Linus Henze to demonstrate Fugu15 jailbreak for iOS 15.4.1 at Objective by the Sea this October

There has been a lot of doom and gloom in the jailbreak community lately given the issues surrounding iOS and iPadOS 15 jailbreak. In fact, even Odyssey lead developer Team CoolStar has been publicly discussing how iOS and iPadOS 15.1.1 are likely to be the last. firmware they are developing a jailbreak for because of how much harder Apple makes things.

But for security researcher Linus Henze, author of the Fugu14 decoupling currently being used to break the unc0ver prison, despite the difficulties, there is still a bright light at the end of the tunnel.

It looks like Henze will be giving a 50-minute presentation at the Objective by the Sea Mac security conference this October titled “Journey to iOS 15.4.1 Jailbreak”, which will focus on what “Fugu15″is coming up with. Henze says that he will not only show you how to hack iOS and iPadOS 15.4.1, but also share a demo of his Fugu15 jailbreak.

Here is an excerpt from Henze from the Objective by the Sea event webpage:

With the introduction of new protections in iOS 15 (and especially 15.2), it has become much more difficult to create a jailbreak. Previously, a kernel vulnerability was enough for a jailbreak, but now a PAC or PPL bypass is also required. Some people even said that iOS 15.1.1 will be the last version to get a public jailbreak ?

In my report, I will show how you can jailbreak iOS 15. 4.1 even with all the latest security measures. I will describe the vulnerabilities exploited in the Fugu15 chain and how some of the mitigations introduced in iOS 15.2 can be bypassed. A demo of Fugu15 will also be shown, including an interesting (and unusual) way to install Fugu15 on a device.

If it wasn’t already obvious from Henze’s words, it looks like he’s already developed a jailbreak for iOS 15.4.1 called Fugu15 and plans to share some of the methods he used to bypass Apple’s latest security mechanisms – the same ones that seem to drain motivation today’s jailbreak developers.

Sharing these techniques can generate more inspiration.

The mocking wink at the end of the first paragraph also leaves a lot of wiggle room as to whether iOS 15.1.1 will be the last iOS to get a public jailbreak or not, but we won’t know more about that until much later.

There is still a lot of time between now and October, and in fact iOS and iPadOS 16 will launch before then, which will likely encourage many users to switch to new features.

Having said all that, even the slightest possibility that we might see a jailbreak supporting the latest iOS and iPadOS 15 means that anyone hoping for a jailbreak should continue to stay on the lowest possible firmware just in case something will fall.

While no one but Henze has any idea what might materialize as a result of the security researcher’s hard work at the moment, subtle verbiage certainly gives many of us hope that the jailbreak is not dead and will indeed continue to exist.
