Target and Neiman Marcus said payment card terminals were infected with malicious software that collected payment card details. Target said up to 40 million credit and debit cards were stolen; Neiman said 1.1 million cards may have been affected. Some of the data became available in underground cybercrime forums after it was stolen from point-of-sale devices.”]
