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 declares scripts.preinstall = 'node vishu.js', which runs automatically on npm install. vishu.js resolves the installer's public IP via api.ipify.org, reads CI-related environment variables (CI, GITHUB_ACTIONS, GITHUB_WORKFLOW, GITHUB_RUN_ID and related), and issues an HTTPS GET to a hardcoded webhook.site collector URL carrying those fields. It additionally performs a DNS lookup of a subdomain constructed from os.hostname() under a hardcoded oastify.com (Burp Collaborator) domain, exfiltrating the installer's hostname via DNS. The package name typosquats the scoped @intlify/message-compiler package and its only functional code is this beacon.
