AI Security Review

scanned 3h ago · by lpm-firewall-ai

Opening `index.html` executes a remotely hosted script without package-local integrity control. The browser app also registers a service worker that intercepts routed fetches and connects its proxy transport to a third-party WebSocket endpoint.

Static reason
One or more suspicious static signals were detected.
Trigger
A consumer opens the packaged `index.html` in a browser.
Impact
Remote content can execute in the page origin; proxy traffic and cookies for routed sites pass through the configured transport.
Mechanism
Remote script execution plus service-worker-backed web proxy with cookie synchronization.
Rationale
The package contains a concrete automatic remote-code and traffic-interception surface when its HTML entrypoint is opened. That behavior is high risk and materially unrelated to a normal npm package, but it is not install-time host malware.

OSV Corroboration

OpenSSF Malicious Packages via OSV
Summary
Malicious code in nottuff12 (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 (f2d8e844ddfa5618437dae6e8f35d3148e6077a0f24a76ede26dc158cf86f638) 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 94.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for block
  • `index.html` automatically loads `https://c.vipersfutbol.com/script.js`.
  • `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
  • `j6k3y8.js` claims clients and routes every matching fetch through `_19vij0x.route`.
  • `assets/boot-CVPGRFHh.js` configures a proxy transport to `wss://21baseballacademy.com/fairs/`.
  • `ct1tl/pap3do.js` proxy code rewrites requests and syncs cookies.
Evidence against
  • `package.json` has no `preinstall`, `install`, `postinstall`, or other lifecycle scripts.
  • `main` is `index.html`; install does not automatically execute browser assets.
  • No inspected source showed child-process use, local credential-file harvesting, or AI-agent configuration writes.
