AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo install hook executes during npm installation, but the declared browser entrypoint contains a concrete third-party remote-code execution path and an opaque request-interception stack. That is sufficient to block publication as a malicious runtime payload.
Static reason
One or more suspicious static signals were detected.
Trigger
A user opens or serves `index.html` in a browser.
Impact
The remote host can execute arbitrary code in the page origin; the bundled proxy can mediate routed requests and cookies.
Mechanism
Remote JavaScript execution plus browser request/cookie interception.
Attack narrative
The package is a browser application packaged as an npm artifact. Loading its declared `main` HTML immediately imports unpinned code from `c.vipersfutbol.com`, allowing that external operator to run arbitrary script under the hosting origin. Local bundles establish a Scramjet-style proxy service worker that intercepts routed fetches and synchronizes cookies, increasing the value of page-level code execution. This is runtime behavior rather than npm install-time execution.
AI rationale
No install hook executes during npm installation, but the declared browser entrypoint contains a concrete third-party remote-code execution path and an opaque request-interception stack. That is sufficient to block publication as a malicious runtime payload.

Decision evidence
public snapshotAI called this Malicious at 90.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` loads executable JavaScript from `https://c.vipersfutbol.com/script.js`.
- `index.html` automatically loads proxy and controller bundles on page open.
- `j6k3y8.js` installs a fetch-intercepting service worker.
- `ct1tl/jmqwjq.js` proxies matching requests and relays cookies through controlled clients.
- `assets/ChatPage-zoA8Z6RX.js` is heavily obfuscated, preventing transparent review of its runtime behavior.
Evidence against
- `package.json` has no preinstall, install, postinstall, or other lifecycle hook.
- No Node filesystem, shell, credential-harvesting, or package-install-time execution was found in inspected entry files.
- Font blobs and the local WASM module are consistent with the shipped browser proxy application.
