What, How to, and Why?: Wireshark

What, How to, and Why?: Wireshark

Now if you have never heard of Wireshark before, I am going to question how you got here, but I will teach you what Wireshark is, how to use it and why you should use it.

Now I’ll assume that you don’t have it installed yet, (if you already do you can skip ahead) install Wireshark here: https://www.wireshark.org/#download. You will have a Windows 64 and 32 bit and a Mac OS installer each with it’s own link, choose respectively and follow the prompts. Once you have it downloaded you should have a shortcut on your desktop and now we can begin.

Now that you have this on your computer you must be wondering what it is, and this will take a little while to fully understand. On the website it has it spelled out for what it is “ It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions.” Simply you get to see what people are doing on your network and other networks that you go to. For example you could simply go to Starbucks and using this tool on your phone, know what everyone is doing on their devises on the Starbucks WiFi.

Now this is where you get to learn what to do with it, one simple thing you can do is to see images and videos that are downloaded on the network. This is quite easy, and very scary once you realize how to do it. Once you have wireshark open start a recording, wait a few minutes and go browse on google for a few minutes, download a few images and visit a few websites. Now once you have done that go to file and Export Objects → HTTP…

Now you have a new window open this will show you all of the downloads to see one all you have to do is right click it, download it to your desk top and you will see the image on right there. These few steps is all it takes to see all that is happening on someones WiFi.

Now, you might be wondering why you would want to do this and it’s quite simple, security. Now you know how to see what others can see on your network and that is just one step in the hike to get all the information that you need to keep your information safe.
