Package name suggests build telemetry tooling, but the tarball ships beacon scripts (beacon18.js, beacon_linux.js) wired to a postinstall lifecycle hook ("postinstall": "node run.js" in package.json line 9). On install, these scripts collect host identifiers via os.hostname()/os.platform() and child_process, then issue outbound HTTP GET/POST requests via http.request from the installer's machine. This combination — auto-execute on install, host fingerprinting, and outbound HTTP exfiltration — is a classic install-time host beacon / data-exfiltration pattern. There is no legitimate build-tracking reason to fingerprint the host and beacon out at install time without consent or configuration.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
