Multi-Protocol Communication and Security System Using ESP8266/32

In the rapidly evolving landscape of cybersecurity threats, multi-protocol communication devices play a crucial role in penetration testing and security research. This paper presents a Multi-Protocol Communication and Security System using ESP8266/32, designed to explore cybersecurity vulnerabilities across different communication protocols, including WiFi, RF, and RFID. The project encompasses four distinct tools: Cyberduck (WiFi Rubber Ducky), Signal Spy (RF Signal Scanning and Replay), ZapTag (RFID Reading, Writing, and Cloning), and ARP Spoofer (Network Scanning and ARP Spoofing). Each tool is developed for ethical hacking, security testing, and research purposes. This paper discusses the hardware and software implementation, security implications, and future improvements.
