If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The tarball ships beacon scripts (`beacon18.js`, `beacon_linux.js`) that import `child_process`, `os`, and `http`, read host identifiers via `os.hostname()` / `os.platform()`, and issue outbound HTTP `GET`/`POST` requests carrying that data. The combination — automatic install-time execution, host enumeration, child_process reachability, and unsolicited outbound HTTP from an unknown low-reputation package named with a random suffix — matches a host-beacon / exfiltration shape with no legitimate library purpose. Installing this package on a developer or CI machine causes immediate disclosure of host metadata to an external endpoint and provides the publisher a foothold for follow-on commands.\n\nAny 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.
