(Richmond, IN)--If you ate at Chipotle earlier this spring, your account information may have been compromised. Malware designed to access payment card data from cards used was discovered during a nationwide investigation. The Richmond Chipotle was named as a store that was victimized between March 25 and April 18. The store in Oxford was also targeted over the same dates. Experts say that if you were a Chipotle customer between those dates, you should check your account carefully for unauthorized activity.
