The hacking team behind the "unc0ver" jailbreaking tool has released a new version of the software that can unlock every single iPhone, including those running the latest iOS 13.5 version.
Calling it the first zero-day jailbreak to be released since iOS 8, unc0ver's lead developer
Pwn20wnd said "every other jailbreak released since iOS 9 used 1day exploits that were either patched in the next beta version or the hardware."
The group did not specify which vulnerability in iOS was exploited to develop the latest version.
The
unc0ver website also highlighted the extensive testing that went behind the scenes to ensure compatibility across a broad range of devices, from iPhone 6S to the new iPhone 11 Pro Max models, spanning versions iOS 11.0 through iOS 13.5, but excluding versions 12.3 to 12.3.2 and 12.4.2 to 12.4.5.
"Utilizing native system sandbox exceptions, security remains intact while enabling access to jailbreak files," according to unc0ver, meaning installing the new jailbreak will likely not compromise
iOS' sandbox protections.
Jailbreaking, analogous to rooting on Google's Android, is a privilege escalation that works by exploiting flaws in iOS to grant users root access and full control over their devices. This allows iOS users to remove software restrictions imposed by Apple, thereby allowing access to additional customization and otherwise prohibited apps.
But it also weakens the device's security, opening the door to all kinds of malware attacks. The added security risks, coupled with Apple's steady hardware and software lockdown, have made it difficult to jailbreak devices deliberately.
Furthermore, jailbreaks tend to be very specific and based on previously disclosed vulnerabilities, and very much dependent on the iPhone model and iOS version, in order for them to be successfully replicated.
