AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis package has no install hook, but its declared browser entrypoint contains a concrete, automatically activated remote-code and traffic-interception chain. The external executable script is unpinned and unrelated to a normal npm library interface.
Static reason
One or more suspicious static signals were detected.
Trigger
User opens `index.html` in a browser.
Impact
A remotely controlled script can execute in the page origin; routed browser requests may be mediated through the configured proxy transport.
Mechanism
Remote script execution plus service-worker traffic interception and remote proxying.
Attack narrative
The browser entrypoint immediately fetches and executes a script from `c.vipersfutbol.com`, leaving payload behavior under a remote party’s control. Its own boot code installs a service worker that intercepts fetches and configures a Scramjet-style proxy using `wss://21baseballacademy.com/fairs/`; the obfuscated chat bundle also uses WebSockets. This is an active browser-side remote execution and traffic-routing chain, not merely a bundled static asset.
AI rationale
This package has no install hook, but its declared browser entrypoint contains a concrete, automatically activated remote-code and traffic-interception chain. The external executable script is unpinned and unrelated to a normal npm library interface.

Decision evidence
public snapshotAI called this Malicious at 94.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` auto-loads remote `https://c.vipersfutbol.com/script.js`.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
- `j6k3y8.js` intercepts fetch events and routes selected requests.
- `assets/boot-CVPGRFHh.js` configures proxy transport `wss://21baseballacademy.com/fairs/`.
- `assets/ChatPage-zoA8Z6RX.js` is heavily obfuscated and opens WebSockets.
Evidence against
- `package.json` contains no npm lifecycle scripts.
- No Node filesystem, environment-harvesting, or child-process chain was confirmed.
- The WebAssembly loader in `assets/proxy-runtime-1NyFshf9.js` is browser-oriented.
