- Windows Kernel Exploitation
Trainer Name: Ashfaq Ansari
Title: Windows Kernel Exploitation
Duration: 2 Days
Objective
This training is focused on exploitation of different Windows Kernel Mode vulnerabilities ranging from Pool Overflow to Use after Free. We will cover basics of Windows Kernel Internals and hands-on fuzzing of Windows Kernel Mode drivers. We will dive deep into exploit development of various kernel mode vulnerabilities. We will also look into different vulnerabilities in terms of code and the mitigations applied to fix the respective vulnerabilities.
Upon completion of this training, participants will be able to:
- Learn basics of Windows Internals
- Understand how to fuzz Windows Kernel mode drivers to find vulnerabilities
- Learn the exploit development process in Kernel mode
- Understand how a vulnerability looks like in driver code
- Understand how a vulnerability can be mitigated
