🧠 Brainpan – Buffer Overflow (TryHackMe)

This repository contains the Python 3 scripts I used to solve the Brainpan machine on TryHackMe, which focuses on exploiting a classic buffer overflow vulnerability in a Windows .exe binary.

⚠️ Educational use only. All material is intended for learning purposes in controlled environments (CTFs / labs).

---

📌 Machine Overview

Brainpan is a beginner–intermediate level machine that introduces fundamental concepts such as:

• Buffer overflow exploitation in Windows binaries (.exe)
• EIP control
• Payload creation and testing
• Remote exploitation via TCP sockets
• Exploit automation using Python 3

---

🛠️ Repository Contents

📂 Included scripts:

• Scripts to:
  • Identify the correct offset
  • Verify EIP control
  • Send custom payloads
  • Automate interaction with the vulnerable service
• Clean, commented, and reusable code
• Written entirely in Python 3 using standard libraries

All scripts are intended to be executed from Linux-based systems (Kali / Parrot / similar).

---

🚀 Usage

Clone the repository, navigate into the directory, and run the scripts according to the exploitation stage:

git clone https://github.com/yourusername/brainpan-buffer-overflow.git
cd brainpan-buffer-overflow
python3 exploit.py

Remember to change the IP Address and the port in each file!
