The term Cydia is usually associated with devices running iOS, more so with the jailbroken ones. Cydia is like a 3rd party store which houses tons of tweaks, mods and apps for jailbroken iOS devices. Well, it so happens that iOS is not the only ecosystem that saurik, the dude behind Cydia, is giving his attention to. Earlier this year, Bluebox security announced the existence of a Master Key exploit for Android devices , which was considered a high-severity vulnerability that affected almost 99% of Android devices.
Saurik has not only patched this vulnerability, but also released a new tool called Cydia Impactor that can be used to root any Android device, or at least 99% of them which were potentially vulnerable to this exploit. The tool should work up through devices running Android 4.1.x Jelly Bean, possibly higher versions too, and will also work for Google TV and Google Glass. The cool thing about this tool, is that if it is not able to root your device via the Master Key bug, it will automatically attempt to achieve root through a different signature verification bug. Cydia Impactor is available for Windows, Linux as well as Mac. Here’s how you can use Cydia Impactor to root any Android device.

At last count, the tool has been reported not working with three devices/Android versions – Motorola Atrix 4D on 4.1.1, Huawei Ascend Mate on 4.1, and HTC One on 4.2.2, but won’t harm the devices any.
