SMARTPHONES HAVE MINDS OF THEIR OWN.
DON'T MAKE THE MISTAKE OF REPORTING SYSTEM EVIDENCE, SUGGESTION, OR APPLICATION ASSOCIATIONS AS USER ACTIVITY.
IT'S TIME TO GET SMARTER!
A smartphone lands on your desk and you are tasked with determining if the user was at a specific location at a specific date and time. You rely on your forensic tools to dump and parse the data. The tools show location information tying the device to the place of interest. Are you ready to prove the user was at that location? Do you know how to take this further to place the subject at the location of interest at that specific date and time? Tread carefully, because the user may not have done what the tools are showing!
Mobile devices are often a key factor in criminal cases, intrusions, IP theft, security threats, accident reconstruction, and more. Understanding how to leverage the data from the device in a correct manner can make or break your case and your future as an expert. FOR585: Smartphone Forensic Analysis In-Depth will teach you those skills.
Every time the smartphone "thinks" or makes a suggestion, the data is saved. It's easy to get mixed up in what the forensic tools are reporting. Smartphone forensics is more than pressing the "find evidence" button and getting answers. Your team cannot afford to rely solely on the tools in your lab. You have to understand how to use them correctly to guide your investigation, instead of just letting the tool report what it believes happened on the device. It is impossible for commercial tools to parse everything from smartphones and understand how the data was put on the device. Examination and interpretation of the data is your job and this course will provide you and your organization with the capability to find and extract the correct evidence from smartphones with confidence.
This in-depth smartphone forensic course provides examiners and investigators with advanced skills to detect, decode, decrypt, and correctly interpret evidence recovered from mobile devices. The course features 31 hands-on labs, a forensic challenge, and a bonus take-home case that allow students to analyze different datasets from smart devices and leverage the best forensic tools, methods, and custom scripts to learn how smartphone data hide and can be easily misinterpreted by forensic tools. Each lab is designed to teach you a lesson that can be applied to other smartphones. You will gain experience with the different data formats on multiple platforms and learn how the data are stored and encoded on each type of smart device. The labs will open your eyes to what you are missing by relying 100% on your forensic tools.
FOR585 is continuously updated to keep up with the latest malware, smartphone operating systems, third-party applications, acquisition short-falls, and encryption. This intensive six-day course offers the most unique and current instruction on the planet, and it will arm you with mobile device forensic knowledge you can immediately apply to cases you're working on the day you leave the course.
Smartphone technologies are constantly changing, and most forensic professionals are unfamiliar with the data formats for each technology. Take your skills to the next level: it's time for the good guys to get smarter and for the bad guys to know that their smartphone activity can and will be used against them!

Course Syllabus
FOR585.1: Smartphone Overview, Misfit Devices, SQLite Introduction, and Android Forensics Overview
Overview
Focus: Although smartphone forensic 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 forensic handling, device capabilities, acquisition methods, misfit devices, SQLite database examination, and query development. They'll also gain an overview of Android devices and manually crack locked Androids.
Students will become familiar with the forensic tools required to complete comprehensive examinations of smartphone data structures. We realize that not everyone examines BlackBerry and knock-off devices, which is why we offer "choose your own adventure" labs, meaning that students can select the labs most relevant to them. BlackBerry 10 smartphones are designed to protect user privacy, but techniques taught on this course day will enable the investigator to go beyond what the tools decode and manually recover data residing in database files of BlackBerry 10 device file systems. Knock-off devices are another outlier than can be parsed and decoded once you become familiar with the file system structures.
Smartphones will be introduced and defined to set our expectations for what we can recover using digital forensic methodologies. We review the properties of Flash memory in mobile devices and demonstrate the pros and cons from a forensic 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 forensic perspective, then learn tactics to recover information that even forensic tools may not always be able to retrieve.
Forensic examiners must understand the concept of interpreting and analyzing the information on a variety of smartphones, as well as the limitations of existing methods for extracting data from these devices. This course day is packed full of knowledge and covers how to handle encryption issues, smartphone components, misfit devices (ones you may not commonly see), and SQLite overview and simple query language. We'll also introduce students to Android and how crack/bypass locked Android devices.
The SIFT Workstation used in class has been specifically loaded with a set of smartphone forensic tools that will be your primary toolkit and working environment for the week.

FOR585.2: Android Forensics
Overview
Focus: Android devices are among the most widely used smartphones in the world, which means they will surely be part of an investigation that will come across your desk. Unfortunately, gaining access to these devices isn't as easy as it used to be. Android devices contain substantial amounts of data that can be decoded and interpreted into useful information. However, without honing the appropriate skills to bypass locked Androids and correctly interpret the data stored on them, you will be unprepared for the rapidly evolving world of smartphone forensics. Android backups can be created for forensic analysis or by a user. Smartphone examiners need to understand the file structures and how to parse these data. Additionally, Android and Google cloud data store tons of valuable information. You will find Google artifacts from iOS users as well.
Digital forensic examiners must understand the file system structures of Android devices and how they store data in order to extract and interpret the information they contain. On this course day we will delve into the file system layout on Android devices and discuss common areas containing files of evidentiary value. Traces of user activities on Android devices are covered, as is recovery of deleted data residing in SQLite records and raw data files.
During hands-on exercises, you will use smartphone forensic tools to extract, decode, and analyze a wide variety of information from Android devices. You will use your SQLite examination skills, taught in the first course section, to draft queries to parse information that the commercial tools cannot support. When all else fails and the tools cannot extract information from newer Android devices, we will use ADB to manually interact and extract data of interest. We end this section by examining Android backups and cloud data associated with Android and Google. Methods for extracting and examining cloud data are covered and demonstrated.

FOR585.3: iOS Device Forensics
Overview
Focus: Apple iOS devices contain substantial amounts of data (including deleted records) that can be decoded and interpreted into useful information. Proper handling and parsing skills are needed for bypassing locked iOS devices and correctly interpreting the data. Without iOS instruction, you will be unprepared to deal with the iOS device that will likely be a major component in a forensic investigation.
This section dives right into iOS devices. Digital forensic examiners must understand the file system structures and data layouts of Apple iOS devices in order to extract and interpret the information they contain. To learn how to do this, we delve into the file system layout on iOS devices and discuss common areas containing files of evidentiary value. Encryption, decryption, file parsing, and traces of user activities are covered in detail.
During hands-on exercises, students will use smartphone forensic tools and methods to extract and analyze a wide variety of information from Android backups and iOS devices. Students will also be required to manually decode data that was deleted or are unrecoverable using smartphone forensic tools.

FOR585.4: iOS Backups, Malware and Spyware Forensics, and Detecting Evidence Destruction
Overview
Focus: iOS backups are extremely common and are found in the cloud and on hard drives. Users create backups, and we often find that our best data can be derived from creating an iOS backup for forensic investigation. This section will cover methodologies to extract backups and cloud data and analyze the artifacts for each. Malware affects a plethora of smartphone devices. We will examine various types of malware, how it exists on smartphones, and how to identify and analyze it. Most commercial smartphone tools help you identify malware, but none of them will allow you to tear down the malware to the level we cover in class. Up to five labs will be conducted on this day alone! The day ends with the students challenging themselves using tools and methods learned throughout the week to recover user data from a wiped smartphone.
iOS backup files are commonly part of digital forensic investigations. This course day provides students with a deep understanding of backup file contents, manual decoding, and parsing and cracking of encrypted backup file images. The methods learned during the previous course day are applied to the beginning of this section, as iOS backup files are essentially file system extractions. 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.
During hands-on exercises, students will use smartphone forensic tools and other methods to extract and analyze a wide range of information from iOS backups, an Android device containing mobile malware, and a wiped smartphone. Students will be required to manually decode data that was wiped, encrypted, or deleted, or that are unrecoverable using smartphone forensic tools.
Exercises

FOR585.5: Third-Party Application Analysis
Overview
Focus: This day starts with third-party applications across all smartphones and is designed to teach students how to leverage third-party application data and preference files to support an investigation. The rest of the day focuses heavily on secure chat applications, recovery of deleted application data and attachments, mobile browser artifacts, and knock-off phone forensics. The skills learned in this section will provide you with advanced methods for decoding data stored in third-party applications across all smartphones. We will show you what the commercial tools miss and teach you how to recover these artifacts yourself.
During hands-on exercises, students will use smartphone forensic tools to extract and analyze third-party application files of interest and then have to manually dig and recover data that are missed. Students will be required to manually decode data that was deleted or are unrecoverable using smartphone forensic tools and custom SQLite queries that they write themselves. The hands-on exercises will be a compilation of everything you have learned up until now in the course and will require the manual decoding of third-party application data from multiple smartphones. When this section ends. you will have proven to yourself that you have the skill set to recover artifacts that the forensic tools cannot recover.
Exercises
- Advanced third-party application exercise requiring students to use skills learned during the first four days of the course to manually decode communications stored in third-party application files across multiple smartphones

Hands-On Training & Labs
FOR585 features 31 hands-on labs and a final forensic challenge to ensure that students not only learn the material, but can also execute techniques to manually recover data. Some labs allow you to "choose your own adventure" so that students who may need to focus on a specific device can select relevant labs and go back to the others as time permits. The labs cover the following topics:
- Malware and Spyware -- Two labs are designed to teach students how to identify, manually decompile, and analyze malware recovered from an Android device. The processes used here reach beyond commercial forensic kits and methods. Bonus IPA and APK files are provided for practice. Two additional bonus labs are available on the USB.
- Android Analysis -- Four labs are designed to teach students how to manually crack locked devices, carve for deleted data, validate tool results, place the user behind an artifact, and parse third-party application files for user-created data not commonly parsed by commercial forensic tools. Open-source methods are utilized and highlighted where possible. An additional lab teaches students how to manually crack lockcodes from Android devices. A bonus lab encourages students to manually interact with a live device to pull relevant information using free methods.
- iOS Analysis -- Five labs are designed to teach students how to manually carve for deleted data, validate tool results, manually parse plists and databases of interest, and parse third-party application files for user-created data not commonly parsed by commercial forensic tools. In addition, methods for "tricking" your tools into parsing data from encrypted images are built into the labs. A bonus lab encourages students to manually interact with a live device to pull relevant information using free methods. There are other bonus iOS labs on the course USB.
- Backup File Analysis -- Three labs are designed to teach students how to parse data from iOS and Android backup files. These labs will drive students to parse data from databases, plists, and third-party application data. A bonus lab on BlackBerry backups is provided.
- Wiped Phone Analysis -- This is one of the more challenging labs for students, as the device used will have been wiped prior to acquisition. Students will be able to test all of the methods they learned during the course to see what can really be recovered from a wiped smartphone.
- BlackBerry 10 Analysis -- This all-encompassing lab provides students with a chance to tie external media (SIM cards) to a device, understand how data are manually carved and parsed, and understand how BlackBerry 10 applications differ from Android and iOS. Will you be able to identify a BlackBerry running Android applications? The methods used in this lab will apply to other smartphones that contain SIM cards and leverage third-party applications (Android, Windows Phone, Nokia, etc.)
- Knock-off Phone Analysis -- This lab focuses on handling knock-off devices, understanding the file system, and decoding the data not parsed by commercial tools.
- Third-Party Application Analysis -- These labs challenge students to examine third-party applications pulled from multiple smartphone devices, and to manually parse applications that are not commonly parsed by commercial tools.
- Parsing Application Databases -- These three labs provide students the opportunity to write SQL queries to parse tables of interest and to recover attachments associated with chats, deleted chats, and data from secure chat applications. The labs will challenge students to dig deep beyond what a commercial tool can offer.
- Browser Analysis -- This lab is focused on showing similarities and differences between computer and mobile browser artifacts. Your commercial tools may be good at parsing some evidence, but this lab will highlight what is missed!
- Smartphone Forensic Capstone -- The final challenge tests all that students have learned in the course. It features multiple smartphone devices used in various locations involving communication, third-party applications, Internet history, cloud and network activity, shared data, and more. The exercise encourages students to dig deep and showcase what they learned in FOR585 so that they can immediately apply it to their work when returning to their jobs.

Statements From Our Authors
"Digital forensic investigations almost always involve a smartphone or mobile device. Often the smartphone is the only form of digital evidence relating to the investigation and is the most personal device someone owns! Let's be honest: how many people share their smartphones like they do computers? Not many. Knowing how to recover all of the data residing on the smartphone is now an expectation in our field, and examiners must understand the fundamentals of smartphone handling and data recovery, accessing locked devices, and manually recovering data hiding in the background on the device. FOR585: Smartphone Forensic Analysis In-Depth provides this required knowledge to beginners in mobile device forensics and to mobile device experts. This course has something to offer everyone! There is nothing out there that competes with this course and its associated GIAC certification."- Heather Mahalik
"Eighty-five percent of the world's population today has a mobile phone. In the United States alone, almost half of these devices are smartphones. The tools and techniques for acquiring and analyzing these devices are changing every day. As the handsets become more sophisticated in the storage and obfuscation of personal user data, the tools and practitioners are in a race to uncover data related to investigations. The concepts covered in FOR585: Smartphone Forensic Analysis In-Depth will not only highlight some of the best tools available for acquiring and analyzing the smart devices on the market today, they will also provide examiners with best practices and techniques for delving deeper into smart devices as new applications and challenges arise. FOR585 keeps students ahead of the curve!" - Domenica Crognale
