AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect inspection confirms runtime remote-code loading and a service-worker proxy/cookie transport, not merely scanner heuristics. Although no npm lifecycle hook runs at install, the browser entrypoint creates an unconsented remote payload and sensitive browsing-data attack surface.
Static reason
One or more suspicious static signals were detected.
Trigger
A user opens the package's `index.html` browser entrypoint and activates the bundled proxy flow.
Impact
Remote code executes in the page context; proxied browsing data and cookies can be handled by the package-controlled proxy path.
Mechanism
remote script loading plus service-worker HTTP/cookie proxying
Attack narrative
The package is not a normal npm library: its main entry is a web page that runs a remote script from an unrelated host. Its bundled proxy stack registers a service worker, intercepts routed requests, handles cookie synchronization, and sends proxy traffic to a separate remote WebSocket endpoint. The remote script is an unpinned payload channel, while the proxy path creates a concrete route for handling users' proxied web sessions.
AI rationale
Direct inspection confirms runtime remote-code loading and a service-worker proxy/cookie transport, not merely scanner heuristics. Although no npm lifecycle hook runs at install, the browser entrypoint creates an unconsented remote payload and sensitive browsing-data attack surface.

Decision evidence
public snapshotAI called this Malicious at 93.0% 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.
- `j6k3y8.js` routes matching fetches through bundled proxy code.
- `assets/boot-CVPGRFHh.js` configures proxy transport `wss://21baseballacademy.com/fairs/`.
- `ct1tl/csbzam.js` and `ct1tl/pap3do.js` proxy requests and synchronize cookies through the service-worker controller.
- Core application bundles are deliberately obfuscated, hindering payload audit.
Evidence against
- `package.json` has no preinstall, install, postinstall, prepare, or bin hook.
- The package contains no Node filesystem, shell, process-environment, or child-process execution path.
- Service-worker/proxy setup is browser-runtime behavior, not npm install-time execution.
