SMARTPHONES HAVE MINDS OF THEIR OWN.

DON'T MAKE THE MISTAKE OF REPORTING SYSTEM EVIDENCE 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, 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: Advanced Smartphone Forensics 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 were put on the device. Examining and interpreting 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 17 hands-on labs that allow students to analyze different datasets from smart devices and leverage the best forensic tools 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 is 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, and encryption. This intensive six-day course offers the most unique and current instruction available, and it will arm you with mobile device forensic knowledge you can apply immediately 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 texts and apps can and will be used against them!

Course Syllabus

Overview

Focus: Although smartphone forensic concepts are similar to those of digital forensics, smartphone file system structures differ and require specialized decoding skills to interpret correctly 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, and data encoding concepts of smartphone components. Students will also become familiar with the forensic 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 and analyze it. Most commercial 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 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 categorized 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.

The SIFT Workstation has been specifically loaded with a set of smartphone forensic tools that will be your primary toolkit and working environment for the week.

Overview

Focus: We realize that not everyone examines BlackBerry devices. However, this section highlights pieces of evidence that can be found on multiple smartphones. Most importantly, we cover encrypted data on SD cards and how those data need to be acquired and examined. BlackBerry smartphones are designed to protect user privacy, but techniques taught in this section will enable the investigator to go beyond what the tools decode and manually recover data residing in database files of BlackBerry device file systems. Backup smartphone images are commonly found on external media and the cloud, and may be the only forensic acquisition method for newer iOS devices that are locked. Learning how to access and parse data from encrypted backup files may be the only lead to smartphone data relating to your investigation.

Forensic examiners must understand the concept of interpreting and analyzing the information on smartphones, as well as the limitations of existing methods for extracting data from these devices. This course day covers how to handle encryption issues, BlackBerry Enterprise Server data, and locked devices. Manual decoding of BlackBerry data will provide access to a vast amount of data that forensic tools seem to miss.

Both BlackBerry and iOS backup files are commonly part of digital forensic investigations. This section provides students with a deep understanding of backup file contents, manual decoding, and parsing and cracking of encrypted backup file images.

During hands-on exercises, students will use smartphone forensic tools to extract and analyze a wide variety of information from BlackBerry devices, SD cards with encrypted data, and iOS and BlackBerry backup files. Students will be required to manually decode data that were encrypted or deleted, or that are unrecoverable using smartphone forensic tools.

Developed by passionate practitioners with a high level of experience in the field, FOR585: Advanced Smartphone Forensics provides the elements you need to succeed in your investigations and thrive in the rapidly changing mobile device forensics environment." - Cindy Murphy

"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: Advanced Smartphone Forensics 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
