AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms automatic third-party code execution and a service-worker proxy with unrelated remote infrastructure. The absence of npm lifecycle hooks limits install-time impact but does not remove the concrete browser runtime attack surface.
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
User opens the package's `index.html` in a browser.
Impact
Remote code executes in the page context and proxied browser traffic/cookies can be relayed through attacker-controlled infrastructure.
Mechanism
Remote script loader plus persistent service-worker request proxy.
Attack narrative
The package is presented as a static HTML entrypoint, but opening it automatically loads arbitrary JavaScript from `c.vipersfutbol.com`. Its local boot code registers a service worker that intercepts requests under the proxy route and connects the proxy layer to `wss://21baseballacademy.com/fairs/`; the controller also transfers cookies and request bodies through its transport. This is an unconsented remote-payload and browser-traffic relay chain, not a normal npm library behavior.
AI rationale
Direct source inspection confirms automatic third-party code execution and a service-worker proxy with unrelated remote infrastructure. The absence of npm lifecycle hooks limits install-time impact but does not remove the concrete browser runtime attack surface.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` automatically executes `https://c.vipersfutbol.com/script.js`.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
- `j6k3y8.js` intercepts routed fetches and forwards request metadata/body to its controller.
- `assets/boot-CVPGRFHh.js` configures proxy transport `wss://21baseballacademy.com/fairs/`.
- `ct1tl/csbzam.js` proxies requests/WebSockets and synchronizes cookies.
- `assets/ChatPage-zoA8Z6RX.js` is a 1 MB obfuscated runtime bundle with network APIs.
Evidence against
- `package.json` has no `preinstall`, `install`, or `postinstall` script.
- No Node executable, filesystem harvesting, or AI-agent configuration mutation was found.
