AI Security Review
scanned 3mo ago · by lpm-firewall-aiAlthough installation itself has no lifecycle execution, the shipped browser entrypoint contains a concrete remote-code and request-interception chain. This exceeds a benign static-site package and warrants blocking.
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 or host renders `index.html` / opens the browser application.
Impact
A remote operator can change browser-executed code; routed requests and cookies can be handled by the proxy controller.
Mechanism
remote script execution plus service-worker request interception and proxying
Attack narrative
The package is a browser app rather than a normal npm library. On load, `index.html` imports a remotely hosted script from `c.vipersfutbol.com`, giving that host direct code execution in the app origin. Its bundled boot code then registers a service worker that intercepts requests for its proxy prefix and routes them through a controller configured with a WebSocket endpoint at `21baseballacademy.com`. The service-worker controller includes cookie forwarding logic. Obfuscation makes these capabilities needlessly opaque.
AI rationale
Although installation itself has no lifecycle execution, the shipped browser entrypoint contains a concrete remote-code and request-interception chain. This exceeds a benign static-site package and warrants blocking.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` loads and executes `https://c.vipersfutbol.com/script.js` without integrity protection.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker and configures a proxy transport to `wss://21baseballacademy.com/fairs/`.
- `j6k3y8.js` intercepts fetch events; `ct1tl/jmqwjq.js` forwards matching requests and cookies through controller RPC.
- The browser bundles are heavily obfuscated, including `assets/ChatPage-zoA8Z6RX.js`, concealing application behavior.
Evidence against
- `package.json` has no preinstall, install, postinstall, or other lifecycle script.
- No Node entrypoint, shell execution, local filesystem harvesting, or environment-variable access was found.
- The behavior activates when the HTML application is rendered, not when npm installs the package.
