Telegram Adds 'Delete Everywhere' Nuclear Option -- Killing Chat History (techcrunch.com)
Instant messaging service Telegram has added a feature that lets a user delete messages in one-to-one and/or group private chats, after the fact, and not only from their own inbox. From a report: The new 'nuclear option' delete feature allows a user to selectively delete their own messages and/or messages sent by any/all others in the chat. They don't even have to have composed the original message or begun the thread to do so. They can just decide it's time. Let that sink in. All it now takes is a few taps to wipe all trace of a historical communication -- from both your own inbox and the inbox(es) of whoever else you were chatting with (assuming they're running the latest version of Telegram's app).
This is probably quite effective. Consider that the worst most people have to worry about is normal law enforcement, who don't have supercomputers and zero day exploits available, so the best they can do is try to unlock your phone and check its contents.
Securely deleting data, especially if it is by deleting an encryption key for that data, is generally very effective against law enforcement and we have seen over and over again that it works.
