TeleMessage came into the spotlight last week after it was reported that former U.S. National Security Adviser Mike Waltz was using TeleMessage’s modified version of Signal. Israel-based TeleMessage, owned by Smarsh, offers its clients a way to archive messages

I find this app so pointless, you can export your Signal chats yourself. They could have instead invested into Signal directly to ask for an archival piece where all parties agree that the chat will be exported to x folder, in x format, but once that exports done they will be wiped from Signal itself within a week. Some sort of chain of trust thing. Bonus points if you enforce validating keys between people before they can all be in a group chat.

Heck you could even require that exported chats have a password defined by the end-user, so its not just sitting there in plaintext. I wonder how much of this TeleMessage even tried to do, I have a feeling its a hacked up app that does what's advertised on the can, with no emphasis on securely doing so.

Would handling governmental data make you a high value target?
