Network Packet Analyzer (Wireshark)

The application analyzes exported Wireshark packets in JSON format. see here Currently, it displays the following:

1. IP location details (city, state, country, etc...)
2. List of unique IP addresses
3. List of unique MAC addresses
4. List of unique TCP & UDP port numbers
5. DNS queries / answers
6. HTTP request methods, user agent, etc..

There is an HTML front-end for the app at the root endpoint /. This allows you upload your exported json file for parsing. The server code extracts the data and responds back to the client with JSON. I created an endpoint located at /api/packet/data that displays the results in HTML/EJS table format, http://127.0.0.1/api/packet/data. If you need customized output all you have to do is edit the functions inside packetAnalyzer.js file.

I included MongoDB Atlas into the full-stack app. It reads from the last packet in the collection and Express renders it to the /api/packet/data endpoint. See examples of it at the bottom of the README.md

Getting Started

Ideally, it should be as easy as issuing npm install, filling in your .env file and nodemon index.js It's been tested on Linux (Debian based) and Windows 10.

• To get the IP address location details I used the ip2location.io API.
• For MongoDB Atlas, Place your connection string info inside the .env file. There is an env.example.

Installation

Clone the repo

git clone https://github.com/jim3/Network-Packet-Analyzer.git

Install dependencies

npm install

Usage

Capture some Wireshark packets, use a capture filter for better results:

• Wireshark host <YourIP> and not broadcast and not multicast and ip then File > Export Packet Dissections > As JSON

• TShark: ./tshark -i <interface> -T json -c 100 > <path to json file>

Run the script

nodemon index.js

Open your browser and go to:

1. http://localhost:3000/ and upload your exported wireshark file, the server will respond with the details in JSON.

Vist http://localhost:3000/api/packet/data to view the results of the last file written to your MongoDB Atlas database/collection.
