Malicious code in page-info-service (npm)
What this malware does
[email protected] 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.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for page-info-service (version 99.9.1).
If you installed it — respond
Remove page-info-service from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If page-info-service was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks page-info-service-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
