A team of cyber-security researchers and hackers have released a new jailbreak package dubbed Unc0ver (from the name of the team that devised it) that works on all recent iOS versions.
Jailbreaking an iOS mobile device it is possible to remove hardware restrictions implemented by the Apple’s operating system, Jailbreaking gives users root access to the iOS file system and manager, this allows them to download and install applications and themes from third-party stores.
By default, Apple does not allow users to have full control over their iPhones and other iOS devices, citing security reasons.
The Unc0ver team today released Unc0ver 5.0.0, the latest version of their jailbreak, which can root and unlock all iOS devices, even those running the latest iOS v13.5.
The jailbreak exploits a zero-day vulnerability in the iOS operating system that was discovered by Pwn20wnd, a member of the Unc0ver team, and that has yet to be addressed by Apple.
Pwn20wnd states that #unc0ver v5.0.0 will be a big milestone for jailbreaking because it is the first zero-day jailbreak released since iOS 8 that was released in September 2014.
Other jailbreak applications released since iOS 9 used 1-day exploits and and did not work on the current iOS version.
#unc0ver v5.0.0 will be the first 0day jailbreak released since iOS 8!

Every other jailbreak released since iOS 9 used 1day exploits that were either patched in the next beta version or the hardware.
This will be a big milestone for jailbreaking.
The new Unc0ver 5.0.0 jailbreak can be used from iOS, macOS, Linux, and Windows devices.
The Unc0ver team published instructions on their website.
“unc0ver is designed to be stable and enable freedom from the moment you jailbreak your device. Built-in runtime policy softener allows running code without Apple’s notarization and pervasive restrictions.” reads the website.
“unc0ver Team strongly cautions against installing any iOS software update that breaks unc0ver as you can’t re-jailbreak on versions of iOS that are not supported by unc0ver at that time.”
The Unc0ver team tested the jailbreak on iOS 11 through iOS 13.5, the software did not work on iOS versions 12.3 to 12.3.2 and 12.4.2 to 12.4.5.
What makes this jailbreak outstanding is that according to Pwn20wnd it doesn’t impact Apple’s iOS security features.
Let’s see when Apple will release security updates to address the zero-day vulnerability exploited by the Unc0ver team.
