MAL-2026-5431 Malicious code in @webd-infra/query-designer-domain (npm)

The package's package.json declares its only dependency ltidisafe as a direct tarball URL: https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.8.3.tgz. On npm install, npm fetches this tarball from a Google Cloud Storage bucket (not the npm registry) and runs whatever lifecycle scripts it contains. The bucket owner — not an npm publisher with registry-side accountability — controls exactly which bytes get executed, and the tarball contents at that URL can change at any time. Supporting indicators: the package has empty author and description fields, the version 99.9.1 is the canonical dependency-confusion sentinel used in research/PoC packages, and the bucket path segment is the literal string depenconf. The package itself ships no other runtime code — its sole effect on installers is resolving and executing this off-registry tarball.

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.
