Cartier data breach 2025: Customer emails and info leaked in major cyberattack

New Delhi: Another week, another luxury brand hacked. This time it’s Paris-based Cartier, the global jewellery giant, now dealing with the fallout from a cyberattack that exposed customer information. The incident puts Cartier in the same breach-hit basket as Dior, Adidas and Victoria’s Secret, all of whom have suffered data incidents over the past month.

Cartier confirmed the breach in an email to customers, warning that hackers briefly gained access to its systems and made off with basic client data. While the company insists that sensitive information like credit card or banking details was not stolen, the stolen customer names, email addresses and countries could still open doors to targeted phishing attacks.

What was stolen?

According to the breach notification email, Cartier said the hackers only accessed “limited client information.” That includes:

• Names
• Email addresses
• Country of residence

Cartier clarified that no passwords, payment information or banking details were affected. The company said, “We contained the issue and have further enhanced the protection of our systems and data.”

Customers were advised to stay alert for unsolicited or suspicious emails. That’s standard advice, sure, but these days, even clicking on what looks like a brand newsletter could land you in serious trouble.

Brands under fire

Fashion brands are now a growing target for cybercriminals. Over the past few weeks:

This recent wave of attacks also follows incidents involving UK retailers like Co-op, Marks & Spencer, and Harrods. DragonForce, a ransomware group, had claimed responsibility for some of those breaches. The M&S breach alone could cost the retailer around $400 million (₹3,480 crore).

Investigations underway

Cartier said it has informed law enforcement and is working with an external cybersecurity company to investigate the breach. It hasn’t disclosed when the breach occurred or how many customers were affected.

The message from Cartier was pretty clear. “We recommend that you remain alert for any unsolicited communications or any other suspicious correspondence.”

Why fashion brands?

It’s not just about selling expensive handbags. These companies sit on rich databases full of customer identities, contact details and shopping behaviour. That makes them juicy targets. And since luxury customers tend to be high-net-worth individuals, their data is even more valuable.

If you’re a customer of any of these fashion labels, now might be a good time to update your passwords, double-check your inboxes, and maybe skip clicking that “Cartier Gift Offer” mail.
