Overview of this book

In this age, where online information is at its most vulnerable, knowing how to execute the same attacks that hackers use to break into your system or network helps you plug the loopholes before it's too late and can save you countless hours and money. Kali Linux is a Linux distribution designed for penetration testing and security auditing. It is the successor to BackTrack, the world's most popular penetration testing distribution. Discover a variety of popular tools of penetration testing, such as information gathering, vulnerability identification, exploitation, privilege escalation, and covering your tracks. Packed with practical recipes, this useful guide begins by covering the installation of Kali Linux and setting up a virtual environment to perform your tests. You will then learn how to eavesdrop and intercept traffic on wireless networks, bypass intrusion detection systems, and attack web applications, as well as checking for open ports, performing data forensics, and much more. The book follows the logical approach of a penetration test from start to finish with many screenshots and illustrations that help to explain each tool in detail. The Kali Linux Cookbook will serve as an excellent source of information for the security professional and novice alike!

Physical access attacks


In this recipe, we will utilize SUCrack to perform a physical access password attack. SUCrack is a multithreaded tool that allows for brute-force cracking of local user accounts via su. The su command in Linux allows you to run commands as a substitute user. This attack, though useful when you are unable to escalate privileges on a Linux/Unix system by other means, will fill up the log files rather quickly so please be sure to clean the log files after completion.

SUCrack has several command options that we can use:

  • --help allows you to view the help file for SUCrack.

  • -l allows you to change the user whose login we are attempting to circumvent.

  • -s allows you to set the number of seconds between when statistics are displayed. The default setting is every 3 seconds.

  • -a allows you to set whether ANSI escape codes should be used or not.

  • -w allows you to set the number of worker threads that SUCrack can utilize. Since SUCrack is multi threaded, you can run as many worker...
