The Neiman Marcus Group (Dallas) announced over the weekend that it’s investigating a security breach involving credit card information stolen from its customers during the last month.
The company said some customers’ credit card details may have been stolen, but did not say how many records were potentially compromised.
“We have begun to contain the intrusion and have taken significant steps to further enhance information security,” the company said in a statement, adding it was notifying customers whose cards were used fraudulently after making a Neiman Marcus purchase.
Neiman Marcus’ announcement came at the same time that Target Corp. (Minneapolis) was revising the number of customers affected by its security breach in December. The retail now says it was a range of between 70 million and 110 million people – nearly three times the original estimate.
Target also disclosed that the hackers had stolen a broader trove of data than originally reported. The company now says that other kinds of information were taken, including mailing and email addresses and phone numbers or names, the kinds of data more often collected during online or telephone transactions.
