PacketDuck is a modern, client-side Network Packet Analyzer and Threat Intelligence Dashboard. It parses PCAP files directly in the browser and leverages Google Gemini AI to provide forensic insights, risk scoring, and threat detection.

• Client-Side Processing: Parses .pcap files entirely in the browser. Your raw packet data stays on your machine until you explicitly choose to analyze threats.
• AI-Powered Threat Intel: Uses Google's Gemini model to analyze traffic patterns, payload anomalies, and generate an executive security assessment. ![]
• Interactive Timeline:
  • Attack Detection: Heuristics for SQL Injection, XSS, RCE, and Shellcode.
  • Behavioral Analysis: Detects Traffic Bursts, Port Scans, and Lateral Movement (Pivoting).
  • Context Linking: Visually links related events (e.g., a burst followed by a new connection).
• Visualizations:
  • Protocol Distribution Charts.
  • Active Conversations Table.
  • Geo-IP Mapping for external hosts.
• Forensic Tools:
  • Payload inspection with ASCII preview.
  • VirusTotal integration for IP reputation checks.
  • PDF Report Generation.

• Frontend: React 19, TypeScript, Vite
• Styling: Tailwind CSS
• AI: Google GenAI SDK (Gemini 1.5 Flash)
• Visualization: Recharts, Lucide React
• Utilities: jsPDF, html2canvas

1. Clone the repository

   git clone https://github.com/yourusername/packetduck.git
   cd packetduck

2. Install dependencies

   npm install

3. Configure Environment Variables Create a .env file in the root directory:

   # Required for AI Analysis
   GEMINI_API_KEY=your_google_gemini_api_key
   
   # Optional: For IP Reputation checks (Free tier works)
   VT_API_KEY=your_virustotal_api_key

4. Run the development server

   npm run dev

1. Google Gemini API: Get your key from Google AI Studio.
2. VirusTotal API: Sign up at VirusTotal to get a free public API key.

PacketDuck performs the heavy lifting (PCAP parsing) locally.

• Local Parsing: The raw binary parsing happens in your browser's memory.
• AI Analysis: When you trigger the AI analysis, a subset of metadata (summarized logs, top protocols, and specific payload snippets) is sent to the Google Gemini API for processing.
