(KGTV) - Chili’s is warning customers Friday about a possible payment card data breach at restaurants. The chain says malware was used to gather payment card information including credit or debit card numbers and cardholder names. Expiration dates and CVV codes on the back of cards may also have been accessed at certain Chili’s restaurants. The data were accessed between March and April of 2018, but Chili’s says a breach may have occurred on other dates. Chili’s said affected customers would have access to MyIDCare , a fraud resolution and credit monitoring service. It provides credit monitoring, a $1,000,000 insurance reimbursement policy, exclusive educational materials, and fully managed identity theft recovery services. The chain is working with third-party forensic experts to determine the scope of the problem. Customers can call 888-710-8606 for more information.
