Jailbreak Tool Updated to Unlock iPhones Running iOS 13.5

The unc0ver jailbreaking tool has been updated with support for the latest iOS releases, courtesy of a zero-day vulnerability, the team behind the utility announced.

The unc0ver jailbreaking tool has been updated with support for the latest iOS releases, courtesy of a zero-day vulnerability, the team behind the utility announced.

unc0ver, which supports iOS 11 through iOS 13.5 (with some exceptions), is advertised as the most advanced jailbreak tool out there, providing users with the opportunity to do with their devices more than what the standard operating system allows them to.

Just as other similar tools out there, unc0ver is relying mainly on known vulnerabilities that are usually addressed in the next platform release. Version 5.0.0 of the application, however, exploits an unknown vulnerability to help users unlock “the true power” of their iOS devices.

“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,” Pwn20wnd, the team behind unc0ver, says.

On the website dedicated to the tool, the team says unc0ver focuses on stability and it preserves the security layers on the device, by only adjusting them, instead of removing them entirely.

The latest version of the tool, they explain, enables “unrestricted storage access to jailbreak applications for sandbox backwards compatibility while keeping security intact by leaving the security restrictions enabled for system and user applications.”

Furthermore, they explain that users who jailbreak their iPhone would still be able to apply iOS updates, as all kernel modifications are done in memory, thus ensuring that devices remain operable when platform upgrades are installed.

The team also notes that their tool has been extensively tested on a large number of devices, ranging from iPhone 7 running iOS 11, to iPhone 11 and iPhone 11 Pro Max running iOS 13.5. The tool was released with support for macOS, Windows, and Linux computers.

The price of some iOS exploits has dropped lately, mainly due to an increased focus on hacking Apple’s mobile platform, and exploit acquisition firm Zerodium recently announced that it would not be acquiring certain types of iOS exploits for the next two or three months.
