AI Security Review

scanned 4h ago · by lpm-firewall-ai

Opening the declared HTML entry immediately loads an unrelated remote script with arbitrary browser-code execution authority. The app also registers a service worker that can proxy selected browser requests through a remote WebSocket transport.

Static reason

One or more suspicious static signals were detected.

Trigger

User opens `index.html` or serves the package as its declared entrypoint.

Impact

Remote operators can execute code in the visitor's origin and potentially observe or alter proxied application traffic.

Mechanism

remote script execution plus service-worker-backed web proxy

Attack narrative

The package is presented as an npm package but declares an HTML page as its entrypoint. Loading that page executes a remote script from `c.vipersfutbol.com` without integrity pinning. Its bundled proxy bootstrap registers a service worker and routes selected requests through a WebSocket endpoint at `21baseballacademy.com`; the worker forwards request URLs, headers, and bodies to its controller. This is a concrete remote-code and traffic-interception surface, not merely an obfuscation signal.

Rationale

Source inspection confirms immediate third-party remote code loading and a service-worker proxy transport. No install hook is needed for the package to create a harmful runtime attack surface when its declared entrypoint is used.

Decision evidence

public snapshot

AI called this Malicious at 94.0% confidence as Malware with low false-positive risk.

Evidence for block

`index.html` executes remote `https://c.vipersfutbol.com/script.js` on page load.
`assets/boot-CVPGRFHh.js` registers `j6k3y8.js` service worker.
`ct1tl/jmqwjq.js` intercepts routed fetches and forwards request bodies/headers through its controller.
`assets/boot-CVPGRFHh.js` configures proxy WebSocket `wss://21baseballacademy.com/fairs/`.
`assets/ChatPage-zoA8Z6RX.js` is heavily obfuscated and implements username/password sign-in requests.

Evidence against

`package.json` has no npm lifecycle scripts.
No Node entrypoint or filesystem/child-process harvesting was found.
The KaTeX font blobs and WASM runtime are consistent with bundled browser assets.
