During import, the package silently downloads and executes remote code. This code starts a web server in the separate process and listens for commands to execute from a C2 server, as well as periodically sends a beacon to C2 allowing discovery and finishing execution.

This package is closely related to Github repository https://github.com/xcummins/tg-outline-seller/ from the same author, where it's used as dependency effectively compromising its users.
