Hackers from GTISC Jailbreak iPhone 5s on iOS 7.1.1, Following Jailbreaks from Winocm and i0ni1c

Security researchers at Georgia Tech Information Security Center (GTISC), Yeongjin Jang and Tielei Wang, have just revealed that they have successfully jailbroken iPhone 5s running iOS 7.1.1.

Jang, a graduate at Gatech has posted a YouTube video detailing his accomplishment with the iOS 7.1.1 jailbreak running on iPhone 5s.

The 4-minute long video by Jang demonstrates how he could install an app remotely and get the unsigned app to work on the jailbroken iPhone 5s running iOS 7.1.1, as reported by iPhone Hacks.

Furthermore, the jailbreak seems to be tethered as the tipster reveals that one has to run a recovery app after every reboot to run an unsigned app.

Jang reveals a three-step jailbreaking process in his recent Twitter message:

"This is what I did on iPhone 5s, with iOS 7.1.1. The work includes followings. 1. Bypassing sandbox, 2. Getting root permission, and 3. bypassing codesign."

Check out Jang's YouTube video detailing his creation below:

Meanwhile two discerning members of the jailbreak community, @osxreverser and @i0n1c, have confirmed that the new jailbreak by Jang appears to be legit or real.

Here is what the two veteran jailbreakers had to say about Jang's creation:

@osxreverser: Three known private jailbreaks for 7.1.1. The "community" must be really pissed off ahahhahah this is beautiful to watch :)
@Taiki__San: @osxreverser three?
@osxreverser: @Taiki__San stefan, winocm and the chinese guy in the us

@i0n1c: I welcome @blue9057 to a world of pain

Though the new jailbreak by Jang appears to be legit, it is still unclear if he used the same method employed by winocm and i0n1c to jailbreak iOS 7.1.1 successfully.

Neither winocm nor i0n1c has made any claim of releasing the iOS 7.1.1 jailbreak to the public, as Apple's iOS 8 release is expected at the Worldwide Developer Conference (WWDC) in June and the evad3rs have already hinted at preserving their existing jailbreak exploits until the next major iOS release.

Meanwhile, Jang has also remained silent about a probable jailbreak release for iOS 7.1.1. However, three consecutive jailbreak demonstrations for iOS 7.1.1 in a few days' time have further strengthened the prospects of an impending public release of iOS 7.1/7.1.1 jailbreak.
