Cartier

Cartier is recognized as a luxury fashion brand. The company's headquarters is situated in France. On November 1, 2025, Cartier detected a data breach after unauthorized individuals gained temporary access to its systems. The breach led to the exfiltration of limited client information, specifically names, email addresses, and countries of residence. Importantly, the compromised data did not include passwords, payment card numbers, or banking details. In response, Cartier contained the incident, enhanced its security controls, notified law enforcement, and engaged an external cybersecurity firm for remediation. The firm advised affected individuals to remain vigilant for unsolicited or suspicious communications that could exploit the exposed data.

A separate security incident occurred on June 1, 2025, when hackers again obtained temporary access to Cartier's systems. This earlier breach resulted in the theft of customer names, email addresses, and countries of residence, while passwords, payment details, and banking information remained secure. Following the June breach, Cartier informed law enforcement authorities and collaborated with cybersecurity experts to address the vulnerability. The company also urged customers to stay alert for suspicious communications after the June incident. The June 2025 breach is noted as part of a broader trend of cyberattacks targeting fashion brands, with peers such as Dior, Adidas, and Victoria's Secret similarly engaging external security firms for investigations.
