Anyone in the WiFi range can connect his device to the network without any password in enjoy free internet.

However, these networks are rarely available and also risky. It will show you what network interface are you using. In my system, I have only one network interface card wlan0 , which is my wireless interface card. Create a network interface which runs in monitor mode. To do this enter command airmon-ng start wlan0.

Make sure to replace wlan0 in command with the interface name that your card have. Here, mon0 has been created. Now, you might or might not get the warning appearing in the below screenshot which tells other processes using the network which can create the problem.

So, you can kill them using the syntax: kill PID if you know those processes are not important for you at the moment. It can take time to all the available WiFi networks in range. First enter the command airplay-ng -1 0 -a FB:A9:B1 mon0 to perform fake authentication -1 in command to the network.

Hit enter and the command will start doing attack to WEP WiFi Access point and you can see the Data value increasing at enormously fast rate. In below screenshot the bell Once you have enough data in the file bell It will test all the data values available in key file and automatically show you the key it found by testing data in file.

It will be in hex format but work just fine. Once they are forced to log out, they will automatically log back in. We need to capture that. After signing in, the WPA handshake will appear on the right in the first window. This means that we have captured the encrypted password so we can cancel the capturing.

We need a dictionary, which is actually just a text file where the passwords we want to try are listed. The program takes words from the dictionary, encrypting it and comparing it with the encrypted password we have captured. If it matches, we get the original unencrypted password. If the password is in this dictionary, it will be revealed.

It was password no. We tested the passwords at about a thousand attempts per second. Obviously, we can not prevent someone from capturing our encrypted password while we sign in to the WIFI network.

However, we can make it more difficult for a potential attacker by setting up a strong password that should include at least the following:. So we can use 62 characters for each position. You should also have on mind that when someone gets access to your network via WIFI, it can open new ways to get access to the router through a dictionary attack. I am particularly interested in implementing network solutions and network security for corporate clients.
