Most Wi-Fi equipment manufacturers deliver routers that are configured for simple and rapid installation. This often means that all the security options are deactivated.
There are two problems with this:
- A hacker could spy on your internet connection and obtain, for example, your email password. On the other hand, the hacker won’t be able to read your personal passwords for your online accounts (you can easily check that you are on a secure site by looking for “https” (and not “http”) in your browser’s address bar).
- You are responsible for the use that is made of your internet connection. Unwanted visitors may go to disreputable websites or use your connection in an abusive way. When this happens, the intrusion does not leave any trace, and it will therefore be up to you to show that you did not know anything about it.
Good habits for limiting the risk of fraud:
Ensure that the connection to your Wi-Fi network is encrypted (e.g. using a personal and complex WPA2 key) and also, make sure to change the Wi-Fi router's admin console default password.
