AI Security Review

scanned 14d ago · by lpm-firewall-ai

The preinstall script only enforces the declared Node version requirement. The flagged message and media code performs package-aligned WhatsApp media handling, with no confirmed malicious behavior in the inspected paths.

Static reason

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

Trigger

Package installation runs the preinstall hook; media operations run when called by the application.

Impact

The inspected behavior does not establish an attack surface.

Mechanism

The hook checks the Node version, while the inspected message paths download WhatsApp media and generate video thumbnails.
