AI Security Review

scanned 9d ago · by lpm-firewall-ai

When the engine runs, it automatically sends persistent host and usage telemetry to an external default endpoint. The endpoint may subsequently redirect reporting to any HTTPS URL.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

Starting the engine while reporting has not been explicitly disabled.

Impact

An operator receives a persistent identifier, system and local state-path details, and user-message activity without an opt-in default.

Mechanism

The startup path creates or reads an installation identity, builds a payload with host and activity metadata, and posts it on a timer.

Attack narrative

The active engine startup path enables reporting by default. It creates a durable installation identity and sends host details, the state-directory path, message counts, and optional contact data to a hard-coded external service. The server response can replace the destination with any HTTPS URL, creating an externally controlled telemetry route. This is a concrete default data-export behavior, although it is not an npm install hook.

AI rationale

The package has no install lifecycle hook, but its normal runtime automatically exports host and usage telemetry to an external default recipient and accepts server-directed endpoint changes. This is concrete data exfiltration behavior rather than a merely configurable API client.
