Session | Send Messages, Not Metadata. | Private Messenger

Session is a private messenger that aims to remove any chance of metadata collection by routing all messages through an onion routing network.

^Session

Gebruik je #WhatsApp? Dan support je #Meta. #Instagram is ook van Meta.

"Het is dinsdag niet mogelijk om verschillende zoekopdrachten gerelateerd aan politieke tegenstanders van Donald Trump uit te voeren via Instagram."

Wil je werkelijk een bedrijf met zulke ondemocratische praktijken steunen?

Maak de switch je kunt het! Heb je vragen, laat het me weten!

There's a "Signal deanonymized" thing going around:
gist.github.com/hackermondev/4…

Stay calm. Deep breaths.

👉 while this is a real consideration, the only thing the attacker gets from this is a very rough (kilometers or tens of kilometers radius) location

👉 other communication platforms that use any kind of caching CDN to deliver attachments are just as affected

👉 you almost certainly should continue to use Signal, unless you specifically know that this is a big problem for you.

Personally, I don’t think the impact of the "which Cloudflare server is this Signal user closest to" attack is that bad. However, it highlights yet another quirky side effect of #Signal being built on cloud infrastructure.

Cloudflare Issue Can Leak Chat App Users' Broad Location

A security researcher made a tool that let them quickly check which of Cloudflare's data centers had cached an image, which allowed them to figure out what city a Discord, Signal, or Twitter/X user might be in.

By popular demand, a single post to boost global switch day across multiple platforms on February 1st 2025.


For those who can no longer get behind Musk or Meta's new policies and feel like switching (e.g. from #Whatsapp to #Signal, from #Instagram to #Pixelfed or from #X to #Mastodon) I made you some graphics to use freely in communicating with your contacts.

Let’s lead by example 🙂

🚨 Privacy Win 🚨

The USA's loudest endorsement ever: CISA urges everyone to use encryption!

Use services like #Signal and #Tuta to secure your online communication.

Here's the news: tuta.com/blog/us-cisa-endorses…

Die Welt ist voller Messenger und gefühlt nutzen die allermeisten #WhatsApp, #Telegram oder #Signal.

Alle haben ihre individuellen Vor- und Nachteile und wer sich dann noch die die üblichen Sicherheitsseiten anschaut, z.B. @kuketzblog , wird schnell feststellen: Es gibt nicht DEN einen Messenger, den alle gut finden.

Warum ich unter den verfügbaren Alternativen neben @signalapp @matrix nutze, habe ich hier zusammengefasst:

bsdbox.de/matrix

V posledních dnech převádím komunikaci s nejbližší rodinou na #Signal. ➡️ Ale donutit k přechodu větší počet lidí je problém, nikdo moc nechce další IM aplikaci a raději zůstane tam, kde většina. 😞

Bohužel v dnešní době, kdy o nás státy, nadnárodní korporace a další subjekty sbírají všemožná data, se začíná soukromí zcela vytrácet. ⚠️ Smutné je, že většině lidí je ztráta soukromí v této podobě úplně ukradená. 🤯

Signal jsem zvolil, hlavně díky jednoduchosti a nativnímu E2E šifrování. Účet si tam zvládne vytvořit a nastavit opravdu každý. signal.org/install

Signal Messenger: Speak Freely

Say "hello" to a different messaging experience. An unexpected focus on privacy, combined with all of the features you expect.

^{Signal Messenger}

I installed #Signal and #Conversations_im on a clean install of #GrapheneOS on my Pixel 4a and measured the battery impact. The results are shocking!

Both messengers had only one contact: my regular phone.

I used my regular phone to send messages to the Pixel 4a (which was not used for anything else over the course of the experiment).

I always sent the same message via Signal and #XMPP (mixing up which app went first). In total I sent ~32 messages in intervals of 10mins to a few hours.

Signal messenger is hosted on Amazon, Google and Microsoft servers

I’ve been on Fedi for a year now and have fallen in love with the platform, so here’s my introduction! I studied computer science with a focus on RTOS and FP/PL, but I’m about to start my final semester of law school. I’ll be practicing at a boutique firm that primarily handles IP cases once I’m barred. I foilboard and I play way too many rhythm games in and out of the arcade.

I contribute to open source projects where I can, and I write up my experience in my digital garden which I’ve been maintaining for over a year now. It’s also a good place to find usage tips for projects/tools that you might want to use.

My passion for tech also includes privacy, and I’m an advocate for minimizing your digital footprint. GenAI is a scam and its purveyors are causing real harm while they sell it as hard as they can.

So... #Signal and #Wire, which both have issues, but not #Matrix / #XMPP? And for video, 2 #YouTube front ends and a proprietary YouTube clone, but no direct mention of #Peertube? And for Translation, the proprietary #Deepl, but no mention of the local and #Privacy respecting #Firefox #translate

I appreciate the intent of this post, but the research is... outdated at best.

Signal is working on the ability to set nicknames and add notes to contacts! Notes and nicknames will only be visible to you and will be end-to-end encrypted.

This feature is currently available in Signal for Android v7.2, but it will likely come to other platforms soon. Please note that this feature is currently under active development, so its design and functionality are subject to change.

Ayé enfin le nom d'utilisateur.
Souvenez vous qu'il est fait pour être éphémère si vous le souhaitez. Vous pouvez en changer n'importe quand.
(Oui le numéro à la fin est obligatoire, mais vous pouvez le changer)

C'est cool de pouvoir choisir plusieurs manières pour les gens de vous contacter: nom d'utilisateur, URL ou QR code.

Et le réglage de la confidentialité du numéro de téléphone (séparé) est bien :

They have spent countless hours and some chunk of money to add features that the common user doesn't even use (e.g stories which since it's launch, even Signal themselves does not use it to update users of development 🤦)

Many of my contacts already left #Signal ! 🤕😮‍💨

Yes I have recurring donation to them. Yes, I'm trying to keep calm, but damn it, this is ridiculous that Signal is still this much behind the market. Stability, quality, features, design, using phone number,... . Come on!

Exposing my DID and then farming my contact database so it can tell me when people I know sign up for #Signal (and Vice Verse - it tells people who have your DID in their contact database when you're a signal user too) is an egregious invasion of my privacy!!!

I do understand that Signal has been working to get rid of the #DID requirement, and received notification of such a day or so ago, but there's still a bad taste left in my mouth for encroachments.

The next beta version of #Signal will be version 7.0.0.
There's a good reason for the round number. This will be the first version where usernames and phone number privacy are available outside of the staging environment.
From this version on, you'll be able to talk to people on Signal without revealing your phone number, and also, you may use Signal without revealing to people who have your number saved that you do.
This is huge.

Telegram leaks your IP address to anyone in your contacts during a call. And a researcher has created a tool to easily exploit this.

#Telegram says this is expected behavior, so there's nothing to fix or change.

That's why our top WhatsApp alternatives are #Signal and #Threema: tuta.com/blog/best-whatsapp-al…

Jestli něco ničí moji pozornost, je to neustálé odpovídání na různých chatovacích aplikacích.

I když se to snažím stáhnout na minimum, tak mám 4 - Signal, Whatsapp, iMessage, Twitter a Linkedin zprávy.

Před rokem jsem objevila #Beeper a dneska konečně dostala přístup.

Pořád mě ale nejde do hlavy, jak je na tom s bezpečností, například u kryptovaných messengerů jako je #Signal.

Pokud by to fungovalo, je to topovka.

Today, two open letters from academics on the scientific arguments against the current #CSS (client side scanning) initiatives have been released:

* The first (in English, internationally coordinated) one is online at tinyurl.com/CSAScientistsLette… and still open for additional signatures.

* The second (in German, by #Austrian academics) one is online at ins.jku.at/chatcontrol/ and explicitly includes law experts in addition to the arguments from a security, privacy, and AI perspective.

This debate is expected to gain new steam with #Spain taking over the EU council presidency, given recently leaked statements like "Ideally, in our view, it would be desirable to legislatively prevent EU-based service providers from implementing end-to-end encryption" (wired.co.uk/article/europe-bre…).

Please boost on any channels you deem adequate. The discussion is still open, and we have little time to bring it to a more rational level.
