## What is MAL-2026-5446?

MAL-2026-5446 is a malicious package in housecall-ui, published on 9 Jun 2026. 

### Official description

housecall-ui@99.9.1 is a hollow npm package (empty description, empty author, index.js exports an empty object) whose sole runtime dependency is declared as an HTTPS tarball URL pointing at a third-party Google Cloud Storage bucket: `"ltidisafe": "https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.9.8.tgz"` (package.json line 10). On `npm install`, npm fetches whatever bytes currently reside at that GCS URL and executes any lifecycle scripts (preinstall/install/postinstall) inside the resulting tarball. The bucket is not the npm registry, is not a documented publisher infrastructure for any vendor, is unpinned by hash, and is mutable by whoever controls it — meaning the installer cannot audit or guarantee what code will run. The package's name is brand-adjacent to HouseCall Pro and the version is artificially inflated to 99.9.1, the canonical pattern of a dependency-confusion lure designed to outrank an internal private package of the same name in mixed-resolution environments. The surrounding package contributes no functionality; its only effect on install is to sideload `ltidisafe` from attacker-mutable infrastructure.

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.

## What should I do about MAL-2026-5446?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
