Summary
Malicious code in sso-users-detection (npm)

sso-users-detection@99.9.1 is a hollow package (main exports {}, empty author/description, inflated 99.9.1 version) whose sole effect on install is to pull a runtime dependency named ltidisafe from a raw tarball URL on a third-party Google Cloud Storage bucket (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.3.1.tgz) instead of the npm registry. On npm install, npm fetches and installs that tarball, whose contents and lifecycle scripts (preinstall/install/postinstall) are entirely controlled by whoever owns the bucket and bypass npm registry scanning. The depenconf path segment, the inflated version number, and the empty index are consistent with a dependency-confusion lure whose only purpose is to smuggle attacker-controlled code into installer dependency trees.

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.
