The Security Service of Ukraine said in a tweet that it was able to effectively target Russian convoys near Kyiv because of messages sent to an official Telegram bot account called "STOP Russian War." Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. Despite Telegram's origins, its approach to users' security has privacy advocates worried. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. Pavel Durov, Telegram's CEO, is known as "the Russian Mark Zuckerberg," for co-founding VKontakte, which is Russian for "in touch," a Facebook imitator that became the country's most popular social networking site.
