New Android Operating System Blocks Certain Ransomware


The first developer preview of Google’s latest mobile operating system, Android O, has been released. As usual, the newest version of Android has several new features and updates. One of those updates has a direct impact on many Android ransomware threats. Android ransomware using system-type windows will no longer work on devices running Google’s latest mobile operating system, even if the relevant permission has been granted by the device’s user.

Android O has deprecated the following window types:
  • TYPE_SYSTEM_ALERT
  • TYPE_SYSTEM_ERROR
  • TYPE_SYSTEM_OVERLAY
 
In Android O, even if the malware draws the TYPE_SYSTEM window, the user can pull down the system settings from the top of the screen and “TURN OFF” the app causing the trouble.
