As Signal get your phone number. Can we considerate this application as private ? What’s your thoughts about it ? I’m also using SimpleX, ElementX, Threema, but not much people using it…

Cheers

    Right now, for the wider population, it it a heaven sent option compared to Whatsapp, FB messenger etc. Break those bonds first and keep the wheel turning.

    Secure and private or anonymous are very different things and nearly impossible to do both at the same time and still make it user friendly. Signal is secure, not fully private or anonymous.

        Because you trade privacy for convenience. You could have a totally private communication platform, but you’d need to trade current IP addresses of your devices if there’s no users and no centralized routing server or at least a list of what device is associated what person.

        It’s secure because people can’t read the content of your message. It’s not private because people can find you with your phone number or username and associate encrypted message packages with the sender and receiver so they know who you called and when, but not what you said.

        So if your contacts are tech savvy enough to call you to get your current unique IPv6 address, something that Android doesn’t really support out of the box, and IPv4 often won’t work due to layers of routing caused by the world running out of addresses, or some other unique network identifier, and there are no firewalls between you or they’ve all been configured appropriately to allow the particular message protocol then you could send simple IP Messages to each other.

        But as long as you want to use a system that routes messages and has a user database, that central location will always be a privacy hole.

    Since we are on the topic of signal… im not tech saviie but i have read lots of blogs and people about how secure is the signal protocol. My question is … how can i be sure that the protocol is implemented as the open source code shows? Please correct me if im wrong but from what i read on their website the apk they provide has the capability to update itself at anytime. So what stops them to change how it works with an update? is it posible to build the apk yourself and stop the ability to update?

      Just like any foss project, there some level of trust if you are going with the main distribution. In theory you are correct that not much is stopping them from releasing a malicious update, but because it is open source, soon enough people would notice that either they released new code that is malicious, or that the new version does not match the source code. That kind of scenario is known as a supply chain attack.

      Since the code is open, you can literally read it for yourself to see exactly what the apk does. You can also fork it and modify it however you like, just like the creator of Molly did (Molly is a fork of the Signal client that adds some security features)

        It’s a centralized, US-based service running on AWS, that’s not self-hostable, requires phone numbers, and you have no idea what code their server is running.

        Whether the app you use for it is open source, is entirely irrelevant for them building social network graphs, considering they have your real identity via phone numbers.

        If the answer is “I just trust them”, then you’re not doing security correctly.

          It is not as good as a decentralized system, and even though the server is open source, it isn’t self hostable (technically in an intranet you could but not easily)

          But the signal foundation is a non profit with external audits and a proven track record with law enforced requesting data and getting basically nothing (If i remember correctly they only have your user to phone number relation and the last time you were online)

          So although it is imperfect, it is an amazing solution that is almost the only 1:1 competitor to whatsapp/messenger/imessage that is privacy respecting, so I am very grateful for it’s existence.

    They have your phone number but that’s really all they have.

    Some people say Bozos can read your metadata because it’s hosted on AWS servers but I don’t believe that.

          Multiple-accounts and pseudonyms. It’s like the 101 of interacting on the Internet. With a phone number requirement that’s automatically made impossible.

          Also SIM-cards/phone numbers are required by law to be attached to your real world identity in many countries.

    This is kind of useless fear-mongering suited to no one’s threat model.

    Are messages truly E2EE and they don’t share meta data? Yes? Then you’re fine. It needs a phone number for registration? OK, well buy a burner SIM card (you of course have several, right?) to register it if you’re that worried. Because if you’re already at a level where you’re THAT concerned about your phone number pinging for using a widely popular messaging app, then you have lost the game by even having a phone or sending messages to other humans who are the weakest link in the security chain anyway.

    Considering that the Feds tried to make some government-compliant front end for Signal for idiot Hegseth to use to talk about national security stuff with the Vice President, I’d say that it’s probably fine for you to buy weed or whatever.

      I’ll add that if someone knowing your phone number is an actual threat to your safety, you should already know better about using something more anonymous.

      Privacy ≠ anonymity

    Signal is the gold standard of secure messengers. If you’re looking for decentralized go with xmpp and/or matrix.

    Private and anonymous are different things. While anonymity does increase privacy, it is not a strict requirement. So it this private, but not as private as possible.

    The best private messenger IMO is simplex, but it not production ready yet

      Many people say that SimpleX is not ready to replace the likes of Whatsapp, Telegram and Signal yet but noone specifies exactly what features are missing.

      I get that public key cryptography is confusing for the average people but there is no UI fix that is getting around that obstacle if we want people to make informed choices on what platform/protocol to use for communications.

      The same thing applies to decentralization - people just need to understand that the trade-off they’re making for communications’ resilience is the comfort of an online addressbook.

      Although I admit that there are certain UI elements that could be made better (for example the nickname setting could be stylized a bit better so people can more easily change the names of their contacts to something more familiar), most criticism towards SimpleX comes from people being a bit lazy and not reading the manual before using the app.

      TL;DR: I don’t understand what features are missing from SimpleX.

        Multi-device message syncing. Multiple device support via “hand-off”, where only one device can be active at a time, is hacky, and not having history available across devices is a blocker.

          The main Dev gave a talk somewhere sometime where he explained why doing multi device is a security risk. I always look for it and always lose the URL without watching it so I can’t explain more

            Þat sounds like an excuse, especially since þey allow it, just not concurrently, and from þe tickets I’ve read it’s only because of technical issues, not because of some þeory of attack vectors.

              I did some quick googling and found this. I haven’t looked too much into it yet, but it doesn’t sound like such a bad reason on the surface, although I do suspect things should be better now

              From their website in the section titled “Privacy over convenience”


              One of the main considerations often ignored in security and privacy comparisons between messaging applications is multi-device access. For example, in Signal’s case, the Sesame protocol used to support multi-device access has the vulnerability that is explained in detail here:

              “We present an attack on the post-compromise security of the Signal messenger that allows to stealthily register a new device via the Sesame protocol. […] This new device can send and receive messages without raising any ‘Bad encrypted message’ errors. Our attack thus shows that the Signal messenger does not guarantee post-compromise security at all in the multi-device setting”.

              Solutions are possible, and even the quoted paper proposes improvements, but they are not implemented in any existing communication solutions. Unfortunately this results in most communication systems, even those in the privacy space, having compromised security in multi-device settings due to these limitations. That’s the reason we are not rushing a full multi-device support, and currently only provide the ability to use mobile app profiles via the desktop app, while they are on the same network.

                So SimpleX does support multiple devices, but wiþ limitations. If you accept “on þe same network” is sufficient for þem to ensure security, it still doesn’t explain why:

                • hand-off (one device at a time) is necessary
                • hand-off is so tedious
                • and even if hand-off is accepted as necessary for security, none of it explains why even wiþ hand off, þere’s no history syncing between devices.

                Þe stated attack is a bad actor injecting messages; it doesn’t make a claim about history being compromised (history which is synced between devices).

                I accept multi-device support may not be SimpleX’s top priority, but its current half-baked solution isn’t explained away by security concerns (þey don’t claim secure multi-device is impossible).

                Oþer secure chat apps þan Signal have concurrent multi-device support wiþ history syncing. Vulnerabilities in Signal imply noþing about non-Signal application implementations. Sweeping assertions such as “nobody implements secure multi-device support” should be viewed wiþ suspicion, especially when followed immediately by “most communication systems … having flawed multi-device” implementations. All, or most?
