AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms executable remote code loading and a persistent browser request-interception proxy tied to unrelated hosts. This is concrete harmful behavior despite the absence of npm lifecycle hooks.
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 `index.html` or serves the package as a web application.
Impact
An external operator can execute browser code and observe or relay proxied application traffic, including submitted credentials handled by the obfuscated UI.
Mechanism
Remote script execution plus service-worker interception and remote proxy transport.
Attack narrative
The package is a disguised, obfuscated web application rather than a normal npm library. When opened, it executes a remote third-party script, registers a service worker, and routes matching browser requests through a WebSocket proxy. Its obfuscated chat/account code processes username, password, and captcha values, creating a concrete credential-interception and remote-code-execution surface.
AI rationale
Source inspection confirms executable remote code loading and a persistent browser request-interception proxy tied to unrelated hosts. This is concrete harmful behavior despite the absence of npm lifecycle hooks.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` loads and executes `https://c.vipersfutbol.com/script.js`.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
- `assets/boot-CVPGRFHh.js` routes traffic through `wss://21baseballacademy.com/fairs/`.
- `ct1tl/jmqwjq.js` intercepts matching fetches and forwards URL, headers, and body.
- `assets/ChatPage-zoA8Z6RX.js` is heavily obfuscated and handles username/password/captcha requests.
- The manifest disguises this browser application as `abuden24` with only `index.html` as main.
Evidence against
- `package.json` has no lifecycle scripts.
- No Node filesystem, process, or child-process execution was found.
- The observed behavior activates when the packaged page is opened, not during npm install.
