Credit and debit card information may have been stolen from customers who dined at the P.F. Chang's China Bistro at Woodfield Mall between April 10 and June 11, company officials said this week.
The Schaumburg location is one of 33 restaurants nationwide where data from cards -- including card numbers, cardholder names and card expiration dates -- may have been stolen, the company announced in a news release.
The U.S. Secret Service alerted P.F. Chang's to the possible security compromise on June 10. The compromise was contained, and the restaurant has been processing credit and debit card data securely since June 11, officials said.
Investigators, including third-party forensics experts, are still working to "understand the nature and scope of the incident," and the investigation is ongoing, officials said. They haven't determined that any specific cardholder's credit or debit card data was stolen.
The Schaumburg restaurant is the only P.F. Chang's in Illinois to be identified as being a potential part of the breach, which includes restaurants coast-to-coast from as early as Oct. 19, 2013, to June 11.
Company officials said other restaurant locations affected by the breach may be identified during the investigation. A list of the 33 restaurant locations is available at pfchangs.com/security.
P.F. Chang's has established a hotline to answer questions from those who believe their information may have been stolen. The hotline, available 8 a.m. to 8 p.m. Monday through Saturday, is (877) 412-7152.
