Stefan Esser, conjointly referred to as “I0n1c”, the hacker behind the iOS 4.3.1 untether has created an incredible presentation on the newest iOS jailbreak techniques. Esser created the presentation for Black Hat last month.
Way to “Exploit iOS Kernel”…
The iPhone user land is locked down terribly tightly by kernel level protections. so any refined attack should embody a kernel exploit so as to fully compromise the device. due to this our previous session titled “Targeting the iOS-Kernel” already mentioned the way to reverse the iOS kernel so as to search out kernel security vulnerabilities. Exploitation of iOS kernel vulnerabilities has not been mentioned nevertheless.
This session can introduce the audience to kernel level exploitation of iPhones.
With the assistance of previously disclosed kernel vulnerabilities the exploitation of uninitialized kernel variables, kernel stack buffer overflows, out of certain writes and kernel heap buffer overflows are mentioned.
Furthermore the kernel patches applied by iPhone jailbreaks are mentioned so as to know how sure safety features are deactivated. A tool are released that permits to selectively de-activate a number of these kernel patches for a lot of realistic exploit tests.
