"CiCi’s Pizza, an American fast food business based in Coppell, Texas
with more than 500 stores in 35 states, appears to be the latest
restaurant chain to struggle with a credit card breach. The data
available so far suggests that hackers obtained access to card data at
affected restaurants by posing as technical support specialists for the
company’s point-of-sale provider, and that multiple other retailers have
been targeted by this same cybercrime gang.
Over the past two months, KrebsOnSecurity has received inquiries from
fraud fighters at more than a half-dozen financial institutions in the
United States — all asking if I had any information about a possible
credit card breach at CiCi’s. Every one of these banking industry
sources said the same thing: They’d detected a pattern of fraud on cards
that all had all been used in the last few months at various CiCi’s
Pizza locations."
