i0n1c’s iOS Kernel Exploitation Presentation

The jailbreak community is pretty exclusive, overall they are quite productive and diligent with regular jailbreak updates and releases. Consistently bringing iOS hackers new tweaks through Cydia to keep us wanting to hack our iPhone/iPad. i0n1c will likely be behind the iOS 5 Jailbreak for the iPad and iPhone. I am certain that the jailbreak team is working hard A5 based kernel for the iPad and likely the next iPhone.

i0n1c is definitely one of the more notable hackers, and today he released his amazing presentation on iOS Kernel Exploitation.

This presentation was given by i0n1c at the Blackhat Security Conference last month, it is 97-pages long and consists of a lot of highly technical details. i0n1c talks about stack ahd heap buffer overflows and that are used to exploit the kernel which acts as a bridge between software and the hardware.

Here is the i0n1c’s iOS Kernel Exploitation Presentation

Excerpt: The iPhone user land is locked down very tightly by kernel level protections. Therefore any sophisticated attack has to include a kernel exploit in order to completely compromise the device. Because of this our previous session titled “Targeting the iOS Kernel” already discussed how to reverse the iOS kernel in order to find kernel security vulnerabilities. Exploitation of iOS kernel vulnerabilities has not been discussed yet.

This session will introduce the audience to kernel level exploitation of iPhones.
