Updated: Signature Systems has release a list of 100 more independent restaurants using its systems that were compromised. See the store list - minus the Jimmy John's locations available below - here.
The hits just keep on coming for major retailers and restaurant chains. Fast food sandwich shop Jimmy John's has just confirmed that credit and debit card numbers, cardholder names and security codes were stolen from hundreds of its locations.
The data breach occurred between June 16, 2014 and September 5, 2014. It happened when hackers stole login credentials from Signature Systems, Jimmy John's point-of-sale system supplier.
From there, it was easy for hackers to install a virus that captured credit and debit card swipes. If you'll recall, many of the major data breaches recently - Home Depot, Target, Goodwill and others - have happened because of compromised POS systems.

Unlike Home Depot, where all 2,200 stores were hit, Jimmy John's only had a fraction of its stores hit. So if you've visited a location recently, your information might still be safe.
