AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo install-time Node compromise was found, but the runtime page automatically executes an unrelated third-party script and configures a service-worker proxy relay. The bundled obfuscation conceals this behavior rather than documenting an expected web-proxy feature.
Static reason
One or more suspicious static signals were detected.
Trigger
A user opens `index.html` in a browser.
Impact
An unrelated remote operator can execute arbitrary browser-side code; the configured proxy relay can observe or handle proxied browsing requests and cookies.
Mechanism
Remote-script execution plus service-worker web-proxy interception.
Attack narrative
The package is a browser application rather than a conventional npm library. When opened, its HTML imports an unrelated remote script, then its local bootstrap registers a service worker and configures a proxy transport to `wss://21baseballacademy.com/fairs/`. The worker routes matching fetches through proxy code that forwards requests and manages cookies. Because the remote script executes automatically and the browser proxy is hidden behind obfuscated bundles, this creates a concrete unconsented remote-code and traffic-interception surface for consumers who run the packaged page.
AI rationale

Decision evidence
public snapshotAI called this Malicious at 93.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` automatically loads `https://c.vipersfutbol.com/script.js`.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
- `assets/boot-CVPGRFHh.js` hard-codes `wss://21baseballacademy.com/fairs/`.
- `j6k3y8.js` routes intercepted fetches through `_19vij0x`.
- `ct1tl/jmqwjq.js` forwards proxied requests and cookies through its controller transport.
- `assets/ChatPage-zoA8Z6RX.js` and `assets/index-CJm_PfL2.js` are deliberately obfuscated.
Evidence against
- `package.json` has no `preinstall`, `install`, `postinstall`, or other lifecycle hook.
- The manifest entrypoint is `index.html`, not a Node executable.
- No package source showed Node filesystem, environment, child-process, or AI-agent configuration access.
