## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 5 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list

- **Analysis source:** AI Security Review (lpm-firewall-ai)

At browser runtime, the HTML loader and service worker fetch remote loader metadata and execute remotely supplied JavaScript. The remote URLs are obfuscated, so no exact endpoint is statically visible.

## Security analysis

### Published attack-surface review

- **Summary:** At browser runtime, the HTML loader and service worker fetch remote loader metadata and execute remotely supplied JavaScript. The remote URLs are obfuscated, so no exact endpoint is statically visible.

- **Trigger:** Opening the packaged index.html in a browser and registering its service worker

- **Impact:** A remote operator can change code executed in the page and service-worker contexts after publication.

- **Evidence paths:** package.json, index.html, sw.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T00:36:46.375Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Obfuscated remote module loading via dynamic import and importScripts

- **Rationale:** This is a concrete unpinned remote execution path hidden by obfuscation, but the inspected source does not establish an explicitly malicious payload or install-time attack. Treat it as a staged payload carrier requiring a warning.

- **Files touched:** index.html, sw.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 93.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** index.html is an obfuscated browser loader that dynamically imports remote modules., sw.js synchronously fetches a remote version manifest, then importScripts a remotely selected worker., Remote code sources and Firebase configuration are intentionally hidden by obfuscation., README.md identifies this as a YuriRTC static carrier, inconsistent with the math package name.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., Only index.html and sw.js are shipped; no filesystem, credential, or child-process behavior was found., README.md describes the remote loader/service-worker design and bounded network-state UI behavior.

## Public findings

### 1. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 2. Medium: Network
- **Category:** Source
- **Confidence:** 75.0%

Package source references network APIs.

### 3. High: Obfuscated Payload Loader
- **Category:** Source
- **Confidence:** 86.0%
- **Path:** sw.js
- **Public source:** [View source](<https://unpkg.com/learnmathedu@2.0.2/sw.js>)

Source contains an obfuscated payload loader that reconstructs and executes hidden code.

Public source snippet (untrusted):

```javascript
L1: (function(_0x514f23,_0x554ff1){var _0x4791b3={_0x1ba2e2:0x2c9,_0x23dac5:0x2d3,_0x4b6412:0x2d8,_0x143a3c:0x2ca,_0x1818d4:0x2c6,_0x139f8b:0x2c2,_0x3e2393:0x2dc,_0x1e5768:0x2d0,_0x5a1...
L2: /*[redacted]*/
```

### 4. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 5. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 70.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.
