The impacted customers have reached over 4.6 million people, of which they have sent notifications regarding the attack that may have begun by May last year.
From the clients’ online accounts, the exposed details to the data breach include their names, addresses, usernames, passwords, payment card numbers with expiration dates, Neiman Marcus virtual gift card numbers, and the security questions of clients who have online accounts.
Over 85% of the data breach impacted Neiman Marcus department store has expired or invalid payment and virtual gift cards.
As stated in the luxury department store’s news release, roughly 3.1 million out of the 4.6 million have affected the customers’ payment and virtual gift cards. Furthermore, over 85% of those have already been expired or invalid for use.
Neiman Marcus Group (NMG) also added that they have only been aware of the recent data breach attack despite occurring a year ago. From the alerts sent, they prompted their customers to change their account passwords immediately. The luxury department store has already notified law enforcement and security analysts to help resolve the situation.
The luxury department store has set up a dedicated web page to instruct the affected clients about their awareness regarding any suspicious activities in their accounts. Affected clients can also request a free copy of their credit report.
