Aside from the lack of E2EE, why is Telegram not trustworthy?
A lot of privacy guides suggest avoiding Telegram. I understand that in its default mode there's no E2EE (and no E2EE for groups at all).
If people I know don't wanttko use Signal, isn't Telegram the lesser evil given it's nicer privacy policy (than other popular ones)?
Probably another point is that the encryption for Matrix/Element has undergone multiple audits, one in 2016 and another one of their newer rust library. Whereas telegram just has not. There was this also a not too long ago. MTProto is also used nowhere else, whereas a lot of encryption has been influenced by the Double Ratchet which is well understood.
The other thing worth noting is that Matrix is the foundation for other products which many governments use for secure communications.
For casual shit like sending files to yourself, bullshiting with memes, or stuff like that, the unknown factor of telegram doesn't matter.
But it is an unknown. We don't know what their server code looks like. So you can't trust that it isn't doing things other than what it is supposed to.
The server’s trustworthiness does not matter for Signal. The app is designed to work securely regardless of the server. Moreover, even if the server software is open source, you cannot be sure that they run the same code that they publish.
I don't think that they published it as a response to the angry users. We wern't that loud and signal had a reason to do so. That was when they worked on the cryptocurrency and the spam protection.
In signals case it dosn't matter much if the server is compromised since the important part happens on the client side. The server can only forward encrypted salad or not deliver a message. Or log the meta data of the messages. E2e will always be there, despite the server being compromised.
I find Telegram to be at least as trustworthy as Signal. Signal has a lot of red/orange flags that bother me. For example, Telegram is not based in the United States, whereas Signal is.
An app designed by US company doesn't represent anything related to security.
The founder of telegram always complains that the FBI has access to signal, apple and other related chat apps.
He suggests to use private chat, if it is confidential. The message transactions happens between peer to peer and it doesn't go to the server. He was claiming all the privacy feature that you get from signal is the almost same as private chat. Signal stil uses the server.
The server’s trustworthiness does not matter for Signal. The app is designed to work securely regardless of the server. Moreover, even if the server software is open source, you cannot be sure that they run the same code that they publish.
My account was compromised once, though I have 2FA enabled. I assume that I was accessing my account from a browser on a windows pc, it had virus but not 100% sure. Someone was able to access it, change my name send multiple crypto related links to users in bulk.
It contained years of chat history with my wife. I was able to recover the account. But I deleted all the chat history.
I still use it to get alerts from various automated scripts I use, mostly for the bots with free API access. No personal data go in there.
The mistake might be from my side. But if someone takes over your account, you lose everything.
So, I have no way of actually verifying the validity of this, but, when I deployed (former US military) we were told that Russia and China had cracked telegram and WhatsApp and that signal was the only authorized encrypted messaging app.
E2EE is the most important protection for your messages. Otherwise, it means that all of your messages can be accessed just like a word file in their server. It’s up to you
I read long ago of criticisms about encryption algorithm by experts. Instead of using existing standards they baked their own algorithms. They were not recognised cryptograph experts.
Afaik, they improved it over time. But there might still be issues.
In sum, trust is not your friend and up to you without E2EE.
Would you rather lose a contact if they insist on a communication channel that's leaking metadata but the content is e2ee (WhatsApp for example)? (Or perhaps in your view keeping the content secure is more important than anything?)
Asking out of curiosity, I'm aware that every person has their own threat model
Yes, it does. You can try it. Respond to my comment (some people are getting annoyed) with the same bot name + a short time (like 5 minutes). You'll get a notification in your inbox.
What keeps me from using Telegram is the server side is closed source; they have been known to work with governments; and been willing to censor content. There are enough better options that I have zero use for them.
Thanks everyone on sharing your thoughts ln this! This has been really helpful!
I see some saying their policy says one thing about cooperation with law enforcement but they seem to have been doing just the opposite, reducing the trust overall in the rest of their promises (e.g. their data collection).
Some compared to the closer to ideal apps such as Signal or Matrix in terms of privacy.
I'm curious to also hear what do you do to compromise to keep your social connections?
The practical side of navigating the current state of the Internet and people's social life.
It's been an uphill battle with asking folks to use Signal, and Telegram seem to be better than giving out info to Meta.
