## Security analysis

### Published attack-surface review

- **Summary:** Opening index.html loads an obfuscated remote module. That module is given sw.js, whose install path imports further remote code into a service-worker context.

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

- **Impact:** Remote operator-controlled code can run in the page and service-worker scope for the deployed origin.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-06T03:33:12.906Z

### AI review details

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

- **Mechanism:** Obfuscated dynamic import and service-worker importScripts loader.

- **Rationale:** No install-time compromise is present, but the package is a staged remote-payload carrier with hidden loader URLs. The documented architecture explains its purpose but does not remove the runtime supply-chain risk.

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** sw.js obfuscates two importScripts URLs and loads the first available remote script., index.html obfuscates and dynamically imports a remote loader at page runtime., README.md calls this a static carrier and documents an external YuriRTC loader.

- **Evidence against:** package.json has no preinstall/install/postinstall hook., Packaged files contain no Node filesystem, shell, credential-harvesting, or exfiltration code., README.md describes the remote loader as the intended application architecture.

## 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@2.0.1/sw.js>)

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

Public source snippet (untrusted):

```javascript
L1: function _0x4754(){var _0x3f3bc2=['[redacted]','mti5mtaXtM1HvhPt','otuWodi4nfniv3DjEq','...
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.
