What you’ll learn

Format String Vulnerabilities

  • Students will learn practical format string vulnerability concepts for x64 processors
  • Students will learn how to leak memory addresses using format string vulnerabilities on Linux for x64 processors
  • Who Students will learn how to bypass stack canaries on Linux for x64 processors
  • Students will learn advanced Linux Binary Exploitation concepts
  • Students will learn how to use their own tools binary exploitation framework


  • A computer with administrative access, if you want to follow the hands-on exercises.
  • It is good to have knowledge basic on exploit development


This course teaches exploit development concepts for Linux (x86_64) and it is specifically focused on format string vulnerabilities.
This course begins by introducing students to the format string concepts on Linux x86_64 platform (though the concepts remain the same on other architectures too). We will slowly gear towards understanding how to format string vulnerabilities that can be leveraged to exploit other vulnerabilities such as Buffer Overflows. This is clearly taught in the course by showing various practical examples such as bypassing stack canaries and bypassing ASLR.

This is an entry-level to the intermediate level course and we encourage you to take this course if you are interested to learn to exploit development concepts surrounding format string vulnerabilities and memory leaks specifically for 64-bit Intel processors. However, remember that the course involves a lot of assembly language and debugging using a debugger. So, you need patience and passion to learn the concepts taught in the course. This course makes use of a variety of techniques on exploit development and braces yourself if you are willing to learn by sitting in front of a computer. After successfully completing this course, you will be ready to attempt several industry-leading practical cybersecurity certification exams.

Who this course is for:

  • Bug bounty hunters
  • CTF Players
  • Penetration testers
  • Security Auditors
  • Red Team Operators
  • Anyone interested in security
