Remember, hacking into networks without permission is illegal and unethical. This guide is for educational purposes to help you understand and secure your networks.
## Introduction to WiFi Hacking
WiFi hacking involves exploiting vulnerabilities in wireless networks to gain unauthorized access. It encompasses various methods, each with specific tools and techniques. Here, we explore several popular tools and attacks:
1. **Wifite**: An automated tool for testing the security of WiFi networks.
2. **Fern WiFi Cracker**: A GUI-based tool for wireless network security testing.
3. **Reaver**: A tool for brute-forcing WPS (WiFi Protected Setup) pins.
4. **WiFi Jammer**: A tool for jamming WiFi networks.
5. **WiFiDoser**: Advanced WiFi jamming tool.
6. **Fake AP Creation**: Technique for creating multiple fake access points.
7. **WiFi Admin Panel Attack**: Exploiting vulnerabilities in the router’s admin panel.
8. **WiFi Multi Tool Attack**: Combining multiple attack vectors on a single network.
## Wifite: Automated Wireless Attack Tool
### Wifite WPS Attack
Wifite automates WiFi hacking, targeting WPS, WPA, and WPA2 encryption. The WPS attack exploits the WPS protocol, which is designed to simplify connecting devices to a WiFi network.
1. **Launching Wifite**:
- Open your terminal in Kali Linux.
- Run Wifite: `sudo wifite`.
- Wifite scans for available networks.
2. **Executing WPS Attack**:
- Select a target with WPS enabled.
- Wifite uses Reaver to brute-force the WPS pin.
- If successful, it reveals the network’s WPA/WPA2 passphrase.
### Wifite WPA Attack
WPA (WiFi Protected Access) and WPA2 are common security protocols. Wifite’s WPA attack involves capturing the handshake and performing a dictionary attack.
1. **Capturing the Handshake**:
- Select a target with WPA/WPA2 security.
- Wifite deauthenticates a client to capture the handshake.
2. **Performing Dictionary Attack**:
- Once the handshake is captured, Wifite uses a dictionary file to crack the password.
- Success depends on the strength of the password and the quality of the dictionary file.
### Wifite PMKID Attack
The PMKID attack targets networks with WPA/WPA2 security by capturing a PMKID from the network.
1. **Capturing the PMKID**:
- Select a target network.
- Wifite captures the PMKID from the AP (Access Point).
2. **Cracking the PMKID**:
- Use a tool like Hashcat to crack the captured PMKID.
- This method does not require deauthenticating a client, making it stealthier.
## Using Wifite on Kali Linux
Kali Linux is the go-to operating system for penetration testing and ethical hacking. Installing and using Wifite on Kali Linux is straightforward.
1. **Installation**:
- Kali Linux comes pre-installed with Wifite. If not, install it using: `sudo apt-get install wifite`.
2. **Running Wifite**:
- Simply execute `sudo wifite` in the terminal to start the tool.
## Fern WiFi Cracker
Fern WiFi Cracker is a GUI-based tool for wireless security auditing. It supports WEP, WPA, and WPS attacks.
1. **Launching Fern WiFi Cracker**:
- Open Fern WiFi Cracker from the applications menu.
2. **Performing an Attack**:
- Select your wireless interface.
- Scan for available networks.
- Choose a target network and select the type of attack (WEP, WPA, WPS).
## Reaver: Brute-Forcing WPS Pins
Reaver is designed to brute-force WPS pins, providing access to WPA/WPA2 networks.
1. **Installation**:
- Install Reaver: `sudo apt-get install reaver`.
2. **Using Reaver**:
- Start Reaver: `sudo reaver -i <interface> -b <BSSID> -vv`.
- Reaver attempts to brute-force the WPS pin. If successful, it reveals the WPA/WPA2 passphrase.
## WiFi Jammer: Disrupting Network Connectivity
A WiFi jammer disrupts the connectivity of devices on a network by sending deauthentication packets.
1. **Installing WiFi Jammer**:
- Install the necessary tools: `sudo apt-get install aircrack-ng`.
2. **Jamming the Network**:
- Identify the target network and its clients.
- Use `aireplay-ng` to send deauthentication packets: `sudo aireplay-ng -0 0 -a <AP_MAC> -c <Client_MAC> <interface>`.
## Advanced WiFi Jamming with WiFiDoser
WiFiDoser is an advanced tool for jamming WiFi networks, offering more features and control.
1. **Installing WiFiDoser**:
- Download WiFiDoser from the official repository.
- Follow the installation instructions.
2. **Using WiFiDoser**:
- Configure the target network and clients.
- Execute the jamming operation to disrupt connectivity.
## Creating Multiple Fake Access Points
Creating fake access points (APs) can be used to conduct phishing attacks or gather network information.
1. **Using `airbase-ng`**:
- Install `airbase-ng`: `sudo apt-get install aircrack-ng`.
- Create a fake AP: `sudo airbase-ng -e <SSID> -c <channel> <interface>`.
2. **Configuring the Fake AP**:
- Use additional tools like `dnsmasq` for DHCP services.
- Set up a web server to serve phishing pages if needed.
## WiFi Admin Panel Attack
Exploiting vulnerabilities in the router’s admin panel can grant control over the network.
1. **Finding the Admin Panel**:
- Identify the router’s IP address (usually `192.168.1.1` or `192.168.0.1`).
2. **Launching the Attack**:
- Use default credentials or brute-force the login.
- If successful, gain access to the router’s settings and modify configurations.
## WiFi Multi Tool Attack on a Single Network
Combining multiple attack vectors on a single network can enhance the chances of success.
1. **Reconnaissance**:
- Use tools like `Kismet` to gather detailed information about the target network.
2. **Executing Multiple Attacks**:
- Perform a WPS attack with Wifite.
- Simultaneously use WiFi Jammer to disrupt network connectivity.
- Attempt a PMKID attack for an additional vector.
3. **Post-Exploitation**:
- Once access is gained, maintain persistence by modifying the router’s firmware or settings.
## Conclusion
WiFi hacking is a critical aspect of cybersecurity, highlighting the importance of securing wireless networks. This guide covered various tools and techniques for ethical hacking, emphasizing the need for responsible use. By understanding these methods, you can better protect your networks and contribute to a safer digital environment. Always remember, unauthorized hacking is illegal and punishable by law. Use your skills for good and help create a secure cyberspace.
