A Telegram Channel is a feature within the Telegram messaging app that allows one or more administrators to broadcast messages to a large audience. Unlike group chats, only admins can post in channels, while subscribers can read the content but not respond directly. Channels can be public or private and are commonly used for sharing news, updates, or specialized information. In cybersecurity contexts, Telegram Channels are sometimes exploited by hacker groups to distribute announcements, leaks, or propaganda due to their ease of use and relative anonymity.
