Hacker shows Flying JB, a jailbreak for iOS 9.2.1

We are not seeing public tools to jailbreak the latest versions of iOS, but we have already seen some accounts showing that it is possible to break the chains of our iPhone, iPod Touch or iPad. Until now it was the hacker Luca Todesco who kept giving us long teeth, but now it has been SparkZheng who has shared a video in which he shows a tool that has called Flying jailbreak, but that only works on 32-bit devices running iOS 9.2.1.

The case of Flying JB is similar to the tool that Pangu launched in March and that allowed jailbreak devices> iOS 9.1 when iOS 9.2 was already available. It is similar because a jailbreak has been released for a previous version and because it has used a vulnerability in the HeapOverflow kernel that existed for more than 15 years and that Apple fixed in iOS 9.3.2, but it is not exactly the same because SparkZheng has not released a simple tool to perform the process.

Flying JB on video

If you want to use Flying JB you will have to use its source code. In its GitHub page is available, as well as the instructions to install it, a process performed using a terminal which is installed in the first steps. With no simpler tool available, Actualidad iPhone does not recommend its installation. In fact, the demo video ends and we don't even see Cydia installed on her device, so to me it looks like a demo that stops halfway. On the other hand, a well-done demo is done by recording the entire phone, not its screen with QuickTime or some similar tool.

What strikes me about this story is that a kernel bug that existed since 2001. In the year in which the original iPod was introduced, there was still no OS X (OS 9 was still used), needless to say that there was still time for us to see a first version of iPhone OS that, as you all know, would later become be called iOS. That they have corrected this bug makes me think that hackers from the jailbreak scene that Apple has hired, such as winocm, are doing a good job and apple operating systems are increasingly secure. Of course, it does not seem like good news for the jailbreak in general.
