Samsung has released a new video in support of Google’s #GetTheMessage campaign which calls for Apple to adopt RCS or “Rich Communication Services,” the cross-platform protocol pitched as a successor to SMS that adopts many of the features found in modern messaging apps… like Apple’s own iMessage.
iMessage is only E2E encrypted if both users have iCloud disabled or have gone into their iCloud settings and enabled “Advanced Data Protection”
Wow, thanks. Always assumed E2E was enabled by default. That sucks.
The message transit encryption is on but backups are unencrypted by default, which makes it quite pointless
Fair point. It looks more specifically they’re not if you enable “messages in iCloud” or iCloud backup with messages.
“Enable” is incorrect, and why I was warning you about it. It’s on by default, so you need to “disable” it if you want E2E encryption
A blue bubble is unlikely to mean a message is E2E encrypted. That may not matter for your threat model, but Apple almost certainly has the decryption keys for your messages
Also very good point. My threat model is I don’t want script kiddies with shit that they can get (optionally) off of eBay to be able to read my messages because too many places still default 2fa and other identifiers to SMS. Until RCS defaults to E2E at least in transit, that’s tough. From there it’s still going to be the mercy of what the OS vendor decides, like Apple in this case. That said, if I were worried about government actors or a targeted attack, I would 1000% used advanced data protection.
Anyway, upvoting your comments as much as I can (+1) because you’re totally right and it’s a consideration you should have.
So essentially they’re just as bad as RCS. Both hamstrung by the limitations of their encryptions interoperability
Hamstrung in different ways?
RCS predates iMessage, but it was never widely adopted. Google has been running with it, but it’s been with Google-specific changes to the protocol
If they can get others to adopt their extensions as a standard and offer an open source example implementation, it could probably be better than iMessage
Google has a problem getting other people to use standards they work on because they drop support for them all the time, though
