Interesting question. Normally I would use Kali Linux for this task. Kali has built in tools that make WiFi cracking easier. But if you are forced to use a Windows OS for this task, I would use the application Wireshark. Wireshark is built for network reconnaissance. But, that is not what the question wanted. You want to know how to hack Wifi using cmd.exe
First of all, cmd is a little outdated. For this task, I would use Powershell. If you are working on Windows 7 or later OS, you should have Powershell pre-installed. While there are some wifi network using cmd. You my find using cmd is cumbersome.
Secondly, Microsoft has already written a document describing what you want to do. Read ‘Get Wireless Network SSID and Password with PowerShell’. This document should point you in the right direction.
Finally, know that what you are attempting to you is most likely illegal in your area. You want to be well versed in your country’s laws. In my area, passively monitoring a wifi network is usually legal, attempting to access that network is illegal. Do not send deauth attacks. Do not attempt to log onto a network that you do not have formal access to. Seriously, do not do it.
Have fun and be safe!
