MAC Address Spoofer

A command-line tool to spoof your network interface's MAC address on Linux systems.

What is a MAC Address?

A Media Access Control (MAC) address is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This identifier is used in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

Changing your MAC address can be useful for:

• Privacy - Prevent tracking across networks
• Testing - Simulate different network devices
• Bypassing restrictions - Some networks filter by MAC address

MAC Address Structure

A MAC address is a 12-digit hexadecimal number (6 bytes), typically represented in colon-hexadecimal notation (e.g., 00:1A:2B:3C:4D:5E).

Bytes	Name	Description
First 3 bytes	OUI (Organizationally Unique Identifier)	Identifies the manufacturer
Last 3 bytes	NIC (Network Interface Controller)	Device-specific identifier

Features

• 🎲 Random MAC generation - Generate safe, locally-administered unicast addresses
• 🏭 Vendor spoofing - Mimic devices from Samsung, Apple, Intel, Microsoft, Huawei, Google, or Cisco
• 🖥️ Interactive TUI - Easy to use text interface
• ⚡ Auto mode - Non-interactive operation for scripts
• 🔧 CI mode - Designed for automated testing pipelines

Compatibility

The tool is compatible with Linux distributions only.

Tested on:

• Ubuntu - 16.04.7, 18.04.6, 20.04.6, 22.04.5, 24.04.2
• Debian - 8, 9, 10, 11, 12
• Kali - 2021.4a, 2022.4, 2023.4, 2024.4, 2025.1
• Raspbian - 8, 9, 10, 11, 12

Installation

Via pip (recommended)

pip install macspoofer

From source

chmod +x setup.sh
sudo ./setup.sh

Usage

Find Your Interface Name

ifconfig -a
# or
ip link show

Interactive Mode (TUI)

sudo -E macspoofer -i <interface>
# or
sudo -E python3 main.py -i <interface>

Auto Mode (Non-Interactive)

sudo -E macspoofer -i <interface> --auto
# or
