Infiltrating Wi-Fi Networks: Software and Techniques Without a Router

Fern WiFi Cracker

Fern WiFi Cracker is a network security tool designed with a user-friendly graphical interface, making it easy for users, especially beginners, to conduct security audits on Wi-Fi networks. With its intuitive interface, Fern WiFi Cracker allows users to perform a series of tests and attacks against Wi-Fi networks without requiring in-depth knowledge of the command line.

Fern WiFi Cracker offers a variety of key features that help users test the security of Wi-Fi networks, including:

• WEP Cracking: Supports attacks on networks with WEP encryption.
• WPA/WPA2 Cracking: Uses brute-force attacks to crack WPA/WPA2 network passwords.
• WPS Attack: Attacking routers with WPS features enabled.
• MAC Address Changer: Change the MAC address of the Wi-Fi adapter to hide the identity of the device.
• Session Hijacking: Taking over network sessions to access sensitive information.
• Network Scanner: Scans the network to find connected devices.

Example of Steps to Hack Wi-Fi with Fern WiFi Cracker

Here are the basic steps to use Fern WiFi Cracker:

1. To install Fern WiFi Cracker on Linux (for example, Debian-based distributions such as Ubuntu), open a terminal and run the following command:

sudo apt-get update
sudo apt-get install fern-wifi-cracker

2. Open Fern WiFi Cracker by typing the following command in the terminal:

3. The graphical interface of Fern WiFi Cracker will open.
4. Select the Wi-Fi adapter you want to use from the dropdown list. Make sure the adapter is in monitor mode.
5. Click the Scan for Access Points button to scan for available Wi-Fi networks.
6. Fern WiFi Cracker will display a list of detected networks, complete with information such as SSID, BSSID, channel, and encryption used.
7. Select the target network from the list of detected networks.
8. If the network uses WEP encryption, select the WEP option and if it uses WPA/WPA2, select the WPA option.
9. For WEP networks:
   • Click the Attack button under the WEP section to initiate the attack. Fern WiFi Cracker will collect data packets and try to decrypt WEP keys.
10. For WPA/WPA2 networks:Click the Attack button under the WPA section to start a brute-force attack. You need to provide a wordlist that contains a list of possible passwords.
11. Fern WiFi Cracker will try password combinations from a wordlist until it finds the correct one.
12. You can also use additional features like MAC Address Changer to change your MAC address or Network Scanner to scan for network-connected devices.

Example Use Cases

Suppose you want to test the security of your home Wi-Fi network that uses WPA2 encryption. With Fern WiFi Cracker, you can perform the following steps:

1. Open Fern WiFi Cracker and select your Wi-Fi adapter.
2. Click Scan for Access Points and wait for your home Wi-Fi network to appear in the list.Select your home network and select the WPA option.
3. Click Attack and enter the path into the wordlist containing a list of possible passwords.
4. Fern WiFi Cracker will start trying password combinations from the wordlist.
5. If the password is found, Fern WiFi Cracker will display it on the screen. You can use these passwords to better secure your network, for example by replacing them with stronger passwords.
