## Security analysis

### Published attack-surface review

- **Summary:** Opening index.html dynamically loads remote JavaScript; its service worker also imports remote code. The remote loader can change behavior independently of the package tarball.

- **Trigger:** A user deploys or opens index.html in a browser.

- **Impact:** Remote code executes in the page and service-worker contexts of a deployed site.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T02:35:33.549Z

### AI review details

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

- **Mechanism:** Obfuscated dynamic imports and service-worker importScripts from CDN URLs.

- **Rationale:** The package contains a concrete remote-code loading surface but no npm lifecycle execution or confirmed malicious local payload. This is a staged payload carrier requiring a warning rather than a block.

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

- **Network endpoints:** https://unpkg.com/@edurocks-group/loader@0.2.12/dist/bundle/sw.js, https://cdn.jsdelivr.net/npm/@edurocks-group/loader@0.2.12/dist/bundle/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 at runtime., sw.js uses importScripts with two obfuscated remote fallback URLs., Remote loader controls the page boot and service-worker behavior., Package purpose/name differs from the YuriRTC/edurocks loader references.

- **Evidence against:** package.json has no preinstall/install/postinstall hooks., No local credential harvesting, filesystem access, shell execution, or exfiltration code was found., Remote loading is activated only when the published HTML is opened, not by npm installation.

## 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@1.2.0/sw.js>)

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

Public source snippet (untrusted):

```javascript
L1: function _0x8314(_0x270ddc,_0x3bb67d){_0x270ddc=_0x270ddc-0xbf;var _0x5d4236=_0x5d42();var _0x831469=_0x5d4236[_0x270ddc];if(_0x8314['QgUuMt']===undefined){var _0x7d73c8=function(_...
```

### 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.
