What could happen if you use public Wi-Fi without precautions?

Using public Wi-Fi can expose users to various risks if proper precautions are not taken. Each of the potential risks outlined in the answer choice encompasses a different aspect of these dangers.

When using public Wi-Fi, network administrators or anyone with access to the network can monitor the traffic that flows through it. This means they could track browsing activities, capturing the sites you visit and potentially any data you transmit over the connection. This scenario highlights the lack of privacy typical in unsecured public networks.

Additionally, public Wi-Fi networks are often less secure than private ones, making it easier for malicious software (malware) to be introduced to your device. An attacker could design a malicious hotspot that appears legitimate, luring users into connecting and then deploying malware that compromises devices.

Moreover, unauthorized users can exploit the vulnerabilities of public Wi-Fi to intercept data, allowing them to gain access to sensitive personal information, such as login credentials, financial details, and other private data. This theft of information can happen through various methods, like man-in-the-middle attacks.

Therefore, the correct answer reflects that all of these significant risks are associated with using public Wi-Fi without appropriate precautions, emphasizing the importance of ensuring your connection security before accessing public networks.
