The LiberiOS jailbreak is what's called a KPP-less jailbreak (KPP stands for Kernel Patch Protection). But also because I'm a huge fan of Jonathan Levin's work and his contributions to the community. I'm going to focus on LiberiOS for this post since that's the only jailbreak I've tested. This is especially true for the latest iOS 11 jailbreak, both LiberiOS and Electra jailbreaks, which are based on Ian Beer's async_wake exploit, have very different techniques than the previous jailbreaks and most (all?) of the existing tools are broken on these jailbreaks. Even though there are already many, many blog posts, tutorials and even youtube videos about "reverse engineering iOS apps", every time Apple releases a new iOS version the "game" changes researchers have to find a new way to jailbreak the new released version of iOS and we have to update our tools to work with the new jailbroken environment.
