Now we will use the Aircrack-ng suite of tools against a WPA2 wireless network. The process involves identifying our target network, capturing the four-way handshake, and then utilizing a wordlist to brute-force the passcode that, in combination with the wireless network's SSID, is the pre-shared key. By cracking the passcode, we will then be able to authenticate to the target wireless network:
- Ensure that you have your wireless network card inserted and that it is working properly. For this, enter the following command into the command line:
# iwconfig
The command should output something similar to the following screenshot. If you do not see the wireless interface, ensure that it is properly configured:
