AI Security Review

scanned 17h ago · by lpm-firewall-ai

The manifest activates an install-time tracker that collects identifying project context and sends it to a package-selected collector without installer consent. This is an unconsented installation beacon, so the package should be blocked.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Installing the package through npm runs its postinstall hook.

Impact

Installation and project metadata can leave the installer environment automatically.

Mechanism

The hook gathers installation context, including available CI project details, adds a client identifier, and POSTs the telemetry payload to the configured collector.

Attack narrative

On npm installation, the postinstall hook runs the tracker. It gathers installation context, including CI repository and workflow details when available, and sends a package-installed event with a client identifier to fixed telemetry endpoints. The source shows no consent check on this install-time send.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

package.json runs the installation tracker automatically from its postinstall hook.
The tracker detects installation context, including CI repository and workflow names, and sends it without an installer consent check.
The telemetry payload includes a client identifier and installation details; the tracker POSTs it to fixed Desktop Commander telemetry endpoints.
