Perform Secure-by-default or Woefully Insecure ‘DNS’ Queries

Description

Perform and process DNS over TLS, DNS over HTTPS, or Just Plain DNS queries using the getdns (https://getdnsapi.net/) C library.

NOTE

Requires getdns to be installed and available for compilation (no guard rails setup yet):

  • Use brew install getdns on macOS
  • Install libgetdns-dev or libgetdns-devel on debian/ubuntu (version 1.5.1 or higher)
  • Windows support is likely in 2020 since getdns moved to a cmake build system with a primary intent to make Windows a first-class citizen.

You’re going to need version 1.5.1+ of getdns for this package to install.

I’ve gotten this running on macOS and Ubuntu 16.04. For the latter I had to ensure libidn2-0-dev and libunbound-dev were installed then had to grab the 1.5.1 tarball (e.g. aria2c https://getdnsapi.net/releases/getdns-1-5-1/getdns-1.5.1.tar.gz), extract it and config/make/make install (plus ldconfig after).

TODO/WAT

I finally grok the getdns api so the package api is going to change wildly and fast. The default mode will be to perform queries using DNS over TLS but also supports UDP and TCP transports along with support for DNS over HTTPS.

Why?

Well, for starters, to help research DNS over TLS/DNS over HTTPS servers. Plus, for fun!

If you’re asking “Why DNS over TLS/HTTPS at all?” then “faux” privacy. Why “faux”? Well, something is handing your query and that something knows your IP address and what you looked for. So, you’re relying on the good faith, honest nature and technical capability of the destination server to not mess with you. I don’t trust Cloudflare or Google and am witholding judgement on Quad9 either way (they’ve been doing good things and are less “look at how cool we are” than CF is).

Also “faux” in that you’re going to be using (for DoT) a standard port (853) and a TLS session for the queries so your internet provider will know you’re doing something and the current, sorry state of SSL certificates, certificate authorities, and authoritarian companies and regimes combined means confidentiality and integrity are always kinda in question unless done super-well.

What’s Different About This vs Regular DNS?

Well, if we lookup the addresses for yahoo.com the old-fashioned way it’s cleartext UDP on the wire:

1   0.000000   10.1.10.57 → 10.1.10.200  DNS 80 Standard query 0x8af8 A yahoo.com OPT
2   0.003297  10.1.10.200 → 10.1.10.57   DNS 176 Standard query response 0x8af8 A yahoo.com A 72.30.35.10 A 98.138.219.231 A 72.30.35.9 A 98.137.246.7 A 98.138.219.232 A 98.137.246.8 OPT

I watched for port 53 UDP traffic with tshark as yahoo.com was being looked up. Notice the fast and diminuitive — and plaintext — response. (I’m fibbing a bit since I pre-loaded the local home DNS server with this query since I tested it alot before knitting this readme. My home server forwards all queries to a custom DNS over TLS server since I really don’t trust any of the providers when it comes down to it. So, in reality for me, it’s even slower than the below — at least initially).

This is the same query via DNS over TLS

It’s stupid slow, consumes more CPU and bandwidth but forces adversaries to work pretty hard to try to figure out what you’re looking for.
