Hackers who created the “unc0ver” jailbreaking tool for iOS have now released a new version of the software. The new jailbreaking tool with version 6.0.0 can allegedly be used to jailbreak any iOS device running iOS 11.0. Unc0ver 6.0.0 is said to do this through iOS 14.3 using a kernel vulnerability. As the new version is here, the developers boast it to jailbreak almost every iPhone.
According to the unc0ver website, the new tool has been extensively tested across a range of iOS devices. The team behind this tool has reportedly tested it on a range of devices running various software versions. One of the tested devices includes an iPhone 12 Pro Max with iOS 14.3. As per the website, unc0ver 6.0.0 utilizes “native system sandbox exceptions” to maintain security while accessing jailbreak files.
Unc0ver 6.0.0 and iOS Jailbreaking Tools
Before the initial release of unc0ver, there was only one way to jailbreak iOS devices up to the iPhone 8 and iPhone X. It was possible using “checkra1n,” am another jailbreaking tool developed by the same security researcher responsible for the “chevkm8” exploit. So to address these security issues, Apple released iOS and iPadOS 14.4 in January. This new version of the operating system introduced security fixes for kernel and WebKit vulnerabilities that affected devices running previous versions of iOS/iPad OS 14.
Pwn20wnd, one of the developers of unc0ver tool and an iOS hacker, tweeted how the new version exploits a kernel vulnerability. According to the tweet, unc0ver version 6 utilizes an exploit based on a kernel vulnerability patched in iOS 14.4. He said that it offers “optimal exploit speed and stability.” As said before, the new version works on previous iOS 14 versions only. iPhones and iPads that have been updated to iOS / iPad OS 14.4 are not compatible with the new unc0ver 6.0.0. You can’t downgrade to iOS 14.3 either.
So, if you have an iOS device running iOS versions less than 14.4 then you can use unc0ver version 6 to jailbreak your device. If you have updated to iOS 14.4 already then there’s no way you can do anything.
