+# Persistent Reverse Shell - Telegram Based
+
+A script used to configure a persistent reverse shell on a Linux computer through a pre-configured Telegram Bot.
+
+**Category**: Execution
+
+## Dependencies
+
+* Internet Connection
+
+## Description
+
+A script used to configure a persistent reverse shell on a Linux computer through a pre-configured Telegram Bot.
+
+This payload is based on [Telegram Persistent Connection](Telegram_Persistent_Connection) payload for create the Telegram connection.
+
+The script accept the `/reverse` command using the format `/reverse <shell_command>` and split `/reverse` from `<shell_command>` through the `extract_command()` function, then execute the command acquired acquiring the output through the function `run_command()`.
+
+Because Telegram uses a limited size per message, the script divides the output of the command into a theoretically infinite chunk of 1000 characters in length that will be sent one by one through the Telegram Bot.
