ARP spoofing is a type of attack in which a malicious actor sends falsified ARP (Address Resolution Protocol) messages over a local area network. This results in the linking of an attacker’s MAC address with the IP address of a legitimate computer or server on the network. Once the attacker’s MAC address is connected to an authentic IP address, the attacker will begin receiving any data that is intended for that IP address. ARP spoofing can enable malicious parties to intercept, modify or even stop data in-transit. ARP spoofing attacks can only occur on local area networks that utilize the Address Resolution Protocol.

As it's said in the previous definition, this attack is totally malicious but only on a local area. Do not attend this kind of attack without clear authorization. If you're getting caught using this on your job's network or a private network, you can have serious trouble.

With that said, I cannot be made responsible if you have any problems after using this tool. So use it with cautions or (this is better) with authorization from the owner's scanned device.

This script works only on Linux. But if you IP forward your Windows, and bypass enable_linux_iproute() methods, then it should work on your Windows computer

You need to have Scapy installed on your computer as well as requests, pyfiglet and termcolor

You need to be root or at least you need to have right to perform sudo command

You need to launch this script only once as it's sending forged packets to target and to impersonated host.

You can have further instructions on how to make script works with the following command

python3 arp_spoofer.py -h
