    SIMPLE ALGORITHM

    Goal  -> Check if MAC address was changed.

    Steps:

    1. Execute and read ifconfig.

    2. Read the mac address from the output.

    3. Check if MAC in ifconfig is what the user requested.

    4. Print appropriate message.

    To find the MAC address, we can use the Pythex tool.

    EX: Python Code 

    #!/usr/bin/env python
    
    import subprocess
    import optparse
    import re
    
    def get_arguments():
        parser = optparse.OptionParser()
        parser.add_option("-i", "--interface", dest="interface", help="Interface to change its MAC address")
        parser.add_option("-m", "--mac", dest="new_mac", help="New MAC address")
        (options, arguments) = parser.parse_args()
        if not options.interface:
            parser.error("[-] Please specify an interface, use --help for more info.")
        elif not options.new_mac:
            parser.error("[-] Please specify a new mac, use --help for more info.")
        return options
    
    def change_mac(interface, new_mac):
        print("[+] Changing MAC address for " + interface + " to " + new_mac)
        subprocess.call(["ifconfig", interface, "down"])
        subprocess.call(["ifconfig", interface, "hw", "ether", new_mac])
        subprocess.call(["ifconfig", interface, "up"])
    
    def get_current_mac(interface):
        ifconfig_result = subprocess.check_output(["ifconfig", interface])
        mac_address_search_result = re.search(r"ww:ww:ww:ww:ww:ww", ifconfig_result)
    
        if mac_address_search_result:
            return mac_address_search_result.group(0)
        else:
            print("[-] Could not read MAC address.")
    
    options = get_arguments()
    
    current_mac = get_current_mac(options.interface)
    print("Current MAC = " + str(current_mac))
    
    change_mac(options.interface, options.new_mac)
    
    current_mac = get_current_mac(options.interface)
    if current_mac == options.new_mac:
        print("[+] MAC address was successfully changed to " + current_mac)
    else:
        print("[-] MAC address did not get changed.")

    Execute the following command to test the Python code:

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

     

    相信未来 - 该面对的绝不逃避,该执著的永不怨悔,该舍弃的不再留念,该珍惜的好好把握。
