We will also look at some of the countermeasures you can put in place to protect against such attacks. A wireless network is a network that uses radio waves to link computers and other devices together. The implementation is done at the Layer 1 physical layer of the OSI model. You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc. You will also need to be within the transmission radius of a wireless network access point.
Most devices if the wireless network option is turned on will provide you with a list of available networks. If the network is not password protected, then you just have to click on connect. If it is password protected, then you will need the password to gain access. Since the network is easily accessible to everyone with a wireless network enabled device, most networks are password protected. It was developed for IEEE Its goal was to provide the privacy equivalent to that provided by wired networks.
WEP works by encrypting the data been transmitted over the network to keep it safe from eavesdropping. Open System Authentication OSA — this methods grants access to station authentication requested based on the configured access policy. The station encrypts the challenge with its key then responds. If the encrypted challenge matches the AP value, then access is granted. It is used to encrypt data on It uses temporal keys to encrypt packets. 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. Now, to use this key, firstly start the processes you have killed in Step 1 above using the command I have used below. Finally enter the cracked key without colon as the password of targeted WEP WiFi Network and it will be connected.

It focuses on different area of WiFi security: monitoring, attacking, testing and cracking. Another important requirement is to check if your wireless card is compatible with Aircrack-ng or not. You can either scroll down to read each and every WiFi hacking method or can directly jump to the required section below using these links:.
Now follow these below steps:. And, allowed size of password is 64 characters. I hate to tell you this but yes, doing it on your own can take forever. The tool is fluxion. Instead of doing this, it performs a little bit of phishing where the already connected user is asked to enter password of WiFi network again for security reason and when the user enter the password, first the handshake is checked with the earlier captured handshake of the device, if handshake is correct that means the password entered by user is correct.
Once it is successful, Fluxion returns the key required to authenticate the network. Read Complete Writte. 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.
Enter the following command in terminal: It will show you the output like this: Using the above methods, you should have known the encryption-type of targeted WiFi network which you want to hack. It will show you what network interface are you using.
