AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms browser-side remote payload execution and a persistent service-worker proxy path, not merely scanner-observed obfuscation. Although installation itself has no lifecycle hook, the shipped entrypoint establishes a concrete malicious runtime chain.
Static reason
One or more suspicious static signals were detected.
Trigger
User opens `index.html` or serves the package as a web app.
Impact
Remote operator can alter client-side behavior; routed browsing traffic and cookies pass through the bundled proxy control path.
Mechanism
Remote script execution plus service-worker-based traffic interception and proxying.
Attack narrative
The package presents an HTML file as its npm main entry. When opened, it loads an unpinned remote script from `c.vipersfutbol.com`, then includes an obfuscated browser application with a service-worker proxy stack. The boot module registers `j6k3y8.js`, configures a WSS endpoint at `21baseballacademy.com`, and routes browser requests through Scramjet-style rewriting and cookie synchronization. This is an unconsented remote-control and traffic-interception capability unrelated to a normal npm library.
AI rationale
Source inspection confirms browser-side remote payload execution and a persistent service-worker proxy path, not merely scanner-observed obfuscation. Although installation itself has no lifecycle hook, the shipped entrypoint establishes a concrete malicious runtime chain.

Decision evidence
public snapshotAI called this Malicious at 96.0% 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` configures `wss://21baseballacademy.com/fairs/`.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
- `j6k3y8.js` claims clients and intercepts routed fetches.
- `ct1tl/pap3do.js` handles proxy requests and synchronizes proxied cookies.
- `assets/ChatPage-zoA8Z6RX.js` is heavily obfuscated, concealing browser-side behavior.
Evidence against
- `package.json` has no preinstall, install, or postinstall hook.
- No Node filesystem, shell, or credential-harvesting API was found in reviewed sources.
