Imagine an attack surface spread throughout your organization, in the hands of every user, which moves from place to place regularly, stores highly sensitive and critical data, and sports numerous different wireless technologies all ripe for attack. You have it today: mobile devices. These devices are the biggest attack surface in most organizations today, yet these same organizations often don't have the skills needed to assess them.


Mobile devices are no longer a convenience technology: they are an essential tool carried or worn by users worldwide, often displacing conventional computers for everyday enterprise data needs. You can see this trend in corporations, hospitals, banks, schools, and retail stores throughout the world. Users rely on mobile devices more today than ever before - we know it, and the bad guys do too.


This course is designed to give you the skills you need to understand the security strengths and weaknesses in Apple iOS, Android, and wearable devices including Apple Watch and Android Wear. With these skills, you will evaluate the security weaknesses of built-in and third party applications. You'll learn how to bypass platform encryption, and how to manipulate Android apps to circumvent obfuscation techniques. You'll leverage automated and manual mobile application analysis tools to identify deficiencies in mobile app network traffic, file system storage, and inter-app communication channels. You'll safely work with mobile malware samples to understand the data exposure and access threats affecting Android and iOS devices, and you'll exploit lost or stolen devices to harvest sensitive mobile application data.



Understanding and identifying vulnerabilities and threats to mobile devices is a valuable skill, but it must be paired with the ability to communicate the associated risks. Throughout the course, you'll review the ways in which we can effectively communicate threats to key stakeholders. You'll leverage tools including Mobile App Report Cards to characterize threats for management and decision makers, while identifying sample code and libraries that developers can use to address risks for in-house applications as well.


Through the use of your new skills, you'll apply a mobile device deployment penetration test in a step-by-step fashion. Starting with gaining access to wireless networks to implement man-in-the-middle attacks and finishing with mobile device exploits and data harvesting, you'll examine each step in conducting such a test with hands-on exercises, detailed instructions, and tips and tricks learned from hundreds of successful penetration tests. By building these skills, you'll return to work prepared to conduct your own test, or better informed on what to look for and how to review an outsourced penetration test.

Mobile device deployments introduce new threats to organizations including advanced malware, data leakage, and the disclosure of enterprise secrets, intellectual property, and personally identifiable information assets to attackers. Further complicating matters, there simply are not enough people with the security skills needed to identify and manage secure mobile phone and tablet deployments. By completing this course, you'll be able to differentiate yourself as having prepared to evaluate the security of mobile devices, to effectively assess and identify flaws in mobile applications, and to conduct a mobile device penetration test - all critical skills to protect and defend mobile device deployments.

The first section of the course quickly looks at the significant threats affecting mobile device deployments, highlighted with 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 in Android (including Android Marshmallow), Apple iOS 10, and the Apple Watch and Google Wear platforms. 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.

We'll look at the tools used to evaluate mobile devices as part of establishing a lab environment for mobile device assessments including the analysis of mobile malware affecting Android and non-jailbroken iOS devices. Finally, we will address the threats of lost and stolen devices (and opportunities for a pen tester) including techniques to bypass mobile device lock screens.

An essential component of developing a secure mobile device deployment is to perform or outsource a penetration test. Through ethical hacking and penetration testing, we examine the mobile devices and infrastructure from the perspective of an attacker, identifying and exploiting flaws that deliver unauthorized access to data or supporting networks. 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 pen test, or to source and evaluate the pen tests of others, understanding these techniques will help your organization identify and resolve vulnerabilities before they become incidents.

"SEC575 provides a pretty comprehensive overview of different attack vectors and vulnerabilities in the mobile field. It covers many topics in enough depth to really get a foothold in the subject. I wish I had taken this course several years ago when first entering the mobile landscape. It would have saved me months of painful self-teaching, and is vastly more complete in many areas." - Jeremy Erickson, Sandia National Labs

SEC575 Mobile Device Security and Ethical Hacking Review by Matt Edmonson

Author Statement

I'm not sure exactly when it happened, but laptops and PCs have become legacy computing devices, replaced by mobile phones and tablets. Just when I thought we were getting a much better handle on the security of Windows, Mac, and other Unix systems, there has been an explosion of new devices wanting to join our networks that simply do not have the same security controls that we rely on in modern, secure networks.

Even with their weaknesses, mobile phones are here to stay, and we are being called on to support them more and more. Some organizations try to drag their feet on allowing mobile phones, but that ultimately contributes to the problem: if we do not address security, the threats continue to grow, uncontrolled and unmonitored.

Fortunately, we can securely deploy, manage and monitor mobile phones and tablets inside our organizations through policy and careful network deployment and monitoring. We need to build some essential skills in analyzing the risks of data leakage in mobile code and in the applications our end-users want to run from the app store. And we need to ethically hack our networks to identify the real threat and exposure of mobile phone weaknesses.

I wrote this course to help people build their skills in all these areas, focusing on the topics and concepts that are most important and immediately useful. Every organization should have an analyst who has the skills for mobile phone security analysis and deployment. By taking this course, you will become an even more valued part of your organization. And we'll have lots of geeky fun in getting you there!
