📊 Attack Flow Diagram

1. Step 1: User lands on the phishing page (natrajstonex.co.in) disguised as a Roundcube Webmail login portal
2. Step 2: User enters credentials into the login form
3. Step 3: Credentials are captured via JavaScript event handlers and form submission logic
4. Step 4: `http_post()` function sends credentials to the server via AJAX POST requests
5. Step 5: Server-side script processes and exfiltrates the credentials to the attacker's storage or command-and-control (C2) server
