Last week, the Tex-Mex restaurant chain On the Border suffered a data breach that impacted its payment acceptance systems in 27 states. The restaurant says that some credit card information of customers who visited the chain between April and August 2019 may have been compromised. In a press release, On the Border representatives said, “Our company has retained a leading forensics firm and is currently investigating the extent to which information in On the Border’s systems has been impacted. We are cooperating with law enforcement and have also notified payment card networks of the investigation.”

The states that have impacted restaurants include Arizona, Arkansas, Colorado, Connecticut, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, and Virginia.

The breach resulted from malware being installed on a payment processing system that accessed customer credit card data. This incident did not affect all customers or all catering orders. On the Border has taken steps to contain and remediate the breach.
