"Someone posing as a Ukrainian citizen just joins the chat and starts spreading misinformation, or gathers data, like the location of shelters," Tsekhanovska said, noting how false messages have urged Ukrainians to turn off their phones at a specific time of night, citing cybersafety. False news often spreads via public groups, or chats, with potentially fatal effects. Two days after Russia invaded Ukraine, an account on the Telegram messaging platform posing as President Volodymyr Zelenskiy urged his armed forces to surrender. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Despite Telegram's origins, its approach to users' security has privacy advocates worried.
