Hunting Evil with Wireshark

Michael Wylie, MBA, CISSP, Sr. Manager, Threat Hunting

This workshop will take attendees’ Wireshark skills to the next level with a heavy emphasis on incident response, threat hunting, and identifying anomalous network traffic. This workshop will begin with a brief introduction to Wireshark and other Network Security Monitoring (NSM) tools/concepts. Throughout the workshop, we’ll examine what different attacks and malware look like while using Wireshark. Attendees will then have hands-on time in the lab to search for Indicators of Compromise (IOCs) and TTPs utilizing staged packet capture files. Labs start out easy and quickly progress in difficulty. There will be plenty of take-home labs for additional practice.

APT Hunting with Splunk

John Stoner, Principal Security Strategist at Splunk

Interested in practicing your hunting skills? If so, this is the workshop for you. Using a real-worldish dataset, this workshop will teach you how to hunt the “fictional” APT group Violent Memmes. We discuss the Diamond model, building hypotheses, LM Kill Chain, and MITRE ATT&CK and how these concepts can frame your hunting. Using Splunk, we will hunt for APT activity riddling a small startup's environment. During the event, we will be presented with a "notable event" and pull on that string to conduct our own hunts based on indicators that we uncover or are identified. Depending on the hunt, we will uncover persistence, exfiltration, c2 and other adversary tactics. We may even find some PowerShell scripts. We will regroup and review the specific hunt conducted and discuss the timeline of events, a narrative that could be shared with others on your team, the artifacts that were uncovered to better identify potential future hunts, ATT&CK techniques referenced as well as what could be operationalized. At the end, we will highlight some additional datasets and content that you can take with you and try newly learned techniques yourself.

John Stoner (Twitter: @stonerpsu) is a Principal Security Strategist at Splunk where he enjoys writing, problem solving and building stuff, including APT Scenarios. When not doing cyber things, you can find him watching his boys play hockey, reading or binge-watching TV series that everyone else has already seen.

Security Investigations with Splunk

Robert Wagner, Splunk and Co-Founder of Hak4Kidz

Investigating with Splunk is a hands-on workshop designed to familiarize participants with how to investigate incidents using Splunk and open source. This workshop provides users a way to gain experience searching in Splunk to answer specific questions related to an investigation. These questions are similar to what would be asked in their own organizations. The workshop leverages the popular Boss of the SOC (BOTS) dataset in a question-and-answer format. Users will leave with a better understanding of how Splunk can be used to investigate in their enterprise. The class includes access to download the free “Investigating with Splunk” app that can be used to review the exercises after the class.

Intrusion Analysis and Threat Hunting with Suricata

Josh Stroschein, Director of IT Training at Open Information Security Foundation (OISF)
Peter Manev, CSO of Stamus Networks

In today’s threat landscape, sophisticated adversaries have routinely demonstrated the ability to compromise enterprise networks and remain hidden for extended periods of time. In Intrusion Analysis and Threat Hunting with open-source Tools, you will learn how to dig deep into network traffic to identify key evidence that a compromise has occurred, learn how to deal with new forms of attack, and develop the skills necessary to proactively search for evidence of new breaches. We will explore key phases of adversary tactics and techniques - from delivery mechanisms to post-infection traffic to get hands-on analysis experience. Open-source tools such as Suricata and Moloch will be utilized to generate data, perform exhaustive traffic analysis, and develop comprehensive threat hunting strategies. By the end of this workshop, you will have the knowledge and skills necessary to discover new threats in your network.

Hands-On TCP Deep Dive with Wireshark

Chris Greer, Network Analyst and Wireshark Instructor at Packet Pioneer

A solid understanding of how TCP works is critical for anyone interested in cybersecurity. Almost all enumeration, incident response, and traffic forensics require the analyst to dig into and interpret TCP flows. In this video we will take a look at how TCP is used to investigate and establish connections, how data is transmitted and acknowledged, how connections are torn down, and what problem indicators should catch our eye in Wireshark. This video welcomes all cybersecurity and Wireshark experience levels.

Chris Greer is a network analyst and Wireshark instructor for Packet Pioneer, a Wireshark University partner. He has focused much of his career at the transport layer, specifically TCP, specializing in how this core protocol works to deliver applications, services, and attacks between systems.

*nix Processes. Starting, Stopping, and Everything In Between

Nick Roy

Core Topic: Operating Systems: *nix

Recording discusses Linux and Unix processes, starting with a high level overview of what a process is and what the key components are. We then take a look at how the operating system manages multiple processes, what are the main components of a running process, and finally some common syscalls used in Linux when creating processes. Finally, we look at a few code samples to show how these calls are used with a simple shell. All code can be found here to compliment the video:

Seeing the Forest Through the Trees – Foundations of Event Log Analysis

Jake Williams, CTO of BreachQuest

Core Topic: System Forensics

During an incident, everyone knows you need to review the logs – but what are they actually telling you? There's a wealth of information to be had in your logs event logs, but most analysts miss the forest because they don't understand the trees. In this talk, Jake will walk you through some of the most impactful event logs to focus on in your analysis. We'll target some old favorites covering login events, service creation, and process execution. We'll also examine task scheduler logs, useful in uncovering lateral movement and privilege escalation. Finally, we'll discuss some of the new event logs available in Windows 10 (if only you enable them first). If you don't want to be barking up the wrong tree during your next insider investigation or getting axed because you failed to identify the lateral movement attempts, make sure to watch this video.

Jake Williams (Twitter: @malwarejake) is an incident responder, red teamer, occasional vCISO, and prolific infosec shitposter. He has traveled the world, but isn't welcome in China or Russia (and avoids most countries they have extradition treaties with). When not speaking at a conference like this one, it's a good bet that Jake is engaged in hand to hand combat with an adversary rooted deep in a network or engineering ways to keep them out. Jake's career in infosec started in the intelligence community, but has taken around the world securing networks of all shapes and sizes, from utilities to hospitals to manufacturing plants.

The War for Control of DNS Encryption

Dr. Paul Vixie, Chairman and CEO and Cofounder of Farsight Security, Inc.

Core Topic: Core Networking

Pervasive monitoring of the Internet by both government, corporate, and criminal actors has triggered an encryption wavefront as wide as the Internet itself. DNS, as the map of the Internet's territory, is seen as especially sensitive and there are now several competing encryption standards waiting to be deployed. In this short talk, Dr. Vixie will explain the original problem, describe the protocol-level solutions, and then show how vendors like Google, Mozilla Corporation, Microsoft, and Apple are deploying these technologies across their product lines. Opinions may also be offered.

Dr. Paul Vixie (Twitter: @PaulVixie) is an Internet pioneer. Currently, he is the Chairman, Chief Executive Officer and Cofounder of Farsight Security, Inc. He was inducted into the Internet Hall of Fame in 2014 for work related to DNS and DNSSEC.
