Yellowfront Grocery Store Data Breach Week 10

For week 10 a grocery store in Damariscotta, Maine was the victim of a data breach. The Yellowfront Grocery store was a victim of ram scraping malware. This is the same type of malware that was used in the target breach.  If you think that peoples credit or debit cards are safe at a grocery store think again.

The Yellowfront Grocery store is unsure how many peoples payment cards were stolen during the breach. They have said that over 3,000 cards have been replaced by two different banks, because of the breach at their store. They said that only the track 2 data from cards, which contains card numbers and expiration dates and that no cardholder data was comprised (Abel, 2015). Track 2 data contains the cardholder's account, encrypted PIN, plus other discretionary data (Magnetic Stripe Track 1, Track 2 Data Description). The ram scraping malware was able to steal the data before it was encrypted. It was not said if it was on multiple point of sale or POS systems or just one centralized POS system. The Yellowfront Grocery believes the attacker accessed his store's payment system by logging into it through CSTARS's compromised system (Abel, 2015). They believe that the breached happened between August 11 and October 16, 2015. Since only credit and or debit card information was stolen there is no need for credit monitoring. It is a good thing that banks are replacing every person’s card that was used in the store on those affected dates.

This ram scraping malware is very dangerous software. Once a system is affect it will steal card information out of the computers random access memory or RAM before it gets encrypted to be sent off to the payment processor. This is why it is important that stores and credit card companies work together to encrypt the data through the whole transaction. Any store that processes credit and or debit cards needs to make sure there network is secure. Grocery stores will need to check their security by hiring a contractor or security professional to assess their risk.
