AI Security Review

scanned 2h ago · by lpm-firewall-ai

Opening the package's HTML entrypoint loads a remote script and starts an obfuscated service-worker proxy. The proxy can intercept routed browser requests, retain cookies, and relay traffic through a third-party WebSocket endpoint.

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` in a browser.
Impact
Creates a browser-side proxy/control surface and executes unauditable third-party code; credential theft is not directly confirmed.
Mechanism
Service-worker traffic interception with remote WebSocket proxying.
Rationale
This is not a conventional npm library: it is an obfuscated browser proxy application with automatic service-worker setup and remote runtime code. The concrete risky capability warrants a warning, while lack of confirmed theft or install-time behavior does not justify a block.

OSV Corroboration

Advisory
MAL-2026-10356
Source
OpenSSF Malicious Packages via OSV
Summary
Malicious code in nottuff30 (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 (47161ed9ed6a628062720b39942fc2d70f1725d0adbd253499fce5f7360cd3f7) 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 93.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for block
  • `index.html` executes `https://c.vipersfutbol.com/script.js` at page load.
  • `assets/index-CJm_PfL2.js` obfuscates an immediate `bootController()` call.
  • `assets/boot-CVPGRFHh.js` registers `j6k3y8.js` as a service worker.
  • `j6k3y8.js` claims clients and routes browser fetch events.
  • `assets/boot-CVPGRFHh.js` sends proxy traffic to `wss://21baseballacademy.com/fairs/`.
  • `ct1tl/pap3do.js` injects proxy hooks and persists proxied cookies.
Evidence against
  • `package.json` has no preinstall, install, postinstall, or bin hook.
  • No Node child-process, filesystem, or environment harvesting path was found.
