## 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)

Opening the shipped HTML dynamically imports a remote loader; its service worker loads remote worker code. This is a mutable remote-payload execution surface, not an install-time attack.

## Security analysis

### Published attack-surface review

- **Summary:** Opening the shipped HTML dynamically imports a remote loader; its service worker loads remote worker code. This is a mutable remote-payload execution surface, not an install-time attack.

- **Trigger:** A user serves or opens index.html and the browser initializes its service worker.

- **Impact:** Remote CDN content can control the web application at runtime.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T00:39:49.514Z

### AI review details

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

- **Mechanism:** Obfuscated runtime remote module and service-worker loading

- **Rationale:** Source establishes a staged, mutable remote-code carrier but not concrete credential theft, host mutation, or install-time malicious behavior. Warn so consumers do not treat the package as self-contained or immutable.

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** index.html dynamically imports obfuscated remote loader sources at runtime., sw.js synchronously fetches a worker version then importScripts remote code., README.md says this is a YuriRTC static carrier and release output is deliberately obfuscated., Remote loader version is resolved at runtime, allowing mutable third-party code.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., Package contains only index.html, sw.js, and README.md., No local credential harvesting, filesystem access, shell execution, or destructive behavior was found.

## 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@2.1.1/sw.js>)

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

Public source snippet (untrusted):

```javascript
L1: (function(_0x39d6eb,_0x30e0de){var _0x81ce62={_0x2370d:0x7,_0x4be597:0x11,_0x576447:0xb,_0x20671f:0x2,_0x1ee3c0:0x8,_0x33adf1:0x15,_0x2ad1ec:0x3,_0x3119f1:0x5},_0x419c39={_0x5072f6...
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.
