Cracking WEP

Hack any WEP wifi network using BackTrack 5r3 crack wep password backtrack 5 r3

This chapter will teach you how to crack the WEP of a wireless network using BackTrack 4 step by step. BackTrack is a free OS available for download at This tutorial is using BackTrack 4, but it should work similar in newer versions. Backtrack is the ultimate security testing OS, and is preloaded with hundreds of tools you can use to hack. We re only going to be using a couple for this tutorial.

Download the BackTrack 4 flavor of your choice. You can either boot the OS using VMware within windows, or you can boot backtrack straight off of a DVD or flash drive. Instructions for each of these methods are on the backtrack website.

Once you have booted up backtrack, it will ask you for a username and password. username: root password: toor

Now type startx and press enter. This will log you into backtrack and you should now see the desktop.

Open a command terminal. You can do this by clicking the black box icon bottom left corner of the screen.

Look for the name of your wireless card, its different for a lot of computers, mine is wlan0, so for the rest of this guide thats what i m going to use. Replace wlan0 in all the following steps with whatever your device name is.

type: macchanger --mac :: wlan0

You will now see all of the wifi networks in range. once you found the one you want to hack, press Ctrl C to stop scanning. Take note of the bssid and channel of the network you want to hack.

type: airodump-ng -c put the channel here -w wephack --bssid enter bssid here wlan0

Keep that window open, now open another command terminal and enter the following in the newly opened terminal:

type: aireplay-ng -1 0 -a enter bssid here -h :: wlan0

type: aireplay-ng -3 -b enter bssid here -h :: wlan0

Now go back to the 1st window, you ll notice a number steadily increasing. Once its over about 10,000 you can attempt to crack the WEP key. If this doesn t work, wait until the is even higher, try again at 15,000 and so on

open a new command window and type: aircrack-ng -b enter bssid wephack-0.cap

You should now see it attempting to crack the WEP key. This could take up to 5 minutes or so depending on how fast your computer is. When its found the key, it will appear on the screen. You can now log into that network using the WEP on the screen :

Usually, for this to work flawlessly, someone has to be currently using the internet on the network you re trying to hack, or else it could take awhile for you to get enough packets to crack the WEP.

It is illegal to steal wireless internet. Only try this on your own network. This guide is for educational purposes only, as with everything in this ebook. Use at your own risk.

- A computer with a wifi card that supports packet injection see more below

- A blank DVD and a DVD drive USB instructions are coming soon

Wifi cards with packet injection support: For a PC, google your wifi card to see if it has packet injection, because there are too many cards to list here.

As far as I know, any intel Mac will work. 1 Download the BitTorrent version faster, still legal since it is open source of BackTrack here, or if you don t have a torrent client download it here. Do not worry, you will not have to install BackTrack 5r3, because, like many Linux operating systems, it is live so you can run it directly from the DVD.

2a  On a Mac, open the ISO file, then launch Disk Utility, click on the ISO, and burn the DVD. You must do this through disk utility and not the Finder, because Disk Utility makes the DVD bootable and Finder makes it into a data DVD.

2b On a Windows 7 PC, double click on the ISO file or if it opens an extraction program, right click and open with disk image burner. If you have a computer that has an earlier version of Windows or does not run Windows, feel free to comment and I will contact you with instructions.

3 Turn on your computer and press they key that allows you to change the boot device; On Macs, the key is alt/option, most PCs are F12, but if that doesn t work google it or comment. Then, use the arrow keys to select the DVD on Macs it is labeled, Windows, even though it is Linux and push enter to confirm.

4 When you see this screen, just push enter and BackTrack will continue loading.

5 Use the arrow keys to select the BackTrack Text - Default Boot Text Mode if it is not already selected and press enter to start booting into BackTrack Live. This may take some time depending on your optical drive speed, however if it takes more than 7-10 minutes restart your computer and try again. My early 2008 iMac booted off it in around 2 minutes

6 Eventually, you will get to this screen or something like it, it may be in a box with the BackTrack background behind it. It all depends on your graphics card. Here you want to type without the quotes startx in order to get the more user-friendly GUI interface

7 On the top bar like the menu bar in OS X, click on the terminal icon the only icon up there on the left next to the menus. Then type without quotes airmon-ng to find out your interface name. My interface and most of yours is called wlan0

8 Type without quotes airmon-ng start yourinterfacename the interface from the last step, like I said mine was wlan0.

10 Follow the steps in the video below. If, after you select your interface, the text Monitor mode enabled does not show up below the interface box, quit the app and open it again. Then retry the steps in this video.

11 Finally, the WEP password should be cracked. If it didn t work, try another method under the Gathering Packets

Note: BackTrack Linux is an operating system specifically designed for hacking networks and network-based services like Facebook, email, etc. More BackTrack tutorials are coming.
