An Experimental Analysis for Public Wi-Fi Attacks

The research delves into the vulnerabilities prevalent in public Wi-Fi networks, specifically focusing on ARP spoofing, DNS spoofing, and 4-way handshake attacks. ARP spoofing entails the deceptive manipulation of address resolution, while DNS spoofing capitalizes on weaknesses in the Domain Name System to redirect users to malicious websites. Meanwhile, the 4-way handshake attacks aim at the security mechanisms of Wi-Fi networks. The main objectives are to comprehensively evaluate the effectiveness of these attacks, identify potential threats to user data, and propose mitigation techniques to enhance the security posture of public Wi-Fi setups. Four testbed experiments have been set up and the results have been further analyzed. The findings of this research are instrumental in advancing our understanding of the risks associated with public Wi-Fi networks and in facilitating the development of robust defense systems against unauthorized access and potential data breaches. Finally, the in-depth analysis of ARP spoofing, DNS spoofing, and 4-way handshake attacks in public Wi-Fi networks, along with the proposed mitigation techniques, constitutes a valuable contribution to the ongoing efforts to fortify the security posture of these widely utilized networks.
