Spoof your WiFi's MAC Address automatically on boot

What does this do?

spoofmac randomises your hardware MAC Address & assigns a (semi) random MAC to your network card.

Why?

This is as good an explanation as any.

How does it work?

There are two parts to this repo. A .service file & a shell script.

• The service file makes sure that the MAC Address is assigned at boot etc.

• The script

  • uses predefined MAC prefixes & randomly generates the NIC specific octets
  • automatically recognises the WiFi interface name
  • applies the (semi) random MAC address to the interface

Install

• Download the repo

❯ git clone https://github.com/frost19k/spoofmac.git

• Run the install script

❯ cd spoofmac
❯ sudo ./install.sh

• Alternatively

  • Copy the systemd .service file to a systemd unit search path
  • Copy the script to a location of your choosing
  • Modify the service file & point to the absolute path of the script
  • Enable the service

• Restart your system

Notes

• I would recommend using known OUI prefixes. Fully random MACs may cause issues.
  • You can find OUI MAC prefixes here
  • I recommend using at least 5 different prefixes
• If autodetect interface name fails you can always manually define the name in the .service file.
