tsu doh nimh writes: Nationwide chain P.F. Chang’s China Bistro said Tuesday that it is investigating claims of a data breach involving credit and debit card data reportedly stolen from 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. Several banks contacted by KrebsOnSecurity said they acquired from this new batch multiple cards that were previously issued to customers, and found that all had been used at P.F. Chang’s locations between the beginning of March 2014 and May 19, 2014.The ad for the Ronald Reagan batch of cards also includes guidance for potential customers who wish to fund their accounts via Western Union or MoneyGram wire transfers, advice that strongly suggests those involved in this apparent heist are once again from Russia and Eastern Europe: "Western Union transfers will be received in the next 48-72 hours! Money Gram transfers will be received 10-11 of June. Please note: 12, 13, 14, 15 of June are the government holidays in the drops country and Money Gram transfers will be received starting Monday June 16th." June 12 is "Russia Day," a national holiday in Russia since 1992 that celebrates the declaration of state sovereignty of the Russian Soviet Federative Socialist Republic on June 12, 1990.
