TL;DR: AI agent attacks should be classified by detectability, not origin, because point-, sequence-, and state-detectable attacks demand different control classes and budgets, according to ARMO. The key operational shift is that many agent risks are only visible through per-agent baselines, cross-layer correlation, or posture controls that runtime tooling cannot replace.
Editorial analysis by NHI Mgmt Group, based on content published by ARMO: “Types of AI Agent Attacks: A Security Team’s Taxonomy”.
Key questions
Q: What breaks when AI agent attacks are classified only by origin?
A: Origin-based taxonomies explain where an attack enters, but they do not tell you whether runtime controls can catch it.
Q: Why do sequence-detectable AI agent attacks create so much risk?
A: Because every individual action can be legitimate while the full order of actions is malicious.
Q: How do security teams know when runtime detection is the wrong control?
A: If the compromise lives in standing configuration, overprivilege, memory poisoning, or slow conditioning, runtime detection is looking in the wrong place.
Practitioner guidance
- Define a detectability taxonomy for agent threats Classify each agent threat in your environment as point-detectable, sequence-detectable, or state-detectable before deciding which control family owns it.
- Build behavioural baselines per agent Track each agent's normal order, scope, and rate of action so legitimate variation does not hide hostile sequences inside ordinary activity.
- Correlate application, container, and cloud signals Join tool calls, permission use, and infrastructure events into one incident narrative so sequence-detectable attacks surface as a single chain.
Bottom line: AI agent attacks are not equally visible, and that visibility determines whether runtime detection can help or whether the risk belongs to posture and build-time governance.

Detectability is the more useful security boundary than origin for AI agents. Origin tells teams where an attack entered, but detectability tells them whether the attack can actually be caught by the controls they have funded. That is a more practical basis for program design because it maps directly to budget, telemetry, and accountability. Security teams should treat detectability as the organising principle for agent governance.
A question worth separating out:
Q: How should teams split responsibility between detection and posture for AI agents?
A: Use detection for point and sequence evidence, and use posture controls for state problems. That division keeps the SOC focused on observable behaviour while provisioning, configuration review, and memory governance handle risks that do not emit a useful runtime signal.
