Description: Welcome to Part 3 of the WLAN Security Megaprimer! Please start this series by watching Part 1 http://www.securitytube.net/video/1756, if you have not done so already.
In Part 3, we will understand the basics of Beacon frames and how access points use it to advertise their presence to clients in the same RF vicinity. We will whip out Wireshark and understand these packets down to a microscopic detail. Then, we will also look at how to use MDK3 in BT4 to create a Beacon frame flood to fool all the wireless clients in the vicinity.
Feedback good/bad/constructive ... all welcome :) Please leave your comments behind.

Another good one, Vivek.
Interesting... Thank you for sharing sir :)
This is great. I've been wanting to learn more about using Wireshark in general and learn more regarding wireless security, and I get both in these videos! Thanks again Vivek!
@WCNA @lorddicranius Thanks! I am glad you guys are enjoying the videos!
@Saisudha No Sir(s) here on ST :) Just Vivek :)
You forgot that linux distributions are also capable seeing AP's :D
@netinfinity Loosely speaking my MAC and iPhone are both based on FreeBSD :) So, actually i did not show any windows distros :)
I dont have any words to tell you.....Video quality is fantastic....Thank you very much.....
I really enjoy learning from your videos.
You have a very clear and student friendly approach. I have watched other videos and was able to copy/parrot the action. but most of them are more about showing off than they are educational. I really appreciate your efforts in providing such solid classes.
Thanks!
sorry for the OT but why's that not possible to download this video?
I actually came indoors from sitting in the sun with a big glass of Southern Comfort to watch the latest video in this series! The whole family sit and watch them (I dread to think what our kids will turn out like!)
Vivek is fantastic - he's like the IT tutor you wished you had and I really want to thank him for taking his free time to make all his fantastic videos - and - create this site.
Can I make a request Vivek? Would you mind adding a little talk on 'add hoc' wireless networks? I've never really understood the thinking behind them, and apparently they are a major source of security issues (second to rogue access points in the corporate network).
@Vishal @Sender Thanks! Appreciate your kind words
@Cypher I have enabled downloads on Vimeo. It should work now.
@Blackmarketeer Haha :) Thanks man! I am glad you are enjoying the videos so much. To answer your question - yes, absolutely. Ad-Hoc networks will be covered within the next 3 videos. This whole series will be around 15 - 20 videos and my task is to finish them all by this Saturday :)
Top man!
@Cypher You can download it easily using firefox download helper...
Vivek I really really likes you videos and even your personality Thank you very much.........looking forward to see more
Vivek, I really love you!
I cannot say how much I like your vids, from beginning when you first post your vids about Assembler and Bufferoverflows over all the other Megaprimers up to this serie.
I really like how much you go into details, i read many books about IT Security, but your Videos always go down into details, I never heared before. This site is really the best source for students, how love IT security. You are a really good teacher and when I watch this videos I absolutly can see, that you love IT Security too! It's really great for me to watch video's from you, so please, please keep on making new video's!!
@Vishal, Cipher You can download the high resolution videos from Vimeo directly
@Dr. Error Thanks my friend! :)
@Juggl3r Wow! thanks for sticking along with ST for such a long time. You won't believe there were times when i really questioned the fact if my videos were even being watched but the community's support kept me going!
excellent detail!
Thank You Sir ! :P
No really This is great ViVek thanks alot
I loved this video Vivek, you have no idea how much havoc I'm going to wreck at cafe's and such ;) I'm moving on to the next one now. I'm gonna keep going until you lose me completely haha
Thanks for everything!

These are some of the best WLAN security educational videos i have ever seen. Well done Vivek!
I really wish that everyone could be as great as you are, and as sharing as you are, many thanks dear Vivek, cant get enough of watching these great videos
Fantastic video series! Thank you for breaking down the steps and making them easy to understand. I've been through a few network security classes and none compare to your video. Thanks!
@hugol, KsA.HaCkEr, Grey_King, tomfromselmonte, Globalization, Jaysin Thanks a ton for all the encouragement my friends! I really appreciate it :) This is what keeps me going. I have posted a lot of new videos in this series, so please do have a look when you get time.
finally I find someone who can break it all down so that it makes sense. Thank you so much for sharing your knowledge and experience.
Have you ever thought of creating your own security podcast show, like Hak5 or something similar?
Keep it up...
Vivek- this is SUPERB. Thanks for taking the time to compile these videos.
I just started watching these videos. They are so great! Detailed and comprehensive. Thanks so much, Vivek! You Rock!
Really really amazing. Hope all thoose video gonna be clear as previous!
Very great introduction to Wireless security, and very good video.
Thanks!
Very concise videos on WLANs. Thoroughly enjoying the instructor-like environment. Kudos!
I really enjoy your videos, you should marry my sister.
I learn more from your short videos than i do in hours of reading texts. I like the new format also. Excellent resource...keep up the GREAT WORK!
Agree with Bender; a few 20-minute videos are more valuable than entire textbooks when they are concise, to the point, and easy to understand. Excellent videos; keep up the good work! (on a side note, what is your day job, Vivek?)
vivek am just starting off on your website an u your great mehn easy and lucid explanations
Thanks 4 the videos vivek sir.........
Great videos vivek.. much appreciated. I wasn't able to capture any packets with wireshark in BT5 but I was able to get it working in BT4R2. I'm fairly new at this so I am probably missing something.
So in BT4R2 I went through all the steps, calling my ssid pwned running at 59 packets/sec. Everything looks good, but Pwned does not appear as a wifi option on my host computer, or my 'victim' laptop. So I don't know whats going wrong.
Ill try to figure it out. but anyways, nice work!
Vivek really good video.
But I have a question, when you said that spoofing wireless bacons is easy, did you refer to making it with mdk3 or to make a simply program?
Thanks for all Vivek
good good I got it to work.. on to part 4!
Thx for those videos, i bought the WiFu course from Offensive Security but your videos are tons of time much clear and complete. Keep going Vivek, keep going ! :-)
Just started to watch these videos - Great work Vivek, I can actually follow what your saying in plain english!
why i can't see the network Pwnd using mdk3 in my android smartphone?
Although I'm only 3 videos into your megaprimer, I have to say that I am hooked. These are the best videos I have seen so far, although to be honest, that may not mean much since I only installed BT5 a few days ago and only received my alfa card in the mail today... Still, I have been scouring youtube, watching hak5, reading tutorials at other sites, and so far your presentations are far superior. I look forward to watching all of them, and as I progress in teaching myself how to program, I look forward to your videos in those areas as well.
I just finished a ceh course and I still learnt so much from you thank you very much Master Vivek
great man. you are the best.
I am really enjoying your videos. Thank you for the wealth of knowledge provided in them.
Thank you for providing such nice video series.I am really learning a lot..you provide great wealth of knowledge. Looking forward to watch all wireless security videos...These are the best video series i am ever watching till now.
This is just brilliant !
Thanks for your videos.
Best way to learn this stuff. Thanks Vivek, you da mannnn !!!!
I've watched a few of your videos now and wow i'm really impressed. Thanks a lot for your effort you are a amazing teacher!!!
Great videos Vivek.
I am trying to follow along and go through all of the same steps you do, but for some reason when I go to /pentest/wireless/ I do not have mdk3. So I am stopped in my tracks. This is for BT5.
Any thoughts?
Please forgive my last post. I was able to locate MDK3 here: /usr/local/sbin.
Hope this helps someone else.
Thanks again for the videos Vivek.
These are very educational wonderful videos! Not only do seem to be a great instructor your speech, and charisma are very very good!
You're the best instructor I've ever had. I always wanted to learn this and now one of my wishes came true. I'm on the 3rd video and I'm just loving it. Thanks!
On the ISO the pages extension is .htm but the links point to .html pages, wich causes an 404 error everytime I click on them.
Hi, Thanks for the video. I tried it but I was unable to see the network on my other PCs/iPhone. I checked wireshark and it looks like the Beacon frames are being broadcast correctly. I'm using the wifi card you suggest and Backtrack 5.
Hi Vivek, I ended up watching your previous video series and I have just started to watch this series. I must say you are doing a great job and thank you so much for these wonderful videos WE STUDENTS really appreciate your efforts :)
Probably the best free education a student can get.
yaar, how do you know so much... besides watching this video i like watching the way u tell stuff, it is more attractive then just listenin to ur voice in previous other videos.
yaar, i am a fast learner, ur videos and you help me lot to learn thing.. i hope u read this comment.. and reply to this :)
I would just like to mention great tutorials getting a education right here.
one thing about mdk3 i see you using backtrack 4 , bt5 is out right now and you have to start the application up and get around by using mdk3 <input> command just so people don't get confused. you cannot access mdk3 using cd /pentest/wireless/mdk3 in bt5
just thought i would leave some feed back
Hello Vivek, I wanted to ask something about the ALFA card used on this course. I bought one because I am planning to do the WLAN Security certification with you and I have read somewhere that I have to set this card to broadcast until 100mW(due to legal issues) and they provide some drivers for Windows to do this, but I am using Ubuntu on my PC. I will be using during the course VirtualBox as well. My question is, do I really need to do this limiting of the antenna broadcasting for the course? and if yes, do you know if there is some driver for ubuntu users. Thank you very much. Luis
V3nCz3ch, i'm not sure what legal restrictions that you're talking about, but you may want to mention the country that you live in. honestly, i'd highly recommend that you install backtrack w/in virtualbox. it has all of the necessary drivers, plus a ton of cool wireless tools such as kismet. i'm using alfa AWUS036H and AWUS036NH w/in backtrack. they're just plug and play.
justme, thank you very much for your reply. What I meant by legal restriction is that in several countries in Europe, this antenna comes with a driver (for windows) so you can reduce the frequency to 100mW. So my concern was that when I tried this antenna (AWUS036H) IN MY Backtrack w/in virtualbox I could see the SSID's around me, so I wouldn't like to get into some troubles because of that :)
Thank you so much Vivek i learnt so much from you:)
Thank you so much for all your effort in providing these videos so clearly. I am Spanish and I assure you that even in my bad English understanding I follow the theoretical and practical parts that you post. I am deeply grateful. I just wonder if it would be possible to put some captions to videos for more Spanish-speaking people can access this source of knowledge. Either that or we end up learning two things at once, wireless security and language. : D Thanks again.
thank you so much sir vivek!
@infowar (or anyone else using BT5)
how exactly do you use the MDK <input> command? I tried to access the directory except using /usr/local/sbin/mdk3 and i keep on getting an error saying that mdk3 isn't a directory, though it is there when i run a ls in the cd
Great Work.... keep going....
"Access to this site has been blocked as per Court Orders" Vimeo blocked! I can understand blocking torrents, but VIMEO?
And from what i've been reading about iframe and XSS, I'm a little skeptic using proxy servers.
Why dont you upload your videos on youTube?
Simple love your videos! Best teacher ever!
Sir,
The Videos are awesome... You are doing a great service to student community. Thank you sir G
AMAZING!!!! man you're amazing :) This is my first time here and i couldn't resist to watch more and more. I wanna know if there is a way for cracking some wifi encryption methods . I am currently working in a new university and I'm installing their wireless and wired network , so i need some help here brother . And i wonder from where i can downloads slides , videos . Appreciate it alot thanks brother
Hi Vivek,
Nice to know some one out there to share his knowledge for free through videos :) your videos are really amazing anyone can get additcted!
I have Netgear WNDA1300 USB adapter runs on Atheros Chipset ; I was succssefull it install it on BT4r2 and was able to capture packets and spoof ssid successfully.
however while pwning ssid ; neither my laptop / smartphone able to see the ssid: i was wondering when i am able to capture spoofed packets why not on my smartphone / laptop
could this behavior be because of my USB adapter has less gain < 1W ( but my smartphone is at a distance of 2ft from my USB adapter who's spoofing)
is there anything i am missing out here
please share your thoughts : glad to hear it from you
Thanks,
Siraj
Other excelent video! Keep the good work!
Excellent work and very helpful knowledge. I had one question regarding one of your first slides. The slide says 3 types of packets. I thought that these were actually frames and not packets. I am still new to the details so I may be wrong but thought I'd ask. Keep up the great work!!!!!
wow.. MDK is really dangerous man..
Keep up the good work .. Thanks !

Thank you for your hard work - very beneficial ...
Great video! I've learned more by watching this video than I have in the last few years of classes, personal research as well as trial and error :) . Keep up the good work!
Good video! I will be adding mdk3 to my toolbox.
Very interesting video. Thanks Vivek!
Just started watching your vids. They are super awesome and you are very good at explaining what is going on. keep up the good work! :)

this tutorial helped me a lot, so thank you Vivek for your kind support,you are awesome
Great video, thanks for all these tutorials Vivek
Thank u Vivek...you make a lot of effort..Good luck
Hello Vivek,
I am an Information Systems Security Student and your Wifi classes rock! They have been extremely helpful in utilizing tools and also explaining the process or steps taken in the use of WIFI. I plan on later testing for this cert. Again keep up the great work and thank you!
Thank you sir ..
Hi Vivek, Excellent job, I would really like to appreciate your efforts. Thanks a lot!
Great. Anything for Windows users ? Actually I support them, don't hack them, but need to test our counter-measures for attacks. Use Omnipeek v6 on win7 32bit with a WUSB600N v2 card.
Tnx,ciao
Vivek - Bravo! Excellent job. You are very thorough and explain how to perform everything very concisely, clearly and with the right amount of detail and attention span! Keep up the good work. This is my first comment after watching 3 videos thus far and they are getting better and better. Very excited. Keep up the good work!
super''''''''''''
great work.............
