Ukrainian forces successfully attacked Russian vehicles in the capital city of Kyiv thanks to a public tip made through the encrypted messaging app Telegram, Ukraine's top law-enforcement agency said on Tuesday. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. "The result is on this photo: fiery 'greetings' to the invaders," the Security Service of Ukraine wrote alongside a photo showing several military vehicles among plumes of black smoke. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels.
