An analysis of X(Twitter)'s new XChat features shows that X can probably decrypt users' messages, as it holds users' private keys on its servers

  • I mean they’re encrypted in transit. They’re just not end to end encrypted.

    Do not look at all those (proprietary) E2EE definitions to closely - you might find several that define TLS as end to end...

  • I'm trying, but they keep forcing it into devices I already own and even with turning it off in the settings sometimes it gets turned back on during updates. At least avoiding the X/shitter bot is easy enough, but the rest are just as invasive.

    Out of curiosity what devices are giving you these issues? I may know of some alternatives depending.

    Anything with a web browser. Work computers. Phone. Have to turn off the AI crap on all of those manually after they were added in updates.

    Don't really believe turning off the settings keeps them from farming data either, since they constantly lie about what data they collect and use for training.

    I mean TLS is also encryption in transit, it’s in the name. And it would sorta be end to end if you’re terminating TLS at the end you’re trying to talk to.

    If anyone except you has the private key, then your private messages are not private.

  • If anyone except you has the private key, then your private messages are not private.

    To extend this, that includes YOU giving your key to another application to decrypt those messages.

    For example if you use an app or browser extension, that app or browser extension has access to that key. Additionally the browser itself or operating system had access to the key.

    Now they may be fully audited. They may have a great reputation. You may trust them. But they are part of the decryption (and if sending encryption) process.

    It's a chain of trust, you have to trust the whole chain.

    For web browser's, check librewolf or brave, I would lean further towards librewolf just because it's oss which is something I value.

    For search engines, we're in a weird spot right now because Microsoft is restricting the use of Bing's search API, but duck duck go is good, and ecosia as well, but they both may be in a rough spot soon.

    Work computer you can't do much other than ask your supervisor to ask about moving away from ai stuff, all you can do directly is limit your personal information on your work station.

    For phones, If you have apple, sorry, if not, you could look into changing the operating system on it to something like e/os or graphene os, they are both operating systems that are focused on privacy and security.

    If you need anymore information about my recommendations, I am happy to help.

    Thats the problem. Say, I'm offering you a cloud drive and tell you "your data is end to end encrypted". You sync data from your PC to my server and from my server to your mobile phone. Would that mean

    1. That everything between your devices is encrypted (=I can't see what you're saving, neither can "the state", hackers,...)or
    2. That your data is encrypted in transit, but is saved unencrypted on my server (which means everyone with access to my server can see your data) or
    3. It's encrypted in transit and also on my server, but the keys are also ony server, so that everyone with access to my server can in theory decrypt everything and access everything?

    1 is what you want, 2 and 3 are often what you get...

    It’s not that I disagree with you on principle, I think you’re just kinda mixing up scenarios here, and the purpose of E2EE. E2EE refers to in transit data specifically. #1 should never be where your mind goes because E2EE does not imply your data will be encrypted at rest at the destination, that’s not what it’s for. E2EE is a critical factor when the untrusted facilitator party is between you and your intended recipient, not the recipient themselves.

    Like in your scenario of a “cloud drive”, E2EE would not be a selling point of that service. The term you’re looking for in that scenario is “zero access encryption”.

    Like you’re correct that E2EE does not imply that data stored in the cloud is encrypted at rest, but that’s because it isn’t meant to. Like this isn’t a dirty marketing trick. E2EE just needs to do what it says on the tin, which this X chat does not because they in order for it to be E2EE, it needs to be the case that only the recipient can decrypt it.

    On my desktop (windiws) I use Libre wolf for most things, but Firefox for YouTube because I'm signed in with my Google account for subs and stuff. I use FF for only youtube on the PC though, and yeah open source few.

    I use Firefox on my phone as I don't think Librewolf has a mobile version.

    I use duck duck on all the browsers, but it is going downhill.

    At some point I will switch desktop to Linux, just haven't come up with a plan for backing up data to do a smooth transition. Keep putting it off when life stuff come up.

    And yet people still keep using Twatter like it's the only thing that has ever existed since the dawn of the internet. At this point, you deserve to get wrecked for still using this platform.

    If a corporate entity made it and hosts it, and it isn't foss, don't chat on it.

    There is another layer here. If you or the person you're talking to are using an entirely unmodified android or apple phone, you don't have any privacy even if you're on TOR connected to an encrypted xmpp chat. Your entire existence is backdoored. The entire OS speaks back to its maker, especially that keyboard.

    The third paragraph contradicts your other point. You define E2EE in two wildly different ways.

    The chat messages are most likely stored on an intermediary server, which would qualify for the same loophole you pointed out in the cloud storage example.

  • The third paragraph contradicts your other point. You define E2EE in two wildly different ways.

    The chat messages are most likely stored on an intermediary server, which would qualify for the same loophole you pointed out in the cloud storage example.

    No it doesn’t, and I defined E2EE exactly one way. E2EE stands for “End to end encryption”, which means it’s encrypted at one end, decrypted at the other end, and not in the middle.

    It doesn’t matter if they store a copy of your message on an intermediary server, the keyword there is intermediary. They are not the recipient, so they should not have the ability to decrypt the content of the message, only the recipient should. If they are able to decrypt your message, despite not being the recipient, it’s not E2EE.

    A cloud drive is an entirely different case because the cloud drive is not an intermediary. They literally are the second E in E2EE. A cloud drive can have the ability to decrypt your data and still be E2EE because they are the recipient. You both seem to be under the impression that a cloud drive is an “intermediary” between your devices but it’s not. It’s a destination.

    To explain it a bit simpler, imagine we’re in elementary school sitting at our desks and you’re sitting two desks away from me with one person between us:

    E2EE = I encrypt my note with a simple cipher that I shared with you and only you before class. I pass my note to the kid between us to pass to you. He can’t read the note, and if he writes down a copy of my note before passing it to you it doesn’t matter because he still won’t be able to read it because he’s doesn’t have the cipher because he’s not the recipient, you are. He passes you the note and you can do whatever you want with it, including decrypting it, because you know the cipher. All the E2EE has done is ensured the kid in the middle can’t read the note. It has nothing to do with whether or not you can read the note.

    Zero Access Encryption = I encrypt my note with a cipher that only I know. The kid in the middle can’t read this note, and neither can you. Then I use E2EE to encrypt that with a different cipher, the one that you do know, and hand the note to the kid in the middle to hand to you. The kid in the middle can’t read the note, and neither can you.

    It's a chain of trust, you have to trust the whole chain.

    Including the entire other side of the conversation. E2EE in a group chat still exposes the group chat if one participant shares their own key (or the chats themselves) with something insecure. Obviously any participant can copy and paste things, archive/log/screenshot things. It can all be automated, too.

    Take, for example, iMessage. We have pretty good confidence that Apple can't read your chats when you have configured it correctly: E2EE, no iCloud archiving of the chats, no backups of the keys. But do you trust that the other side of the conversation has done the exact same thing correctly?

    Or take for example the stupid case of senior American military officials accidentally adding a prominent journalist to their war plans signal chat. It's not a technical failure of signal's encryption, but a mistake by one of the participants inviting the wrong person, who then published the chat to the world.

    Thanks for sharing this, it is an interesting read (though an additional comment about what this about would have been helpful). I want to say I am glad I do not use either of these services but Yandex implementation seems so bad that it does not matter, as any app could receive their data

    It’s funny how the article asks the question, but completely fails to answer it. About 15 years ago, Nvidia discovered there was a demand for compute in datacenters that could be met with powerful GPU’s, and they were quick to respond to it, and they had the resources to focus on it strongly, because of their huge success and high profitability in the GPU market. AMD also saw the market, and wanted to pursue it, but just over a decade ago where it began to clearly show the high potential for profitability, AMD was near bankrupt, and was very hard pressed to finance developments on GPU and compute in datacenters. AMD really tried the best they could, and was moderately successful from a technology perspective, but Nvidia already had a head start, and the proprietary development system CUDA was already an established standard that was very hard to penetrate. Intel simply fumbled the ball from start to finish. After a decade of trying to push ARM down from having the mobile crown by far, investing billions or actually the equivalent of ARM’s total revenue. They never managed to catch up to ARM despite they had the better production process at the time. This was the main focus of Intel, and Intel believed that GPU would never be more than a niche product. So when intel tried to compete on compute for datacenters, they tried to do it with X86 chips, One of their most bold efforts was to build a monstrosity of a cluster of Celeron chips, which of course performed laughably bad compared to Nvidia! Because as it turns out, the way forward at least for now, is indeed the massively parralel compute capability of a GPU, which Nvidia has refined for decades, only with (inferior) competition from AMD. But despite the lack of competition, Nvidia did not slow down, in fact with increased profits, they only grew bolder in their efforts. Making it even harder to catch up. Now AMD has had more money to compete for a while, and they do have some decent compute units, but Nvidia remains ahead and the CUDA problem is still there, so for AMD to really compete with Nvidia, they have to be better to attract customers. That’s a very tall order against Nvidia that simply seems to never stop progressing. So the only other option for AMD is to sell a bit cheaper. Which I suppose they have to. AMD and Intel were the obvious competitors, everybody else is coming from even further behind. But if I had to make a bet, it would be on Huawei. Huawei has some crazy good developers, and Trump is basically forcing them to figure it out themselves, because he is blocking Huawei and China in general from using both AMD and Nvidia AI chips. And the chips will probably be made by Chinese SMIC, because they are also prevented from using advanced production in the west, most notably TSMC. China will prevail, because it’s become a national project, of both prestige and necessity, and they have a massive talent mass and resources, so nothing can stop it now. IMO USA would clearly have been better off allowing China to use American chips. Now China will soon compete directly on both production and design too.

    Soon this all will be much easier. From 12 of September we’re going into a new world of EU Data Act that forces all companies to allow third parties to communicate with iot devices. Which a car is. So soon Mazda will need to provide those APIs in an official way.
