WPA cracking with Aircrack-ng

In the previous section, we have mentioned that to crack a WPA key, we must first capture the four frames related to a WPA handshake between the target AP and a client. To do so, we could passively wait for a client to authenticate successfully, completing the handshake, and capture the relative frames. In some cases, we will need to wait a little longer, so we could accelerate the process deauthenticating an already connected client, inducing it to re-authenticate with the AP (the deauthentication attack).

We begin by putting, as usual, our wireless interface in monitor mode with the airmon-ng start wlan0 command and then run airodump-ng, using the BSSID and the channel of our target AP as parameters:

airodump-ng --channel 1 --bssid 08:7A:4C:83:0C:E0 --write wpa_crack mon0
