Albertson's and Supervalu shoppers beware. The two companies discovered malware installed on their payment processing system that could have put your credit card information at risk. It's the latest in an ongoing string of cyberthefts that's keeping shoppers on edge.
This isn't the first time both of these stores have been hit by hackers this year. In June and July, cybercriminals accessed one of the store's payment processors and stole customer credit card information.
The companies also disclosed a data breach in August. They said the two incidents are separate. Supervalu said that incident may have affected as many as 200 grocery and liquor stores. It said hackers accessed a network that processes Supervalu transactions, with account numbers, expiration dates, card holder names and other information.
This time around, the companies discovered malware installed on payment processing networks that could have stolen account numbers, card expiration dates and the names of cardholders. Hacks at both grocery chains seem to coincide because Supervalu continues to operate information technology services for Albertsons after selling the chain in 2013.
Most Supervalu customers can breathe easy. The company began taking steps to lock down its payment processing machines after that hack, so only a few of its stores were still affected this time around. The company has said that only four Minnesota Cub Foods stores were vulnerable to the attack because they're the only locations in the Supervalu family that haven't undergone security improvements.
Albertsons hasn't released which of its stores were hit yet, but it could be quite a few.
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.
If you think you think you're data is at risk, you need to cancel the credit cards you've used at the stores immediately and request new cards from your financial institution. You should also check your statements regularly to keep an eye out for fraudulent charges.
