Description

The npm package '@fcsmc/commercial-analytics' version 99.9.1 is identified as malicious. It contains an inert stub but declares a dependency via a direct HTTPS tarball URL, which bypasses npm registry controls and installs attacker-controlled code. The package communicates with a domain linked to malicious activity. Installing this package can lead to full system compromise, and all secrets and keys on the affected system should be rotated immediately.

Impact

Installation of this package results in full compromise of the affected system. Attackers may gain complete control, potentially accessing all stored secrets and keys. The package's malicious payload bypasses npm integrity and version controls, enabling execution of arbitrary code. Removal of the package alone may not eliminate all malicious components, as the system could have been persistently compromised.

Defensive guidance

Remove the '@fcsmc/commercial-analytics' package immediately. Rotate all secrets and keys from a separate, uncompromised system. Due to the potential full system compromise, conduct a thorough security assessment and remediation beyond package removal. Monitor for any signs of persistent malicious activity.

Summary

The '@fcsmc/commercial-analytics' npm package (version 99.9.1) is malicious. It uses a dependency declaration that points to a direct HTTPS tarball URL rather than a registry version, allowing arbitrary code execution during installation by fetching attacker-controlled payloads. The package itself is a stub with no legitimate functionality and is designed as a dependency-confusion lure. It communicates with known malicious domains, indicating active malicious behavior. Systems with this package installed should be considered fully compromised.
