How Are Jailbreaks Found and How Do They Work? iOS Kernel Exploitation Presentation Gives the Technical Details

Sep 14, 2011 - 7 Comments

How Jailbreaks Work

Renowned jailbreaker i0n1c, aka Stefan Esser, has put together a rather extensive presentation titled “iOS Kernel Exploitation” that explains exactly how jailbreaks work, ranging from how the exploits are found, how new code is injected into the iOS devices, how untethers work, and so much more. It was presented live at last months Black Hat security conference, but now the slides are freely available on the web for all to see.

The 97 slide presentation includes the following main topics and dives into very specific details:

  • Introduction
  • Kernel Debugging
  • Kernel Exploitation
    • Stack Buffer Overflows
    • Heap Buffer Overflows
  • Kernel patches from Jailbreaks

This is a fairly technical read with plenty of code samples, making it an extremely interesting look into the world of jailbreaking and iOS security. It’s pretty much a must read for anyone interested in security, development, iOS, Mac OS X, or just jailbreaking in general.

These jailbreakers are a pretty smart group of people, it’s no wonder Apple and Facebook are busy hiring them!
