This is a detailed article on how to capture WPA/WPA2 Wi-Fi handshakes and crack the hash to retrieve a networks password. The article is purely written for the education value of showing you how easy it is to break into your own home Wi-Fi network if you use a weak password.
Alternatively, if you are an aspiring Pentester or RedTeam enthusiast you can use this article as a guide on your own networking equipment to learn how to test the security of any Wi-Fi network. I do not condone using this guide on unsuspecting individuals without their explicit consent.
