Tiffany & Co. Confirms Data Breach in South Korea, Raising Concerns About LVMH's Cybersecurity

Tiffany & Co. has confirmed a data breach affecting some of its customers in South Korea. The incident is raising concerns about cybersecurity at LVMH, the luxury goods giant that owns Tiffany, especially since Dior—another LVMH brand—also experienced a similar breach recently.

On May 26, Tiffany Korea emailed select customers to inform them about the breach. According to the company, the issue involved unauthorized access to a third-party platform used to manage customer information. The breach actually happened on April 8 but wasn’t confirmed until May 9, when the company verified that personal data had been compromised.

The information exposed includes customers’ names, addresses, phone numbers, email addresses, internal customer ID numbers, and purchase history. This kind of data is considered sensitive, especially when it involves luxury brand clients.

So far, Tiffany says there have been no confirmed cases of the leaked data being misused. Only the affected customers were notified, and as of now, there’s been no public announcement posted on Tiffany Korea’s website.

Tiffany & Co. was acquired by LVMH in January 2021 in a deal worth around $12.4 billion (17 trillion won). Tiffany Korea reported strong performance last year, earning about $276 million in sales and over $15 million in operating profit.

The back-to-back data breaches at Dior and Tiffany are raising larger questions about how well LVMH is protecting its customer data across its brands.
