Public Wi-Fi networks, often found in public spaces like cafes and airports, provide convenient internet access but come with significant security risks. Cybercriminals can exploit these connections to intercept sensitive information, making it essential for users to understand the associated dangers. To enhance security, the best practice is to avoid public Wi-Fi when possible; if necessary, users should confirm the legitimacy of the network, avoid sensitive transactions, update their software regularly, disable file sharing, and ensure they are using HTTPS websites. Lastly, forgetting the network after use can further safeguard against unauthorized access.
