When we login using username and password the the there are two ways the data can be sent. One is GET and another is POST. GET can't be used in case of sending sensitive data as it concats data to URL which makes data visible. So in our case data is sent via POST.
To filter all traffic for POST data type in following command in filter section
http.request.method == “POST”
Step 3: Filter POST data for Username and Password
Right click on the filtered POST data and select Follow TCP Stream

Hashcat –m -0 –a 0 /root/wireshark-hash.lf /root/rockyou.txt
And here you get your real password. We hope you use this tutorial for only testing purpose and wont harm anyone.
