What you will learn!
Primarily the ability and intuition to discover system-related vulnerabilities.
Computer science knowledge relevant to each challenge.
Hacking as a hobby, hacking as a hobby.
※ "Hacking as a Hobby" content only focuses on legal hacking to contribute to a safe information security ecosystem.

Hacking as a Hobby #4 (Nebula)
▶ After "Hacking as a Hobby #1", are you looking for a system hacking challenge to use more difficult skills ?
▶ Do you want to develop the ability to analyze source code (C language, etc.) that will help with reversing ?
▶ Would you like to try your hand at a system-related challenge at a hacking competition ?
If so, you may be able to get help here.
Here, we'll master the popular wargame Nebula . Based on fully translated Korean materials, we'll practice every challenge from start to finish.
We'll discover and exploit vulnerabilities in Linux systems, widely used as servers , and gradually escalate privileges . Through this, you'll discover that most vulnerabilities are the result of mistakes made by developers who lack security knowledge . You'll witness programs that become hostile due to competition. You'll witness how poor data filtering can lead to program collapse . You'll witness how abuse of privileges can lead to outside interference . You'll also witness how poorly applied security knowledge can lead to certain functions being replaced with others .
You'll learn how to discover and mitigate system-related security vulnerabilities through a variety of scenarios. Specifically, you'll cover theory and practice on vulnerabilities related to permissions (general/special), relative paths, environment variables, input filtering, schedulers, password hashes, code injection, cleartext communication, legacy open source, race conditions, variable initialization, library hooking, data encryption, file attributes, deserialization, permission checks, and exception handling.
[Q1] I didn't take "Hacking as a Hobby #1-3." Is it okay to start from here?
[Ans] If you have at least basic Linux system skills (connection, compilation, navigation, text editing, etc.) , this shouldn't be a problem. If you don't, we recommend separate learning or taking the most relevant course, "Hacking as a Hobby #1."
[Q2] What abilities will you acquire when you complete the course?
[Ans] You will learn how to exploit various vulnerabilities in the Linux environment. You will gain more advanced skills in addressing the aforementioned vulnerabilities than before, enabling you to develop more secure programs. Additionally, the extensive source code analysis included will be helpful for future reversing challenges.
