AI PCAP Analyzer

AI PCAP Analyzer is a next-generation network analysis tool that combines the power of Wireshark with a local Large Language Model (LLM) to act as your intelligent security analyst.

Note

The application is under development. I welcome suggestions on how to improve it or any bugs you encounter.

🚀 Features

• Local AI Analyst: Powered by Ollama (recommended model: gemma3:12b).
• Conversation Memory: The AI remembers your context and files.
• Smart Visuals: Instant red/orange highlighting for network anomalies (Retransmissions, RSTs).
• Multi-language Support: 🇮🇹 🇺🇸 🇨🇳 🇷🇺 (Italian, English, Chinese, Russian).
• Contextual Understanding: Rename captures (e.g., "Firewall Logs") to give the AI better context.
• Privacy First: All analysis happens locally. No data leaves your machine.

🛠️ Prerequisites

1. Python 3.10+
2. Node.js 18+
3. Wireshark/Tshark installed (sudo apt install tshark).
4. Ollama installed and running.

AI Setup

This project requires a running Ollama instance.

1. Install Ollama from ollama.com.
2. Pull the recommended model:

   ollama pull gemma3:12b

3. Make sure Ollama is accessible. By default, the app expects it at http://127.0.0.1:11434 (update backend/chat.py if different).

📦 Installation

⚡ Quick Start (Recommended)

You can use the automated installer to set up both backend and frontend:

chmod +x install.sh
./install.sh

Then start the application:

./run.sh

Manual Setup

Backend

cd backend
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
./run.sh  # Starts backend on http://localhost:8000

Frontend

cd frontend
npm install
npm run dev # Starts frontend on http://localhost:5173

🖥️ Usage

1. Open http://localhost:5173.
2. Drag & drop a .pcap file.
3. Click the Robot Icon (🤖) to open the AI Analyst.
4. Ask questions like:
   • "Why is the connection resetting?"
   • "Show me all DNS traffic from 192.168.1.5"
5. Use the Language Switcher in the top right to change the interface language.
