Essentially, Wi-Fi hacking is cracking the security protocols in a wireless network, granting complete access for the hacker to view, store, download, or abuse the wireless network. With all the information gathered from your compromised Wi-Fi, hackers can use your information for their own personal requirements.
This technique functions in the following way:
The following steps will help you crack a Wi-Fi password using kali.
Use keyboard shortcut Ctrl+alt+t or type terminal in the search box to open a terminal window in Kali.
You are required to know first the name of your Wi-Fi adaptor before putting your Wi-Fi into monitor mode and for that type in the following command in the terminal.
I am going to perform all the following commands on this adaptor as you can see, I have a single Wi-Fi adaptor(wlan0).
Now to put this adaptor into monitor mode type the subsequent command in the terminal.
While your Wi-Fi is in monitor mode, notice that you can’t use your internet. And my adeptor name is changed from wlan0 to wlan0mon.
We are required to kill background processes, before we start monitoring Wi-Fi signals. So that they will not be able to interrupt while we are working in monitoring mode, for that type following command in the terminal window.
You can start monitoring the Wi-Fi signals near you, after putting your Wi-Fi into monitor mode.
We are going to use airodump-ng command to start monitoring Wi-Fi signals. Just type the subsequent command in the terminal.
On the upper part of the screen, all the visible access points (APs) are shown and all the clients which are connected to the APs are listed below.
If you came across your target in the list of visible APs and at least one client connected to that AP, we can go further else you require to wait for somebody to get connected to that AP first.
Now open up a new terminal window (don’t close the present window) because we required to copy bssid and channel from the current window.
Type the following command in the terminal window.
In order to capture the hand-shake which contains the encrypted password, we need to disconnect the connected clients from the AP. For that open new terminal window and type the following command.
This command will send 10 de-authentication packets to the AP which will cause the clients to disconnect from the AP.
And when they will try to reconnect to the AP we will get the file containing the encrypted password. As you can see in the following image we got a message saying “WPA Handshake: BSSID of target” this message means our attack is successful, and we are able to capture the handshake file.
We can find a capture file on the location we specified in the 4th step, in my case it’s root/WPfile-01.cap.
Now, to decrypt the password present in our file WPfile-01.cap, we need to run the following command against this file using a password list, in my case, I am using a custom password list named PasswordList.txt.
