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. 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 worse damage to the organization. For the incident responder, this process is known as " threat hunting ". FOR508 teaches advanced skills to hunt, identify, counter, and recover from a wide range of threats within enterprise networks, including APT nation-state adversaries, organized crime syndicates, and hactivists.

What You Will Learn

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 or contain propagating ransomware. 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 ransomware syndicates.

FOR508: Advanced Incident Response and Threat Hunting Course will help you to:

  • Understand attacker tradecraft to perform compromise assessments
  • Detect how and when a breach occurred
  • Quickly identify compromised and infected systems
  • Perform damage assessments and determine what was read, stolen, or changed
  • Contain and remediate incidents of all types
  • Track adversaries and develop threat intelligence to scope a network
  • Hunt down additional breaches using knowledge of the adversary
  • Build advanced forensics skills to counter anti-forensics and data hiding from technical subjects

The course exercises and final challenges illustrate real attacker traces found via end point artifacts, event logs, system memory, and more:

  • Phase 1 - Patient zero compromise and malware C2 beacon installation
  • Phase 2 - Privilege escalation, lateral movement to other systems, malware utilities download, installation of additional beacons, and obtaining domain admin credentials
  • Phase 3 - Searching for intellectual property, network profiling, business email compromise, dumping enterprise hashes
  • Phase 4 - Find exfiltration point, collect and stage data for theft
  • Phase 5 - Exfiltrate files from staging server, perform cleanup and set long-term persistence mechanisms (alternatively this phase would be used to deploy ransomware)

Business Takeaways:

  • Understand attacker tradecraft to perform proactive compromise assessments
  • Upgrade detection capabilities via better understanding of novel attack techniques, focus on critical attack paths, and knowledge of available forensic artifacts
  • Develop threat intelligence to track targeted adversaries and prepare for future intrusion events

  • Overview

    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 security teams are proving that these threats can be managed and mitigated. FOR508 aims to bring those hard-won lessons into the classroom.

    This course was designed to help organizations increase their capability to detect and respond to intrusion events. This is an achievable goal and begins by teaching 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. To keep pace, 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 and damage mitigation. 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 and attack 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), PowerShell, and WMI-based attacks in particular have become standard operating procedure for advanced adversaries and students get a lot of practice with tools and techniques to identify such attacks at scale. We end the day with an in-depth discussion of Microsoft credentialing. The complexity of credentials in the modern enterprise cannot be overstated and credentials are the number one vulnerability present in every network. By understanding the tools and techniques being used to target credentials, students learn how to prevent, detect, and mitigate these devastating attacks.

  • Overview

    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. 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 internal lateral movement. 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.

  • Overview

    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 (notably EDR) and the mainstay of successful incident response and threat hunting teams. Memory forensics can be extraordinarily effective at finding evidence of worms, rootkits, PowerShell attacks, ransomware precursors, 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 analysts a solid foundation of advanced memory forensic skills to super-charge investigations, regardless of the toolset employed.

  • Overview

    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.

    Exercises
    • 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
    • Identify root cause of an intrusion
    • Learn how to filter system artifact, file system, and registry timelines to target the most important data sources efficiently

    Advanced adversaries are always improving. We must keep pace

    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. Criminal and ransomware syndicates have become particularly aggressive in their use of anti-forensic techniques. In this section, we focus on recovering 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 rapid scoping of an intrusion and mitigating damage. In some cases, these deep-dive techniques could be the only means for proving that an attacker was active on a system of interest and ultimately determining root cause. While very germane to intrusion cases, these techniques are applicable in nearly every forensic investigation.

  • Overview

    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.

    Topics
    • 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
    • Witness and participate in a team-based approach to incident response.
    • 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 was the network breached?

    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?

    ADDITIONAL NOTES:

    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.

    If you have additional questions about the laptop specifications, please contact laptop_prep@sans.org.

Prerequisites

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. The course does not cover the basics of incident response policies or digital forensics.

We recommend that you should have a background in FOR500: Windows Forensics prior to attending this course.

Laptop Requirements

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)
  • CRITICAL NOTE: Apple systems using the M1 processor line cannot perform the necessary virtualization functionality and therefore cannot in any way be used for this course.
  • 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.

  • 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, but at least 200GB free space is required on the host for course Virtual Machines. The real data used in this course leads to very large files!
  • 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.

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.

PLEASE INSTALL THE FOLLOWING SOFTWARE PRIOR TO CLASS:

  1. 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.
  2. Download and install 7Zip (for Windows Hosts) or Keka (macOS).

Your course media will now be delivered via download. The media files for class will be large, 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 soon 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. This class uses an electronic workbook in addition to the PDFs. We have found that a second monitor and/or a tablet device can be useful for keeping the class materials visible while the instructor is presenting or while you are working on lab exercises.

Author Statement

"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 analyst 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."

- Rob Lee

"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 nimbler 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."

It's hard to really say something that will properly convey the amount of mental growth I have experienced in this training.

I have been doing digital forensics for 13+ years. This course has still managed to build on my existing knowledge and made me challenge some pre-conceptions. It has given me tons of ideas to take home and develop to improve our enterprises security posture.
