Enterprise Attacker Emulation and C2 Implant Development w/ Joff Thyer

Instructor: Joff Thyer
Course Length: 16-Hours
Format: Live Online or On-Demand

DESCRIPTION

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.

KEY TAKEAWAYS

• Insight into command channel architecture
• The ability to leverage different programming languages to execute custom malware
• A diversity of solutions for establishing command channels

WHO SHOULD TAKE THIS COURSE

• Penetration testers
• Any security professionals who want to know the inner workings on malware.
• This class will help any organization that wants to start emulating advanced malware to test their defenses and detective capabilities.

AUDIENCE SKILL LEVEL
