What You Need to Know about the Cartier Data Breach

Swiss-owned luxury jeweler, Cartier, has had its website hacked and customer data compromised in the incident. Cartier, a subsidiary of Richemont, produces some of the world's finest watches, bracelets, and necklaces, which have been worn by Michelle Obama, Taylor Swift, and Angelina Jolie.

The Cartier data breach involved unauthorized access by an external party to Cartier's systems, exposing limited client information, including names, email addresses, countries of residence, and, in some cases, birth dates. However, the company claims no passwords, credit card details, or other financial information were affected in the breach.

Cartier promptly contained the breach, improved its cybersecurity measures, and notified relevant authorities. The company also worked with external cybersecurity experts to assist in the investigation and strengthen its defenses. Still, Cartier advised customers to remain vigilant for potential phishing attempts or suspicious communications.

This Cartier data breach is part of a broader trend of cyberattacks targeting high-profile fashion and luxury brands. Recent victims include Dior, Victoria's Secret, and The North Face, indicating cyberattacks targeting brands holding valuable customer data and not only credit card, or financial information.

When Was the Cartier Data Breach?

While it is still unclear when Cartier data was breached by cyber attackers, the company disclosed the leak on June 2, 2025. While the company did not state the number of customers impacted in the breach, it claimed that passwords and banking information were not involved in the breach.

How to Check if Your Data Was Breached

Cartier has notified customers affected by the data breach via the email registered with the company. Therefore, you may check your e-mail account or monitor it for notifications originating from Cartier. However, if you have not received any notification from the company but suspect that your data may have been leaked in the breach, you may use services like HaveIBeenPwned.com and AmIBreached.com to perform a data-leak lookup.

What to Do If Your Data Was Breached

Although Cartier reported no credit card, passwords, or financial information leak in the June 2025 data breach, it is important that you take proactive steps to safeguard yourself if you were affected by the breach.

One key step that you may take is monitoring your email and communications, or unsolicited messages or emails that may attempt to phish for additional personal information. You should verify the authenticity of the sender of any message or email before clicking on any links or downloading attachments. Cybercriminals may use compromised information to craft convincing phishing emails. Therefore, avoid providing personal information through email and report any suspicious messages to the appropriate authorities.

Additionally, keep abreast of updates from Cartier regarding the breach. With the company engaging external cybersecurity experts to investigate the incident, further notifications may yet be sent by the company to the affected clients.

Are There Any Lawsuits Because of the Cartier Data Breach?

No class action lawsuits have been officially filed against Cartier concerning the recent data breach as of early June 2025. However, some law firms are actively investigating the incident and are encouraging affected individuals to come forward. For instance, Potter Handy, LLP and Cole & Van Note have initiated inquiries into the breach. 

These law firms are collecting information from customers who received notification letters from Cartier regarding the unauthorized access to their personal data. These investigations aim to determine whether Cartier failed to implement adequate security measures to protect customer information, potentially violating data protection laws.

While no lawsuits have been filed yet, the ongoing investigations could lead to legal action if sufficient evidence is found indicating negligence or failure to comply with data protection regulations.

Can My Cartier Information Be Used for Identity Theft?

Although the Cartier data breach did not involve passwords, credit card numbers, or banking information leaks, the compromised data (names, email addresses, countries of residence, and, in some cases, birth dates) may still pose risks for identity theft.

For instance, via phishing attacks, attackers may use emails appearing to originate from legitimate sources to trick victims into disclosing further personal information that may be used for identity theft. Also, in social engineering attacks, malicious actors may use the knowledge of a victim's country of residence and other personal details to manipulate them or organizations into divulging sensitive information.

What Can You Do to Protect Yourself Online?

In order to protect yourself from online data breaches, consider taking the following steps:

• Change Your Email Passwords: Even though passwords were not part of the Cartier data breach, attackers may attempt to access accounts using leaked emails. Updating your email password, especially if reused elsewhere, is still a useful step.
• Enable Two-Factor Authentication (2FA): Activating 2FA on your online accounts ensures that even if someone has your email address, they cannot access your account without the second verification step.
• Be Cautious of Phishing Emails: Avoid clicking on links or downloading attachments unless you are certain of the source. Check sender addresses and spelling carefully.
• Monitor Online Accounts: Watch for unauthorized logins or activity in your email, social media, and e-commerce accounts. Unusual login notifications or password reset emails you did not initiate may be signs of compromise.
• Consider a Credit Freeze or Alert: If your personal information was exposed in the breach, consider placing a credit freeze or fraud alert to prevent identity theft.
• Unsubscribe from Unfamiliar Emails: Leaked email addresses may be added to spam or scam mailing lists. Unsubscribe cautiously and mark suspicious messages as spam to reduce exposure.
