What is Osiris?
Osiris is proof-of-concept jailbreak for iOS 11.2-11.3.1 firmware. It is developed by security researcher GeoSn0w for learning and development purposes.
Auxilium Development Team members, M4cs and MidnightChips, are also a part of this project and are currently involved in testing.
Here’s a video demonstration of this jailbreak tool.

Here’s a quick rundown of what’s working and what’s not –
- Osiris triggers the exploit properly and achieves tfp0 (root access) on iOS 11.
- Apart from root access, Sandbox escape and AMFI codesign patch are also functional.
- System updates (OTA updates) become non-functional once you install this tool.
- Remounts the root filesystem as R/W on iOS 11.2.6 and below versions. Once Jonathan Levin updates QiLin toolkit, it will achieve R/W access on iOS 11-11.3.1 as well.
- Cydia and Substrate are not a part of this tool. Moreover, the developer isn’t too keen on implementing these components in future versions.

Update (June 15) – Version Alpha 2 released. It replaces Ian Beer’s multi_path exploit with the VFS exploit. You no longer need to have a paid developer account in order to install and run this tool.
As of right now, this jailbreak is aimed at developers and the general public should stay away from it.
If you are interested in testing it out, rev up your Mac and get a test device ready.
- Compile the XCode project given above on your Mac using a developer account. Since the tool uses the multi_patch exploit, you must have access to a paid developer account or a signing service.
- Run the jailbreak tool on your iPhone/iPad.
- Alternatively, you can download and sideload the IPA file if someone compiles it and makes it public.
Admittedly, the entire premise of this open source project is to kickstart the jailbreak development process by utilizing existing exploits.
If you just want Cydia, you should probably stay away from any tool that goes public before Coolstar’s Electra jailbreak.
