It is exceedingly rare to work any forensic investigation that doesn't have a network component. Endpoint forensics will always be a critical and foundational skill for DFIR professionals but overlooking their network communications is like ignoring security camera footage of a crime as it was committed. Whether you handle an intrusion incident, data theft case, employee misuse scenario, or are engaged in proactive adversary discovery, the network often provides an unparalleled view of the incident. Its evidence can provide the proof necessary to show intent, uncover attackers that have been active for months or longer, or may even prove useful in definitively proving a crime actually occurred.
FOR572: ADVANCED NETWORK FORENSICS: THREAT HUNTING, ANALYSIS AND INCIDENT RESPONSE was designed to cover the most critical skills needed for the increased focus on network communications and artifacts in today's investigative work, including numerous use cases. Many investigative teams are incorporating proactive threat hunting to their skills in which existing evidence is used with newly acquired threat intelligence to uncover evidence of previously unidentified incidents. Others focus on post-incident investigations and reporting. Still others engage with an adversary in real time, seeking to contain and eradicate the attacker from the victim's environment. In these situations and more, the artifacts left behind from attackers' communications can provide an invaluable view into their intent, capabilities, successes, and failures.
In FOR572, we focus on the knowledge necessary to examine and characterize communications that have occurred in the past or continue to occur. Even if the most skilled remote attacker has compromised a system with an undetectable exploit, the system must still communicate over the network. Without command-and-control and data extraction channels, the value of a compromised computer system drops to almost zero. Put another way: bad actors are talking - we'll teach you to listen.
This course covers the investigative tools, techniques, and procedures required to integrate network evidence sources into your investigations, with a focus on efficiency and effectiveness. You will leave this week with a well-stocked toolbox and the knowledge to use it on your first day back on the job. We will cover the full spectrum of network evidence, including high level NetFlow analysis, low-level pcap-based dissection, ancillary network log examination, and more. We cover how to leverage existing infrastructure devices that may contain months or years of valuable evidence as well as how to place new collection platforms while an incident is underway.
Whether you are a consultant responding to a client's site, a law enforcement professional assisting cybercrime victims and seeking prosecution of those responsible, an on-staff forensic practitioner, or a dedicated threat hunter, this course offers hands-on experience with real-world scenarios that will help take your work to the next level. Network defenders will benefit from the FOR572 perspective on security operations as they take on more incident response and investigative responsibilities. Those with existing endpoint-based DFIR experience can take their existing operating system or device knowledge and apply it directly to the network-based attacks that occur daily. In FOR572, we solve the same caliber of real-world problems without the use of disk or memory images.
Most of FOR572's hands-on labs have been developed in conjunction with the authors of FOR508, Advanced Incident Response, Threat Hunting, and Digital Forensics. In these shared scenarios, you'll quickly see why a hybrid approach to forensic examination that includes both host and network artifacts is ideal. Although our primary focus is on the network side of that equation, we will point out areas where the host perspective could provide additional context or where the network perspective gives deeper insight. Both former and future FOR508 students will appreciate the nexus between these extensive evidence sets.
The hands-on labs in this class cover a wide range of tools and platforms, including the venerable tcpdump and Wireshark for packet capture and analysis; NetworkMiner for artifact extraction; and open-source tools including nfdump, tcpxtract, tcpflow, and more. Newly added tools in the course include the free and open-source SOF-ELK platform - a VMware appliance pre-configured with the Elastic stack and tailored to DFIR and security operations workflows. This "big data" platform includes the Elasticsearch storage and search database, the Logstash ingest and parsing engine, and the Kibana graphical dashboard interface. Together with the custom SOF-ELK configuration files, the platform gives forensicators a ready-to-use platform for log and NetFlow analysis. For full-packet analysis and hunting at scale, the free and open-source Arkime platform is also covered and used in a hands-on lab. Through all the in-class labs, shell scripting skills are highlighted as quick and easy ways to rip through hundreds of thousands or even millions of data records.
FOR572 is an advanced course - we hit the ground running on day one. Bring your entire bag of skills: forensic techniques and methodologies, full-stack networking knowledge (from the physical medium all the way up to user-facing services), Linux shell utilities, and everything in between. They will all benefit you throughout the course material as you FIGHT CRIME. UNRAVEL INCIDENTS...ONE BYTE (OR PACKET) AT A TIME.

Network connection logging, commonly called NetFlow, is often the single most valuable source of evidence in network investigations. Many organizations have extensive archives of flow data due to its minimal storage requirements. Since NetFlow does not capture any content of the transmission, many legal issues regarding long-term retention are mitigated. Even without content, NetFlow provides an excellent means of guiding an investigation and characterizing an adversary's activities from pre-attack through operations on objective. Whether for moving within a victim's environment or for data exfiltration, adversaries must move their quarry around using various file access protocols. By knowing some of the more common file access and transfer protocols, a forensicator can quickly identify an attacker's theft actions.
Just as even a fuzzy photo can provide valuable leads in a traditional investigation, NetFlow data can provide a network forensicator with extremely high-value intelligence about network communications. The key to extracting that value is in knowing how to use NetFlow evidence to drive more detailed investigative activities.
NetFlow is also an ideal technology to use in baselining typical behavior of an environment, and therefore, deviations from that baseline that may suggest areas for further investigation. Threat hunting teams can also use NetFlow to identify prior connections consistent with newly identified suspicious endpoints or traffic patterns.
In this section, you will learn the contents of typical NetFlow protocols, as well as common collection architectures and analysis methods. You'll also discuss how to distill full-packet collections to NetFlow records for quick initial analysis before diving into more cumbersome pcap files.
You'll then examine the File Transfer Protocol, including how to reconstruct specific files from an FTP session. While FTP is commonly used for data exfiltration, it is also an opportunity to refine protocol analysis techniques, due to its multiple-stream nature.
Lastly, you'll explore a variety of the network protocols unique to a Microsoft Windows or Windows-compatible environment. Significant time will be spent exploring the SMB protocol, used for file transfers and countless other purposes in a Microsoft Windows domain structure. Attackers frequently use these protocols to "live off the land" within the victim's environment. By using existing and expected protocols, the adversary can hide in plain sight and avoid deploying malware that could tip off the investigators to their presence and actions.
Commercial tools are an important part of a network forensicator's toolkit. We'll discuss the benefits specific commercial tools may provide, as well as how they may best be integrated into an investigative workflow. With the runaway adoption of wireless networking, investigators must also be prepared to address the unique challenges this technology brings to the table. However, regardless of the protocol being examined or budget used to perform the analysis, having a means of exploring full-packet capture is a necessity, and having a toolkit to perform this at scale is critical.
Commercial tools hold clear advantages in some situations a forensicator may typically encounter. Most commonly, this centers on scalability. Many open-source tools are designed for tactical or small-scale use. Whether using them for large-scale deployments or for specific niche functionalities, these tools can immediately address many investigative needs.
Additionally, we will address the forensic aspects of wireless networking. We will cover similarities with and differences from traditional wired network examinations, as well as what interesting artifacts can be recovered from wireless protocol fields. Some inherent weaknesses of wireless deployments will also be covered, including how attackers can leverage those weaknesses during an attack and how they can be detected.
