If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The package's preinstall script (scripts.preinstall = 'node index.js') runs automatically on npm install and collects os.userInfo().username and os.hostname(), then issues a dns.lookup against a subdomain of 31ee29fe-db68-4fd3-86a2-2b707b9e95f0.dnshook.site with the username and hostname embedded in the queried label. This is a DNS-based exfiltration beacon: installing the package transmits installer host identifiers to a non-first-party canary domain over DNS resolution at install time. The version number 99.99.99 and package name shape are consistent with a dependency-confusion lure targeting an internal package name.
