Pangu is a famous hailbreak team, being the one who released the iOS 9.0.2 jailbreak and since then, the hackers have been in a continuous war with Apple. All vulnerabilities have been patched in the next iOS updates and the jailbreak fans hoped that a miracle will happen and this team will release a new jailbreak tool. Recently, a member of the Pangu jailbreak team, who goes by the name of Windknown has posted an article on the official Pangu team, where he explained the security vulnerabilities and fixes in the latest two iOS versions, 9.2 and 9.2.1, so if you want to know more about iOS’ security, it’s worth checking out his report.
First of all, Windknown doesn’t warn the users to not upgrade to iOS 9.2.1. In fact, he said it’s beneficial to do that, because he suggested that Apple’s OS has multiple kernel vulnerabilities which have been reported by the members of the Google Project Zero team. So, there’s a vulnerability that can be prompted in the iOS sandbox, being able to attack the kernel, then to execute the kernel code to obtain permission.
Windknown has posted his technical article in Chinese, but it was translated into English and we figured out what he meant to say. According to him, iOS 9.2.1 contains many security fixes and they prevent execution of malicious code on an iPhone or iPad, but some would start making speculations regarding a possible upcoming iOS 9.2.1 jailbreak. In fact, the report is only a technical write up and the hacker explains what improvements have been made to the iOS 9.2.1 and what the vulnerabilities of its predecessor were. If Pangu would have managed to squeeze out a potential untethered solution for iOS 9.2.1, the announcement would have been made differently, so we must remind you that Windknown has posted only an educational report and nothing more. But he left opened doors for interpretation.
