Cartier, the renowned luxury jewellery and watchmaker owned by Swiss-based conglomerate Richemont, has notified customers of a recent data breach involving limited personal information due to a system vulnerability. The company assured that the breach was quickly contained and confirmed that no financial data or sensitive login credentials were compromised.
In notification letters—some of which have surfaced online—Cartier stated that an unauthorized party briefly accessed its systems and obtained certain customer information, including names, email addresses, and countries of residence. However, the company emphasized that payment details, passwords, and banking data were not affected.
Despite the limited scope of exposed data, Cartier has advised customers to remain cautious of any unsolicited or suspicious messages that may follow. “Due to the nature of the data involved, we recommend staying alert for any unusual communication,” the brand noted.
Cartier has reported the incident to law enforcement and is collaborating with an external cybersecurity firm to investigate the breach and strengthen its security measures. “We have contained the issue and implemented additional safeguards to protect our systems and customer data,” the company said.
This incident places Cartier among a growing list of luxury and retail brands targeted by cyberattacks in recent weeks. Dior recently disclosed a breach involving customer contact details and shopping habits, while Adidas and Victoria’s Secret also reported separate security incidents involving their digital infrastructure.
