It collects hostname, username, current working directory, platform, and the output of OS commands including `whoami /all`, `ipconfig /all` / `ifconfig`, `tasklist` / `ps aux`, directory listings of `/`, `C:\\`, and the user's home, and a dump of environment variables. The collected data is transmitted via HTTP GET and POST to the hardcoded bare IP endpoint `http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/v4/...`. The package's declared main is an empty stub and its description (\"Internal service client library\") combined with the implausibly high version number `99.0.2` is consistent with a dependency-confusion attack targeting an internal `etoro-aggregator` name. The manifest plus the preinstall script constitute the entire payload; installing the package leaks installer host identity, network configuration, filesystem structure, and environment variables (which routinely contain credentials and tokens) to an attacker-controlled endpoint.\n",
