Summary

The package's package.json declares a preinstall script that runs index.js automatically on npm install . index.js shells out via child_process.exec to collect the installer's hostname, current working directory, username, a package marker, and the machine's public IP (fetched via curl to ifconfig.me). The aggregated output is hex-encoded with xxd and split into DNS labels queried via nslookup against subdomains of snurkeburk.com, a DNS-tunnel exfiltration channel that bypasses egress HTTP filtering. Installing this package causes host identifiers and public IP to leave the machine to an attacker-controlled DNS namespace.
