COURSE SYLLABUS


Module 0

Course introduction


Module 1

Linux exploitation

This module reviews essentials of Linux stack overflow vulnerabilities and the required debugging tools. Everything will be covered in practical scenarios, through finding stack overflow vulnerabilities, binary exploitation, and executing shellcode. 

  • Linux Internals
  • BoF in Linux
  • Heap overflow
  • ELF
  • PLT
  • GOT 
  • SGID
  • SUID
  • Abusing EIP

Module exercises: 

In this section, you will go through some questions and practices related to Linux components and buffer overflow.


Module 2

Bypassing defense mechanisms in Linux systems 

This module will cover common Linux exploit mitigation mechanisms against stack overflow, as well as the techniques to bypass them. Specifically, ASLR, NX, Stack Cookie, RELRO and other exploit mitigations are covered alongside techniques to bypass them.

  • ASLR
  • Stack Cookie
  • RELRO
  • No execute
  • Bypassing techniques

Module exercises: 

At the end of this section, you will discover and exploit a stack overflow vulnerability by abusing NX. 

The purpose of this exercise is to learn ret2libc technique.


Module 3

World of shellcoding 

First of all, we will cover Return Oriented Programming (ROP) fundamentals and all the ways to abuse it. The purpose of this section is to write our malformed ROP chains. After that we will deep dive to all procedures of writing a shellcode for Linux (x86 and x64).

  • ROP basics
  • ROP big picture
  • Exploiting ROP
  • X86 basics
  • TCP shellcode
  • X64 shellcode

Module exercises: 

In this section, you will be writing a Linux-base shellcode. After that you must execute and take advantage of the vulnerability on Linux machines.


Module 4

Linux format string exploitation 

The final section will focus on more complicated techniques, which enable the students to perform exploitation on a secure Linux environment.

  • What is format string?
  • Format string security flaws
  • Exploiting format string 

Module exercises: 

  • Discovering format string vulnerability
  • Compromising a secured Linux environment via format string exploitation 
  • Firewall evasion using socket shellcode 

Module 5

Exploiting vulnerabilities on x64 Linux

This section is prepared for students to warm up for the final exam and test all techniques that learned from previous sections on a x64 Linux.

  • X64 stack overflow
  • X64 ASLR bypass
  • X64 NX bypass
  • Practical labs (Video)

Final exam

  • All students must capture the flags by compromising vulnerabilities in Linux machines.
  • Each topic has its own flag.
  • Students must reach at least 85% score to obtain the certificate.
