commonweb-rewardsnpm

commonweb-rewards ships an empty index.js and declares a single dependency ltidisafe whose version spec is a direct URL to a tarball on a non-publisher Google Cloud Storage bucket: https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.5.5.tgz. On npm install, npm fetches and installs that tarball into the consumer's node_modules; any lifecycle scripts it declares (preinstall/install/postinstall) execute on the installer's machine, and the package's runtime code is loaded whenever the consumer requires it. The bytes at that URL are mutable and controlled by the bucket owner, not the npm publisher, and are not pinned by hash or signature. Combined with the hollow main entry, the sole effect of installing commonweb-rewards is to resolve and run whatever code is currently hosted at that GCS URL. The depenconf path component and the shell-package shape (empty main + single out-of-registry URL dependency) are consistent with a dependency-confusion / smuggling loader.

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 'commonweb-rewards' @ 99.9.1 (npm) as malicious.

It is considered malicious because:

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