You often enjoy checking your social media accounts while drinking a cappuccino at the local coffee shop.


1::There might be extra hidden charges that I am not aware of.
2::Other people connected to the open network can see what you are doing.
3::Personal data can be stolen from my communications on the open Wi-Fi.

This is an incorrect answer, unfortunately. There are several risks associated with using open Wi-Fi, due to the fact that the absence of a passphrase results to visibility of your network traffic by everyone in range. Hence, people can see – with appropriate tools - what web pages you’re visiting, as well as what you’re typing into unencrypted web forms (that is in web sites starting with http instead of https). Therefore, personal data can be stolen. A further risk is that if infected computers are connected to this kind of network, they may attempt to infect your device as well; such an infection may have several adverse effects, such as deletion or steal of your personal data, as well as monitoring your activities.

The shop has free open Wi-Fi and you can connect to it with your tablet without using any passphrase. However, one of your friends told you that there might be dangers with such open networks.

What could these dangers be?
