ZDNet said: “The apps posed as step counters, image editors, video editors, wallpaper apps, flashlight applications, file managers, and mobile games.”
According to Evina, code hidden in the apps can detect which pages you’ve recently opened.
If this is Facebook, the app can overlay a web browser window on top of the official Facebook app and load a fake Facebook login page.
If you’re fooled by the fake page and enter your credentials, the app can log your data and send it to a remote server.
