It’s worth noting that Gingerbread is by far the most used Android OS, with 50 percent of all Android devices running it. That could explain why it is also the most attacked operating system. “Android 2.3.6 ‘Gingerbread, which accounts for 28 percent of all blocked attempts to install malware, was the most commonly attacked version. It is not new: it was released in September 2011. However, due to the considerable segmentation of the Android device market, it remains one of the most popular versions,” Kaspersky Lab adds.
