SEC573: Python for Penetration Testers
SEC573 gave me exposure to tools and techniques I wouldn't have normally considered, but now are part of my arsenal.
So far the content of Python for Penetration Testers has been great. I have learned several things, even as an advanced user.
Python for penetration testers at Hackfest 2014. Your target has been well hardened. So far, your every attempt to compromise their network has failed. But, you did find evidence of a vulnerability, a lucky break in their defensive posture. Sadly, all of your tools have failed to successfully exploit it. Your employers demand results. What do you do when off-the-shelf tools fall short? You write your own tool.
The best penetration testers can customize existing open source tools or develop their own tools. The ability to read, write, and customize software is what distinguishes the good penetration tester from the great penetration tester. This course, SEC573: Python for Penetration Testers at Hackfest, is designed to give you the skills you need for tweaking, customizing, or outright developing your own tools to put you on the path of becoming a great penetration tester. Again and again, organizations serious about security emphasize their need for skilled tool builders. There is a huge demand for people who can understand a problem and then rapidly develop prototype code to attack or defend against it. Join us and learn Python in-depth and fully weaponized.
Unfortunately, many penetration testers at Hackfest do not have these skills today. The time and effort required to develop programming skills may seem overwhelming. But it is not beyond your reach. This course is designed to meet you at your current skill level, appealing to a wide variety of backgrounds ranging from people without a drop of coding experience all the way up to skilled Python developers looking to increase their expertise and map their capabilities to penetration testing. Because you can't become a world-class tool builder by merely listening to lectures, the course is chock full of hours of hands-on labs every day that will teach you the skills required to develop serious Python programs and how to apply those skills in penetration testing engagements.
SEC573: Python for Penetration Testers at Hackfest begins with an introduction to SANS pyWars. pyWars is a 4-day Capture the Flag competition that runs parallel to the course material. It will challenge your existing programming skills and help you develop new skills at your own individualized pace. This allows experienced programmers to quickly progress to more advanced concepts while novice programmers spend time building a strong foundation. This individualized approach allows everyone to hone their current skills making them the most lethal weapon they can be.
After introducing pyWars, here at Hackfest, the course will cover the essentials skills required to get the most out of the Python language. The essentials workshop labs will teach the concepts and techniques required to develop your own tools to those that are new to software development. The essentials workshop will also teach shortcuts that will make experienced developers even more deadly. Then we turn to applying those skills in today's real work penetration testing scenarios. You will develop a port scanning, antivirus evading, client infecting backdoor for placement on target systems. You will develop a SQL injection tool to extract data from websites that fail with off the shelf tools. You will develop a multi-threaded password guessing tool and a packet assembling network reconnaissance tool. The course concludes with a one-day Capture the Flag event that will test both your ability to apply your new tools and coding skills in a penetration testing challenge.
By the end of this course, students will have learned essentials skills that every penetration tester should have. For your next engagement you will command and conquer as you:
- Write a backdoor that uses Exception Handling, Sockets, Process execution, and encryption to provide you with your initial foothold in a target environment. The backdoor will include features such as a port scanner to find an open outbound port, the ability to evade antivirus software and network monitoring and the ability to embed payload from tools such as Metasploit.
- Write a SQL Injection tool that uses standard Python libraries to interact with target websites. You will be able to use different SQL attack techniques for extracting data from a vulnerable target system.
- Develop a password guessing attack tool with features like multi-threading, cookie handlers, support for application proxies such as Burp and much much more.
- Write a network reconnaissance tool that uses SCAPY, cStringsIO and PIL to reassemble TCP packet streams, extract data payloads such as images, display images, extract Metadata such as GPS coordinates and link those images with GPS coordinates to Google maps.

Participants will exercise the skills and code they have developed over the previous four days as they exploit vulnerable systems, break encryption cyphers, and remotely execute code on target systems. Test your skills! Prove your might!
CPE/CMU Credits: 6
To get the most value out of the course, students are required to bring their own laptop so that they can connect directly to the workshop network that we will create. It is the students' responsibility to make sure that the system is properly configured with all drivers necessary to connect to an Ethernet network.
Some of the course exercises are based on Windows, while others focus on Linux. VMware Player or VMware Workstation is required for the class. If you plan to use a Macintosh, please make sure you bring VMware Fusion, along with a Windows guest virtual machine.
You are required to bring Windows 7 (Professional, Enterprise, or Ultimate), Windows Vista (Business, Enterprise, or Ultimate), either a real system or a virtual machine. Windows 8 Pro is an acceptable option.
You will require administrative access to your Windows computer and the ability to install various software packages including Python on that computer.
IMPORTANT NOTE: You may also be required to disable your anti-virus tools temporarily for some exercises, so make sure you have the anti-virus administrator permissions to do so. DO NOT plan on just killing your anti-virus service or processes because most anti-virus tools still function even when their associated services and processes have been terminated. For many enterprise-managed clients, disabling your anti-virus tool may require a different password than the Administrator account password. Please bring that administrator password for your anti-virus tool.
The course includes a VMware image file of a guest Linux system that is larger than 5 GB. Therefore, you need a file system with the ability to read and write files that are larger than 5 GB, such as NTFS on a Windows machine.
Enterprise VPN clients may interfere with the network configuration required to participate in the class. If your system has an enterprise VPN client installed, you may need to uninstall it for the exercises in class.
You will use VMware to run Windows and Linux operating systems simultaneously when performing exercises in class. You must have either the free VMware Player 3 or later or the commercial VMware Workstation 6 or later installed on your system prior to coming to class. You can download VMware Player for free here.
Alternatively, if you want a more flexible and configurable tool, you can download a free 30-day trial copy of VMware Workstation here. VMware will send you a time- limited license number for VMware Workstation if you register for the trial at their Web site. No license number is required for VMware Player.
We will give you a DVD full of tools to use during the class and take home for later analysis. We will also provide a Linux image with all of our tools pre-installed that runs within VMware Player or VMware Workstation.
You do not need to bring a Linux system if you plan to use our Linux image in VMware. However, you are required to bring VMware Workstation or VMware Player. The class does not support VirtualPC or other non-VMware virtualization products.
Mandatory Laptop Hardware Requirements
- x86- or x64-compatible 1.5 GHz CPU Minimum or higher
- DVD Drive (not a CD drive)
- 2 GigaByte RAM minimum with 4 GB or higher recommended
- Ethernet adapter (A wired connection is required in class. If your laptop supports only wireless, please make sure to bring an Ethernet adapter with you.)

Today basic scripting skills are essential to professionals in all aspects of information security. Understanding how to develop your own applications means you can automate tasks and do more, with fewer resources, in less time. As penetration testers, knowing how to use canned information security tools is a basic skill that you must have. Knowing how to build your own tools when the tools someone else wrote fail is what seperates the great penetration testers from the good. This course is designed for security professionals who have some basic scripting skills and want to learn how to apply them to the field of penetration testing. The course will cover the essential skills that are needed to develop applications that interact with networks, websites, databases, and file systems so you can take your career to the next level. We will cover these essential skills as we build practical applications that you can immediately put into use in your penetration tests. -Mark Baggett
