Android wallpaper app that steals your data was downloaded by millions | VentureBeat

“Even good apps can be modified to turn bad after a lot of people download it,” MaHaffey said. “Users absolutely have to pay attention to what they download. And developers have to be responsible about the data that they collect and how they use it.”

The app in question came from Jackeey Wallpaper, and it was uploaded to the Android Market, where users can download it and use it to decorate their phones that run the Google Android operating system. It includes branded wallpapers from My Little Pony and Star Wars, to name just a couple.

That assumes that users could get it to work with their Android phone.
