Food chain, PF Chang’s, investigates possible card breach

A large batch of stolen credit card numbers for sale on an underground forum may have come from a breach at P.F. Chang’s China Bistro, a restaurant chain that said on Tuesday it is investigating.

Those selling the stolen data are claiming all of the card numbers are still valid, meaning the data is fairly fresh and that banks haven’t yet canceled the accounts, said Alex Holden, CTO of Hold Security, a Wisconsin-based consultancy that monitors secret forums where stolen data is sold.
