Description

During this course, participants will learn programming languages and Shellcode writing. They will gain knowledge in program structure and execution patterns in order to know how to find vulnerabilities in, and exploit, programs and codes to gain control of target systems and applications.

This course covers how to write shellcodes, programs, and tools, essential skills for advanced penetration testers and software security professionals.

How to make the most of this course?

In order to succeed in the course, the following requirements must be met:

  • Participation in all practical laboratories
  • Self-work at home between lessons
  • Repetition of materials, self-learning, performing tasks, etc…

In addition to regular classroom studies, the participant is required to practice at least 10 hours a week in order to gain practical experience in the field.

Real cases studies

Case study #1 (EDA001)
Skype, a free online service that allows users to communicate by voice, video, and chat, was a cause for a bug that allowed hackers to execute malicious code remotely. This bug was leaked and then discovered by Skype themselves; following this, the bug was mitigated and fixed. A group of hackers managed to replicate this bug in the new version, but all they provided is a POC.
Reference
Case study #2 (EDA002)
A group of international cyber activists managed to abuse a vulnerability in an FTP Server; the company rushed to fix the issue, but after months of going back and forth, they were unable to replicate the steps that the cyber group performed. Following this, the company issued a bug-hunting program, rewarding the first to provide a working POC.
