P.F. Chang's China Bistro Inc. has provided new details about a security breach discovered in June, saying customer data may have been stolen from 33 restaurants in 16 states, according to the Los Angeles Times.

In the attack, credit card numbers, expiration dates and, in some cases, cardholder names were stolen during an eight-month period. CEO Rick Federico said it hasn't been determined if any specific cardholder's credit or debit card data was stolen.

The company said the breach occurred between Oct. 19, 2013, and June 11, 2014.

Two Missouri restaurants were affected: one in St. Louis and another in Chesterfield, according to the chain's security list.
