How do they disable DoH? They block TLS over that port?

Thats DoT, DoH ist just a dns query over https(443)

Alright, I repeat my question, since it's almost identical: how do they block that? HTTPS starts with opening a TLS socket, how do they reliably determine that they can drop that traffic?

You don't generate a key pair to share with the client? How does that even work when you want to disable a key or set a password?

What i meant generating keys is not equal to generating certificate in the common sense of this word, it only works with randomly generated keys , passwords are not save way to encrypt data unless you can remember random sequence of characters for every client you have. If look at WireGuard protocol will get all the answares.

I got my answers, it is pretty much openvpn with a different wireprotocol and there are key pairs.

> To be clear: DoH and/or DoT would have stopped the gathering of DNS query data in this case. It's simple to set up, and it's just a smart thing to do for anyone concerned about their privacy. Actually, for most people that are not technically savvy this is definitely not an easy thing to set up, nor are they even aware that DoH/DoT exist. Unless this feature starts being turned on by default in routers and popular…

Most malicious ISPs disable DoH (ex: Verizon) so it likely wouldn’t have solved this. If you want it solved find a protocol that can be used in the libc resolver and make it ubiquitous rather than goofing around with browser defaults.

Is this confirmed? I couldn't find a source for this statement.

I don't know if Verizon is actively doing it, but since most providers that offer DoH have well-known IPs, like 8.8.8.8, 1.1.1.1, 9.9.9.9, they could easily just block traffic heading in that direction.

This is something that the average user fails to understand. One thing is saying I don't care they check on what I visit but once you aggregate enough information, it can become something of a "Big Brother". With enough DNS data I can assure you I can see when you leave to work, get back, determine the moment when you leave for vacation and no one is home, etc.

(Disclosure: I'm Thai) Especially in Thailand, where free speech is almost non-existent. Few months ago there were Twitter user who goes by the name "Anonymous" ("นิรนาม" in Thai) who have been arrested for spreading fake news and being a threat to the country. The Twitter user mainly tweets about topics subjected to lèse-majesté law. He never leave any traces, which leaves question on how officials managed to track…

But aren't all the URLs in the messages/notifications "shortened" to a t.co/. So he would have had to click on the link.

Solution for this is to tunnel the traffic through encrypted connection to servers in countries that respect persons privacy(if that is true nowadays). The easiest way is to use WireGuard, easy to set up uses only one port and have clients for many devices.

Thailand has some new and strong privacy laws: https://www.insideprivacy.com/data-privacy/thailand-passes-p...

Which have been delayed for a year due to C19.

All Thai constitutions have had strong privacy requirements, but that has never been important for what actually happens.

It's really not clear what compliance will be like. If it's anything like most things here then it'll only be if the government gets annoyed that a company will be in any danger of prosecution.

Cloudflare has a privacy policy https://developers.cloudflare.com/1.1.1.1/privacy/public-dns... Obviously, for Thai users this is a reasonable option, but I would understand why American users would not want to use Cloudflare, Google or even Quad9, as these are all US-based.

The netflow data from cloudflare, which is 0.05% of all traffic, is retained for 60 days according do the compliance report. 8.3B log entries is a lot, but I suspect that given how large market share cloudflare has, 0.05% over 60 days is also not a small data set. My intuition with probability calculus make me suspect that given normal internet usage over 60 days, a person is more likely than not to end up in cloudfl…

> a person is more likely than not to end up in cloudflares netflow log.

They are, but because this is all Cloudflare's 1.1.1.1 service does, that log only tells you that the IP address used Cloudflare's service.

So whereas this Thai data more or less says e.g. You watched Netflix between 18:40 and 19:26 and then again 21:33 to 22:09 the Cloudflare data says you own a device that uses Cloudflare's 1.1.1.1 DNS service. Maybe you can try to do some kind of activity estimate e.g. me idly browsing random web sites probably causes more DNS queries versus a SmartTV just periodically doing auto-updates when I'm asleep, but the 2000:1 dilution would make that more unreliable.

It isn't strictly nothing but it's damn close.

Just for my understanding: this wouldn't have happened if the user in question would've used a VPN and/or TOR right?

Don't get me wrong, I really don't like this in Thailand and it's absurd that you would even need something like that. As a foreigner visiting Thailand I don't feel that comfortable with my browsing habits. Usually I trust a local provider enough to just browse and not care about what I'm looking up, Thailand is not one of those places and I always use a VPN. (Mostly routed to Singapore)

Yes, it probably wouldn't happened if the user uses VPN or Tor. If VPN or Tor's setup doesn't leak DNS, at least.
