Learn Python & Ethical Hacking From Scratch (Udemy.com)

Write 20+ hacking programs to learn hacking and programming at the same time | No prior knowledge required

Created by: Zaid Sabih

Last updated November 2025

Our take

Based on the ratings of 21,548 students, a sample of their written reviews and the syllabus, as the course stood in November 2025. No course pays to be reviewed.

Zaid Sabih teaches Python and ethical hacking at the same time, and the hook is that every section builds a working tool: a MAC changer, an ARP spoofer, a packet sniffer, a keylogger, a cross-platform backdoor, a web vulnerability scanner. The syllabus shows 184 lectures across 20 sections, about 25 hours in all, with roughly 139,000 students enrolled. It is aimed at people with no Linux, programming or hacking background, and several reviewers describe themselves as exactly that crowd.

Students praise the structure. Reviewers say Zaid explains each attack in plain language before writing the code for it, and the balance of theory and practice suits the subject. The rating breakdown backs that up: about 20,000 of the 21,500 reviews are four or five stars. The low-star reviews are consistent though. The course dates from 2018, and several recent reviewers say commands are obsolete, some links are dead, the virtual machine is flaky, and parts of the code no longer run. One experienced Python programmer felt he was mostly watching Zaid code rather than learning the language.

The listing says it was updated in November 2025, but complaints about aging material continue into 2026, so expect to troubleshoot. Some sections still cover Python 2. There are seven assignments and no quizzes or coding exercises, so practice depends on building the tools alongside the videos. Among the ethical hacking courses we compare, this is the one to pick for people who want to write their own tools rather than only run existing ones. Recommended, with patience for setup.

Best forComplete beginners who want to learn Python by writing real hacking tools instead of doing exercises first.
Skip it ifYou already know Python and want the modern web stack; reviewers say the HTTP material and some commands are dated.

Pros

  • Every section ends with a tool you built: MAC changer, network scanner, DNS spoofer, keylogger, backdoor, web crawler
  • Reviewers say the pacing and plain-language explanations work well for people with zero coding background
  • About 64 percent of 21,500 reviews are five stars, and repeat students say Zaid's courses are consistently well structured
  • Covers networking, malware and web hacking in one 25-hour package, with 15 caption tracks

Cons

  • Recent one-star reviews report obsolete commands, dead links and a virtual machine that no longer behaves
  • Still teaches Python 2 alongside 3, and the HTTP-era web material felt dated to an experienced programmer
  • No quizzes or coding exercises, so it is easy to watch Zaid code without really learning Python
The course is so interesting and the pacing is excellent for a newby like me. So well explained and enjoyable to go through.

Course Description

Last Update: May 2024

Welcome to my comprehensive course on python programming and ethical hacking. The course assumes you have NO prior knowledge in any of these topics, and by the end of it you'll be at a high intermediate level being able to combine both of these skills to write python programs to hack computer systems exactly the same way that black hat hackers do. That's not all, you'll also be able to use the programming skills you learn to write any program even if it has nothing to do with hacking.

This course is highly practical but it won't neglect the theory, we'll start with basics of ethical hacking and python programming and installing the needed software. Then we'll dive and start programming straight away. You'll learn everything by example, by writing useful hacking programs, no boring dry programming lectures.


The course is divided into a number of sections, each aims to hack a specific system!  You'll first learn how this system works and its weaknesses, then you'll lean how to write a python program to exploit these weaknesses and hack it. As we write the program I will teach you python programming from scratch covering one topic at a time. By the end of the course you're going to have a number of ethical hacking programs written by yourself (see below) from backdoors, keyloggers, credential harvesters, network hacking tools, website hacking tools and the list goes on. You'll also have a deep understanding on how computer systems work, how to model problems, design an algorithm to solve problems and implement the solution using python .


As mentioned in this course you will learn both ethical hacking and programming at the same time, here are some of the topics that will be covered in the course:


Programming topics:

  • Programming in python 2 and 3.

  • Using modules and libraries.

  • Variables, types, etc.

  • Handling user input.

  • Reading and writing files .

  • Functions .

  • Loops .

  • Data structures.

  • Regex.

  • Decision making.

  • Recursion.

  • Threading.

  • Object oriented programming.

  • Packet manipulation using scapy.

  • Netfilterqueue.

  • Socket programming.

  • String manipulation.

  • Exceptions.

  • Serialisation.

  • Compiling programs to binary executables.

  • Sending & receiving HTTP requests.

  • Parsing HTML.

  • + more!

Hacking topics:

  • Basics of network hacking / penetration testing .

  • Changing MAC address & bypassing filtering .

  • Network mapping.

  • ARP Spoofing - redirect the flow of packets in a network.

  • DNS Spoofing - redirect requests from one website to another.

  • Spying network devices / clients.

  • Analysing network traffic such as usernames, passwords, visited urls, etc.

  • Inject code in pages loaded by computerd connected to the same network.

  • Replace files on the fly as they get downloaded by computers on the same network.

  • Detect ARP spoofing attacks.

  • Bypass HTTPS.

  • Create malware for Windows, Apple Mac OS and Linux.

  • Create trojans for Windows, Apple Mac OS and Linux.

  • Hack Windows, Apple Mac OS and Linux using custom backdoors.

  • Bypass Anti-Virus programs.

  • Steal credentials using fake prompts .

  • Display fake updates .

  • Use own keylogger to spy on everything typed on Windows & Linux.

  • Basics of website hacking / penetration testing .

  • Discover subdomains .

  • Discover hidden files and directories in a website .

  • Run wordlist attacks to guess login information .

  • Discover and exploit XSS vulnerabilities .

  • Discover weaknesses in websites using own vulnerability scanner.


Programs you'll build in this course:

You'll learn all the above by implementing the following hacking programs

  • mac_changer - changes MAC Address to anything we want .

  • network_scanner - scans network and discovers the IP and MAC address of connected clients.

  • arp_spoofer - runs an ARP spoofing attack to redirect the flow of packets in the network allowing us to intercept data.

  • packet_sniffer - filters intercepted data and displays usernames, passwords, visited links, etc.

  • dns_spoofer - redirects DNS requests, eg: redirects requests to from one domain to another.

  • file_interceptor - Intercepts downloads and replaces them with any file we want .

  • code_injector - injects code in intercepted HTML pages.

  • arpspoof_detector - detects ARP spoofing attacks.

  • execute_command payload - executes a system command on the computer it gets executed on.

  • execute_and_report payload - executes a system command and reports result via email .

  • download_and_execute payload - downloads a file and executes it on target system .

  • download_execute_and_report payload - downloads a file, executes it, and reports result by email .

  • reverse_backdoor - gives remote control over the system it gets executed on, allows us to

    • Access file system.

    • Execute system commands .

    • Download & upload files.

  • keylogger - records key-strikes and sends them to us by email.

  • crawler - discovers hidden paths on a target website .

  • discover_subdomains - discovers subdomains on target website .

  • spider - maps the whole target website and discovers files, directories and links.

  • guess_login - runs a wordlist attack to guess login information.

  • vulnerability_scanner - scans a target website for weaknesses and produces a report with all findings .


As you build the above you'll learn:

  • Setting up a penetration testing lab to practice hacking safely.

  • Installing Kali Linux and Windows as virtual machines inside ANY operating system.

  • Linux Basics .

  • Linux terminal basics .

  • How networks work .

  • How clients communicate in a network.

Zaid sir is best teacher From the start of my journey of Cybersecurity, I am following him only, Not only on Udemy but all the platform i can afford to be. Thank you Sir. Devanshu

By John macdonald on 5/21/2026

This tutor is a very good tutor. The course is so interesting and the pacing is excellent for a newby like me. So well explained and enjoyable to go through. Really really impressed!

By Valerie Saenz on 2/4/2026

I've taken other courses from Zaid, just like the others these are structured so well with a balance of theory and then actual practice which is perfect for this kind of subject.

By Brian Degen on 1/21/2026

Course was great for what I was trying to get out of it, a refresher to knowledge already learned. A little difficult to complete the hands-on practical exercises based on the system I was using for conducting the training.

By Robert Navarro on 1/5/2026

I love how he explains EXACTLY what to do and why, only what I need, absolutely no mention of ENIAC and how many rooms it filled or any of the billions of useless facts we never needed to know :P

By Trojan Op on 1/3/2026

his teaching style is VERY PRODUCTIVE he teaches EVERYTHING with an example. He focuses on the thing you ACTUALLY will need not useless stuff everything he teaches is practical practical and PRACTICAL he will get it in your BRAIN

By Rich Pace on 12/12/2025

vm is dodgy, half the code no longer works, web browsing non functional with iptables set for nfque. I get the course is multiple years old so probably little support.

By P Alexander S Cole on 12/8/2025

I started this course with zero hacking knowledge, though I started coding in python which I don't face difficulty with, this course expose me so much to hacking and networking. The instructor teaches well.

By Stuart Grayson on 12/4/2025

Good intro into Python as never done any python coding, looks a good course for beginner's Course goes into great detail on the how to and at a good pace to also do some side testing. Worth going through - really enjoyed it

By Aditya Ranjan Swain on 10/25/2025

Honestly one of the best entry to mid level cyber security courses out there . After successfully finishing this , 2 times , i can say my fundamentals and overall usecase of different functions , libraries and tools has increased . This is how you teach , explaining the real process line by line step by step ( even the most redundant ones) so that everyone regardless of coding proficiency or cyber sec knowledge can know and learn ,a lot from this . Looking forward to more courses from Zaid .
