When connecting to a Wi-Fi network we can have security problems. It is possible that it is a scam and has the sole purpose of stealing our personal data. What can we do to prevent it? In this article we are going to talk about 3 things you should look at when you are going to connect to a public network. The objective is to prevent any malware from sneaking in or having any security problem.
What to look for before using public Wi-Fi
An attacker could create a fake Wi-Fi network in places like shopping malls, airports, or libraries. They are spaces where many users can connect and that will mean that they have a greater probability of success. You will be able to avoid this problem if you take into account some factors.
Network name
If, for example, you are going to connect to a network in a cafeteria, take a good look at the name. You can see that it is really the one in that place and compare it with the poster where you can see the access code. An attacker can create a wireless network with a similar name and the same password, with the aim of scamming the victim into thinking they are on the legitimate network.
Therefore, the first tip is as simple as looking at the name of that network. Take note that it does not have any letter or digit that is different and could lead to the entry of attackers. Look at any details that might be different than they should be.
Encryption type
It is also important to connect to networks that have a password, as this will help prevent anyone from gaining access with malicious intent. But regardless of whether or not you have a password to access it, it is a good idea to look at what type of encryption it has. They are not all the same and not all are going to really protect that network from potential intruders.
For example, ciphers like WPA or WEP are old and obsolete. There are programs that can break a weak key that uses this encryption. A cybercriminal could break into a network in this way. Ideally, it should have at least WPA-2 encryption , although the most current today is WPA-3 . Of course, there are not yet many devices compatible with this latest version, so it is normal that you find mostly WPA-2 encryption.
Data request
Also, a third point to keep in mind is that they may ask for data to enter that Wi-Fi network. This is common in places like a shopping mall. Sometimes this is harmless and nothing should happen, but on other occasions it can be the way they use to steal personal data and put it up for sale on the Internet.
Our advice is that you observe this very well when connecting to a Wi-Fi network. Whenever you can, avoid networks where they will ask you for personal information such as your e-mail or phone number. If you need to connect, you can choose not to enter your real data and use an alternative email to receive the code and enter, without having to compromise your privacy.
In short, as you can see, it is important to take into account some things to connect to a public Wi-Fi network safely. Avoid risks that may affect your security and privacy. You will find options to connect to Wi-Fi away from home, but not all of them will be reliable.
