Many merchants rely heavily on point-of-sale payment card processing, and for them it’s certainly not news that enterprising criminals sometimes target these systems to steal sensitive data. It’s important to keep in mind that these types of attacks are not static in nature—the general advance of technology tends to result in comparable enhancements in malware and similar threats.
There are reports circulating that a new Trojan aimed at POS systems utilizing Microsoft Windows is wreaking havoc in the wild, stealing valuable data. Called “vSkimmer,” this malware steals the “track 2” data normally encoded within a card’s magnetic stripe.
The arrival of vSkimmer is another reminder of the need for merchants to continually optimize their security systems by applying relevant patches and antivirus updates as soon as these are made available. Keeping your POS up to date with security patches will not only minimize security risks but ensure compliance with the PCI Data Security Standard (PCI DSS).
