DEF CON 31 (2023),
Aug. 11, 2023, 9 a.m.
(240 minutes)
Command and Control (C2) is a crucial component of modern Red Teams and Advanced Persistent Threats (APTs), enabling persistent connections to target networks and facilitating the spread of control throughout the infrastructure. This comprehensive workshop will provide an in-depth understanding of C2 concepts by utilizing the open-source Empire C2 framework. Participants will gain valuable insights into the deployment, features, and real-world application of C2 in offensive security. Attendees will learn how to leverage the powerful Empire framework to create, customize, and execute advanced attack scenarios, honing their skills as red team operators.
The workshop will cover a range of topics, from setting up Empire, understanding listeners, stagers, and agents, to exploring Empire's modules and evasion techniques. Participants will engage in hands-on exercises, building their proficiency in configuring and deploying Empire servers, interacting with clients, and implementing various listeners and modules. The workshop will culminate in a mini Capture-The-Flag (CTF) challenge, where attendees will apply their newfound knowledge in a cloud-hosted environment provided by the instructors.
