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.

On `npm install`, the declared postinstall hook runs `node index.js`, which reads `os.hostname()` and a timestamp, base64-encodes the JSON payload, and issues an HTTPS GET to `https://estimator-nemeses-unwatched.ngrok-free.dev/canary?d=<base64>`. The destination is a hardcoded ngrok tunnel unrelated to any registry or vendor infrastructure, and the beacon fires automatically without any caller action or opt-in. The package's own metadata describes it as a `Dependency Confusion to RCE` proof-of-concept, and the install-time callback carries the installer's internal hostname to an external third party.
