Luxury jewelry brand Cartier has disclosed a data breach that exposed customer information, warning clients via email that unauthorized actors gained temporary access to its systems.
The company emphasized that no passwords, credit card numbers, or banking details were compromised.
The breach was identified by Cartier’s internal security team, who discovered that an intruder had briefly accessed the firm’s client database. According to the notification sent to customers and shared publicly on X, the stolen data includes names, email addresses, and country of residence. Cartier stated that it has contained the breach, notified relevant authorities, and engaged external cybersecurity experts to bolster its defenses.

Cartier, a French luxury goods brand owned by Richemont Group, is one of the world’s most renowned names in high-end jewelry and watches, with a global footprint that spans over 200 stores across dozens of countries. Its clientele includes high-net-worth individuals, celebrities, and collectors, making it an attractive target for cybercriminals seeking either direct data theft or access to privileged customer networks.
While Cartier reassured customers that financial information was not involved, the incident raises concerns about targeted phishing attacks and scams that could exploit the exposed contact details. In the notification, the company urged recipients to stay vigilant against unsolicited messages and suspicious communications, noting that the nature of the compromised data may make users susceptible to social engineering attempts.
The exact date of the breach was not specified in the customer communication, but the company stated that it had already informed law enforcement and regulators and was actively working with cybersecurity specialists to investigate the incident. No information has been provided on how many customers were affected or whether the breach involved exploitation of third-party service providers, a factor that has been common in other recent breaches.
Cartier’s disclosure comes just days after German sportswear giant Adidas confirmed a customer data breach linked to vulnerabilities in its third-party customer service platforms. In Adidas’ case, the exposed data similarly included contact details but no payment or password information. Additionally, Victoria’s Secret recently faced a significant cyberattack that forced the company to take its website and some in-store systems offline as it investigated what is suspected to be a ransomware attack.
Although Cartier has not reported any fraudulent activity stemming from this breach, personal details like name and email can be valuable to attackers for crafting convincing phishing campaigns. Hence, customers are advised to be cautious of unexpected emails or messages asking for sensitive information and avoid clicking on suspicious links or downloading unexpected attachments.
