This will disconnect the client from the access point. In the above command, it is optional to give the client mac address it is given by -c The command is aireplay-ng –deauth 10 -a interface In this step, we deauthenticate the connected clients to the Wi-Fi. The above command displays this terminal. In the above command, the path /root/Desktop/hack hack is the name of the file to be saved. w It is used to write the captured data to a specified path in my case it is ‘ /root/Desktop/hack’. c channel is the channel of victim wifi in my case it is 10(see in the previous screenshot for channel number) bssid in my case bssid is indicated with a red mark. In this step, we will add some parameters to airodump-ng.Ĭommand is airodump-ng -c channel –bssid -w wlan0mon. This will be used to know WPA has been captured or not.
This will gather data from the wireless packets in the air. Now, this command captures the packets in the air. We need to use the command airodump-ng wlan0mon, this will display all the access points in your surroundings and also the clients connected to that access points. Note: You should use the interface which is indicated with a red mark. So while using interface in any terminal or command line use wlan0mon. Now this command will enable the monitor mode on the wifi card. The command is as follows:Īirmon-ng start wlan0(interface of wireless card). In this step, you need to enable the monitor mode on the wireless card. For that, you should use airmon-ng check kill. If connected to an external wireless card, it may be wlan1or2.įor some wireless cards, it gives error messages to enable monitor mode on wireless cards. In my case, my wireless adapter is with the name wlan0. We need to know the name of the wireless adapter connected to the computer because the computer has many adapters connected. Aircrack cracks the password.įirst, open the terminal. We can capture handshakes by sending de-authentication packets to clients connected to Wi-Fi. If anyone is not connected to the Wi-Fi, cracking is not possible as we need a WPA handshake.
After that, we should see if anyone is connected to the victim’s Wi-Fi. Wi-Fi transmits signals in the form of packets in the air so we need to capture all the packets in the air so we use airodump to dump all the packets in the air. If your wireless card is not able to do this, you need to get an external wireless card that is capable of monitor/injection mode.Īpart from these tools, you need to have a word list to crack the password from the captured packets.įirst, you need to understand how Wi-Fi works.
To crack Wi-Fi, first, you need a computer with Kali Linux and a wireless card which supports monitor/injection mode.
