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 package occupies an npm name referenced by a vendor UI that instructs operators to invoke it via `npx`, so running the documented command causes host identity data to leave the operator's machine to a third-party OAST endpoint with no opt-in. The tarball metadata self-describes the release as a placeholder registered to demonstrate the dependency-confusion vector, but the shipped code performs a real installer-side data leak on execution, and the namespace remains available for future publishes by the same account with operator-level code execution on any host following the vendor's instruction.\n\nAny computer that has this package installed or running should be considered fully compromised.
