Step-by-step demonstration of how easily a misconfigured Wi-Fi network is compromised and what information it leaks.
The ease of hacking WPA2-protected Wi-Fi networks using Fern Wifi Cracker on Linux, a USB network adapter in monitor mode and the RockYou brute-force password dictionary.
In the digital age we live in, the security of our Wi-Fi networks is of utmost importance. However, it is astonishing how easy it can be to hack into a Wi-Fi network protected with the WPA2 security standard. In this article we explore the process of hacking such networks using tools like Fern Wifi Cracker, a USB network adapter in monitor mode, and the famous RockYou brute-force password book.
Fern Wifi Cracker is a powerful wireless network auditing and security tool that runs on Linux. With this tool we can perform brute-force attacks and retrieve WEP/WPA/WPS keys. Its user-friendly graphical interface makes it easy to use, even for those who are not hacking experts.
To carry out a successful attack, we need a USB network adapter that supports monitor mode, which allows us to capture Wi-Fi traffic in our area. Make sure your adapter is compatible before getting started.
Lastly, we need the RockYou brute-force password book. It contains an extensive list of commonly used passwords, frequently used for Wi-Fi networks. Combining that list with the hashing process used in WPA2 authentication allows us to guess the correct password and gain access to the protected Wi-Fi network.
Once on your home network, an attacker can see all devices: Alexa, Chromecast, TVs, smart-home gear, and take control without problems.
