AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a republished npm package whose HTML entry embeds remote executable code and activates a service-worker traffic proxy to unrelated external infrastructure. The runtime behavior is concrete and high-impact despite the absence of install hooks.
Static reason
One or more suspicious static signals were detected.
Trigger
Opening `index.html` in a browser.
Impact
A remote operator can supply code and observe or alter proxied browser traffic in the page's controlled scope.
Mechanism
Remote script execution plus service-worker traffic interception and WebSocket proxying.
Attack narrative
The browser entry loads a third-party executable script, then startup code invokes `bootController()`. That routine registers a service worker which intercepts fetches and configures Scramjet/libcurl proxy components to use `wss://21baseballacademy.com/fairs/`; related controller code forwards cookie operations. This gives remote infrastructure both an unpinned code-execution path and a browser-traffic proxy path when the entry page is opened.
AI rationale
This is a republished npm package whose HTML entry embeds remote executable code and activates a service-worker traffic proxy to unrelated external infrastructure. The runtime behavior is concrete and high-impact despite the absence of install 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 executable third-party script from `c.vipersfutbol.com`.
- `assets/index-CJm_PfL2.js` dynamically imports and invokes `bootController()` during app startup.
- `assets/boot-CVPGRFHh.js` registers local service worker `j6k3y8.js` and connects to `wss://21baseballacademy.com/fairs/`.
- `j6k3y8.js` intercepts fetch events and routes matching requests through `_19vij0x`.
- `ct1tl/csbzam.js` and `ct1tl/pap3do.js` implement proxy routing and cookie forwarding.
- `package.json` has no lifecycle hook; activation occurs when its HTML entry is opened.
Evidence against
- No `preinstall`, `install`, or `postinstall` script is declared.
- No Node child-process, filesystem-harvesting, or AI-agent configuration mutation was found.
