FOR585: Advanced Smartphone Forensics
It is almost impossible today to conduct a digital forensic investigation that does not include a smartphone or mobile device. Smartphones are replacing the need for a personal computer, and almost everyone owns at least one. The smartphone may be the only source of digital evidence tracing an individual's movements and motives, and thus can provide the who, what, when, where, why, and how behind a case. FOR585: Advanced Smartphone Forensics teaches real-life, hands-on skills that help digital forensic examiners, law enforcement officers, and information security professionals handle investigations involving even the most complex smartphones currently available.
The course focuses on smartphones as sources of evidence, providing students with the skills needed to handle mobile devices in a forensically sound manner, manipulate locked devices, understand the different technologies, discover malware, and analyze the results for use in digital investigations by diving deeper into the file systems of each smartphone. Students will be able to obtain actionable intelligence and recover and analyze data that commercial tools often miss for use in internal investigations, criminal and civil litigation, and security breach cases. Students will walk away with knowledge they can immediately put to use on their next smartphone investigation.
FOR585: Advanced Smartphone Forensics you will learn:
- Smartphone Capabilities: Determine the who, what, when, where, why, and how of a case. Who used a smartphone? What did the user do on a smartphone? Where was the smartphone located at key times? What online activities did the user conduct using a smartphone, and when?
- How to Recover Deleted Data: Use manual decoding techniques to recover deleted data stored on smartphones and mobile devices.
- How to Detect Data Stored in Third-Party Applications: Who did the user communicate with using a smartphone and why are these activities sometimes hidden?
- How to Detect Malware: Detect smartphones compromised by malware using forensics methods.
- How to Bypass Locks: Bypass, crack, and/or decode lock codes manually recovered from smartphones, including cracking iOS backup files that were encrypted with iTunes.
The hands-on exercises in this course cover the best commercial and open-source tools available to conduct smartphone and mobile device forensics, and provide detailed instructions on how to manually decode data that tools sometimes overlook. The course will prepare you to recover and reconstruct events relating to illegal or unauthorized activities, determine if a smartphone has been compromised with malware or spyware, and provide your organization with the capability to use evidence from smartphones.
This intensive six-day course will take your mobile device forensics knowledge and abilities to the next level. Smartphone technologies are new and constantly changing, most forensics professionals are unfamiliar with the data formats. It is time for the good guys to get smarter and for the bad guys to know that their texts and apps can and will be used against them!

|FOR585.1: Smartphone Overview and Malware Forensics|
Focus: Although smartphone forensics concepts are similar to those of digital forensics, smartphone file system structures differ and require specialized decoding skills to correctly interpret the data acquired from the device. On this first course day, students will apply what they know to smartphone forensics handling, device capabilities, acquisition methods, and data encoding concepts of smartphone components. Students will also become familiar with the forensics tools required to complete comprehensive examinations of smartphone data structures. Malware affects a plethora of smartphone devices. This section will examine various types of malware, how it exists on smartphones, and how to identify it. Up to five labs will be conducted on this first day alone!
All examiners today have to address the existence of malware on smartphones. Often the only questions relating to an investigation may be whether a given smartphone was compromised, how, and what can be done to fix it. It is important for examiners to understand malware and how to identify its existence on the smartphone.
Smartphones will be introduced and defined to set our expectations for what we can recover using digital forensics methodologies. We review the properties of Flash memory in mobile devices and demonstrate the pros and cons from a forensics perspective. We provide approaches for dealing with common challenges such as encryption, passwords, and damaged devices. Students will learn how to process and decode data on mobile devices from a forensics perspective, then learn tactics to recover information that even forensics tools may not always be able to retrieve.
