Handshake capture with Airodump-ng and Aireplay-ng

You can easily view the Handshake with the help of Airodump and Airplay programs pre-installed on Kali Linux.

The process is relatively easy. It will be done with Airodump through which we will monitor all her wireless access points s, to deauthenticate, and then we'll use Airodump-ng and Aireplay.

Your computer has many network adapters, so to scan one, you need to know its name. Here are the basic adapters you need to know:

  • lo - loopback. (you do not need it at the moment)
  • eth0 - ethernet (wired connection)
  • wlan0 - Wireless connection (what we really need)

Now, to see the configuration of your wireless adapter, type “iwconfigAt the same terminal.

If wlan0 does not appear while you have one installed Wi-Fi, then you are most likely using Kali as a virtual machine. Unfortunately virtual machines cannot use internal wireless network cards and you will have to use an external card such as Alfa or Tp-Link.

Now the first step is to create a virtual interface for wlan0 that will monitor all packages.

Mandate: airmon-ng start wlan0

A new interface i.e. Wlan0mon will be created in monitoring mode.

Now, we will use airodump-ng to capture the packets. This tool collects the from wireless packages that are in range of our Wi-Fi. So you find the name of the Wi-Fi you want to check.

Mandate: airodump -ng wlan0mon

The next step is to save the downloaded packages to a file using the same airodump tool by typing the following command:

Mandate:

Now copy the bssid address of your target network (from airodump-ng ng) and launch a deauthentication attack by typing the aireplay-ng command as shown below:

Mandate:

In case you have problems with the monitoring function from one channel to another or with the beacon, then fix wlan0mon on a specific channel by typing:

Mandate:

number > with the channel in which your target AP is located.

Once a client is disconnected, the handshake will appear in the previous terminal as shown below:

You can even confirm this by typing the following command:
