Wifi networks have become an integral part of our daily lives, providing us with seamless internet access. However, have you ever wondered how secure your own wifi network is? In this blog post, we will explore the process of cracking wifi passwords using a powerful tool called Aircrack-ng.
What is Aircrack-ng?
Aircrack-ng is a set of tools used to assess the security of wifi networks. It includes tools for packet capturing, password cracking, and network analysis. Aircrack-ng is widely used by security professionals and ethical hackers to test the vulnerability of wifi networks.
Crack Wifi Password
Step 1: Gather the Required Hardware
To crack wifi passwords using Aircrack-ng, you will need a compatible wifi adapter that supports monitor mode. This mode allows the adapter to capture wifi packets without being connected to any network. Make sure to check the compatibility of your wifi adapter with Aircrack-ng before proceeding.
Step 2: Install Aircrack-ng
Aircrack-ng is available for various operating systems including Windows, Linux, and macOS. Visit the official Aircrack-ng website and download the version compatible with your operating system. Follow the installation instructions provided to install Aircrack-ng on your machine.
Step 3: Put Your Wireless Card in Monitor Mode
In order to capture handshake files, you need to put your wireless card in monitor mode. You can do this by running the following command:
sudo airmon-ng start [interface]
Replace [interface] with the name of your wireless interface. You can find the name of your wireless interface by running the command:
sudo iwconfig
Step 3: Capture Packets
Once your wireless card is in monitor mode, you can start capturing Wi-Fi traffic using Airodump-ng. Run the following command:
sudo airodump-ng [interface]
Replace [interface] with the name of your wireless interface.
Step 4: Capture the Handshake
Now that Airodump-ng is running, you need to capture the handshake file. Look for the target network in the list of available networks and note down its BSSID and channel number.
Next, run the following command to capture the handshake file:
sudo airodump-ng -c [channel] --bssid [BSSID] -w [output_file] [interface]
Replace [channel] with the channel number of the target network, [BSSID] with the BSSID of the target network, [output_file] with the name you want to give to the output file, and [interface] with the name of your wireless interface.
Once you have started capturing the handshake file, you need to wait for a device to connect to the target network. This can take some time, so be patient. Once a device connects, Airodump-ng will capture the handshake file and save it to the specified output file.
Step 5: Crack the Password
Once you have captured the handshake, it’s time to crack the wifi password. Use the following command:
sudo aircrack-ng -w [wordlist file] -b [BSSID] [capture file]
Replace [wordlist file] with the path to a wordlist containing possible passwords, [BSSID] with the MAC address of the target network, and [capture file] with the path to the captured handshake file. Aircrack-ng will start the password cracking process using the provided wordlist.
Cracking wifi passwords using Aircrack-ng can be a complex process, but it highlights the importance of securing your own wifi network. It is essential to use strong passwords and encryption protocols to protect your network from unauthorized access. Remember, this guide is for educational purposes only, and it is illegal to crack wifi passwords without proper authorization.
