I am liking how this time around a lot of people are outright calling the media out on their parroting Telegram's PR bullshit about how "encrypted, secure, private" the service is.

(it is not.)

As in, not just writing about how Telegram is neither of these things, but very clearly pointing a finger at the media and going: "stop spreading this misinformation, you are putting people in danger."

Keep this pressure on!

#Telegram #Media #InfoSec

Yesterday I shared my own write-up on Telegram's failings, today I came across Matthew Green's stellar blogpost:
https://blog.cryptographyengineering.com/2024/08/25/telegram-is-not-really-an-encrypted-messaging-app/

And this blogpost *starts* with calling the media out on this.

Fantastic.

At this point it's clear Telegram has no interest in fixing their stuff. We should not be talking to them, we should be talking about them to the media so that they stop promoting it.

Because as I said yesterday: that constitutes journalistic malpractice.

A Few Thoughts on Cryptographic Engineering

Great post, hits the nail right on the head. Thanks for sharing this @rysiek.

This kind of journalistic malpractice is usually caused by ignorance, in which case they need to be called in and patiently educated. But in some cases I think there is an intent to mislead, by people who ought to know better. They need to be contacted in private and given a chance to retract and apologise, and if they don't, they need to be publicly called out on their wilful malpractice.

"Indeed, it no longer feels amusing to see the Telegram organization urge people away from default-encrypted messengers, while refusing to implement essential features that would widely encrypt their own users’ messages. In fact, it’s starting to feel a bit malicious."

A Few Thoughts on Cryptographic Engineering

#Telegram always smelt like a honeypot to me;

* centralised, tick (like Signal)

* encryption doesn't work for groups, only 1:1, tick (like Signal)

* opt-in E2EE for 1:1 chats while heavily promoted as "encrypted messenger", tick (unlike Signal)

* Roll-Your-Own cryptography, tick (maybe like Signal, but crucially...)

* no source code published for server, so no independent auditing of cryptographic primitives or implementations, tick (unlike Signal)

I can't fathom why anyone uses it.

Can you elaborate on what you mean by the '(like Signal)'?

Private Group Messaging

One of the major features we introduced in the TextSecure v2 release was private group chat. We believe that group chat is an important feature for encrypted communications projects, so we wanted to try to summarize some of the existing work in this area, as well as how TextSecure’s group chat pr...

Signal Messenger
Thanks for the links @bengo. A lot of thought has been put into how private group chats on Signal might be encrypted, as those links indicate. But the last I heard they're still not encrypted by default in the Signal service. If my info is out-of-date, I'd appreciate a link where I can confirm that.

@strypey I think you might be confusing signal with telegram. telegram has some stuff that is not encrypted by default. signal is always encrypted and always has been, regardless of groups/1:1

@bengo
> Signal is always encrypted and always has been, regardless of groups/1:1

The closest thing I can see at the first link is;

"... messages and calls cannot be accessed by us or other third parties because they are always end-to-end encrypted."

Please quote me the text I missed specifying that *groups* are encrypted.

The second link is a claim by a *deleted* user on dReddit. I don't believe what I read on toilet walls, and neither do I take anything said or web forums as gospel truth.

@strypey I find this pretty funny. "A Signal group is built on top of the private group system technology." https://support.signal.org/hc/en-us/articles/360007319331-Group-chats
which links to https://signal.org/blog/signal-private-group-system/
which links to the IACR paper from 2019 I linked to a month ago..

"Signal groups are built on top of the new private group system technology we previewed last year, which gives you a modern group chat experience while keeping your groups private"

If this stuff doesn't convince you, nothing I say will

> If this stuff doesn't convince you, nothing I say will

What would convince me is a link to a page that contains both the words "groups" and "encrypted", not just one or the other. I'm confused as to why you think anyone ought to be convinced by anything less. Of the three links in your last post, one *one* does that;

https://signal.org/blog/signal-private-group-system/

Which just shows how inclined some people are to take positive claims about Signal on faith, while demanding robust sources for negative claims.

Technology Preview: Signal Private Group System

Groups are inherently social, and Signal is a social app. Whether you’re planning a surprise party, discussing last night’s book club meeting, exchanging photos with your family, or organizing something important, group messaging has always been a key feature of Signal.
