AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package automatically transmits the local username during installation to a fixed external endpoint. This is concrete install-time data exfiltration, so the release should be blocked.
Static reason
One or more suspicious static signals were detected.
Trigger
Runs automatically during package installation through the preinstall lifecycle script.
Impact
Discloses the local account username to an unrelated external destination without installer consent.
Mechanism
The script substitutes the output of whoami into a wget request query parameter.
Attack narrative
During installation, the preinstall hook runs whoami and sends its output as a query parameter in an HTTP request to 8.8.8.8. This exposes the installing user's username to a fixed external destination without consent.
AI rationale
The package automatically transmits the local username during installation to a fixed external endpoint. This is concrete install-time data exfiltration, so the release should be blocked.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The preinstall script runs wget to http://8.8.8.8/ and puts the output of whoami in the request query.
- The README describes the package as a dependency confusion proof of concept.
Evidence against
- The index.js entry point only exports a function that logs a demo message. It does not add runtime behavior beyond that.
