Illinois-based sandwich shop Jimmy John's alerts its customers regarding a credit and debit card hack at some of the store's branches.
Sandwich shop giant Jimmy John's warned the public yesterday about a possible security problem affecting credit and debit cards used in some of Jimmy John's branches in the United States.
News came to Jimmy John's on July 30 of a suspected hacking in 216 Jimmy John's locations including branches in North Carolina, Greensboro and Kernersville.
More than 12 of the affected branches originate from the Chicago area.
A hacker allegedly penetrated the system and stole the log-in information that includes the card number, cardholder's name, verification code and/or card's expiration date from the company's Point-of-Sale vendor and used the stolen credentials to remotely access the POS systems at corporate and franchised locations between June 16 and Sept. 5.
Jimmy John's reported to have resolved the issue, and informs customers that their credit and debit cards can now be used in all of the sandwich shop's branches without fear of security breach.
According to Jimmy John's official statement regarding the incident, the cards that were affected were the ones swiped at the stores and did not include the cards entered manually or online.
Furthermore, data accessed online which includes information such as customer address, e-mail and password are reported to remain secure.
To prevent similar incidents from happening in the future, Jimmy John's has installed encrypted swipe machines, improved the systems and re-evaluated the store's policies and procedures for third party vendors.
Aside from that, Jimmy John's also offered customers affected by the incident identity protection services.
Home Depot has reported a similar incident involving what seems to be the biggest data breach in retail history with 56 million credit cards hacked by a malware and involving U.S. and Canadian Home Depot stores.
