AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo install-time behavior was found, but the shipped browser entrypoint loads a remote third-party script and configures an opaque proxied browsing stack that can handle request data. These behaviors are concrete enough to treat the package as malicious rather than benign bundled application code.
Static reason
One or more suspicious static signals were detected.
Trigger
A user opens or serves `index.html` in a browser.
Impact
Remote infrastructure can receive proxied browsing traffic within the proxy route scope; the externally loaded script executes with the page's origin privileges.
Mechanism
runtime-loaded remote script plus service-worker request proxy
Attack narrative
The package is a browser application, not a normal library. Its entrypoint loads an opaque third-party script immediately, then an obfuscated bundle invokes a controller bootstrap. That bootstrap installs a service worker which intercepts selected fetches and forwards request metadata and body through a configured WebSocket proxy at `21baseballacademy.com`. This creates a concrete, non-package-aligned remote execution and traffic-relay surface when the app is opened, though it does not execute during npm install.
AI rationale
No install-time behavior was found, but the shipped browser entrypoint loads a remote third-party script and configures an opaque proxied browsing stack that can handle request data. These behaviors are concrete enough to treat the package as malicious rather than benign bundled application code.

Decision evidence
public snapshotAI called this Malicious at 91.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` loads third-party script `https://c.vipersfutbol.com/script.js` on page load.
- `assets/boot-CVPGRFHh.js` registers a service worker and configures a proxy transport to `wss://21baseballacademy.com/fairs/`.
- `j6k3y8.js` routes matching browser fetches through `ct1tl/jmqwjq.js`; that worker forwards request URL, headers, and body to the controller.
- `assets/index-CJm_PfL2.js` dynamically imports and invokes `bootController()` at runtime.
- `assets/ChatPage-zoA8Z6RX.js` is deliberately obfuscated, obscuring the web application's behavior.
Evidence against
- `package.json` has no `scripts`, lifecycle hooks, or `bin` entry.
- The manifest main is `index.html`; npm installation alone does not execute the browser assets.
- No Node filesystem, subprocess, credential-environment harvesting, or install-time mutation chain was confirmed.
- The `.wasm`, proxy runtime, and dynamic require are used by the browser proxy stack rather than a demonstrated native payload.
