Fugu: The First Open Source Jailbreak Based on the Checkm8 Exploit
If you are an iOS user who loves to customize your device and explore its full potential, you might be interested in Fugu, the first open source jailbreak tool based on the checkm8 exploit. In this article, we will explain what Fugu is, how it works, and
how you can use it to jailbreak your iOS device.
What is Fugu?
Fugu is a jailbreak tool that allows you to gain root access to your iOS device and install unauthorized apps and tweaks. Unlike most jailbreak tools, Fugu is based on the checkm8 exploit, which is a hardware-based vulnerability that affects all iOS
devices with A5 to A11 chips. This means that Fugu can jailbreak any iOS version from iOS 12 to iOS 15 on supported devices, and that Apple cannot patch the exploit with software updates.

How does Fugu work?
Fugu works by exploiting a flaw in the bootrom of the iOS device, which is the first piece of code that runs when the device is turned on. By sending a specially crafted USB command to the device in DFU mode, Fugu can inject its own code into the bootrom
and take control of the device. This allows Fugu to bypass the security checks that prevent unsigned code from running on the device.
Once Fugu has gained control of the device, it can install a custom bootloader called iStrap, which allows Fugu to load a custom kernel and run any code it wants. This includes installing Sileo, SSH and Substitute, which are essential components for
jailbreaking. Sileo is an alternative app store that lets you download and manage jailbreak apps and tweaks. SSH is a protocol that lets you remotely access your device's file system and execute commands. Substitute is a library that enables code
injection and modification for jailbreak tweaks.
How to use Fugu?
To use Fugu, you need a supported device running a supported iOS version (see below), a computer with Xcode installed, and a USB cable. You also need to download the latest version of Fugu from its GitHub repository (
https://github.com/LinusHenze/Fugu).
Here are the steps to follow:
Put your iOS device into DFU mode by following the instructions for your device model (
https://www.theiphonewiki.com/wiki/DFU_Mode).
Connect your iOS device to your computer with a USB cable.
Open a terminal window and navigate to the folder where you downloaded Fugu. Run ./Fugu iStrap and wait for Fugu to exploit your device and install iStrap. Unlock your iOS device and follow the on-screen prompts to install Sileo, SSH and Substitute.
Congratulations! You have successfully jailbroken your iOS device with Fugu.
Supported Devices/iOS Versions
Fugu supports all iOS devices with A5 to A11 chips, which include:
iPhone 4S to iPhone X
iPad 2 to iPad Pro (10.5-inch)
iPad mini 1 to iPad mini 4
iPod touch 5th to iPod touch 7th generation
Fugu can jailbreak any iOS version from iOS 12 to iOS 15 on these devices. However, some features may not work on certain versions or devices. For example, Fugu does not support tweaks on iOS 15 yet. You can check the GitHub page of Fugu for more details
and updates (
https://github.com/LinusHenze/Fugu).
Conclusion
Fugu is an innovative jailbreak tool that leverages the checkm8 exploit to jailbreak any iOS device with A5 to A11 chips. It is open source, easy to use, and compatible with most iOS versions. If you want to try Fugu, make sure you follow the
instructions carefully and backup your data before proceeding. Jailbreaking may void your warranty and expose your device to security risks, so do it at your own risk.
