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 :)

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.

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

This has been another colossal fuck up by Meta, again. And another leak that goes unpunished, again.
Downloading Delta chat or Signal is not enough. Think beyond the headline.
Regardless of where you are, you need to hold these people accountable.

De esto no he escuchado nada por la tele https://www.heise.de/en/news/3-5-Billion-Accounts-Complete-WhatsApp-Directory-Retrieved-and-Evaluated-11083244.html
Y después quieren los políticos acabar con la privacidad en los chats y demás ¿Para que ? ¿Para que les sea aún más fácil a los actores malignos acceder aún más fácil a nuestro datos?

"Vienna researchers retrieved all #WhatsApp numbers. The 3.5 billion profiles represent the largest data leak in history"
"...downloaded all 77 million profile pictures visible to everyone—a proud 3.8 terabytes in total. In a random sample of half a million images drawn from this, a facial recognition routine found a human face in two-thirds of cases."
