Alert Priority Moderate

As the 2014 festive season continues and post-Christmas sales draw nearer, retailers need to protect themselves and their customers against malware targeting Point of Sale (PoS) systems.

PoS systems capture and process credit and debit card information when consumers purchase goods and services from retailers. PoS malware aims to steal this information – comprising details such as the card number, expiry date and cardholder’s name – as it is entered into PoS systems. Criminals sell the information or retain it to create fraudulent credit and debit cards, which can be used to make purchases or empty consumers’ accounts.

More sophisticated PoS malware can target retailers themselves by introducing falsified data or by accessing other critical systems on the same network.

We recommend that retailers ensure their PoS terminals and systems are secure and all software − including antivirus products − are up to date. Where possible, PoS computers should only be connected to required services.

Researchers believe common malware can be delivered to PoS systems through phishing emails or by taking advantage of default credentials to access systems remotely. There are many types of PoS malware and recent media reports indicate versions are being sold on online forums frequented by malicious individuals. Illegally obtained card details themselves are being sold from similar locations.
