Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. During the operations, Sebi officials seized various records and documents, including 34 mobile phones, six laptops, four desktops, four tablets, two hard drive disks and one pen drive from the custody of these persons. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels. In 2018, Russia banned Telegram although it reversed the prohibition two years later.
