ESP32 WiFi Security Audit Demo

What is your project about?

The ESP32 WiFi Security Audit Demo is an educational platform that demonstrates wireless network security concepts using affordable hardware. It combines a network scanner, vulnerability analyzer, and captive portal simulator in one compact device, designed to help users understand both the offensive and defensive aspects of WiFi security.

The system operates through three primary modules working together:

• WiFi Scanner: The ESP32 continuously scans the environment for wireless networks, collecting details like SSID, signal strength, encryption type, and channel information.

📷 The system displays all detected networks in the environment

📷 Networks are stored in memory for analysis

• Security Analysis Module: The collected network data is analyzed to identify potential vulnerabilities such as open networks, weak encryption protocols, or suspicious patterns.

• 📷 Detailed security analysis highlights potential vulnerabilities

• Educational Captive Portal: A simulated access point demonstrates how rogue networks can capture credentials through phishing techniques.

All data collected can be stored locally and optionally synchronized to Google Sheets for further analysis and educational purposes.

The system provides a comprehensive command interface through the serial monitor, making it easy to control and demonstrate different security concepts.
