Applied Network Security

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.

Veil-Evasion

The first tool we will use is called Veil-Evasion. What is Veil-Evasion and how does it work? Most devices that have some kind of antivirus software will be able to detect basic Meterpreter binaries. These binaries are found within the payload. If you remember our lab in Chapter 4, Creating a RAT Using Msfvenom, we created a RAT using msfvenom and Meterpreter. When we created that RAT we used a popular Metasploit encoder named Shikata_ga_nai. This encoder was used to bypass antivirus protection in the Windows OS. Due to Shikata's popularity, most AVs solutions have recorded Shikata's signature in their databases. This results in Shikata being detected and stopped immediately by most AVs. A hacker may use Veil-Evasion to get around this.

Veil-Evasion uses a number of different encoding methods to change file signatures to avoid detection. When Veil-Evasion manipulates the file signature, AV...
