The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Multiple pro-Kremlin media figures circulated the post's false claims, including prominent Russian journalist Vladimir Soloviev and the state-controlled Russian outlet RT, according to the DFR Lab's report. Despite Telegram's origins, its approach to users' security has privacy advocates worried.
