Adversary Emulation Plans
To showcase the practical use of ATT&CK for offensive operators and defenders, MITRE created Adversary Emulation Plans. We previously released a plan for APT3 (as well as an accompanying field manual) and anticipate that we will release additional plans in the future.
CALDERA
CALDERA is an automated adversary emulation system that performs post-compromise adversarial behavior within Windows Enterprise networks. It generates plans using a pre-configured adversary model based on ATT&CK. This presentation from BSides Charm provides an overview of CALDERA.
