The Basics of Wireless WPA2 Hacking with Kali Linux

I'm going to be using Windows 10 with Oracle VM virtual machine running Kali Linux 2020 VM Box distribution.

You will need a wireless adapter card that can enabled monitor mode to gather any information on any surrounding networks.

Enabling Monitor Mode

Once you've logged in your virtual machine running kali, open a new shell and type

Code

iwconfig

I'm using an Alfa AWUS036AV, this adapter can enable monitor mode as well as packet injection but currently the adapter is in managed mode, please note the name of the adapter wlan0.

I'm going to turn my adapter off, turn on monitor mode and turn my adapter back on with the following commands,

Code

ifconfig wlan0 down

Code

iwconfig wlan0 mode monitor

Code

ifconfig wlan0 up

You can alternatively use Aircrack commands to list adapters and enable monitor mode. Aircrack is installed as factory with kali. The reason i don't use them is because the Alfa AWUS036AV doesn't have interface monitoring and will not work with this step of Aircrack however works perfectly fine with the previous steps.

The following commands to execute using Aircrack are,

This will list all available devices that can enable monitor mode.

Code

airmon-ng

This will start monitor mode for device wlan0.

Code

airmon-ng start wlan0

Scanning the Surrounding Area

Now you have enabled monitor mode on your device with either of these steps it's time to start scanning the surrounding area.

The following command will scan all surrounding networks.

Code

airodump-ng wlan0

After a few minutes many networks will start to relay information back to your shell like above, it's important to note everything up until this point is perfectly legal but any further attacks on networks you don't own or don't have permission to be on is not allowed.

Targeting Our Network

From here you need to run,

Code

airodump-ng --bssid [BSSID NUMBER] -c 11 -w capture wlan0

This command will open a similar interface to before but specifically capturing information sent and received by the bssid provided.

You will need to monitor this network until you log a wpa handshake, a 4 way authentication process between two devices that will be saved as a packet capture file .cap, from here convert your .cap file with hashcat cap2hccapx converter, then you can attempt to crack your new .hccapx file.
