AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms automatic remote code execution and service-worker proxy persistence when the package entrypoint is opened. These behaviors are unrelated to the package identity and constitute a concrete malicious browser 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 the package's declared `index.html` entrypoint in a browser.
Impact
A remote host controls code executed in the page; the package also proxies routed requests and synchronizes cookies through its browser runtime.
Mechanism
Remote script execution plus persistent service-worker proxy routing.
Attack narrative
The package presents an HTML application as its npm main entrypoint. Loading it fetches and executes JavaScript from an unrelated external host, then its bundled boot code registers a service worker that intercepts selected requests and configures a Scramjet proxy over a remote WebSocket endpoint. This gives remote infrastructure control over page execution and enables persistent browser traffic mediation without an npm lifecycle hook.
AI rationale
Direct source inspection confirms automatic remote code execution and service-worker proxy persistence when the package entrypoint is opened. These behaviors are unrelated to the package identity and constitute a concrete malicious browser payload.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` loads remote JavaScript from `https://c.vipersfutbol.com/script.js` on page load.
- `assets/boot-CVPGRFHh.js` registers persistent service worker `j6k3y8.js` automatically.
- `j6k3y8.js` intercepts routed browser fetches and delegates them to `_19vij0x.route`.
- `assets/boot-CVPGRFHh.js` configures a proxy transport to `wss://21baseballacademy.com/fairs/`.
- `ct1tl/pap3do.js` injects scripts and proxies requests/cookies through the Scramjet runtime.
Evidence against
- `package.json` has no npm lifecycle scripts.
- No Node child-process, local credential-file harvesting, or install-time filesystem mutation was found.
