48 percent of all these malicious apps are premium service abusers, followed by 22 percent that are adware and a 21 percent of data stealers. Malicious downloaders are offered in 19 percent of the cases, while rooters, click fraudsters and spying tools are at the bottom of the ladder.
The apps are pushed onto users through third-party online stores and even the official Google Play app store - despite filtering and scanning efforts from Google itself. More often than not masquerade as legitimate and popular software such as Angry Birds, Skype and Instagram.
