Apple claims the hack was being widely used as late as January, but it was patched with iOS 14.4.
Jailbreaking iPhones has become a game between hackers and Apple. Currently, as soon as a party launches an exploit, Cupertino developers patch a hole in it. Apple has already fixed the flaw of the new version of Unc0ver. However, for those willing to risk not upgrading their handset, they’re going to jailbreak everything from the iPhone 5s to the iPhone 12.
A community of hackers unveiled the new update of their jailbreaking programme that can crack nearly any of the iPhones currently in operation. Unc0ver fits for iOS 11 (iPhone 5s) through iOS 14.3. However, it doesn’t work with the new version of iOS (14.4) because it relies on a flaw that Apple fixed in January.

According to Apple’s patch notes, CVE-2021-1782 was a kernel flaw that could theoretically allow malicious software to increase privileges. The jailbreaking community Unc0ver Team states that it uses the security hole to enter the iOS kernel and circumvent those restrictions. It says that Unc0ver v6.0.0 will selectively disable Apple’s security mechanisms without rendering the iPhone vulnerable.
“Unc0ver preserves security layers designed to protect your personal information and your iOS device by adjusting them as necessary instead of removing them,” the group says on its website. “With this security adjusted on your iOS device, you can run your favorite jailbreak apps and tweaks while still being protected from attackers.”
Despite the programme going around previous fixes and holding them in place for increased stability, it’s worth mentioning that it uses the crucial flaw that Apple says hackers have already used in the wild. Using Unc0ver at your own risk. The easiest way to keep your iPhone safe is to keep it up-to-date, but this typically involves blocking the new jailbreaking software.
