a-onesite@99.9.9 ships an empty index.js and no library functionality. Its package.json declares preinstall, preupdate, and test scripts that all invoke wget against http://eoy34oyrep9j5x8.m.pipedream.net with the installer's username ($(whoami)), current working directory ($(pwd)), and hostname ($(hostname)) as query parameters. The preinstall hook fires automatically on `npm install`, sending installer-identifying reconnaissance data over plaintext HTTP to a third-party collection endpoint unrelated to any advertised purpose. The version number (99.9.9) and empty code payload are consistent with a dependency-confusion reconnaissance beacon rather than a functional package.
