I am using Kali Linux because of its simplicity and powerful tools installed.Wifite is a Linux platform tool (available on Kali, Backtrack 5, BlackBuntu, BackBox and Pentoo Operating Systems) which is used to attack multiple encrypted networks (WEP, WPA/2 and WPS) in a row.
Here are some types of WIFI that you should know about:
1.WEP stands for Wired Equivalent Privacy Usually less than 10 Minutes (2 min. in our case) – 99.9% Chances.
2.WPA or WPA2 stands for Wi-Fi Protected Access & Usually few seconds to Never – 20% Chances.
3.WPS or WPS Enabled WPA/2 stands for Wi-Fi Protected Setup Usually few hours (2 to 12 hours) – 50% Chances..
[Important]Step Before Hacking wifi:
In Terminal , type airmon-ng start wlan0 and kill the shown processes by typing kill PIDnumber.
