Containers allow bad actors access to an excellent delivery mechanism for malware deployment in organizations, offering a wide variety of detection avoidance and persistence mechanisms. Fear not protectors, containers also offer ways to detect these, but can be fraught with challenges. Whether you're red, blue or just container curious this workshop is for you.
In this workshop, you will get hands-on with containers and kubernetes, - starting with introductory content - learning how they work, where and how to hide or find things, how to identify indicators of compromise, indicators of attack, and how to apply analysis to gain a deeper understanding of container malware and what is going on inside containers.
This workshop will utilize the Google Cloud Platform alongside command line operands and a small amount of open source tooling to learn both offensive and defense techniques on containers. By the end, you’ll have a solid mental model of how containers work, how they are managed and deployed, and be equipped with the ability to analyze container images, identify problems, attack container supply chains and identify familiar patterns. Ultimately, these skills will allow you to generate valuable insights for your organization’s defense or aid you in your next attack.
This course is designed to take you deep into the world of containers, making tooling like Kubernetes much more intuitive and easy to understand.There’s lots of labs which will be used to reinforce your learnings,in both attack and defense and the course comes with very detailed notes and instructions for setup which you can repeat on your own time. This course will provide references to scripts that make certain tasks easier, but we will be challenging you to learn the process and reasoning behind them rather than relying on automation.
Attendees will be provided with all the lab material used in the course in digital format, including labs, guides and virtual machine setup.
Skill Level: Beginner to Intermediate
Prerequisites for students:
- None! the class is well designed to allow those with little to no linux, kubernetes or cloud familiarity to follow along, but a basic familiarity with Linux and terminal will allow attendees to focus on the work.
Materials or Equipment students will need to bring to participate:
- A Google Cloud free tier account (basically a fresh gmail account)
- an internet connected computer
- We will send out instructions to attendees prior to the class, so they can be ready on the day.

He now works professionally as a red team member and cyber security researcher at a large financial institution.
