Relying on public Wi-Fi for sensitive transactions poses significant risks, including exposure to data breaches and cyberattacks. Public networks often lack proper security measures, making it easier for hackers to intercept communication or access personal information. Without encryption, data transmitted over public Wi-Fi can be vulnerable to unauthorized access, leading to identity theft or financial loss. To mitigate these risks, users should avoid conducting sensitive transactions on public Wi-Fi or employ VPNs to secure their connections. Awareness of these vulnerabilities is essential for maintaining online security in shared networks.
