Malvertising attack silently infects old Android devices with ransomware

Lucian Constantin | April 26, 2016
The Web-based malware attack uses Towelroot and a Hacking Team exploit to compromise devices running old versions of Android.

However,  because malware creators can use such exploits for malicious purposes, Google views rooting apps as potentially harmful and blocks their installation through an Android feature called Verify Apps. Users should turn on this feature under Settings > Google > Security > Scan device for security threats.

Upgrading a device to the latest Android version is always recommended because newer versions of the OS include vulnerability patches and other security improvements. When a device goes out of support and doesn't receive updates anymore, users should limit their Web browsing activities on it.

On older devices, they should install a browser like Chrome instead of using the default Android Browser.
