Learn Wi-Fi Password Penetration Testing (WEP/WPA/WPA2) (Udemy.com)

46+ Videos to teach you how to hack and secure Wi-Fi (WEP, WPA, WPA2, WPA/WPA2 Enterprise)

Created by: Zaid Sabih

Last updated August 2025

Our take

Based on the ratings of 1,758 students, a sample of their written reviews and the syllabus, as the course stood in August 2025. No course pays to be reviewed.

This is a short, focused introduction to attacking and securing Wi-Fi, taught by Zaid Sabih. It runs 5.9 hours over 49 lectures, so think a few evenings, not a bootcamp. The syllabus starts with networking basics, monitor mode and sniffing, then moves to four ways of cracking WEP, WPS attacks, wordlist attacks (including GPU cracking), WPA2 Enterprise and a brief protection section. It was last updated in August 2025. No Linux or hacking background is assumed, but a compatible wireless adapter is a must.

Reviewers like the teaching. They describe the videos as concise, easy to follow and explained in detail, and one says even a non-IT person can pick it up. Most of the 1,758 ratings are four or five stars. The complaints are small but real. One student found some videos mention content that is not in the course. An experienced user says advanced people will fly through it, and another review points out that you need to practice on your own to get comfortable. A two-star reviewer says it only works when the password is weak.

That last point is worth taking seriously. Wordlist attacks only succeed against passwords that are in the list. Treat the course as a beginner's map of how Wi-Fi security breaks, not a recipe for getting into any network. For that purpose it is a sensible, quick first step. Anyone past the basics should look for something deeper.

Best forBeginners who want a quick, practical tour of Wi-Fi attacks and already own, or will buy, a compatible wireless adapter.
Skip it ifYou want to break strong passwords, or you already do pentesting and need advanced material.

Pros

  • Concise videos that reviewers say explain tricky networking ideas simply
  • Covers four WEP methods, WPS, handshake and wordlist attacks, and WPA2 Enterprise
  • Closes with a protection section on how to harden a network against these attacks
  • Updated in August 2025, with no Linux or hacking background needed

Cons

  • Needs a compatible Atheros-type Wi-Fi adapter, and getting it working can be a hurdle
  • Experienced users say the content is basic and over quickly
  • Wordlist attacks only work on weak passwords, which a 2-star reviewer found disappointing
This is a great introduction to network penetration testing, explained very well.
Mike Robinson, a student

Listed for all levels, but really a beginner course. No Linux or hacking needed, though a compatible Wi-Fi adapter is required.

Course Description

Last Update: May 2024


Welcome to my WiFi cracking course where you'll learn how to crack the key and get the password to WiFi networks weather they use WEP, WPA or even WPA2, not only that but you'll also learn how to secure networks from hackers.

This course is highly practical but won't neglect the theory, you will start as a beginner with no prior knowledge about hacking, and it will take you through the basics of networking and how clients communicate with each other, how the different types of WiFi encryptions work, then you'll learn how to use this information to exploit these networks and crack their encryption.

The course is divided into four main sections: 

  1. Networks Basics: in this section you will learn about how networks work, how devices communicate with each other and how the information is transferred in a wireless networks. You will also learn about basic terminology, what is a channel ? MAC address ? what is managed mode ? What is monitor mode  and how to enable it ? what is sniffing and what is it limited to ? so in this section we still don't know much about penetration testing , all we have is a computer and a wireless card connected to it, you will learn how to start gathering information using your wi-fi card (packet sniffing) and you will learn a number of attacks that you can launch without the need to know the password such as controlling all the connections around you (ie: deny/allow any device from connecting to any network),  you will also learn how to overcome some security features that would prevent you from even trying any attacks, you will learn how to discover and target hidden networks and bypass mac filtering weather it is implemented using a black-list or a white-list. .
     

  2. WEP Cracking: Now that you have gathered information about all the networks around you, and found your target, you will learn how to crack the key that the target uses. In this section you will learn four methods to crack WEP encryption. First you will learn the weaknesses in WEP that allow us to crack it, then you will learn the theory behind each method and finally you will learn how to launch that attack against WEP networks and obtain the key, in this section you will learn 4 different methods to crack WEP to make sure that you can crack any WEP network you face regardless of how its configured.

  3. WPA Cracking: in this section you will learn  a number of methods to crack WPA/WPA2 networks, again you will learn the weakness in WPA and theory behind each method first, and then you will learn how to launch the attack against a real network, this section is divided into a number of smaller sections:

    1. Exploiting WPS - In this subsection you will learn how to exploit the WPS feature to gain access to WPA/WPA2 networks without using a wordlist, not only that but you'll also learn how to debug reaver's output and exploit the WPS feature on more routers using reaver's advanced options, you will also learn how to unlock some routers if they lock after a number of failed attempts.

    2. Wordlist Attacks - in this subsection you will learn how to run wordlist attacks to crack the WPA/WPA2 key, you will learn how to use huge wordlists without wasting storage, save the cracking progress so that you can pause and resume the cracking process whenever you want, and you will also learn how to crack the key much faster using the GPU instead of the CPU.

    1. WPA/WPA2 Enterprise - These networks are usually used in companies and colleges, these are secure networks that use WPA/WPA2 but also require users to login with a username and password after connecting, in this subsection you will understand how they work and how to gain access to them.

  4. Protection: At this stage you will know the weaknesses and methods that real life hackers use, therefore it will be very easy for you to secure your network against these attacks. In this section you will learn how to configure your wireless networks so that the above attacks will not work, you will learn what settings need to be changed, how to access the router settings and how to change these settings.


All the attacks in this course are practical attacks that work against real wireless networks in my lab

With this course you'll get 24/7 support, so if you have any questions you can post them in the Q&A section and we'll respond to you within 15 hours.

There is lots of good information in this Wi-Fi hacking course that gets you right to the place you need to be if you are new at this stuff and just need to know where to start. The short concise videos and the information given in them are taught very well, the trainer Zaid is even very knowledgeable and has a good teaching manor. Although if you are an advanced computer user/programmer then you will be slightly let down by the content which you will fly through in no time at all (when you have eventually got your adapter and got it working), and then, as probably the most important section (Cracking WPA/WPA2 passwords using GPU), in the whole course comes up, after you hear the revelation that currently wordlists/brute force are the only way to crack WPA/WPA2 passwords (not counting social engineering/evil twin attacks), you find out that Zaid is using six year old software versions in these very important sections of this course and unfortunately the course builds up a false confidence regarding the techniques shown as a lot happens in six years so this course kinda builds you up with false hope and then smashes you down when you find out the applications used in the WPA/WPA2 cracking section are from 2017 and the latest version needs a powerful GPU to use it. So don’t believe a word about this course being updated for the 1/2023, because it hasn’t. Also be prepared to spend a lot of cash and time. I have gone through about a hundred pounds so far buying Wi-Fi adapters with monitor mode and packet injection that you need for hacking 2.4/5G Wi-Fi. Now I find out if I want to use the latest version app from sections 41/42 where I should have been able to use the cap files I got from the capturing the handshake using the Wi-Fi adapters section but could not. Now I’m probably looking at spending quite a lot more cash, either buying a new PC as I use Mac’s and I only have an old PC which I only use for fixing disk errors on removable drives so it hardly even gets turned on, or try to get a graphics card that will fit in my old slim line i7 PC exclusively used for fixing disk errors and that will support the latest version of Hashcat so I can then use the new method which uses Hcxtools, which are also not even mentioned, again because this course has not been updated. It’s a shame really as there are only a couple of videos that need to be added to make this course relevant in 2023 and all the stuff for spoofing your adapters IP should be left in as well as how to use the different tools, so with a couple of simple additional videos and nothing removed and I’ve already outlined what should be updated/added in my review this course will be gold, so take this as constructive criticism add the new videos for the points I’ve mentioned and update this course for 2023 as already claimed. I even found another video by Zaid (not in this course) that tells you how to make a cloud PC with GPUs which you can find here with a simple google for “CRAZY Fast WPA2 Cracking Using Cloud GPUs” and in this video Zaid mentions no one uses their own machines for cracking passwords. Well this information should be in the course too. To save people wasting time and making them believe they need some all singing all dancing computer to crack passwords hashes. I have now gone and spent more money on a new Windows 11 laptop that set me back £350 brand new for an i5 with 8GB and a 225GB ssd which is now dual booting with Kali on bare metal and as a bonus even the WiFi adapter in the laptop supports monitor mode. So this course including purchase has set me back over £480 does not include my time. I should also mention here that the version of VMWare (again old version of software, note USB 3.1 is enabled differently to what you are shown, make sure you set this properly as its in a completely different place in the new version of VMWare), Kali image supplied does not support all adapters you will have to update and upgrade and then grab the new Realtek RTL8812AU drivers by cloning the latest drivers from GitHub or upgrading manually, this is also not covered in the course and is quite in depth so again if you don’t know how to do this or are not familiar with the command line you will get extremely frustrated and you’ll have to go and find out how to do this on your own and this process alone uses some quite advanced Linux terminal commands which are also not shown. Atheros AR9271 adapters are not affected. I bought myself an ALFA AWUS036ACH v2 (USB-C), and this would not function properly. I nearly sent it back as faulty until I tried the adapter on the version of Kali I got directly from Kali’s website and to my astonishment the adapter started working as it should (You will know if your device is affected as once you have placed your device in monitor mode and you try to deauth a client, nothing will happen, your adapter will just get hot and the LED will go out on your device or it’ll be so dim you cannot see it, that’s even if you have an LED (mine did not light up at all it just gave up and died) however as soon as I installed the latest drivers my card was up and running and I could happily deauth clients from any network, however I had already built myself a Deauther using an ESP8266 so really I learned nothing new, just a more expensive and cumbersome way of Deauthering clients, I purchased this course to learn Wi-Fi password hacking, obviously deauthering clients is sometimes part of the process or should I say used to be as the new method doesn’t need any active network connections to capture the handshake, so unfortunately this fact alone makes a lot of the tools you get taught to use redundant, as mentioned a lot changes in six years)). You will understand exactly what I’m talking about when and if you get to those sections and you try to convert your cap file to an hccapx file as the online tool has also been updated. You can however still use cap2hccapx from Hashcat-Utils to convert your file (also no covered), although if you have got this far you will have most likely already read the short hashcat + WPA1/2 tutorial forum post linked on the Hashcat converter page referred to in the videos and you will realise that your last few hours of learning and absorbing are now meaningless. Also support is very limited, yes you get a reply within 15 hours although most of the replies are not really what you want to hear as it’s obvious your comment has not been read properly or maybe it hasn’t been understood as it should or you are just given a blatantly quick Google search copy and paste, some answers can even come across as rude, although this maybe a misunderstanding of the comments in the Q & A section that could also be due to a language barrier or maybe just the wrong attitude judging by some of the answers to student comments. I should also mention that the first 30 or so lectures, probably even more I got fed up with comparing them as they are exactly the same as the first 30 or so lectures in Zaid’s Learn Ethical Hacking from Scratch course. So if you want to start Wi-Fi hacking you can use this course as a starting point just take it with a pinch of salt although again as mentioned a lot of the skills taught are now outdated so even if you get that one instead, yes you will get a lot more information in that course and this course seems to have been thrown together using videos from the Learn Ethical Hacking from Scratch course with a couple more videos thrown in to make up the numbers, although just know it is still outdated. I saw one review for Zaid’s courses mention you can learn all of this from freely available Youtube videos (bet you never thought you’d see free and YouTube in the same sentence), and yes you can, although I didn’t think that was fair as to get everything all in one place in the correct order (well almost, there is mention of what we did with captive portals and we did nothing with captive portals, this is mentioned in video 44. So this video is from an other course and it also talks about how we created a fake access point and none of this is ever mentioned. I certainly don’t remember being shown any of that in this course. Then video 45 goes on to talk more about how we have already been shown how to set up a fake access point in detail (no we haven’t), So it would be nice if those sections were updated so the course doesn’t seem so thrown together as a cash grab), takes away some of the learning curve even though the information is a bit outdated it will still set you on the right track. So don’t get me wrong I enjoyed this course immensely and it has given me the knowledge I needed to know to start me off although as mentioned a lot of this course is outdated and repeated in Zaid’s main course, so until this one has been updated with the latest information on WiFi Hacking I would say for now get the Ethical Hacking course instead as it contains a lot more information you can use as a starting point for the different

By Stefano Conti on 9/2/2020

Great course. Just a remark in section 7: often the instructor refers to topics already covered on previous lessons (i.e. captive portals), but actually they have never been explained. Maybe they were covered on other courses. Nevertheless great course, I particularly appreciate the pragmatic approach with a lot of examples. Definitely a good job.

By Faleke Olajuwon Olawale on 3/11/2020

Perfect for anyone starting out in Wi-Fi Pentesting, and generally trying to understand the loopholes in Wi-Fi security. Zaid is a great instructor, he makes everything easy to understand and he keeps his students up to date with the needed software. The zSecurity team is one of a kind and sincerely I have not been taught with so much clarity and feedback on the internet as i got from zSecurity. Due to this, I have purchased every other course zSecurity has to offer because I simply believe I will get my money's worth and that I will be satisfied at the end of each course! Great Job zSecurity and Zaid, Great Job!

By Muntasir Biojid on 2/9/2020

This was a great course! Zaid walked us all the way from setting up our environment and explaining the basics to executing advanced attacks on real targets. The course TA, Ali Joseph, was very responsive in the Q&A discussion forums and responded in a timely manner and was always helpful. This was my second course from Zaid and I hope to keep going and take all his other courses!

By Rae Griest on 12/11/2019

I enjoyed this course! Zaid is a great instructor he is especially good at making things easy for noobs like me to understand. He walks you thru the most difficult parts with ease I find my self going back to the lectures time and again to make sure I am doing the steps correctly. I get so excited when I can practice what he taught in the class and if I have issues I can message him and I will get an answer in a short time.

By Saif Qureshi on 7/18/2019

Love it amazing I have completed my course I am so satisfied its more then enough I had alots of problem during the course but Mr Zaid's team were always there for me and help me out always Special thanks for Mr Ali Joseph he helped me alot I asked his help for then 40 times and he helped me always Mr Zaid is an amazing teacher I came here with 0 zero knowledge and now I am so proud of my self HIGHLY RECOMMENDED

By PRIYANSHU SINGH on 8/26/2018

This is simply the best Wifi Password penetration course you could find. Even a noob beginner can go through the course and with the help of Zaid and his assistants who constantly clear doubts, anyone can learn how to hack and prevent hacking of Wifi networks very easily. Also the methods shown in the course are truly practical and can be easily applied to real world scenarios as well. AMAZING Course, Thank you ZAID sir

By Luis Grappi on 4/3/2018

The course is very embracing, it teachs all the possibilities that a Wifi network can be and how to hack it. All the topics was aproach in a theoric and a practical way and it was really usefull in the real world. I really learned how to crack any "weak" password. In my opinion, the course can focus a little more in the theorical field about wifi networks, because I really like to learn more about it. By the way, I'm very satisfied with the course and I think everyone who likes the theme will be.

By Benjamin Faulkner on 1/23/2018

This course took a zero all the way to hero. Definitely more to learn and much more practice is needed, but having absolutely no prior experience or knowledge of Linux, network cracking, or anything listed in this course it's made me comfortable in knowing what to do. Would recommend this course to anyone interested. Instructor structured the course to continually build off the prior lesson and moves at a pace that someone who at least knows a bit about computers can follow along without having to pause the video all that often to keep up.

By Marco Antonio Estudillo Carranza on 8/13/2017

Estuvo excelente. Se discutieron las técnicas más usuales de vulnerar una red Wi-FI y Zaid explicó muy bien las técnicas utilizadas. Le doy 4 estrellas porque me hubiese gustado que ahondara un poco más en la explicación de ciertos conceptos que son necesarios saber, pero en general estuvo muy bien explicado todo.
