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`, postinstall.js issues an HTTP GET to a hardcoded bare-IP endpoint at http://130.49.177.51:18080/p/dc-20260627-yandex-geobase carrying the package name, version, and a campaign tag (`bb-yandex-geobase-20260627`). The beacon fires automatically as a lifecycle script with no user opt-in, confirming code execution inside the installer's environment and exposing the installer's source IP / network position to an attacker-controlled host over plain HTTP. The package additionally declares a dependency on `yandex-geobase` and labels its callback with that package name, consistent with a dependency-confusion probe targeting the `yandex-geobase` namespace. Installer impact: any machine that resolves and installs `dc-repro` silently emits a network callback to the hardcoded IP at install time.
