The tool is compatible with iOS 13.5, the latest software released by Apple just a week ago.
However, that's changed after Apple's recent series of high-profile security blunders. However, as quickly as hackers work to create a jailbreak, Apple works fast to patch the flaws back up, so expect the jailbreak to close soon. Operating outside of Apple's security bubble inevitably increases the number of avenues of attack and users also incur risk when downloading apps that have not been vetted by Apple from third-party sources.
As of now, it isn't clear why these updates are being reissued but, as MacRumors notes, it might have something to do with a bug that seems to be affecting apps as of iOS 13.5. "It only enables reading new jailbreak files and parts of the filesystem that contain no user data".
The jailbreak that unlocks the screen of every iPhone has been released!
Unc0ver allows for the installation of software outside Apple's App Store, and elevated superuser privileges across the operating system. Pwn20wnd, as a member of the Unc0ver team, discovered the zero-day vulnerability used in the new jailbreaking tool.
While this raises more concerns for Apple than its actual userbase, TechCrunch also highlighted that exploit broker Zerodium will no longer buy certain iPhone vulnerabilities because "there were too many of them".
Unc0ver also mentioned that this jailbreak mechanism doesn't affect the core security model of iOS.
The group did not specify which vulnerability in iOS was exploited to develop the latest version.
Dozens of Twitter complaints suggest the issue is affecting people running both iOS 13.4.1 and iOS 13.5, and it's not clear what's causing the problem as not everyone appears to be affected.
What's even more mysterious is that in many cases these updates are days or weeks old, and are the exact same versions of the apps that users previously installed. However, the entire community has yet to fully inspect and assess the jailbreak tool or the team's claims about the security protections as it isn't open-source, making it hard to analyze.
