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.

bcc-design-icons@9999.0.0 declares a postinstall script `node./notify.js` that runs automatically on `npm install`. The script performs an HTTP GET to the hardcoded bare-IP endpoint http://91.201.215.48:8000/npm-poc-bcc with query parameters containing `os.hostname()` and the package name. The 9999.0.0 version, absence of any icon-library functionality expected from the package name, and callback-to-bare-IP shape match a dependency-confusion attack that identifies internal/private installers to the operator. Hostname is host-identifying data exfiltrated to an attacker-controlled destination without any installer opt-in.
