On Wednesday the nation-wide sandwich chain Jimmy John’s admitted that have become one of the latest victims of hackers. The security breach took place from June 16 to September 5 of this year compromising the payment system in 216 of the 1,900 stores stores. The breach allowed the perpetrators to download the information of credit and debit cards that were swiped through the electronic card scanners.
The Illinois-based sandwich chain was first notified in July when banks noticed unusual activity on the card’s of customers that recently made a purchase. Brian Kerbs became aware of the problem shortly after Jimmy Johns was notified and reported in a July 31 post on his blog KrebsonSecurity. That was when the company took action by hiring a security firm to start an investigation that is still going.
The malware that caused the breach was eradicated from the 216 stores on September 5, 2014. Jimmy John has offered ID protection for all customers that might have fallen victim to the thieves.
“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,” they wrote in the statement released on the breach.
“My first suggest is a prepaid card nearly fee free and comes with many features at no additional cost,” said former hacker turned cyber security expert Gregory Evans when he was asked about this type of breach on the Hallmark channel’s talk show Home & Family. In the interview on the show Mr. Evans also talked about using smartphone payment systems that can also add an additional level of security by encrypting your credit card information.
The only the credit and debit cards that were compromised were the ones run through the infected scanners and not ones that were entered by hand. So, having the clerks psychically punch in the number of your credit or debit cards could help you from being a victim. The best way of prevention though is to use cash for your purchases.
