**Automatically detect packages vulnerable to Dependency Confusion attacks while browsing**

## 📋 About

**Dependency Confusion Hunter** is a Chrome extension that passively monitors web pages for packages that may be vulnerable to Dependency Confusion attacks. It analyzes JavaScript files and source maps to identify internal/private dependencies that don't exist in public registries (npm, PyPI).

### 🎯 What is Dependency Confusion?

Dependency Confusion is a supply chain attack where an attacker publishes a malicious package to a public registry with the same name as an internal/private package. If the package manager isn't configured correctly, it may download the malicious public package instead of the private one.

```javascript
// Example: Internal package that doesn't exist on npm
import { auth } from 'company-internal-auth';  // ⚠️ Vulnerable!

// An attacker can publish 'company-internal-auth' to npm
// and compromise systems that try to install it
```
