Let me remind you that we also wrote that SharkBot Trojan Again Infiltrates the Google Play Store.

As the name implies, Facestealer is designed to steal logins and passwords from Facebook accounts, which are then used by attackers for phishing, publishing fakes, and as advertising bots.

As Trend Micro now reports, some of the apps they found have been installed over 100,000 times.

The report notes that Facestealer-infected apps often look like photo editing, processing, or sharing tools, but can also take other forms. For example, researchers talk about Daily Fitness OL, which is advertised as a fitness app with exercises and video tutorials.

One of the apps we found, named Daily Fitness OL, claims to be a fitness app, complete with exercises and video demonstrations. But like the initial variant, it was designed to steal the Facebook credentials of its users.Trend Micro specialists write.

This fake fitness app prompts users to log in to Facebook through the built-in browser, and then a JavaScript code is “injected into the loaded page to steal the credentials entered by the user.”

After the user successfully logs in to an account, the app collects the cookie. The spyware then encrypts all the personally identifiable information (PII) and sends it to the remote server. The encryption key and address of the remote server are all taken from the downloaded configuration.researchers report.
Other apps infected by Facestealer found by Trend Micro are: Enjoy Photo Editor, Panorama Camera, Photo Gaming Puzzle, Swarm Photo, and Business Meta Manager.
