The grocery chain Supervalu said Friday that it may have suffered a data breach at stores in as many as five states. Hackers accessed a network that processes store transactions. Account numbers, expiration dates, cardholders' names and other information may have been stolen, the company said. Grocery stores — as well as some stand-alone liquor shops — in Minnesota, Virginia, Illinois, Maryland and Missouri may have been affected between June 22 and July 17. The cards from which data may have been stolen were used at 180 Supervalu stores and liquor stores run under the Cub Foods, Farm Fresh, Hornbacher's, Shop 'n Save and Shoppers Food & Pharmacy names. Supervalu said that it currently believes the data breach did not impact its owned or licensed Save-A-Lot stores or any of the independent grocery stores supplied by the company. Once it learned of the breach, the company said that it took immediate steps to secure that portion of its network. An investigation into the incident is ongoing.
