On or around **May 12, 2025**, Tiffany & Co., a luxury jewelry retailer, suffered a **cybersecurity breach** after a threat actor ('Market Exchange') infiltrated its systems. The attack exposed **personally identifiable information (PII)** of **at least 2,590 confirmed individuals**, including names, addresses, emails, phone numbers, sales transactions, client reference numbers, and **Tiffany gift card details (with PINs)**. The actor later claimed possession of a broader database containing records of **~720,000 high-spending U.S. customers**, predominantly women. The breach was disclosed to authorities and affected individuals in **September 2025**, with notifications sent via mail. While no financial fraud was immediately reported, the exposure of **gift card PINs** and **detailed customer profiles** poses risks of **identity theft, phishing, and unauthorized transactions**. Tiffany & Co. engaged cybersecurity experts and law enforcement but did not confirm whether ransomware or additional system compromises (e.g., operational disruption) occurred. The incident highlights vulnerabilities in **customer data protection** within high-end retail.
