Preparing the Tools

Ech0

1) Beginner Reversing

The basics of reversing with simple to understand examples

Ech0

2) Stack Buffer Overflows

These are the most common binary exploits, they are there because of insecure functions that do not set a limit to user input, allowing the user to overwrite other memory registers.

Assembly x86_64

As i hit the shellcode buffer overflow binary challenges, i realized that i needed assembly skills, so this is a simple introduction to modern intel Assembly for the x86_64 (64bits) architecture. We make use of the syscalls used to communicate with the Linux Kernel:

1. ✅ Hello World
2. ✅ Hello World Explained
3. ✅ Jumps, Calls
4. ✅ User Input
5. ✅ Math Operations
6. ✅ Reading / Writing Files
7. ✅ Spawning a shell
