" To hide your MAC address completely in Linux, you can use MAC address spoofing to temporarily change your network interface’s MAC address. This prevents your real hardware MAC from being exposed on the network.

Using macchanger (Recommended)

Install macchanger :

sudo apt install macchanger  # Debian/Ubuntu/Kali
sudo pacman -S macchanger    # Arch Linux
  • Randomize MAC (recommended for anonymity):
sudo ip link set dev wlan0 down
sudo macchanger -r wlan0
sudo ip link set dev wlan0 up
  • Set a specific spoofed MAC:
sudo macchanger --mac=AA:BB:CC:DD:EE:FF wlan0
  • Restore original MAC:
sudo macchanger -p wlan0

Note: Always bring the interface down before changing the MAC, then bring it back up.

Automate Spoofing on Boot

To ensure MAC is changed every time you connect:

  • Use systemd or udev rules to run macchanger at boot.
  • Example systemd service (/etc/systemd/system/macspoof@.service ):
[Unit]
Description=MAC Address Change %I
Wants=network-pre.target
Before=network-pre.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device

[Service]
Type=oneshot
ExecStart=/usr/bin/macchanger -r %I
ExecStart=/usr/bin/ip link set dev %I up

[Install]
WantedBy=multi-user.target

Enable with: sudo systemctl enable macspoof@wlan0.service

Use Tools Like anonym8 (for full anonymity)

The anonym8 tool hides both IP and MAC address:

git clone https://github.com/hiroshim/anonym8.git
cd anonym8
chmod +x install.sh
sudo ./install.sh
anonym8 start  # Starts Tor + MAC spoofing
anonym8 start mac  # Changes MAC address

Important: MAC spoofing is temporary and resets on reboot unless automated. It does not hide your MAC from local network traffic if you're on the same LAN, but it prevents tracking via MAC address on public networks.

For maximum privacy , combine MAC spoofing with Tor , VPN , and network manager settings that disable MAC randomization tracking.
