## Vishing (Voice Phishing)

Hacking over the phone.

### The Deepfake Era
*   AI can now clone voices with 3 seconds of audio.
*   "Hi Mom, I'm in jail, send money." (Grandparent Scam).
*   "Hi Process Team, this is the CEO, approve the transaction."

### Techniques
1.  **Caller ID Spoofing**: Making the phone show "Internal IT Helpdesk".
2.  **Background Noise**: Playing office sounds (typing, printers) to verify the lie.

### Defense
*   **Callback Policy**: "I need to verify. I will hang up and call you back at your internal extension listed in the directory."
    *   If they resist ("No, I am on my cell!"), it is a scam.
*   **Challenge-Response**: "What is the daily code word?"
