Report: Neiman Marcus computers hacked

OAK BROOK – Hackers breached the computer networks of luxury department store chain Neiman Marcus, including its Oak Brook location, as far back as July, and the attack was not fully contained until Sunday, according to media reports.

Neiman Marcus said on Friday that hackers may have stolen customers' credit and debit card information, the second cyber attack on a retailer in recent weeks, according to reports.

The store had said it first learned in mid-December of suspicious activity that involved credit cards used at its stores, read reports.

Neiman Marcus did not say how many credit cards were affected but said that customer social security numbers and birth dates were not compromised, according to reports.
