A chinese jailbreak tool called PanGu

PanGu, an Apple Inc. (NASDAQ:AAPL) iOS 7.1.1 jailbreak was released on Monday, enabling users to do more with their iPhone 5S, iPad Air and other iOS devices.

Commotion and curiosity about the PanGu jailbreak, a tool used to remove software limitations on iOS, rose out of the iOS jailbreak community early on Monday before the release of the previously rumored PanGu jailbreak. While proof of the existence of a working iOS 7.1.1 jailbreak has made the rounds around Twitter and the Reddit /r/Jailbreak community, no jailbreak tools have been publicly released, until now.

Prior to the release of PanGu, most iOS jailbreak users welcomed the release of an iOS 7.1.1 jailbreak tool. But one developer has voiced opposition toward the jailbreak.

Stefan Esser, better known to the jailbreak community as i0n1c, sent out two tweets criticizing the release of PanGu on Monday. In the tweets, Esser took particular issue toward the PanGu jailbreak developer team, suggesting that iOS security bugs he disclosed to the team during an iOS security training session were used to develop the jailbreak.

The PanGu jailbreak developer team confirmed i0n1c’s suspicions in the credit section of the PanGu iOS 7.1.1 jailbreak app page.

“Thanks for infoleak bug from @ i0n1c training,” the description reads.

In previous months leading up to the release of PanGu, Esser teased the existence of an exploit that could be used to create an iOS 7.1.1 jailbreak but refused to publicly release a jailbreak tool.

Upon the release of the PanGu jailbreak for iOS 7.1.1, many were quick to download the application. But some have chosen to wait patiently at the sidelines to see if the tool actually works, or instead installs malicious malware applications.
