I don't know how effective VPNs are over a public WiFi network, but I do know it stopped Spectrum from sending me "you are downloading copyrighted material, stop it" emails once I started using one. Fuck Spectrum, I don't have them anymore, but that seems like a good enough reason to keep using one in certain circumstances.

On public WiFi I just vpn into my home network. The issue with public WiFi is that it can be sniffed by anyone in range since there is generally no encryption.

Although pretty much everything we do is over tls these days, and DoH helps protect against even dns sniffing. There's still at least some risk to working in the clear over a public WiFi network. At least in information gathering, what bank you use, etc.

But, there's no real benefit in using a paid vpn over one you own unless you're downloading illegal content, want to watch another Netflix region, or are in a country with heavy Internet monitoring/filtering.

With TLS and DoH, how is your bank and other information leaked?

He said "which bank", which could be determined by the sniffing DNS requests, or seeing which IPs his computer is connecting to.

Not a breach of his personal information (assuming the bank that he's using and the client he's using after putting everything in TLS properly).

But with DoH you can’t sniff the DNS, that’s the whole point.

[–] r00ty@kbin.life 7 points 1 month ago (1 children)

But you can see the ip address, which will id the bank. They can derive other information by ip addresses or leaked data and there's still things using unencrypted connections even today. I generally just connect to my home vpn so at least it's inly my isp spying on me.

Generally you can also read the SNI.

I think this is one of the things that ech is meant to solve. But ech/esni is still not widespread on smaller sites yet I think.

[–] phillipp@discuss.tchncs.de 1 points 1 month ago

You actually still can. Have a look at DNS fingerprinting

[–] whydudothatdrcrane@lemmy.ml 10 points 1 month ago (1 children)

Possibly the domain is visible with a traffic monitoring tool. Everything else is between you and the bank via HTTPS. Having said that, whatever is not over https is visible to whoever sits on the same network as yourself.

Importantly, you probably don’t know what all is encrypted in every app you use on your phone, so it’s best practice to encrypt the transport.

I experienced the same with Cox Internet.

All ISPs are legally obligated to forward that shit to you. The alerts are not from spectrum, they're just relaying the information.

Right now, copyright owners do not have legal permission to find out who you are directly without a court order. They would only seek that information if they were planning to file a lawsuit.

Media companies know, from the Napster incident, that such actions can backfire stupendously. It's rare that they even bother anymore. I can go into detail on why, but I'll leave it out for brevity.

So they send the notice to your ISP, who is legally obligated to match the information on the notice to the subscriber and forward the notice to you.

For many, this goes to an ISP provided mailbox, which most people ignore the existence of it. Clearly spectrum operates differently.

The notices are from copyright holders who have no idea who you are, and can't determine that information unless they intend to sue you. So those can be, for the most part, ignored.

It's not your ISPs fault that you got those. They couldn't give a shit less about what you do on their service, or what you download. They just want you to pay your bill every month and keep the gravy train rolling.

[–] FlyingSquid@lemmy.world 3 points 1 month ago (1 children)

I'm saying fuck Spectrum for other reasons. Either way, there's less of a trail.

[–] MystikIncarnate@lemmy.ca 2 points 1 month ago (1 children)

Fair enough. I haven't used spectrum, so I have no opinion. I'm not in the right country to subscribe to their service, so there's that.

Have a good day.

[–] FlyingSquid@lemmy.world 2 points 1 month ago

Spectrum is a total shit ISP that does shady shit constantly, while being owned by a massive corporation run by a Trump supporter and unfortunately is the only option people have in a lot of places in the U.S.

Anyway, good talk. You have a good day too!
