Cydia Impactor uses vulernability to root Android devices including Google Glass


Gaining root access to any Android device can be a complex route of ¬†firmware flashing that is often ‘horses for courses’, relying on different techniques for different Android devices.

Cydia Impactor is different. Using what’s known as the Android ‘Master Key’ vulnerability, Cydia Impactor is a ‘work in progress’ Windows or MacOS X app that allows you to gain root access to most Android device,¬†including Google Glass, by simply connecting it up to your computer and running this app.

To use the app, you’ll likely need the ADB drivers if you’re using Windows – this allows the PC to talk to your Android device. The Cydia Impactor website has all the details plus links to various drivers. It can also scan the USB for devices that are not automatically listed.

While most devices are not patched yet for the vulnerability, there is a second method Cydia Impactor tries to use. However, there are some devices which have been effectively ‘double patched’ and this app will not work on those devices with certain combinations of Android OS – they include the Motorola Atrix 4D with Android 4.1.1, Huawei’s Ascend Mate with Android 4.1 and the HTC One with Android 4.2.2.

The Master Key vulnerability was found by Bluebox Security and according to Cydia Impactor, the security firm as an app that will help you know whether Cydia Impactor will work. has given the app a try but while it didn’t work on an MK908 or Tronsmart T428 mini PC, another reader had success with a Mediatek MTK6577 smartphone and a Rockchip RK3066 tablet.

So if you want root-access on your Android device but you’re looking for a simpler solution to make it work, Cydia Impactor could well be worth a look.
