Stefan Esser, as known as i0n1c on Twitter, has posted a photo of a jailbroken iPhone 5C device running iOS 7.1.1.
This marks another evidence that the hac3kers in the jailbreak community has some vulnerabilities that they can use to jailbreak the latest operating system by Apple which is currently not jailbroken.
Since the release of iOS 7.1, the Cupertino based company has patched the vulnerabilities used by the developers to exploit the mobile software using Evasi0n7. Ever since, the jailbreak lovers are waiting for a public version of the jailbreak for iOS 7.1.1.
Esser posted a photo of his iPhone 5C jailbroken on iOS 7.1.1.
He also posted some other tweets explaining the jailbreak. One of interesting thing he claimed was that his latest work “is not based on a long vulnerability chain. It uses a single beautiful kernel bug that goes from mobile to kernel.”
This is interesting because we have been told earlier that finding single vulnerability to jailbreak has become so hard and nowadays it requires multiple holes to use together to attack.
All versions of Evasi0n tool have been using multiple vulnerabilities chained together in order to jailbreak. That is why Evad3rs team has multiple ha3kers in the team.
If what Esser has said is really true, that must be a sophisticated sort of work done by him or may be he is better at finding the vulnerabilities compared to the rest of the hac3ers.
Esser first became famous in the jailbreak community for finding jailbreak vulnerabilities for iOS 4.3.1.
All that doesn’t mean that he is going to release it to the public. Esser has given no plans of any public release.
Even he wants to release the jailbreak for public, there would be many people out there who would want him to keep the vulnerability until iOS 8 arrives.
