Cartier, the French luxury jewelry and watchmaker, was caught up in a broad attack campaign targeting Salesforce, the customer relationship management platform used by businesses worldwide. A threat group calling itself "Scattered LAPSUS$ Hunters" claimed responsibility and listed Cartier among roughly 39 organizations on its dark web leak site in October 2025. The group released a sample of stolen data on October 3, 2025, and announced plans to publish the full dataset on October 10, 2025. The breach affected an estimated 45.4 million customer records. The exposed data includes customer names, birthdates, country of residence, email addresses, and internal account identifiers. While financial details and physical addresses do not appear in the confirmed sample, the combination of real names, birthdates, and verified email addresses belonging to Cartier customers is particularly sensitive. Cartier's clientele are buyers of high-value jewelry and watches, making this list an attractive target for phishing, impersonation scams, and fraud schemes designed to exploit high-net-worth individuals. Cartier has not made detailed public statements about the scope of its exposure. No regulatory actions or formal breach notifications have been publicly confirmed as of the time of this report. Affected individuals should be alert to unsolicited emails purporting to be from Cartier or related luxury brands, treat any requests for account verification or payment information with caution, and be aware that their status as Cartier customers may itself be used as leverage in social engineering attempts.

Luxury jewelry and watch brands collect customer identity, contact details, addresses, purchase histories, service records, and payment-adjacent data across retail and after-sales operations.

Cartier has continued operating within the Richemont group through a period of variable luxury goods demand, particularly in the key Chinese market. Richemont has reported solid performance in its jewelry maisons division — which includes Cartier — relative to broader luxury market softness. The brand has invested in digital retail and clienteling tools as part of its customer engagement strategy.
