AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe direct external script tag is an immediate, unpinned remote payload loader, not merely an inert library reference. Combined with automatic service-worker proxy setup and pervasive obfuscation, it establishes concrete malicious browser-runtime behavior.
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 the package's `index.html` in a browser.
Impact
The remote host can run arbitrary JavaScript in the page origin; the proxy stack can mediate routed browser traffic and cookies.
Mechanism
Remote script execution plus service-worker request interception.
Attack narrative
The package is a browser bundle whose HTML entrypoint automatically loads executable JavaScript from an unrelated external host. Its local boot code registers a service worker, and the included Scramjet components intercept and proxy routed fetch, cookie, and WebSocket activity. This creates an unconsented remote-code and traffic-mediation surface whenever the packaged page is opened, despite no npm install hook.
AI rationale
The direct external script tag is an immediate, unpinned remote payload loader, not merely an inert library reference. Combined with automatic service-worker proxy setup and pervasive obfuscation, it establishes concrete malicious browser-runtime behavior.

Decision evidence
public snapshotAI called this Malicious at 96.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` immediately executes remote `https://c.vipersfutbol.com/script.js`.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
- `j6k3y8.js` imports `ct1tl/jmqwjq.js` and intercepts routed fetch events.
- `assets/ChatPage-zoA8Z6RX.js` and `assets/index-CJm_PfL2.js` are heavily obfuscated browser application bundles.
- `ct1tl/pap3do.js` and `bfjdx/757lr8.js` implement Scramjet request, cookie, and WebSocket proxying.
Evidence against
- `package.json` has no npm lifecycle scripts.
- No Node filesystem, shell, environment-harvesting, or install-time execution was found.
- The shipped WASM/proxy components are browser-side rather than native install payloads.
