How to detect Cloudflare?

There are many ways to detect it:

emsisoft.com.		21599	IN	NS	bella.ns.cloudflare.com.
emsisoft.com.		21599	IN	NS	dom.ns.cloudflare.com.
dev.qubes-os.org.	299	IN	A	104.18.228.122

ASN AS13335 Cloudflare, Inc.
Organization Cloudflare, Inc.
Route 104.18.224.0/20
IMPORTANT: Please add only "Base Domain"

    if "community.example.com" is using Cloudflare
        add "example.com"

    if "www.example.co.uk" is using Cloudflare
        add "example.co.uk"

    if "example.net" is using Cloudflare
        add "example.net"

... to /split/cloudflare_e.txt

But the website X no longer using Cloudflare!

Are you sure? Remove it from /split/ list and add to “ex_cloudflare_users.txt".

  • Above is how Siteground-hosted(INAP;Singlehop) sites often appear to Tor visitors when timeouts/tarpitting doesn’t occur.

About "CDN FQDN list"

www.example.com
   ---> www.example.com is using CDN.

?.akamaiedge.net
   ---> subdomain of akamaiedge.net is using CDN.
   * unique hostname will be masked as "?" for privacy reason

senate.gov
   ---> base domain is using CDN.

Some websites combine other companies with the Cloudflare business model.

This is a collection of websites that ban Tor exits, other than through Cloudflare(e.g. showing access denied pages, systematic timing out connections, ...).

Website is rejecting Tor visitor

List name Description
/fqdn/attd.txt Block Tor access Split files, Everything (FQDN)
hostility.md Does NOT block Tor access Domain and Comment

  • Some news websites are lying to Tor users. You can read their website if you are not using Tor nor VPN. If you visit their website over Tor, they just say “Sorry, article not found".

  • Imunify360 is not so intelligent because it is blocking real human.

  • Some famous mail subscription service and some ISP websites are displaying “Maintenance” page if you visit them over Tor.

How can you trust their sites if they are not treating everyone equally?


About "Anti-Tor FQDN list" (attd*.txt)

www.example.com
   ---> www.example.com denied/bullied Tor visitor.

?.akamaiedge.net
   ---> subdomain of akamaiedge.net is denied Tor user.
   * unique hostname will be masked as "?" for privacy reason

senate.gov
   ---> base domain denied/harassed/challenged human who're using Tor.

If your website is on this list, you better talk with your network administrator.

But my website X no longer blocking Tor users!

Are you sure? There are two ways to remove yourself. First option is just remove it from the list and create a pull request. Second option is wait 1 year. Our system will revisit your website as a Tor user.

If you’re not blocking Tor users, you will be removed automatically.

  • If your website is using Cloudflare
  • There’s a higher chance that we receive rejection webpage from Cloudflare. Do not use cloudflare.

How to setup git

This procedure will give you a stop_cloudflare fork with a privacy-respecting configuration to do pushes with SSH over Tor using codeberg.org(“CDB”). Below procedure is designed for Linux. The first step covers Windows too, but these instructions probably need more adaptations for Windows and other platforms.

  • Linux: aptitude install git tor ssh
  • Windows: Download PortableGit from Github & run git-bash.exe
  1. Install Git, SSH(Not Windows), and Tor (if you haven’t already)
  2. Create a codeberg.org account (username “snowden” will be used for this example)
  • NOTICE: Codeberg is blocking temporary email services and some minor email providers(not temporary email).
  1. Create an SSH key pair $ ssh-keygen -t rsa -N '' -C 'snowden at codeberg' -f "$HOME"/.ssh/id_rsa_codeberg-snowden
  2. Edit $HOME/.ssh/config:
    host codeberg.org
         hostname     codeberg.org
         ForwardX11   no
         ProxyCommand connect -4 -S 127.0.0.1:9050 $(tor-resolve %h 127.0.0.1:9050) %p
    host codeberg-snowden
         IdentityFile /home/user/.ssh/id_rsa_codeberg-snowden
  1. copy "$HOME"/.ssh/id_rsa_codeberg-snowden.pub to clipboard
  2. codeberg.org > settings > SSH/GPG Keys > add key (paste from clipboard)
  3. $ firefox https://codeberg.org/crimeflare/cloudflare-tor
  4. fork it (top right corner)
  5. go to the directory you want the project to be rooted in (hereafter we’ll call it $project_root).
  6. anonymously download your fork: $ git clone git@codeberg-snowden:crimeflare/cloudflare-tor.git
  7. edit $project_root/cloudflare-tor/.git/config to include the account name and email address that will be on every commit, as well as the URL:
[user]
        email = BM-yadayadayada6fgnLfybVnCcWf25AGZcgg@bitmessage.ch
        name = snowden
[remote "origin"]
        url = git@codeberg-snowden:snowden/cloudflare-tor.git
     	fetch = +refs/heads/*:refs/remotes/origin/*
[remote "upstream"]
        url = git@codeberg-snowden:crimeflare/cloudflare-tor.git
     	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master
  1. make your first change
  2. (from $project_root) $ git add . -u -n
  3. check that the files listed are what you changed and intend to push upstream
  4. if yes: $ git add . -u
  5. $ git commit -m 'description of first change'
  6. $ git push origin master
  7. $ firefox https://codeberg.org/crimeflare/cloudflare-tor
  8. make a new pull request

 

Whenever git operates on the cloudflare-tor project, all connections to codeberg are automatically over Tor with this configuration (because the url in .git/config references the virtual host codeberg-snowden in ~/.ssh/config).

About Cloudflare base domain list

Our mission is clear - stay away from Cloudflare.

If the subdomain.example.com is cloudflared, we add example.com to the database. (subdomain.example.com is the sub-domain of example.com. Only the owner of example.com can create sub-domain)

Even if whatever.example.com is not behind cloudflare we will raise a warning, because the base domain example.com is cloudflare user.

The owner of example.com can enable Cloudflare to whatever.example.com at any time without user’s notice. It can be done from dash.cloudflare.com webpage or hitting Cloudflare API. The owner is supporting Cloudflare and this is severe security risk.

Until the owner completely stop using Cloudflare service for example.com, we do not remove example.com from the database.

There is no exception.


"amazonpayments.com"

$ getweb --headonly https://pages.amazonpayments.com/robots.txt

cf-cache-status: HIT
expect-ct: max-age=604800, report-uri="https://report-uri.cloudflare.com/cdn-cgi/beacon/expect-ct"
alt-svc: h2="cflare******.onion:443"; ma=86400; persist=1
server: cloudflare
cf-ray: XXXXXXXXXXX-YYY

If the owner moved away from cloudflare completely, you are welcome to add example.com to the “ex_cloudflare_users.txt” - after checking example.com with online tool below.

  1. Open “Is MITM?” webpage.

  2. Input gitlab.com and click Scan.

  3. Click test for detailed scan.

  4. If you got ---Finish---, the domain might stopped using Cloudflare. We’ll investigate and remove it - or not.

  • wait some days and scan again to see whether the domain is removed

Only a few Cloudflare user leave Cloudflare. False positive is uncommon.


“Cloudflare is not an option.
