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.

Its package.json declares its sole runtime dependency as a direct HTTPS tarball URL — `\"ltidisafe\": \"https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.7.5.tgz\"` — bypassing the npm registry entirely. The path segment literally contains `depenconf` (dependency confusion). On `npm install`, npm fetches that tarball from an anonymous Google Cloud Storage bucket and executes any lifecycle scripts (preinstall/install/postinstall) it declares. The bucket contents are not vetted by the registry, are mutable server-side after publication, and the bucket owner has no apparent affiliation with the host package. The host package's only effect on installers is to drag arbitrary, swappable, attacker-controlled code into the install tree.\n\nAny computer that has this package installed or running should be considered fully compromised.
