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. So, uh, whenever I hear about Telegram, it’s always in relation to something bad. What gives? Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. However, the perpetrators of such frauds are now adopting new methods and technologies to defraud the investors. Oleksandra Matviichuk, a Kyiv-based lawyer and head of the Center for Civil Liberties, called Durov’s position "very weak," and urged concrete improvements.
