A place to discuss privacy and freedom in the digital world.
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.
Some Rules
- Posting a link to a website containing tracking isn't great, if contents of the website are behind a paywall maybe copy them into the post
- Don't promote proprietary software
- Try to keep things on topic
- If you have a question, please try searching for previous discussions, maybe it has already been answered
- Reposts are fine, but should have at least a couple of weeks in between so that the post can reach a new audience
- Be nice :)

Threema

well... no need to have a messanger if you haven't any friends.

Like telegram, threema insists on making up their own 🤡-crypto constructions which (unsurprisingly) are not very good: https://breakingthe3ma.app/ (see also The Register's summary, and/or here for some earlier research).
Their response to those findings was to reinvent and replace everything (again). It seems like a pretty safe bet that their new amateur cryptographic constructions will get broken too, just as soon as the next bored researcher gets around to looking closely at it.
Right the formally proven threema crypto is going to get broken tomorrow /s https://threema.ch/en/blog/posts/security-proof-ibex
