Emulate TLS Fingerprinting On Network Namespaces Using Ja3/Ja3s & Mercury

Run Locally

Clone the project

Go to the project directory

  cd my-project

Install dependencies

  sudo apt install iperf3
  sudo apt install openssl -y
  sudo apt install ja3
  sudo apt install wireshark

First Go into sudo mode

  sudo su

Run script to make the network

  ./name_s.sh

Screenshots

Running the Project

open two terminal

In First Terminal go in Red bash

  ip netns exec red bash

In Second Terminal go in Blue bash

  ip netns exec blue bash

Open wireshark in Red (client) choose ethred interface start capturing packet

  wireshark 

Make Blue as Server using iperf at port 443

  iperf3 -s -p 443

In Red connect to Blue (server)

  openssl s_client -connect 10.0.2.2:443

wireshark file save in .pcap file format

so in this you will get client hello msg which will helpful for calculating tls fingerprint

using ja3 we can calculate fingerprint

  ja3.py filename.sh
