Intermediate cert: GlobalSign RSA OV SSL CA 2018 Root Cert: GlobalSign Root CA - R3 Both the root an intermediate certificates are correctly installed in the FF store. The certificate on this site is signed by GlobalSign nv-sa. When i surf to (my ISP) i get a SEC_ERROR_UNKNOWN_ISSUER error (which can be by passed). For those who know how, and are willing, to otherwise act in a secure way, the risk can be reduced to the point where a successful attack would be merely annoying, not devastating.I have FF Developer Edition (FF-DE v 72.0b6) and the normal FF edition side by side.Īll websites using Globalsign certificates are failing since the latest FF-DE update? That said, these risks can be mitigated by being properly cautious - not allowing Javascript or other client-side code to run, remaining aware that the page your seeing may not exactly be the page the author wrote, and so forth.įor naive users, HTTPS is valuable protection even if the website is not of a sensitive nature. If you’re using a password-protected access point without a VPN, then this is still a real risk, although it takes a little skill to pull off. If you’re using an open WiFi access point without a VPN, then this is even a low-skill attack that can be performed by anyone else within radio range of the access point. Using plain HTTP, an attacker can easily inject malicious javascript into the pages you’re viewing, alter the contents of the pages you see, etc. HTTPS protects against man-in-the-middle attacks. Personally I’ve always used but DNSCrypt-Proxy flawlessly, not even DNS-over-HTTP/2 can, yes. It has zero benefits over these, so it is not implemented.” dnscrypt-proxy will try all the configured resolvers, and use the fastest ones no matter what the protocol is.ĭNS-over-TLS is useless. Unless one of them gives you systematic issues due to your ISP blocking it, you should just leave them both enabled. But certificate management can be tricky.ĭnscrypt-proxy supports both protocols. It was explicitly designed for DNS, doesn’t allow insecure parameters, is way simpler (= reduced attack surface), and has proper padding.ĭNS-over-HTTP/2 is easier to deploy, as it can be served as a web page. “DNSCrypt is faster (over UDP, which other options don’t support) and slightly safer than DoH. It has zero benefits over these, so it is not implemented.” ends his one year old comment stating, Information is too easily abused and used against people today.Īccording to jedisct1, the developer of DNSCrypt-proxy, “DNS-over-TLS is useless. The only time https will truly work is when it is used in conjunction with encrypted DNS too. Just how would you go about correcting this? It’s easy to see how this information can be abused – what if you were buying medicine for someone else? Or perhaps it was a shared computer? Or maybe just a straight forward algorithmic error which the programmer has made. Now suppose you are going on holiday and are looking for travel insurance – do you think that the cost of the insurance will go up or down due to this information if it was shared with the insurance company? And what if you claimed to be fit and healthy – would they consider you to be dishonest due to the inferred information received via third party? Would this “dishonesty” then have a knock on affect with car insurance or property insurance or life assurance or loans or credit cards etc? They might not know what you looked at due to the https encryption but they can infer that you have some sort of medical ailment that was serious enough to need a doctor and required treatment. DNS shows that you visited Google and did a search (don’t know what was searched), visited a medical website (Google search was likely medical related), went to your doctors website (serious enough ailment to seek medical help), went to a pharmacist website and bought something (clearly need some medicine). What most people don’t realise is that you can infer quite accurately from DNS meta data even if you visit an https encrypted website.Į.g.
