Card data of Supervalu and Albertsons shoppers may be at risk in another hack, the two supermarket companies said Monday. The companies said that in late August or early September, malicious software was installed on networks that process credit and debit card transactions at some of their stores. Albertsons said the malware may have captured data including account numbers, card expiration dates and the names of cardholders at stores in more than a dozen states. Supervalu said the malware was installed on a network that processes card transactions at several chains, but it believes data was only taken from certain checkout lanes at four Cub Foods stores in Minnesota. The breach could affect Albertsons stores in California, Idaho, Montana, Nevada, North Dakota, Oregon, Utah, Washington and Wyoming; Acme Markets stores in Delaware, Maryland, New Jersey and Pennsylvania; Jewel-Osco stores in Illinois, Indiana and Iowa; and Shaw's and Star Markets stores in Maine, Massachusetts, New Hampshire, Rhode Island and Vermont. The Boise, Idaho-based company has a total of 1,081 stores. The companies also disclosed a data breach in August. They said the two incidents are separate.
