@Proton_Pass @Keroppo @CorvusCorax_01 @Sarthak4Alpha “the e2ee messenger that a load of people I know are already using”? 🤔 For most people, you’re describing WhatsApp. There’s a lot more to privacy (and even security) than E2EE.
English
@Keroppo @CorvusCorax_01 @Sarthak4Alpha Userbase differences, mainly. Much easier to be using the e2ee messenger that a load of people I know are already using over getting them all to use another.
Network effects are very important, especially when dealing with people who may default to non-private options.

How about: Do not use Telegram, period. Despite its image, it’s not secure by any modern standard.
Lukasz Olejnik@lukOlejnik
DO NOT use Telegram in sensitive applications. Telegram does not need to have its message encryption broken for users to be tracked at the network layer. Telegram sends MTProto over unencrypted TCP, exposing auth_key_id - a long-lived identifier tied to the client’s authorisation key. An ISP, hotel WiFi operator, mobile carrier, transit provider, or surveillance system on the network path can see that identifier if they can observe the traffic. It can remain stable across app restarts, IP changes, VPN use, network switches, and location changes. Secret Chats protect message content, but this leak is below that layer. That makes the attack passive. The risk is in retroactive correlation. Think a journalist using Telegram from different networks for months, then joining hotel or corporate WiFi under a real name. That one identity anchor could make old logs searchable for the same auth_key_id. The fix is simple - mandatory transport encryption for all MTProto connections, with no unencrypted fallback. Telegram chose not to do this. Source: @kaepora symbolic.software/pdf/gnmx-01.pdf

Today is #DeleteWhatsAppDay 🚮
Five years after WhatsApp’s controversial privacy policy change, Meta is expected to become the world’s largest digital ad company, making it more important than ever to question data-driven business models: threema.com/bp/deletewhats…

Many apps encrypt your data to protect it. 🔒
The key is to protect the key to decrypt it. 🔑

Some speak of a “hack,” others blame the victims. Both miss the point: the recent cyberattack on German politicians shows that there’s more to security than encryption. threema.com/bp/theres-more…

@Martiprime @romantikkiez Es lässt sich kein Zusammenhang herstellen zwischen einer Threema-ID und den Zahlungsdaten, die zum Kauf der App verwendet wurden: threema.com/de/blog/nachte… ^pr
Deutsch
@romantikkiez @ThreemaApp Daran war soweit ich mich erinnere nicht Threema schuld, sondern weil die Zahlung mit Kreditkarte erfolgte und man ihm daher auf die Schliche kam.
Deutsch
@romantikkiez @Martiprime Das ist nicht zutreffend. Wir geben nur auf behördliche Anordnung Daten heraus, und ausländische Behörden müssen in jedem Fall ein ordentliches Rechtshilfeersuchen gemäss Bundesgesetz über internationale Rechtshilfe in Strafsachen stellen: threema.com/de/transparenc… ^pr
Deutsch
@Martiprime @ThreemaApp Mag im konkreten Fall sein, aber grundsätzlich geben Schweizer IT-Anbieter immer Nutzerdaten - soweit sie Zugriff darauf haben - an ausländische Behörden weiter.
Auch ohne Rechtshilfersuchen.
Bei Proton lässt sich das sogar beweisen.
