Linux is everywhere– running in the cloud, on cell phones, and in embedded devices that make up the “Internet of Things”. Often neglected by their owners, vulnerable Linux systems are low-hanging fruit for attackers wishing to create powerful botnets or mine cryptocurrencies. Ransomware type attacks may target Linux-based database systems and other important infrastructure. As attacks against Linux become more and more common, there is an increasing demand for skilled Linux investigators. But even experienced forensics professionals may lack sufficient background to properly conduct Linux investigations. Linux is its own particular religion and requires dedicated study and practice to become comfortable.

The Enterprise Forensics and Response course is designed to provide students with both an investigative construct and techniques that allow them to scale incident response activities in an enterprise environment. The focus of the lecture portion of the course work is understanding the incident investigation process, objective oriented analysis and response, intrusion analysis and an exploration of attacker Tactics and Techniques. The technical portion of the course will focus on how to conduct incident investigations at enterprise scale using the remote evidence acquisition and analysis tool Velociraptor along with other free and open-source tools. The focus of the technical portion will be on extracting usable Indicators of Compromise (IOCs) related to specific MITRE ATT&CK tactics. For example, students will be instructed on extracting and analyzing evidence related to the Execution TA0002 of malicious code or LOLBAS. From here, they will be tasked with addressing containment and eradication measures. This course will combine technical elements along with lecture that provides students with both an investigative construct and techniques that allows them to analyze evidence and provide stakeholders with data necessary to limit the damage of modern cyber-attacks.

Antisyphon: Enterprise Forensics and Response

As penetration testers, we all have a need to establish command and control channels in our customer environments. This can be done under the guise of an “assumed compromise” context or in a more adversarial Red Team context. The age of endpoint detection and response (EDR) solutions and application whitelisting has created significant barriers to commodity/well known malware deployment for adversarial exercises. This class focuses on the demonstration of an Open Command Channel framework called “OpenC2RAT”, and then developing, enhancing, and deploying the “OpenC2RAT” command channel software into a target environment. Students will learn about the internal details of a command channel architecture and methods to deploy in an application-whitelisted context. The class will introduce students to blocks of code written in C#, GoLang, and Python to achieve these goals. In addition, the class will introduce some ideas to deploy existing shellcode such as Cobalt Strike Beacon or Meterpreter within a programmed wrapper to enhance success in the age of modern endpoint defense. Many of the techniques introduced in this class can be used to evade modern defensive technologies.

For the luckiest of enterprises, the awareness of an insecure environment is proven not in public discord after a breach but instead by effective security penetration tests. Time and time again Jordan and Kent have witnessed organizations struggle with network management, Active Directory, organizational change, and an increasingly experienced adversary. For new and legacy enterprises alike, Defending the Enterprise explores the configuration practices and opportunities that secure networks, Windows, and Active Directory from the most common and effective adversarial techniques. Have the confidence that your organization is prepared for tomorrow’s security threats by learning how to defend against network poisoning, credential abuse, exploitable vulnerabilities, lateral movement, and privilege escalation. Learn cost-effective mitigations to contemporary adversarial attacks. The best defended networks are those which have matured from countless penetration tests and security incidents. Learn from Kent and Jordan, two seasoned offensive and defensive security experts, to shortcut your organization’s security posture into a well-fortified fortress.

Attack Emulation tools help you measure, monitor, and improve your security controls by executing scripted attacks. Atomic Red Team is a community developed open-source library of these scripted attacks that are mapped directly to the MITRE ATT&CK Framework. There are several frameworks available for executing these scripted attacks including MITRE CALDERA and VECTR.

This class will provide an overview of the MITRE ATT&CK framework and give you in-depth, hands-on knowledge of how to execute scripted attacks that exercise many of the techniques defined in MITRE ATT&CK. You will be provided with hands-on lab instructions for emulating a variety of attacks and creating visualizations using the MITRE ATT&CK Navigator. At the end of this class, you will have the knowledge and tools to begin executing simulated attacks within your own test environment, allowing you to create and validate detections in a script-able and consistent way.
