MITRE ATT&CK is a cybersecurity framework and knowledge base, built from both publicly available Cyber Threat Intelligence (CTI) and community contributions.

ATT&CK uses a common language to describe adversarial behaviors, abstracted to an operational level. This helps Cybersecurity teams to connect countermeasures to adversaries’ perspectives.

ATT&CK stands for Adversarial Tactics, Techniques & Common Knowledge.
