Summary

Malicious code in localization-lib (npm)

localization-lib@99.9.1 is an empty shell package: index.js is module.exports = {} and package.json has no description or author. Its dependencies declares "ltidisafe": "https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.0.1.tgz", resolving a transitive dependency directly from a third-party Google Cloud Storage bucket rather than the npm registry. On npm install, npm fetches and installs that opaque tarball and executes any lifecycle hooks it declares on the installer's machine. The version 99.9.1 is the canonical outranking-version pattern used in dependency-confusion attacks to override a legitimate internally-named package, and the URL path literally contains the token depenconf. The package has no functional purpose other than smuggling this off-registry dependency into the installer's environment.

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.
