What is Scapy? Tool for reading and writing packets – Sniff on the wire, decode, rewrite, create from scratch, and more! Written by Philippe Biondi – Can be used from standalone console or from within your own Python scripts – Python 2.4 or greater Intro to Crafting Packets with Scapy – Anthony Critelli

What can you use it for? Intro to Crafting Packets with Scapy – Anthony Critelli

Test your network applications! Intro to Crafting Packets with Scapy – Anthony Critelli

Replace other tools! Intro to Crafting Packets with Scapy – Anthony Critelli

Build your own tools! Intro to Crafting Packets with Scapy – Anthony Critelli

Some important Scapy commands ls() – show available scapy protocols lsc() – show available scapy functions show() – display packet field information and values send() – send packets at Layer 3 sendp() – send packets at Layer 2 sr() – send packets and receive response sr1() – send packets and receive only 1 response Intro to Crafting Packets with Scapy – Anthony Critelli
