iOS hacker Pwn20wnd was played an instrumental role in various iOS 11-centric projects in recent memory, including the Electra and unc0ver jailbreak tools and the Rollectra un-jailbreaking tool. As of this weekend, however, we can add the Osiris jailbreak tool to that list.
Pwn20wnd released a rewrite of the Osiris jailbreak tool for iOS 11.0-11.4 beta 3 Sunday afternoon. Osiris uses Ian Beer’s tried and true iOS 11 exploits to achieve a jailbreak on the aforementioned firmware versions, but unlike other jailbreak tools available already, it doesn’t install Cydia.
