Join David Greene, EFF Senior Staff Attorney and Civil Liberties Director, as he joins Lisa Rein to discuss the latest about Pavel Durov's arrest in France and the implications of Telegram's unencrypted group chats for its users.

Even Telegram's one-to-one direct messages are only encrypted if the "secret chat" feature is enabled by both parties.

Another troubling issue is that Telegram stores its messages in the cloud, as plain text, as this Tweet from Signal Founder Moxie Marlinspike explains: https://x.com/moxie/status/1828464949703909574

For these reasons, Telegram can't actually be considered a "secure messaging app" because real secure messaging apps, such as Signal and What's App, are end-to-end encrypted by default.

A lot of Telegram users might not care if their group chats aren't encrypted, as they are using group chats to broadcast to the public anyway, but for those who might be using Telegram for more sensitive group conversations, it's an important fact to make note of.
