Google has kicked out 13 Applications from the Play store which were part of a malware chain called Brain test. These apps looked just like normal ones but would gain root access on the device and also helped install other malware infected apps on the same device without the user’s knowledge. All the 13 apps were games and so it was easy to get the users install them on their devices.
The 13 apps listed above would create reviews on the Google Play store to lure other users into installing the apps. Once installed, even a factory reset of the devices would not removes these apps. The user could only remove these malware apps by flashing a new build of the OS from a factory image.
It is reported that the motive behind these apps is money where the hackers promise a specific number of installations to the developers and with the help of these malware infected apps, they would increase the number of devices where apps are installed.
