Intercepting Data Sent be Our Computer

Many a times we need to sniff  data that is sent and received from our computer or we arent aware that what kind of information a software is sending to server
So in this blog post i will explain and teach you how to intercept data on desktop or a laptop device



Requirements
1. A desktop Pc With Windows Installed
2. Smartsniff from Nirsoft (download Link Here)

And Some 10-15 Minutes Understanding Procedure


So Lets Start Downloading Smatsniff
So Which One Is to Be Downloaded
There Are 3 Variants Available

I prefer One with uninstall support so that when I'm done with it I can easily unistall it

So after downloading it
install the same

Installation is quite simple
Just Click Next
Next
Install


Depending On Version and Dependencies it would ask for pcap drivers
if it prompts do download it


Now How to use it

The Main Screen When On First startup Looks Like This

Click On Green Play Button
You might get "Capture Options" dialog that looks something like this

Now I Have Selected Raw Sockets and in that there are many connections that could be sniffed/Intercepted

So Choose A Proper Network
once done click okay

You Are Ready To Go


How to use it

Once you have setup now you would be able to see packets of data in main window some what like this

now all data that is sent and received is view able in this window

Mostly when Softwares interact with servers they go through port 80 so you can now select port 80 and can view data sent and received

A Note: As websites using HTTPS , Data is encrypted those data packets cannot be view here

Although this can help you to debug you applications or can even help you to bust a malacious app that may be sending any of your personal data

you may also come to know what data is being actually sent to different websites
