What is Fern WiFi Cracker and how does it work?
Fern WiFi Cracker is a GUI-based WiFi password cracking tool that comes pre-installed with Kali Linux. It is designed to crack WEP, WPA, and WPA2 passwords using various methods such as dictionary attacks, brute force attacks, and WPS attacks. Fern WiFi Cracker works by capturing the WiFi network’s handshake packets and then using the captured packets to crack the password.
Fern WiFi Cracker uses a combination of techniques to crack WiFi passwords, including dictionary attacks, which involve trying a list of common passwords, and brute force attacks, which involve trying all possible combinations of characters. It also supports WPS attacks, which exploit a vulnerability in the WPS protocol to crack the password. Fern WiFi Cracker is a powerful tool that can be used to test the security of WiFi networks.
What are the system requirements for running Fern WiFi Cracker?
To run Fern WiFi Cracker, you need to have Kali Linux installed on your system. Kali Linux is a Linux-based operating system that is specifically designed for penetration testing and digital forensics. You also need to have a compatible wireless network adapter that supports packet injection and monitor mode. Some wireless network adapters may not work with Fern WiFi Cracker, so it’s essential to check the compatibility before running the tool.
In addition to the system requirements, you also need to have a good understanding of Linux and WiFi networking concepts to use Fern WiFi Cracker effectively. You should also have a list of dictionaries or wordlists that you can use to crack the WiFi password. Fern WiFi Cracker is a powerful tool, but it requires some technical expertise to use it effectively.
How do I install Fern WiFi Cracker on Kali Linux?
