etoro-aggregator@999.0.0 ships a preinstall.js that runs automatically on npm install and issues an HTTP GET to http://209.126.81.147/etoro-depconf-poce346552f776f/npm/<hostname>/<username>/<cwd>, encoding os.hostname(), os.userInfo().username, and process.cwd() as URL path segments. The version number (999.0.0), generic package name, and absence of any legitimate library code are consistent with a dependency-confusion lure: installing the package causes the installer's host identity to be sent to an attacker-controlled bare-IP endpoint over plaintext HTTP, providing reconnaissance for targeted follow-on attacks against organizations whose internal package names collide with this name.
