PF Chang's latest card breach victim

In the latest national credit card breach, P.F. Chang's China Bistro is looking into claims of a data breach involving credit and debit card data reportedly stolen from its 204 restaurant locations nationwide.

On June 9, thousands of newly-stolen credit and debit cards went up for sale on rescator[dot]so, an underground store best known for selling tens of millions of cards stolen in the Target breach, KrebsonSecurity reported. Several of the cards had been used at P.F. Chang's locations between the beginning of March 2014 and May 19, 2014.

"P.F. Chang's takes these matters very seriously and is currently investigating the situation, working with the authorities to learn more," the company said in a statement emailed to KrebsonSecurity. "We will provide an update as soon as we have additional information."

P.F. Chang's is just the latest victim of credit card breaches that have impacted Target (NYSE: TGT), Neiman Marcus and Sally Beauty (NYSE: SBH). Payments processor ACI Worldwide said the impact could be larger than the Sally Beauty breach.

"There is continued focus from the hacker community on American merchants as we are still the softest target to exploit and monetize. Until we take the necessary efforts to get control around the management of payment card data in the merchant channel through technologies like EMV and tokenization, we will continue to be impacted," Seth Ruden senior fraud consultant at ACI Worldwide, said in a statement emailed to FierceRetail. "The best defense against these attacks is through the development of our own networks and communities: information sharing and internal discussion of threats/actors to develop coordinated strategies."
