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.

This executes attacker-controlled JavaScript on any machine that runs `npm install` for this package, with no pinning, integrity check, or scoping. The destination is an ephemeral, mutable, attacker-operated tunnel — not a registry, not a publisher domain. Package metadata impersonates well-known maintainers of the express and mocha projects (author field set to 'TJ Holowaychuk'), and the stated description ('Integrate redis with cookies') does not match the shipped behavior, indicating deliberate impersonation rather than misconfiguration.\n\nAny computer that has this package installed or running should be considered fully compromised.
