tfp0 Jailbreak Exploit Achieved On iOS 13 Beta 2 By Luca Todesco
Luca Todesco of Yalu102 and general jailbreak fame has taken to Twitter to show a working tfp0 exploit working on Apple’s recently released iOS 13 beta 2.
The discovery and potentially game-changing discovery came just 24-hours after release of the second pre-release seed of iOS 13.
This isn’t the first jailbreak-based activity that we have witnessed on Apple’s iOS 13 platform. Developer @iBSparkes had previously shown the Cydia package manager running on the initial iOS 13 beta release, which immediately injected hope into an ever-positive community that iOS 13 is definitely going to be able to be liberated and isn’t as security tight as Apple would hope. Now, this announce strengthens that position and suggests that the future of jailbreaking could indeed be bright.
The tweet from Todesco shows enough information to prove the existence of a tfp0-based exploit on the latest release. This exploit would essentially allow anyone with the necessary abilities and skills to read and write to the device’s kernel memory, which is really the total power that a jailbreaker would need over Apple’s system in order to pull together something potentially releasable to the public.
We’ve seen this type of power in previous jailbreaks which have been well received by the community, with particular homage being paid to Ian Beer of Google’s Project Zero team whose tfp0 discovery and work facilitated both iOS 11 and iOS 12-based jailbreaks.
Based on Todesco’s tweet, we know that there is still some work to do to update his offsets to support iOS 13 beta 2 but it is immediately good news that this bug still exists in Apple’s latest release and that the company has yet to patch it. With that said, this could be part of the cat and mouse game between Apple and jailbreakers whereby the company is aware of the bug but is waiting until the last minute to patch it in the hope that jailbreakers continue to work to exploit that weakness and not focus on finding others.
We don’t have any type of proof or confirmation that Todesco or any of his associates would use this discovery to pull together a jailbreak. However, it’s definitely good news knowing what is theoretically possible and that we could have a jailbreak to look forward to in our near future.
