+
+Having a good environment is a must when you want to do binary exploitaton. Here I will show you how to set up a simple environment using Ubuntu and WSL2
+so you can straight up jump into finding and writing your exploits.
+
+## Agenda
+
+Things we will be setting up:
+- Ubuntu inside our Windows WSL2
+- Pwntools library for writing exploits
+- PwnDbg for debugging and finding vulnerability on programms
+
+## Setting up Ubuntu on WSL2
+
+Change WSL version to 2
+```bash
+wsl --set-default-version 2
+```
+<img src="img/Pasted image 20241209090017.png">
+<hr>
+
+Searching for our distribution in the online marketplace
+```bash
+wsl --list --online
+```
+<img src="img/Pasted image 20241209090045.png">
+<hr>
+
+Installing our distribution with a suitable version. Here I will be instaling Ubuntu 24.04 which comes under their LTS
+```bash
+ wsl --install -d Ubuntu-24.04
+```
+<img src="img/Pasted image 20241209090109.png">
+<hr>
+
+After the installation, it will prompt you to set up a user with a password. After which it will drop you to your user shell
+and you should be able to see something like this.
+<img src="img/Pasted image 20241209091105.png">
+
+### Configuring 32-bit environment
+Since the distribution we installed is of 64-bit, we must set it up to run 32-bit programs as well. Its very common in CTFs that we receive 32-bit binaries.
+
+Installing all the necessary packages and libraries.
+```bash
+sudo dpkg --add-architecture i386 
+sudo apt-get update
+```
+<img src="img/Pasted image 20241209091403.png">
+<hr>
+
+```bash
+sudo apt install build-essential
+```
+<img src="img/Pasted image 20241209091547.png">
+<hr>
+
+```bash
+sudo apt install gcc-multilib
+```
+<img src="img/Pasted image 20241209091733.png">
+
+## Setting up PwnTools library
+Pwntools is a CTF framework and exploit development library. Written in Python, it is designed for rapid prototyping and development, and intended to make exploit writing as simple as possible.
+```bash
+sudo apt-get update
+sudo apt-get install python3 python3-pip python3-dev git libssl-dev libffi-dev build-essential
+python3 -m pip install --upgrade pip
+python3 -m pip install --upgrade pwntools
+```
+<img src="img/Pasted image 20241209092006.png">
+
+### Working around the PIP upgrade error
+<img src="img/Pasted image 20241209092036.png">
+
+There are many solutions to it. The best and the recommended one is to set up a virtual environment. 
+The second would be to use the `--break-system-packages` tag with our pip command and
+the third is to set up a config so that we dont have to pass the tag everytime we use pip.
+
+{{< alert iconColor="#FADFA1" >}}
+**NOTE!** I would still recommend to set up an virtual environment!
+{{< /alert >}}
+
+Lets set up a config for our pip
+```bash
+mkdir .config
+mkdir .config/pip
+touch .config/pip/pip.conf
+```
+
+edit `pip.conf`
+```ini
+[global]
+break-system-packages = true
+```
+
+Now we should be able to continue our installing without any errors.
+<img src="img/Pasted image 20241209092615.png">
+<img src="img/Pasted image 20241209092706.png">
+<hr>
+
+We can confirm our installation by loading the library into Python
+<img src="img/Pasted image 20241209093218.png">
+
+## Setting up PwnDbg
+PwnDbg is a GDB plug-in that makes debugging with GDB suck less, with a focus on features needed by low-level software developers, hardware hackers, reverse-engineers and exploit developers.
+
+First lets start by installing gdb
+```bash
+sudo apt install gdb
+```
+<img src="img/Pasted image 20241209115301.png">
+<hr>
+
+Installing and setting up PwnDbg
+```bash
+git clone https://github.com/pwndbg/pwndbg 
+cd pwndbg 
+./setup.sh
+```

+
+## FAQ
+### What to do after this?
+
+Well, I would suggest installing a code exitor such as [VSCode](https://code.visualstudio.com/) on your host machine for you to write exploits or you can be a chad and install neovim on your linux.
+
+After that you can set up a disassembler and decompiler of your choice. There are many to choose from but these are some of my picks:
+- [Ghidra by NSA (yes the NSA)](https://ghidra-sre.org/)
+- [IDA by Hex Rays](https://hex-rays.com/)
+- [Binary Ninja by Vector 35](https://binary.ninja/)
+- [Cutter by Rizin](https://cutter.re/)
+
+Now that you are all set, the only thing left is to start hacking and writing exploits
