In 2018, Russia banned Telegram although it reversed the prohibition two years later. Despite Telegram's origins, its approach to users' security has privacy advocates worried. Sebi said data, emails and other documents are being retrieved from the seized devices and detailed investigation is in progress. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. 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.
