AI Security Review
scanned 4mo ago · by lpm-firewall-aiThis is not an ordinary npm library: its only entrypoint is an HTML app that loads unpinned remote code and installs a service worker to proxy traffic to unrelated remote infrastructure. No install hook is needed for the concrete runtime remote-code and traffic-exfiltration chain.
Static reason
One or more suspicious static signals were detected.
Trigger
User opens `index.html` in a browser.
Impact
Remote operator can change page behavior and receive proxied browser requests, headers, referrers, and bodies.
Mechanism
Remote script execution plus service-worker browser traffic proxying.
Attack narrative
When a user opens `index.html`, it executes arbitrary code fetched from `c.vipersfutbol.com`, then loads a service-worker-backed proxy stack. The bootstrap connects to `wss://21baseballacademy.com/fairs/`; the service worker serializes routed requests with URL, referrer, headers, and body to its controller. This creates a remote-controlled browser proxy and exposes user traffic after activation.
AI rationale
This is not an ordinary npm library: its only entrypoint is an HTML app that loads unpinned remote code and installs a service worker to proxy traffic to unrelated remote infrastructure. No install hook is needed for the concrete runtime remote-code and traffic-exfiltration chain.

Decision evidence
public snapshotAI called this Malicious at 96.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` loads remote `https://c.vipersfutbol.com/script.js` on page load.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` and connects to `wss://21baseballacademy.com/fairs/`.
- `ct1tl/jmqwjq.js` service worker forwards intercepted request URL, referrer, headers, and body to a controller.
- `j6k3y8.js` activates the request-routing service worker.
- Browser bundles are heavily obfuscated, concealing this proxy behavior.
Evidence against
- `package.json` has no npm lifecycle scripts.
- No Node filesystem, shell, credential-file, or AI-agent configuration mutation was found.
- The local WASM/proxy bundles implement browser-side routing rather than install-time execution.
