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. Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts.
