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 preinstall command suppresses all output by redirecting to `/dev/null 2\u003e\u00261`, hiding the beacon from the installer.

Installing this package causes silent leakage of installer username, working directory, and host metadata to a third-party endpoint.\n\nAny computer that has this package installed or running should be considered fully compromised.
