Have you eaten at P.F. Chang's lately? If so, you might want to go over your credit-card statement carefully, because the restaurant chain has been hacked.

33 locations suffered data breaches between October 2013 and this past June. Company officials believe the hacker may have gotten a hold of credit card numbers, expiration dates and cardholder names. But they can't say for sure if any data was stolen.

Word of the breach actually came down in June -- yesterday's disclosure simply confirms the breach and clarifies where it occurred.
