Chipotle Mexican Grill Inc. reports financial results on Tuesday, April 26, 2016.
Chipotle reported back in April that they had detected "unauthorized activity" for its customer payment system and the company suggested that customers who have used credit cards at their stores between March 24 and April 18 of this year keep an eye on their accounts.
The fast-casual Mexican restaurant recently announced many of its locations across the country were hit by a malware attack that was created to get credit card data from point-of-sale devices from March 24 to April 18.
In a news release, Chipotle says those locations include franchises on Route 34 in Oswego, Orchard Road in Aurora, Sycamore Road in DeKalb, Randall Road in Geneva, Plainfield Road in Joliet, Route 59 in Naperville and South Route 59 in Plainfield. The company hasn't said how the malware penetrated its card-reading registers.
"Because of the nature of the incident and the data involved, we lack sufficient information to determine how many unique payment cards may have been involved", said company spokesperson Chris Arnold. However, the company was unable to identify all of the affected locations.
The company also created a hotline-888-738-0534-that customers can call with questions related to the incident.
Chipotle urges its customers to be proactive by reviewing credit card statements and free credit reports.
