AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe unconditional remote executable script is a concrete externally controlled payload channel, and the bundled service-worker proxy infrastructure expands its browser-side interception capability. Lack of install hooks does not remove the runtime attack behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
User opens the package's index.html in a browser.
Impact
The remote host can supply arbitrary browser-side code; the service worker/proxy stack can mediate routed browsing requests and cookies.
Mechanism
Remote script execution plus service-worker proxy routing.
Attack narrative
The package is a browser application rather than a normal Node library. Its main HTML entry unconditionally loads JavaScript from c.vipersfutbol.com, so that external host controls code executed in every visitor's browser. Separate bundled code registers a service worker that claims browser clients and supplies a Scramjet-style proxy transport using a hard-coded WebSocket endpoint; its transport forwards proxied requests, connection headers, and cookies. No npm install hook is involved, but the runtime remote-code and traffic-interception surface is concrete.
AI rationale
The unconditional remote executable script is a concrete externally controlled payload channel, and the bundled service-worker proxy infrastructure expands its browser-side interception capability. Lack of install hooks does not remove the runtime attack behavior.

Decision evidence
public snapshotAI called this Malicious at 92.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.html loads and executes remote script https://c.vipersfutbol.com/script.js on page load.
- assets/boot-CVPGRFHh.js registers j6k3y8.js as a service worker.
- j6k3y8.js claims clients and routes matching fetches through _19vij0x.
- assets/boot-CVPGRFHh.js configures proxy transport wss://21baseballacademy.com/fairs/.
- ct1tl/csbzam.js forwards remote requests, WebSocket connections, headers, and cookies through the service-worker transport.
Evidence against
- package.json has no npm lifecycle hooks or executable bin.
- No Node filesystem, child-process, environment harvesting, or install-time behavior was found.
- KaTeX fonts and the WASM module are consistent with bundled browser dependencies.
