Chili's restaurant chain is the latest company to suffer a data breach.
The bar and grill released a statement on Saturday informing customers of a "data incident."
The company believes it is limited to between March and April 2018 and only for in-restaurant purchases.
Chili's did not go into detail about which of the corporate-owned restaurants were affected, nor how many people may have been impacted.
In a statement, Chili's said they believe malware was used to gather payment card information, and that they are working with third-party forensic experts and law enforcement.
