| Wi-Fi Network |
The fact that we are connected to an unsecured WiFi network could mean that we are being spied on. For example, they can intercept the messages we send if they are not encrypted, find out what websites we visit, etc. They can even redirect us to malicious pages, created solely for the purpose of spying on malware and stealing information.
1. Look at the type of encryption:
The first thing to look at is whether or not the Wi-Fi is protected. Do you have a password? If you do not have it, it means that the network is open for anyone to enter. It may have been created for fraud, but it could also be that an income was entered with malicious intent taking advantage of the fact that it is open.
But regardless of whether it contains a key or not, you must also consider the type of encryption. The two most reliable today are WPA-3 and WPA-2. In these cases, the network will be protected. If you have outdated WPA or WEP encryption, it may be exploited by the software.
2. Note the name WI-FI:
The name of a WiFi network can also give us clues about whether it is reliable or not. It is true that an attacker can create any network with any name and even impersonate a secure Wi-Fi network, but it is still worth taking a closer look at the name it bears. 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 simply want the victim to enter, click on that network, and connect so they can steal data or infect the device.
3. The network asks for a lot of information:
When connected to a Wi-Fi network, they may sometimes ask us for certain data. For example, a form where we have to fill in things like name, email address, or phone number. Without it we would not be able to connect to the network, because they limit it to users who provide their data only.
This does not mean that it is a dangerous network, but it does mean that they are asking for a lot of information. It could be a scam, a way to cheat, to steal information. Avoid networks that may require a lot of data.
4. If it is running suspiciously slow:
In this case, you will have to connect to be able to use this trick to detect a dangerous Wi-Fi network. Of course, you should keep in mind that the fact that the network is slow does not mean that it is unsafe, far from it, but sometimes it is. For example, if you are in a public place where there is a network to supply 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 has created a parallel network, pretending to be the real network, through your mobile connection. This is why it will go slower than usual and can give us clues that something is wrong.
5. The pages open strangely:
Another trick is if you notice that the pages open strangely. This could happen because an intruder was able to modify the router's DNS and it leads us to a completely different page than the one we're trying to do. This way it can steal passwords or data or sneak some kind of malware into the system.
If you see that you are trying to access a website and another site already appears, with a different range, suspect Wi-Fi. It is probably not secure and it is best to disconnect as soon as possible to avoid problems of any kind.
