      I wish all the major affected sites would prominently post this disclosure – positive or negative – on their landing pages.

      Thank you!

        NowSecure (https://www.nowsecure.com/) is also using CloudFlare. I see the big red notification box on their home page…

        Woody, can you post a more specific link? I can’t find the list of affected sites on NowSecure.

          I thought it would be easy to find a definitive list of leaky sites, but nuthin’s easy on the web…

          This site seems to be the most thorough: http://cloudflarelistcheck.abal.moe/

            Woody! Thanks for that checker!

            Here’s a list of sites that use Cloudflare, but doesn’t necessarily mean they leaked.  But sometimes better to be safe … it’s a long list, butyou can use your browser’s “Find” tool to search the list for site domains that you may use.

              This is not the full list. Far away from that. Hundreds of thousands of sites use CloudFlare. The Alexa top 10000 is just a fraction of that.

              “Cloudflare has always terminated SSL connections through an isolated instance of NGINX that was not affected by this bug.” so if you always used https://yourcloudflarehostedsite.com, you should not worry.

              However if you only typed “yourcloudflarehostedsite.com” in the address bar, browsers think you mean http://yourcloudflarehostedsite.com, and the redirection to https is made by CloudFlare. In this case, you might be affected.

              Check out https://rosettacode.org/wiki/Rosetta_Code, this is how every site using CloudFlare should look like now: they should all have a big red notification bar.

            I noticed that Patreon.com comes up positive in that checker.

      Rest assured Woody, confidence is high on AskWoody. Thanks for the heads up!

      Honesty goes a long way 🙂

      thanks for doing it right, Woody.

      unfortunate that the bad actors take advantage of the conscientious users on the swiss cheese interweb. kinda like real life in the modern world…

      Martin Brinkmann has a discussion of two browser extensions — one for Firefox, the other for Chrome – called CloudBleed. CloudBleed scans your browsing history and tell you if you’ve ventured onto a leaky site.

      Give it a try. See this ghacks article.

        The Firefox extension took seconds to install and check. I got 12 results, but there wasn’t anything with an account, which is worth knowing anyway.

          In Firefox, I use AdBloc Plus (turned off on AskWoody), NoScript, and Disconnect. Plus I run TrendMicro on my Macs.
          Mine has turned up clean every time

        I saw Uber and Yelp on a Cloudflare related list, so if you only use these from mobile, you may want to change your passwords for them.  The desktop browser plugin won’t see your mobile account use.

        If you have deleted your browser history, the plugin can also check your bookmarks instead.

        But if like me you use multiple browsers including Edge, and delete some history, I found another way.

        I also use CCleaner to preserve my “good” cookies for sites with accounts.  The CCleaner cookie “whitelist” makes a good list to check with with the leak checker you listed here: http://cloudflarelistcheck.abal.moe/

      I use NoScript & AdBlockPlus; usually to reach a site (like AskWoody), I temporarily allow the site I go to under NoScript. Have some hits, but I only have accounts on 2 sites. For Medium, I had to change my Twitter password, since I sign in with it.

      Bought a refurbished Windows 10 64-bit, currently updated to 22H2. Have broke the AC adapter cord going to the 8.1 machine, but before that, coaxed it into charging. Need to buy new adapter if wish to continue using it.
