In the realm of the digital era, network security and ethical hacking have been an important field and have drawn a lot of attention lately. A very significant tool called Aircrack-ng allows the security experts and enthusiasts to analyze the vulnerabilities in a wireless network. Users can explore and secure their own Wi-Fi networks with the help of Aircrack-ng’s capabilities within the Termux environment. It is one of the essential tools for those who are interested in network security.
What is Termux?
Termux is a special software present for mobile users. As there are terminals present in every operating system, the Termux is similar to that. It is an Android terminal emulator and Linux environment application that gives you access to a command-line interface on your face. This acts as the terminal in Android mobile. The cyber experts tend to prefer this because it allows users to access and use a variety of Linux utilities and packages. While using Termux, you can take the benefit of Aircrack-ng’s potential on your Android device, which allows you to perform network assessments wherever you are.
How Can You Install Termux?
For installing the Aircrack-ng, you need to first install the Termux on your device. To install Termux on your Android device, follow the below given steps:
- Open the Google Play Store on your Android device.
- Search for “Termux” in the search bar.
- Select the official Termux app from the search results.
- Tap on the “Install” button and wait for the installation to complete.
- Once installed, launch the Termux app.
What is Aircrack-ng?
Aircrack-ng is a famous software used for Wi-Fi network security. There are many tools included in the software. It is also known as a suite of tools that help in Wi-Fi security purposes. This software mainly applies to Linux distribution, which means different Linux distributions can run the Aircrack-ng. Aircrack-ng is used for the purpose of monitoring Wi-Fi. It also helps to export the data to the text file for monitoring and testing purposes. It is used to know whether the Wi-Fi cards are running appropriately or not.
Features of Aircrack-ng
- Though, the Aircrack-ng software is suitable for every operating system such as Windows, Linux, etc., but it is mainly used in Linux distributions.
- These tools can show up different Wi-Fi availability in the Monitor mode.
- The Aircrack-ng tool uses encrypted packets to monitor the Wi-Fi networks. This makes it safe to use.
- The Aircrack-ng tool can communicate with the access point during operations.
- The Aircrack-ng software defends the Access point, due to which it takes a smaller amount of time than other applications.
How To Install Aircrack-ng?
As soon as Termux is operational, we can now install Aircrack-ng. Below, we have discussed the steps to install Aircrack-ng:
- To begin with, the users shall open the Termux software and execute the following command. This command will help to prepare the repository that is required for the installation process of Aircrack-ng. It may take some time to complete, you might wait till the process is completed. apt install root-repo
- As soon as the repository is ready for the installation process, next you execute the following command. This will help to install the Aircrack-ng in the Termux. Again, this may take some time to process and you need to wait patiently for the process to complete. apt install aircrack-ng -y
- After you installed Aircrack-ng successfully, you need to run the following command. This is necessary to help to save the changes and the installation process. This command can be treated as one of the closing commands for the installation process. apt install iw
- So, we are done with the installation process and it is directed to execute the following command, this will provide the same network speed. This indicates that the Aircrack-ng is installed successfully and now it can read the network speed.
Hence, we have successfully installed the Aircrack-ng in Termux.
How To Use Aircrack-ng?
Just as you successfully installed Aircrack-ng on Termux, let us examine some of the common use scenarios and commands.
- View wireless networks available: Execute the following command to get a list of nearby Wi-Fi networks. The BSSIDs (Basic Service Set Identifiers) of the wireless networks in the area, with their channels and signal strengths, will be shown by this command- airodump-ng wlan0
- Capture packets: The following command assists in taking packets from a particular Wi-Fi network. For this, change “BSSID” to the MAC address of the target network, “channel” to the network’s operational channel, and “output_file” to the desired name for the captured packet file. This command will start packet capture and save the captured packets to the output file you specify. airodump-ng –bssid <BSSID> –channel
- Crack WEP encryption: You can intrude into a WEP- encrypted network by using Aircrack-ng, to collect enough packets from it. Change “BSSID” to the MAC address of the target network, “wordlist” to the location of a wordlist file containing significant passwords, and “capture_file” to the file having the captured packets. Aircrack-ng will help to examine the packets it has intercepted. Run the following command- aircrack-ng -b <BSSID> -w <wordlist>
- Crack WPA/WPA2-PSK encryption: Make use of dictionary attacks to break networks secured with WPA/WPA2-PSK encryption. Change “wordlist” to the location of a wordlist file containing potential passwords, “BSSID” to the target network’s MAC address, and “capture_file” to the file containing the packets that were captured. The wordlist will be iterated through by Aircrack-ng in an attempt to identify the proper network passphrase. aircrack-ng -w <wordlist> -b <BSSID>
Conclusion
If we use Aircrack-ng in a responsible way, it acts as an excellent tool for evaluating the security of wireless networks. As instructed, it is a very easy process to set up Aircrack-ng on your device in the Termux environment. Always remember that you do not disrespect others’ security and privacy while using this tool . Instead, you can create a safer online environment by keeping yourself informed about the most recent network security developments. Before we jump into analyzing or testing the security of any wireless networks, always make sure you have the required authorization and permission.
