According to KrebsOnSecurity.com, Jimmy Johns aren’t the only restaurants to get caught in this breach, which lasted from June 16 through mid-September (dates vary at some locations). Many small restaurants use Signature Systems PDQPOS point-of-sale systems. A total of 216 Jimmy Johns and 108 other restaurants are affected because “an authorized person gained access to a user name and password that Signature Systems used to remotely access POS systems.” This access allowed the attacker to install malware to steal payment card data, containing the cardholder’s name, card number, expiration date, and verification code from the magnetic stripe of the card.

I wonder if Signature Systems changed their passwords on a regular basis? Probably not. Did they use two-factor authentication? Long and strong passwords? Did they conduct employee training on anti-phishing techniques?

Unfortunately, as of October 28, 2013, PDQPOS was only acceptable for pre-existing deployments. So it’s possible that some of these restaurants may receive fines if the system was installed after that date.
