TM Signal (lemmy.world)

The scariest part of this recent news is that TM Signal seem(ed) to be interoperable. People using TM Signal could interact with actual Signal users. How are you to know whether or not your groups have people using bastardized versions of Signal? Are things like Session interoperable with Signal?

In no way does Signal prevent conversations from being archived. For all you know, a recipient could be screenshotting all of your messages, and they could even be using the official app when doing so.

If you don't trust your contacts, probably shouldn't be messaging them anything sensitive.

Yes of course. Signal can archive messages and they can be restored, you can screenshot messages and you can have them backed up as part of a policy like icloud backups.

My question is more about how do you know you're interacting with an authentic signal client, and not a bastardized one.

At the moment you can't. The only realistic way I could see that happening is if the servers would check the app's digital signature and refuse the app from communicating with the official infrastructure if it didn't match.
