Republished package
This report shows the evidence for nottuff6@2.0.0, the only known version.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo install hook runs, but the declared entrypoint immediately delegates code execution to an unrelated remote domain and sets up persistent browser request interception. That is concrete malicious behavior for a republished npm package.
Static reason
One or more suspicious static signals were detected.
Trigger
A user opens `index.html` or serves the packaged web application.
Impact
The remote host can run arbitrary browser-side code in the page origin; the service worker can intercept routed requests.
Mechanism
Remote script execution plus service-worker-backed proxy routing.
Attack narrative
The package is a disguised, obfuscated browser application rather than a normal npm library. On opening its declared HTML entrypoint, it imports executable JavaScript from `c.vipersfutbol.com`; that host can change the payload without republishing the package. The local application concurrently registers a service worker that intercepts routed fetches and initializes a proxy transport to `wss://21baseballacademy.com/fairs/`. These unrelated remote control points, combined with heavy obfuscation and inconsistent package identity, form a concrete remote-payload execution chain.
AI rationale
No install hook runs, but the declared entrypoint immediately delegates code execution to an unrelated remote domain and sets up persistent browser request interception. That is concrete malicious behavior for a republished npm package.

Decision evidence
public snapshotAI called this Malicious at 96.0% confidence as Malware with low false-positive risk.
Evidence for block
- `index.html` loads executable remote script from `c.vipersfutbol.com` on page open.
- `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
- `j6k3y8.js` intercepts matching fetches and routes them through bundled proxy code.
- `assets/boot-CVPGRFHh.js` opens a Wisp WebSocket to `21baseballacademy.com`.
- Core application bundles, including `assets/ChatPage-zoA8Z6RX.js`, are deliberately obfuscated.
- Package identity is inconsistent: `nottuff6` ships a page titled `Lucide` plus unrelated sports domains.
Evidence against
- `package.json` has no preinstall, install, or postinstall hook.
- No inspected source showed Node child-process execution or local credential-file harvesting.
