Neiman Marcus said Thursday it was notifying 4.6 million customers that some of their personal information, including credit card numbers and user names and passwords, may have been obtained in a May 2020 data breach.
The Dallas-based luxury retailer said in a news release that it recently learned an "unauthorized party" had gained access to certain information of customers' online accounts. The company notified authorities and is working with a cybersecurity firm to investigate the nature and scope the breach.
The data may have included names and contact information, credit card numbers and expiration dates (but not the CVV numbers on the back of the cards), Neiman Marcus virtual gift card numbers (without PINs), usernames, passwords, and security questions and answers associated with Neiman Marcus online accounts.
More than 85% of the approximately 3.1 million payment and virtual gift cards affected were "expired or invalid," according to the company. No active Neiman Marcus-branded credit cards were impacted.
