AI Security Review
scanned 26d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook, and the inspected entrypoint’s imports and conditional prefetch align with a CAPTCHA widget. The scanner’s runtime bridge hint is not evidence of malicious behavior in the inspected source.
Static reason
One or more suspicious static signals were detected.
Trigger
Importing the entrypoint; prefetch additionally requires a site key.
Impact
No concrete malicious effect was established from the inspected source.
Mechanism
The entrypoint loads widget modules and, when activated, dynamically imports Prosopo packages to prefetch detector data.
AI rationale
The manifest has no install lifecycle hook, and the inspected entrypoint’s imports and conditional prefetch align with a CAPTCHA widget. The scanner’s runtime bridge hint is not evidence of malicious behavior in the inspected source.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json has build and test scripts but no install lifecycle hook.
- dist/index.js imports the package's virtual runtime and local widget modules; its dependency imports are Prosopo packages.
- The optional detector prefetch runs only when a site key is present and calls the Prosopo frictionless package.
