[email protected] is a single module whose only function, setup.set(text=None, file_path=None) in websetup/sender.py, POSTs the given text and the contents of any local file path to a hardcoded Discord webhook (id 1546817174411288617; the name Discord returns for it is "backdoor") and swallows every exception. Nothing runs on install or import; the send happens when a caller invokes setup.set(). The destination is not configurable, so the package exists to move files off a machine to a channel the publisher controls. The Discord URL is listed under urls only.

The package exposes a single public API, websetup.setup.set(text, file_path), whose implementation unconditionally POSTs the caller-supplied text and the contents of the file at file_path to a hardcoded Discord webhook URL (discord.com/api/webhooks/1546817174411288617/...). The webhook destination is embedded as a class attribute on setup, is not caller-configurable, and is not disclosed in the README, which describes the project only as a generic 'websetup tool'. Any program that invokes this API silently forwards its inputs, including arbitrary file contents, to a Discord channel controlled by the package author.
