The difference is that you need way more interaction. Expose a webserver on the internet and check how many requests you get from just bots.

You can control what you navigate and how to interact with the outside world, but you can’t control how the outside world will interact with your services.

Don’t expose anything from your local network to the internet (unless you want multiple new sysadmins in your house). Try tailscale instead.

Because I wanted to try if others URI schemas were supported instead of http / https. file:// was a valid one. Don’t worry, the day an attempt of data exfil will happen, you will not see it though your console logs.

Is this, by any chance, originated from the sub called ignore me? In that case is probably my bad because is set as the image of the channel. I was playing with lemmy in the previous version and forgot about it, sorry.

I created that channel to investigate why the lemmy instance was hanging every time there was a symbol in the URL, added that URI as icon for fun and forgot about it.

That alert appears because your browser is trying to load an image with that path, nothing dangerous or remotely exploitable, don’t worry.

Edit: I removed it so you shouldn’t see the alert anymore.

P.S. no, it’s not trying to steal anything, it’s your browser trying to load that file as an image but instead of being let’s say this url: https://beehaw.org/pictrs/image/c0e83ceb-b7e5-41b4-9b76-bfd152dd8d00.png (this sub icon) , it’s this one file:///etc/passwd so you browser is doing the request to your own file. Don’t worry, nothing got compromised.
