What You Will Learn
ADVANCED THREATS ARE IN YOUR NETWORK - IT'S TIME TO GO HUNTING!
FOR508: Advanced Incident Response and Threat Hunting Course will help you to:
- Detect how and when a breach occurred
- Identify compromised and affected systems
- Perform damage assessments and determine what was stolen or changed
- Contain and remediate incidents
- Develop key sources of threat intelligence
- Hunt down additional breaches using knowledge of the adversary
DAY 0: A 3-letter government agency contacts you to say an advanced threat group is targeting organizations like yours, and that your organization is likely a target. They won't tell how they know, but they suspect that there are already several breached systems within your enterprise. An advanced persistent threat, aka an APT, is likely involved. This is the most sophisticated threat that you are likely to face in your efforts to defend your systems and data, and these adversaries may have been actively rummaging through your network undetected for months or even years.
This is a hypothetical situation, but the chances are very high that hidden threats already exist inside your organization's networks. Organizations can't afford to believe that their security measures are perfect and impenetrable, no matter how thorough their security precautions might be. Prevention systems alone are insufficient to counter focused human adversaries who know how to get around most security and monitoring tools.
The key is to constantly look for attacks that get past security systems, and to catch intrusions in progress, rather than after attackers have completed their objectives and done significant damage to the organization. For the incident responder, this process is known as "threat hunting". Threat hunting uses known adversary behaviors to proactively examine the network and endpoints in order to identify new data breaches.
Threat hunting and Incident response tactics and procedures have evolved rapidly over the past several years. Your team can no longer afford to use antiquated incident response and threat hunting techniques that fail to properly identify compromised systems, provide ineffective containment of the breach, and ultimately fail to rapidly remediate the incident. Incident response and threat hunting teams are the keys to identifying and observing malware indicators and patterns of activity in order to generate accurate threat intelligence that can be used to detect current and future intrusions.
This in-depth incident response and threat hunting course provides responders and threat hunting teams with advanced skills to hunt down, identify, counter, and recover from a wide range of threats within enterprise networks, including APT nation-state adversaries, organized crime syndicates, and hacktivists. Constantly updated, FOR508: Advanced Incident Response and Threat Hunting addresses today's incidents by providing hands-on incident response and threat hunting tactics and techniques that elite responders and hunters are successfully using to detect, counter, and respond to real-world breach cases.
The course uses a hands-on enterprise intrusion lab -- modeled after a real-world targeted APT attack on an enterprise network and based on APT group tactics to target a network -- to lead you to challenges and solutions via extensive use of the SIFT Workstation and best-of-breed investigative tools.
During the intrusion and threat hunting lab exercises, you will identify where the initial targeted attack occurred and how the adversary is moving laterally through multiple compromised systems. You will also extract and create crucial cyber threat intelligence that can help you properly scope the compromise and detect future breaches.
During a targeted attack, an organization needs the best incident response team in the field. FOR508: Advanced Incident Response and Threat Hunting will train you and your team to respond, detect, scope, and stop intrusions and data breaches.

One of the biggest complaints you hear in the threat hunting and incident response community is the lack of realistic intrusion data. Most real-world intrusion data are simply too sensitive to be shared.
The FOR508 course authors created a realistic scenario based on experiences surveyed from a panel of responders who regularly combat targeted APT attacks. They helped review and guide the targeted attack "script" used to create the scenario. The result is an incredibly rich and realistic attack scenario across multiple enterprise systems. This APT attack lab forms the basis for training during the week. The network was set up to mimic a standard "protected" enterprise network using standard compliance checklists:
- Full auditing turned on per recommended Federal Information Security Management Act guidelines
- Windows domain controller (DC) set up and configured; DC hardened similarly to what is seen in real enterprise networks
- Systems installed with the real software on them that is used (Office, Adobe, Skype, Tweetdeck, Email, Dropbox, Firefox, Chrome)
- Fully patched systems (patches are automatically installed)
- Endpoint Detection and Response (EDR) agents
- Enterprise A/V and on-scan capability based on the Department of Defense's Host-based Security System

There are ways to gain an advantage against adversaries targeting you -- it starts with the right mindset and knowing what works.
The last decade has not been kind to network defenders. Threats to the modern enterprise are legion and attackers have used the enormous complexity of enterprise networks against us. But the tide is shifting. Over the past decade, we have seen a dramatic increase in sophisticated attacks against organizations. Nation-state attacks originating from the intelligence services of countries like China and Russia, often referred to as Advanced Persistent Threat (APT) actors, have proved difficult to suppress. Massive financial attacks from the four corners of the globe have resulted in billions of dollars in losses. Ransomware and extortion became an existential threat almost overnight. While the odds are stacked against us, the best teams out there are proving that these threats can be managed and mitigated. The adversary is good and getting better. Are we learning how to counter them? Yes, we are.
This course was designed to help organizations increase their capability to detect and respond to intrusions. This is an achievable goal and begins by teaching you the tools and techniques necessary to find evil in your network. This course is designed to make you and your organization an integral part of the solution. Incident responders and threat hunters must be armed with the latest tools, analysis techniques, and enterprise methodologies to identify, track, and contain advanced adversaries with the ultimate goal of rapid remediation of incidents. Further, incident response and threat hunting analysts must be able to scale their efforts across potentially thousands of systems in the enterprise. We start the day by examining the six-step incident response methodology as it applies to incident response for advanced threat groups. The importance of developing cyber threat intelligence to impact the adversaries' "kill chain" is discussed and forensic live response techniques and tactics are demonstrated that can be applied both to single systems and across the entire enterprise.
Understanding attacks is critical to being able to detect and mitigate them. We start our education of attacker techniques on day one, learning common malware characteristics and diving deep into techniques used by adversaries to maintain persistence in the network. Persistence is typically completed early in the attack cycle and students will learn hunting techniques to audit the network and accomplish early discovery. Living off the land binaries (local tools available in most environments) and WMI-based attacks in particular have become standard operating procedure for advanced adversaries and we end the day working with tools and techniques to identify such attacks at scale.

Even the most advanced adversaries leave footprints everywhere. Learn the secrets of the best hunters.
Cyber defenders have a wide variety of tools and artifacts available to identify, hunt, and track adversary activity in a network. Each attacker action leaves a corresponding artifact, and understanding what is left behind as footprints can be crucial to both red and blue team members. Attacks follow a predictable pattern, and we focus our detective efforts on immutable portions of that pattern. As an example, at some point an attacker will need to run code to accomplish their objectives. We can identify this activity via application execution artifacts. The attacker will also need one or more accounts to run code. Consequently, account auditing is a powerful means of identifying malicious actions. An attacker also needs a means to move throughout the network, so we look for artifacts left by the relatively small number of ways there are to accomplish this part of their mission. In this section, we cover common attacker tradecraft and discuss the various data sources and forensic tools you can use to identify malicious activity in the enterprise.

Using memory analysis sometimes feels like cheating -- finding active attacks shouldn't be this easy.
Memory forensics has come a long way in just a few years. It is now a critical component of many advanced tool suites and the mainstay of successful incident response and threat hunting teams. Memory forensics can be extraordinarily effective at finding evidence of worms, rootkits, PowerShell, and advanced malware used by targeted attackers. In fact, some fileless attacks may be nearly impossible to unravel without memory analysis. Memory analysis was traditionally the domain of Windows internals experts and reverse engineers, but new tools, techniques, and detection heuristics have greatly leveled the playing field making it accessible today to all investigators, incident responders, and threat hunters. Further, understanding attack patterns in memory is a core analyst skill applicable across a wide range of endpoint detection and response (EDR) products, making those tools even more effective. This extremely popular section will cover many of the most powerful memory analysis capabilities available and give you a solid foundation of advanced memory forensic skills to super-charge investigations, regardless of the toolset employed.

Timeline analysis will change the way you approach digital forensics, threat hunting, and incident response...forever.
Learn advanced incident response and hunting techniques uncovered via timeline analysis directly from the authors who pioneered timeline analysis tradecraft. Temporal data is located everywhere on a computer system. Filesystem modified/access/creation/change times, log files, network data, registry data, and browser history files all contain time data that can be correlated and analyzed to rapidly solve cases. Pioneered by Rob Lee as early as 2001, timeline analysis has grown to become a critical incident response, hunting, and forensics technique. New timeline analysis frameworks provide the means to conduct simultaneous examinations on a multitude of systems across a multitude of forensic artifacts. Analysis that once took days now takes minutes.
This section will step you through two primary methods of building and analyzing timelines used during advanced incident response, threat hunting, and forensic cases. Exercises will show analysts how to create timelines and how to introduce the key analysis methods necessary to help you use those timelines effectively in your cases.
- Detecting malware defense evasion techniques
- Using timeline analysis, track adversary activity by hunting an APT group's footprints of malware, lateral movement, and persistence
- Target hidden and time-stomped malware and utilities that advanced adversaries use to move in the network and maintain their presence
- Track advanced adversaries' actions second-by-second through in-depth super-timeline analysis
- Observe how attackers laterally move to other systems in the enterprise by watching a trail left in filesystem times, registry, event logs, shimcache, and other temporal-based artifacts

Advanced adversaries are good. We must be better.
Attackers commonly take steps to hide their presence on compromised systems. While some anti-forensics steps can be relatively easy to detect, others are much harder to deal with. As such, it's important that forensic professionals and incident responders are knowledgeable on various aspects of the operating system and file system which can reveal critical residual evidence. In this section, we focus primarily on the file system to recover files, file fragments, and file metadata of interest to the investigation. These trace artifacts can help the analyst uncover deleted logs, attacker tools, malware configuration information, exfiltrated data, and more. This often results in a deeper understanding of the attacker TTPs and provides more threat intelligence for thorough scoping the intrusion. In some cases, these deep-dive techniques could be the only means for proving that an attacker was active on a system of interest.

This incredibly rich and realistic enterprise intrusion exercise is based on a real-world advanced persistent threat (APT) group. It brings together techniques learned earlier in the course and tests your newly acquired skills in an investigation into an attack by an advanced adversary. The challenge brings it all together using a real intrusion into a complete Windows enterprise environment. You will be asked to uncover how the systems were compromised in the initial intrusion, find other compromised systems via adversary lateral movement, and identify intellectual property stolen via data exfiltration. You will walk out of the course with hands-on experience investigating a real attack, curated by a cadre of instructors with decades of experience fighting advanced threats from attackers ranging from nation-states to financial crime syndicates and hacktivist groups.
- The Intrusion Forensic Challenge will ask each incident response team to analyze multiple systems in an enterprise network with many endpoints.
- Learn to identify and track attacker actions across an entire network finding initial exploitation, reconnaissance, persistence, credential dumping, lateral movement, elevation to domain administrator, and data theft/exfiltration.
- Discover evidence of some of the most common and sophisticated attacks in the wild including Cobalt Strike, Metasploit, PowerShell exploit frameworks, and custom nation-state malware.
- During the challenge, each incident response team will be asked to answer key questions and address critical issues in the different categories listed below, just as they would during a real breach in their organizations:
IDENTIFICATION AND SCOPING:
1. How and when did the APT group breach our network?
2. List all compromised systems by IP address and specific evidence of compromise.
3. When and how did the attackers first laterally move to each system?
CONTAINMENT AND THREAT INTELLIGENCE GATHERING:
4. How and when did the attackers obtain domain administrator credentials?
5. Once on other systems, what did the attackers look for on each system?
6. Find exfiltrated email from executive accounts and perform damage assessment.
7. Determine what was stolen: Recover any attacker archives, find encryption passwords, and extract the contents to verify exfiltrated data.
8. Collect and list all malware used in the attack.
9. Develop and present cyber threat intelligence based on host and network indicators of compromise.
REMEDIATION AND RECOVERY:
10. What level of account compromise occurred. Is a full password reset required during remediation?
11. Based on the attacker techniques and tools discovered during the incident, what are the recommended steps to remediate and recover from this incident?
a. What systems need to be rebuilt?
b. What IP addresses need to be blocked?
c. What countermeasures should we deploy to slow or stop these attackers if they come back?
d. What recommendations would you make to detect these intruders in our network again?
If you have attended FOR500, you may want to bring your copy of the FOR500 - Windows SIFT Workstation Virtual Machine, as you can use it for the final challenge and for many of the exercises in FOR508.
Bring/install any other forensic tool you feel could be useful (Splunk, EnCase, FTK, etc). For the final challenge at the end of the course, you can utilize any forensic tool to help you and your team perform the analysis, including commercial capabilities. If you have any dongles, licensed software, etc., you are free to use them.
Please do not plan to use the version of the SIFT Workstation downloaded from the Internet. We will provide you with a version specifically configured for the FOR508 materials on Day 1 of the course.

Threat Hunting and APT Intrusion Incident Response
FOR508 is an advanced incident response and threat hunting course that focuses on detecting and responding to advanced persistent threats and organized crime threat groups. We do not cover the introduction or basics of incident response, Windows digital forensics, or hacker techniques in this course.
We recommend that you should have a background in FOR500: Windows Forensics prior to attending this course.
Important! Bring your own system configured according to these instructions!
A properly configured system is required to fully participate in this course. If you do not carefully read and follow these instructions, you will likely leave the class unsatisfied because you will not be able to participate in hands-on exercises that are essential to this course. Therefore, we strongly urge you to arrive with a system meeting all the requirements specified for the course.
This is common sense, but we will say it anyway. Back up your system before class. Better yet, do not have any sensitive data stored on the system. SANS can't responsible for your system or data.
MANDATORY FOR508 SYSTEM HARDWARE REQUIREMENTS:
- CPU: 64-bit Intel i5/i7 (4th generation+) - x64 bit 2.0+ GHz processor or more recent processor is mandatory for this class (Important - Please Read: a 64-bit system processor is mandatory)
- It is critical that your CPU and operating system support 64-bit so that our 64-bit guest virtual machine will run on your laptop. VMware provides a free tool for Windows that will detect whether or not your host supports 64-bit guest virtual machines. For further troubleshooting, this article also provides good instructions for Windows users to determine more about the CPU and OS capabilities. For Macs, please use this support page from Apple to determine 64-bit capability.
BIOS settings must be set to enable virtualization technology, such as "Intel-VT".
Be absolutely certain you can access your BIOS if it is password protected, in case changes are necessary. Test it!
- 16 GB (Gigabytes) of RAM or higher is mandatory for this class (Important - Please Read: 16 GB of RAM or higher of RAM is mandatory and minimum.
- USB 3.0 Type-A port is required. At least one open and working USB 3.0 Type-A port is required. (A Type-C to Type-A adapter may be necessary for newer laptops.) (Note: Some endpoint protection software prevents the use of USB devices - test your system with a USB drive before class to ensure you can load the course data.)
- 350 Gigabytes of Free Space - Note that about 150 GB is required for downloaded evidence files. This data can be stored on an external drive
- Local Administrator Access is required. This is absolutely required. Don't let your IT team tell you otherwise. If your company will not permit this access for the duration of the course, then you should make arrangements to bring a different laptop.
- Wireless 802.11 Capability
MANDATORY FOR508 HOST OPERATING SYSTEM REQUIREMENTS:
- Host Operating System: Latest version of Windows 10 or macOS 10.15.x
- Please note: It is necessary to fully update your host operating system prior to the class to ensure you have the right drivers and patches installed to utilize the latest USB 3.0 devices.
Note: Apple systems using the M1 processor cannot perform the necessary virtualization at this time and cannot be used for this course.
PLEASE INSTALL THE FOLLOWING SOFTWARE PRIOR TO CLASS:
- Download and install VMware Workstation Pro 15.5.X+, VMware Player 15.5.X+ or Fusion 11.5+ on your system prior to class beginning. If you do not own a licensed copy of VMware Workstation or Fusion, you can download a free 30-day trial copy from VMware. VMware will send you a time-limited serial number if you register for the trial at their website.
- Download and install 7Zip (for Windows Hosts) or Keka (macOS).
Your course media will now be delivered via download. The media files for class can be large, some in the 40 - 50 GB range. You need to allow plenty of time for the download to complete. Internet connections and speed vary greatly and are dependent on many different factors. Therefore, it is not possible to give an estimate of the length of time it will take to download your materials. Please start your course media downloads as you get the link. You will need your course media immediately on the first day of class. Waiting until the night before the class starts to begin your download has a high probability of failure.
SANS has begun providing printed materials in PDF form. Additionally, certain classes are using an electronic workbook in addition to the PDFs. The number of classes using eWorkbooks will grow quickly. In this new environment, we have found that a second monitor and/or a tablet device can be useful by keeping the class materials visible while the instructor is presenting or while you are working on lab exercises.
"In describing the advanced persistent threat (APT) and advanced adversaries, many experts have said, 'There are people smarter than you, who have more resources than you, and who are coming for you. Good luck with that.' They were not joking. The results over the past several years clearly indicate that hackers employed by nation-states and organized crime are racking up success after success. The APT has compromised hundreds of organizations. Organized crime organizations using botnets are exploiting Automated Clearing House (ACH) fraud daily. Similar groups are penetrating banks and merchants, stealing credit card data. Fortune 500 companies are beginning to detail data breaches and hacks in their annual stockholder reports.
"In other words, the enemy is getting better and bolder, and their success rate is impressive.
"We can stop them, but to do so, we need to field more sophisticated incident responders and digital forensics investigators. We need lethal digital forensics experts who can detect and eradicate advanced threats immediately. A properly trained incident responder could be the only defense your organization has left during a compromise. Forensics 508: Advanced Digital Forensics, Incident Response, and Threat Hunting is crucial training for you to become the lethal forensicator who can step up to these advanced threats. The enemy is good. We are better. This course will help you become one of the best."

"We live in a world of unimaginable amounts of data stored on immensely large and complicated networks. Our adversaries use this complexity against us to slice through our defenses and take virtually anything they want, anytime they want it. While this is our current state, it will not be our future. Incident response is at an inflection point. Old models are being upgraded to make defenders more effective and nimble in response to more sophisticated and aggressive attackers. The most successful incident response teams are evolving rapidly due to near-daily interaction with adversaries. New tools and techniques are being developed, providing better visibility and making the network more defensible. There are an increasing number of success stories, with organizations quickly identifying intrusions and rapidly remediating them.
We created this course to build upon those successes. Like the field itself, the course is continuously updated, bringing the latest advances into the classroom. Whether you are just moving into the incident response field or are already leading hunt teams, FOR508 facilitates learning from others' experiences and develops the necessary skills to take you to the next level."
