Wep crack centrino

The news here is not that WEP isn't especially secure—that fact is already well-known. What is important to note is the speed with which someone with a Centrino laptop and the proper tools can compromise a WEP-protected network. If you want the most—secure wireless network possible, WPA2 is the way to go. It's part of the Enterprise users can use an authentication server, while home or small business users can use a passphrase.

The following breaks down each script and lists its purpose. This script can be run live with the capturing program, or with an existing capture file. Once the file is processed , the script performs a statistical analysis to determine the most likely key.

Although this script can be wrong, the chances of this occurring are rare. This file will contain a list of all the possible weak IVs that would exist for the given key. Although it does not provide that much information, it can assist in quickly listing BSSIDs and other valuable bits of information. From this short overview on each of the scripts included in WEPCrack, you can see what it can and cannot do. Although this program will crack WEP, allow you to tinker with the algorithm, and even add your own code if you choose, it will not sniff a wireless network for encrypted packets.

If this is your goal, you will need to capture the data first, using either prismdump or Ethereal. WEPCrack installation is simple. However, the requirements for the programs needed to capture the data might be a bit more rigorous.

To see how to install Ethereal, see the Ethereal section earlier in this chapter. Remember that several of these scripts will work on Windows environments. Before using WEPCrack, you will need to collect massive amounts of data. This is not unusual, and is in fact the attack method most WEP-cracking programs use. However, this does mean that you will need to capture roughly seven gigabytes worth of information to be fairly sure you have enough sample data to extract the key.

Again, to do this, you will need either prismdump or Ethereal. Because we have already covered Ethereal in this book, we will now provide some tips on installing prismdump. In addition, you will need to think in terms of decimal form. This is because WEPCrack's scripts use decimal form for input and output. This is an important pointone that will frustrate you if forgotten.

You will need to install this program to get WEPCrack working. Build Ethereal's wiretap library run. 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:. What you want to get after this command is the reassuring "Association successful" message with that smiley face. Here we're creating router traffic to capture more throughput faster to speed up our crack.

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, Pictured below it's only at Depending on the power of your network mine is inexplicably low at 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. Once you've collected enough data, it's the moment of truth. How to crack WEP via a wireless client?
