Macchanger is a tool in Kali Linux used to change or spoof the MAC address of a network interface. The MAC address (Media Access Control address) is a unique identifier assigned to a network interface controller (NIC) for communication on a network. Changing your MAC address can enhance your privacy or help you bypass certain network restrictions.

Why Use Macchanger?

• Privacy: By changing your MAC address, you can hide your device’s original hardware identity on a network, making it harder to track.
• Bypassing Network Restrictions: Some networks may use MAC address filtering, only allowing specific MAC addresses to connect. Spoofing your MAC address can help you bypass such restrictions.
• Testing Purposes: In penetration testing or security auditing, changing the MAC address is often used to simulate different devices or to test network security.
