New Android OS blocks some ransomware
New Android OS blocks some ransomware

Along with new features, Google's latest iteration of its mobile operating system for Android devices, Android O, blocks ransomware, at least malware using system-type windows, according to a post on Symantec's Security Response blog.

Most ransomware draws a system-level window so the locked screen appears to float on top of the other windows, thus making the device unusable until a ransom is paid. The upgrade to Android O deprecates some system-type windows, the report stated.

There might be a problem, though, for users without the latest version of Android. Those with older versions could still be at risk for a ransomware attack launched by this method, as well as other forms of ransomware.

Symantec had the following recommendations:

  • Keep your software up to date
  • Refrain from downloading apps from unfamiliar sites and only install apps from trusted sources
  • Pay close attention to the permissions requested by apps
  • Install a suitable mobile security app to protect your device and data
  • Make frequent backups of important data.
