AI Security Review
scanned 3mo ago · by lpm-firewall-aiAlthough npm installation itself has no lifecycle hook, the declared `index.html` entrypoint immediately imports remote code and ships a service-worker proxy to an external transport. The source establishes a concrete runtime attack surface and offers no package-aligned justification.
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 or serves `index.html`; proxy behavior activates when the bundled boot controller is invoked.
Impact
The remote host can execute arbitrary browser code; the proxy can intercept routed browser requests and synchronize cookies.
Mechanism
Remote script execution plus service-worker proxy transport.
Attack narrative
The browser entrypoint directly executes code fetched from an unrelated remote host. Bundled code can register a persistent service worker that routes matching requests through a Scramjet-style proxy using a hard-coded external WebSocket endpoint and cookie synchronization. The obfuscated application bundle further conceals credential-related network functionality. This is a concrete remote browser-code and traffic-interception surface, not a harmless static asset bundle.
AI rationale
Although npm installation itself has no lifecycle hook, the declared `index.html` entrypoint immediately imports remote code and ships a service-worker proxy to an external transport. The source establishes a concrete runtime attack surface and offers no package-aligned justification.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` automatically loads remote code from `https://c.vipersfutbol.com/script.js`.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker and configures a proxy controller.
- The proxy boot code hard-codes `wss://21baseballacademy.com/fairs/` as its transport endpoint.
- `assets/ChatPage-zoA8Z6RX.js` is deliberately obfuscated while containing credential-oriented sign-in/sign-up API flows.
Evidence against
- `package.json` has no npm lifecycle scripts.
- No Node filesystem, child-process, or environment-variable harvesting was confirmed.
- No install-time execution path was found.
