Mobile security firm Lookout has found more than 20,000 samples of rogue versions of popular Android apps. They’re fully functional copies of popular apps like Candy Crush, Facebook, Google Now, NYTimes, Okta, SnapChat, Twitter or WhatsApp. The goal of these rogue apps is to aggressively display advertisements on devices. Unlike traditional adware, they root the devices where they get installed in order to prevent users from removing them. The attackers behind these threats likely uses automation to repackage the most popular legitimate apps from Google Play.”]
