Neighbor connection

Hello,

I'm afraid hiding the SSID doesn't change anything in terms of security ;(

And MAC blocking is also ineffective if the WPA2 password is compromised, as the hacker who has captured the exchange of keys (and can read them by knowing the password) can communicate directly with the victim's computer, without going through the WiFi point.

If the password is not compromised, then there's no connection to the WiFi point and MAC blocking is not useful.

But I think that in the scenario presented here, either the WiFi is open, or the password is compromised, otherwise I don't understand how communication via WiFi between the smartphone and the computer would be possible, since the computer is supposed to accept only frames encrypted with the keys exchanged with the WiFi point.

I wonder which tool displays this notification; it seems, a priori, that it is not the Windows network, and we should check if your box has seen this connection from the neighbor's mobile.
In any case, hiding your SSID does not prevent you from connecting as long as it does not change, but even if you do change it, it is enough to enter it manually by choosing to connect to an unknown network.

Good evening to you!

So, not only do I have to change my password, but on top of that, you're also going to tell me to change it regularly???

Thank you.

The fact that a smartphone was able to request access to your computer via the network means that this smartphone was indeed connected to the same network as your computer.

So it seems that the neighbor has connected to your network despite the password protection, and even if this does not hinder the proper functioning of your computer, and although it does not directly pose a risk to your data, you are particularly responsible for what this person does on the Internet using your connection.

“What else is there to do or know?”

I highly recommend that you change your WiFi password if you haven't already done so! :)

“Moreover, I do not understand the words 'open wifi'. On my livebox, I have disabled the orange hotspot.”

An open WiFi is a WiFi without a password, accessible to everyone. The connection to the network is not encrypted. The lack of this encryption at the network level does not, of course, prevent the use of encryption at the application level (such as HTTPS) for secure browsing.

And he displays freely, in the waiting room, the password for his own wifi.... He is the only one doing this, unlike other retailers located in the same shopping center.

I connect to his wifi to use some of my Android applications and other non-Android applications.

This business is mainly frequented by women of various ages. And in the waiting room, I see other customers touching their own smartphones, but I don’t know if they have their own wifi.

However, I have never been able to access his business online. The retailer's wifi key only serves me to browse and open my regular applications. So what do all these stories of "hacking" and "open wifi" that I read in this forum mean?

What he displays is probably the key to a guest wifi, not his private network, but as F16 said, that doesn’t exclude his responsibility if someone sends a threatening email to the President of the Republic from his connection; it could go very badly for him afterward.

Hello,

In the case of an open WiFi (without a password), or a WiFi where the password is intentionally shared, there is no need to hack the network since access is possible in a "normal" way.

Once connected to this merchant's network, you access the Internet using this merchant's Internet connection. If one of their visitors does illegal things online, the (gendarmerie/justice) will see this merchant's IP address, and will then approach this merchant for explanations. If the merchant is unable to provide "records" indicating who connected to their network in order to access a given site, then the merchant will be held liable. That’s why administrators of corporate networks or hotspot networks must implement authentication and log "who accesses what, and when." Some merchants, well-meaning and wanting to help their customers, have already faced legal consequences for naively opening their WiFi or giving out the password.

But let’s return to your own WiFi at home. This is a WiFi that is not supposed to be shared outside of your private circle; you have not implemented any solutions to individually authenticate who connects to your network for what purpose. Therefore, if a neighbor connects to your network and does illegal things, you will not be able to prove that it was the neighbor, and thus, you will pay in their place. It is therefore crucial to ensure that no one else but you uses your own Internet access; in fact, this seems obvious, and I find it hard to understand what you don't get about this.

As for the use of the word "hacking," I assumed that your WiFi is password-protected and that you have not shared this password with the neighbor. If the latter has managed to connect to your WiFi, then it seems that there has indeed been a hacking of your WiFi password. As already stated, it's within everyone's reach; the technique may take more or less time depending on the complexity of the WiFi password: an 8-digit password can be cracked in a few seconds, while a longer password made up of letters/numbers/symbols may take months to be hacked.

Good evening brupala,

Yes, on the day my neighbor connected, both the wifi and Bluetooth ON MY HP COMPUTER,

were activated.

And the notification appeared at the bottom right of my screen, in white letters.

The message said in French, (neighbor's phone alphanumeric ID) followed by the line below (neighbor's real first name and last name) wants to connect to (my slim PC's alphanumeric ID).

And immediately, another message appeared, in French: "allow," "block once," and "block forever."

After being very surprised, I immediately chose, with my wired mouse: "block forever."

And right away the message disappeared. Unfortunately, I didn't think to take a screenshot.

And since then, nothing from any neighbor.

I hope it was an accidental connection. It pains me to think that this neighbor deliberately wanted to connect to my PC. This man is about 40 years old.

I do not invite my neighbors into my home, especially during the covid period, especially this neighbor L.A., and so I will not accept that their electronic devices intentionally connect to my folders, my files, or my peripherals.

Of course, notifications do sometimes appear at the top right of my screen. For example, new messages from this site "comment ça marche" appear immediately at the top right of my screen, so I can read them right away.

Does my new message help you better understand my original message?

Thank you for reading me and see you soon!
