iOS JAILBREAK UPDATE: NEW iOS 11.1 SAFARI EXPLOIT | SHOULD YOU UPDATE?

iOS JAILBREAK UPDATE: NEW iOS 11.1 SAFARI EXPLOIT | SHOULD YOU UPDATE?


In today's video, we're discussing a 2 new bugs in Safari that have been successfully used to pwn iOS 11.1 by Richard Zhu. He managed to escape Safari's Sandbox and execute arbitrary code, which is DOPE!, especially when we consider the fact that Safari was supposed to be hardened in iOS 10 (including the JIT). Now, Safari exploits have been used in the past in Jailbreaks, and although it might not be enough for a full jailbreak, it is a good starting point (it is way better than a completely flawless system, right?). It is, however, unknown for the moment whether Richard Zhu will be publishing his findings or at least a whitepaper anytime soon. but I will let you know. VERY IMPORTANT: DO NOT update to iOS 11.x if you're running iOS 10.3.x or iOS 10.x. Even if this 2 bugs might give iOS 11 users some hope for a far future jailbreak if released that is, you are still better off on iOS 10.x since there are already published exploits ready to be used (take the example of Saigon which makes use of publicly available exploits). This is just a heads-up to let you know that if you updated to iOS 11.x, it is not the end of the world and iOS 11 is not fail-proof, nor it is mitigating any possible vulnerability, but you are way safer on iOS 10.x for jailbreak currently.
