AI Security Review
scanned 26d ago · by lpm-firewall-aiThe suspicious static hints do not establish an attack: the manifest has no install lifecycle hook, and the entrypoint’s observed dynamic imports support the package’s captcha widget functionality. The flagged runtime shim only imports node:module and exports an empty module.
Static reason
One or more suspicious static signals were detected.
Trigger
Loading the browser entrypoint and finding a widget with a site key, unless start mode is manual.
Impact
No malicious effect was established from the inspected source.
Mechanism
Dynamically imports the declared Prosopo detector and common modules, then calls the detector prefetch function.
AI rationale
The suspicious static hints do not establish an attack: the manifest has no install lifecycle hook, and the entrypoint’s observed dynamic imports support the package’s captcha widget functionality. The flagged runtime shim only imports node:module and exports an empty module.
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 points to dist/index.js and lists build, typecheck, and test scripts without an install lifecycle hook.
- The declared runtime dependencies are Prosopo captcha components and related utilities.
- dist/index.js prefetches Prosopo detector modules only when a site key is present and start mode is not manual.
- The flagged runtime shim only imports node:module and exports an empty module.
