ryan-pdf-js

ryan-pdf-js@99.9.1 is an empty stub package (index.js exports {}) whose sole purpose is to deliver an off-registry payload at install time. Its package.json declares its only dependency, `ltidisafe`, as a direct HTTPS tarball URL on a generic Google Cloud Storage bucket (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.1.1.tgz) rather than a registry name, bypassing npm registry scanning. On `npm install`, npm fetches and unpacks that tarball, and any lifecycle scripts it contains execute on the installer's machine. The bucket path `depenconf/` is consistent with dependency-confusion staging, and the package name evokes the widely-used pdf.js ecosystem while shipping no real implementation — a typosquat-shaped lure whose only effect is to route installs through the off-registry dropper. ## Source: ghsa-malware (3b26acfcfb972e07369dd35f509acb9463d9fced9d49fc6872abad284bb0a75d) 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.
