## What is MAL-2026-5158?

MAL-2026-5158 is a malicious package in page-info-service, published on 2 Jun 2026. 

### Official description

page-info-service@99.9.1 ships an empty stub (`index.js` is `module.exports = {}`) with placeholder author/description metadata and an unusually high 99.9.1 version designed to win semver resolution against an internal package name. Its sole effect is a `dependencies` entry that pulls `ltidisafe` from an external HTTPS tarball at `https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.9.3.tgz` — not from the npm registry. On `npm install`, npm fetches and installs that tarball and runs whatever lifecycle scripts and code it contains. The tarball is hosted on a third-party Google Cloud Storage bucket under a path (`depenconf/`) that explicitly suggests dependency-confusion tooling; its contents are mutable by the bucket owner, there is no integrity hash, no version pinning to a trusted registry, and no relation to any stated package purpose. This matches the canonical dependency-confusion off-registry-dropper pattern.

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 'page-info-service' @ 99.9.1 (npm) as malicious.

It is considered malicious because:

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

## What should I do about MAL-2026-5158?

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