In an interview to Softpedia in Amsterdam for the Hack in the Box conference 2012, The Chronic Dev Team confirmed that they have already found the exploits necessary to jailbreak iOS 6. This sounds weird, since the beta builds of iOS 6.0 haven’t been announced yet. iOS kernel hacker pod2g said:
“We won’t give up on jailbreaking iOS devices because this is too important for us and we already have a part of the jailbreak for iOS 6 and we will be ready right on time for it,” Cyril said.
When asked about the nature of possible jailbreak and exploits of upcoming iOS 6.0 (userland or Bootrom), Cyril (aka pod2g) denied to share the detail in length to avoid possible patch by Apple. He only said that the exploits they have discovered will allow them to inject code into new devices (hinting iPod touch 5G, iPhone 5) to dump memory which will eventually assist them in locating vulnerability.
“We will not give you the exact recipe, but we have other exploits that we won’t release at any time. This is our secret. It allows us to inject stuff into new devices and to start dumping the memory. When we have the dumps, we look at different ways of finding the vulnerability,” he explained.
According to the Chronic Dev Team, they achieve the jailbreak by reverse engineering the kernel topped with some fuzzing. Cyril explains that the team works synergistically and that each member is assigned with certain task to find vulnerabilities. On an average the team discovers them in one month or two and then exploits them. The process is started only when the public version of the firmware is released. And this is the primary reason for the delay in jailbreak
“That’s why we always have a delay after the release to do a jailbreak. Because we need to be assured that what we do will work for sure, that they don’t fix it in the beta 3 or beta 4, so we start only when the release is here.”
