Politicians and trade groups renewed their call for more to bedone in the wake of the Target data breach after the company said Friday that far more damage may have been donethan originally reported.

The Minneapolis-based retailer announced that personalinformation such as emails such as mailing addresses, phone numbersand email addresses, were also compromised when the card data wasapparently hacked between Black Friday and Dec. 15.

As many as 70 million people may have had their data stolen, upfrom an earlier estimate as 40 million debit and credit accountsthat were compromised, the company said in Friday'sannouncement.

The company's announcement noted that it was offering identitytheft protection and free credit reports to affected consumers andthat Target shoppers would not be held personally liable for cardlosses.

NAFCU responded Friday by renewing its call for congressionalaction on data security.

“The latest revelation of compromised consumer records wellillustrates NAFCU's case for setting a statutory requirement formerchants' protection of consumer data. Merchants and big-boxretailers must be accountable for data breaches originating ontheir end,” President/CEO Dan Berger said in a statement.

“Credit unions and other financial institutions aren't theproblem. There are ample rules in place to ensure data protectionstandards at financial institutions. Still, consumers and smallfinancial institutions – including credit unions – are picking upthe tab for retailers. Until a legislative fix is put in place,consumers' sensitive financial and personal data will continue tobe at risk.”

Sen. Patrick Leahy (D-Vt.) on Wednesday reintroduced a bill that would create a national standard thatbusinesses would have to follow for informing customers about asecurity breach. It would also require companies collectingpersonal information from customers to meet certain dataprotections standards.

New York's attorney general, Eric T. Schneiderman, also put outa statement following Friday's announcement.

“The news that Target has discovered a breach involving 70million customers is deeply troubling. Consumers in New York andaround the country expect and deserve companies that protect theirpersonal information when they shop on their websites and in theirstores,” he said.

“That is why my office is participating in a nationalinvestigation into this breach, why I pressed Target to providefree credit monitoring for the 40 million Target customersidentified last month, and why I insist it extends the same serviceto every new victim,” his announcement said.
