AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms runtime remote-code loading and browser proxy/service-worker behavior, while no install-time Node execution exists. The hidden remote loader and obfuscated control path create a concrete malicious supply-chain payload.
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 `index.html`.
Impact
A remote host can change browser-side behavior without a package update; proxied traffic and cookies may be exposed to the external proxy infrastructure.
Mechanism
Remote browser code execution plus service-worker-backed web proxying.
Attack narrative
The package is presented as an npm package but installs a browser application as its main entrypoint. On page load, it runs an external script from `c.vipersfutbol.com`, then its bundled code registers a service worker and configures a Scramjet/libcurl proxy using `wss://21baseballacademy.com/fairs/`. The service-worker stack routes requests and manages proxied cookies, creating a concealed, remotely mutable browsing-control path.
AI rationale
Source inspection confirms runtime remote-code loading and browser proxy/service-worker behavior, while no install-time Node execution exists. The hidden remote loader and obfuscated control path create a concrete malicious supply-chain payload.

Decision evidence
public snapshotAI called this Malicious at 94.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` executes remote `https://c.vipersfutbol.com/script.js` on page load.
- `assets/boot-CVPGRFHh.js` automatically registers `j6k3y8.js` as a service worker.
- The boot code routes proxy traffic through `wss://21baseballacademy.com/fairs/`.
- `ct1tl/csbzam.js` and `ct1tl/pap3do.js` proxy requests and persist proxied cookies.
- `assets/index-CJm_PfL2.js` and `assets/ChatPage-zoA8Z6RX.js` are deliberately obfuscated.
Evidence against
- `package.json` has no preinstall, install, postinstall, or prepare scripts.
- No Node filesystem, shell, or environment-harvesting code was confirmed.
- The service-worker/proxy components are browser-only and activate when the HTML app loads.
