Telegram | DID YOU KNOW?
Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. It is unclear who runs the account, although Russia's official Ministry of Foreign Affairs Twitter account promoted the Telegram channel on Saturday and claimed it was operated by "a group of experts & journalists." In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies. 'Wild West' Messages are not fully encrypted by default. That means the company could, in theory, access the content of the messages, or be forced to hand over the data at the request of a government.
