Public Wi-Fi security risks and prevention measures

Public Wi-Fi networks in regions such as Gipuzkoa, Spain, and Maipú, Chile, present significant cybersecurity risks due to their lack of encryption and unknown administration. Using open networks in cafes, hotels, or shopping centers can expose users to man-in-the-middle attacks, where attackers intercept sensitive traffic including passwords, private messages, and banking details.

To mitigate these risks, experts suggest several security habits. Users are advised to verify the exact name of a network with staff to avoid fraudulent networks with similar names, avoid conducting financial transactions or accessing home banking while connected to shared networks, and ensure all mobile applications are updated to patch known vulnerabilities. Additionally, using a Virtual Private Network (VPN) can provide necessary encryption to protect data in transit.
