What You Will Learn
Imagine an attack surface that is spread across your organization and in the hands of every user. It moves regularly from place to place, stores highly sensitive and critical data, and sports numerous and different wireless technologies all ripe for attack. Unfortunately, such a surface already exists today: mobile devices. These devices constitute the biggest attack surface in most organizations, yet these same organizations often don't have the skills needed to assess them.

The first section of SEC575 looks at the significant threats affecting mobile device deployments, highlighted by a hands-on exercise evaluating network traffic from a vulnerable mobile banking application. As a critical component of a secure deployment, we will examine the architectural and implementation differences and similarities between Android (including Android 10) and Apple iOS 13. We will also look at the specific implementation details of popular platform features such as iBeacon, AirDrop, App Verification, and more. Hands-on exercises will be used to interact with mobile devices running in a virtualized environment, including low-level access to installed application services and application data. Finally, we will examine how applications interact with each other, as application interaction creates an interesting attack surface for mobile penetration tests.

A very important threat for mobile devices is the stolen or lost device, as this can cause a major disclosure of sensitive information. In this course section we first examine how a device can be properly protected, and how someone might be able to circumvent those protections. Once access to the device has been obtained, we examine which information is available and how we can access it. On the other hand, gaining privileged access to a device is often needed to perform a security assessment, so we will take a look at the steps required to root an Android phone and jailbreak an iOS device. At the end of the section, we will take a look at how mobile malware (ab)uses the ecosystem to steal money or data or brick the device.

One of the core skills you need as a mobile security analyst is the ability to evaluate the risks and threats a mobile app introduces to your organization. The lectures and hands-on exercises presented in this course section will enable you to use your analysis skills to evaluate critical mobile applications to determine the type of access threats and information disclosure threats they represent. We will use automated and manual application assessment tools to statically evaluate iOS and Android apps. Initially, the applications will be easy to understand, but towards the end of the section we will dig into obfuscated applications that are far more difficult to dissect. Finally, we will examine different kinds of application frameworks and how they can be analyzed with specialized tools.
Reverse-Engineering Obfuscated Applications

After having performed static analysis on applications in section 3, we now move on to dynamic analysis. A skilled analyst combines both static and dynamic analysis to evaluate the security posture of an application. Using dynamic instrumentation frameworks, we see how applications can be modified at runtime, how method calls can be intercepted and modified, and how we can have direct access to the native memory of the device. We will learn about Frida, Objection, Needle, Drozer, and method swizzling to fully instrument and examine both Android and iOS applications. The section ends with a look at a consistent system for evaluating and grading the security of mobile applications using the Application Report Card Project. By identifying these flaws we can evaluate the mobile phone deployment risk to the organization with practical and useful risk metrics. Whether your role is to implement the penetration test or to source and evaluate the penetration tests of others, understanding these techniques will help you and your organization identify and resolve vulnerabilities before they become incidents.

After having analyzed the applications both statically and dynamically, one component is still left untouched: the back-end server. In this course section we will examine how you can perform ARP spoofing attacks on a network in order to obtain a man-in-the-middle position, and how Android and iOS try to protect users from having their sensitive information intercepted. Next, we'll examine how you can set up a test device to purposely intercept the traffic in order to find vulnerabilities on the back-end server. We end the section by creating a RAT application that can be used during a red team assessment in order to target users and gain access to internal networks.

Important! Bring your own system configured according to these instructions!
We ask that you do 5 things to prepare prior to class start. This early preparation will allow you to get the most out of your training. One of those five steps is ensuring that you bring a properly configured system to class. This document details the required system hardware and software configuration for your class. You can also watch a series of short videos on these topics at the following web link https://sansurl.com/sans-setup-videos.
A properly configured system is required to fully participate in this course. If you do not carefully read and follow these instructions, you will likely leave the class unsatisfied because you will not be able to participate in hands-on exercises that are essential to this course. Therefore, we strongly urge you to arrive with a system meeting all the requirements specified for the course.
In this course, students will use an advanced lab system to maximize the time spent on learning objectives and minimize setup and troubleshooting.
Students may use the latest version of Windows 10 or macOS 10.15.x or later for exercises. You will need a wired network adapter to connect to the classroom network. Larger laptop displays will make for an improved lab experience (less scrolling).
Your course media will now be delivered via download. The media files for class can be large, some in the 40 - 50 GB range. You need to allow plenty of time for the download to complete. Internet connections and speed vary greatly and are dependent on many different factors. Therefore, it is not possible to give an estimate of the length of time it will take to download your materials. Please start your course media downloads as you get the link. You will need your course media immediately on the first day of class. Waiting until the night before the class starts to begin your download has a high probability of failure.
SANS has begun providing printed materials in PDF form. Additionally, certain classes are using an electronic workbook in addition to the PDFs. The number of classes using eWorkbooks will grow quickly. In this new environment, we have found that a second monitor and/or a tablet device can be useful by keeping the class materials visible while the instructor is presenting or while you are working on lab exercises.
"The first iPhone was released in 2007, and it is considered by many to be the starting point of the smartphone era. Over the past decade, we have seen smartphones grow from rather simplistic into incredibly powerful devices with advanced features such as biometrics, facial recognition, GPS, hardware-backed encryption and beautiful high-definition screens. While many different smartphone platforms have been developed over the years, it's quite obvious that Android and iOS have come out victorious.
"While smartphones provide a solid experience right out of the box, the app ecosystem is probably the most powerful aspect of any mobile OS. Both the Google Play and Apple App stores have many millions of applications that increase the usefulness of their platforms and include everything from games to financial applications, navigation, movies, music, and countless other offerings.
"However, many people's smartphones also contain an incredible amount of data about both their personal and professional lives. Keeping those data secure should be a primary concern for both the OS and the mobile application developer. Yet, many companies today have implemented a bring-your-own-device policy that allows smartphones onto their network. These devices are often not managed and thus bring a new set of security threats to the company.
"I wrote this course to teach you about all the different aspects of mobile security, both at a high level and down into the nitty-gritty details. You will learn how to analyze mobile applications, attack smartphone devices on the network, man-in-the-middle either yourself or others, and root/jailbreak your device. You'll also learn what kind of malware may pose a threat to your company and your employees.
"Mobile security is a lot of fun, and I hope you will join this course so that we can share our enthusiasm with you!"
