Grocery story chain Schnuck Markets Inc. now says about 2.4 million debit and credit cards were likely compromised as a result of a breach of its point-of-sale network back in December (see Retailer Says 'Code' Compromised Cards).
In a statement and timeline of events issued April 15, Schnucks does not say exactly how its network was attacked. But the company confirms that malware designed to access card numbers was discovered on its network - ruling out the possibility that the breach resulted from POS-device tampering or an insider scheme. Schnucks also notes that transactions conducted between Dec. 1 and March 29 at 79 of its 100 stores were affected. Those stores are in Missouri, Illinois, Indiana and Iowa.
