Q: Can I make calls or video calls via Telegram?

We specialize in sending messages, large media and files — and we do this better than anyone out there. There are still many things that we can revolutionize in messaging. And messaging is obviously trending at the moment, so our focus remains in that area for now.

By simulating an attack originating from a mobile app/client-side vulnerability that gains additional permissions by running a kernel or root exploit, Zimperium was able to uncover Secret Chats that were readable in plain-text in the process memory, as well as in a Cache4.db file.
Additionally, once a chat was deleted, the user may think that it cannot be retrieved by anyone who is trying to read the Secret Chat’s content; however, an attacker can still obtain the content of the messages.
