A hacker claims to have a new iboot exploit to have found use on all Apple hardware with an A5 or A5X processor. The exploit can also be used on A6 and A7 processors to Apple.
According to the hacker is the iboot-exploit with a software update by Apple to be sealed, and means in practice that all the Apple hardware with an A5 or A5X-soc always will be to crack. Also it is a so-called untethered exploit which also after a restart of the phone or smartphone continues to be available. Nevertheless, says iH8sn0w his new method not to publish. Not only would the exploit be complex to implement, want the hacker for the method to keep that a secret also in the future search for new vulnerabilities to iOS to can crack.
It is unclear yet whether the exploit on A6 and A7 socs is applicable. IH8sn0w says this would like to investigate. Incidentally, there is by the Evad3rs team in december a jailbreak released for iOS 7.
