Definition
A continuously updated, shared catalog of the tactics and techniques attackers use specifically against AI systems, built on the same model as the well-known MITRE ATT&CK catalog for traditional cyberattacks. Security teams and tool vendors use it as a common vocabulary to describe, test for, and defend against AI-specific attacks.
Why it matters
The catalog's rapid growth — 11 new AI-agent attack techniques added in one update — is a useful gauge for boards to check whether their security program is keeping pace with a fast-moving AI threat landscape.
