But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. "Russians are really disconnected from the reality of what happening to their country," Andrey said. "So Telegram has become essential for understanding what's going on to the Russian-speaking world." 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. Despite Telegram's origins, its approach to users' security has privacy advocates worried. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts.
