Opening index.html loads a remote loader; its service worker also loads remote code selected at runtime. The packaged artifacts are obfuscated and act as a carrier rather than a self-contained math package.

## Security analysis

### Published attack-surface review

- **Summary:** Opening index.html loads a remote loader; its service worker also loads remote code selected at runtime. The packaged artifacts are obfuscated and act as a carrier rather than a self-contained math package.

- **Trigger:** User opens the packaged HTML in a browser and permits service-worker/runtime execution.

- **Impact:** A mutable remote payload can execute in the page and service-worker contexts.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-10T21:39:29.353Z

### AI review details

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

- **Mechanism:** runtime remote-code loading through dynamic import and importScripts

- **Rationale:** This is a runtime staged-payload carrier with concealed remote execution, but source inspection found no concrete install-time malware or direct exfiltration. Warn rather than block.

- **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 an obfuscated remote loader., sw.js fetches a remote version then calls importScripts., README identifies it as a YuriRTC static carrier, not math software., Runtime code and endpoints are obscured by obfuscation.

- **Evidence against:** package.json has no install lifecycle hook., No package code reads local files, environment, or credentials at install., No concrete credential or data exfiltration is visible in packaged files.

## 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@2.1.2/sw.js>)

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

Public source snippet (untrusted):

```javascript
L1: function _0x9a7e5e(_0x332ddc,_0x1c2211){return _0xb259(_0x332ddc- -0x73,_0x1c2211);}(function(_0x4b373d,_0x2a84d1){var _0x50e5b4={_0x36c24b:0x2be,_0x409bbb:0x2b9,_0xb5f95d:0x2be,_0...
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.
