MAC ADDRESS

Media Access Control
- Permanent
- Physical
- Unique
Assigned by manufacturer

WHY CHANGE THE MAC ADDRESS

1.Increase anonymity

2.Impersonate other devices

3.Bypass filters

Change the MAC Address manually.

ifconfig

ifconfig eth0 down

ifconfig eth0 hw ether 00:11:22:33:44:55

ifconfig eth0 up

ifconfig

MAC_CHANGER USING A PYTHON MODULE TO EXECUTE SYSTEM COMMANDS

The subprocess module contains a number of functions.
These functions allow us to execute system commands.
Commands depend on the OS which executes the script.

Refer to the Python Documentation:?https://docs.python.org/3/library/subprocess.html

Simple sample:

#!/usr/bin/env python

import subprocess

subprocess.call("ifconfig",shell=True)

The Python script to change the MAC Address:

#!/usr/bin/env python

import subprocess

subprocess.call("ifconfig eth0 down",shell=True)
subprocess.call("ifconfig eth0 hw ether 00:11:22:33:44:66",shell=True)
subprocess.call("ifconfig eth0 up",shell=True)

?It works.

The updated Python script to change the MAC address using variables.

#!/usr/bin/env python

import subprocess

interface = "eth0"
new_mac = "00:11:22:33:44:77"

print("[+] Changing MAC address for " + interface + " to " + new_mac)

subprocess.call("ifconfig " + interface + " down",shell=True)
subprocess.call("ifconfig " + interface + " hw ether " + new_mac,shell=True)
subprocess.call("ifconfig " + interface + " up",shell=True)

Run the script successfully.

The updated Python script using the user‘s input.

#!/usr/bin/env python

import subprocess

interface = input("interface > ")
new_mac = input("new MAC > ")

print("[+] Changing MAC address for " + interface + " to " + new_mac)

subprocess.call("ifconfig " + interface + " down",shell=True)

?Run the new scripts successfully.

Enhance the security of the Python script by changing the use of the call function.

#!/usr/bin/env python

import subprocess

interface = raw_input("interface > ")
new_mac = raw_input("new MAC > ")

print("[+] Changing MAC address for " + interface + " to " + new_mac)

subprocess.call(["ifconfig",interface,"down"])
subprocess.call(["ifconfig","hw","ether",new_mac])
subprocess.call(["ifconfig","up"])

?Run the script successfully and more secure.

Update the Python script to handle command-line arguments.

Use the module Parser:?https://docs.python.org/2/library/optparse.html

#!/usr/bin/env python

import subprocess
import optparse

parser = optparse.OptionParser()

parser.add_option("-i","--interface",dest="interface",help="Interface to change its MAC address")

parser.parse_args()

interface = raw_input("interface > ")
new_mac = raw_input("new MAC > ")

print("[+] Changing MAC address for " + interface + " to " + new_mac)

subprocess.call(["ifconfig","up"])

Initializing the variables based on the command arguments.

#!/usr/bin/env python

import subprocess
import optparse

parser = optparse.OptionParser()

parser.add_option("-i",help="Interface to change its MAC address")
parser.add_option("-m","--mac",dest="new_mac",help="New MAC address")

(options,arguments) = parser.parse_args()

interface = options.interface
new_mac = options.new_mac

print("[+] Changing MAC address for " + interface + " to " + new_mac)

subprocess.call(["ifconfig","up"])

Execute the following commands.

python mac_changer.py --interface eth0 --mac 00:11:22:33:44:55

or 

python mac_changer.py -i eth0 -m 00:11:22:33:44:55
