Simple ARP Spoofer to Perform a Man-in-the-Middle using Scapy. The python script gets the MAC address of the victim and victim's gateway MAC address. Then the script uses the MAC address of the computer the script is running from to spoof the victim's gateway address to perform the man-in-the-middle attack.

Note: The script uses the IPv4 forward queue which is limited to Linux.

python arp_spoofer.py -v <victim_ip> -g <gateway_ip>

python arp_spoofer.py --help

arp_spoofer.py [-h] [-v VICTIMIP] [-g GATEWAYIP]

optional arguments:
  -h, --help            show this help message and exit
  -v VICTIMIP, --victim VICTIMIP
                        Victim IP Address
  -g GATEWAYIP, --gateway GATEWAYIP
                        Default Gateway IP Address
