AI Security Review

scanned 3h ago · by lpm-firewall-ai

Opening `index.html` automatically executes an attacker-controlled remote script in the page origin. The bundled application also contains obfuscated fingerprinted network logic and a service-worker proxy stack.

Static reason

One or more suspicious static signals were detected.

Trigger

A user opens or serves the package HTML entrypoint.

Impact

The remote host can execute arbitrary JavaScript in the page context and access page-visible data, storage, and network capabilities.

Mechanism

Unpinned third-party script execution with obfuscated browser-side request logic.

Attack narrative

The package is a browser application rather than a conventional library. Its entrypoint automatically fetches and executes a script from an unrelated external domain without integrity pinning, giving that host arbitrary code execution in every page serving the package. Obfuscated application chunks perform fingerprint-tagged requests, while bundled service-worker code intercepts routed fetches and handles cookies. There is no install-time hook, but the runtime remote-code-execution surface is concrete.

Rationale

Direct source inspection confirms automatic execution of an unpinned external script plus obfuscated fingerprinted network behavior. This is a concrete browser-side remote payload execution chain, not merely a scanner heuristic.

Decision evidence

public snapshot

AI called this Malicious at 93.0% confidence as Malware with low false-positive risk.

Evidence for block

`index.html` loads an unpinned third-party script from `https://c.vipersfutbol.com/script.js`.
The remote script executes automatically whenever the package's HTML entrypoint is opened.
`assets/AiPage-CFg0RGso.js` and `assets/ChatPage-zoA8Z6RX.js` are deliberately obfuscated and make fingerprint-tagged requests.
`j6k3y8.js` installs a service-worker fetch interceptor.
`ct1tl/jmqwjq.js` and `ct1tl/pap3do.js` implement routed proxying, cookie handling, and cached responses.

Evidence against

`package.json` has no preinstall, install, or postinstall lifecycle hook.
No Node child-process, local filesystem harvesting, or environment-variable harvesting was confirmed.
