At its heart, Telegram is little more than a messaging app like WhatsApp or Signal. But it also offers open channels that enable a single user, or a group of users, to communicate with large numbers in a method similar to a Twitter account. This has proven to be both a blessing and a curse for Telegram and its users, since these channels can be used for both good and ill. Right now, as Wired reports, the app is a key way for Ukrainians to receive updates from the government during the invasion. 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. Sebi said data, emails and other documents are being retrieved from the seized devices and detailed investigation is in progress. Despite Telegram's origins, its approach to users' security has privacy advocates worried.
