Networks around the world are continually plagued by DDoS attacks. These types of attacks can be devastating to a business, costing them millions of dollars in some cases. Botnets are often used by hackers to launch DDoS attacks. Remember, botnets are compromised devices remotely controlled by a hacker through a C&C server. Think of a bot as a zombie machine. A group of bots or zombies is called a botnet. Until recently, botnets have usually been compromised of desktop or laptop devices taken over on large enterprise networks. The larger the botnet, the more effective it is in launching DDoS attacks. The IoT has changed how botnets are built. Any device/object embedded with IoT can become a bot. For example, CCTV cameras have been a favorite target for hackers creating botnets. Each camera acts as an individual node, sending data to a central node (usually a cloud server) over the internet.

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.
