How I accidentally breached a nonexistent database and found every private key in a ‘state-of-the-art’ encrypted messenger called Converso

But wait – it gets much, much worse

As I was finishing up the above post, I noticed something a little strange in the code – something I’d glossed over earlier. There are a ton of references to what looks to be functions related to Google’s #Firestore database.

#Converso

Using the Seald credentials from the app's code, plus a random user's phone number and user ID from Converso's public database

is the databag protocol/design documented somewhere? does it claim to have forward secrecy?

from a quick glance I see here they’re generating an AES key from a passphrase and using it to encrypt an RSA private key, which is… not a good sign.

fwiw https://simplex.chat is another thing which seems to have similar goals and functionality but is better documented.
