What is the risk associated with using public Wi-Fi?

Using public Wi-Fi poses a significant risk because data transmitted over these networks can be intercepted by malicious actors. Public Wi-Fi networks, such as those found in coffee shops, airports, or libraries, often lack robust security measures. This vulnerability allows cybercriminals to engage in activities such as packet sniffing, where they can capture and analyze the data packets being sent and received by users. Sensitive information such as login credentials, credit card details, and personal messages can be easily accessed if the data is not encrypted.

In contrast to this major risk, aspects like internet connectivity speed, the fact that public Wi-Fi is typically free, or the need for additional software installation, while they might be considerations for users, do not encapsulate the primary cybersecurity threat involved with these networks. Prioritizing data security over convenience is essential when connecting to public Wi-Fi.
