AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a browser application disguised as an npm package, with automatic remote script execution and proxy service-worker setup. Although no install hook or host-side harvesting was found, the confirmed runtime remote-code and interception surface warrants blocking.
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 serves or opens `index.html`; its module entry runs on page load.
Impact
An untrusted remote host receives arbitrary code execution in the page origin and the package installs browser request-routing infrastructure.
Mechanism
Remote script execution plus automatic service-worker proxy interception.
Attack narrative
The declared HTML entrypoint loads JavaScript from an unrelated third-party host without integrity controls. The bundled module then automatically registers a service worker that intercepts browser requests and configures a proxy WebSocket endpoint. This is active runtime behavior, not an inert asset: a consumer opening the package grants the remote script page-origin execution and enables bundled request-routing infrastructure. Obfuscated account/chat code adds concealment around credential-bearing browser requests.
AI rationale
This is a browser application disguised as an npm package, with automatic remote script execution and proxy service-worker setup. Although no install hook or host-side harvesting was found, the confirmed runtime remote-code and interception surface warrants blocking.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` executes third-party `https://c.vipersfutbol.com/script.js` on page load.
- `assets/index-CJm_PfL2.js` imports and invokes `bootController` at runtime.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker and configures proxy transport.
- `j6k3y8.js` intercepts routed fetch events; `ct1tl/pap3do.js` persists proxy cookies/state.
- `assets/boot-CVPGRFHh.js` connects proxy transport to `wss://21baseballacademy.com/fairs/`.
- `assets/ChatPage-zoA8Z6RX.js` is heavily obfuscated and implements credential-bearing account requests.
Evidence against
- `package.json` has no preinstall, install, postinstall, bin, or Node entrypoint.
- No source evidence of host filesystem access, environment harvesting, or AI-agent configuration mutation.
