People hungry for chicken lettuce wraps may have gotten more than they bargained for, as P.F. Chang’s is officially acknowledging that credit and debit card data from 33 restaurants were hacked between October and June.

News of the breach was first reported in June, when the Chinese restaurant chain was alerted to it by the U.S. Secret Service. In June, the restaurant operator admitted that its data had been breached, but said the investigation was ongoing. (More from Money.com: What to do in the event your personal data gets hacked)

In a statement, P.F. Chang’s president Rick Federico said that there have been no additional breaches since the company was contacted by the Secret Service. He also said that card numbers, names and expiration dates could have been stolen, though there is no way to know if any specific cardholder’s information was taken.
