This course has allowed me to hone my skills and knowledge.
I am migrating from a SOC analyst role to a forensic/IR position. This course is a great primer to make the transition.
THE CLOCK IS TICKING. YOU NEED TO PRIORITIZE THE MOST VALUABLE EVIDENCE FOR PROCESSING. LET US SHOW YOU HOW
FOR498: Battlefield Forensics & Acquisition Course will help you to:
- Acquire data effectively from:
- PCs, Microsoft Surface, and Tablet PCs
- Apple Devices, and Mac, and Macbooks
- RAM and Memory
- Smartphones and portable mobile devices
- Cloud storage and services
- Network storage repositories
- Produce actionable intelligence in 90 minutes or less
The first step in any investigation is the gathering of evidence. Digital forensic investigations are no different. The evidence used in this type of investigation is data, and this data can live in many varied formats and locations. You must be able to first identify the data that you might need, determine where that data resides, and, finally, formulate a plan and procedures for collecting that data.
With digital forensic acquisitions, you will typically have only one chance to collect data properly. If you manage the acquisition incorrectly, you run the risk of not only damaging the investigation, but more importantly, destroying the very data that could have been used as evidence.
With the wide range of storage media in the marketplace today, any kind of standardized methodology for all media is simply untenable. Many mistakes are being made in digital evidence collection, and this can cause the guilty to go free and, more importantly, the innocent to be incarcerated. The disposition of millions and millions of dollars can rest within the bits and bytes that you are tasked with properly collecting and interpreting.
An examiner can no longer rely on "dead box" imaging of a single hard drive. In today's cyber sphere, many people utilize a desktop, laptop, tablet, and cellular phone within the course of a normal day. Compounding this issue is the expanding use of cloud storage and providers, and the proper collection of data from all these domains can become quite overwhelming.
This in-depth digital acquisition and data handling course will provide first responders and investigators alike with the advanced skills necessary to properly respond to, identify, collect, and preserve data from a wide range of storage devices and repositories, ensuring that the integrity of the evidence is beyond reproach. Constantly updated, FOR498 addresses today's need for widespread knowledge and understanding of the challenges and techniques that investigators require when addressing real-world cases.
Numerous hands-on labs throughout the course will give first responders, investigators, and digital forensics teams practical experience needed when performing digital acquisition from hard drives, memory sticks, cellular phones, network storage areas, and everything in between.
During a digital forensics response and investigation, an organization needs the most skilled responders possible, lest the investigation end before it has begun. FOR498: Battlefield Forensics & Acquisition will train you and your team to respond, identify, collect, and preserve data no matter where that data hides or resides.
Course Syllabus
FOR498.1: Evidence File Quick Wins and Dealing with Smartphones
Overview
Any baker knows that if you bake with the wrong ingredients, the result will fail. The same holds true for digital evidence collection.
Investigators will often be responding in high-stress environments where many different entities are critically scrutinizing the collection process. Personnel need to be properly trained and equipped to work in less than optimal surroundings, and be confident that they have managed the scene, identified all necessary data, collected the data in a properly defensible manner, and maintained its integrity.
One of the most common scenarios that can cause headaches is receiving an evidence file (usually an E01), and being expected to provide answers immediately. The common approach is to mount the image and then start running carving and other tools against it. These automated tasks can take many hours (and sometimes days) just by themselves!
Portable devices bring their own set of challenges to the table. These devices are more ubiquitous than computers. Seldom is the case today that does not include a cellular device. Unfortunately, there is no standard for the cellular operating systems. Even within brands, there can be vastly different data storage. Today will introduce the student to several devices and the tools that will acquire them.

FOR498.2: Evidence Acquisition and Collection
Overview
There is no second chance when seizing or acquiring data. Make sure you get it right the first time.
Investigators and first responders should be armed with the latest tools, digital container access techniques, and enterprise methodologies to identify, access, and preserve evidence across a vast range of devices and repositories. Personnel must also be able to scale their identification and collection across thousands of systems in their enterprise. Enterprise and cloud storage collection techniques are now a requirement to track activity that has been intentionally and unintentionally spread across many devices. Responding to these many systems cannot be accomplished using the standard "pull the hard drive" forensic examination methodology. Such an approach will cause frustration and result in lost opportunities due to the time it takes to forensically image entire hard drives. Furthermore, investigators need actionable intelligence as quickly and responsibly as possible. This section lays the foundation for evidence collection, from initial arrival on a scene to the fundamentals of understanding data at rest and properly identifying devices, interfaces, and tools that will be necessary to affect a successful collection.
This course section will explore the myriad of acquisition hardware and software, not to mention adapters and identification, so we can make the best decisions about the data.

FOR498.3: Quick Win Forensics
Overview
Quick Win Forensics prioritizes locating, extracting, and processing the 1% of digital evidence you need to move a case forward.
Given that 99% of the necessary evidence typically will exist in 1-2% of the data acquired, it is easy to see how a great deal of time can be wasted following the normal procedures in today's digital forensics world. Instead, let's focus on this 1-2% and perform a very rapid triage collection that can be used to start our investigation sooner!
Far too often, computers are seized in an "on" state, and immediately powered down because, "that is how we've always done it." With today's computers this means you are throwing away (essentially destroying) many gigabytes of data. The RAM in a computer holds an incredibly important treasure trove of data, from keystrokes to network connections, running services, and, quite importantly, passwords and decryption keys.With the vastly increasing spread of file-less malware, in many cases the only place that evidence will exist is in memory. Another often-overlooked factor is full disk encryption. In cases like this, "live" acquisition will be your only hope.

FOR498.4: Non-Traditional and Cloud Acquisition
Overview
Cloud computing and storage is becoming more and more common. Do you know how to collect this critical data?
When we think about acquisition, it usually involves opening the side of the computer, removing the hard drive, connecting to a write blocker or imaging equipment, and completing the task. While this is not an inaccurate assessment, it does not address a great deal of the access and acquisition questions surrounding so much data today. If full disk imaging is necessary, then it is certainly easier and quicker to do it directly from the storage itself. But what happens with devices such as iPads, Surface Books, and other such equipment, where it is glue and not screws that hold them together?
Volume Shadow Copies also contain a wealth of historic data that is of great use to investigators. Knowing how to access and collect data from these shadow copies is critical in cases involving the Windows operating system.
Battlefield forensics is considered the bleeding edge of digital forensics. It requires in-depth knowledge of where the most valuable data resides on the computer and how to get at it as fast as possible. An effective battlefield forensicator needs to be extracting actionable intelligence in 90 minutes or less, butthe clock does not start when the forensic imaging is done. Rather. it starts from the moment you lay your hands on the device.
Learn how to identify and access data in non-traditional storage areas. In today's world so much data lives off site, and there are very few methods in place to access and properly acquire it. In this section, we will identify these locations, including SharePoint, Exchange, webmail, network locations, cloud storage, and social media, not to mention Dropbox, Google Drive, and the Internet of Things. This also includes RAID storage and how to best collect these devices regardless of configuration

FOR498.5: Apple Acquisition, Internet of Things, and Online Attribution
Overview
Apple must be approached entirely differently from traditional devices.
There are very few tools and techniques available when it comes to acquisition of Apple products, as compared to Windows. The tools that exist can be quite expensive, and free tools are simply few and far between. In this section, we will explore the fundamentals of acquiring data from Apple devices. We will acquire memory and identify systems that are running CoreStorage technology and full disk encryption. We will also visit the challenges posed by APFS. Many of the Apple systems are closed systems, in that you simply cannot remove the hard drive, as it is soldered directly to the motherboard. The uniqueness of the data storage demands alternative methods of acquisition.
In this course section, you'll learn how to access and forensically image iPads, MacBooks, and other HFS+ devices, working at the command line.
You have traced an artifact back to an IP, email, or web address. Now what? We will learn the best methods for determining attribution, from proper collection to legal documentation.
Not to be left out, the Internet of Things is pervasive. It is controlling our fridges, thermostats, security cameras, and door locks. It is listening passively and waiting patiently for an instruction to perform. Today you will learn how these devices communicate, and more importantly, who is controlling them.

FOR498.6: Beyond the Forensic Tools: The Deeper Dive
Overview
Tools fail, techniques become outdated, but do not let that hold you back.
The usefulness of file and stream carving cannot be overstated. Some data simply does not live in the defined file space that can be readily accessed by a viewer. From partially overwritten to deleted data, we will explore techniques you can employ when traditional tools fail.
Data carving is a skill that is increasingly important. Once the reference to a file is destroyed, how can the data still be recovered? File carving tools will assist in this, but examiners must understand the limitations of their tools. Without the proper pieces of the original file, a carver is useless.
At some point, you will be faced with non-functioning media. Learn about the inner workings of hard drives, and what you can (and cannot) do to revive them to a point where you can then create your forensic image. We will also be looking at the "best of breed" data recovery tools, from those that are free to those that cost many thousands of dollars.

Author Statement
"During my time as a Special Agent with the FBI, it became evident that the digital forensics community needed better methods to look at large amounts of data in an efficient manner to be able to get to answers quickly. As storage capacities increased, more traditional means began to take longer from a collection and analytical perspective. For this reason, I began creating triage software for use by the law enforcement community (and beyond). This problem has not changed since I left the FBI; in fact it has only continued to grow. For this reason, I decided to take a new approach to this problem, but this time in a way that could be given away to everyone in the digital forensics community. The result of this work is KAPE, which allows for rapid collection and analysis as determined by an incident responder. Of course, processing the data is only part of the equation, so this course spends a significant amount of time talking about acquisition--that is, how to get digital data from the devices we encounter. We not only talk about specific techniques for specific devices and situations, but for many of the topics covered, we provide the framework for how you can be successful when you encounter new devices. This course will focus on two key areas: getting the data that have the answers and extracting the answers from the data. We look forward to seeing you in class!" --Eric Zimmerman
"My digital forensics experience started in the mid 1990s. Back then, a hex editor was the most important tool that an examiner had. You had to understand data at rest in its most fundamental levels if you wanted to be effective at forensics. Fast forward to today and there is a myriad of tools to perform most any task that a forensic examiner might want to do. The by-product of this is that an examiner can be overwhelmed with not only the amount of tools available, but the amount of data that needs review. We recognized that the industry needed a more focused approach at the most important information on a hard drive, to the exclusion of the vast amounts of unnecessary noise. We also recognized that examiners need a better understanding of deleted data and how to extract some of the most important information that we have been missing. Finally, in recent years we have taken notice of the number of devices in use today that contain storage that cannot be removed from the machine. Couple this with live response and data that is encrypted at rest and we must recognize that certain approaches have to change. Thus FOR498 was born. We certainly hope you enjoy taking this class is much as we've enjoyed writing it, and our sincere hope is that this information allows you to become more effective at your craft." --Kevin Ripa
