Thanks for posting, this information needs to be known. Dear Writer, I am extremely thankful to you for this informative, clean, pin pointed and easy to understand tutorial. It worked for me as piece of cake. Regards Thank you again. Well, your tutorial was really easy to follow.

Other ones at the default website and some forums were really long and confusing for me, even I am using Linux for over 5 years.

I don't get why those people have written more commands and other shit. Good work. Keep it up! HI, I have same intel agn with hp dv se,Operating system Vista. I em using Vmware and running backtrack 3. I still cannot see my card. Please help me Thanks. All rights reserved. Broadband Forums General Discussions. Telefonica Incompetence, Xenophobia or Fraud?

Console Gaming. If you're using the BackTrack CD aircrack-ng is already installed, with my version of linux it was as simple as finding it with: yum search aircrack-ng yum install aircrack-ng The aircrack-ng suite is a collection of command-line programs aimed at WEP and WPA-PSK key cracking.

The ones we will be using are: airmon-ng - script used for switching the wireless network card to monitor mode airodump-ng - for WLAN monitoring and capturing network packets aireplay-ng - used to generate additional traffic on the wireless network aircrack-ng - used to recover the WEP key, or launch a dictionary attack on WPA-PSK using the captured data.

Setup airmon-ng As mentioned above, to capture network traffic wihtout being associated with an access point, we need to set the wireless network card in monitor mode. To do that under linux, in a terminal window logged in as root , type: iwconfig to find all wireless network interfaces and their status airmon-ng start wlan0 to set in monitor mode, you may have to substitute wlan0 for your own interface name Note: You can use the su command to switch to a root account.

Other related Linux commands: ifconfig to list available network interfaces, my network card is listed as wlan0 ifconfig wlan0 down to stop the specified network card ifconfig wlan0 hw ether change the MAC address of a NIC - can even simulate the MAC of an associated client. Recon Stage airodump-ng This step assumes you've already set your wireless network interface in monitor mode.

Next step is finding available wireless networks, and choosing your target: airodump-ng mon0 - monitors all channels, listing available access points and associated clients within range.

Running airodump-ng on a single channel targeting a specific access point. The retreived key is in hexadecimal, and can be entered directly into a wireless client omitting the ":" separators.

If the number fluctuates a lot, you have weak signal as well. The RXQ value relates to the data stream going from the access point to your computer. Even if this number is above 80, the access point still may not be able to see your computer.

This is the most common reason for fake authentication and packet injection to fail. If that is your case, just sit back and wait until the Data column shows at least ,, and then try step 7 WEP crack. Without authentication and packet injection, this process might take 1,5 - 2 hours. You can start trying WEP crack in step 7 as soon as the Data reaches at least 80,, but our experience is that WEP keys usually get cracked once having somewhere around , initiation vectors.

To crack a WEP key for a wireless access point , we need to gather a lot of initialization vectors IVs , ideally somewhere around , of them. Normal network traffic does not typically generate these initialization vectors very quickly. Theoretically, if you are patient, you can gather sufficient IVs to crack the WEP key by simply passively listening to the network traffic and saving them step 5.

Alternatively, you can use a technique called packet injection to actively speed up the process. Injection involves having the access point resend selected ARP packets they include IVs over and over very rapidly. This allows us to capture a large number of initialization vectors in a short period of time. So, the purpose of this step is to start aireplay-ng in a mode which listens for ARP requests then reinjects them back into the network.

This command will start listening for ARP requests and when it hears one, aireplay-ng will immediately start injecting it. You can generate an ARP request by pinging some other client that is already associated. You can confirm that you are injecting by checking your airodump-ng and aireplay-ng screens. The data packets should be increasing rapidly. The ARP packets and Sent packets should be increasing rapidly as well. Possible problem: Note, if the ARP packets count and the Sent count as well are stuck at zero, then your network interface is likely not associated with your access point.

Or, you can also be too far away from the access point weak signal. Is the source mac associated? Go back to your other window from step 5 and rerun fake authentication. This is not necessary if you went through step 3 though. Once you have captured a large number of initialization vectors, you can use them to determine the WEP key. These commands will calculate WEP key from the captured initialization vectors.

This is what the output looks like:. Now that you know how to break into a WEP-protected network and therefore have discovered the weak link in your wifi network, we would also like to draw your attention to our security tutorials. We have written a few tutorials related to wireless network security. Our wireless security tutorials help you to make your network more secure. This is because Wifite is nothing but a wrapper over all these tools.

Before we even start using Wifite, it is better to update to the latest version. In my case, i already have the latest version.

In this tutorial, we will be targeting a simple Wifi network with WEP encryption. Just using the command wifite -h will give you a list of all the commands. A very tempting option would be -all which tries to attack every network that it finds. We will try it in later articles in this series. However, first lets take a look at all the targets that we have.
