This is an article written by telegram’s founder and CEO Pavel Durov in 2019 on “Why whatsapp will never be secure”. Your thoughts?

  • Sure, fuck WhatsApp, but Telegram isn’t even end-to-end encrypted most of the time. Their group chats never are, and their “secret chat” encryption for non-group chats must be explicitly enabled and hardly ever is because it disables some features. And when it is encrypted, it’s with some dubious nonstandard cryptography.

    It’s also pseudo open source; they do publish source code once in a while but it never corresponds to the binaries that nearly everyone actually uses.

    And the audacity to talk about metadata when Telegram accounts still require a phone number today (as they did five years ago when this post was written) is just… 🤯

    State-sponsored exploits against WhatsApp might be more common than against Telegram, or at least we hear about them more, but it’s not because the app is more vulnerable: it’s because governments don’t need to compromise the endpoint to read your Telegram messages: they can just add a new device to your account with an SMS and see everything.

    (╯° °)╯︵ ┻━┻

    Anything claiming to prioritize privacy yet asking for your phone number (Telegram, WhatsApp, Signal, …) is a farce.

  • What a load of hipocrisy. The dude uses unauthenticated DH for his apps “secret chats”, which a bored student with a laptop can MITM in seconds. Other chats use just TLS, meaning they get to read EVERYTHING.

    Use Signal, people.

      • It’s been a while since I looked into it, and things might have changed since then, but some stuff off the top of my head:

        • Messages are stored on the server, not on the device
        • end-to-end encryption not enabled by default
        • uses proprietary encryption, making security audits difficult

        Apart from that it’s somewhat politically questionable, based in Dubai (I think), with dubious financial backing and Russian developers. Because it’s closed source and the encryption is proprietary, there’s no way of knowing how much info it leaks.

          Yes, pretty much necessary to provide multidevice support

          end-to-end encryption not enabled by default

          True that and telegram sucks big here, but I donth think e2ee can be enabled in a feasible way for multiple devices.

          uses proprietary encryption, making security audits difficult

          The MTProto isnt open source but its fully documented, there have been security audits on it.

          dubious financial backing

          No. Pavel Durov have always said since starting he paid for telegram’s servers from his pocket, in recent years telegram has started monetisation programs to cover its costs.

          Russian developers

          The founders were born in Russia, but they now have dual citizenship of UAE and France. If you are talking about politically questionable, even signal have been accused of having backdoors for CIA.

          • Telegram is a shell company and only offers mediocre, opt-in encryption. The thing I like most about them is their support for 3rd party clients.
            I have to use their service for some contacts same as with WhatsApp but I would prefer more secure and privacy friendly alternatives.

            • You obviously haven’t seen the charts of the metadata that WhatsApp collects. And we know how anti-consuner, adversarial and anti-privacy Facebook is overall with their tracking pixels, ghost profiles, etc.

              Telegram at least doesn’t have the FB dataset. FB knows about me, though I’ve never once in my life been on their website or used anything related to them. Not once. The first I heard of FB I saw immediately the privacy problem with them, and made sure to never have anything to do with them. But they know about me from other peoe posting pics and such, which they then correlate with sites I’ve been on that have tracking pixels. WhatsApp ads a metric shitton of metadata to that pile, with date, time, location, duration of conversations, businesses you’re near at the time, their operating hours, etc, etc. They have a massive, constantly growing dataset, which they can easily correlate elements.

              WhatsApp may be encrypted, but I trust Zuck so little that I wouldn’t doubt they capture keystrokes in app before the message is sent. They have the capability as was shown in a recent research article (though no evidence of it happening).

              Id rather not use Telegram, but it’s far lesser of the two evils. I’m trying to get folks to other apps. Signal doesn’t sell, SimpleX isn’t quite ready, I think Wire has the same stored encryption key issue, though I may be mistaken (I’m not fully clear how it’s managed).

    • They tell whatever they want until their claims can be validated with the source code. If we take it for granted that they use an original, unmodified version of the signal protocol programming libraries, there are still multiple questions:

      • how often do they update the version they use
      • what are they doing with the messages after local decryption (receiving), and before encryption (sending)
      • how are they storing the secret keys used for encryption, and what exactly are they doing with it in the code

      Any of these questions could reveal problems that would invalidate any security that is added by using the signal protocol. Like if they use an outdated version of the programming library that has a known vulnerability, if they analyze the messages in their plain data form, or on the UI, or the keypresses as you type them, or if they are mishandling your encryption keys by sending them or a part of them to wherever
