Jimmy John's is the latest national company affected by a potential credit and debit card data breach.
According to thecompany's Wednesday announcement, it was informed of the possible breach on July 30. An investigation involving third-party experts began immediately, the company said, but it appears that customer information remained exposed during that investigation.
The company believes the 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."
Two-hundred sixteen stores, where customers swiped their cards, were affected by the breach. Information exposed might include the card number and in some cases the cardholder's name, verification code, and/or the card's expiration date, the company stated.
