Schnucks grocery store chain says as many as 2.4 million credit and debit cards were compromised. Only the numbers and expiration dates of the cards could have been accessed. No other customer data — such as names and addresses — was taken, the company says. Schnucks has implemented a containment plan and admitted the attack. The company has worked with the payment processor to make sure any card numbers potentially affected were sent to the credit card companies so that they may send alerts to the issuing banks.”]
