Jimmy John's full statement:
On July 30, 2014, Jimmy John's learned of a possible security incident involving credit and debit card data at some of Jimmy John's stores and franchised locations. Jimmy John's immediately hired third party forensic experts to assist with its investigation.
While the investigation is ongoing, it appears that customers' credit and debit card data was compromised after an intruder stole log-in credentials from Jimmy John's point-of-sale vendor and used these stolen credentials to remotely access the point-of-sale systems at some corporate and franchised locations between June 16, 2014 and September 5, 2014. The security compromise has been contained, and customers can use their credit and debit cards securely at Jimmy John's stores.
Approximately 216 stores appear to have been affected by this event. Cards impacted by this event appear to be those swiped at the stores, and did not include those cards entered manually or online. The credit and debit card information at issue may include the card number and in some cases the cardholder's name, verification code, and/or the card's expiration date. Information entered online, such as customer address, e-mail, and password, remains secure. The locations and dates of exposure for each affected Jimmy John's location are listed on http://www.jimmyjohns.com.
Jimmy John's has taken steps to prevent this type of event from occurring in the future, including installing encrypted swipe machines, implementing system enhancements, and reviewing its policies and procedures for its third party vendors.
