If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On npm install, preinstall.js runs automatically and sends the installer's hostname, username, platform, and current working directory via HTTP GET to http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/npm/v2/<host>/<user>/<platform>/<cwd>, then executes `whoami; id; hostname -f` (or `whoami /all` on Windows) via child_process and POSTs the command output to the same hardcoded bare-IP endpoint over plain HTTP. The package.json advertises the package as an `Internal service client library` at version 99.0.0 with no real functional code beyond the preinstall hook, and the beacon path segment `etoro-nuget-verify...` targets an internal eToro namespace, matching the dependency-confusion recon pattern.
