AI Security Review

scanned 2h ago · by lpm-firewall-ai

Opening `index.html` executes an unpinned third-party script and browser proxy application. The application can register a service worker to route browser requests and connect to a remote WebSocket proxy.

Static reason
One or more suspicious static signals were detected.
Trigger
A user opens the packaged HTML application in a browser.
Impact
Remote script content can execute in the page context; proxied browsing requests and cookies are handled by the application proxy.
Mechanism
Remote script loading plus service-worker-mediated web proxying.
Rationale
No install-time compromise is present, but the obfuscated browser app automatically loads remote code and installs a request-routing proxy. That is a concrete, unresolved user-runtime risk inappropriate for an npm dependency.

OSV Corroboration

OpenSSF Malicious Packages via OSV
Summary
Malicious code in abuden25 (npm)
Details
The tarball ships `auto-publish.sh`, a script that republishes the same payload under ~100 distinct npm names (`ishowfeet1`-`ishowfeet20`, `nottuff1`-`nottuff30`, `abuden*`, `imillegal*`, `ratelimitsucks*`, etc/) by rewriting `package.json.name` and running `npm publish --silent` in a loop — namespace-spam infrastructure shipped inside the package itself. The package's declared `main` is `sw.js`, a browser Service Worker (`importScripts('./8cfc2/hgshm.js')`, `self.addEventListener('install'|'activate'|'fetch'|'message')`) that throws immediately if loaded from Node. The shipped assets are a heavily obfuscated Ultraviolet/bare-mux web-proxy frontend with an `index.html` themed as "Riverbend Tutoring" that hides a popunder redirect to `https://abdct.com/` on click/keydown/touchstart. `package.json` declares no `preinstall`/`install`/`postinstall`/`prepare` hooks, and `require('ishowfeet9')` from Node fails before any code runs, so a Node installer experiences no auto-execution. The harm is registry abuse (mass-publication of a misleading name family) and a browser-side proxy/popunder served to whoever later loads these static assets — not installer-side compromise. Routing to human review for namespace-abuse adjudication. ## Source: ghsa-malware (425e2aa0d915a3547f6468283ca985c6c3cbee226d90ef177bfa64759013cade) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Decision evidence

public snapshot
AI called this Suspicious at 86.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for block
  • `index.html` auto-loads remote `https://c.vipersfutbol.com/script.js`.
  • `assets/boot-CVPGRFHh.js` registers a service worker and configures a proxy.
  • The proxy connects to `wss://21baseballacademy.com/fairs/`.
  • `j6k3y8.js` routes matching browser fetches through the service worker.
  • Primary application bundles are deliberately obfuscated.
  • `package.json` disguises a browser application as an npm package.
Evidence against
  • `package.json` has no preinstall, install, postinstall, or prepare hook.
  • No Node filesystem, process, shell, or child-process execution was found.
  • No confirmed credential harvesting or exfiltration chain was identified.
  • The WASM and proxy runtime are used by the browser proxy stack, not npm install.
