Cracking WEP Encryption with Aircrack in Backtrack 4

[alexk77ae]

Do you have any written instructions? I just bought the awus036h, and use backtrack R5. Its ok if there are technical words. I graduated cisco network accademy. im interested in instruction on WPA WPA2 and WEP thank you.

[alban358]

damn i dont no nothing just to log in in facebok

[SabinIsStupid]

Does the AWUS036H device work out of the box for BT 3, 4, 5?

[brodygates]

Alfa AWUS036H does work for windows 7 / xp ........ how much for this card ..... does it have anttena......... is the anttena detachable??

in the 3rd console enter: aireplay-ng -1 0 --a (bssid) wlan0

then wait for the #data in the 2nd window u opened to reach atleast 20000 or 5000

then in a new console window type : aircrack-ng wep-01.cap

it will say password decrypted successfully next time u enter that wireless use he password u found.

[acsdon]

I CRACKED 3 KEYS USIN A SIMPLE FORMULA:

put ur card in monitor mode.

the go to konsole and enter: airodump-ng wlan0 (this will show a list of networks)

copy the bssid of the internet u wanna crack.

open new console win. without closin 1st one.

the enter: airodump-ng -w wep -c (channel no after -c) --bssid (bssid after --bssid) wlan0

then you will recieva lot of #data

open new console window and close the first one showin list of networks.

in the new console enter: written in next post

thanks.. your a life saver..

[ebby4u]

can you send me a video of WPA cracking? to j_kob102@yahoo.com

[DjViOd]

nice accent :D

[Stutodude]

works fine until airodump-ng mon0

[MadMikeSCQ]

you saved me a headache that was already rolling on! Thank you!

[nexthacker007]

at 3:20 what is my file name here airdump-ng [channel of access point] --bssid mac address of access point] --ivs -w [FILENAME???????] mon0

[camataru26]

7"75 file =???? pls

[camataru26]

7"75 file =???? pls

[mripod64]

Finally! someone who puts this into simple terms, iv been working on this project for 3 days! thank you so much for helping me, i will subscribe just cause it worked.

[zazzzmannn]

what method do you use to join the network after cracking, and does the key have to be translated from hex to ASCII before use?

[SalmanAbbas0]

is it for n900

[bowflexx99]

what did you click to stop the airodump right when you got your access point?

[BajeMonde23]

Do you hear about the new WPA Encryption ?

[BajeMonde23]

Hey do you know how to fix the random channel problem?

Went I do that part, on top it say: fixed channel mon0 (and then I get random channel.number) Why ? :(

Everything work before and now mystery came, I try allot of stuff that is out there on the web but no luck at all. I'm using usb wusb600n wireless adapter, Everything I do is in vmware ubuntu 9.10.

Hope you can help me, Thanks.

[AnThOnYrox8]

@BajeMonde23 have to end the previous task, ( the firs one, that searches for all channels) using control + c

[BajeMonde23]

@AnThOnYrox8, It work Thanks men !

[SubnetMask]

Thanks a lot, this vid REALLY helped!! *like, favourite* :)

[raxiboy2050]

can u tell me what i need 2 download fist plz

[Boooro123]

great tutorial....

thank you very much :)

[PUNKROCKINTHISSHIT]

okay now if only i could find a TUT on how to turn the key into the passphrase, im trying to prove to my friend i can access his router without him telling me te new passphrase, so far i have gotten the keys but i dunno how to turn the keys into passphrases. the situation plays out like this "you cant get my network password."

me "bet i can."

tim "go ahead, ill even make it a WEP."

me "your passphrase is ------ "

the only problem is all i can say is "your encryption key is -------"

[JAYJAY1787]

i gotta quick question it was working find when i put the command airodump-ng wlan0 it well scan it n pick up networks around me now i do it again it doesnt show me any net works at all any ideas?

[0igo]

hey im trying to crack a wifi but i do not have an internet connection. there are a whole bunch of internet sites around me but i do not have an internet connection myself to crack them. is there anyway to crack their internet without being connected yourself?

[gaurav2351]

Hii!! I followed each and every step of the tutorial but the problem is i am not receiving any packets and so their is nothing in the dump to be attacked.. What am i doing wrong??

[rickrocker]

At 5:23 I enter the aireplay-ng command and both the airodump and aireplay consoles stop.

The airodump console says "read failed: network is down, Interface mon0: ioctl(SIOCGIFINDEX) failed: No such device, Can't reopen mon0

The aireplay console says "[time] Sending Authentication request (Open system)read failed: Network is down, wi_read(): Illegal seek

I'm using BT4 and the same usb device as you. Any advice?

[multitaskingmale]

@rickrocker It sounds as though the adapter is having difficulty receiving while injecting packets. You can try to use the wireless adapters original interface address (usually wlan0 or wifi0) instead of mon0, as this might work. The original interface will still be in monitor mode and allow packet capture, as you have run the airmon-ng program. If that doesn't work, try stopping and restarting the interface and re-running the airmon-ng program. It's an issue with it being placed in monitor mode

[rickrocker]

@multitaskingmale Thanks for the prompt reply. I've already tried those actions with no joy. I did some research and I think I might have to path the BT4 drivers. I'm not sure if it will work but I'll know when I find out how and when I have the time to try. :)

[Afiso]

@rickrocker Go to Internet ---> Wicd Network Manager.

Look if your wireless is on

[rickrocker]

@Afiso Thanks for replying. That wasn't it. It turns out, I wasn't close enough to my target... I guess?

[jeroeniskoning]

Thank you for sharing

[joeypesci]

Good vid apart from screen capture quality is so low can't read what you're typing

[multitaskingmale]

@joeypesci Make sure you have your subtitiles turned on on YouTube, as all the commands I type in I have displayed as text on the screen, which is perfectly readable. Hope that helps

[joeypesci]

@multitaskingmale Ah right, thanks.

[purplehaze6t9]

hello, how are you. i am going to buy a new keyboard and give that a try,and i really like the idea of booting from usb with backtrack i am going to try that. i have the vmworkstation for Penetration Testing. so i am trying to get all the knowledge i can so when i saw your video tutorial i had to ask some questions lol. i hope you make more video tutorials soon they are very helpful. but i wanted to say thank you for your help & advice. "god bless" ben.

[purplehaze6t9]

hello,very good tutorial.i have a couple questions i just ordered my Alfa AWUS036H wireless adapter the 500mw.the first should i use vmware or live cd. the second is.. when i type a command in backtrack 3 or 4 it does not reconize the command but i can copy and paste them just fine. i would appreciate any help. thank you "god bless" ben

[multitaskingmale]

Hi Ben, the Alfa adapter should work in both the Live CD and VMWare. Backtrack comes with the neccessary drivers, and VMWare should "pass" the USB port through to the VM Appliance.

With regard to the commands not working, it may be a keyboard problem. I've seen in the past that some USB keyboards for example are not recognised by Backtrack. I'm assuming whe you say it Copies & Pastes, that you are using the mouse to do this.

[multitaskingmale]

Incidentally, the choice between running a Live CD or a VM Machine depends on what you want to achieve. A Live CD is perfect for quickly booting into any PC that allows booting from CD. You can also make a bootable USB drive as well, which is a fantastics way to make your Backtrack "persistant", in that any changes that you make will be saved to the drive. It's like installing it to a local hard drive, but makes it portable.

[multitaskingmale]

A VMWare solution is fantastic if you are learning about Penetration Testing, as it allows you to run multiple machine images on the same host machine, so you could have an image running Backtrack, a couple of windows machines, linux machines etc. This allows you to effectively carry your own "virtual network" around with you to test. It also means that if you suddenly corrupt one of the machines, you can simply "rollback" the image. I guess it depends what you want to achieve in your "research"
