Luxury fashion brand Cartier has warned its customers about a recent data breach that unfortunately exposed some of their personal information. According to official notification letters sent out on Monday, June 2nd, an unauthorized party gained temporary access to Cartier’s internal systems. This intruder successfully obtained limited client information during the security incident, prompting immediate company action to fully address the compromise. The compromised data reportedly includes customer names, their registered email addresses, and also the countries where these affected customers currently reside. Cartier has emphasized that more sensitive data like passwords, various credit card numbers, or any banking details were not included in this breach.
Cartier stated it quickly contained the discovered security issue and has since further enhanced the overall protection of its valuable systems and data.
The company has officially informed all relevant authorities about this incident and is currently working very closely with external cybersecurity specialists. These engaged specialists are now assisting Cartier to thoroughly investigate the breach and to significantly strengthen its future security posture. While sensitive financial data was not taken by the attackers, Cartier specifically warns that the stolen personal information could potentially be used. This information might be exploited in future targeted attacks against its customers, necessitating increased awareness from all affected individuals by this breach.
This concerning data breach at the luxury brand Cartier notably follows several similar security incidents that have affected other major fashion brands. For example, in May 2025, the renowned fashion house Dior disclosed a significant data breach after various threat actors successfully breached its systems. Those attackers managed to steal Dior customer contact details, their extensive purchase histories, and also their stated product preferences from the company’s database. Also during last month, sportswear giant Adidas similarly warned its customers about a data breach which directly resulted from a compromise.
This compromise occurred at one of its crucial third-party service providers that handled customer data, impacting many individuals globally.
Although Cartier did not disclose specific details about the exact method or the origin of this particular data breach affecting their systems. This serious incident unfortunately comes to light only a few weeks after several prominent UK retailers were targeted by DragonForce. That separate ransomware campaign against Co-op, Harrods, and Marks & Spencer resulted in significant data theft and potentially large financial losses. Cartier has not yet stated how many of its customers were impacted by their breach or exactly when this incident was detected. The company is now focusing its efforts on the ongoing investigation and also on enhancing its overall cybersecurity measures. This is to prevent future occurrences of such damaging cyberattacks.
