Gmail Goes HTTPS Only For All Connections 141

Trailrunner7 (1100399) writes "Perhaps no company has been as vocal with its feelings about the revelations about the NSA's collection methods as Google has, and the company has been making a series of changes to its infrastructure in recent months to make it more difficult for adversaries to snoop on users' sessions. The biggest of those changes landed Thursday when the company switched its Gmail service to HTTPS only, enforcing SSL encryption on all Gmail connections. The change is a significant one, especially given the fact that Google also has encrypted all of the links between its data centers. Those two modifications mean that Gmail messages are encrypted from the time they leave a user's machine to the time they leave Google's infrastructure. This makes life much more difficult for anyone—including the NSA–who is trying to snoop on those Gmail sessions." GMail also does TLS for SMTP, but regrettably Talk (what's left of it) does not do TLS for XMPP server-to-server connections, effectively forcing XMPP server admins to lower their security if they want to federate with Google.

        I don't know if you've been keeping up. But people fully EXPECT the NSA to be upto nasty secret snooping habits. That is actually the minor part of the story that caused the outrage. The more dangerous fact is that the NSA can demand companies or individuals turn over data to them and impose a gag order thus forcing them to keep it secret.

        So AC is right in this case. Just more lip service. Encryption on your own servers is the only way to remain relatively protected.

          I agree that the latter IS a big problem. But I don't agree that it's the ONLY problem, or the only BIG one.

          National Security Letters are still relatively narrow compared to what the NSA did. They also tapped the fibers Google and others used to communicate with each other, and used these taps to snoop everything that went across them, without Google's knowledge.

          I encountered a Google engineer with job responsibilities related to that at a conference last year, and he was LIVID. They'd tapped fibers OWNED BY GOOGLE - trespassing and damaging them (aong with Google's credibility) in the process - with no letters, warrants, wink-wink-nudge-nudge, or what-have-you. Google has since been installing encryption thorughout it's network - not just where it leaves the building, but even from rack to rack.

          Maybe they're still stuck disclosing SOME stuff. But at least they're trying to know what it is, do their best to minimize it (and protect their model), and avoid inadvertently firehosing EVERYTHING into the maw of the NSA.

        Google has their own intermediate CA, which is a subsidiary of GeoTrust. Given that such an intermediate could issue certs for the global internet, GeoTrust probable provides a "managed PKI" service where they retain control of the intermediate so that it will only issue certs for Google-controlled domains.

        In such a situation, GeoTrust could be compelled to issue certs using Google's intermediate CA without Google's knowledge.

        Alternatively, if Google maintained control of the intermediate, the NSA would need to compel Google to generate certs for them from their own intermediate. However, if the NSA went to GeoTrust and demanded that they generate an intermediate CA with all the same details (CN, O, OU, etc.) as the Google one, the NSA could generate certs for Google without Google knowing.

          Of course it matters. The NSA is trying to spy on everyone all the time, and this means they will have to do far more to target individual Gmail users instead of just hoovering it all up. That's the goal, to make mass surveillance impossible or at least extremely costly. It doesn't have to be perfect to do a lot of good.

      Ultimately, encryption is meaningless. If the NSA (or any other governmental agency) wants something, they will get it.

      Even if you invent some suoer-duoer-impossible-to-crack encryption, they will simply go to a secret court (that is accountable to no one) and get a secret order, that you must comply with and that you aren't allowed to talk about under penalty of going to prison, on the grounds of NATIONAL SECURITY.

      Until *THAT* problem is addressed, encryption is meaningless.

      • That would be a considerable extra step for NSA to comply with. If your data is unencrypted, they merely need to scrape the data and away they go- easy mass surveillance of any number of 100's of millions of people.

                You really need to read the whole Lavabit story. Basically, the government was able to convince the court that the combination of Lavabit's security architecture and the company's early stonewalling demonstrated that the only way to be sure they got all of the data the court had ordered Lavabit to hand over was to require the keys. Had Lavabit complied initially and just handed over the requested data the question of keys would never have come up.

                That may seem like a subtle distinction, but it's not. The court never said that the government has a general right to demand keys, it just said that in that particular case there were factors which meant that merely asking for the data was not going to work, and that, therefore, the government could demand the key.

                In Google's case, if the government asks -- through correct legal channels and with an appropriately-specific request -- for your e-mail, Google can and will simply comply with the request, which means that the government has no need to get keys. The only reason the government would ask for keys is in order to obtain the ability to do mass surveillance which cannot be justified Constitutionally -- and Google has the legal and technical resources to make that argument and to appeal it to the highest level.

      Google may be many things, but at least they aren't doing it behind your back. Each service's ToS clearly say what they do and don't do with your data when you are on their domains.

      You can opt out of using Google's services. You cannot opt out of your government.

      If showing you ads is like targeting your for a Hellfire drone missile strike, then sure. To me that fails the moral equivalence test.

  • Weak SMTP SSL (Score:5, Insightful)

    by Anonymous Coward on Thursday March 20, 2014 @02:37PM (#46537457)

    Sure they use SSL on their SMTP servers, but when testing it using checktls.com I see that they use RC4-SHA, not a Perfect Forward Secrecy algorithm like Yahoo is now using (DHE-RSA-CAMELLIA256-SHA). If NSA were to get a copy of Google's private key, they could decrypt all of the traffic. So to me, no PFS is the same as no SSL.

        Your statement is true if and only if both sides of the connection use Perfect Forward Secrecy.

        If PFS is not supported by one or both sides, they revert to RSA key exchange which does use the server's RSA key to encrypt the session key. If the server's private key is compromised any non-PFS traffic that was logged in the past could be decrypted.

        The AC above says that the connection between checktls.com and Gmail is made using RC4-SHA -- in that case, no Perfect Forward Secrecy is being used and the connecti

      That depends on the cipher preferences of the client (that is, the system sending mail to Gmail). In my case, connections from my server to Gmail's SMTP servers are made using ECDHE-RSA-AES128-GCM-SHA256.

      Connections from other services depend on how they're configured. Geocaching.com's outgoing mail server sends mail to Gmail using ECDHE-RSA-RC4-SHA.

      Google has been doing this for a long time.

      The article briefly mentions this, but does anyone have any additional detail? Are they using opportunistic TLS on SMTP connections?

      Yes.

      Depending on what ciphers are supported by the remote system, different ciphersuites will be supported. CheckTLS.com will only connect with RC4-SHA, but my server connects with ECDHE-RSA-AES128-GCM-SHA256. Your mileage may vary.

    • If your side does not support TLSv1.2, then Google favors RC4 cipher to thwart BEAST vulnerability. There is only one RC4 cipher that brings PFS: ECDHE-RSA-RC4-SHA. It uses Ellipitic curve cryptography. If you do not support it, nor you support TLSv1.2, you will not get PFS from Google.

      The goal is to avoid BEAST, but RC4 is weak, and PFS is highly desirable.

    effectively forcing XMPP server admins to lower their security if they want to federate with Google

    Just for the Google server, if you use a proper XMPP server (like Prosody, for example).

    Beware that many servers on the XMPP network use self-signed or invalid certificates, or even don't support TLS at all (such as gmail.com and all Google-hosted domains). It is possible to make exceptions like this:

    -- These hosts are allowed to authenticate via weaker mechanisms, such as dialback:
    s2s_insecure_domains = { "gmail.com" }

    [Server-to-server XMPP [prosody.im]]

    XMPP server operators are pushing for a wholly encrypted XMPP network [github.com] with several test-days, where they'll be flipping the switch to allow only encrypted communication, and the final switch to disallow unencrypted communication on May 19, 2014.
    It's going to include SSLv3, unfortunately, but we'll get there.

    Gmail messages are encrypted from the time they leave a user's machine to the time they leave Google's infrastructure.

    Horseshit. The message is not encrypted. It is cleartext travelling over encrypted channels. It is on their machines in the clear, which enables them to do things for you, like search and filter, and against you, like profiling you and anyone who sends you email.

  • I seem to remember hearing they had already cracked SSL among all of the recent revelations.

    Either way, this is obviously a PR move. It should give nobody any high hope for Google's intentions...

  • You know, if I didn't know better, I'd think someone did this on purpose... right now the fortune at the bottom is:

    Today is a good day for information-gathering. Read someone else's mail file./quote.

  • Why would anyone still be doing this? They wont be supporting this really soon now, so everyone should have moved on by now.
