Can Your Web Apps Withstand the Onslaught of Modern Advanced Attack Techniques?
Modern web applications are growing more sophisticated and complex as they utilize exciting new technologies and support ever-more critical operations. Long gone are the days of basic HTML requests and responses. Even in the age of Web 2.0 and AJAX, the complexity of HTTP and modern web applications is progressing at breathtaking speed. With the demands of highly available web clusters and cloud deployments, web applications are looking to deliver more functionality in smaller packets at a decreased strain on backend infrastructure. Welcome to an era that includes tricked-out cryptography, WebSockets, HTTP/2, and a whole lot more. Are your web application assessment and penetration testing skills ready to evaluate these impressive new technologies and make them more secure?
Are You Ready To Put Your Web Apps To the Test with Cutting-Edge Skills?
This pen testing course is designed to teach you the advanced skills and techniques required to test modern web applications and next-generation technologies. The course uses a combination of lecture, real-world experiences, and hands-on exercises to teach you the techniques to test the security of tried-and-true internal enterprise web technologies, as well as cutting-edge Internet-facing applications. The final course day culminates in a Capture the Flag competition where you will apply the knowledge you acquired during the previous five days in a fun environment based on real-world technologies.
Hands-on Learning Of Advanced Web App Exploitation Skills
We begin by exploring advanced techniques and attacks to which all modern-day complex applications may be vulnerable. We'll learn about new web frameworks and web backends, then explore encryption as it relates to web applications, digging deep into practical cryptography used by the web, including techniques to identify the type of encryption in use within the application and methods for exploiting or abusing it. We'll look at alternative front ends to web applications and web services such as mobile applications, and examine new protocols such as HTTP/2 and WebSockets. The final portion of class will focus on how to identify and bypass web application firewalls, filtering, and other protection techniques.
You Will Learn:
- How to discover and exploit vulnerabilities in modern web frameworks, technologies, and backends
- Skills to test and exploit specific technologies such as HTTP/2, Web Sockets, and Node.js
- How to evaluate and find vulnerabilities in the many uses of encryption within modern web applications
- Skills to test and evaluate mobile backends and web services used in an enterprise
- Methods to recognize and bypass custom developer, web framework, and Web Application Firewall defenses
SEC642.1: Advanced Attacks
As applications and their vulnerabilities become more complex, penetration testers have to be able to handle advanced targets. We'll start the course with a warm-up pen test of a small application. After our review of this exercise, we will explore some of the more advanced techniques for LFI/RFI and SQLi server-based flaws. We will then take a stab at combined XSS and XSRF attacks, where we leverage the two vulnerabilities together for even greater effect. After discovering the flaws, we will then work through various ways to exploit these flaws beyond the typical means exhibited today. These advanced techniques will help penetration testers find ways to demonstrate these vulnerabilities to their organization through advanced and custom exploitation.

SEC642.3: Web Application Encryption
Cryptographic weaknesses are a major area of web application vulnerabilities, yet very few penetration testers have the skill to investigate, attack, and exploit these flaws. When we investigate web application crypto attacks, we typically target the implementation and use of cryptography in modern web applications. Many popular web programming languages or development frameworks make encryption services available to the developer. Often they do not protect encrypted data from being attacked, or they permit the developer to use cryptography in a weak manner. These implementation mistakes are going to be our focus in this section, as opposed to the exploitation of deficiencies in the cryptographic algorithms themselves. We will also explore the various ways applications use encryption and hashing insecurely. Students will learn techniques ranging from identifying types of encryption to exploiting various flaws within encryption or hashing techniques.
- Analyzing Crypto
- Working through obscurity with data encoding
- Exploiting weak keys chosen by the backend system
- Attacking stream ciphers
- Discovering and exploiting ECB Shuffling in web applications

- Exploiting Cipher Block Chaining (CBC) Mode with bit flipping
- Vulnerabilities in PKCS#7 padding implementations
SEC642.4: Alternate Web Interfaces
Web applications are no longer limited to the traditional HTML-based interfaces. Web services and mobile applications have become more common and are regularly being used to attack clients and organizations. As such, it has become very important that penetration testers understand how to evaluate the security of these systems. We will examine Flash, Java, Active X, and Silverlight flaws. We will explore various techniques to discover flaws within the applications and backend systems. These techniques will make use of tools such as Burp Suite and other automated toolsets. We'll use lab exercises to explore the newer protocols of HTTP/2 and WebSockets, exploiting flaws exposed within each of them.
- Wireshark stream extraction to custom pentester requests
- Decompiling Flash objects
- Exploiting a SOAP-based web service
- Playing with WebSockets in SocketToMe

SEC642.5: Web Application Firewall and Filter Bypass
Applications today are using more security controls to help prevent attacks. These controls, such as Web Application Firewalls and filtering techniques, make it more difficult for penetration testers during their testing. The controls block many of the automated tools and simple techniques used to discover flaws. On this day we'll explore techniques used to map the control and how that control is configured to block attacks. You'll be able to map out the rule sets and determine the specifics of how the Web Application Firewall detects attacks. This mapping will then be used to determine attacks that will bypass the control. You'll use HTML5, UNICODE, and other encodings that will enable your discovery techniques to work within the protected application.

SEC642.6: Capture the Flag
On this final course day you will be placed on a network and given the opportunity to complete an entire penetration test. The goal of this exercise is for you to explore the techniques, tools, and methodology you will have learned over the last five days. You'll be able to use these skills against a realistic extranet and intranet. At the end of the day, you will provide a verbal report of the findings and methodology you followed to complete the test. Students will be provided with a virtual machine that contains the Samurai Web Testing Framework (SamuraiWTF). You will be able to use this both in the class and after leaving and returning to your jobs.
CPE/CMU Credits: 6
- x64-compatible 2.0 GHz CPU minimum or higher
- At least 20 GB of hard drive space
- At least 4 GB of RAM, preferably 8 GB of RAM
- An Ethernet port or Ethernet adapter to plug into a private, in-class network.
VMware: One of the following versions of VMware or newer pre-installed before class begins: VMware Workstation Player 12, VMware Workstation Pro 12, VMware Fusion 8, or VMware Fusion Pro 8. You can download a free 30-day trial of any of these here. Other virtualization software such as Parallels or VirtualBox may work if attendees are capable of supporting it themselves. However, VMware should be installed as a backup just in case
IMPORTANT NOTE: While not usually necessary for this class, you may 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.
During the hands-on exercises, you will be connecting to the classroom network. While contrary to exercise rules and SANS ethics policy, your laptop might be attacked. Do not have any sensitive data stored on the system. SANS is not responsible for your system if someone in the class attacks it in the workshop.
By bringing the right equipment and preparing in advance, you can maximize what you will see and learn, as well as have a lot of fun.
If you have additional questions about the laptop specifications, please contact email@example.com.
