iOS 11.4.1 / iOS 11.4 Jailbreak News
iOS 11.4 jailbreak and iOS 11.4.1 jailbreak has been achieved by Electra jailbreak using the exploits released by Ian Beer. It was a long journey to achieve the root access for iOS 11.4 and iOS 11.4.1 but you can see the effort jailbreak community put in to this.
Ian Beer Released iOS 11.4.1 Jailbreak Exploits
Ian Beer promised to release exploits for iOS 11.4.1 and he kept the promise by revealing the exploits to the public. In a recent tweet he has linked the Google Project Zero blog post related to the iOS 11.4.1 jailbreak exploits.
A blog post about turning back the clock to 2014, and thinking about what 2022 might be like: https://t.co/R1AsQsZpIL— Ian Beer (@i41nbeer) October 18, 2018
As we know, Electra jailbreak and Unc0ver jailbreak both supports up to iOS 11.4 beta 3 and based on Ian Beer's exploits. Therefore, we can assume that Electra team with CoolStar and Unc0ver team with Pwn20wnd will be in a contest to prove who is the most capable jailbreak team. With that contest, jailbreak community will get a most stable and reliable jailbreak for certain.
Houdini for iOS 11.4 Jailbreak
Abraham Masri published a video of Houdini beta 3 working on iOS 11.4 dev beta. In this demo, he was presenting the Houdini semi jailbreak with some functionalities such as passcode screen customization, icon rename, blank icons and customizable widgets. This is a beta version of Houdini. But, as Abraham Masri is a respectable figure in jailbreak community, it's certain that we will be able to see Houdini in action with iOS 11.4 and lower versions.
iOS 11.4 Jailbreak Achieved by Richard Zhu
Security Researcher Richard Zhu recently tweeted with a video showing Cydia on iOS 11.4 running iPhone 7. However this is most likely a private jailbreak and it will not make to the public at this stage.
The good news is, with this jailbreak it's certain that there are some vulnerabilities available in iOS 11.4 and it will reach to the public in the near future. Also, we believe that Richard Zhu was experimenting on iOS 11.3 or iOS 11.3.1 jailbreak and the same vulnerabilities still present in the iOS 11.4 as well.
iOS 11.4 Jailbreak Demo by 360Vulcan Team
360Vulcan security research team successfully demonstrated iOS 11.4 jailbreak at MOSEC security conference last week. This jailbreak was said to be achieved using Safari and kernel bug. In MOSEC, they have successfully demonstrated iOS 12 jailbreak too.
They will not release an iOS 11.4 jailbreak tool for sure. But knowing that iOS 11.4 is jailbreakable is a reason to enjoy if you are stuck on iOS 11.4 as the iOS 11.3.1 downgrade window is closed.
iOS 11.4 Jailbreak PoC by Brandon Azad
In a recent tweet, Brandon Azad said that he is about to present how to exploit the CVE-2018-4280 bug (libxpc bug) that Apple fixed in the iOS 11.4.1 and he will show it at the beVX Conference which is scheduled for next month in Hong Kong. His presentation is titled Crashing to root: How to escape the iOS sandbox using abort(). He is aimed for iOS 11.2.6 vulnerabilities for the conference, but with the bug details, it could lead to an iOS 11.4 jailbreak.
I'll be presenting "Crashing to root: How to escape the iOS sandbox using abort()" at @bevxcon this September. I'll show how to exploit CVE-2018-4280, fixed in iOS 11.4.1, by crashing maliciously in order to elevate privileges, defeat codesigning, and spawn a shell on iOS 11.2.6. pic.twitter.com/tRxLqD55fY— Brandon Azad (@_bazad) July 30, 2018
It's too early to comment on the iOS 11.4 jailbreak possibility with this, but someone could pick and continue the work where Azad left off.
Min Zheng at DEFCON Hints Possible iOS 11.4 Jailbreak
Min Zheng, a security expert at Alibaba presented two bugs which could possibly lead us to an iOS 11.4 jailbreak. He presented this at the DEFCON conference in Las Vegas and the title of the presentation was Fasten your seatbelts: We are escaping iOS 11 sandbox. You can find his presentation on GitHub.
However, these bugs has been fixed in iOS 11.4.1 update and therefore if someone build a jailbreak with these bugs, it would be for iOS 11.4 and lower versions. Min Zheng will not release a public iOS 11.4 jailbreak tool, but a interested group or a hacker could develop a jailbreak tool for iOS 11.4 with this vulnerabilities.
Ian Beer will Release iOS 11.4.1 Exploits
Ian Beer stated in a recent tweet that he will release iOS 11.4.1 exploits soon. As we know, Ian Beer contributed to the latest jailbreak tools such as Electra jailbreak by revealing exploits he found in his research.
And if you're using the mptcp/vfs exploits for security research (eg with Electra 11.3.1) you should just keep using that. I'll release the 11.4.1 exploits I have but the focus will shift to iOS 12 now :)— Ian Beer (@i41nbeer) September 19, 2018
Once he release these exploits, we may able to see which jailbreak teams will accept the challenge of developing a jailbreak tool for iOS 11.4.1 or iOS 11.4 versions. Also, we have to confirm whether this exploits only support for iOS 11.4.1 or will they support iOS 11.4 too.
Will get to you with the latest news as it happens. Keep in touch.
