MacChanger

Introduction

Every device has a unique MAC address assigned by the manufacturer. When connecting to a router, this MAC address can be logged and potentially reveal your device identity.

MacChanger helps in spoofing or changing the MAC address temporarily.

Installation

sudo apt install macchanger

Usage

1. List all interfaces:

   ip link show
   

2. Change MAC address randomly:

   sudo macchanger -r ens33
   

   Replace ens33 with your interface name (for example, eth0, wlan0).

3. Set a specific MAC address:

   sudo macchanger -m 00:11:22:33:44:55 ens33
   

4. Restore the original MAC address:

   sudo macchanger -p ens33

Notes

• The change is temporary and will revert back after a system reboot.

• Useful for avoiding tracking on WiFi networks and during ethical hacking operations.

• Some networks may not allow spoofed MACs, so usage may vary.
