## Security analysis

### Published attack-surface review

- **Summary:** Opening the packaged static site loads remotely supplied code. The service worker imports an unpinned @latest script from public CDNs.

- **Trigger:** A user serves and opens index.html in a browser.

- **Impact:** Remote loader updates can change browser-side behavior without a package-version change.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-06T03:19:28.211Z

### AI review details

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

- **Mechanism:** Obfuscated runtime remote-code loader

- **Rationale:** The remote, unpinned code-loading chain is concrete and concealed by obfuscation, but source inspection does not prove a specific malicious payload or install-time compromise.

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

- **Network endpoints:** unpkg.com, cdn.jsdelivr.net

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 93.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** sw.js obfuscates a service-worker loader that calls importScripts on remote sources., Decoded sw.js strings reference unpkg.com and cdn.jsdelivr.net @edurocks-group/loader@latest., index.html dynamically imports the same obfuscated remote loader at runtime., README says the package is a YuriRTC carrier, conflicting with its math description.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., No local credential harvesting, shell execution, or filesystem access was found.

## Public findings

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

Package declares npm scripts.

### 2. High: Obfuscated Payload Loader
- **Category:** Source
- **Confidence:** 86.0%
- **Path:** sw.js
- **Public source:** [View source](<https://unpkg.com/learnmathedu@2.0.0/sw.js>)

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

Public source snippet (untrusted):

```javascript
L1: function _0x5d90(_0x11f24b,_0x5ed86a){_0x11f24b=_0x11f24b-0xa3;var _0x391781=_0x3917();var _0x5d90b3=_0x391781[_0x11f24b];if(_0x5d90['VcjRiW']===undefined){var _0x20a21a=function(_...
L2: /*[redacted]*/
```

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

Package source contains high-entropy string patterns.

### 4. 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.
