It's possible for any message that is not marked as delivered.
All Facebook has to do is not mark messages as delivered, i.e. lieing to the device, which can probably be done easily. So they could ask a device to regenerate keys and send the same message again, over and over again.
- Jarwain 10y agoThis would just result in the same encrypted message being sent over and over, albeit encrypted with different keys each time, right? The only way the content of the message would be vulnerable is if one of the new keys are insecure/compromised, unless there's something I'm missing.
