An app claiming that it can change the color of your Facebook profile page actually loads malware onto your smartphone or computer. According to a Cheetah mobile security blog post, more than 10-thousand people around the world have been duped.
When Facebook users click on the fake app, it sends them to a malicious website that asks them to watch a tutorial video about how to change the color of their profile page. By agreeing to watch the video, the users give hackers access to their profiles, letting the app spam their friends.
Facebook color changer scams have been around awhile. It's generally a good idea to avoid anything purporting to change the color of your profile.
