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.

package.json declares a preinstall script that runs index.js on npm install. index.js collects host identifiers (os.homedir(), os.hostname(), os.userInfo().username, dns.getServers(), current working directory) along with the contents of the package.json and POSTs them over HTTPS to the hardcoded external host meta.brs.cx. This behavior fires automatically on install with no user interaction, and the collected data is characteristic of dependency-confusion / internal-name reconnaissance beacons used to identify targets for follow-on attacks.
