What risk is associated with using public Wi-Fi?

Using public Wi-Fi presents the substantial risk of exposure to data theft. When individuals connect to unsecured public networks, such as those commonly found in cafes, airports, or libraries, their sensitive information becomes more vulnerable to interception by malicious actors. This is primarily because these networks often lack robust security measures, making it easier for hackers to access unencrypted data transmitted over the network.

In such environments, attackers can deploy various techniques to eavesdrop on internet traffic, potentially capturing personal information, login credentials, or financial data. Therefore, users should exercise caution when using public Wi-Fi by avoiding high-stakes activities like online banking or shopping and considering the use of virtual private networks (VPNs) for added security. This highlights the importance of being aware of the risks and taking preventive measures to protect personal information in public settings.
