Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels. In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats you’re having with folks are not as secure as you may believe.
