Many of you who are following Anonyviet must be using many mobile devices from the apple house, right? So you must have at least once heard the phrase Jailbreak, right? And just like the title says, I will show you how to jailbreak your device so you can do more things!
What is Jailbreak?
Up to this point, I still receive a series of questions about Jailbreak. So to summarize, Jailbreak is the process of removing software barriers imposed by Apple on iOS, tvOS and IpadOS. Because Apple’s operating system is closed source, with many restrictions on customizing the interface to the user’s own preferences as well as installing special applications that are not available on the App Store. Jailbreak can be roughly understood as Root on Android phones.
When you jailbreak, you can customize and customize the available functions and remove default applications like Safari on iPhone. For a specific example, as you all know, chat bubbles only exist on Android, right (currently only a minority of devices from apple house can open chat bubbles in beta mode)? Then when you jailbreak, you can customize to display chat bubbles or even display your own chat bubbles.
Although the benefits are many, the harms are equally many. When you jailbreak any device, you will lose the warranty for your device and will have an increased rate of information theft from users because when the operating system is open, there are many risks that Hackers will benefit. use the vulnerability to access your device and steal information like your name, phone number or even access the camera and invade your privacy. So before Jailbreak, you should consider the advantages and disadvantages to avoid regret later
Currently, there are two versions of Jailbreak, Tethered and Untethered. For the Tethered version, the device is only temporarily jailbroken until you restart the device. This method is quite popular today and is used by many people to “break” the device temporarily. As for Untethered, you only need to run the tool once and the device will be jailbroken forever. Both methods mentioned above can void the warranty and increase security risks!
Fugu14 is an iOS 14 Jailbreak (not yet complete guys), including an Untethered method as I mentioned above, kernel exploit (kerel exploit), kernel PAC bybass and PPL bybass. The CVE numbers of the vulnerabilities used are: CVE-2021-30740, CVE-2021-30768, CVE-2021-30769, CVE-2021-30770, and CVE-2021-30773.
Fugu14 currently only supports devices including iPhone XS, XS Max, XR, 11, 11 Pro, 11 Pro Max, SE (2020), 12, 12 Mini, 12 Pro and 12 Pro Max along with some devices. iPad. Supported iOS versions are from iOS 14.4-14.5.1. In the future the tool will support more iOS devices and versions (according to the developer).
