AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is not a normal executable npm library: its HTML entry silently imports unrelated remote code and establishes browser interception/proxy infrastructure. The absence of install hooks does not mitigate the runtime remote-code execution path.
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` entry.
Impact
Remote host operators can run code in the page origin and alter routed browser requests at runtime.
Mechanism
Remote script execution plus service-worker-backed browser traffic interception/proxying.
Attack narrative
When the package's declared HTML entry is opened, it automatically loads and executes a remote script from `c.vipersfutbol.com`, whose contents are not pinned or present in the package. The bundled code is additionally obfuscated, uses runtime code construction, registers a service worker, and configures routing through a remote WebSocket proxy. This creates a concrete remote-code and browser-traffic control surface without user consent.
AI rationale
This is not a normal executable npm library: its HTML entry silently imports unrelated remote code and establishes browser interception/proxy infrastructure. The absence of install hooks does not mitigate the runtime remote-code execution path.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` automatically loads unpinned remote code from `https://c.vipersfutbol.com/script.js`.
- `assets/index-CJm_PfL2.js` is heavily obfuscated and constructs code with `new Function(...)`.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker at runtime.
- `j6k3y8.js` and `ct1tl/jmqwjq.js` claim clients and intercept routed fetch requests.
- `assets/boot-CVPGRFHh.js` configures a proxy WebSocket endpoint at `wss://21baseballacademy.com/fairs/`.
- No package lifecycle hook is needed: opening the declared HTML entry triggers the remote loader.
Evidence against
- `package.json` contains no `preinstall`, `install`, `postinstall`, or `prepare` scripts.
- No Node filesystem, shell, environment-harvesting, or native executable usage was found in inspected sources.
- The bundled proxy/service-worker code has an apparent web-proxy purpose, but it does not justify the unrelated remote script loader.
