Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. False news often spreads via public groups, or chats, with potentially fatal effects. So, uh, whenever I hear about Telegram, it’s always in relation to something bad. What gives? "This time we received the coordinates of enemy vehicles marked 'V' in Kyiv region," it added.
