Being able to infiltrate communications between devices is extremely valuable to a hacker. On this episode of Cyber Weapons Lab, we’ll show you how to create and manipulate packets with a Python tool called Scapy.

This is just a quick example of how a hacker could use Scapy to craft packets that allow them to stay under the radar even when they’re doing things on a network that they’re connected to. Because Scapy allows us to build packets from scratch, it means we can get as creative as we want. If we want to kick someone off the network while not being so obvious it was us, we can simply create fake packets that say that the router is the one kicking them off. We can also run a network scan by simply pretending to be the router sending out ARP requests getting everybody to reply and just sitting back and listening for those replies with Wireshark. It’s really easy to use Scapy for a variety of different creative things, and the more you learn about TCP/IP, the more useful it will be for your hacking endeavors.
