When it released iOS 7.1, Apple thanked the hackers that had jailbroken iOS 7.0, therefore allowing it to patch several security exploits. Since then, no iOS 7.1 version has been successfully jailbroken – at least on 2013 devices. However, it looks like an untethered iOS 7.1.1 jailbreak is possible, with two independent sources confirming it.
Well-known security researcher @i0n1c posted a photo on Twitter showing an iPhone 5c running iOS 7.1.1 that was successfully jailbroken. The image clearly shows that Cydia is installed on the handset, that that is obviously only possible after a successful jailbreak.
“That iOS 7.1.1 jailbreak is not based on a long vulnerability chain,” he wrote. “It uses a single beautiful kernel bug that goes from mobile to kernel.”
Considering that the iPhone 5c running iOS 7.1.1 has been jailbroken, that means other iOS devices released last year that were updated to Apple’s latest OS version can also be jailbroken in a similar manner. However, that doesn’t mean a public tool to jailbreak iOS 7.1.1 will be released anytime soon, as hackers may be more interested in keeping the vulnerability private until iOS 8 rolls out, so Apple can’t quickly patch it up with a following update.
A different hacker, known as Winocm, also obtained an iOS 7.1.1 untethered jailbreak, but on an iPhone 4, an older device which should still be jailbreakable.
An image and video showing the iOS 7.1.1 Jailbreak on iPhone 5c and iPhone 4, respectively, follows below.
