Supervalu, the third-largest food retailer in the United States, is investigating a network intrusion that may have resulted in the theft of customer data from 180 Supervalu grocery stores, including franchised stores, as well as standalone liquor stores across seven states. The point-of-sale breach may have also affected an unspecified number of Albertsons, ACME Markets, Jewel-Osco, Shaw's and Star Markets stores in 21 states.
The organization reported that the unauthorized access to its systems took place between June 22 and July 17 at the latest. The breach possibly compromised payment card numbers, cardholders' names, card expiration dates and other numerical information not defined by the company.
Supervalu president and CEO Sam Duncan said that the intrusion was identified and quickly contained. There was no evidence of misuse of any customer data, he said.
