Talk Detail

Session 1: Another one bites the apple! (40 mins) by ramses (JunHo Jang from graylab)

OSX/iOS kernel has some attack surfaces from user space such as IOKit, system call, MIG(Mach Interface Generator) handler. Especially, MIG is XNU kernel's distinct feature from LINUX or UNIX.

In this talk, I will introduce some methods related to finding vulnerabilities in XNU kernel's MIG handler, including:

- Analyzing the MIG handler in XNU kernel

- Making a simple fuzzing framework through XNU kernel compile

- Analyzing a kernel heap buffer overflow vulnerability (0-day)

Lastly, I will talk about challenges in exploiting this vulnerablity.
