![]() Enter the following command to de authenticate the client in the new terminal window. Now, we have to de authenticate the client against the AP in case they’re already authenticated. ![]() Note: Do not quit the command being executed in the terminal till the 6th step. Here, 09:98:98:98:98:98 is the bssid of the network copied from the above step, -c 1 is the channel number, psk is the file in which the captured traffic would be written and wlan0mon is the network interface that is being monitored. Now, we have to attack a specific network, so in order to do that, we will capture the traffic on that network and will start the capturing of the 4-way handshake. Though there are many other ways as well to crack a wifi password the one with wordlist is the easiest to use and is widely used by the attackers. After getting the encrypted key we try a specific wordlist in order to crack the encrypted password. In Wi-Fi hacking, we capture the 4-way handshake packet and look for the encrypted key in those packets. When a user authenticates through the Access Point the user and the Access Point have to go through a 4-way Handshake in order to complete the authentication process. WPA PSK 2 has a vulnerability which is that the password in the encrypted form is shared by means of a 4-way handshake. When it comes to security nothing is 100% flawless and so as with WPA PSK 2. This WPA 2 uses a stronger encryption algorithm which is known as AES which is very difficult to crack. These days the Wi-Fi networks are more secure than the older days, These days most wireless access points use WPA(Wi-Fi Protection Access) 2 Pre Shared Key in order to secure the network.
