Financial institutions inform of fraud on cards used at Jimmy John’s

The sandwich chain Jimmy John’s is currently conducting an investigation to find out if their payment systems have been compromised by malware and if customer credit and debit card data has been stolen.

Following reports from financial institutions that fraudulent activity involving credit cards used recently at Jimmy John’s locations has been recorded, the company has deployed its own internal analysis of the payment systems.

Security blogger Brian Krebs learned about the fraud from multiple financial institutions, and after contacting Jimmy John’s for a statement, he received news that authorities had been called in to help with the investigation and that an update would be provided.

There is no information on the number of customers that may be affected by the alleged breach, but Jimmy John’s has more than 1,900 locations spread all over the United States.

Most of them are franchises, which means that there is no centralized payment system available, but the common denominator is that they use a particular type of point-of-sale (POS) system that is the recommended standard.

The risk for the potentially affected users is that their cards could be cloned by cybercriminals and used to make fraudulent purchases of goods that are then re-sold at a lower price.
