Fern Wi-Fi Cracker is a Wireless security auditing tool written using the Python Programming Language. This program is able to crack and recover WEP/WPA/WPS keys and run other network-based attacks on wireless or ethernet-based networks. This is one of the best GUI-based Wi-Fi crackers for Linux available in the market today. So by popular demand, we are going to see how to hack Wi-Fi using FERN Wi-Fi cracker on Kali Linux.
Fern comes preinstalled in Kali Linux. It is also automatically updated when kali is updated.

Fern Wi-Fi cracker will automatically begin the best attacks on the network. When it captures a handshake file, and it will begin performing a brute force attack on the handshake file.
Step 8. If you have read my previous articles on Bruteforce, you know that it is a process of trial and error. Depending on the security and complexity of the password, the time taken to crack the password will vary. It will also vary depending on the hardware used.
Step 9. Once the attack succeeds, you can see the passwords in “Key Database.”
Step 10. Once the hack is successful, you can view the password in the key database whenever you want. As shown in the image below:
Congratulations you have learned how to hack any WiFi with a fern Wifi cracker with these easy steps. With the help of this tool, you can probably hack most Wifi networks used today.

Commonly asked questions about hacking Wi-Fi with fern Wifi cracker:
While hacking and pentesting Wifi networks, the following questions might come into your mind:
Q1. It is not working on my pc. What do I do?
Make sure you have an internal wifi card. Desktops do not always have them, so this hack is good for laptops and portable devices. So that is what I will recommend. This only works on the Linux distro. Kali Linux is recommended
Q2. Does the hacking world provide customer support for this software?
No, we do not provide any support for this software. This is an open-source tool we reviewed.
Q3. Can I hack Wi-Fi without WPS?
Yes, you can with other attacks. WPS is the best and fastest method. However, that is not the only method so you can always try phishing and other attacks.
Q.4 Can I use an external USB adapter for this hack?
Of course, you can. You can use both external and internal wireless adapters for hacking Wi-Fi with a fern wifi cracker.
