Emphasizing "running the most recent versions of WhatsApp", does this mean the fancy new protocol can still be downgraded to the old one by an older client? I'd save the fanfare for a few more months yet
- folz 11y agoNope. From the article: "Once a client recognizes a contact as being fully e2e capable, it will not permit transmitting plaintext to that contact, even if that contact were to downgrade to a version of the software that is not fully e2e capable. This prevents the server or a network attacker from being able to perform a downgrade attack."
