How to see if a Wi-Fi is reliable
Connecting to an unsecured network can mean that we are being spied on. For example, they could intercept the messages we send if they are not encrypted, see which sites we visit, etc. They might even redirect us to malicious pages, created only for the purpose of malware strain and steal information.
View Encryption Type
The first thing you should check is if this The Wi-Fi network is protected or not. Do you have a password? If you don’t have one, it means the network is open to everyone. It may have been created to scam, but it could also be that an intruder entered with malicious intent taking advantage of the fact that it is open.
But beyond whether it has a key or not, you also need to look at the type of encryption. Today, the most reliable are WPA-3 and WPA-2. In these cases, the network will be protected. In case you have WPA or WEP encryption, which are outdated, they could be exploited through software.
observe the name
The Wi-Fi network name it can also give us clues as to whether it is reliable or not. It is true that an attacker can create any network with any name and even impersonate secure Wi-Fi, but it is still worth taking a good look at its name. The goal is to avoid connecting to a network that could become a problem.
For example, names like “Free Internet”, “Free Wi-Fi” and the like can be used as bait. They may just want the victim to come in, click on that network, and connect so they can steal data or infect the device.
The network requires a lot of information
When connecting to a Wi-Fi network, they can sometimes ask us for certain information. For example, a form where we must fill in elements such as our name, our e-mail address or our telephone number. Without it, we could not connect to the network, because they limit it only to users who give their data.
That doesn’t mean it’s a dangerous network, but it does mean that they ask for too much information. It could really be a scam, a way to cheat, to steal information. Avoid networks that may require a lot of data.
It turns strangely slowly
In this case you will have to connect to be able to use this trick to detect dangerous Wi-Fi. Of course, you should keep in mind that just because the network is slow doesn’t mean it’s insecure, far from it, but sometimes it does. An example is if you are in a public place where there is a network to provide many users, that place is empty but you still see that the network is slow and you have maximum coverage.
This can happen because a hacker might have created a parallel network, which simulates to be the real one, thanks to the connection of your mobile phone. This is why it will go slower than normal and could give us clues that something is wrong.
Pages open strangely
Another tip is if you notice pages opening strangely. This can happen because an intruder may have modify the DNS from the router and it takes us to a totally different page than the one we’re trying. This way, it could steal passwords, data or introduce some kind of malware into the system.
If you see that you are trying to access a website and another one actually appears, with a different domain, suspect the Wi-Fi. It may not be secure and it is best to disconnect the as soon as possible to avoid any problems.
In short, as you can see, you can detect if a wireless network is dangerous. The objective is to ensure that the connection is secure, that our personal information is not compromised and that we can navigate correctly. Checking the security of your router, to avoid intruders, is also a good idea.
