Execution Tactics in the ATT&CK Matrix for Enterprise

The 'Execution' stage of the ATT&CK Matrix for Enterprise encompasses tactics and techniques adversaries employ to execute malicious code on target systems. This phase includes methods enabling attackers to perform desired operations on the compromised systems.


The primary objective during this stage is for attackers to successfully inject malicious code into target systems and execute it to perform malicious activities. These activities may involve actions such as file encryption, installation of spyware, and execution of malicious commands.


In the Execution stage, attackers typically leverage various methods to bypass security measures. This phase plays a critical role in the attacker's process of gaining control over and compromising the target system.


The ATT&CK Matrix for Enterprise, in the Execution stage, provides guidance to defense teams on understanding, detecting, and preventing the tactics and techniques employed by attackers. This aids organizations in enhancing their defense strategies and becoming more resilient against potential cyber threats.
