## Security analysis

### Published attack-surface review

- **Summary:** Using the React component triggers an external license-revocation request and local IndexedDB caching. The remote result can disable the component, but no code execution or data exfiltration was confirmed.

- **Trigger:** Mounting the Reaction component in a browser.

- **Impact:** A third-party endpoint can remotely prevent the component from rendering; the opaque implementation leaves residual audit risk.

- **Evidence paths:** index.js, license/verify.d.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-09-04T10:42:39.883Z

### AI review details

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

- **Mechanism:** Obfuscated browser-side license verification with a remote revocation list.

- **Rationale:** This is suspicious because a heavily obfuscated animation package contains remotely controlled license enforcement and browser fingerprint-like logic. Static inspection found no concrete malicious execution, collection, or install-time behavior, so blocking is not justified.

- **Files touched:** index.js

- **Network endpoints:** https://api.npoint.io/f63d2269d3d045f8cdc3

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for:** The 53 KB single-line index.js is deliberately obfuscated, which prevents straightforward auditing of its browser behavior., The package includes a license-revocation check that performs a remote lookup and caches results in IndexedDB., When the Reaction component mounts, it verifies a license and can suppress the advertised animation; the lookup endpoint is api.npoint.io., The runtime derives a browser-specific identifier from navigator properties and stores it on window, although no transmission of that value was found.

- **Evidence against:** package.json has no lifecycle scripts and declares only React as a peer dependency., Static inspection found no child-process use, shell commands, environment reads, filesystem access, eval/Function execution, or dynamic module loading., The remote response is parsed as a revocation list rather than executed as code., No credential harvesting, payload download, persistence, or destructive behavior was found.

## Public findings

### 1. Medium: Network
- **Category:** Source
- **Confidence:** 75.0%

Package source references network APIs.

### 2. High: Obfuscated Payload Loader
- **Category:** Source
- **Confidence:** 86.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/react-flying-reaction@2.0.5/index.js>)

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

Public source snippet (untrusted):

```javascript
L1: const _0x20f026=_0x262e;(function(_0x3d0ef3,_0x3721ec){const _0x296719=_0x262e,_0x5daf05=_0x3d0ef3();while(!![]){try{const _0x438827=parseInt(_0x296719(0x159))/0x1*(-parseInt(_0x29...
```

### 3. High: Obfuscated
- **Category:** Supply Chain
- **Confidence:** 100.0%

Package source appears deliberately obfuscated.

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

Package source contains high-entropy string patterns.

### 5. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 6. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 7. Low: No License
- **Category:** Manifest
- **Confidence:** 80.0%

Package manifest does not declare a clear license.

### 8. Medium: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 86.0%
- **Path:** license/verify.d.ts
- **Public source:** [View source](<https://unpkg.com/react-flying-reaction@2.0.5/license/verify.d.ts>)

The package includes a license-revocation check that performs a remote lookup and caches results in IndexedDB.

Public source snippet (untrusted):

```typescript
* Full check: signature + expiry, then a lookup against REVOKED_LIST_URL —
 * a base64-encoded JSON array of revoked key IDs. No server/database
 * needed. The result is cached in IndexedDB for REVOCATION_CACHE_TTL_MS so
 * most mounts don't hit the network at all.
```
