Android is currently the largest mobile platform with around 750 million devices worldwide. Unfortunately, more than 30% of all devices contain publicly known security vulnerabilities and, in practice, cannot be updated through normal mechanisms since they are not longer supported by the manufacturer and mobile operator. This failure of traditional patch distribution systems has resulted in the creation of a large population of vulnerable mobile devices.
