What is MAL-2026-16116?
MAL-2026-16116 is a malicious package in etoro-builders, published on 10 Sep 2026.
Official description
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/<hostname>/<username>/<cwd>. 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.
What should I do about MAL-2026-16116?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
