Offensive cyber security operations training

Offensive Cyber Security Operations: Mastering breach and adversarial attack simulation engagements

DEF CON Training - Las Vegas

11-12 August 2025


What you will learn

The hands-on training has been created to provide the participants with a better understanding of offensive security operations, breach and adversary simulation engagements. The goal is to enable the participants to simulate their adversaries based on the industry which their organization is in. Both known and unknown adversaries.
The participants will learn to emulate various threat-actors safely in a controlled, enterprise level environment. Also, the training would help the participants to simulate the unknown adversaries by choosing a wide variety of offensive tradecraft, TTPs and planning attack simulation engagements effectively.

The training would provide the participants access to a breach simulation lab range, where they would be able to perform a full red team-attack simulation scenario in guided mode. Each step of the attack chain would be explained along with the TTPs used, starting from initial access to exfiltration.

Learn advanced breach and attack simulation

The participants will learn to build and simulate various threat-actor and attack profiles safely in a controlled, enterprise level environment. The training would help the participants to simulate known and unknown adversaries by choosing a wide variety of offensive tradecraft, TTPs and planning attack simulation engagements effectively.
