Malicious code in metavu (npm)

package.json declares preinstall: node index.js, which fires automatically on npm install. index.js collects hostname, platform, architecture, home directory, username/uid/gid/shell, OS details, the output of whoami and id, and the current working directory, then POSTs the JSON payload to a hardcoded collector URL https://webhook.site/4f54203c-996c-4f52-b136-ef9b1fd0f64d/detox56 (index.js:7, index.js:108). The package has no functional code — empty author, empty description, and a bizarre version string 99.21.1-1.21.199 consistent with a throwaway dependency-confusion / recon probe. Installing this package leaks installer identity and host fingerprint to an attacker-controlled collector, enabling targeted follow-on attacks against the developer or build environment.
