Fugu15 Semi-Tethered Developer Jailbreak Released [Download]

Fugu15, a semi-tethered jailbreak of iOS 15 for developers, has been released. Created by security researcher Linus Henze, Fugu15 is now available to download on GitHub.

Fugu15 is a semi-untethered permasigned jailbreak for iOS 15. It contains a code-signing bypass, kernel exploit, kernel PAC bypass and PPL bypass. Additionally, it can be installed via Safari, i.e. a computer is not required, except for a Web Server that hosts Fugu15.

The Fugu15 jailbreak is intended for developers and does not support tweaks (no tweak injection library). Multiple devices have been tested working on iOS 15.4.1.

● iPhone Xs Max: iOS 15.4.1
● iPhone 11 (SRD): iOS 15.4.1
● iPhone 12 (SRD): iOS 15.4.1
