Neiman Marcus Data Breach

What happened

In May 2024, the American luxury retailer Neiman Marcus suffered a data breach which was later posted to a popular hacking forum. The data included 31M unique email addresses, names, phone numbers, dates of birth, physical addresses and partial credit card data (note: this is insufficient to make purchases). The breach was traced back to a series of attacks against the Snowflake cloud service which impacted 165 organisations worldwide.

Exposed data

Recommended actions

• Watch for targeted phishing emails referencing Neiman Marcus — attackers weaponise breach data quickly.
• Monitor your bank and card statements closely and consider requesting a card replacement.
• Stay alert for smishing (SMS phishing) and SIM-swap attempts using your phone number.
• Exposed identity data raises identity-theft risk — consider credit monitoring or a credit freeze.
• Check whether your email address appears in this breach on haveibeenpwned.com.
