3.5 Billion Accounts: Complete WhatsApp Directory Retrieved and Evaluated
Vienna researchers retrieved all WhatsApp numbers. The 3.5 billion profiles represent the largest data leak in history—and it's worse than you might think.Daniel AJ Sokolov (heise online)
A surprising amount can be read from the data, and for some users, it can be life-threatening.
The entire WhatsApp profile database (including correlatable phone numbers and face photos) leaked.

No, there was no leaked database of 3.5B #WhatsApp users. Researchers from Vienna simply used the contact discovery method with all possible phone numbers to get contact data of 3.5B users. They informed WhatsApp who kinda fixed it by setting rate limits for contact discovery and the researchers deleted their collected data. Read the paper instead of clickbait :)

Wow, Vienna scientists received the complete WhatsApp member directory, containing 3.5 billion user entries. Yes, it’s just the directory, no messages, but the whole directory was available online - totally unprotected.
Any more reasons for not using WhatsApp required

Hey, did you know that Movim allows you to link your #Discord, #Telegram, #WhatsApp and #Matrix accounts to your main XMPP one and chat with all your contacts in one integrated platform? 🤩
We are working hard with @nicoco to ensure a perfect integration with the Slidge gateways project slidge.im/ 🥸🤝🥸
Message synchronization, reactions, stickers, GIFs, chatrooms, invitations, file transfer... you can now find all those exciting features fully working across all your linked accounts in Movim ✨.
Now you can move to #XMPP while staying in contact with all your friends. 👌
Try it out on mov.im/ or by deploying your own instance 😸!
@TheDailyBurble, happy to help.
Another cool feature of #XMPP are "gateways" that make it relatively easy to connect with other IMs.
e.g.
#Libervia to #ActivityPub and #email (CC @Goffi )
nlnet.nl/project/Libervia
libervia.org
#Slidge to all sorts of other IM like #Matrix, #Mattermost, #Steam, #Discord, #Whatsapp, FB … (CC @nicoco )

Slidge is a chat gateway library for XMPP built in Python, and a set of gateways for other networks.slidge.im
🇷🇺 Russia wants China's Great Firewall
After Tuta Mail, it's now also blocking #Signal & #WhatsApp to stop its citizens from using #encryption
Together with @torproject, @fightforfuture and others we are standing up to say: Stop! ✊
Everyone deserves #privacy.

I give a fiver each month to the wonderful FOSS-type things below:
- Signal (killing Meta's WhatsApp)
- Libre Office (slaying Microsoft's 365)
- GrapheneOS (kicking Google Stock Android in the goolies)
If you use any of these - and you can afford to - why not set up a monthly dontation to the wonderful organisations above.

Everyone is now realizing that WhatsApp is evolving towards its latest form (archive.md/L3W74). If you value secure messaging, you may want to check out @signalapp or @matrix (wich is #federated). EPFL also has its own Matrix instance at matrix.epfl.ch (use @element as a client).

Im very impressed with Slidge whatsapp bridge on my Prosody server. It is far more stable and reliable than I ever expected, and means I do not need any Facebook owned apps on my personal phone, as whatsapp is installed on my work phone only and slidge is linked to that ( my workplace use it, because free and “everyone has it” heh.)
My family have refused to move over to xmpp after the matrix server we used shut down, even after I ran a few different test servers on both prosody and ejabberd and tested reliability of the platforms and mobile notifications. (Both work great, but at the time I decided on Prosody.) My family’s reasoning was that they already use whatsapp and I’m just being weird.
The slow creep of rights and privacy erosion is disturbing to me, and the small amount I can do like running my own fedi instance and chat server at least helps me keep my sense of sanity in this crazier and crazier world of surveillance and data harvesting.
A bridge to the chat platform at least means it isn’t on my phone that is with me everywhere, and doesn’t inconvenience my family from me being the “weird extremist”.
We do what we can.

How to turn off WhatsApp ads – once and for all. | Tuta
WhatsApp users say hello to ads - or turn them off with this guide! Meta-owned instant chat app has announced that it will soon start showing ads. But why did WhatsApp break its no-ad promise?Tuta
Aunque el objetivo del vídeo es dejar a #WhatsApp en evidencia, también otorgo una parte no-despreciable del vídeo a #Signal, como la gran alternativa.
También nombro a #XMPP (vivo amenazado por la furia de @kyva), PERO:
Signal es el único "quita-y-pon" 🧩 que tenemos ahora mismo, para seguir conversando con **nuestros contactos telefónicos**, sin tener que ir preguntando a todo quisqui por su dirección.
Que ya los iremos metiendo en el saco federado, pero tú estate en Signal mientrastanto. 😉
Hice un vídeo para que puedas enviárselo a tus personas cercanas, explicando lo fácil que es dejar #WhatsApp, y por qué es importante hacerlo. 💬

Is #WhatsApp introducing #ads the last straw for you?
noyb.eu/en/whatsapp-getting-ad…
Consider using #Prav instead, which is:
🗳️ community-driven, so you can push for features you like, and, more importantly, vote against changes you dislike!
🆓 freedom-respecting, so you can fork the code to make things work the way you want
standards-based, using the #XMPP protocol
🌐 part of the federated #Jabber network, so you can switch apps and instances without having to drag everyone else along with you!

#deltachat is secure against server-side group membership changes but for a very different reason than #signal which keeps encrypted group membership data in a central store.
Delta Chat has _no_ central store but implements a rigidly tested #p2p group membership model where servers play no role github.com/chatmail/models/tre…
Both signal and delta chat are safe against recently published attacks against #whatsapp that can add members to chats, breaking end to end encryption. arstechnica.com/security/2025/…
WhatsApp provides no cryptographic management for group messages

My grandmother recently got locked out of #WhatsApp because her phone broke, and the spare one we had on hand is one WhatsApp has decided is too old to run on 💀
Fortunately, #XMPP has no such qualms! She's currently keeping up with the family group chat on #Quicksy while others of us use #Conversations, #DinoIM, and #Gajim. (Of course, extended family and friends are another matter 😔)
This serves as a reminder that closed apps may close you out—but open protocols have your back forever! 
that is why I don't like people recommending moving from #WhatsApp to #Signal, better use messengers that don't depend on US servers and companies, like European messengers like #ArcaneChat
I really recommend you to give a try to #DeltaChat anonymous login without any phone number or any private data required, you can create as many accounts and add as many devices as you want, all work smoothly no encryption problems with multi-device etc and it has a better interface than #matrix on the level of #WhatsApp and #Telegram super user-friendly and painless to onboard family and friends
And you LITERALLY own your data and can browse it and search it offline
#WhatsApp shares its metadata with #Meta
They know:
✅ Your location
✅ Your device
✅ Who you're writing
✅ When you write them
✅ How often you write them
✅ Whether they reply
