If it's not how it stores or encrypts attachments, it means it has to do with the way apple handles them while they aren't encrypted, right? Is there any other attack vector if we're assuming the encryption itself is secure?

- Christina Garman,@matthew_d_green, Gabriel Kaptchuk, Michael Rushanan, and I found some crypto exploits in iMessage

- And now you have 14 hours to guess what the attack is. As a hint, no, its not a bug in how Apple stores or encrypts attachments.
