Scapy is a packet manipulation tool. You can thus create custom packets to deliver your payload (data) to a victim PC or network. This too was written by Philippe Biondi in the computer language python, for packet decoding, construction, and manipulation. The practical applications are vast and powerful, from packet decoding, construction, and manipulation to malicious implementations such as DDoS to MITM attacks and even manually injecting backdoors. You can create and send packets, or filter to receive specific packets on the network. You can also scan a pcap file or write packets into the pcap and even layer packets. You can also use it for testing a variety of possible attack vectors or troubleshoot network issues. As you can see, this packet generator has a lot of potential and capability for both sides so I hope you pay close attention in this chapter. Before we get started however make sure you have...

Overview of this book
Computer networks are increasing at an exponential rate and the most challenging factor organisations are currently facing is network security. Breaching a network is not considered an ingenious effort anymore, so it is very important to gain expertise in securing your network. The book begins by showing you how to identify malicious network behaviour and improve your wireless security. We will teach you what network sniffing is, the various tools associated with it, and how to scan for vulnerable wireless networks. Then we’ll show you how attackers hide the payloads and bypass the victim’s antivirus. Furthermore, we’ll teach you how to spoof IP / MAC address and perform an SQL injection attack and prevent it on your website. We will create an evil twin and demonstrate how to intercept network traffic. Later, you will get familiar with Shodan and Intrusion Detection and will explore the features and tools associated with it. Toward the end, we cover tools such as Yardstick, Ubertooth, Wifi Pineapple, and Alfa used for wireless penetration testing and auditing. This book will show the tools and platform to ethically hack your own network whether it is for your business or for your personal home Wi-Fi.
