MAL-2026-13976 Malicious code in check-audit (npm)

[email protected] is an otherwise empty package (no author, no description, no meaningful code) whose only effect on install is to pull a dependency named ltidisafe from an arbitrary Google Cloud Storage URL: https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.6.5.tgz. This URL is not the npm registry and is not tied to any declared publisher of check-audit. The tarball contents are mutable and bypass registry-side scanning; whatever code and lifecycle scripts it ships execute in the installer's node_modules on npm install. The version number (99.9.1) and hollow package contents are consistent with a lure/dropper whose sole purpose is to pull attacker-controllable code into the dependency tree at install time.

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.
