If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

in-install@99.9.1 declares its `ltidisafe` dependency as an HTTPS tarball URL hosted on a Google Cloud Storage bucket (`https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.6.9.tgz`) rather than a registry-resolved package. Running `npm install in-install` fetches that tarball and installs it into the installer's node_modules, executing whatever install/import-time code it ships. The bucket path is mutable by whoever controls it, is not subject to npm registry review, and is not pinned to a registry-audited artifact, so the bytes delivered at install time can be changed at any moment without a version bump. The package's own index.js is an empty export; the sole observable effect of installing it is pulling arbitrary off-registry code into the installer's environment.

Any 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. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
