How to stop other desktop from connecting to me?

Once every few days I see this notification on my screen:

And i have no idea what this "DESKTOP-T09NIFV" is. Can i ban him from connecting to me? How does he even do that? And its appearing saying only "disconnected" never with "connected". Also i tried to disconnecting from network but its not showing up. It just appears out of nowhere sometimes and im really scared about it.

notifications - dunst

Looks like a Windows machine, that once was connected via Bluetooth. You should be able to delete it in your Bluetooth connections.

And what program is generating that notification?  FWIW, if someone was hacking into your system, they wouldn't do so in a way that'd generate an informative on-screen-display notification.

Do you have (an) external monitor(s)?

Just a couple of simple and useful tools, in case you want to look a bit more into your network traffic:

To see active connections, use something like:

ss -tpr

That should produce a list of applications that have active TCP connections, and they should all be known, or at least make sense, to you.

To search for text patterns in the network traffic to and from your computer, use something like:

sudo ngrep -d any -i <search term>
