Python Hacking: Build 15+ Penetration Testing Tools [2025] | Udemy

Unlock the full power of Python 3 for ethical hacking, malware development, and penetration testing — from absolute beginner to advanced offensive security developer.

This hands-on, practical course is designed for students who want to master ethical hacking and Python programming side by side. You will learn by building 15+ real-world hacking tools from scratch — including reverse shells, botnets, internet worms, keyloggers, FTP/SSH brute forcers, PDF password crackers, and more.

We start from zero — no prior programming or cybersecurity experience needed. By the end, you’ll have the skills to write custom hacking tools, automate attacks, and understand how malicious software is developed and deployed in real-world offensive operations.

What You’ll Learn

Programming Topics (Python 3):

• Socket Programming (TCP, UDP)
• Multithreading & Concurrency
• Python Requests & Subprocess modules
• File I/O, Parsing, Serialization
• Interacting with the OS
• Building CLI tools & automation scripts
• Importing & using modules (e.g., os, socket, threading, subprocess, requests)
• Writing cross-platform code
• Sending and receiving data across networks

Hacking & Malware Development Topics:

• Setting up a penetration testing lab (Linux/Windows VM setup)
• Building fully functional botnets and worms
• Developing a Python backdoor with remote shell capabilities
• Writing a custom keylogger for Linux and Windows
• Automating brute-force attacks on FTP and SSH
• Creating a network scanner and port scanner
• Building a password hash cracker
• Creating PDF password brute force tools and PDF protectors
• Developing trojans and reverse shells
• Evading antivirus and understanding malware detection
• Exploit development and automation using Python

Projects You’ll Build

• FTP Brute Forcer – Try thousands of username-password combinations
• SSH Brute Force Tool – Automate dictionary attacks on SSH servers
• Custom Backdoor – Execute system commands remotely on compromised machines
• Reverse Shell – Establish remote access to victim machines
• Keylogger – Record keystrokes silently and export logs
• Botnet Framework – Deploy multiple agents and control them from a C2 server
• Internet Worm – Build a Python worm capable of propagating across systems
• PDF Cracker – Unlock password-protected PDFs with brute-force logic
• PDF Protector – Secure your PDF files from unauthorized access
• Information Stealer – Exfiltrate saved credentials and sensitive data
• Network Scanner – Identify live hosts and open ports
• Port Scanner – Detect services running on a target system
• Exploit Automation Tool – Launch payloads and automate common attack vectors

Who Is This Course For?

• Aspiring ethical hackers
• Students of penetration testing or cybersecurity
• Python developers looking to apply skills in security and malware development
• Bug bounty hunters seeking to build custom recon/exploit tools
• Intermediate programmers aiming to understand offensive security programming

Why This Course?

Unlike typical coding courses, this course is 100% focused on offensive cybersecurity. Every topic is taught in the context of hacking and real-world attacks. No boring theory. Every concept is demonstrated through live Python coding, real attacks, and malware behavior.

By the end, you will be confident in building your own hacking arsenal and ready to take your cybersecurity knowledge to the next level — whether in penetration testing, malware analysis, or red team operations.

Lab & Environment Setup

• Install & configure Kali Linux, Windows 10, and Ubuntu in VirtualBox
• Set up a safe lab for testing tools without legal risks
• Learn how to test your malware on isolated systems
