A northeast Missouri man is the victim of that security breach at P.F. Chang??s restaurants.
The Chinese restaurant chain says credit and debit card information may have been stolen from 33 restaurant locations.
The majority are located in California, with the rest scattered around the U.S.
Hector Contreras of Kirksville told KTVO his bank's fraud detection department notified him over the weekend that his account had been hacked.
He had dined at P.F. Chang's on the Plaza in Kansas City a few months ago.
Contreras said the criminals used his debit card information to make more than $1,000 in purchases, all at a Kroger grocery store in Atlanta, Georgia.
Luckily, his losses were covered by his bank.
P.F. Chang's first found out about the data breach on June 10, 2014, when it was alerted by the Secret Service.
The time frame for the potential theft dates as far back as October of 2013.
P.F. Chang's is providing free identity protection services for those who may have been affected, and the chain is continuing to investigate the situation.
The company said that it is now safe for customers to use credit and debit cards at its restaurants.
