Summary
Malicious code in etoro-builders (npm)
Details

Source: amazon-inspector (c9210fb131a2f661ae1d656fa461d45c6c54377179aecba06e6a07b4f357a00b)

The package's preinstall lifecycle script (preinstall.js) reads the installer's OS hostname, username, and current working directory via os.hostname(), os.userInfo().username, and process.cwd(), encodes them into a URL path, and issues an HTTP GET to a hardcoded bare-IP endpoint at http://209.126.81.147/etoro-depconf-.../npm///. The package name 'etoro-builders' combined with the implausibly high version 999.0.0 and minimal placeholder contents is consistent with a dependency-confusion payload designed to win resolution against a private internal package and beacon successful installs to the operator. Installer host identifiers leave the machine at npm install time to a third-party bare-IP host over cleartext HTTP.
