As a cyber security defender and investigator, we often just get to analyze an environment that suffered a ransomware attack after the ransomware execution, where we are trying to make our way back in time to understand the scope and initial infection vectors of a breach. However, knowing how attackers operate and having an understanding of their tools can help tremendously to conduct a more effective analysis and response and ultimately lower the impact of such attacks. This is why in this workshop we will teach you how to perform the common steps of every phase in a ransomware attack scenario as the attacker, from initial infection to impact.

We will set up a basic C2 infrastructure with PowerShell Empire, and execute attack phases such as initial access and reconnaissance, persistence mechanisms, privilege escalation, credential dumping, lateral movement, defense evasion, data exfiltration, and encryption with ransomware. In every step you will also learn about the fundamental concepts that are required to conduct the attack and defend against those including hands-on analysis using Splunk, Velociraptor and forensic tools as needed. In the last part of the workshop, you will learn best practices on how to effectively conduct investigations of the attacked environment using various tools that are part of the lab setup. Upon completion of the workshop, participants will have a better understanding of the steps ransomware threat actors take to achieve their objectives, as well as the best practices for detecting and ultimately preventing ransomware attacks.

For most security teams, high operational tempo (measured in dumpster fire lumens) incentivizes analysts to stick to well-tailored playbooks that prioritize remediation at the expense of proper incident scoping and root cause analysis. Though modern endpoint security products have significantly improved host visibility, most critical incidents will require the acquisition and analysis of additional endpoint data. This course focuses on four core investigative competencies: endpoint data collection, investigative triage, incident response pivots, and root cause analysis.

Active Defenses have been capturing a large amount of attention in the media lately. There are those who thirst for vengeance and want to directly attack the attackers. There are those who believe that any sort of active response directed at an attacker is wrong. We believe the answer is somewhere in between. In this class, you will learn how to force an attacker to take more moves to attack your network. These moves may increase your ability to detect them. You will learn how to gain better attribution as to who is attacking you and why. You will also find out how to get access to a bad guy’s system. And most importantly, you will find out how to do the above legally.

Enterprises have been working tirelessly to improve their security postures through defense-in-depth approaches. Offensive teams have also been putting in long hours of research into bypassing the latest EDR’s and defensive products that keep them on their toes. Long gone “hopefully” are the days of hurdling an HTA file laced with a download cradle at a mature organization with a “Free iPad” ruse and watching your screen fill with incoming agents. An offense-in-depth approach may be applied to offensive practitioner’s looking for success against organizations well-versed in defending a large enterprise. Today’s organizations have assets in multiple geo regions, networks, cloud services, border hosts, and many of them are tied to the internal network in some way. This course aims to help offensive practitioners successfully exercise their client environments from a multi-faceted approach using the latest TTPs blended with esoteric practices to gain the upper hand on your assessments.

“Security” is arguably one of the most challenging disciplines to move from being an individual contributor (IC) to being a manager. While security ICs can perform most tasks in isolation, a manager needs to regularly interact with people both inside and outside of the team. Further, “security” has its own language which can be completely foreign to people outside of the discipline. How do you take security concerns and convert them into a language that senior leaders and “C” levels can understand? Honing these skills will be the primary objective of this course. In this course, we will cover all of the steps needed to stand up and lead a security team within an organization. We start with a clean slate so that every aspect gets covered. If you are in an environment that already has a security team, this can help fill in the gaps. This course will have a heavy focus on how to integrate the security team with the rest of the business units. We’ll look at strategies for increasing funding, as well as converting “security risks” into “business risks” so they are better understood by the organization’s leadership. The course includes a lot of collateral like a full set of pre-written security policies. The goal is to help you build an effective security team in as little time as possible.
