Global restaurant brand P.F. Chang's China Bistro is investigating a possible data breach that could have exposed thousands of diners' credit and debit card data.
A new listing on rescator.so, an underground site known for selling card numbers, is advertising the availability of thousands of newly acquired credit and debit cards, according to technology blogger Brian Krebs. Krebs investigated the listing and found that all the cards had been used at the Chinese restaurant chain between March 2014 and May 19, 2014.
P.F. Chang's is coordinating with law enforcement and banks to determine the source of the card data.
The new listing is selling magnetic stripe data that could be re-encoded onto cards. Typically, this data is acquired through point-of-sale (POS) system attacks.
