Breach Database / Neiman Marcus

Yes — Neiman Marcus was breached.

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.

What data was exposed

What to do right now

  1. Watch your card and bank statements. Set up transaction alerts, and consider a card freeze or replacement if the exposure included full card numbers.
  2. Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
  3. Watch for targeted phishing mail. A leaked home address makes postal and doorstep scams more convincing.
  4. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  5. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  6. Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
