Summary
Malicious code in requestor-util (npm)
Details

requestor-util@99.9.1 is a hollow wrapper (empty index.js, placeholder 99.9.1 version) whose only effect on install is to resolve a dependency declared as a direct tarball URL: "ltidisafe": "https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.4.6.tgz". npm install fetches whatever bytes currently live at that mutable Google Cloud Storage URL and executes any preinstall/install/postinstall lifecycle scripts contained in that tarball on the installer's machine. The URL is not on the npm registry (bypassing registry-side scanning) and is controlled by whoever owns the GCS bucket, who can swap the payload at any time without republishing the wrapper. The hollow-main + off-registry-tarball-dependency shape matches the dropper-lure pattern: the wrapper's function is to force resolution of an attacker-mutable external artifact into every installer's dependency tree.

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.
