Russian President Vladimir Putin launched Russia's invasion of Ukraine in the early-morning hours of February 24, targeting several key cities with military strikes. False news often spreads via public groups, or chats, with potentially fatal effects. Ukrainian President Volodymyr Zelensky said in a video message on Tuesday that Ukrainian forces "destroy the invaders wherever we can." But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content.
