An iOS hacker has already showcased an untethered jailbreak of iOS 9 with a proof-of-concept video on YouTube, ahead of the update’s release on September 16.

iOS 9 was initially thought as being particularly difficult to jailbreak due to the implementation of a security feature called Rootless.

According to 9to5mac, Rootless is being touted as internally among Apple engineers as a “huge,” kernel-level feature for both OS X and iOS. The new addition is geared to stop malware, improve the safety of extensions and increase the stronghold of security of sensitive and personal data. To facilitate these features, Rootless is rumored to stop even administrative-level users from gaining access to certain protected files on Apple devices.

Sources at the time claimed Rootless will deal a substantial blow to the iOS jailbreak community.

Furthermore, Apple also contended that it has improved the security of the passcode entry and the two-factor authentication system.

“Enhanced security features in iOS 9 keep your devices and Apple ID secure by strengthening the passcode that protects your devices and improving two-factor authentication by building it directly into iOS, making it harder for others to gain unauthorized access to your Apple ID.”

iOS 9 Jailbreak Achieved before Its Release

Popular jailbreak developer Steven De Franco, aka iH8sn0w, has already achieved a jailbreak for the iOS 9, days ahead of its release, reports 9to5mac.

iH8sn0w added that the jailbreak will work on the beta version of the mobile operating system – iOS 9.1 beta, as well asiOS 9 Gold Master (Build 13a340) and iOS 9.1 beta 1 (Build 13B5110e) versions, both of which are available for download from the Apple’s Developer Center.

The hacker also confirmed that his jailbreak exploit won’t be published to the public and that the jailbreak shown in the proof-of-concept video is “dirty and hacky,” but is a “proper jailbreak.”

The news comes less than a fortnight after a notorious malware named ‘KeyRaider’ targeted jailbroken Apple devices specifically, resulting in the world’s largest iCloud hijack ever.

Over 225,000 jailbroken devices,’ details are said to be stolen due to the hijack, according to estimates by security researchers.

The KeyRaider malware stole information including certificates, purchasing receipts and private keys from over 225,000 valid Apple accounts, targeting jailbroken iPhones and iPads.
