Dozens of tutorials on how to crack WEP are already all over the internet using this method. Seriously—Google it. This ain't what you'd call 'news.' But what is surprising is that someone like me, with minimal networking experience, can get this done with free software and a cheap Wi-Fi adapter. Here's how it goes.
What You'll Need
Unless you're a computer security and networking ninja, chances are you don't have all the tools on hand to get this job done. Here's what you'll need:
- A compatible wireless adapter—This is the biggest requirement. You'll need a wireless adapter that's capable of packet injection, and chances are the one in your computer is not. After consulting with my friendly neighborhood security expert, I purchased an Alfa AWUS050NH USB adapter, pictured here, and it set me back about $50 on Amazon. Update: Don't do what I did. Get the Alfa AWUS036H, not the US050NH, instead.The guy in this video below is using a $12 model he bought on Ebay (and is even selling his router of choice). There are plenty of resources on getting aircrack-compatible adapters out there.
- A BackTrack Live CD. We already took you on a full screenshot tour of how to install and use BackTrack 3, the Linux Live CD that lets you do all sorts of security testing and tasks. Download yourself a copy of the CD and burn it, or load it up in VMware to get started.
- A nearby WEP-enabled Wi-Fi network. The signal should be strong and ideally people are using it, connecting and disconnecting their devices from it. The more use it gets while you collect the data you need to run your crack, the better your chances of success.
- Patience with the command line. This is an ten-step process that requires typing in long, arcane commands and waiting around for your Wi-Fi card to collect data in order to crack the password. Like the doctor said to the short person, be a little patient.

Crack That WEP
To crack WEP, you'll need to launch Konsole, BackTrack's built-in command line. It's right there on the taskbar in the lower left corner, second button to the right. Now, the commands.

First run the following to get a list of your network interfaces:
The only one I've got there is labeled
ra0
. Yours may be different; take note of the label and write it down. From here on in, substitute it in everywhere a command includes (interface).Advertisement
Now, run the following four commands. See the output that I got for them in the screenshot below.

If you don't get the same results from these commands as pictured here, most likely your network adapter won't work with this particular crack. If you do, you've successfully 'faked' a new MAC address on your network interface, 00:11:22:33:44:55.

Now it's time to pick your network. Run:
To see a list of wireless networks around you. When you see the one you want, hit Ctrl+C to stop the list. Highlight the row pertaining to the network of interest, and take note of two things: its BSSID and its channel (in the column labeled CH), as pictured below. Obviously the network you want to crack should have WEP encryption (in the ENC) column, not WPA or anything else.

Like I said, hit Ctrl+C to stop this listing. (I had to do this once or twice to find the network I was looking for.) Once you've got it, highlight the BSSID and copy it to your clipboard for reuse in the upcoming commands.

Now we're going to watch what's going on with that network you chose and capture that information to a file. Run:
Where (channel) is your network's channel, and (bssid) is the BSSID you just copied to clipboard. You can use the Shift+Insert key combination to paste it into the command. Enter anything descriptive for (file name). I chose 'yoyo,' which is the network's name I'm cracking.

You'll get output like what's in the window in the background pictured below. Leave that one be. Open a new Konsole window in the foreground, and enter this command:
Here the ESSID is the access point's SSID name, which in my case is
yoyo
. What you want to get after this command is the reassuring 'Association successful' message with that smiley face.Advertisement
You're almost there. Now it's time for:
Here we're creating router traffic to capture more throughput faster to speed up our crack. After a few minutes, that front window will start going crazy with read/write packets. (Also, I was unable to surf the web with the
yoyo
network on a separate computer while this was going on.) Here's the part where you might have to grab yourself a cup of coffee or take a walk. Basically you want to wait until enough data has been collected to run your crack. Watch the number in the '#Data' column—you want it to go above 10,000. (Pictured below it's only at 854.)Advertisement
Depending on the power of your network (mine is inexplicably low at -32 in that screenshot, even though the
yoyo
AP was in the same room as my adapter), this process could take some time. Wait until that #Data goes over 10k, though—because the crack won't work if it doesn't. In fact, you may need more than 10k, though that seems to be a working threshold for many.Advertisement
Once you've collected enough data, it's the moment of truth. Launch a third Konsole window and run the following to crack that data you've collected:
Here the filename should be whatever you entered above for (file name). You can browse to your Home directory to see it; it's the one with .cap as the extension.

If you didn't get enough data, aircrack will fail and tell you to try again with more. If it succeeds, it will look like this:

The WEP key appears next to 'KEY FOUND.' Drop the colons and enter it to log onto the network.
Problems Along the Way
With this article I set out to prove that cracking WEP is a relatively 'easy' process for someone determined and willing to get the hardware and software going. I still think that's true, but unlike the guy in the video below, I had several difficulties along the way. In fact, you'll notice that the last screenshot up there doesn't look like the others—it's because it's not mine. Even though the AP which I was cracking was my own and in the same room as my Alfa, the power reading on the signal was always around -30, and so the data collection was very slow, and BackTrack would consistently crash before it was complete. After about half a dozen attempts (and trying BackTrack on both my Mac and PC, as a live CD and a virtual machine), I still haven't captured enough data for aircrack to decrypt the key.

So while this process is easy in theory, your mileage may vary depending on your hardware, proximity to the AP point, and the way the planets are aligned. Oh yeah, and if you're on deadline—Murphy's Law almost guarantees it won't work if you're on deadline.
Got any experience with the WEP cracking courtesy of BackTrack? What do you have to say about it? Give it up in the comments.

An internet connection has become a basic necessity in our modern lives. Wireless hotspots (commonly known as Wi-Fi) can be found everywhere!
If you have a PC with a wireless network card, then you must have seen many networks around you. Sadly, most of these networks are secured with a network security key.
Have you ever wanted to use one of these networks? You must have desperately wanted to check your mail when you shifted to your new house. The hardest time in your life is when your internet connection is down.
Wifi Crack Software
Cracking those Wi-Fi passwords is your answer to temporary internet access. This is a comprehensive guide which will teach even complete beginners how to crack WEP encrypted networks, easily.
If it's WPA2-PSK passwords you need to crack, you can use aircrack-ng or coWPAtty.

How Do You Crack A Wifi Code Free
Step 1: How Are Wireless Networks Secured?
In a secured wireless connection, internet data is sent in the form of encrypted packets. These packets are encrypted with network security keys. If you somehow manage to get hold of the key for a particular wireless network you virtually have access to the wireless internet connection.
Broadly speaking, there are two main types of encryptions used.
WEP (Wired Equivalent Privacy)
This is the most basic form of encryption. This has become an unsafe option as it is vulnerable and can be cracked with relative ease. Although this is the case many people still use this encryption.
WPA (Wi-Fi Protected Access)
This is the more secure alternative. Efficient cracking of the passphrase of such a network requires the use of a wordlist with the common passwords. In other words you use the old-fashioned method of trial and error to gain access. Variations include WPA-2 which is the most secure encryption alternative till date. Although this can also be cracked using a wordlist if the password is common, this is virtually uncrackable with a strong password. That is, unless the WPA PIN is still enabled (as is the default on many routers).
How To Break Wifi Code
Hacking WEP passwords is relatively fast, so we'll focus on how to crack them for this guide. If the only networks around you use WPA passwords, you'll want to follow this guide on how to crack WPA Wi-Fi passwords instead.
Step 2: What You'll Need
- A compatible wireless adapter:
This is by far the biggest requirement.The wireless card of your computer has to be compatible with the software CommVIew. This ensures that the wireless card can go into monitor mode which is essential for capturing packets. Click here to check if your wireless card is compatible
- CommView for Wi-Fi:
This software will be used to capture the packets from the desired network adapter. Click here to download the software from their website.
- Aircrack-ng GUI:
After capturing the packets this software does the actual cracking. Click here to download the software from their website.
- A little patience is vital.
Step 3: Setting Up CommView for Wi-Fi
- Download the zip file of CommView for Wi-Fi from the website. Extract the file and run setup.exe to install CommView for Wi-Fi. When CommView opens for the first time it has a driver installation guide. Follow the prompts to install the driver for your wireless card.
- Run CommView for Wi-Fi.
- Click the play icon on the top left of the application window.
Start scanning for wireless networks.
CommView now starts scanning for wireless networks channel by channel. After a few minutes you will have a long list of wireless networks with their security type and signal. Now it is time to choose your target network.
Step 4: Selecting the Target Network and Capturing Packets
A few things to keep in mind before choosing the target wireless network:
- This tutorial is only for WEP encrypted networks, so make sure you select a network with WEP next to its name. If you need to crack a WPA encrypted network, follow this tutorial instead.
- Choose a network with the highest signal.
- Each network will have its details in the right column.
- Make sure the WEP network you are choosing has the lowest dB (decibel) value.
Once you have chosen your target network, select it and click Capture to start capturing packets from the desired channel.
Now you might notice that packets are being captured from all the networks in the particular channel. To capture packets only from the desired network follow the given steps.
- Right click the desired network and click on copy MAC Address.
- Switch to the Rules tab on the top.
- On the left hand side choose MAC Addresses.
- Enable MAC Address rules.
- For 'Action' select 'capture' and for 'Add record' select 'both'.
- Now paste the mac address copied earlier in the box below.
We need to capture only data packets for cracking. So, select D on the bar at the top of the window and deselect M (Management packets) and C (Control packets).
Now you have to save the packets so that they can be cracked later. To do this:
- Go to the logging tab on top and enable auto saving.
- Set Maximum Directory Size to 2000.
- Set Average Log File Size to 20.
Step 5: Waiting...
Now the boring part- WAITING!
NOTE: The amount of time taken to capture enough data packets depends on the signal and the networks usage. The minimum number of packets you should capture should be 100,000 for a decent signal.
After you think you have enough packets (at least 100,000 packets), you'll need to export them.
- Go to the log tab and click on concatenate logs.
- Select all the logs that have been saved.
- Do not close CommView for Wi-Fi.
- Now navigate to the folder where the concatenated logs have been saved.
- Open the log file.
- Select File- Export -Wire shark tcpdump format and choose any suitable destination.
- This will save the logs with a .cap extension to that location.
Step 6: Now the Interesting Part... CRACKING!
- Download Aircrack-ng and extract the zip file.
- Open the folder and navigate to 'bin'.
- Run Aircrack-ng GUI.
- Choose WEP.
- Open your .cap file that you had saved earlier.
- Click Launch.
- In the command prompt type in the index number of your target wireless network.
- Wait for a while. If everything goes fine, the wireless key will be shown.
You may also receive a request to try with more packets. In this case wait until more packets have been captured and repeat the steps to be performed after capturing packets.
