Many people are not aware that the Fugu15 source code is a golden opportunity for developing iOS jailbreak tools with the Fugu15 Kernel Patchfinder for kernel exploit.

Fugu15 Jailbreak For iOS 15

Great and exciting news for jailbreakers!

‘Fugu15’ on iOS 15.4.1 will be demonstrated by Linus Henze at the Objective by the Sea conference.

Finally, a new jailbreak for iOS 15 – iOS 15.4.1 called Fugu15 Jailbreak has been made available. From this Fugu15 jailbreak, you may learn everything there is to know about this Fugu15 jailbreak, including Fugu15 compatible devices, supported iOS versions, features, and more.

The creator of the most recent jailbreak for iOS 15, Linus Henze aka @LinusHenze from Koblenz, Germany, has begun a new chapter in the history of jailbreaking iOS 15 with the release of Fugu11 Jailbreak. The second jailbreak program based on the checkm8 hack is called Fugu15.

Fugu15 Jailbreak for iOS 15 Step 1

What Is Fugu15 Jailbreak?

Fugu15 Jailbreak is the open-source jailbreak tool based on the checkm8 exploit. A semi-untethered permanent jailbreak for iOS 15 is called Fugu15. It has a kernel exploit, the code-signing bypass, another kernel PAC bypass, as well as a PPL bypass. The Fugu15 jailbreak does not enable tweaks and tweak injection libraries since it is designed for developers. Fugu15 code signature bypass via trustCache injection.

This jailbreak will not be untethered, according to further information. Using Fugu15 to jailbreak your device will allow you to reboot it without losing your jailbreak. That means, after you have jailbroken your device, you do not need to download and use programs like Unc0ver, Taurine, or Chimera. When you’re through, your prison has been breached. You must restore your smartphone if you wish the jailbreak to be removed.

The developer claims that following a successful jailbreak with Fugu15, jailbroken devices will work with Sileo or Cydia. The iDevice must also be connected to the Mac computer for it to be jailbroken using Fugu15.

Fugu15 Jailbreak for iOS 15 Step 2

Fugu15 Safari Jailbreak (WebKit Jailbreak) iOS 15 Jailbreak

With the exception of a Web Server that hosts Fugu15, a computer is not necessary to install the Fugu15 jailbreak via Safari.

Fugu15 Jailbreak Online – Sign Permanently | No Revoke

Fugu15 is a permanent semi-untethered jailbreak, in comparison to other jailbreaks. This eliminates the need for re-signing it every seven days and allows you to install it instantly from Safari, which is a highly unique jailbreak in today’s world.

This is made possible through a flaw discovered by Linus Henze that permits permanent applications on iOS up to about 15.5 Beta 2.

This implies that for the typical jailbreak user, signing it doesn’t have to be done on a computer all the time, and installing Fugu15 jailbreak doesn’t even require a PC. A great innovation that allows you to sign permanently without revoking is the Fugu15 jailbreak online method.

Fugu15 Jailbreak Kernel PatchFinder

Linus Henze has shared some exciting news about the Fugu15 jailbreak for iOS 15.0 to iOS 15.5 Beta 1 / Beta 2 or such. The Fugu15 jailbreak would be supported with PAC devices (A12+ and higher), and it was shown at the Objective By The Sea security conference.

Software called The Fugu15 Kernel Patchfinder is used during jailbreaking to locate the items we need to fix. These might include different kinds of checks, procedural elements, offsets, credentials, and so on. So each time your phone wakes up, the system components and data will be randomly located since iOS kernels use KASLR Kernel Space Layout Randomization.

They may be located in memory and patched in a way that facilitates a jailbreak using the Fugu15 Kernel Patchfinder. Increased root privileges, sandbox escape, reattaching file systems, and other features are all possible with the Fugu15 Kernel Patchfinder.

Linus Henze has made available on GitHub the Kernel Patchfinder for the Fugu15 jailbreak. The patchfinder is a critical component of Fugu15 since it helps us to discover and install the kernel patches necessary for the jailbreak. It appears like Fugu15 will be launched soon.

Fugu15 Rootful Jailbreak For iOS 15 – iOS 15.4.1

Linus Henze, the ingenious security researcher behind the original Fugu15 rootless developer jailbreak that paved the way for the Dopamine jailbreak on iOS and iPadOS 15.0-15.4.1, has unveiled the rootful edition of Fugu15. This development redefines the iOS jailbreaking scene.

Fugu15’s developer edition was a pivotal demonstration of the possibility of retaining root privileges all along. Current iOS and iPadOS 15 jailbreaks have transitioned to rootless environments, each with its own set of advantages and disadvantages.

Similar to the original Fugu15, the Fugu15 Rootful Edition is a semi-untethered perma-signed jailbreak, exclusive to developers, targeting iOS 15.0-15.4.1. This iteration offers complete support for jailbreak tweaks and operates with root privileges right from the start.

Lars Fröder, the lead developer behind the Dopamine jailbreak, hinted at the possibility of integrating some of Fugu15 Rootful Edition’s techniques into Dopamine for the community’s benefit. For instance, Fugu15 Rootless Edition shows promise in running arm64 jailbreak tweaks on arm64e devices.

The iOS and iPadOS 17 jailbreak may harbor CoreTrust bugs similar to the one exploited by TrollStore, alongside a PPL bypass that could potentially usher in an iOS and iPadOS 16 jailbreak alongside the kfd exploit.

Fugu15 – Rootful Edition Tested Devices And iOS Versions

✅ iPhone Xs Max: iOS 15.4.1

✅ iPhone 13 Pro: iOS 15.1

Fugu15 Jailbreak Safari-based Installation – No Computer

Fugu15 Jailbreak for iOS 15 iPA

Fugu15 Jailbreak Installing Via TrollStore

On iOS 15-compatible devices, the TIPA package Fugu15 can only be installed with TrollStore. That iOS 15 jailbreak tool was created for TrollStore 1.3.4 or higher; it cannot be installed with standard sideloading apps.

Step 1 > Install TrollStore on any version of iOS 15 or iOS 15.4.1 firmware.

Step 2 > Save Fugu15.tipa to iCloud after downloading it.

Step 3 > Also with the TrollStore app, transfer the downloaded Fugu15 IPA file.

Step 4 > When TrollStore is loaded, the Fugu15 Jailbreak application will immediately be installed.

Step 5 > Excellent! Go to the Home Screen and open the Fugu15 app.

How To Install Sileo On Fugu15 Without PC

Installing Sileo package manager with Fugu15 jailbreak is recommended as soon as you are jailbreak. Use of a PC is not required. Your device itself can be used to do the Sileo installation. Fugu15 comes with iDownload, same like all other Fugu jailbreaks. Port 1337 is the gateway to the iDownload shell. You may use it to download and install Procursus Bootstrap and Sileo iOS 15 on your iDevice easily.

Step 1 > To begin the jailbreak, install Fugu15 for iOS 15 via TrollStore.

Step 2 > Get iSH Shell by browsing the App Store.

Step 3 > Launch the iSH Shell application to run specific instructions.

Step 4 > To connect with iDownload, type the command “nc 127.1 1337.”

Step 5 > To install Sileo and Procursus Bootstrap, type the “bootstrap” command.Step 6 > After that, enter “uicache -r” into Respring to make Sileo appear just on your home screen.

How To Install Sileo On Fugu15

Fugu15 Demonstration

In the Fugu15 jailbreak demo, Henze uses the stock Safari web browser on an iPhone to go to and clicks a hotlink to start the installation of the Fugu15 app on the Home Screen.

The installation of the Fugu15 app is confirmed by Henze through an iOS pop-up request, and it then downloads to the Home Screen similarly to how a Software Store-purchased app would. When finished, the Fugu15 icon for the app looks like that of the Apple Developer app instead of the Fugu15 application on iOS 15.4 jailbreak download.

Henze notes that the Apple Developer app being there on the Home Screen is due to the fact that he needs a properly signed application in order to install Fugu15 Jailbreak on the device. When Henze runs the recently downloaded Apple Developer application, Fugu15 Jailbreak may then be quickly injected into the program. Henze now deleted the Developer app, which he did after a short wait in which the program asked him to do so, leaving the Fugu15 jailbreak app in its place.

Henze joyfully taps on the lone Jailbreak button that is visible on the Fugu15 app. Henze begins the jailbreak procedure, changes to the Log to show what just happened, and then uses Terminal on the Mac to install on Procursus bootstrap.

Fugu15 Jailbreak Package Manager 

Sileo is the default package manager of Fugu15.

Sileo helps to explain that since the Fugu15 jailbreak is rootless and jailbreak tweaks haven’t been updated for compatibility yet, there aren’t any to install as of right now. Lead Odyssey Team creator CoolStar, who hasn’t yet publicly published Cheyote because of the same reason, supports this jailbreak tweak.

Fugu15 Procursus Bootstrap With Sileo

Sileo and the procursus bootstrap are both included with Fugu15. To install both, use iDownload’s bootstrap command. After that, you might need to respring in order to have Sileo appear just on Home Screen (uicache -r).

A symlink from the location /var/jb to where Procursus is installed is located in /private/preboot/jb.

Procursus On Fugu15 Jailbreak For iOS 15

In fact, the Fugu15 jailbreak uses the same Procursus bootstrap as the Odyssey Team’s Odyssey, Taurine, and forthcoming Cheyote jailbreaks, therefore the device will instead be loaded using the Sileo package manager rather than Cydia.

The Most Latest TrollStore Supports For Linus Henze’s Fugu15 Jailbreak

To facilitate  Fugu15 install on arm64e devices running iOS 14.0 up to 15.4b4, the TrollStore IPA installer for iOS 15 with Fugu15 currently employs this app injection technique. Now, Safari may install TrollStore on A12-A15 devices without the usage of command-line tools.

The Installer currently only supports up to 15.1.1 because it uses multicast bytecopy, even though TrollStore should function up to 15.4.1. Installing TrollStore up to version 15.4.1 should be doable once the Fugu15 install method is made available to the general public.

Fugu15 With CoreTrust Bug 

In order to sign the Fugu15 jailbreak software and get around Apple Mobile File Integrity, Henze’s Fugu15 jailbreak effort depends on a latest CoreTrust bug (AMFI). Additionally, it appears to use a weakness that allows writing to PPL memory and a bypass of the Page Protection Layer (PPL) and Pointer Authentication Code (PAC).

📌 It’s still not possible to use Fugu15 to install jailbreak tweaks! But don’t worry, iPA Store is the best available solution for that.

🔹 Fugu15 jailbreak is Semi-untethere jailbreak for iOS 15.

🔹 Fugu15 has not been given an official ETA but is most likely coming soon.

🔹 Fugu15 does not currently have a tweak injection library because it lacks root access, and Fugu 15 Tweaks do not function at this time. However, Fugu15 will soon receive updates and support.

🔹 Developer recommended waiting till this is released and in a workable state for the end consumers if you’re hoping to upgrade your Fugu 15 jailbreak via a future restore to a compatible iOS version.

Tweaks For iOS 15

To get tweak injection to function on iOS 15, there are several different techniques. In particular, with a tethered jailbreak. We can’t use semi-tethered or semi-untethered jailbreaks right now because we don’t have a reliable rootless tweak injector yet.

CoreTrust Certificate Validation Vulnerability (CVE-2022-26766) 

✅ Code Signing On iOS

» All executables on iOS must have a valid code signature.

  • Enforced in the kernel by Apple Mobile File Integrity (AMEI) 

» Two types of code signatures

Ad-Hoc – Self-Signed (Pre Installed binaries, signature hash in TrustCache) 

CMS – Signed using a certificate.

» Code signatures can contain entitlements (a list of additional permissions) 

» AMFI delegates CMS validation to CT ( Via CTEvaluate AMFI CodeSignatureCMS )

» CT ensures CMS blob is valid and the hash inside. It matches the code signature hash. 

» Returns flags to AMFI to indicate certificate type (e.g. developer cert, AppStore cart, …) 

» CT returns success even if the signer is not trusted (not a vulnerability) 

✅ Apple Mobile File Integrity 

» Rejects code signature if CT validation fails.

» If it succeeds, check CT flags.

» Flags indicate binary was signed by an AppStore certificate > Accept code signature.

» Otherwise, amfid will be asked to validate the signature. 

✅ Vulnerability 

» CT flags are taken directly from the certificate.

If certain OIDs are present in the certificate, flags will be set.

» Include AppStore OID in certificate.

  • CT will return “signed using AppStore certificate” in the CT flags.
  • AMFI performs no further validation when signed using an AppStore certificate.
  • Remember: CT does not verify the cert issuer.

✅ Apple’s fix 

» CT now only returns flags if the certificate was issued by Apple. 

CT still returns success even if the issuer is untrusted but flags will remain 0 (macOS compatibility) 

» This vulnerability was a regression, iOS 13 and below are not affected.
