Please note that hacking into someone else's Wi-Fi network without permission is illegal and unethical.
The following information is for educational purposes only and should not be used for unauthorized access.
Kappa

Research the target Wi-Fi network
 
To successfully hack a Wi-Fi network, you first need to gather information about the network.
This process, known as reconnaissance or footprinting, will help you identify the type of encryption used, the router model,
and any other relevant information that may be helpful during the hacking process.


Identify the network name (SSID) and encryption type: Scan for available Wi-Fi networks on your device (e.g., smartphone, laptop, or tablet) and locate the target network's name (SSID). Pay attention to the type of encryption being used by the network, which is typically displayed alongside the network name. Common encryption types include WEP, WPA, and WPA2, with WPA2 being the most secure and WEP the least secure.

Determine the router model: The router model can sometimes be identified by looking at the network's properties on your device or by physically examining the router itself if you have access to it. Router models often have a label with the model name and number. Additionally, some router models broadcast their information within the Wi-Fi network's SSID. For example, a network named "NETGEAR_1234" likely indicates that the router is a Netgear model.

Research the router's default settings: Once you have identified the router model, search online for its documentation, which can usually be found on the manufacturer's website. The documentation may provide valuable information about default settings, such as the default IP address, login credentials (username and password), and any known vulnerabilities. Default settings can sometimes be exploited to gain unauthorized access to the network.

Monitor the network's signal strength and connected devices: Analyze the target network's signal strength, which can be done using built-in tools on your device or third-party applications. Stronger signals usually indicate that you are closer to the router, which can be helpful when attempting to capture a handshake. Additionally, monitoring the network for connected devices can provide information on the best times to perform an attack when the network is less active or when a new device connects.

Check for known vulnerabilities: Search online for known vulnerabilities associated with the target router model or the type of encryption being used. Websites like Exploit Database (https://www.exploit-db.com/) and the National Vulnerability Database (https://nvd.nist.gov/) are valuable resources for discovering known vulnerabilities. If any vulnerabilities are found, you may be able to exploit them to gain unauthorized access to the network.
By thoroughly researching the target Wi-Fi network, you can gather the necessary information to choose the most appropriate hacking method and tools, increasing your chances of success. However, always remember that hacking into someone else's Wi-Fi network without permission is illegal and unethical. Use this information for educational purposes only and always obtain permission before testing the security of a Wi-Fi network that does not belong to you.
 
Gather the necessary tools
  1. Wi-Fi Hacking Suite: A Wi-Fi hacking suite is a collection of tools that are designed to work together to perform various tasks related to Wi-Fi hacking. Two popular Wi-Fi hacking suites are Aircrack-ng and Kali Linux:
    a. Aircrack-ng: Aircrack-ng is a suite of tools for auditing wireless networks. It focuses on key tasks such as monitoring, attacking, testing, and cracking Wi-Fi passwords. You can download Aircrack-ng from its official website (https://www.aircrack-ng.org/) and install it on your computer. Follow the installation instructions provided on the website for your specific operating system.
    b. Kali Linux: Kali Linux is a Linux-based operating system specifically designed for penetration testing and security auditing. It comes pre-installed with a wide range of tools, including Wi-Fi hacking tools, making it an excellent choice for aspiring ethical hackers. You can download Kali Linux from its official website (https://www.kali.org/) and install it on your computer as the primary operating system, on a virtual machine, or as a bootable USB drive.
  2. Compatible Wi-Fi Adapter: To hack a Wi-Fi network, you will need a Wi-Fi adapter that supports monitor mode and packet injection. Monitor mode allows your adapter to capture packets from the target network without connecting to it, while packet injection is necessary for certain types of attacks. Research and purchase a compatible Wi-Fi adapter, ensuring that it is supported by the Wi-Fi hacking suite you have chosen (Aircrack-ng or Kali Linux). Some popular options include the Alfa AWUS036NHA and the TP-Link TL-WN722N.
  3. Password Lists (for Dictionary Attacks): A dictionary attack involves trying a list of known passwords to crack the Wi-Fi password. To perform a dictionary attack, you will need a password list or a wordlist. Several online resources offer precompiled password lists, such as the RockYou password list (https://github.com/brannondorsey/naive-h...ockyou.txt) or the SecLists repository (https://github.com/danielmiessler/SecLists). Alternatively, you can create your own password list based on the target's information or use a wordlist generator like Crunch (https://github.com/crunchsec/crunch).
  4. Additional Tools and Utilities: Depending on your chosen method of attack and the specific vulnerabilities of the target network, you may need additional tools and utilities. Some examples include Wireshark (https://www.wireshark.org/) for network analysis, Reaver (https://code.google.com/archive/p/reaver-wps/) for WPS-based attacks, and Hashcat (https://hashcat.net/hashcat/) for advanced password cracking. Research these tools and download them as needed, ensuring they are compatible with your chosen Wi-Fi hacking suite.
 

Set your Wi-Fi adapter to monitor mode

 
Monitor mode, also known as "RFMON" (Radio Frequency MONitor) mode, is a setting that allows your Wi-Fi adapter to capture raw 802.11 wireless packets from the air without connecting to a specific network. This mode is essential for Wi-Fi hacking, as it enables you to capture the target network's handshake and other useful information.
Here's a detailed explanation of how to set your Wi-Fi adapter to monitor mode:

Check your Wi-Fi adapter compatibility: Not all Wi-Fi adapters support monitor mode. To determine if your adapter is compatible, search the adapter's documentation or look up its chipset online. Compatible chipsets include Atheros, Broadcom, and Ralink, among others.
 
Install the necessary drivers: Ensure that you have the correct drivers installed for your Wi-Fi adapter. In some cases, you may need to install additional drivers or patches to enable monitor mode. You can usually find these drivers on the adapter manufacturer's website or the chipset manufacturer's website.
 
Open the terminal or command prompt: To enable monitor mode, you will need to interact with your Wi-Fi adapter through the terminal on Linux or macOS or the command prompt on Windows.
 
Identify your Wi-Fi adapter: In the terminal or command prompt, enter the following command:
 
For Linux or macOS:
 
Code:
sudo ifconfig

For Windows:
 
Code:
ipconfig /all


 
This command will display a list of network interfaces on your computer. Identify the name of your Wi-Fi adapter (e.g., wlan0, en0, or Wi-Fi).
Enable monitor mode: To enable monitor mode, you can use the following commands based on your operating system.
 
 For Linux:

a. Turn off your Wi-Fi adapter:
Code:
sudo ifconfig YourInterface down

b. Enable monitor mode:
Code:
sudo iwconfig YourInterface mode monitor
c. Turn on your Wi-Fi adapter:
Code:
sudo ifconfig YourInterface up
 
For Windows:
Windows does not natively support monitor mode, so you will need to use third-party tools, such as Npcap (https://nmap.org/npcap/) or Acrylic Wi-Fi (https://www.acrylicwifi.com/). Follow the instructions provided by these tools to enable monitor mode on your Wi-Fi adapter.
Once your Wi-Fi adapter is set to monitor mode, you will be able to capture packets and information from the target network without connecting to it. This is a crucial step in the Wi-Fi hacking process, allowing you to capture the target network's handshake, which is needed to crack the password.


Capture the target network's handshake
 
A "handshake" is the process that occurs when a device connects to a Wi-Fi network. It involves the exchange of cryptographic data between the device and the router to establish a secure connection. Capturing this handshake is crucial for cracking the Wi-Fi password, as it contains the information needed to perform a password attack.

For this detailed explanation, we'll use Aircrack-ng as our hacking tool, but the process is similar for other tools, such as Kali Linux. Aircrack-ng is a suite of tools for 802.11 wireless network auditing.
Install Aircrack-ng: First, download and install Aircrack-ng from the official website (https://www.aircrack-ng.org/). Make sure your operating system is compatible with the software, and follow the installation instructions provided on the website.
Open the terminal or command prompt: To use Aircrack-ng, you will need to interact with it through the terminal on Linux or macOS, or the command prompt on Windows.
Identify your Wi-Fi adapter: In the terminal or command prompt, enter the following command:
For Linux or macOS:
 
Code:
sudo airmon-ng
For Windows:
 
Code:
airmon-ng
 
This command will display a list of Wi-Fi interfaces on your computer. Take note of the name of the interface you want to use (e.g., wlan0, en0, or Wi-Fi).
Enable monitor mode: To capture the handshake, your Wi-Fi adapter must be set to monitor mode. Enter the following command in the terminal or command prompt, replacing "YourInterface" with the name of your Wi-Fi interface:
For Linux or macOS:
 
Code:
sudo airmon-ng start YourInterface
For Windows:
 
Code:
airmon-ng start YourInterface
 
After running this command, your Wi-Fi adapter will be set to monitor mode, and a new interface will be created (e.g., mon0, wlan0mon, or YourInterfaceMon). Note the name of the new interface.
Scan for target networks: Use Airodump-ng to scan for nearby Wi-Fi networks by entering the following command, replacing "YourMonitorInterface" with the name of the monitor mode interface:
For Linux or macOS:
 
Code:
sudo airodump-ng YourMonitorInterface
 
For Windows:
 
Code:
airodump-ng YourMonitorInterface
 
A list of nearby Wi-Fi networks will be displayed, along with their BSSID (router's MAC address), ESSID (network name), and other information. Identify the target network and note its BSSID and channel number.
Capture the handshake: To capture the handshake, use Airodump-ng again, but this time, specify the target network's BSSID and channel number. Replace "YourMonitorInterface," "TargetBSSID," and "TargetChannel" with the appropriate values. Also, replace "YourOutputFile" with a name for the output file where the handshake data will be saved:
For Linux or macOS:
 
Code:
sudo airodump-ng -c TargetChannel --bssid TargetBSSID -w YourOutputFile YourMonitorInterface
 
For Windows:
 
Code:
airodump-ng -c TargetChannel --bssid TargetBSSID -w YourOutputFile YourMonitorInterface
 
Airodump-ng will now monitor the target network and capture the handshake when a device connects or reconnects. This may take some time, as you must wait for a device to connect to the Wi-Fi network.

 
Launch a dictionary or brute-force attack
 
Once you have captured the target network's handshake (as explained in the previous detailed explanation), you can use it to attempt to crack the Wi-Fi password. There are two main methods for doing this: a dictionary attack and a brute-force attack.
Dictionary Attack: A dictionary attack involves trying a list of known passwords, often obtained from data breaches, open-source password lists, or created based on common words and phrases. The attacker's success depends on the target password being included in the dictionary file.
To perform a dictionary attack using Aircrack-ng, follow these steps:
 Obtain a dictionary file: Download or create a dictionary file containing potential passwords. Many dictionary files are available online, such as the RockYou wordlist (https://github.com/brannondorsey/naive-h...ockyou.txt).
 Launch the dictionary attack: Run the following command in the terminal or command prompt, replacing "YourHandshakeFile" with the path to the captured handshake file (in .cap format) and "YourDictionaryFile" with the path to your dictionary file:
 
Code:
aircrack-ng -w YourDictionaryFile YourHandshakeFile.cap
 
Analyze the results: Aircrack-ng will attempt to crack the password using the dictionary file. If the password is found, it will be displayed in the terminal or command prompt. If the attack is unsuccessful, you may need to try a different dictionary file or switch to a brute-force attack.
Brute-Force Attack: A brute-force attack tries different combinations of characters until the correct password is found. This method can be time-consuming, as it depends on the complexity of the password and the speed of your computer.
To perform a brute-force attack using Aircrack-ng, follow these steps:
Define the character set and password length: Determine the range of characters to use in the attack (e.g., lowercase letters, uppercase letters, numbers, special characters) and the minimum and maximum password lengths.
Generate a custom mask or rule file: Use a tool like Crunch (https://sourceforge.net/projects/crunch-wordlist/) to generate a custom mask or rule file based on your character set and password length. For example, to create a rule file for passwords between 8 and 12 characters long, using lowercase letters and numbers, run the following command:
  
Code:
crunch 8 12 abcdefghijklmnopqrstuvwxyz0123456789 -o YourRuleFile.txt
 
Launch the brute-force attack: Run the following command in the terminal or command prompt, replacing "YourHandshakeFile" with the path to the captured handshake file (in .cap format) and "YourRuleFile" with the path to your rule file:
 
Code:
aircrack-ng -w YourRuleFile.txt YourHandshakeFile.cap
 
Analyze the results: Aircrack-ng will attempt to crack the password using the generated rule file. This process may take a significant amount of time, depending on the complexity of the password and the speed of your computer. If the password is found, it will be displayed in the terminal or command prompt. If the attack is unsuccessful, you may need to try a different character set, password length, or switch to a dictionary attack.
