Run iwconfig. You should now see a new monitor mode interface listed likely mon0 or wlan0mon. Start listening to For the purposes of this demo, we will choose to crack the password of my network, 'hackme'. You don't have to know anything about what that means, but you do have to capture one of these handshakes in order to crack the network password. These handshakes occur whenever a device connects to the network, for instance, when your neighbor returns home from work.
We capture this handshake by directing airmon-ng to monitor traffic on the target network using the channel and bssid values discovered from the previous command.
Now we wait Once you've captured a handshake, you should see something like [ WPA handshake: bc:d3:c9:ef:d at the top right of the screen, just right of the current time. If you are feeling impatient, and are comfortable using an active attack, you can force devices connected to the target network to reconnect, be sending malicious deauthentication packets at them.
This often results in the capture of a 4-way handshake. See the deauth attack section below for info on this. Once you've captured a handshake, press ctrl-c to quit airodump-ng. You should see a. We will use this capture file to crack the network password. I like to rename this file to reflect the network name we are trying to crack:.
The final step is to crack the password using the captured handshake. If you have access to a GPU, I highly recommend using hashcat for password cracking. I've created a simple tool that makes hashcat super easy to use called naive-hashcat.
You can also try your hand at CPU cracking with Aircrack-ng. Note that both attack methods below assume a relatively weak user generated password. If you are attempting to crack one of these passwords, I recommend using the Probable-Wordlists WPA-length dictionary files. Before we can crack the password using naive-hashcat, we need to convert our. 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. Before moving directly to the methods to hack WiFi networks lets first see what type of security and authentication methods are implemented in WiFi networks. If somebody is already connected to the network, you can check in his network properties to see what encryption-type is being using by the targeted WiFi network.
But if you want to know encryption-type of WiFi network which is not connected to any device in your reach, you need Ubuntu operating system to do this. In Ubuntu, you can use nmcli command in terminal which is command-line client for NetworkManager. It will show you security types of nearby Wi-Fi access points. Enter the following command in terminal:. Using the above methods, you should have known the encryption-type of targeted WiFi network which you want to hack.
My methods require KALI Linux which is especially designed Linux distrbution for penetration testing and ethical hacking. You can download it for free from its official site. You will also need Aircrack-ng which is a security suite to assess WiFi network security. 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.
