Banks Sue Target, Security Firm Over Breach

Target Corp. and Trustwave Holdings Inc., which provides credit card security services, have been sued by two banks for "monumental" losses they say card issuers will face because of the retailer's holiday season data breach. In a complaint filed in Chicago federal court, Trustmark National Bank and Green Bank NA accused the defendants of failing to properly secure customer data, enabling the theft of about 40 million payment card records plus 70 million other records, including addresses and phone numbers.
