Brute Ratel (BRC4) is a software developed by Chetan Nayak (paranoidninja) . It is a highly customizable C2 framework which simulates adversaries and red team operations. Adversarial simulation can be used to simulate various threat actors and their TTPs to find gaps within the organizational network. Brute Ratel has advanced post-exploitation capabilities which can emulate different stages of an attacker killchain. These abilities are mapped to the MITRE framework in a graph format to train the Security Operations Team against real world attacks.
