Zen Cart “PayPal” Skimmer

From blog.sucuri.net

While we mostly see skimmers on Magento based websites, this does not mean that less-popular ecommerce platforms are safe from infections with similar payment information stealing malware.Our security analyst Christopher Morrow recently found an injection on a lesser known open source ecommerce platform named Zen Cart, which itself is a fork from the older OsCommerce. Credit card skimmers are not found as often for Zen Cart. This is because the Zen Cart user base is quite small (0.1%) when compared to other open source platforms like Magento (0.8%) or Prestashop (0.6%) – according to W3’s latest information.
