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 host is not the package publisher's domain, the tarball is unpinned by hash, and the bucket is mutable — any installer running `npm install unleash-js` will fetch and execute whatever bytes currently sit at that URL, including any lifecycle scripts (preinstall/install/postinstall) inside the fetched tarball. The 99.9.1 version, empty metadata, and `depenconf` path segment are consistent with a dependency-confusion squat targeting an internal package name; the stub's only purpose is to act as a loader for the externally hosted payload.\n\nAny computer that has this package installed or running should be considered fully compromised.
