGuy in a release.
The compromised data includes names, contact details, physical addresses, dates of birth, and, in some cases, passport or government-issued ID numbers. Social Security numbers were also exposed for a subset of affected individuals.
The company, part of the LVMH luxury group, clarified that no payment or financial data was stored in the affected systems.
“No payment information, including bank account or payment card information, was contained in the database accessed,” the company confirmed, adding that law enforcement has been alerted, and third-party cybersecurity experts were engaged to investigate.
Despite the breach occurring in January and being discovered in early May, customers were only informed in late July, prompting questions about the delay. This timeframe between detection and disclosure is raising concerns, particularly considering the sensitive nature of the compromised data.

Previous Dior and LVMH breaches suggest larger pattern
This incident mirrors a previously reported breach involving Dior customers in South Korea and China. Although no impact in the U.S. was mentioned at the time, the timeline aligns. Additionally, the sibling brand Louis Vuitton, also owned by LVMH, recently disclosed similar breaches affecting customers in the U.K., Turkey, and South Korea.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?
Dior has not confirmed the number of U.S. customers affected or the full extent of the breach. However, BleepingComputer reports that the same attack targeted Dior and Louis Vuitton. Investigators have tentatively linked the breach to the ShinyHunters extortion group, which reportedly gained access to the data through a compromised third-party vendor.
ShinyHunters has a history of targeting large organizations and selling stolen data on hacking forums. If the group is indeed responsible, further disclosures from other LVMH brands may follow. Louis Vuitton could soon notify U.S. customers if their data was similarly exposed.

2. Consider identity theft protection services
Given that the Dior data breach exposed personal information, it’s crucial to proactively protect yourself against identity theft. One effective way to do this is by using an identity theft protection service.
These services send real-time alerts about suspicious activities, such as new credit inquiries or attempts to open accounts in your name. In addition to monitoring, many identity theft protection companies offer dedicated recovery specialists who can help you address fraud issues.

3. Implement strong antivirus software
Since hackers have access to people’s email addresses and full names, they can easily send phishing links that install malware and steal your data. These messages are designed to deceive, and detecting them is nearly impossible if you’re not cautious. However, you have defenses in place.

4. Enable two-factor authentication
Even though passwords were not compromised in the data breach, it’s essential to enable two-factor authentication (2FA). This adds an extra layer of security to all your important accounts, including email, banking, and social media.
5. Be cautious of mailbox communications
Malicious actors may attempt to scam you through traditional mail as well. The data leak provides them with access to your address, allowing them to impersonate people or brands you know and use urgent themes to grab your attention. This includes fake delivery notices, account suspensions, and security alerts.
