AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete remote-code-delivery chain activated by opening the package entrypoint, not merely a static heuristic. Lack of npm lifecycle hooks reduces install-time risk but does not mitigate browser-time arbitrary script execution.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
A user opens `index.html` in a browser.
Impact
The remote host can deliver arbitrary JavaScript in the viewer's browser context and the proxy can persist across routed page requests.
Mechanism
Remote script execution plus service-worker-backed proxy transport.
Attack narrative
The package is an HTML application rather than a normal library. When opened, its entrypoint directly loads executable JavaScript from an unrelated remote host, giving that host control of the browser session without an integrity pin. Its bundled boot code also installs a service worker and configures a proxy transport to a separate WebSocket endpoint, creating an opaque persistent routing layer. Obfuscation in the main application bundles further conceals behavior.
AI rationale
This is a concrete remote-code-delivery chain activated by opening the package entrypoint, not merely a static heuristic. Lack of npm lifecycle hooks reduces install-time risk but does not mitigate browser-time arbitrary script execution.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` loads and executes `https://c.vipersfutbol.com/script.js` on page open.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
- `j6k3y8.js` intercepts routed browser fetches through bundled proxy code.
- `assets/boot-CVPGRFHh.js` connects proxy transport to `wss://21baseballacademy.com/fairs/`.
- `assets/ChatPage-zoA8Z6RX.js` and `assets/index-CJm_PfL2.js` are heavily obfuscated, obscuring application behavior.
Evidence against
- `package.json` has no `preinstall`, `install`, or `postinstall` hook.
- The package entrypoint is browser-only `index.html`; no Node entry execution was found.
- No direct local credential-file harvesting or child-process invocation was established.
