AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe unconditional remote script is sufficient concrete remote-code execution behavior at browser runtime; its behavior is not pinned or package-contained. Absence of lifecycle hooks reduces install-time risk but does not negate the page-load payload channel.
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 the package main entry, `index.html`.
Impact
Remote code can inspect or alter page state, access origin-scoped browser data available to the page, and make network requests as the application.
Mechanism
Automatic third-party remote script execution with a browser proxy/service-worker runtime.
Attack narrative
The package is a browser application disguised as an npm package with `index.html` as its main entry. When opened, it unconditionally loads and executes JavaScript from `c.vipersfutbol.com`, giving that external host a mutable post-publication payload channel. The package also ships obfuscated application code and a service-worker/Scramjet proxy stack capable of intercepting routed browser requests and handling cookies. No install hook is present, but the automatic remote executable dependency is a concrete runtime supply-chain attack surface.
AI rationale
The unconditional remote script is sufficient concrete remote-code execution behavior at browser runtime; its behavior is not pinned or package-contained. Absence of lifecycle hooks reduces install-time risk but does not negate the page-load payload channel.

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 executable code from `https://c.vipersfutbol.com/script.js`.
- `index.html` makes the HTML application the package main entry and loads the remote script on page open.
- `assets/ChatPage-zoA8Z6RX.js` is heavily obfuscated and contains runtime `fetch` and `WebSocket` use.
- `j6k3y8.js` defines a service worker that routes matching fetches through bundled proxy logic.
- `ct1tl/pap3do.js` implements Scramjet proxying, cookie synchronization, cache, and request/WebSocket transport.
Evidence against
- `package.json` has no preinstall, install, postinstall, or other lifecycle hooks.
- No Node filesystem, child-process, environment-harvesting, or npm credential access was found in inspected package sources.
- The bundled proxy and service-worker code is browser runtime code rather than install-time execution.
