DNS spoofing is the manipulation of the DNS resolver cache by inputting corrupted DNS data. This causes the DNS server to send the user the wrong IP, redirecting the victim to the attacker's fake domain. When launching evil twin attacks, attackers will often use DNS spoofing to redirect the victim to a cloned landing page or website. This leads to setting up the victim for a MITM attack. DNS cache poisoning is a popular method hackers use to spoof DNS quickly and efficiently. Most users on the same wireless network will usually share the same DNS cache provided by the ISP DNS server. When users are logged on the evil twin, a hacker can easily inject a spoofed DNS record into the DNS cache changing the DNS record for all users on the fake network. When any user logs into the evil twin they will be redirected by the spoofed DNS record injected into the cache. Remember, the DNS cache is what...

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.
