test-npm-snurkeburk-hackerone @1.999.0

Summary

The package's preinstall lifecycle hook runs node index.js, which shells out to collect installer host identifiers (hostname, cwd, whoami) and the installer's public IP (via curl to ifconfig.me), hex-encodes the concatenated result, and issues nslookup queries against subdomains of snurkeburk.com. This exfiltrates installer host identity over DNS at npm install time, before any consumer code runs. There is no legitimate purpose for a package to encode host identifiers into DNS lookups against an author-controlled zone.
