A researcher has uncovered new malware that steals payment card data from point-of-sale terminals used by stores, hotels, and other businesses.
Dexter, as the malware is called, has infected hundreds of point-of-sale computers at big-name retailers, hotels, restaurants, and other businesses, according to a report issued by Aviv Raff, chief technology officer of Israel-based security firm Seculert. Businesses infected in the past three months are located in 40 different countries, with 30 percent of those compromised located in the US, 19 percent in the UK, and nine percent in Canada. Malware that infects point-of-sale terminals can be one of the most efficient ways to carry out payment card fraud because it targets machines with access to large amounts of the required data.
"Instead of going through the trouble of infecting tens of thousands of PCs or physically installing a skimmer, an attacker can achieve the same results by targeting just a few POS systems with specially crafted malware," Raff wrote. "Dexter is one example of such malware."
