Network Packet Sniffer

This is a simple network packet sniffer application built with Flask and Scapy to capture, analyze, and display network packets in real-time. It also includes features to detect suspicious activities like ARP Spoofing and unusual port usage. The application provides a web interface where users can:

• View packet statistics (total, ARP, TCP, UDP packets).
• Apply filters to capture packets by IP address and protocol (ARP, TCP, UDP).
• Detect suspicious network activities (e.g., ARP spoofing).
• View suspicious activity logs in real-time.

Features

• Real-Time Packet Capture: Sniff packets from the network in real time.
• Packet Filtering: Filter captured packets by IP address and protocol (ARP, TCP, UDP).
• Suspicious Activity Detection:
  • ARP Spoofing Detection: Detect and log ARP spoofing attempts.
  • Unusual Port Usage Detection: Detect unusual port usage outside the range of normal ports (1-1024).
• Traffic Statistics: Display statistics for total packets, ARP, TCP, and UDP packets.
• Suspicious Activity Logs: Display logs of suspicious activities like ARP spoofing and unusual port usage.

Requirements

• Python 3.x
• Flask
• Scapy
• Threading

To install the necessary Python dependencies, use the following command:

pip install flask scapy
