A comprehensive analysis of the cryptographic protocols used in the Swiss encrypted messaging application Threema has revealed a number of loopholes that could be exploited to break authentication protections and even recover users’ private keys.

    I wonder why they stick to their own crypto protocol instead of the state-of-the-art Signal protocol.

      I don’t know if the encryption protocol used for Signal represents the state-of-the-art. Probably, there are other valid encryption protocols; I refer, for example, to that one on which is based Matrix.

        Matrix uses the Double Ratchet Algorithm (“Signal protocol”) too, so do WhatsApp and Conversations ;)
