Wireshark Basics // How to Find Passwords in Network Traffic

so for today's video, I'm gonna be giving you guys a quick overview of Wireshark some of the things that you can do to monitor your at-home network, and a quick demo to show you how you can find passwords in HTTP traffic.

so for those of you that don't know Wireshark is a free open source software that you can use to analyze packets, there is both a Mac and a Windows version that you can download it's a super simple process basically what you do is you download the image file from the website you're a few clicks away and then it is right there in your applications.

What is Wireshark?

A Wireshark is a very handy tool it is very useful when it comes to networking it helps researchers to do some data analysis when it comes to the networking traffic or it can also be used by hackers for security purposes.

Now whenever we have this data that belongs to different layers they have a name can be a message it can be just anything, for example, we have segments we have different names that belong to different layers than we have datagrams we have packets we have frames and we have bits so as I said initially each and everything is in what we can see and what is readable what is discernible but as they move downwards the data how bit how the data travels when it moves from one computer to another this is this logical model and the data flows downwards

How to Install Wireshark 

In this video, I'm going to show you how you can download and install why shark on your operating system Wireshark.ORG is a free and open-source packet analyzer used for network troubleshooting analysis software and communication protocol development, and also education so let's see how we can install why sharks 

so first of all open your favorite browser and search for Wireshark and most probably the first link which will appear here will be from just click the first link which is for the Wireshark dot orgy and once you are inside the Y Shack dot o-r-g website you just need to search for the Downloads button which is here in this case so I'm going to just click on the Downloads.

Wireshark Tutorial for Beginners

A Wireshark tutorial for beginners that shows users how to track network activity, view specific frame, TCP, IP, and HTTP information, view specific packets being sent and received on the network, view information within those packets, and spot malicious or suspicious network behavior.

How to: Use Wireshark

The very important and very useful tool is called Wireshark. now if you don't know about Wireshark a packet capturing tool that you can use to package packager capture incoming packets that your network interface or wi-fi card or Bluetooth card can see over the air over the ethernet wires or um you can also analyze packets.

so we're going to be doing a little bit of both today Wireshark does have some sample packets that you can analyze look at test your skills to see some stuff and then also just to see what this packet captures should look like for different internet protocols and stuff like that.

Top 10 Wireshark Filters // Filtering with Wireshark

In this video, we're gonna take a look at the top 10 Wireshark filters that I like to use for setting display filters. So probably the reason you're here is that from time to time we might need to set a filter and we don't quite know what the syntax is for it.

So here are some common ones that I like to use and no doubt they will be of use to you as well.

Filtering with Wireshark is here:

  • A station filter or an IP filter [ IP.addr == ].
  • Set a filter for a protocol [ TCP or DNS ].
  • A TCP or a UDP port number [ TCP.port == 443 ].
  • Packet loss or retransmissions on the network [ TCP.analysis.flags ].
  • how we can remove some of the noise and when we're looking in a trace file[ !(arp or ICMP or DNS) ].
  • Follow tcp stream 
  • Tcp contains facebook 
  • HTTP dot response [ http.response.code == 200 ].
  • HTTP dot request [ http.request ].
  • how many syn connections are coming in to a  system where they're coming from and what those ports look like [ tcp.flags.syn == 1 ].
