MAL-2026-17456 Malicious code in @smwebserver/static (npm)

The package ships an effectively empty index.js and its only real content is a manifest-level dependency sourced from an arbitrary HTTPS URL rather than a registry version range: dependencies.ltidisafe is set to https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.7.9.tgz. On npm install, npm fetches that tarball and installs it, running any lifecycle scripts it contains, with no version pin, no integrity hash, and no signature check. The bucket host is not a publisher-controlled domain tied to this package, and the contents at that URL can be swapped at any time by whoever owns the bucket. The absence of lifecycle scripts in this package's own package.json does not mitigate the issue, because the fetched tarball's scripts are what execute. Installing this package therefore delegates full install-time code execution on the installer's machine to a mutable, off-registry source.

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.

The OpenSSF Package Analysis project identified '@smwebserver/static' @ 99.9.1 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.
